The doubt is from The Input Unit topic in chapter Basic Computer Organisation of Computer Fundamentals

This set of Computer Fundamentals Multiple Choice Questions & Answers (MCQs) focuses on “The Input Unit”.

1. Which unit is responsible for converting the data received from the user into a computer understandable format?
a) Memory Unit
b) Arithmetic & Logic Unit
c) Input Unit
d) Output Unit
View Answer

Answer: c
Explanation: The Input Unit converts the data, which the user enters into a language which the computer understands, i.e. it converts the data into binary format. The Output Unit is responsible for giving the results in user-understandable format. The Storage Unit is responsible for storing the data after immediate results of processing whereas; the ALU is responsible for various arithmetic and bitwise operations.

2. The only language which the computer understands is ______________
a) Assembly Language
b) Binary Language
c) BASIC
d) C Language
View Answer

Answer: b
Explanation: The Computer understands only binary language which is written in the form of 0s & 1s. A computer can understand assembly language but an assembler is required which converts the assembly language to binary language. Similarly, for understanding high level languages, compilers/interpreters are required.

3. The smallest unit of data in computer is ________________
a) Byte
b) Nibble
c) Bit
d) KB
View Answer

Answer: c
Explanation: A bit is defined as the smallest unit of data in a computer system. It is used as a short form of Binary Digit. A bit can have only two values 0 or 1. A nibble comprises of 4 bits, a byte is a collection of 8 bits whereas KB (Kilobyte) is equal to 1024 bytes.

4. One nibble is equivalent to how many bits?
a) 2
b) 4
c) 8
d) 1
View Answer

Answer: b
Explanation: A nibble is defined as a unit of data which comprises of 4 binary digits or half of 8-bit byte. Therefore, 1 nibble = 4 bits. A bit is the smallest unit of data in a computer system. A byte = 8 bits, therefore, half of a byte=4 bits=a nibble.

5. Which of the following describes the correct format of an input instruction?
a) IN 82
b) INPUT 82
c) INP 82
d) 82 INP
View Answer

Answer: a
Explanation: The input/output instructions are used to transfer information between external peripherals and the CPU. The correct format of an input instruction is: IN 8-bit port address.
Here, IN 82 is the correct option, where 82 is the designated port address. All the other options are invalid.

6. The input machine which originated in the United States around 1880s is a ___________
a) Mouse
b) Joystick

7. What does the COMPUTER stand for?
a) Commonly Operated Machines Used in Technical and Educational Research
b) Commonly Occupied Machines Used in Technical and Educational Research
c) Commonly Operated Machines Used in Technical and Environmental Research
d) Commonly Oriented Machines Used in Technical and Educational Research
View Answer

Answer: a
Explanation: The word COMPUTER is an abbreviation for the terms “Commonly Operated Machines Used in Technical and Educational Research”. The word COMPUTER also relates to the word COMPUTE which means to calculate. So, initially it was thought that a computer is a device which is used to perform calculations.

8. 1 yottabyte = ______________
a) 1024 TB
b) 1024 EB
c) 1024 ZB
d) 1024 PB
View Answer

Answer: c
Explanation: 1 yottabyte is equal to 1024 ZB, which stands for zettabyte. Further, 1 ZB=1024 EB (exabyte) and and 1 EB=1024PB (petabyte).

9. Which of the following is not a function of the Input Unit?
a) It reads instructions and data from the outside world
b) It converts the data into computer acceptable format
c) It makes the data into user understandable format
d) It supplies the data and instructions to the computer for further processing
View Answer

Answer: c
