Whether you need it for home, school or your business, a new computer can be a major purchase. There are a lot of factors to consider like price, reliability, warranty, memory, CD drives and pre-installed software packages. This article will help you to figure out what you want, and how to get it.
1. Decide what you need your new computer for. If you need one for work, a simple, but high-quality system with Microsoft Word or OpenOffice will work out (OpenOffice can also be downloaded for free, if it doesn’t come with the Computer). If you need a home computer, or a family computer, a simple, but decent quality system is what will work. If you’re a huge media fanatic, and you work with media, a decent to high-end quality computer is right for you. And as for gamers, you’ll want a gaming PC.
Buying a DVD drive can sometimes be a confusing task. Below we have listed important considerations to look at when considering purchasing a DVD drive.
Before considering purchasing a DVD drive it is also good consider the other available options.
CD-R – CD-R, or CD Recordable, drives allow you to do everything that a standard CD-ROM is capable of doing, but at the same time allows you to create your own CDs for backup. An excellent solution for anyone that is in need of a CD-ROM and backup solution. Tips on buying these drives can be found on our CD-R and CD-RW buying tips page.
CD-RW – Like a CD-R drive, a CD-RW (CD Read/Write) drive allows you to read and write to a CD-RW disc thousands of times instead of once like a CD-R drive. While a little more expensive, this is another great solution for backups. Tips on buying these drives can be found on our CD-R and CD-RW buying tips page.
DVD – DVD, or Digital Versatile (video) Disc, allows a computer to not only do everything that a standard CD-ROM drive is capable of doing, but at the same time is capable of reading DVD
Recently I set out to find a new desk for my computer to rest on and came across a lot of ideas that I thought were worthy enough to share. Actually the search was tough. I mean, I know there would be a lot of people out there who would be happy with huge desks that house a nook for every peripheral… (like the one below)
but somehow they just don’t work for me. Design wise, I am more of the minimalist so naturally the ones I tend to like also favour this type of style. These minimalist computer desks we are going to feature are light weight, easy on the eyes and most of them are as sleek as the technology they are designed to hold.
OneLessDesk from Heckler Designs has a 2 deck design and takes up merely 12 inches of space when put away. The company’s pitch for the product actually sounds convincing.
At one time, you needed a desk that could fit a mountain of paper, a two-foot-deep monitor, printer, and a CPU the size of a Labrador. Today, your computer is an inch thick. You have moved forward. It’s time
When purchasing a sound card, there are several factors that can complicate and sometimes not allow you to install your sound card. Before purchasing a sound card, it is important to take the following into consideration.
Ensure that you have the available connection on the computer. Sound cards are available as both PCI and ISA.
PCI – Today, most cards available are PCI; if you plan on using your sound card for such things as playing games and watching DVD movies, it is recommended you at least get a PCI sound card.
ISA – Today, ISA cards are relatively cheap sound cards, which allow users that may not have as much money to have sound on the computer. In addition to being a cheap sound card, purchasing an ISA sound card will keep an additional free PCI slot available.
In addition to verifying your computer has the available connections, it is also important to look to see if your computer has a sound card that is built onto the Motherboard. Verify that this sound card can be disabled or will be disabled when the new sound card is installed. Additional information about on-board audio can be found in document
Flat Panel is a relatively new technology when compared to the CRT or standard monitor technology and is now available for desktop computers. With new technology comes new important considerations to look at when purchasing a flat panel solution.
Before looking at what configurations you need to look for when purchasing a computer Flat Panel, it is important to know if you want a CRT or a Flat Panel and LCD monitor.
CRT Today, one of the most commonly used technologies for computer monitors. CRT, or Cathode Ray Tube, is a technology much like what you will find on most TVs. CRT monitors are an affordable solution but are bulky and very heavy.
Tips on buying a monitor can be found on our Monitor buying tips section.
LCD LCD, or Liquid Crystal Display, monitors are similar to what is found on portable computers. LCD monitors overall display much sharper of an image, are lighter and more space efficient; however, they are much more of an expensive solution for desktop displays.
Dimensional Size When looking at LCD and Flat Panel displays, one of the most noticeable and considerable reasons for purchasing a Flat Panel is its size. As you will
Pictures on a computer display or the process of creating pictures on a computer display. The term came into use when there was still a distinction between computers that could display only text and those that could also display pictures. This distinction is lost now that almost all computers employ a GRAPHICAL USER INTERFACE.
Since a computer can ultimately deal only with binary numbers, pictures have to be DIGITIZED (reduced to lists of numbers) in order to be stored, processed or displayed. The most common graphical display devices are the CATHODE RAY TUBE inside a monitor, and the PRINTER, both of which present pictures as two-dimensional arrays of dots. The most natural representation for a picture inside the computer is therefore just a list of the colours for each dot in the output; this is called a BITMAPPED representation. Bitmapping implies that each dot in the picture corresponds to one or more bits in the computer’s video memory.
An alternative representation is to treat a picture as if it were composed of simple geometric shapes and record the relative positions of these shapes; this is called a vector representation (see more under VECTOR GRAPHICS). A typical vector representation might build up a
A computer is a machine that can handle and manipulate data in accordance with the instructions, and is also able to generate visible results on a screen or monitor. Different computer do different kinds of work, a small computer that has been designed to be used by one person, at home or in an office. It is often simply called a PC.
What is a personal computer?
A personal computer is a computer small and low cost, which is intended for personal use (or for use by a small group of individuals). The term “personal computer” is used to describe desktop computers (desktops). It is often shortened to the acronym PC or microcomputer, whose meaning in English is “personal computer”. It is a very common type of machines.
Personal Computer (acronym PC) consists of a Processor (CPU), central processing unit (CPU) contains the arithmetic, logic, and control circuitry on an single (IC) integrated circuit; two types of memory, main memory, such as RAM, and ROM, magnetic hard disks (HDD) and compact discs and various input/output devices, including a display screen, keyboard and mouse, modem, and printer.
History of Personal Computer

Purchasing a computer case is not something to consider if you are buying a computer from an OEM such as Dell or Hewlett Packard. However, for those building a computer it can be an important consideration. Below is a listing of different considerations to look at when buying a computer case.
Color and case type
Today, there are a wide variety of computer case colors and case sizes for the PC. When looking at the case, consider the color of the case and its size. Most cases come in either urban white or white. Additional information about the computer chassis including the color and size can be found on our chassis definition.
Location and size
Before purchasing a computer case you should think out where the computer is going to be placed.
- Is it going to be on your desk or your floor?
- Is it going to have enough space at its location with the monitor and other peripherals possibly next to it?
- If it’s in a bedroom will it be quiet enough if left on while you sleep?
- Does the case have enough bays for adding additional hard drives or other drives?
- Does the case have the availability for slots for additional expansion cards
Random Access Memory (RAM) is the best known form of Computer Memory. The Read and write (R/W) memory of a computer is called RAM. The User can write information to it and read information from it.With Ram any location can be reached in a fixed ( and short) amount of time after specifying its address.
The RAM is a volatile memory, it means information written to it can be accessed as long as power is on. As soon as the power is off, it can not be accessed. so this mean RAM computer memory essentially empty.RAM holds data and processing instructions temporarily until the CPU needs it.
RAM is considered “random access” because you can access any memory cell directly if you know the row and column that intersect at that cell. RAM is made in electronic chips made of so called semiconductor material, just like processors and many other types of chips. In RAM, transistors make up the individual storage cells which can each “remember” an amount of data, for example, 1 or 4 bits – as long as the PC is switched on. Physically, RAM consists of small electronic chips which are mounted in
an electronic device with a microprocessor as its central processing unit (CPU).
Microcomputer was formerly a commonly used term for personal computers, particularly any of a class of small digital computers whose CPU is contained on a single integrated semiconductor chip. Thus, a microcomputer uses a single microprocessor for its CPU, which performs all logic and arithmetic operations. The system also contains a number of associated semiconductor chips that serve as the main memory for storing program instructions and data and as interfaces for exchanging data of this sort with peripheral equipment—namely, input/output devices (e.g., keyboard, video display, and printer) and auxiliary storage units. Smaller microcomputers first marketed in the 1970s contain a single chip on which all CPU, memory, and interface circuits are integrated.
As large-scale integration and then very-large-scale integration have progressively increased the number of transistors that can be placed on one semiconductor chip, so the processing capacity of microcomputers using such single chips has grown commensurately. During the 1980s microcomputers came to be used widely in other applications besides electronic game systems and other relatively simple computer-based recreations. Increasingly powerful microcomputers began to be used in personal computer systems
Purchasing a software application or program can be a big consideration, especially when purchasing advanced and usually expensive programs such as Microsoft Office or Adobe Photoshop. When considering purchasing these programs it is important that you or your staff be familiar with the program and are sure it’s going to be capable of what you need it to do.
On this page we’ve listed different considerations to think about before buying a computer software application.
Before buying any application make sure there is not a competing program that may be cheaper or even free. If available and something that’s capable of doing what you want it to do this could save you hundreds of dollars.
A good example of such a program is OpenOffice and Corel WordPerfect that would be a competitor to Microsoft Word. Both programs are an excellent choice for a word processor but can be a considerable price difference. In the case of OpenOffice, it’s 100% free.
Make sure proper documentation is included. Many programs today will include on-line documentation that is more than sufficient. However, it is also useful to obtain a manual or user guide for the software program or application.
