the two main types of RAM are: SRAM- static random access memory which is faster but more expensive it also takes up valuable space. It tends to be used for cache memory and it doesnt have to be periocically refreshed. DRAM- dynamic random access memory, the most common type of RAM, an advantage of DRAM is its structural simplicity.

The two types of primary memory are?
Volatile memory refers to RAM that needs to be constantly refreshed to be retained. Static memory is permanent storage that is retained even after the computer is turned off.
What are the main differences between ROM and RAM?
RAM is random access memory which can be written to and read. ROM is read only memory which is programmed to do a specific job, it can not be edited after it has been burnt ROM-- When viewing on a computer, Read Only Memory is information you can read and cannot click or cannot make it operable. It is not accessible. RAM--When viewing on a computer, Random Access Memory is information you can access and you can click and you can make it operable. It is accessible.
What is computer RAM for?
A computer has two types of memory, RAM or random access memory and ROM or read only memory. With read only memory, the computer can read the memory but can not change it. It tells the computer how to work. Random access memory is memory that can be changed. It tells your computer what to do. Once you are finished with the random access memory, you can use the space it occupied for other tasks. The two are analogous to the way your body works. You have both kinds. If you tell your hand to pick up a pencil, you are using random access memory. You are telling your hand to do one of many possible different instructions. You do not need to tell your hand which tendons, muscles, veins, arteries, nerves, and bones to use in the process. Those instructions are built in. That is analogous to read only memory. Soon after you picked up your pencil, you have forgotten you picked it up. You have started to draw a picture or add some numbers. You are using your short term memory for something else. It does not matter what. Soon you will forget that also. You will forget the start of a project. You will remember the finished product. You may save that. You can not save that in random access memory but you can save your drawing or math homework.
What does a ram do for a computer?
RAM stores frequently used data from the hard disk. This is necessary as the hard disk is many times slower than RAM, which means it will take much more longer for the computer to read the data.
What is the meaning of RAM in a computer?
The modern use of the acronym RAM is a computer memory term, Random Access Memory.Random Access Memory (RAM) provides space for your computer to read and write data to be accessed by the CPU (central processing unit). When people refer to a computer's memory they usually mean its RAM. If you add more RAM to your computer, you reduce the number of times your CPU must read data from your hard disk. This usually allows your computer to work considerably faster, as RAM is many times faster than a hard disk. RAM is volatile, so data stored in RAM stays there ONLY as long as your computer is running. As soon as you turn the computer off, any data in the RAM disappears.As one example, if you use your mouse in MS Word to highlight text, and click COPY, the copied data is "held" in RAM memory until you hit PASTE in another document or spot in the original file. That data stays in RAM, until you COPY something else, OR until you turn off the computer.RAM today it takes the form of integrated circuits that allow the stored data to be accessed in any order (i.e., at random). The word random thus refers to the fact that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data. This contrasts with storage mechanisms such as tapes, magnetic discs and optical discs, which rely on the physical movement of the recording medium or a reading head. In these devices, the movement takes longer than the data transfer, and the retrieval time varies depending on the physical location of the next item. The word RAM is mostly associated with volatile types of memory , where the information is lost after the power is switched off. However, many other types of memory are RAM as well , including most types of ROM and a kind of flash memory called NOR-Flash.
What are the different types of memory access?
There are two types of memory access. 1- uniform memory access (uma) 2- non-uniform memory access (numa)
What are the 2 types of memory called in a computer system?
RAM (Random Access Memory) and ROM (Read Only Memory).
What is random only memory?
There is no such thing as "random only memory" The two main types are: RAM: random access memory ROM: read only memory ROM is memory that does not change, it is "read only" the system reads it, uses it and never changes what is stored within it RAM allows random access types, reading, writing, moving. Its fully adaptable to whatever it is asked to do from moment to moment.
How many kind of computer memory?
Types of Memory:- 1.ROM(Read Only Memory) 2.RAM(Random Access Memory)
What types of memory do notebook computers use?
Hard drive, ROM (read-only memory) and RAM (random access memory)
What are the different computer memory types?
The 5 types are: SIMM DIMM SODIMM SORIMM RDRAM The basic types are volatile memory such as RAM memory and 'permanent' memory such as hard drives USB, external drives and CD/DVDs
What are the two main types of computer chips?
ROM (Read only Memory) and RAM (Random access memory). However, there are loads more types of computer memory than these two.
The two types of primary memory are?
Volatile memory refers to RAM that needs to be constantly refreshed to be retained. Static memory is permanent storage that is retained even after the computer is turned off.
Write short notes on different types of RAM?
Basically main memory is referred as Random Access Memory (RAM) because it is possible to randomly select and use any location of this memory to direct store and retrieve data and instructions.
How is cache different from primary memory?
Cache memory is a memory that is used by CPU so that the average time to access the memory is reduced. It is a smaller and faster memory that stores copies of data which is used in frequently accessed main memory locations, On the other hand, Primary memory is the main memory of the computer. The processor can easily access, store and retrieve information from the primary memory. Primary memory has two types, Random access memory and read only memory.
What do you mean by ram?
Random Access Memory, it is called main memory because processor only access data from RAM. Various types of RAM in market today, such as DDR, DDR2, DDR3. Different motherboard supports different RAM, but before purchase it you must choose maximum size and speed of RAM if your motherboard support.
RAM is divided into what two categories?
There are two different types of RAM: DRAM (Dynamic Random Access Memory) and SRAM (Static Random Access Memory). DRAM is more common. It needs to be refreshed about 1,000 times per second. It also supports access times of about 60 nanoseconds. SRAM is more expensive. It does not need to refresh so it is faster than DRAM. It supports access times as low as 10 nanoseconds.
