subject: Guide To Buying A Personal PC [print this page] PCs have become very popular and, in most households, have become a part of the daily routine. PCs have been seamlessly integrated into our busy days, mainly because of their immense capabilities to process data. They are in ubiquitous, and are in high demand. Between 2002 and 2007, a total of One Billion PCs have been sold worldwide. This staggering number is proof of the adoption of PC systems in our society.
PCs can help us to do many things. They help us to work and play, and they specialize in various fields, such as entertainment and designing. Therefore, choosing the correct PC to buy, based on your needs, can be a hard task. That is why I have compiled a list to guide potential customers when buying a PC:
When buying a PC, the important components to review are:
Processor Persons need to assess the capabilities of a processor and make sure they fit their demands. The clock speed, amount of cores and L1 and L2 cache are a good indicator of processors strength and their ability to process data. For example, an AMD 4 core processor with a clock speed of 2.6 GHz and a L1 cache of 3mb would be better for designing or gaming, while an Intel 2 core processor with a clock speed of 3.2 and a L1 cache of 2mb would suit a person who wants entertainment.
Memory In a PC, Random Access Memory (RAM) is used to store data that is needed for processing. Therefore, RAM is a very important component with regard to PC speed and functionality. Today, most RAM chips are DDR3 (that is Double Data Rate Three Synchronous Dynamic Random Access Memory) because of its high performance capabilities. Although RAM is very costly, some persons who are on a tight budget may choose DDR3's predecessor, DDR2. The recommended amount of RAM is 4 GB, to have all of the programs running smoothly.
Video Card Some persons may need to run programs that require special third dimensional acceleration or some other excessive demand on hardware, such as a game or graphics design program. While the average person can cope with the integrated graphics card, sometimes, the Graphical Processing Unit (GPU) may be insufficient for a user that needs more from their PC.
Hard Disk The hard disk is where all the user's data and information is stored. Hence, the user should practice caution when picking a Hard Disk for a PC. In a desktop, a minimum of 320 GB would be fine, along with an external Hard Disk to back-up data. The average hard disk operates at 7200 Revolutions per Minute (RPM), but for users who want more performance, they can choose one with 10000 rpm or more, or a Solid State Drive.
These tips should be sufficient for a consumer to have a good insight as to the specifications that they would like included in their Personal PC.
