Today we learned about motherboard ,cpu , memory and hard drive.
the motherboard is what you plug every other component of the pc in it.
THe cpu is like the brain which does the calculations. Mr. Case showed us some and were made of gold , okay not really. The lead makers are Amd and Intel . Early computers had even less than 100 mhz and today 3.2 ghz processor isn't too uncommon. A new technology called dual core lets the processor do 2 different sets of instructions at once.
THe hard drive is used for storage like saving your documents , music and OS. It is allways there like a bookshelf. Early computers had a huge hard drive that could hold like a around 80 megabytes (around 10% of a Cd )compared to today's technology that easily holds 100 gigabytes.
Memory is a little trickier it holds information but only what you do then . E.g :the Hard Drive is the library and your memory is a table on which you read your material.And i guess your brain is the cpu and the whole room is the motherboard on which you put the stuff in.
Mr Case showed some old technology and it it remarkable how much these components evolved in size and performance also.
