Why do we need computer RAM?
Most modern computers use Random Access Memory for their main memory. However you don't need Random Access Memory, Sequential Access Memory is perfectly adequate and has been used in many computers in the past for main memory (it just happens to be much slower to access than Random Access Memory as you need to wait for the location to come around again).
RAM uses static memory or dynamic memory?
Well, it can be either. There is DRAM (Dynamic random access memory) and SRAM (Static random access memory). DRAM is a much more simple and inexpensive type of memory, it only requires one transistor and capacitor per bit where as SRAM requires four transistors. However, SRAM is faster and uses much less power.
How does random access memory affect the performance of your computer?
RAM is the virtual memory of your computer; the more RAM you have, the more programs you can run at one time. However, that is just a brief explanation.
Which memory temporarily holds data and instructions as the CPU processes them?
RAM (Random Access Memory) and SRAM (Static Random Access Memory) are the most commonly used types of memory used to hold instructions. RAM is the familiar chips you see people use to upgrade memory on the machine. SRAM is normally integrated and very expensive but much faster than normal RAM because it communicates directly with the processor.
What is the difference between RAM and sequential memory?
RAM stands for Random Access Memory. Computer memory chips on the mother board are random access. Disks drives are mostly random access, in that the head can shift to the location of the data to be read. The memory is slightly sequential in that the head must wait for the tracks to spin beneath it before it can read them. An example of sequential memory would be a tape drive. The tape must advance or rewind to the next location where data is stored.In a sequential file you must begin reading from the first record and continue reading until you find the data you seek (or until the end). In a random access file you can specify the number or key of the record you wish to read or write. Random access tends to be much faster for this reason.
What does RAM mean in talking about a computer?
RAM stands for Random Access Memory.The term Random Access refers to the fact that the computer can read or write to any specific addresses in any order required. It does not have to be gone through sequentially. This is the memory the computer works with when it is running a program ... as opposed to the storage memory of disk drives. While disk drives are also random access, they are not referred to as such. Disk drives are much slower, so the code the computer is working with is copied into RAM while it is using it, along with any data it might be working with.
Ram stands for what kind of memory?
RAM stands for Random Access Memory. This memory is not like a Flash Drive or Hard Drive, as it is volatile; this means it only temporarily stores data, while it is powered. It is used so that while a computer is running, data which the processor requires rapid access to (e.g. a running program) can be stored and accessed much faster.
What do letters ROM stand for?
RAM stands for Random Access Memory or memory in your computer that can be read and written to by programs. The amount of RAM in a computer has a bearing on how much work it can do in a given amount of time, and how complex a program that can be run. The other type of electronic memory in a computer is called ROM, or Read Only Memory, and is the kind of memory that is programmed permanently at the factory that makes your computer a computer and not a toaster. ROM is fixed and usually a smaller size, RAM is expandable (to a point).
What is random axcess memory?
Pretty much all computer memory is Random Access Memory (note spelling) these days but computer folk who are as ancient as I am can remember a time when there was memory you could only access in a specific order. Imagine, for example, a book with no page numbers. You know the piece of information you want is in there somewhere but you don't know where. Your only option is to start at page one and flick through until you find it. Believe it or not, there used to be computer memory like this. What the memory hardware would do is present each of the values it had stored, in strict sequence, continuously cycling round. If you needed a particular value you had to wait for it to come around again. Random Access Memory was a bit of an innovation. You told the memory hardware the address (think of it as the page number in your book) of the item you wanted and bingo, it came straight out with it. You could access any location in the memory, chosen at random, and the results would come back at the same speed no matter which piece of information you were looking for. This was such an innovation that the computer folks called it "Random Access Memory", often abbreviated to RAM. The term stuck, even though all solid state memory is like this nowadays. Today, Random Access Memory, or RAM, has come to mean any solid state memory or, more specifically, the solid state memory installed in your computer.
Will 1gb of memory make your pc faster?
1 GB of RAM (Random Access Memory) isn't very much. If your computer can support it, it is best to get 4-6 GB RAM for maximum efficiency.
Is Cache memory generally slower than RAM?
Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory. Cache Memory generally comes in smaller size (3MB, 6MB etc) than the RAM (512 MB, 1GB,2GB.....)
What is Random accsess memory?
DRAM or dynamic random access memory is a type of RAM that stores data in separate capacitors, which is a more efficient way compared to static RAM. It is the most common type of memory found in personal computers.
