Will the PC change in 2005? Not much.

Your computer system will stay about the same this year, but you can expect changes in 2006 when Microsoft is expected to release a new operating system code name Longhorn.
You might find some changes in computer chips and memory and you might see new hard disk and DVD technology coming out reports PC World.
A disk technology called Serial ATA is also becoming established. It includes a feature called Native Command Queuing (NCQ), which allows a drive to manage multiple commands from the PC in whatever order it deems most efficient, rather than the order in which they were received. It can deliver a substantial performance boost to users, and that’s good news for data-heavy applications such as those involving video.
