Q1. The term ‘computer’ is derived from? (A) German Language (B) Sanskrit Language (C) Latin Language (D) Greet Language
Ans: (C) Latin Language
● Explanation:
The word computer is derived from the Latin word ‘computare’, which means ‘to calculate’, ‘to count’, ‘to think’, or ‘to sum up’.
Q2. Who is also known as ‘The Father of Computer? (A) Martin Cooper (B) Charles Babbage (C) J.L Beard (D) Graham Bell
Ans: (B) Charles Babbage
● Explanation:
Charles Babbage was considered to be the father of computing after his invention and concept of the Analytical Engine in 1837. The Analytical Engine contained an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory; hailed as the first general-purpose computer concept.
Q3. What was the name of first computer designed by Charles Babbage? (A) ENIAC (B) Colossus (C) Ferranti Mark 1 (D) Analytical Engine
Ans: (D) Analytical Engine
● Explanation:
Charles Babbage was considered to be the father of computing after his invention and concept of the Analytical Engine in 1837. The Analytical Engine contained an Arithmetic Logic Unit (ALU), basic flow control, and integrated memory; hailed as the first general-purpose computer concept.
Q4. A —————- is an electronic device that processes data and converts it into information? (A) Styles (B) Computer (C) Processor (D) None of these
Ans: (B) Computer
● Explanation:
A computer is an electronic machine that processes raw data to give information as output. An electronic device that accepts data as input, and transforms it under the influence of a set of special instructions called Programs, to produce the desired output (referred to as Information).
The processor, also known as the CPU, provides the instructions and processing power the computer needs to do its work. The more powerful and updated your processor, the faster your computer can complete its tasks.
By getting a more powerful processor, you can help your computer think and work faster.
Q5. When was the first operating system developed? (A) 1948 (B) 1949 (C) 1950 (D) 1951
Ans: (C) 1950
● Explanation:
The first Operating System was developed in the mid 1950s. Before the dawn of operating systems, a computer could execute only one program at a given time. The original operating systems were essentially in charge of allowing numerous applications to run at the same time and then calculating the CPU’s billing expenses accordingly. They functioned as managers This was known as a single-stream batch processing system. Besides supervising programs, these were also responsible for I/O operations.
The first Operating System was GMOS by General Motors for IBM 701.
Q6. In which generation operating systems were developed? (A) 1st Generation (B) 2nd Generation (C) 3rd Generation (D) 4th Generation
Ans: (C) 3rd Generation
● Explanation:
From Third generation operating systems were developed.
In response, individual mainframe computer owners began to develop system software that made it easier to write and run programs and operating systems were born. An operating system ( OS ) is software that manages computer hardware and system resources and provides the tools that applications need to operate.
The period of third generation was from 1965-1971. The computers of third generation used Integrated Circuits (ICs) in place of transistors. A single IC has many transistors, resistors, and capacitors along with the associated circuitry. The IC was invented by Jack Kilby.
Q7. What is an operating system? (A) A set of programs which controls computer working (B) A set of devices and programs (C) A way of computer drives works (D) All of the above
Ans: (A) A set of programs which controls computer working
● Explanation:
An Operating System (OS) is an interface between a computer user and computer hardware. An operating system is a software which performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.
An operating system is software that enables applications to interact with a computer’s hardware. The software that contains the core components of the operating system is called the kernel.
Q8. What is the primary purpose of operating system? (A) Make computer easier to use (B) Allow people to use the computers (C) Keep system programmers employed (D) Make the most efficient use of the hardware
Ans: (D) Make the most efficient use of the hardware
● Explanation:
The primary purposes of an Operating System are to enable applications (spftwares) to interact with a computer’s hardware and to manage a system’s hardware and software resources.
Some popular Operating Systems include Linux Operating System, Windows Operating System, VMS, OS/400, AIX, z/OS, etc.
Q9. Which of the following is not an operating system? (A) Windows (B) Oracle (C) Linux (D) DOS
Ans: (B) Oracle
● Explanation:
Some popular Operating Systems include Linux Operating System, Windows Operating System, VMS, OS/400, AIX, z/OS, DOS etc.
Q10. Integrated Circuits or ICs belong to which generation of computer? (A) 1st Generation (B) 2nd Generation (C) 3rd Generation (D) 4th Generation
Ans: (C) 3rd Generation
● Explanation:
1. First Generation Computers (1942 to 1954) – Based on Vacuum Tubes
2. Second Generation of Computers (1955 to 1964) – Based on Transistor
3. Third Generation of Computers (1965 to 1974) – Based on Integrated Circuit
4. Fourth Generation of Computers (1975– till now )- Based on VLSI Microprocessor
5. Fifth Generation of Computers ( Still in Process)-Based on ULSI Microprocessor, Artificial Intelligence (AI)
