FSB stands for Front Side Bus:- The speed of the front-side bus is the basic clock speed of the motherboard. Many system components, for example the processor, the PCI and AGP buses, all run at speeds derived from the front-side bus speed. In general, a faster front-side bus means you will have higher processing speeds.

HYPER THREADING TECHNOLOGY

Hyper threading technology brings increased performance to computer users in two ways: using multithreaded software or using software in a multitasking environment. Software applications that have been written to use multiple pieces of code called “threads” view the Pentium 4 processors with HT Technology as two processors. HT Technology allows the processor to work on two separate threads at the same time rather than one at a time. In addition, applications can benefit in a multitasking environment - operating two or more different software programs at the same time when run under operating systems such as Windows XP. Both ways add up to extra performance and less waiting for the computer user.

PARALLEL PORT:
This is the port for connecting older printers to so that you don't have to buy a new printer when upgrading your pc.

PS/2:

This is simply a connector for the keyboard and mouse.

PCI USB Adapter Card:

USB adapter card simply resides on the PCI slot of the motherboard and gives additional USB slots in addition to the USB ports already available on the motherboard. If you choose a PCI USB adapter card, you wouldn’t probably need a separate USB hub on your desk, as you can connect all the USB devices to the back of your PC.

Hard Disk: (Storage)

The hard drive is where all the information on your computer is stored.

They can be either Maxtor, Seagate, Western Digital, Hitachi or Samsung.  These are all leading brands and are reliable enough. This has made them industry standard.

To decide what size hard drive you will need, you need to consider that for example an 80GB hard drive is 81,920 megabytes. Data in volume is called bytes:

1,024 Byte = 1 Kilobyte (KB)
1,024 Kilobyte (KB) = 1 Megabyte (MB)
1,073,741,824 Bytes = 1 Gigabyte (GB)
1 Gigabyte (GB) = 1,024 Megabyte (MB)

To safely install Windows XP on your computer you need approximately 5 gigabytes of space. A massive computer game may take up 1 gigabyte of space, but usually games only take up a few hundred megabytes.

Most programs range from 5 to 500 megabytes, and therefore the average computer user will struggle to use up 80gigabytes of hard drive space. However, if you download movie clips, music and install lots of games, and you may find you will need a 120gb or larger hard drive to cope with everything.

RPM

RPM (Revolutions or Rotations Per Minute) is the speed that your hard drive rotates. The more revolutions per minute a hard drive rotates, the more data it can copy/move within the given period of time. A 7200rpm hard drive can copy/move data faster than a 5400rpm hard drive.
