How To Choose The Right Computer, Laptop Or Notebook For You
Making the right choice when looking to buy new computers, laptops, notebooks or other hardware devices can have a big impact on your long term productivity and satisfaction with the device. This article will try to describe the basic and most important things to check for when making a purchase and in so doing explain the basic components of these machines.
There are two main questions that must be answered when purchasing hardware devices like computers, laptops, notebooks and so forth; these are firstly, in what way will you use the device? And secondly, how much are you willing to spend?
At a basic level all the computers that you decide amongst will share some building-block components, so it is important to know what these are, what they do and how they can affect performance.
The central “brains” of a computer is the CPU, Central Processing Unit, or Processor; this determines the speed of the machine The two most commonly found CPU’s are Intel’s Celeron and Pentium family and AMD’s Duron and Athlon. A rough approximation of the effectiveness of a processor is provided by its clock speed which is usually measured in gigahertz or megahertz, generally the higher the clock speed the higher performing the processor will be. A word of caution here; the market leading processor at any particular time may not always be the smartest investment as the very top-end of performance is often disproportionately expensive, so opting for something that is not nece ssarily the newest release may be prudent.
RAM is the memory used to perform tasks on the machine, like a fast access temporary storage system. It works only when the computer is turned on and otherwise retains no information. As with the CPU, in general the higher the RAM figure, the higher the performance of the machine will be.
In contrast to RAM, the hard disk is a long-term storage component and retains information even when the machine is turned off. Whilst the computer is running, the hard disk will typically exchange information with the fast access RAM so that the CPU can have quicker access to it. Once again, the larger the hard disk the better.
Computers will have separate monitors and these can be split into CRT monitors which are large and bulky, and LCD monitors which are slim. The best monitor size to go for will vary depending on what you intend to use the computer for.
Finally, the graphics card is responsible for the quality of the image on the screen of these devices. The device will control the resolution of the image shown and the refresh rate. For a flicker-free display it is best to opt for a high refresh rate.
Whilst there are many other features to consider when purchasing computers, laptops, notebooks etc,, the basic and most crucial hardware elements have been outlined. For a computer that provides the best value for money, it is best to try and match the specification of the hardware components with your computer usage needs.
