What are the two types of RAM?
There are two main types of RAM: Dynamic RAM (DRAM) and Static RAM (SRAM). DRAM (pronounced DEE-RAM), is widely used as a computer’s main memory. Each DRAM memory cell is made up of a transistor and a capacitor within an integrated circuit, and a data bit is stored in the capacitor.Which is the most common types of computer?
Laptops, hand-held devices, wearable tech, and desktops are the most common computer types today. Desktops are the oldest computers and are used to run a large variety of programs and access the Internet. Laptops are portable versions of desktops that are smaller so they can be carried around with ease.
Where is RAM stored?
RAM is physically small and stored in microchips. It’s also small in terms of the amount of data it can hold. A typical laptop computer may come with 8 gigabytes of RAM, while a hard disk can hold 10 terabytes.
Which of the following is stored in RAM?
Random Access Memory is a volatile memory and the data is RAM will be lost when power is switched off. As compared to the hard disk or secondary storage device, the RAM can be accessed so fast. So, the information which is used frequently is stored in the RAM.
What kind of data does the RAM store?
Computer random access memory (RAM) is one of the most important components in determining your system’s performance. RAM gives applications a place to store and access data on a short-term basis. It stores the information your computer is actively using so that it can be accessed quickly.

Memory Basics
Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory. It is also called as read write memory or the main memory or the primary memory.
