The Motherboard's FSB (Front Side Bus) speed is an important indicator of a Computer's speed.

It is a bi-directional bus (i.e., interface) that carries all electronic signals to and from the CPU to the components - Hard Disk, Main Memory, etc.

The faster the FSB, the faster your Computer! FSBs today come at speeds of 667 MHz, 800 MHz as well as 1 GHz

Motherboard

Current technologies here are ISA and SATA, with Hard Disk speeds being 5400 RPM, 7200 RPM and 10000 RPM.

Of the two technologies, SATA is faster.

Hard Disk

Details about Memory technologies would take too long to explore!

EDO, SDRAM, PC100, PC133, PC800 RDRAM and DDR DRAM are memory technologies, past and present.

As far as your purchase decision is concerned, the higher the speed (Memory speed is internally measured in nanoseconds, and the speed it communicates to the FSB is measured in MHz) of the Memory, the faster your computer.

Current Memory technology is DDR SDRAM and speeds are 1GHz to 1.3 GHz.

Main Memory

All Motherboards today come with built-in Graphics and Sound. This was not the case earlier.

However, the Graphics and Sound that is built into the motherboard is very basic.

Most of the graphics-intensive programs - AutoCAD, Adobe Photoshop / CorelDRAW and the likes, would run much faster with an add-on 3-D Graphics card with dedicated memory.

If you plan to run more that a Word processor, e-Mail, Browser and such stuff, a dedicated Graphics Card, with 512 or 1024 MB of dedicated Video RAM is a must!

Similarly, if you are into music editing/ making movies/ audio CDs/ DVDs on your Computer, you must go in for a dedicated Sound Card. Sound Blaster has remained the market leaders and preferred brand in the sound cards segment for many years now!

Graphics and Sound

Today, you have a choice of Optical Drives. Here are the choices you have:CD-ROM Drive (Read CDs)Combo Drives (Read and Write CDs, Read DVDs)Super Drive (Read and Write CDs as well as DVDs)Blu-Ray Drives (Read and Write CDs, DVDs as well as the

new Blu-Ray Disks)A plain vanilla CD-ROM Drive is now passé, while a

Blu-Ray Disk may be a costly luxury at the moment, for, its prices will continue to fall.

At the moment, the best bet is definitely to go in for a Super Drive that will let you play as well as record on both CDs as well as DVDs

Optical Drive

Lastly - and equally importantly, your choice of Operating System will also affect your specifications.

While Windows XP would run quite well with 512 MB Memory, you will require a minimum 1 GB, if your choice is Windows Vista Business:

It is recommended that 2 GB RAM is a minimum if you are running Vista Home Premium, Vista Business or Vista Ultimate.

What is the memory requirement for Windows 7?
