• He has served as Cabinet Minister of Social Justice and Empowerment in Rajasthan State Government.
• He also served as the Education Minister.

Additional Information

• Ministry of Social Justice and Empowerment:
  • It is responsible for welfare, social justice, and empowerment of marginalized sections of society like SCs, STs, and LGBTQ, etc.
  • At the centre, Thaawar Chand Gehlot is the Minister of Social Justice and Empowerment.

Concept:

ER model describes data as entities, relationships, and attributes. It is a high-level conceptual data model. This model is used to define the data elements and relationships for a specified system.

Entity:

The entity is a thing in the real world with an independent existence. An entity may be an object with physical existence. For example particular person, car or it may be an object with a conceptual existence For example company, job, etc.

Attributes:

Each entity has attributes – the particular properties that describe it.

Relationship:

It is used to describe the relation between two entities.

Explanation:

E-R Diagram is design level task and Relational model is implementation.

The relational model is implemented from E-R Diagram and in this, it gets rid of the multivalued attributes.

Relations produced from the E - R Model will always be in 1NF, that is, Simple atomic values with non-multivalued attributes.

NOTES:

The correct answer is A Central processing unit.

Key Points

• Central Processing Unit(CPU)
  • A CPU is also called a central processor, main processor, or just processor, is the electronic circuitry that executing instructions comprising a computer program.
  • The CPU performs basic arithmetic, logic, controlling, and input/output operations specified by the instructions in the program.
  • The fundamental operation of most CPU's regardless of the physical form they take is to execute a sequence of stored instructions called a program. 
• Instructions cycle in CPU
  • All CPU's follows the following steps in order to complete their operations:
    1. Fetch: The first step, involves retrieving instructions from the program memory.
    2. Decode: The instruction that the CPU fetches from the memory determines what the CPU will do, which is decoded by the instructor decoder.
    3. Execute: In this step, all the desired functions are performed as per the instructions decoded.
• Intel Core
  • ​Intel core are streamlined computers CPU marketed by Intel Corporation.
  • Brand Names: Core, Core 2, Core i3, Core i5, Core i7, Core i9
  • Launched: January 2006
  • Founders: Gordon Moore Robert Noyce
  • Headquarters: Santa Clara, California, USA

Additional Information

The correct answer is Memory.

Key Points

• The memory mapping process is handled by the virtual memory manager, which is the same subsystem responsible for dealing with the page file.
• Memory-mapped files are loaded into memory one entire page at a time.
• The page size is selected by the operating system for maximum performance. 

Additional Information

• A memory
  • It is just like a human brain.
  • It is used to store data and instructions. 
  • Computer memory is the storage space in the computer, where data is to be processed and instructions required for processing are stored.
  • The memory is divided into a large number of small parts called cells.
• Process
  • It is the instance of a computer program that is being executed by one or many threads.
  • It contains the program code and its activity.
  • Depending on the operating system, a process may be made up of multiple threads of execution that execute instructions concurrently.
• A computer file
  • It is a computer resource for recording data in a computer storage device.
  • Just as words can be written to paper, so can data be written to a computer file.
  • Files can be edited and transferred through the Internet on that particular computer system.
• Computer security
  • cybersecurity or information technology security is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.

CONCEPT:

• Force: The interaction which after applying on a body changes or try to change the state of motion or state of rest is called force.
• Force is denoted by F and the SI unit is Newton (N).

• Force (F) = Mass (m) × acceleration (a)

EXPLANATION:

• Both Dyne and Newton are units of force in the CGS and S.I system.
• Newton and dyne can also be written as (1 N = kg-m/s2) and (1 dyne = gm-cm/s2).
• The relation between the Newton and  Dyne is given as 

⇒ 1 N = 105 dyne

• Therefore, the ratio of SI unit and CGS unit of force is

\(\Rightarrow \frac{N}{Dyne} = 10^5\)
