Computer Memory: How it Works?

Every computer has its own memory and memory consist many devices which is used to store data in your computer. Storage is of two types one is temporary and second is permanent storage. In a computer setup each memory is made up of numbers of capacitors and transistors. In it capacitor is used to hold the data and transistor is used to read/write data which is held in capacitor.

Speed of computer depends on its memory. If memory is high computer works fine and if memory is less speed and performance of computer decreased. A computer consists of a physical memory built on the motherboard known as RAM and when this memory is not enough to store the data another computer memory is used known as virtual memory. This virtual memory is come up when physical memory of computer is full and it needs some more memory to store the data. This memory can be increased or decreased by system properties through control panel. By using this your computer runs faster. In memory data is written by CPU.

Address of each memory location is written in hexadecimal format. CPU performs the function of reading and writing of data from this memory location. In computer memory capacitor and transistors are managed in rows and columns form. The very common type of memory used by computer is RAM which stores the data at very high speed. It has an option to store data temporary. It is volatile in nature that is all the stored data is lost when power is off, this is the main disadvantage of RAM.
