what is RAM? And how does it work?

Answer: Ram : Random Access Memory, which is a type of temporary memory. The memory that is directly connected to the motherboard and can perform both read and write tasks is called RAM. It is a temporary memory. As long as the computer is powered on, RAM stores information in RAM. As soon as the power supply is turned off, RAM erases all its information. Therefore, it is called temporary memory. RAM is usually used to support and change information. Since RAM can be used for both reading and writing, it is also called read-write memory. The computer user can store information in RAM and delete the saved information and put new information again.

RAM can be divided into two parts according to the operating mode. Namely-

1. Static RAM and
2. Dynamic RAM.

Dynamic RAM (DRAM):
This type of RAM is usually made using MOSFET (MOSFET= Metal Oxide Semiconductor Field Effect Transistor) and capacitors. If the capacitor is charged, it means 1 state, if not, it means 0 state. Even when there is electricity, the charge of the capacitor is gradually lost. Therefore, the information written in each memory cell has to be rewritten every few milliseconds with the help of a drum controller. In computer terminology, this is called memory refreshing. Both static and dynamic RAM are volatile. Information can be erased and written repeatedly in all these RAMs. As new information is written, the old information is automatically erased. (DRAM) is usually used as the main memory of microcomputers.

Static RAM (Static Ram):
This type of RAM is usually made using TTL (TTL=Transistor-Transistor Logic) or (Metal Oxide Semiconductor). Data and information are stored in static RAM as long as the electricity is on. Static RAM is very fast and is used in video RAM, cache memory, etc.
