Core memory refers to computer memory that consisted of magnetic cores. This memory is now obsolete and is replaced by semiconductor memory known as main memory.
what is a semiconductor material? what are its main types, explain each type
RAM or Random Access Memory is Tempory memory which your computer uses to load programs such as windows or games Your Hard Drive is an example of permanent memory on your computer where you can save documents/games etc. So when you load up your PC the computer reads the HD and loads up your OS (eg Windows) into your RAM.
Computer memory
# Main memory is the short term memory of a computer. It retains data only for the period that a program is running, and that's it.
Main memory in a computer is storage that will be erased when a computer is turned off. Backing storage is memory that will save information when the computer shuts down.
yes.. it losses data as you turn off your computer..
Optical memory is an early form of computer memory. It involves the use of an optical system for the writing and reading of data to and from a computer's main memory.
Ans. Read Only Memory (ROM):Another important part of main memory is Read Only Memory (ROM). Instructions can only be read from ROM. Instructions once written on ROM chip cannot be changed. It is a permanent or non-volatile memory of a computer, i.e. the contents of this type of memory are not lost when the computer is turned off. As soon as the computer is turned on, a program that resides in ROM automatically makes the computer ready for use. ROM is a semiconductor memory generally programmed by the manufacturer.Difference between PROM and EPROM:(Programmable Read Only Memory):It is a non-permanent memory of a computer. It is programmeable read only memory.EPROM (Erasable and programmable Read Only Memory):It is a non-permanent memory of a computer. It is programmeable and erase able read only memory.
primary memory is built in memory on a computer it is the main type of memory.... eg RAM ROM and HDD
yes
The Mother Board!
