Also, as most such systems were single-task, sophisticated systems were not required as much. Two types of memory are used by the computer, one for storing data permanently and second for operating. Computer memory is a location in which various data is stored in a computer system. Memory management is the process of controlling and coordinating computer memory, assigning portions called blocks to various running programs to optimize overall system performance. 2. Define Computer Memory. The results of an error like this are unpredictable. Memory is almost always being actively used by your computer. [13] NMOS memory was commercialized by IBM in the early 1970s. Programmable read-only memory (PROM) was invented by Wen Tsing Chow in 1956, while working for the Arma Division of the American Bosch Arma Corporation. This location was a physical location on the actual memory hardware. Computer definition, a programmable electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations. For example, some data can be stored in physical RAM chips while other data is stored on a hard drive (e.g. Memory is best storage part to the computer users to save information, programs and etc, The computer memory offer several kinds of storage media some of them can store data temporarily and some them can store permanently. [18] MOS technology is the basis for modern DRAM. The same year, the concept of solid-state memory on an integrated circuit (IC) chip was proposed by applications engineer Bob Norman at Fairchild Semiconductor. Memory is internal storage areas in the computer system. Computer memory operates at a high speed, for example random-access memory (RAM), as a distinction from stor… If your system is slow or unresponsive, you may need a memory upgrade. Additional RAM allows a computer to work with more information at the same time, which usually has a considerable effect on total system performance. Using cathode ray tubes, Fred Williams would invent the Williams tube, which would be the first random-access computer memory. 1 Answer +1 vote .
