Random Access Memory (RAM)
Depending on the architecture of the computer one addressable memory location might be called a word, a character, a parcel, a decimal digit, a byte, etc.
In RAM ,the access time is the same for any memory location.Semi-conductor IC chips and magnetic disks are random access memory.In SAM a particular memory word is accessed from the memory by going through all address locations until the desired address is found.Magnetic tapes are sequential access memory.
Cache is not an abbreviation. Cache comes from the French word caché, meaning "storage" or "hidden place."
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. 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.
The modern use of the acronym RAM is a computer memory term, Random Access Memory.(see related question)The other uses of the word are for a male sheep or goat, or the verb meaning to smash into, and the derived name for a type of ship used to ram other ships.It can also mean a machine used to compress, push, or load, such as a hydraulic ram.
On most modern computers this means 65,536 bytes (8 bits) of random access memory, which can be both read and written.On older computers this could mean a variety of different things depending on the architecture of the specific computer, some are:65,536 words of random access memory, which can be both read and written. A word could be any number of bits in length, with values from 12 bits to 60 bits being most common. No entity smaller than a full word is directly addressable on these machines.64,000 words of random access memory, which can be both read and written. A word could be any number of decimal digits in length, with values from 5 decimal digits to 12 decimal digits being most common. No entity smaller than a full word is directly addressable on these machines.65,536 characters of random access memory, which can be both read and written. A character was typically 6 bits in length.64,000 characters of random access memory, which can be both read and written. A character was typically 6 bits in length.65,536 bits of random access memory, which can be both read and written. Any individual bit or group of bits (of any length up to 65,536 bits) is directly addressable on these machines.etc.One really needs to be more specific with units to be unambiguous.
RAM Memory is "Random Access Memory", meaning that any word of memory can be accessed randomly, in any order; that is, without starting at the beginning and reading the memory like a tape. RAM memory is usually volatile, meaning that its contents are lost when the power is turned off.
RAM or Random Access Memory is used for fast computer memory. The word "Random" is a bit of a misnomer, as there is nothing random about access to this memory. What it actually means is that you can select an address at "random", that is, any address within the capability of the memory, and read or write data to/from that address just as fast as you could read or write data to any other address. In other words, data stored anywhere in the memory can be accessed quickly. Serial memory is different in that access time depends upon where on the medium the data is stored. Examples are magnetic tape, optical disk, magnetic disk. "arbitary access" is not a term used in electronics that I can find. I think it is just another term for "random access".
Random-access memory (RAM)
Random Access Memory You might be referring to long-term storage (files and such), in which case it would probably be a hard drive or hard disk. In some cases, it would be a Solid State Drive.
Another name for working memory is short-term memory. It refers to the system in the brain responsible for temporarily storing and managing information required to carry out cognitive tasks such as learning, reasoning, and comprehension.
