FAQs on Computer Fundamentals- Types of Computer Memory Video Lecture - Computer Science for Class 6
| 1. What are the different types of computer memory? |  |
Ans. The different types of computer memory include RAM (Random Access Memory), ROM (Read-Only Memory), cache memory, virtual memory, and flash memory. Each type of memory serves a specific purpose in a computer system.
| 2. What is the function of RAM in a computer? | |
Ans. RAM (Random Access Memory) is a type of computer memory that is used for temporary storage of data that is actively being used by the computer's processor. It allows quick access to data, enabling faster execution of programs and efficient multitasking.
| 3. What is the difference between RAM and ROM? | |
Ans. The main difference between RAM (Random Access Memory) and ROM (Read-Only Memory) is that RAM is volatile memory that can be read from and written to, while ROM is non-volatile memory that can only be read from. This means that the data stored in RAM is temporary and gets erased when the computer is turned off, whereas the data stored in ROM is permanent and remains even when the power is turned off.
| 4. What is cache memory and what is its purpose? | |
Ans. Cache memory is a small, high-speed memory that is located closer to the processor in a computer system. Its purpose is to store frequently accessed data and instructions, providing faster access to the processor. By storing data closer to the processor, cache memory reduces the time it takes to retrieve data from the main memory, improving overall system performance.
| 5. What is virtual memory and how does it work? | |
Ans. Virtual memory is a technique used by computer operating systems to provide more memory than is physically available in the system. It uses a portion of the computer's hard disk as an extension of the RAM. When the RAM becomes full, the operating system moves less frequently used data from RAM to the hard disk, freeing up space in the RAM for other tasks. When the data is needed again, it is swapped back into the RAM from the hard disk. This allows the computer to run larger programs and handle more tasks simultaneously.
