Read only memory (ROM) is the permanent memory which is used to store these important control programs and systems software to perform functions such as booting up or starting up programs. Memory is the imaginative reconstruction of our attitudes and past reactions with bits of actual fact added to the mix. Human Memory – Facts. Most short-term memories are, well, short-term. Just like we all have a memory, our computer also have its own memory. ROM is non-volatile. Unlike RAM, it keeps its contents even when the computer or device is turned off. Experts believe that you can hold approximately seven items in short-term memory for about 20 to 30 seconds. To try to avoid this confusion the International Electrotechnical Commission (IEC) use the names kibibyte, mebibyte, and gibibyte for binary powers. 15. In most cases, RAM is included as a volatile type of memory. If a computer had to support the same memory bank, it would need a nuclear power station. , cherran, No Comment, June 25, 2016 Let us find out about a few interesting computer facts, and get ourselves amazed.
