IBPS PO General Awareness: Computer Fundamentals questions with solutions

Q1. The binary system uses powers of

1. 2
2. 10
3. 8
4. 16

Answer: 2

The binary number system is based on 2. Its place values are powers of 2, such as 1, 2, 4, 8, and so on.

Q2. What was the language used in second-generation computers?

1. Assembly Language
2. Basic Language
3. Machine Language
4. Pascal

Answer: Assembly Language

Second-generation computers used assembly language, which is a symbolic low-level language. Machine language was used in first-generation computers, while BASIC and Pascal are higher-level languages.

Q3. Third-generation language is

1. machine language
2. assembly language
3. high-level language
4. middle-level language

Answer: high-level language

Third-generation languages (3GLs) are high-level programming languages such as C, FORTRAN, and COBOL. They are more abstract than machine and assembly languages. Therefore, the correct answer is high-level language.

Q4. Which of the following units performs arithmetic tasks such as addition, subtraction, multiplication, and division, and logical operations?

1. Input unit
2. Control unit
3. Arithmetic Logic Unit (ALU)
4. Storage unit

Answer: Arithmetic Logic Unit (ALU)

The Arithmetic Logic Unit (ALU) is the component of the CPU responsible for performing arithmetic calculations and logical comparisons. Input, control, and storage units serve different roles in data handling and instruction management.

Q5. Which printer cannot print graphics?

1. Daisy Wheel printer
2. Inkjet printer
3. Laser printer
4. Digital printer

Answer: Daisy Wheel printer

A Daisy Wheel printer is an impact printer that prints only text characters and cannot print graphics. Inkjet and laser printers can print graphics, so they are not correct.

Q6. Match the following generations of computers with the technology used in each generation. 1. 1st Generation 2. 2nd Generation 3. 3rd Generation 4. 4th Generation I. Microprocessors II. Vacuum Tubes III. Integrated Circuits IV. Transistors

1. 1.II 2.IV 3.I 4.III
2. 1.II 2.IV 3.III 4.I
3. 1.II 2.I 3.IV 4.III
4. 1.I 2.II 3.III 4.IV

Answer: 1.II 2.IV 3.III 4.I

The 1st generation of computers used vacuum tubes, the 2nd used transistors, the 3rd used integrated circuits, and the 4th used microprocessors. Matching them gives 1.II, 2.IV, 3.III, 4.I.

Q7. Which are common file operations performed by system calls?

1. Create
2. Open
3. Read and Write
4. All of these

Answer: All of these

System calls provide low-level access to operating system services, including file handling. Common file operations include creating, opening, reading, and writing files, so the inclusive option is correct.

Q8. Expand RDBMS.

1. Relative Database Management System
2. Rational Database Minimize System
3. Relational Database Management System
4. Relational Database Maximize System

Answer: Relational Database Management System

RDBMS stands for Relational Database Management System. It is the standard term used for database systems based on the relational model.

Q9. Checking of different hardware parts of a computer is done by?

1. BIOS
2. Hard disk
3. Processor
4. C.D.

Answer: BIOS

BIOS is the basic input/output system stored on the motherboard. It performs the power-on self-test (POST) and checks hardware components before loading the operating system.
