Computer Fundamental Miscellaneous(Computer Fundamentals ) Questions and answers for exam Preparation

Question 1. The most common input device used today is

Explanation:-

Answer: Option E. -> Keyboard
Keyboard is the most common input device of a Computer System. The keyboard resembles a typewriter. Modern Keyboards have more than just the letter and numeric keys. They have multimedia keys for volume control, Play/Pause videos etc.

Question 2. A factor which would strongly influence a businessperson to adopt a computer is its:

Explanation:-

Answer: Option D. -> All of the above
A factor which would strongly influence a businessperson to adopt a computer is its Accuracy, Reliability, Speed and all of the above.

Question 3. Which of the following is the fastest?

Explanation:-

Answer: Option A. -> CPU
Registers are the fastest means of access for CPU. Registers are the small memory locations which are present closest to the CPU.

Question 4. What is the name of the temporary data storage area between a peripheral device and the CPU which compensates for the difference between their speeds?

Explanation:-

Answer: Option B. -> Buffer
Buffer is used to compensate for difference in speed between two processes that exchange or use data. Cache is a smaller and fastest memory component in the computer.

Question 5. In which year were chips used inside the computer for the first time?

Explanation:-

Answer: Option B. -> 1975
In which year were chips used inside the computer for the first time 1975. Most have one chip, however one chip may have several cores which can run several concurrent processes or more in a hyperthreaded manner.

Question 6. An input/output device at which data enters or leaves a computer system is

Explanation:-

Answer: Option B. -> Terminal
A device used to enter data into a computer. It may refer to a one-way handheld data terminal used for data collection; however, "input terminal" often refers to an input/output terminal, in which a screen, readout or printer provides feedback from the computer. See terminal.

Question 7. Which of the following is a secondary memory device?

Explanation:-

Answer: Option B. -> Disk
Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and floppy disks. The hard disk has enormous storage capacity compared to main memory.

Question 8. The register which keeps track of the execution of a program and which contains the memory address of the instruction currently being executed is known as

Explanation:-

Answer: Option C. -> Program counter
Program counter : A program counter is a register in a computer processor that contains the address (location) of the instruction being executed at the current time. As each instruction gets fetched, the program counter increases its stored value by 1. After each instruction is fetched, the program counter points to the next instruction in the sequence. When the computer restarts or is reset, the program counter normally reverts to 0.

Question 9. The input and output devices are located away from the central computer facility in which particular type of processing.

Explanation:-

Answer: Option B. -> Batch processing
Batch processing requires separate programs for input, process and output. An example is payroll and billing systems.

Question 10. The fastest type of memory from the following list is

Explanation:-

Answer: Option B. -> semiconductor memory
Semiconductor memory is a digital electronic data storage device, often used as computer memory, implemented with semiconductor electronic devices on an integrated circuit (IC).
