Answer 1

Answer:

3. The CPU is made up of three main components, the control unit , the immediate access store and the arithmetic and logic unit .

4. Input Unit

The main function of input devices is to direct commands and data into computers. Computers then use their CPU to process this data and produce output. For example, a laptop's keyboard is an input unit that enters numbers and characters.

5. An arithmetic logic unit (ALU) is a digital circuit used to perform arithmetic and logic operations. It represents the fundamental building block of the central processing unit (CPU) of a computer. Modern CPUs contain very powerful and complex ALUs. In addition to ALUs, modern CPUs contain a control unit (CU).

The purpose of the ALU is to perform mathematical operations such as addition, subtraction, multiplication and division. Additionally, the ALU processes basic logical operations like AND/OR calculations. Also known as the arithmetic logic unit, it serves as the computational hub of the Central Processing Unit (CPU) for a computer system

6. The third and final component of a computer system is the output unit. After processing of data, it is converted into a format which humans can understand. After conversion, the output units displays this data to users. Examples of output devices include monitors, screens, printers and speakers.

7. Memory is basically a device that has the capacity to store information. A memory unit is the amount of data that the memory can hold. Besides, we measure this storage capacity in terms of bytes. Moreover, there are different units of memory as per the requirement.

8.ROM is further classified into 4 types- MROM, PROM, EPROM, and EEPROM.

9. Hard disk.
