Computer Memory

The computer memory is a physical device used to store data or programs for use in a computer. Some types of computer memory include RAM (random access memory), ROM (read-only memory), and page cache.

Meaning of the parts of the keyboard?

The meaning behind keyboard parts can regard to subjects. The actual components between the keys, switches and dials are one definition. The other definition depending on context are the number keys, arrows and letter, which indicate keyboard sections.

Is ddr3 ram compatible with Pentium 4?

It depends on the NorthBridge of the motherboard and the socket of the P4. Most intel-processor supported DDR3 Motherboard should be able to run a pentium, but remember that Pentium4 are very slow and DDR3 is still very immature. I recommend you to rather spend more money upgrading your CPU AND MOBO, rather than moving directly to DDR3.

Is there a way to wipe a computer hard-drive without destroying programs or program data?

The 'format' command will appear to erase the hard-drive HOWEVER - ALL it does is erase the reference track. The data will still be on the drive (and can be recovered). There are programs that will physically write either random characters or just zeros to every sector of the drive - over-writing all the data that was stored.

What is the difference between gigga bytes mega byte and tera byte?

1024 megabyte = 1 gigabyte

1024 gigabyte = 1 terabyte

A terabyte is MUCH bigger than a megabyte. Here is a break down of the sizes:

  • Terabyte = 1024 Gigabytes
  • Gigabyte = 1024 Megabytes
  • Megabyte = 1024 Kilobytes
  • Kilobyte = 1024 Bytes
  • Byte = 8 Bits
  • Nibble = 4 Bits

What is the Difference between secondary memory and auxiliary memory?

secondary memory is actually the permanent memory/the backing storage of the computer. it is of two types:

sequential access

direct access

auxiliary memory is the computer's internal/temporary memory. it is also of two types:

random access memory (RAM)

read only memory (ROM)
the difference between secondary memory and auxiliary memory is that:-

both are same i.e both performs the same operations

thanks.

How much MB of ram is in 1 GB of ram?

1 byte = 8 bits

1 kilobyte (kB) = 1024 bytes

1 megabyte (mB) = 1024 kB

1 gigabyte (gB) = 1024 mB

Basically, the 1024 comes from computers using the binary system

What is a after a petabyte?

zettabyte, then yottabyte..

...so says another online source: http://www.chaaban.info/2006/11/02/what-comes-after-the-terabyte/

What is the function of the CD RAM?

The function of a CD to a computer is read only. A CD is used to view information stored on a computer and easily removed to transport to another location like sneaker netting. A CD-R is for reading and recording data that you do not wish to have saved only to the computer.

What are the four types of memory and their functions?

The few types of memory includes sensory memory, which deals with sensory information and stores visuals for few seconds. The other is short-term memory which recalls events or things happened over a perod of few seconds to few minutes, and then we have long term memory which deals with info over a larger period of time.

What are disadvantages of shared memory?

Interesting question. Most agree that shared memory should be minimized and that you should use IPC rather than shared memory if at all possible. Object Oriented programming suggests that an "Object" have it's own methods and that should be the only way that the data object should be modified. Shared memory tends to bypass that construct. In the current programming environment, shared memory is no longer recommended.

What is one billion bytes called?

1,000 bytes, strictly doesn't have a name. A kilobyte is 1,024 bytes.

However, hard drive manufactures round this down to 1,000 bytes, so you can argue that 1,000 bytes is called a kilobyte.

Hard Drives that are advertised as 1TB drives often only have 1,000GB, not the 1,024GB they should have by definition... Always read the label!

Is memory a set of computer programs used ona computer to help perform tasks?

No. Memory is a physical component that temporarily stores on-demand digital data that is either being used by a program or transferred via a network connection to another computer (i.e. Random Access Memory or RAM).

Memory might also refer to the physical component used to store digital data for later access; the hard drive (HDD).

Virtual Memory is still physical memory in that it's a portion of the HDD allocated to assist the RAM in performing operations associated with the transfer of data.

What uses a portion of the hard drive as an extension of your physical ram?

Virtual Memory is using the Hard Drive as if it were RAM.

Cache is memory for frequently used things and is not stored on the hard drive.

Will pc3200 ram replace pc133?

No. DDR RAM cannot be used to replace or upgrade a PC133 module.

Role of rom in computer?

First of All ROM stands for READ ONLY MEMORY the role of ROM in computer is to store all the Information about any computer hardware such as the processor speed, CD-ROM/DVD-ROM drives etc. It is a permenant memory which contains also BIOS (basic input output system) configuration and settings.

Who invented the first ram chip?

The first computer RAM was invented by Freddie Williams and Tom Kilburn in England in 1946 using CRTs similar to those used in laboratory oscilloscopes of the time. The memory was electrostatic and required refresh like modern DRAM. The main difference between their memory and modern DRAM in operation was that addressing and refreshing required analog deflection amplifiers instead of being completely digital.

What type of DIMM supports triple channeling?

DIMM is a type of computer memory for your computer, and it supports certain types of channeling. DIMM 1, 2 3, and 4 supports some types of dual channelling.
