~ Tim Berners-Lee aiming to convince skeptics the internet will Increase the joy of the inhabitants.

The motherboard connects all processor, memory and peripheral units jointly. The RAM, graphics card and processor are generally mounted straight onto the motherboard. The central processing unit (microprocessor chip) plugs right into a CPU socket, even though the memory modules plug into corresponding memory sockets. Some motherboards hold the movie Display screen adapter, sound along with other peripherals integrated on to the motherboard, while others use growth slots for graphics cards, network cards, or other I/O units.

Optical storage equipment are slower than magnetic disks, but These are well matched for generating learn copies of program or for multimedia (audio and movie) documents which have been study sequentially.
