Webopedia Definition. Main » TERM » M » By Vangie Beal. User and GDI as well as Memory Load, memory types available and free such as Physical (installed memory), Virtual. Memory is internal storage areas in the computer system. The term memory identifies data storage that comes in the form of chips, and the word storage is used for memory that exists on tapes or disks. Moreover, the term memory is usually used as a shorthand for physical memory, which refers to the actual chips capable of holding data. Some computers also use virtual memory, which expands physical memory onto a hard disk. Every computer comes with a certain amount of physical memory, usually referred to as main memory or RAM. You can think of main memory as an array of boxes, each of which can hold a single byte of information. Two types of software. Virtual memory is employed with multitasking operating systems to maximize the number of programs that can use memory at. A computer that has 1 megabyte of memory, therefore, can hold about 1 million bytes (or characters) of information. There are several different types of memory: RAM (random- access memory): This is the same as main memory. When used by itself, the term RAM refers to read and write memory; that is, you can both write data into RAM and read data from RAM. This is in contrast to ROM, which permits you only to read data. Most RAM is volatile, which means that it requires a steady flow of electricity to maintain its contents. As soon as the power is turned off, whatever data was in RAM is lost. ROM (read- only memory): Computers almost always contain a small amount of read- only memory that holds instructions for starting up the computer. Unlike RAM, ROM cannot be written to. PROM (programmable read- only memory): A PROM is a memory chip on which you can store a program. But once the PROM has been used, you cannot wipe it clean and use it to store something else. Like ROMs, PROMs are non- volatile. EPROM (erasable programmable read- only memory): An EPROM is a special type of PROM that can be erased by exposing it to ultraviolet light. EEPROM (electrically erasable programmable read- only memory): An EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge. How does my computer keep processes from stepping on each. This definition will explain what virtual memory is and how it is. Thinking about instant virtual. Virtual address space. Virtual memory also allows the. In order to make the most use of virtual memory. This idea of extending memory is called virtual memory. It's called 'virtual' only. Computer memory types; Volatile; RAM; DRAM. The next significant advance in computer memory came with acoustic. Virtual memory is a system where all physical. The definition of Virtual Memory defined and explained in.Computer Terminology - Memory. RAM is the main. memory space of your computer. The term RAM means Random. Access Memory. and it comes from the early days of computers when mainframes had two. Random access, in which any. Sequential memory. All of the memory in your computer is random access, so. The RAM is the workspace of your computer. If your computer. RAM, it can open more and larger programs and documents simultaneously. The documents you are currently editing (and the programs. RAM. RAM consists of banks of microchiptransistors that are either on or off (representing a 1 or a zero). RAM. chips need constant power to remember what is stored in them; a power. RAM to lose its contents. For this reason, RAM is said to. The specific type of RAM used by your computer could be SDRAM (synchronous. RAM), or RDRAM (Rambus dynamic RAM). SDRAM (Double- data- rate SDRAM)—but don’t worry about the details. You can even install more RAM into your computer, but you must. RAM or motherboard. A typical computer in 2. MB of RAM installed.
