Q5. Give examples for each of system software and application software. Explain the function of each type.

Ans. Examples of system software are:

(i)                  Operating System

(ii)                Language Processor

(iii)               Application Software

Examples of Operating System are: Single user OS, multiuser OS, batch processing OS, multiprocessing OS, etc.

As the name suggest, single user OS supports single user whereas multiuser OS can support multiple users. The batch Processing OS process the batches (groups) of jobs (processes given to it) and multiprocessing OS is capable of handling multiple CPUs at the same time. The examples of language processors are:

(i)                  Interpreter

(ii)                Complier

(iii)               Assembler

An interpreter converts and executes a high level language program into object program line by line whereas a complier converts a high level language program into object program in one go and once the program is error free, it can be executed later. An assembler converts an assembly language program into object program.

Examples of application software are:

(i)                  Customized Software

(ii)                General Software

The customized software pertains to the requirements of a specific user for whom the software has been developed. General software is developed keeping in mind general specification of a problem.

Q3. What is the function of memory? What are its measuring units?

Q3. What is the function of memory? What are its measuring units?

Ans. The memory temporarily holds the data and information during processing.

The smallest unit of memory is a byte (8 bits). A byte can store one character in binary form. Other measuring units are kilobyte (KB) equal to 1024 (210) bytes, Megabyte (MB) equal to 1024 KB, Gigabyte (GB) equal to 1024 MB and Terabyte (TB) equal to 1024 GB.

Q2. State the basic units of the computer. Name the subunits that make up the CPU, and give the function of each of the units.

Q2. State the basic units of the computer. Name the subunits that make up the CPU, and give the function of each of the units.

Ans. The basic units of a computer are:

  1. Input Unit
  2. Central Processing Unit (CPU)
  3. Output Unit
  4. Memory

The CPU has two subunits: the control unit (CU) and the arithmetic logic unit (ALU).

The control unit controls the entire operation being carried out.

The ALU performs the arithmetic and logical operations.
