what is meaning RAM?

Question

That is computer memery

Answer 1

RAM is Random Access Memory. Computers use it to run programs, they take information from the hard drives (which are much, much slower to access) and save it in RAM (which is pretty quick to access). It then takes the commands from RAM and run it on other data in RAM.

Answer 2

Random access memory (RAM) is the best known form of computer memory. RAM is considered "random access" because you can access any memory cell directly if you know the row and column that intersect at that cell.

What do you think of them?
The opposite of RAM is serial access memory (SAM). SAM stores data as a series of memory cells that can only be accessed sequentially (like a cassette tape). If the data is not in the current location, each memory cell is checked until the needed data is found. SAM works very well for memory buffers, where the data is normally stored in the order in which it will be used (a good example is the texture buffer memory on a video card). RAM data, on the other hand, can be accessed in any order.

Similar to a microprocessor, a memory chip is an integrated circuit (IC) made of millions of transistors and capacitors. In the most common form of computer memory, dynamic random access memory (DRAM), a transistor and a capacitor are paired to create a memory cell, which represents a single bit of data. The capacitor holds the bit of information -- a 0 or a 1 (see How Bits and Bytes Work for information on bits). The transistor acts as a switch that lets the control circuitry on the memory chip read the capacitor or change its state.

A capacitor is like a small bucket that is able to store electrons. To store a 1 in the memory cell, the bucket is filled with electrons. To store a 0, it is emptied. The problem with the capacitor's bucket is that it has a leak. In a matter of a few milliseconds a full bucket becomes empty. Therefore, for dynamic memory to work, either the CPU or the memory controller has to come along and recharge all of the capacitors holding a 1 before they discharge. To do this, the memory controller reads the memory and then writes it right back. This refresh operation happens automatically thousands of times per second.

Random Access Memory. Random Access means that the computer is able to address the memory so it can find any part of the memory it needs. The computer can also change the content of the memory. This is the type of memory used when you are running programs on your PC. The computer is able to change information in the memory (so you can load programs and change data files) and to access different parts of the memory as needed (goes to one location to find the next command in the program and another location to find the data file being worked on). RAM memory is temporary. When you turn off your computer everything in RAM memory is gone. That's why you have to save your files to your hard drive, which is permanent storage.

The other major memory type is ROM, Read Only Memory. ROM memory is permanent, and can not be changed. It is used for things like the instructions your computer needs to boot before it accesses RAM memory or the hard drive. ROM memory does not clear when you turn off the PC, so the boot instructions will still be available next time you turn on the PC.

Answer 6

RAM means - Random Acesses Memory
there are 2 types
Dynamic RAM (DDR-RAM)
Static RAM (SD-RAM)
Ram can Only store data tempervory only.It is fast to Acesses.

Whan the Power goes OFF, all the information in the RAM is cleared.

Answer 7

Pronounced ramm, acronym for random access memory,
a type of computer memory that can be accessed randomly; that is, any byte of memory can be accessed without touching the preceding bytes. RAM is the most common type of memory found in computers and other devices, such as printers.
There are two basic types of RAM:

dynamic RAM (DRAM)
static RAM (SRAM)
The two types differ in the technology they use to hold data, dynamic RAM being the more common type. Dynamic RAM needs to be refreshed thousands of times per second. Static RAM does not need to be refreshed, which makes it faster; but it is also more expensive than dynamic RAM. Both types of RAM are volatile, meaning that they lose their contents when the power is turned off.

In common usage, the term RAM is synonymous with main memory, the memory available to programs. For example, a computer with 8M RAM has approximately 8 million bytes of memory that programs can use. In contrast, ROM (read-only memory) refers to special memory used to store programs that boot the computer and perform diagnostics. Most personal computers have a small amount of ROM (a few thousand bytes). In fact, both types of memory (ROM and RAM) allow random access. To be precise, therefore, RAM should be referred to as read/write RAM and ROM as read-only RAM.

Answer 8

Random access memeory.

Random-access memory (usually known by its acronym, RAM) refers to data storage formats and equipment that allow the stored data to be accessed in any order — that is, at random, not just in sequence. In contrast, other types of memory devices (such as magnetic tapes, disks, and drums) can access data on the storage medium only in a predetermined order due to constraints in their mechanical design.

Generally, RAM in a computer is considered main memory (or primary storage): the working area used for displaying and manipulating data. This type of RAM is usually in the form of integrated circuits (IC). These are commonly called memory sticks or RAM sticks because they are manufactured as small circuit boards with plastic packaging and are about the size of a few sticks of gum. Most personal computers have slots for adding and replacing memory chips.

RAM is typically erased when a computer is shut down, though some RAM chips maintain data indefinitely without electrical power. Technically, RAM devices are not limited to memory chips, and random-access memory as a storage format is not limited to use as working memory. In a broad sense, modern storage devices for long-term or secondary storage, including magnetic media and laser-readable CDs and DVDs, are forms of random-access memory.

Look up RAM, random access memory in Wiktionary, the free dictionary.Most RAM can be both written to and read from, so "RAM" is often used interchangeably with "read-write memory." In this sense, RAM is the opposite of read-only memory (ROM). Strictly speaking, however, "RAM" and "ROM" are not mutually exclusive designations because "RAM" refers only to the method of accessing stored data, not whether data can be written.

Answer 9

RAM is an acronym for Random Access Memory. It is solid state memory that holds information using electricity to charge capacitors on or off as opposed to a hard drive, which uses magnetic disk to hold information.

Answer 10

Random Access Memory- which is user input; as opposed to ROM- Read Only Memory- which is installed and unable to be altered
