2.Computer elements
2.2Memory and units of storage
computers main memory is it,s RAM [random access memory]
when we run a aplication its instrutions and data are copied too this memory.
RAM cannot work at the same speed as microprocessor . t The cache memory stores the data and the microprocessor.
ROM BIOS is a espetial readonly memory.If everything is ok BIOS start the opeteiting system.
data stores data temporaily when you turn of the computer this data dissapears
2.3 Motherboard and connecting devices
the motherboard is a large boar found in the inside of the computer.The modernboard also includes the folowing componets:
The IDE or ATA and SATA
the chipset is a number of intergrated circuits desaigned to preform relateed funcions.
slots can be used to expande or add new components. They can be PCI or PCI express
various inputs, output
2.1 Microprocessor
Computer history is very closly Iinked to the development of integrated circuits or chips
the microprocessors is an intergrated circuit made of millions of transistors working together.

1.1. Computer functions
Software programs refer too the data and the instructions we use too manage the data
Cnrnputers carry a lot of different functions.
