FAQs on Computer Memory Video Lecture - IBPS PO Prelims & Mains Preparation - Bank Exams

1. What are the different types of computer memory?

Ans. Computer memory can be broadly categorized into two types: primary (or volatile) memory and secondary (or non-volatile) memory. Primary memory includes RAM (Random Access Memory), which is used for temporary data storage while a computer is in use, and cache memory, which provides high-speed data access. Secondary memory includes storage devices like hard drives, SSDs (Solid State Drives), and optical disks, which store data permanently or for long-term use.

2. How does RAM affect computer performance?

Ans. RAM (Random Access Memory) is crucial for computer performance as it allows for quick read and write access to data that the CPU needs immediately. More RAM means that a computer can handle more applications simultaneously and run more complex programs without slowing down. Insufficient RAM can lead to increased reliance on slower secondary storage, causing performance bottlenecks.

3. What is the difference between RAM and ROM?

Ans. RAM (Random Access Memory) is a type of volatile memory that temporarily stores data that the CPU needs while a computer is running. When the power is turned off, all data in RAM is lost. In contrast, ROM (Read-Only Memory) is non-volatile memory that permanently stores critical system information, such as firmware, and retains this information even when the power is off. ROM cannot be easily modified or written to.

4. Why is cache memory important in a computer system?

Ans. Cache memory is a small-sized type of volatile memory that provides high-speed data access to the CPU. It stores frequently accessed data and instructions, allowing the CPU to retrieve them faster than if it had to access the main RAM. This significantly improves the overall performance and speed of the computer, particularly during resource-intensive tasks.

5. How can I improve my computer's memory performance?

Ans. To improve your computer's memory performance, you can upgrade your RAM by adding more memory modules to increase capacity, which allows for better multitasking and smoother operation of applications. Additionally, you can optimize memory usage by closing unused applications, clearing temporary files, and ensuring that your system has adequate virtual memory configured. Regularly updating your operating system and drivers can also help improve memory performance.
