1.What is meant by overclocking
2. Mention the types of memory
3. How is CMOS used in a computer
4. Define clock speed
1. Overclocking is the process of increasing the speed at which a computer's CPU (central processing unit) operates beyond the manufacturer's recommended specifications. This can result in increased performance, but also carries risks such as overheating and instability.
2. The types of memory used in a computer include:
- Random Access Memory (RAM): This is temporary memory that stores data and instructions for the CPU to access quickly.
- Read-Only Memory (ROM): This is permanent memory that stores firmware and boot-up instructions for the computer.
- Cache Memory: This is high-speed memory located close to the CPU that stores frequently accessed data for faster retrieval.
3. CMOS (Complementary Metal Oxide Semiconductor) is a type of memory chip used in computers to store BIOS settings and configuration information. It retains this information even when the computer is turned off, thanks to a small battery on the motherboard. CMOS is used to store settings such as the system clock, hardware settings, and boot order.
4. Clock speed refers to the frequency at which a CPU operates, measured in cycles per second (Hertz). A higher clock speed means the CPU can process instructions more quickly, leading to improved performance. However, clock speed is not the only factor that determines a CPU's performance, as there are other factors such as architecture and core count to consider.
