Knowledge about computer

Ask youself ,will I buy this PC for what purpose, many will have the PC for games ,or just typre and print.PCs have become a staple in every home. Without PCs, you will find it hard to stay connected and to even do the work required of you in school or in the office.
With so much PC packages being shoved to our throat every time we go to department stores and computer shops, you’ll really get quite confused on what you really need and what PC package will fit your budget and lifestyle. To help you through this dilemma, here is a brief backgrounder of the parts of PCs that you should get to know.
Processor.
This is one of the three primary components of your PC. The processor is the part that determines how fast your computer process information. Intel is still the leading brand in processors but competitors such as American Micro Devices (AMD) are slowly catching up, offering cheaper alternative. In shopping for a processor, one should consider the following:
Clock speed – this will show the number of instructions that a computer can execute in a second. This usually comes after the brand name. Processors nowadays are already set at the gigahertz range.
Cache memory – this stores the data that were previously accessed. This simplifies the work of the computer as it would not take twice as long to access information already stored in memory bank. Without a cache memory, much of the work will fall on the RAM (Random Access Memory).
Operating temperature – some processors easily heats up. Before buying, make sure that you have asked about the operating temperature just in case you need to buy additional fans or put the computer in an air-conditioned room.

RAM (Random Access Memory). -RAM serves as the temporary memory of the PC, containing information that are needed for the computer and the programs to function. In addition to processors, RAM also determines the speed of the computer. The higher the RAM, the faster the computer is in accessing information and responding to commands.
Motherboard.-This is where all the parts of the PC’s CPU (Central Processing Unit) are attached. Some motherboards already have videocards and soundcards embedded on it while others don’t. what is important however is to choose a motherboard that is compatible with your RAM and processor. Incompatibility of PC hardware can cause major problems and may even lead to the breakdown of your computer.
Hard disk drive.-This is the part where you store all the information in your PC. Picture a floppy disk with much much larger storing capacity. The hard drive serves as the permanent memory of your computer. Here you install all your programs and save all the documents that you need. It is also important that you buy a hard drive with really big capacity especially now when people are so used to storing multimedia files that may use up a lot of hard drive space.
Video cards.-This is the part of the computer which determines the quality of the multimedia images that you will view. The higher the memory of the video card, the better is the picture quality and the colors. Also, video cards are also responsible for how fast multimedia images are accessed. This is especially needed if you use your computer for multimedia activities such as watching a movie or playing video games.

Crude specifications for nowaday.(very demanding for web 2.0 type with rich of javascripts and plugins)
1.for normal surfing of the internet. Pentium 4 ,single or double core CPU ,about 2.4-3.0 gigahertz clock speed ,256 MB of rams, with 16 megabyte video card memories ,and 40-120 gigabyte hard drive. That should be OK for now.
2.for elite internet surfer or streaming audio or video across internet. can use same speed of CPU or UP to 3.2 with quad core ,512-1024 MB of rams,with 32-64 megabytes of video card memories.
3.picture or video editor. Need at least double to quad core CPU or even XEONs ,3.0 GHz up ,1-2 gigabyte rams and very high speed hard drive like SATA type .
