please explain the function of ram in computers?

Answer 1

Random-access memory (RAM) is a form of computer data storage. A random-access device allows stored data to be accessed in very nearly the same amount of time for any storage location, so data can be accessed quickly in any random order. In contrast, other data storage media such as hard disks, CDs, DVDs and magnetic tape, as well as early primary memory types such as drum memory, read and write data only in a predetermined order, consecutively, because of mechanical design limitations. Therefore the time to access a given data location varies significantly depending on its physical location. Today, random-access memory takes the form of integrated circuits. Strictly speaking, modern types of DRAM are not random access, as data is read in bursts, although the name DRAM / RAM has stuck. However, many types of SRAM, ROM, OTP, and NOR flash are still random access even in a strict sense. RAM is often associated with volatile types of memory (such as DRAM memory modules), where its stored information is lost if the power is removed. Many other types of non-volatile memory are RAM as well, including most types of ROM and a type of flash memory called NOR-Flash. The first RAM modules to come into the market were created in 1951 and were sold until the late 1960s and early 1970s.

Answer 2

RAM is a data storage from which information can be retrieved in any order. Information is stored at different address location across RAM and it always takes the same amount of time to access the data from any location. That means data/ information is fetched randomly which does not change the access time.



It is done basically using integrated circuits / digital logic.



RAM is generally volatile memory which gets erased when power is turned off.

Answer 3

RAM (Randam Access Memory)

its run your programes when you used to work on.

Answer 4

RAM is shortened from RANDOM ACCESS MEMORY. This type of memory is not like the memory on your hard drive which is put on your hard drive and stays there until you delete it. This memory is just used for working programs and does not stay there when you turn the computer off.



RAM is used for current programs. Just think if you had every possible action in every program on your computer, it would take ages to load. So RAM is used to keep the information of the actions you are doing at the moment. Like listening to music and surfing the web.

Answer 5

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.



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.­

This refresh operation is where dynamic RAM gets its name. Dynamic RAM has to be dynamically refreshed all of the time or it forgets what it is holding. The downside of all of this refreshing is that it takes time and slows down the memory.

Answer 6

Its where the computer remembers what its doing during the most recent moments. Aka, if you're looking at a picture that is stored somewhere on your computer, the computer will place it in ram, so that it can be more easily accessable. ever notice how when you're flipping through your photos, once you actually look at a picture it loads more quickly if you flip back to it?

Answer 7

its tempoary memory your computer uses to run programs

Answer 8

RAM is where all application are executed by the processor. When you open an application or a game, it is copied from the harddrive to RAM and executed there. Why? because RAM is lot faster than the hard drive. while executing an application processor needs to write or read data from the application. So, the more RAM you have, the faster your computer will perform.

Answer 9

i c others have explained the ans of u r question very well!!

i dont need 2 write much!!



but the basic is jst that if u r brain is the cpu den u r work place(where ever u do the work u do) is the RAM!!
