Since the CPU can handle few data at a time, it stores the rest program and data temporarily until it can process them into the RAM. RAM(random access memory) is the most common type of computer memory. It is divided in equal-sized memory locations, which have different addressess so they can be distinguished.
Information in the RAM is an electrical current flowing through silicon chips, so if there is no power the computer erases all information in it. ROM (read-only memory)-memory from which the CPU can read information, but not store more. Computers, calculators, microwave ovens, printers, etc. use it.
Other type of memories:
CMOS(complementary metal-oxide semiconductor) similar to a RAM but stores less data like date, time, and calendar. It is called parameter RAM in macs.
Flash memory: also similar to a RAM but can still work without power. Many handheld devices use it.
Access time: time it takes for a processor to retrieve data from memory, it is mesures in nanoseconds. Hard disk access time is measured in milliseconds.

how memory works
-The CPU memory is divided into:
-Process
- RAM- a lot; writes info into it; info is deleted when shut down
- ROM- few of them; reads info from it; info permanent
-Process
buses parts and peripherals
BUSES
- Connect storage devices in bays: open areas in the system box for drives and other devices.
- a bridge between the processor and RAM
- Connect expansion slots inside the computer’s housing: expansion cads-special purpose circuit boards
- Groups of wires by which information travels between components on the motherboard
PERIPHERALS -keyboard -printers -other machines PORTS -video ports -USB ports -audio ports |

tomorrows computer
It will have a smaller, but faster processor.
Today we have nanotechnology, that approaches the molecular level; this technology makes it a lot faster
Scientists belief that the carbon-based processors will work better because it will used less energy for example graphene. This could have been the stepping stone for quantum computers.
There are other computer that can work for example the optical computer or photonic computer uses light waves using the electrons and photons rather than electrical impulses, like the superconductor computers.
