Conclusion

* Approximately 1 million bytes. All computers have memory to store instructions and data. There are two main of memory. * RAM (random access memory) * ROM (read only memory). Random access memory (RAM) The typical amount of RAM in a microcomputer might be 128 megabytes. When the computer is switched off, this memory is empty. As the computer is started, operating instruction, computer programs and data are moved into this memory as required. ...read more.
