What is and how it looks?
Memory is one of the most important components of a computer. Memory is volatile meaning when closing the computer or reset it the computer lose all data from memory. We can find in the computer in DIMM slots on the motherboard and integrated circuit are thin and have about 14-15 cm long, 2 inches wide and several mm thick.
Classification
Depending on the usability, memory usage is divided into several groups:
- Memory ROM (Read Only Memory) memory is generally accessed only at startup and stores information related to components of computer architecture;
- RAM - (Random Access Memory), computer memory is used throughout the processing of information;
- Memory VRAM - (Video RAM), memory used by video cards to process. These statements are faster than RAM and are used for the graphics, textures and all that means posting on screen.
- Cache or buffer memory is a memory that this day is incorporated into the processor. This is a much faster memory even than physical memory of the computer.
- Memory or flash memory sticks are portable nonvolatile memory. These statements are used to transport data between computers.
- Memories on card or memory cards, are memories used by cameras, video-cameras, phones and other devices that require data storage on an external support. The reason for choosing this type of card is that it allows flexibility to change it with other cards, without worrying by limitation in terms of file storage.
RAM
Beginners are often confusing memory and storage space, so I will define here both names.
Memory is made up of small modules with integrated circuits which enter slots allowing others to change their higher capacities. Memory is designed to keep all the information the computer needs during its use. Like I said earlier it is not unlimited.
Hard disk is that part of computer that stores information from the files of operating systems to music, movies, games, documents, etc.. Hard disk is designed only to maintain the data not being processed. However when exhaustion RAM memory, the system can use a virtual memory on the hard drive to replace the lack of memory and does jammed the PC making it being unusable. It may seem the computer that has unlimited memory but there is no memory and you can seen when the speed slows and the computer works in a dramatic way. The purpose of virtual memory is for processing physical memory is not enough. Note: not all slow down, means that the systems memory failure but nevertheless is not subject to this chapter, so I will not enter here in more detail.
RAM can attend class after frequency and after latency.
Latency is the access time of memory from one position to another. So it should be as small and the frequency as high as possible.
After frequency:
SIMM (to be found in older generations of computers)
Current memoirs DIMM divided as follows:
a.DDR1 - DIMM first memories of family memories, slow today. Common possible: 200, 277, 333, 400. Latent: xxxx
b.DDR2 - memories with higher frequencies and better then later. These memories were more stable than their predecessors. Common possible: 533, 677, 800. Latent best: 3-3-3-3
c.DDR3 - the fastest memory, when writing this article with higher frequencies than previous but still not better than latent DDR2 memory. Common possible frequencies: 1600, 3200. Best latency: 4-4-4-4
SODIMM memory used laptops
caches
Processor to perform calculations is using RAM memory. It often happens that certain calculations to be repeated and to not be redone is kept in cache memory, a very fast processor and built-in today, to be accessible as quickly as possible.
Caches are classified into three levels: L1, L2, L3.
Transfer speed increases from L1 to L3. Memories L3 are definitely the best but with very low capacity. Currently there are still many processors without L3 memory and some even without L2.
Might say, why still incorporate memory in L1 and L2 processors if are slower since. If we look at the price will be easy to understand why, so it opted for a much cheaper option and that slows down a CPU with only 10%. The processor includes an amount to approximately 2MB memory of L1, 1MB of L2 and 256 KB of L3. These capabilities are not standard, but one example, they can have different variations.
How it works
Operation is based on the electrical pulse.
The use
Computer memory, is the place where information is processed by the processor, video card and the other components thereof.
Storage mode
Registration information is based on electric fields with values 0 and 1.
