About Computers and Computer Companies

David H. Urmann asked:

The advent of the computers radically changed our lifestyle. Communication, researching and other works have never been any easier.

Computers are machines that work on data according to the list of instructions. Early electronic computers consume much power. Modern computers, on the other hand, are based on tiny integrated circuits. Nowadays, simple computers can be made to fit in a wristwatch and powered by watch batteries.

Generally, a computer has four main sections such as the ALU or the arithmetic and logic unit, the memory, the control unit and the IO or the input and output devices. The basic input and output, control unit, register and control units are known as the CPU or central processing unit. Early central processing units were composed of numerous circuits but now it is typically assembled on a single integrated circuit known as a microprocessor.

The Arithmetic or Logic Unit (ALU) is capable of executing two modules of operation such as logic and arithmetic. Some computers are capable of executing easier operations that can be programmed to break the complex operations, making them into easy executable steps. Hence, a Superscalar computer has multiple arithmetic or logic units.

There are numerous computer companies around the world. One of this is the Yemen Computer Company. It is the main and pioneer company of Yemen. It is the most experienced and the largest computer company in this country.

Furthermore, this Yemen based company is a computer software and hardware vendor or distributor. It also represents Intel servers, IBM products, Sun Microsystems products and POS products.

Helix Computer company can build turn-key computer systems for numerous applications. The Company production studio was constructed with a self-sufficient artist in mind. Helix production studios are capable of making videos, audios, graphics, animation and so much more.

Computers may be quite expensive but you can scout for refurbished ones such as Dell Computers that can collect their old model computers while still be installed with the latest technology. This model is great and affordable in budget terms.

Sometimes a basic computer may be enough for your needs. The bare bones model is also great if you only check e-mails, word processes and surf the Internet. Dell retails basic models for less than 500 US dollars. This basic system is a good deal for common users.

Computer Parts – No More a Hidden Business

Harry Johnson asked:

Computer parts are an important peripheral for any business houses today. Computer hardware is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware.

The use of computer is endless you can use a computer for printing reports, documents, publishing newsletters or for just printing photos. The hardware of a computer is infrequently changed, in comparison with software and data, which are “soft” in the sense that they are readily created, modified or erased on the computer.

Most computer hardware is not seen by normal users. It is in embedded systems in automobiles, microwave ovens, electrocardiograph machines, compact disc players, and other devices.

PC hardware:

A typical personal computer consists of a case or chassis in desktop or tower shape and the following parts:

Motherboard: The Motherboard is possibly the most important part of the computer. The motherboard is the foundation of any PC. All the critical subsystems, including the CPU, system chipset, memory, system I/O, expansion bus, and other critical components run directly off the motherboard. Likewise, the interconnections among these components are laid into the motherboard itself.It slots for expansion cards and holding parts including :

Central Processing Unit(C P U): It is the core of computer, it control the main processing process.

Random Access Memory (RAM): It is for Program execution and short term data storage.

Basic Input-Output System (BIOS): All computer hardware has to work with software through an interface. The BIOS gives the computer a little built-in starter kit to run the rest of software’s from floppy disks (FDD) and hard disks (HDD). The BIOS is responsible for booting the computer by providing a basic set of instructions.

Keyboard: The keyboard is one of the simplest parts of the computer to understand. This chapter goes beyond the keyboard basics, however, to show you how to do tasks such as inserting special characters or typing in another language. This chapter also looks at how to take care of your keyboard and how to take care of yourself when using it.

Power supply – A case that holds a transformer, voltage control and fan.

Storage controllers : It is of IDE, SATA, SCSI or other type, that control hard disk, floppy disk, CD-ROM and other drives; the controllers sit directly on the motherboard (on-board) or on expansion cards

Video display controller: It produces the output for the computer display.

CD – the most common type of removable media, cheap but fragile.

CD-ROM Drive

CD Writer

DVD – DVD- ROM Drive, DVD-RAM Drive, DVD Writer.

Tape drive – mainly for backup and long-term storage.

Internal storage – keeps data inside the computer for later use.

Sound card – It translates signals from the system board into analog voltage levels, and has terminals to plug in speakers.

Networking – to connect the computer to the Internet and/or other computers, to connect one to other computers you required the following thing:

Modem – for dial-up connections

Network card – for DSL/Cable internet, and/or connecting to other computers.

Other peripherals

How to Sell Used Computers

Lesley Lyon asked:

Many people sell their used computers for a variety of reasons. Some sell their used computer instead of throwing them as a trash get some money from them, while others sell their used computers to buy new computers with the latest features and technology. Not only individuals sell their used computers, but also large numbers of organizations or firms sell their used computers. They do so because the computer systems may require maintenance and repairs, after some time due to the decrease in performance seen in the computers after some years. Instead of spending more money on the maintenance and repairs they sell and gain money, as there is a great demand for used computers. Such companies easily sell their used computers online through auctions or exchange for new computers with less effort in no time.

Used computers are bought by either students who do not have good savings or earnings or they are bought by educational institutions like the schools and universities. Some parents buy used computers for their children just for browsing the Internet and to play games. For this purpose, a used computer is more than sufficient than spending huge amounts on a new computer. These target segments however require used computers in a good working condition as well as for a lesser price. Most of the used computers are sold in the online market, as it attracts all sorts of buyers. There are many numbers of online classifieds or auctions or online dealers who sell used computers. Selling used computers are a better option than throwing them as trash or keeping them in a corner occupying space and collecting dust.

The first and important step is to improve the appearance of the used computer by wiping it clean free of dust and dirt. Any buyer would get impressed by the way the computer looks, looks make the first impression. The selling price of a clean used computer is always better than the one, which is full of dirt and dust.

All the software manual, operating system and other supporting discs that came with the computer should be in tact. This will add more value, when selling the used computer and also will make the buyer consider the person who is selling the used computer as a trusted seller.

The most important thing to do before selling a used computer is to erase all the personal details or information from the hard disk or drive. Instead of just putting them in the trash folder it is very important to purge all the personal data from the computer’s memory, even invisible backup files can cause danger. A tech savvy person’s help can be got if the seller does not know how to do it. If not done it may lead to accessing the bank accounts, or emails by any unknown person leading to identity theft. For that when there is a remedy. Unused scanners, printers can also be bundled with the sale of the used computer. A buyer may sometime value it. The benefits or features of the computer can be highlighted for better sales.

Used Computers (Desktops/Laptops)- What To Look For?

Christophe Catesson asked:

Nowadays desktops and laptops are much more durable and dependable that they were just five years ago. Therefore, buying a used or refurbished computer is becoming more of a trend.

Suppliers replace their computers on average every 6 months and companies frequently upgrade their equipment. Buying one of these used or refurbished computers can save you a lot of money while still using a quite up to date technology. This is even more relevant if you are not a heavy user (i.e. most of your time on a computer is spent online, you may use a few standard applications once in a while). Even modestly priced computers will more than suffice for these types of demand.

Thinking about buying a used or refurbished desktop or laptop?

Buying a computer is not at all an easy job, one has look get detailed information of the available computers of good and reputed brands. One must take into consideration the size, color, configurations, features etc… While your computer should correspond to your personality and lifestyle, you should always keep in mind the reputation of the brand in the market. Brand counts a lot; you can render good service by the manufacturer if your computer is damaged.

Important handy Tips before buying a computer…

* Verify if the brand is reputed and always buy a good reputed brand. Read about customer service experience for that specific computer issues.

* Check the warranty/guarantee of the computer (seek out computers which still have warranty/guarantee remaining)

* Compare the price of the new model in the market with what price your buying your used computer, try to get the best bargain. i.e. a two year old computer should not be bought for more than half of its original price.

* Check if the computer is outdated (if out of production it is difficult to get spare parts)

* Is the operating system current (Windows Vista/Windows Xp). Earlier versions probably run slower (windows 2000) and would not be advisable unless your needs are limited (i.e. web surfing, Word…). In any event, stay away with computers running on Windows 98 (granted you don’t find many anymore). Also be aware of Windows Vista. Many users are reverting back to XP and that is even more obvious in the corporate world. Why? Vista looks nice but doesn’t bring many technical improvements; therefore IT managers are not willing to implement something new when what they have works just fine. Some domestic users just don’t like the new way of navigation within the Vista Operating System.

* Check if the configuration of the computer you are buying is good.

* Check the speed of the processor. If possible start the computer and see how long it takes to fully turn on. If its slow just turning on, imagine the lack of speed once you start adding software..

Additional Tips for laptops

* Is the battery life good? (search for the computers with a very good battery backup).

* Check for the screen size of the computer your buying and see to it that it is not exceeding the Normal (normally the screen size should be between 15-17). Less than that generally translates in older computers and increases the chance of age failure. Once the screen breaks, you are often better of changing the whole computer.

* Review the connectivity of the computer (Network, USB, Video, Audio…) look to it that it has a good connectivity including wireless.

* Check out the weight. Ensure the computer is light enough for you to carry.

* More details at http://www.bestlaptopsreviews.com/index.php/Used-Notebooks.html

Where to buy used computers:

* Online auctions. Pro: Often offer the best prices. Cons: Cannot validate the accuracy of the described item. No warranty. Tip 1: Some companies will offer warranty for up to two years, the cost is about 12% to 18% of the purchase price. Tip2: Buy from sellers with great feedback, do not hesitate to contact the seller with questions prior to bidding.

* Online marketplaces: Pro: Set prices and quantities – Sometime warranty is available. Cons: Prices can vary a lot, do your homework.

* http://Craiglist.com Contacting sellers on http://Craiglist.com in your local area gives you a chance to meet with the owner and physically test the computer before the purchase

Where to buy refurbished computers:

Refurbished computers can be a great way to buy as they have warranties and are generally sold by manufacturers or companies affiliated with them.

* Manufacturers websites will tell you how to buy directly from them or from their authorized sellers. Pros: Warranty, established companies. Cons: Prices are higher than regular auctions (you pay more for peace of mind)

Buying a used or refurbished computer can be a great way to save money. If you use some of the advice discussed above you can avoid many pitfalls. One last thing concerning laptops, make sure you have a good bag to protect your computer from a fatal accident. Your bag should be big enough for a 17 inch screen computer as it is rapidly becoming the norm, you will probably change your computer within a few years, the bag you may keep a lot longer.

Good Buy!

Make Great Savings by Buying Replacement Parts From Wholesale Computer Parts Dealers

Muna wa Wanjiru asked:

If you have been shopping in the market for a new computer system, you might have noticed that most branded computers today have become highly unaffordable. Sure, prices have fallen in certain sectors that contribute to the making of computers. The prices of memory have hit an all time low due to the enhancements in manufacturing volumes of memory manufacturers. The prices of mother boards and other assorted computer innards have also fallen steeply. But the fact remains that the branded computer manufacturers are in the business to make their own profits. Therefore, despite the all around falling in prices that we have been witnessing, the prices of good computers have remained more or less constant!

Does this mean that a good computer system will always remain unaffordable? Not really! If you consider sourcing your computer from dealers who specialize in wholesale computer parts. Wholesale computer parts are an excellent way to source out and build your own computer. Most people are of the opinion that wholesale computer parts are in some way inferior to the parts available in branded computers. The same was the case with me. I always believed that wholesale computer parts were a means for cheap and inefficient computer parts manufacturers to offload their inferior stock on unsuspecting customers. Until my computer broke down recently that is. When I took it to the authorized dealer, I got a quote that was very high. Being unable to spare that much cash, and being desperately in need of having my computer restored, I grudgingly made my way to a nearby wholesale computer parts dealer.

What I saw there amazed and astounded me. This wholesale computer parts dealer has his own repair service. And when they opened up my computer and diagnosed the problem, the repair quote I got was a fraction of what the authorized dealer had given me. I was naturally curious as to what had created the difference and suspiciously eyed the wholesale computer parts on display. But the dealer opened up my computer to show me that the replacement parts would be the very same that my existing computer had. As installed by the original manufacturer. When I asked him how this was possible, he explained the wholesale computer parts business to me.

Apparently, most computer parts manufactures manufacture more parts than required by an order from a branded computer manufacturer. This is an in-built quality control feature in order to ensure that a sudden spurt in demand or a quality crisis can be handled quickly and efficiently. When the order is processed without incident, the excess parts are offloaded to wholesale computer parts dealers for a huge discount. These wholesale computer parts dealers then sell these equally good computer parts for a discount to users like you and me, who know better and are willing to invest the time and effort that it takes to build our own computers. Which means, that by buying the parts directly from wholesale computer parts dealers, we stand to make great savings!

The next time you want to go in for a computer purchase, do consider new source apart from the regular computer manufacturers. Consider sourcing out your computer from the wholesale computer parts dealers. And you’ll never regret your decision.

5 Easy Steps to Green Computing

Nikhilalex asked:

You can’t pick up the newspaper, turn on the television, or surf the Internet, without being bombarded by hot topics such as global warming, rising greenhouse gas emissions and the world’s energy crisis. You’re doing your part to help out by recycling and carpooling, but did you know that one of the most effective ways to improve energy management, increase energy efficiency and reduce waste starts with your computer?

According to the U.S Environmental Protection Agency (EPA), computers account for a relatively large portion of our electrical consumption—about 2% nationwide. The growing use of computers has caused a dramatic increase in energy consumption, which puts negative pressure on the environment. Each year consumers (and businesses) purchase more computers and put to them to use, but it’s not just the sheer number of computers that is driving energy consumption upward. The way that we use computers also adds to the increasing energy burden.

By adopting conservation practices and changing the way you use your computer, you can help make a difference in the environment – and your own wallet. If you’re ready to take the “green computing” initiative, here are a few simple tips to get you started:

Buy “Energy Star” compliant peripherals

Before you buy, check with the manufacturer or on the Energy Star web site.

Enable power management features

Thanks to the U.S. Environment Protection Agency (EPA), personal computer systems purchased today can be easy on energy. These “Energy Star” computers and monitors can be programmed to automatically “power-down” to a low power state when they are not being used. These efficiency gains can be achieved without any sacrifice in computing performance.

The EPA has estimated that providing computers with “sleep mode” reduces their energy use by 60 to 70 percent – and ultimately could save enough electricity each year to power Vermont, New Hampshire, and Maine, cut electric bills by $2 billion, and reduce carbon dioxide emissions by the equivalent of 5 million cars.

Follow these simple steps to access computer and monitor power management features for Windows.

1. First check to see that your monitor is Energy Star compliant (see above)

2. Open ‘Display’ in the Control Panel, go to the ‘Settings’ tab, click on ‘Advanced Properties’ and choose the ‘Monitor’ tab

3. Check ‘Monitor is Energy Star compliant’ box click ‘OK’.

The recommended settings are 20 minutes for monitor sleep and 30 minutes for system sleep. Remember that to save energy with your monitor’s built-in power management system, your monitor must go to sleep (shut itself down).

Turn off the screen saver

If screen saver images appear on your monitor for more than 5 minutes, you are wasting energy! Screen saver programs may save the phosphors in your monitor screen, but this is not really a concern with newer monitors, especially LCD screens. And they certainly don’t save energy.

A screen saver that displays moving images causes your monitor to consume as much as electricity as it does when in active use. These screen saver programs also involve system interaction with your CPU that results in additional energy consumption. A blank screen saver is slightly better but even that only reduces monitor energy consumption by a few percent.

When not in use, turn off the juice

Research reveals that most personal desktop computers are not being used the majority of the time they are running and many personal computers nationwide are needlessly left on continuously. Every time we leave computers or lights on we waste electricity. Burning fossil fuels generates most of our electricity and it also emits pollutants, sulfur, and carbon dioxide into the air. These emissions can cause respiratory disease, smog, acid rain and global climate change.

Consider doing the following:

o Turn off your computer and/or peripherals when they are not in use. Turning them on and off will not harm the equipment.

o Don’t run computers continuously unless they are in use continuously.

o Turn off computers and peripherals at night.

o Look for ways to reduce the amount of time your computer is on without adversely affecting your productivity.

o Unless you require immediate access to e-mail or other Internet services, break the habit of turning on all your computer equipment as soon as you enter the office each day.

o If practical, informally group your computer activities and try to do then during one or two parts of the day, leaving the computer off at other times.

o Avoid using the switch on a powerstrip to turn on all your equipment.

o If you use a laser printer, don’t turn your printer on until you are ready to print.

o Turn off your entire computer system (CPU, monitor and printer) or at least your monitor and printer when if you are going to be away from the computer for a little while.

Take proper care of your laptop batteries and dispose of them carefully

Follow the guidelines in your laptop manual, such as removing the AC adapter when fully charged, or totally discharging before recharging, to maximize the working life of a laptop battery. Many types of rechargeable batteries contain potentially toxic materials such as Cadmium, so dispose of them properly and carefully.

Don’t throw your old computer away

Globally over 35 million PC’s are thrown away ever year – yet there are many companies now recycling or reconditioning components or whole computers. Don’t throw it away. Your old computer might be worth something either to a dealer, a local school or a charity.

The Best And Simplest Computer Virus Protection

Maxwell Z. Rubin asked:

Many computer users live in fear of computer viruses. It is true that computer viruses can do a lot of damage that most likely could have been easily prevented – that is if they had a working up to date virus program.

First of all be reassured. Even if your computer is “wiped clean” or “wiped out” you may not be in the doghouse so to speak. If you use the computer mainly for browsing on the internet, then it is only a matter of a reinstall of windows to get you on the web again. Your computer is only a device to access the internet. It is as if you get a new phone to plug into the wall or a new TV to watch the channels that were there that were and are still there.

Your email most likely is safe as well. If you use a web based mail program like hotmail or yahoo to access your email – then your email is most likely still sitting on that company’s server in California, Bombay India or somewhere else in the world. If Microsoft goes bust, your lost email will be the least of your problems in today’s world. If you use a mail reader client like Microsoft Outlook or Outlook Express, then at the worst your new email is sitting safely at that computer mail server computer.

Next it can be can be said that we have gotten off easy with computer viruses. Well at least up the present. Computer viruses can be written by its developer to do anything the developer wishes. For the most part computer viruses have been relatively innocuous. The majority of the computer viruses that you will encounter, at present, in your career as computer user, are of the “Trojan” variety and are not that mean or destructive to your computer. . Trojan antivirus are computer viruses that patiently sit in wait for a signal from a control computer, somewhere in the world, to be part of a large scale computer attack on some remote computer to overwhelm that service and disrupt its function on the internet.. You may have heard such tales in regards to C.N.N. or Amazon having their internet service being knocked out of service maliciously. Believe it or not it is estimated that up to 50 – 60 % of most computers have these Trojan viruses sitting quietly and patiently in their computers and do not know and most likely will never know that they are infected.

The first rules of computer security is that if the computer is used at for storing delicate, sensitive or important data – then that computer should not be attached to the internet or have an internet connection. It’s as simple as that. If you don’t talk then you can never be accused of blabbing.

As an example there was a firm that was allowed access to very confidential government data as part of its business plan. . It was made very clear, by the government agency involved as a sponsor, that this data was most confidential. I f this information was somehow leaked or placed on the internet then dire consequences would occur. What could be a simpler message? And yet in this case, all for the convenience of the owner of the firm, the computer was directly attached to a fax computer. Even of that computer was only connected to the fax max machine computer for a split second that is all it would take for the wrong information to “get out”. Politicians follow the rule of deniability. Why shouldn’t you. ? Make your life trouble free. If the computer is nowhere near the internet in any way shape or form you can never be blamed. Simple as that.

The most important factor in computer antivirus protection is not so much the product used or installed – and there is no shortage of very reasonable computer antivirus products. The most important factor for computer antivirus security protection is that updates for the antivirus be done on a regular basis.

When you purchase a new antivirus product or complete a renewal product that is in essence what you are doing. It as if you are buoying a magazine subscription for the year.

By purchasing the subscription you are now entitled to antivirus updates for the coming year. New computer viruses are coming out “all the time”. It does you little good to be protected from last years plague. You need to be protected from the current viruses that are causing the havoc now.

Make sure that you either have a copy of an antivirus installed that has current virus definitions or if you purchased a commercial product that you have a valid subscription that allows you access to the current up to date virus lists. Next be sure that you run regular full comprehensive antivirus scans to detect and quarantine new and perhaps dangerous computer viruses. More featured commercial antivirus programs may do this automatically.

In the end most of life comes down to preparation and attention to detail. A major role of fire departments is not only to fight fires but fire prevention. Your computer antivirus protections scheme and program should be likewise

The World of Computer Speakers

David H. Urmann asked:

The most well known speaker in the world is out to give you yet another stunning performance. Computer speakers are such in demand in the market now. People using the internet, teenagers hooked with their on line games are the primary users of this electronic device. Their ground-breaking inventions and improvements will surely fascinate you.

A computer speaker is a built-in device that generates the sound from the computer. This kind of speaker is designed for PCs or personal computers. A lot of different computer speakers can connect via a jack, USB, RCA connectors, socket and plug. They are commonly designed as attractive, small and versatile.

Their FX series possess a remarkable sound from the FX satellites’ REAL two-way system. This means that each satellite has two drivers that are both active. The beauty of this new innovation is that the FX 4021 and FX 5051 can be mounted on the wall. Thus, the first 5.1 system of FX5051 can offer the advantage of having a USB plug -and -play connectivity, which adds to its ease of use.

Comparing the FX 4021 and the FX 5051 specifications, with regards to its unique features are as follows:

FX 4021 uses an isobaric subwoofer with dual 5.25 inches woofers. Aside from this, the rest of the specifications are already similar to the FX 5051. Hence, the FX5051 is similar on some specifications with the FX 4021 but it has a better isobaric subwoofer with dual 6.5 inches woofers, a USB 5.1 connectivity, digital hardwired controller for stand-by, master volume, bass, treble and centre controls.

Comparing this high end speaker, FX6021, with a high performance speaker like the VS 4221 that possesses an impressive bass capable of registering on your Richter scale, they are still not on equal footing. This is due to the fact that the VS4221 has a 3 inch driver for a warm, uniform sound, capable of surrounding an entire room. The stunning result would be robust, rich sounds that only very few woofers can match.

Thus, a wide selection of speakers is now available and they differ depending on the user’s demands and needs.

Is your Computer Extremely Slow? Here Are Some Tips To Improve Its Performance

Howard Platt asked:

your computer extremely slow? Are you wasting more time waiting then you are actually working? This can be completely frustrating and at one time or another all computer users will experience their computer being extremely slow. Fortunately there are some things that you can do to fix a slow computer.

When you first purchase your computer it runs fantastic, you can open and close programs quickly, you can browse the Internet with speed, going from website to website, opening and closing pages without a problem, but after awhile you begin to notice a change. Your computer isn’t running with the same type of performance it had when you first purchased it and you spend more time waiting because your computer is extremely slow. Well if your now slow computer has you wanting to throw it out the window lets see what we can do to remedy the problem.

One of the many causes of a computer running extremely slow is that you have very low available disk space on your hard drive. Your hard drive needs to have an adequate amount of free space to allow for temporary files and it must also be able to accommodate your swap file. If your swap file cannot accept temporary files it will result in a slow computer. A swap file is just a file that is stored on your hard drive and it is used to store information that is not being used by your computers RAM (random access memory) at any particular moment. If your computer is extremely slow, your hard drive could be lacking the room for your swap file to grow, keeping it from storing more temporary files which in turns frees up more of your memory.

We can help your slow computer by regaining some of the space on your hard drive, in a couple of ways. The first step you should take is to run the disk clean up option that is right inside your system tools. To get to your system tools you would click on your “Start” button, then open “All Programs,” then click on “Accessories” and choose “System Tools” from the list and that opens up another list that you will choose “Disk Clean Up” from. Once you have Disk Clean Up opened you just double click on it and it will do all the rest. Now try using your slow computer for a day or two and see if it has made any improvements on your computers performance.

Now is your computer extremely slow even after you completed the Disk Clean Up and put it to use for a day or two? If so then we will have to use another trick to try and correct the problem. Your computer will contain folders that have files in them that are used for uninstalling Microsoft Windows updates. When ever you update your computer with Microsoft updates you simultaneously download the uninstall files which will allow you to uninstall any updates that you decide you don’t want for one reason or another. Well if your computer is extremely slow you may want to consider deleting these uninstall folders because they can take up a significant amount of hard drive space resulting in a slow computer.

You are going to want to locate and delete these uninstall files and to do that you must first open “My Computer” and inside My Computer your going to open your “C: Drive.” Now inside your C-drive you will open “Windows” or it may be called the “Winnt Folder” and when this folder is open you will see folders labeled $NTUninstall, now any of these folders that are older then a month you can delete. That should have cleaned up a lot of unnecessary files and folders, freeing up quite a bit of hard drive space. This will usually correct any problems causing your computer to be extremely slow.

Now, if you find yourself constantly complaining because your computer is extremely slow you now have a couple of tricks up your sleeve that you can use anytime that should help correct the problem.
