What is a random access memory?

Question

I WANNA KNOW TECHNICALLY ABOUT RANDOM ACCESS MEMORY

Answer 1

Random access memory (usually known by its acronym, RAM) is a type of data store used in computers that allows 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.

It costs practically the same time to access any piece of data stored in a RAM chip. In contrast, disks and the like need a short time to retrieve a piece of data if it happens to be close to the current position of the read head, and a long time if the data is far away and the head needs to be repositioned considerably.

Generally, RAM in a computer is considered main memory or primary storage: the working area used for loading, displaying and manipulating applications and data. This type of RAM is usually in the form of integrated circuits (ICs). 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 chewing gum. Most personal computers have slots for adding and replacing memory sticks.

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 ROM, but in a more true sense, of sequential access memory.

Answer 2

how technical? Random Access Memory is you buffer. it stores all of your most accessed programs and files for when you use them. Bassically there are 4 levels of storage in the modern day computer the L1, L2 cache, the RAM, and finally the Hard Drive. when you open a program the processor looks for the files it will start in the fastest area the L1 cache if it can not find it in there it goes on to the next one the L2 and then if the computer supports the L3 cache. After all of this(which only takes a tenth of a nanosecond) it begins searching the RAM. if it cannot find what it is looking for it moves on the the Hard drive which is slower than the ram by at least a factor of 10.

Answer 3

RANDOM ACCESS MEMORY(RAM) is temporary storage for the stuff needed to run programs. Once power is turned off all data on the ram is erased.

Answer 4

what every 1 else said but all you really have to do is take the RAM stick to the guy that sells PC parts he should be able to give you one just like it, its pretty basic just compare the one u have with the new 1 if they look the same where the pins are have the same opening then it will fit in your pc, to check if it worked is also simple if it worked your computer will start if it didnt it wont also if you want to know exactly how much RAM you have its also really simple just right click on my pc icon and click properties it will tell you your procesor, ram and a few other details

Answer 5

RAM is the immediate memory stored in your computer to acces programs faster. Instead of your computer haveing to look all over your hardrive. It can acess the ram and find the program faster. Therefore the more RAM you have the faster your computer can open a program because it doesnt have to look far for it.

Answer 6

it is an electronic memory device which is inserted in computer . it is very important componant in computer . the computer will not work with out this chip.
it had lot of models dram, sram, etc. it works very fast. it plays key role in computers fastness. it is also called as RAM. some rams built with transistors and some rams built with semiconductors and some built with IC's. it depends on the model.

Answer 7

random access memory is how your computer runs programs. it determines how many programs it can run at one time....and it could make your computer faster or slower. if you have alot of memory...you will be able to run more programs at one time without your computer freezing up.

Answer 8

Here is an easy read -

hard drive - your file cabinet
.....larger the hard drive - more files to store
RAM - your dining room table
...the more RAM - the larger number of files that can be open at one time
cache - how fast you can get your files from the hard drive to the RAM to see on your monitor (dining room table)

Answer 9

just for your understanding , i am saying this

consider...
processor is the BATSMAN
applications are BOWLERS
conditions are fielders

and the game played in a GROUND -- thats RAM

without ram nothing works...
