Answer Random access memory (RAM) is memory that can be written to easily (which usually means by the device where the memory's installed). 'Random access' means any part of the memory can be got at immediately. RAM needs to be supplied with power to keep what's in it. ROM (Read Only Memory) doesn't, but writing to it is more difficult - you usually need a separate writer. Random access memory is more commonly said as RAM.
RAM - Random Access Memory. A random-access device allows stored data to be accessed directly in any random order. What is the difference between a port and a.
Random access memory or RAM is what some of the speed of your pc or laptop comes from. RAM Looks like a long chip that goes inside your computer and it comes in gigabytes and most computer have 2 RAM slots so E.G. My laptop has got 4gbs of RAM. It has to 2gb sticks.
There are about 10different RAM stick ones with 200 pins, 204pins, 240pin etc. When the Semiconductor technology not in existence there was a usage of magnetic tapes and magnetic drums which were the Sequential access means If you currently at the position of words which is starts from 'A' so if you need to look up the words started from 'Z' then you've to go through all alphabets means b,c,d.y then you'll get your position at 'Z'. It's similar to Audio or Video cassette.
But the Ram is Random Access means 'The ability of a computer to find and go directly to a particular storage location without having to search sequentially from the beginning location' The human equivalent of random access would be the ability to find a desired address in an address book without having to proceed sequentially through all the addresses. The first random access memory was the Williams-Kilburn Tube (atype of cathode ray tube - CRT) invented by Freddie Williams and Tom Kilburn in 1946 at the University of Manchester inEngland. It was a dynamic random access memory (DRAM) like mostmodern semiconductor random access memory, and like them needed tobe refreshed periodically to prevent loss of data due to thegradual discharge of the capacitances used to store bits.
Unlikemodern semiconductor random access memory, addressing of the memoryused analog waveforms which made the Williams-Kilburn Tubesensitive to drift, temperature changes, power stability, etc. It was very popular on large high speed computers until ferritemagnetic core memory began to replace it after 1954. Magnetic corememory had the advantages of being nonvolatile static random accessmemory (NOVSRAM) meaning it not only needed no refresh but alsoretained data while power was off, as well as having all digitaladdressing.
Computer RAM = Random Access Memory, A component/part of primary memory of a computer system. (Computer) Memory = Every computer system must have 2 kinds of memory. Primary Memory/Storage: (also known as internal memory) Is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them as required.
E.g: RAM, ROM, Processor registers, Processor cache etc. Secondary Memory/storage: (also known as external memory) is not directly accessible by the CPU. The computer usually uses its I/O channels to access secondary storage and transfers the desired data using data buffer (intermediate area) in primary storage. Secondary storage does not lose the data when the device is powered down—it is non-volatile. E.g: HDD, SSD, ODD, USB flash drives or keys, floppy disks, magnetic tape etc. RAM = random access memory; i.e. Volatile memory that loses its contents when power to a computer is turned off.
Memory is a generic term referring to either RAM, ROM (read only memory), or in some cases non-volatile memory such as a hard disk, SSD, USB flash, SD card or other. Non-techies often say they need more memory in their company but what they really mean is they need a larger hard disk. There are many types of RAMs in a computer such as a DRAM, SRAM, etc. The difference typically is the size of the RAM and the proximity of the RAM to the CPU. The closer it is the lower latency it has. L1 SRAM for instance usually can be accessed with a CPU cycle.
DRAM, or dynamic RAM is usually very large but further from the CPU. It can take 100s of CPU cycles to access the DRAM. Non-volatile memory tends to be the largest, but slowest to access. The benefit is that it is large, so can be used for page swapping when the system runs out of DRAM during runtime execution of programs, and it can be used to store data after power is turned off.
