Indefinitely, as long as power is not removed from the system. Once power is removed, all address locations in RAM revert to their default state.

How do you test a random access memory?
On the inside of your tower there is a one inch tall by four inch long chip ripe thing attached to ur motherboard. That is your ram or random access memory.
How many types of RAM are there?
Dynamic Random Access Memory(DRAM):-contents are constantly refreshed 100times per second.Access time 60-70 nanoseconds.Synchronous dynamic random access memory(SDRAM):- quicker than DRAMaccess time than 60 nanoseconds.Direct rambus Dynamic Random Access Memory(DRDRAM):- new type of ram architecture.access time is 20 times faster than DRAM.more expensive.Static random access memory(SRAM):- doesn't need refreshing.retains contents as long as power applied to the chip.access time is around 10 nanoseconds.used for cache memory, CPU registers.CMOS SRAM also data and time settings, powered by small battery.Cache memory:- small amount of memory typically 256 kilobytes to 32 megabytes (depending on computer).temporary storage for often used instructions and datacpu checks to see whether the next instructions it requires in cache.if not the cpu has to fetch next information from the main memory.Often implemented in multiple levels: L1I/L1D, L2, L3, etc.Video random access memory:- holds the data that can be displayed on the computer.Has two data paths allowing to READ & WRITE to occur at same timea graphics card may have its own VRAM chip on board.Flash Memory:- contents are retained even without powerread cycles are similar to SRAMunfortunately write cycles are about 100 times slower than read cyclesdue to this read/write timing asymmetry, these are more commonly used as "solid state disks" like Compact Flash, SD cards, "USB pen drives", etc. than as normal computer memoryNonvolatile Random Access Memory(NOVRAM):- contents are retained even without powerimplemented as and SRAM with Flash Memory backup storageat power on, internal circuits copy the Flash Memory to the SRAM all bits at the same time in one cyclewhile power is on the SRAM is accessed as normalwhen a signal is received from the powersupply warning that power is turning off, internal circuits copy the SRAM to the Flash Memory all bits at the same time, however as the Flash Memory write time is much longer than its read time this powersupply warning signal must significantly precede actual loss of power at the NOVRAM chip.Ferrite magnetic core memory: contents are retained even without powerhas been considered obsolete since about 1980even with automated machine assembly these still required significant hand labor to buildFerromagnetic Random Access Memory(FRAM):- contents are retained even without powerIntegrated circuits intended to replace DRAM are still in development
Why is Mayan corn stored in chultunes?
It was easy to preserve food such as corn for long a long period of time
Who said that the shortest pencil is better than a long memory?

How long has Utah been a state in the USA?
On January 4, 1896, Utah became the 45th state. The new government officially started two days later on January 6, 1896.
What is the long form of RAM?
random access memory
RAM and ROM are both forms of random access memory True or False?
True.Although RAM is an acronym for Random Access Memory, both RAM and ROM are in fact examples of random access memory. That is because random access memory is memory that can be read or written in any arbitrary order, as long as you address the correct unit of memory. By contrast, sequential access memory, such as a tape, must be accessed in sequence - you must read or write through, or mechanically position, the tape until you reach the unit of memory you wish to access.In computers, RAM is typically (but not always) both volatile and read/writeable. ROM is typically (but not always) read-only and non-volatile. Volatile means the stored information is lost when the computer is shut off, non-volatile means the stored information persists, usually indefinitely, even after the computer has been turned off.
Is RAM something referred to as involatile memory?
RAM stands for Random Access Memory. It does not specify whether it is volatile or non-volatile. RAM is just an access method just like SAM (serial access memory eg. magnetic tapes). The memory you are talking about is called primary memory of the computer which is semiconductor memory. Data can be stored in it as long as it is powered on since data is stored in the form of electric charge. Even Hard disks are RAM because you can randomly access any data from anywhere in the HDD
How do you test a random access memory?

What RAM stand for in computers?
RAM is Random Access Memory. They're designed to be fast and temporary, ideal for storing programs and data that the computer is currently working on. Once the power is off, the contents of RAM will be erased.
What does RAM for a computer mean?
RAM = Random access memory. It is a volatile (loses all data stored when the computer is turned off) yet fast data storage device used in computers. Reading/writing to the harddrive takes a long time, due to moving parts, so the RAM acts as a go between to 'speed up' calculations.
Opposite to Random access memory?
Sequential access memory. Typically implemented with long shift registers, acoustic delay lines, or fixed head magnetic drums/disks.
Are the memory chips and the hard drive the same thing?
No, the memory chips are RAM, Random Access Memory. These are actual chips that fit into slots on the motherboard. This type of memory is temporary memory that your computer uses for current operations. This can be compared to active consciousness. This is what you're aware of at that moment, what's currently happening. The hard drive is memory storage. This is long-term memory. Data can be retrieved from here & brought into RAM, & data can be stored here from RAM. But this is long term memory, and is stored on a disk drive separate from but connected to the motherboard.
What is 2 type of memory?
For Human Memory:1)Short-term2)Long Term3) SensoryFor Computers(Internal Memory):1)Random Access Memory2)Hard Disk Drive
What memory stored in the hard drive?
Hard-drives are not memory as such, they are storage devices. However, the contents of RAM (Random Access Memory) are stored on the hard drive in the form of one or more paging files, allowing the operating system to realise more RAM than physically exists (virtual memory). The contents of RAM are also stored on the hard drive when the computer enters hibernation mode. Aside from that, hard-drives provide long-term storage of programs and files that can be loaded into memory as and when required.
What is read only memory?
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.
What is stored in central processing unit of a computer?
Very little is stored in it - mostly, that's the job of RAM (read-only memory) for short-term storage or the hard drive or other more permanent medium. CPUs do have relatively small registers that store numbers for long enough to work on them. However, the main job of the CPU is number crunching.
