What is computer memory card?

Answer 1

memory segmentation is the process of dividing the computer memory into different overlapping segments.

Answer 2

Computer memory is used for storing your files on the computer. Without computer memory, you would't be able to save any files, just like playing a video game on PS2 without having a memory card. You would always have to keep it on. It's best to have some memory to store your files.

AnswerIn the computer world, "memory" is generally used in reference to RAM. RAM stands for "Random Access Memory". It is the location in which the computer places all of its active data. The term 'random access' means you can access anything on the memory without having to go through the whole thing, like in a magnetic tape in which access to data is sequential.

A common real-world correlation would be your filing cabinet and desktop at work. When you need to view or edit a file, you take it from your filing cabinet, and put it on your desktop while you work with it. When you're done, the file goes back into the filing cabinet. For computers, the hard drive (sometimes called the "C drive") is the computer's filing cabinet, and RAM is its desktop.

RAM falls under the classification of "volatile memory", which means that once the computer loses power, everything stored in RAM is lost. This means that, if you have made changes to a document without saving it, and you lose power to your computer, whatever changes were made to the document will be lost. This is why it is important to save documents periodically as you're working on them.

RAM is also sometimes called the "poor man's upgrade". Adding RAM to a computer typically speeds up the performance of the machine, and is generally the cheapest upgrade that can be purchased in today's market.

Or in simpler terms, computer memory is a kind of memory found in a computer, which is used for storing downloaded, encoded or such information.

Answer 3

Computer memory refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time. Computer memory provides one of the core functions of the modern computer, that of information retention. It is one of the fundamental components of all modern computers, and coupled with a central processing unit (CPU, a processor), implements the basic computer model used since the 1940s.

Answer 4

High speed memory now has different definitions based

on the specification that the system accesses it. The dominant

spec is "DDR" an acronym for "Double data rate" - there are

two standard specs for DDR memory (which is commonly called

RAM - Random Access Memory - it's an electronic circuit that

stores information in the computer as long as there is electricity

running to it - when you turn the computer off, whatever is in

RAM is lost. There is another type of RAM called NVRAM which

stands for Non-Volatile Random Access Memory - meaning that

it does NOT lose the data stored in it when power is lost/turned-off):

DDR2 and DDR3 - withing these two specs are some "sub specs" based

on how much data the RAM can transfer in and out e.g. DDR2-800

meaning it can transfer 800 megabytes per second at its theoretical

maximum.

Answer 5

It is a small printed circuit board containing several random-access memory chips.
