Sound and graphics are compressed to reduce file size, which saves storage space and bandwidth, allowing for quicker downloads and smoother streaming. Compression also facilitates faster processing and transmission, making media more accessible on various devices and platforms. Additionally, it helps maintain a balance between quality and performance, ensuring that users have a better experience without sacrificing too much fidelity.
Graphics are compressed to enable more efficient storage and perhaps faster loading in some cases.

Unless you are a sound editor and/or a real sound snob you don't need a separate sound card.
its so simple all you do is go to online sound card and graphics card in windows vista.
