5. Read-only memory is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM can only be modified slowly. It consists of a programmed integrated circuit that doesn't lose data when powered down, making it nonvolatile.


*******

6. Computer programs and operating systems load into RAM. If it has a lot of processes running at one time, RAM may become overworked and performance can suffer.


*******

7. The speed of system random-access memory is determined by two factors: bus width and bus speed. Bus width refers to how many bits of information RAM can send to the CPU at the same time.


*******

8. BIOS instructions set up the computer and boot the operating system. The BIOS's primary function is to handle the system setup process including driver loading and operating system booting.


*******

9. Auxiliary memory, also known as Secondary memory or External memory, is a non-volatile memory. Secondary Memory isn't directly accessible to the CPU like primary storage.


*******

10. Static random-access memory is a type of memory that uses bistable latching circuitry to store each bit. SRAM is volatile in the conventional sense that data is eventually lost when the memory is not powered.


*******

11. Motherboard holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit and memory, and provides connectors for other peripherals.


*******

12. Primary memory is computer memory that is accessed directly by the CPU. Primary memory is the main memory of the computer which can be directly accessed by the central processing unit,.


*******

13. RAM is a memory which is both read and written. Random-access memory is a form of computer data storage that stores data and machine code currently being used.


*******

14. Virtual memory is that uses hardware and software to allow a computer to compensate for physical memory shortages by temporarily transferring data from random access memory (RAM) to disk storage.


*******

15. A nibble is a four-bit aggregation. It is also known as half-byte or tetrade. A nibble can be conveniently represented by one hexadecimal digit.


*******

16. The platters of a hard disk have two sides for recording the data. Every surface of the platter has invisible concentric circles on it. These circles are called tracks.


*******

17. The flip flop is an electronic circuit with two stable states that can be used to store binary data. Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers and communications.


*******

18. The main memory in a computer is called Random Access Memory. It is also known as RAM. This is the part of the computer that stores operating system software.


*******

19. Nano-RAM is a computer memory technology . It is developed by Nantero. It is a type of nonvolatile random access memory. Nantero was founded in 2001, and headquartered in Woburn, Massachusetts.


*******

20. Virtual Memory is an imaginary memory area supported by some operating systems. Virtual memory combines computer's RAM with temporary space on your hard disk.
