Thread: What is logical memory in machine refers to.

I had heard several times a logical memory in a system. I found it a bit difficult to understand. The things I got to know is that something related to system RAM and worked right away, are defined in the same conditions. How it works. I need some basic knowledge of working on a ram in a system. I know that the more RAM is the highest runs in your system speed and performance. As a person learning is based out of my mind. Can anyone explain to me the same thing on a very simple way.

Current processes are stored in a memory. The more you have several processes simultaneously. 2 GB is sufficient in most cases. Whatever you use, these processes are stored in RAM and initiates smooth performance of your system. I do not think a lot, but I understand that a memory allows the system to temporarily store the data on the stick and perform various actions. You can add up more to increase your performance and give better performance.

What I have found that there are two types of memory architecture principles. The first is the Neumann architecture and Harvard. The main memory is known as Neumann program memory, which stores the data. The administration is fully compatible with the processor in this area and has no control over stored data. Some viruses can exploit and destroy the RAM, to some extent. In this process, the program is loaded into memory and executed.

There are two types of memory, where the first is a shared memory, which are known as DRAM. And 'cheap. They are primarily used in the computer's main memory. Other is a static RAM which is also known as SRAM. This type of RAM is fast and expensive. SRAM is used in particular, the processor cache. RAM is made up of hundreds of thousands of small capacitors store charges. Once loaded, the logical state of the capacitor is 1, otherwise it is 0, that is, each capacitor represents a bit 'of memory.

Each memory cell is qualified by an address representing to a line number and column number. This access is not instant and takes place in a period recognize as latency. Hence, access to information in the memory lasts a time equal to the cycle of including latency. Thus, for a DRAM-type memory, the access time of 60 nanoseconds. a machine, cycle time is the opposites of the clock frequence, such as a computer running at 200 MHz, the cycle time is 5.
