Question Discussion & Solution

Joule is the SI unit of Energy.

Similarly,

Pascal is the SI unit of pressure.

Hence, pressure is the correct answer.

Additional Information 

* S.I Unit of Resistance is the Ohm.

* S.I Unit of Energy is Joule.

* S.I Unit of Volume is the Cubic meter.

* S.I Unit of Force is Newton.

* S.I Unit of Area is the Square meter.

* S.I Unit of Temperature is Kelvin.
Important Points 

There is a total of 9 S.I units.

1. 7 of them are fundamental units.

2. 2 of them are Supplementary units.

The Correct answer is Uniform motion.

Key Points

• Motion​:
  • It is a phenomenon in which an object changes its position with respect to time.
  • All motions are relative to some frame of reference. 
  • There are two types of motion:
    • Uniform Motion
    • Non-uniform Motion
• Uniform motion:
  • If an object is traveling with uniform motion, it is moving in a straight line at a constant speed.
  • For example, An object falling at terminal velocity experiences the same air resistance as its weight.
  • Newton's first law can be used to explain the movement of objects traveling with uniform motion.
  • Newton's first law is a body that is at rest or moving at a uniform rate in a straight line will remain in that state until some force is applied to it.

​Additional Information

• Retarding motion: The Motion in which the speed of the body gradually decreases.
• Non-uniform motion: If a body covers unequal distances in equal intervals of time
• Non-linear Motion: Nonlinear motion is motion along a curved path; It is the combination of two components of motion' horizontal motion (without acceleration) vertical motion (under the acceleration of gravity).

'Loyalty', 'Allegiance', and 'Commitment' are synonyms.

Whereas, 'Infidelity' is an antonym of 'Loyalty'.

Hence, the correct answer is 'Infidelity'.

The correct answer is BIOS.

BIOS is not a computer operating system.

Important Points

• BIOS (basic input/output system)
  • It is a program that is used by a computer's microprocessor to start the computer system after it is powered on.
  • It also manages data flow between the computer's operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer.

Key Points

• The Unix
  • A Unix family is a diverse group of operating systems, with sub-categories including System V, BSD, and Linux.
  • The name "UNIX" is a trademark of The Open Group which licenses it for use with any operating system that has been shown to conform to their definitions. 
• macOS 
  • It is an open core graphical operating system.
  • It is developed, and marketed, and sold by Apple Inc.
• Microsoft Windows
  • It is a family of proprietary operating systems designed by Microsoft Corporation.
  • It is primarily targeted at Intel architecture based computers.

Additional Information

• Operating system
  • An operating system (OS) is system software that manages computer hardware, software.
  • An operating system is a large and complex system.
  • OS system components include:
    • File,
    • Process,
    • Memory,
    • I/O device management.

The correct answer is option 2 i.e. Character, Field, Record, File, Database.

Additional Information

• A character is any letter, number, space, punctuation mark, or symbol that can be typed on a computer.
• The word "computer," for example, consists of eight characters.
• The term "fields" refers to columns or vertical categories of data.
• A record is composed of fields and contains all the data about one particular person,
• A file is the common storage unit in a computer, and all programs and data are "written" into a file and "read" from a file.
• A database is an organized collection of structured information, or data, typically stored electronically in a computer system.
• A database is usually controlled by a database management system (DBMS).
