Question Discussion & Solution

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.

The correct answer is Viceroy Curzon.

Key Points

• Lord Curzon:
  • ​He served as Governor-General of India from 1899 to 1905.
  • He passed the Calcutta Corporation Act in the year 1899.
  • According to the act, it increased the number of official members and decreased the strength of elected official members.
  • As official members were mostly British Subjects it caused resentment in the Indian public.
  • He was the Viceroy who passed a law for protecting Ancient Indian monuments.
  • He passed the law in 1904 made the destruction of Ancient Monuments an offence and directed officials to collect and preserve ancient monuments.
  • British viceroy in India, Lord Curzon, carried out Partition of Bengal, (1905) despite strong Indian nationalist opposition.

Additional Information

• The Partition of Bengal was announced on 19 July 1905 by the then Viceroy Lord Curzon.
  • And was implemented on 16 October 1905
  • However, in 1911 it was withdrawn by Lord Hardinge.
• The stated reason was to ease the administration.
  • But the actual reason was to weaken the growing nationalism in Bengal and break the unity.
• As per Curzon, after the partition, the two provinces would be Bengal (including modern West Bengal, Odisha, and Bihar) and Eastern Bengal and Assam.
• Annulment of Bengal:
  • The partition of Bengal was annulled in 1911 by Lord Hardinge.
  • The capital of British India was moved to Delhi from Calcutta in 1911.
  • Despite the annulment, the partition already succeeded in making a communal divide between Muslims and Hindus of Bengal.

The correct answer is Open Cast Mining.

• Open Cast Mining is the process under which minerals are mined near the earth's surface.

Key Points

• Opencast mining is the process that involves the removal of ore from seams relatively near the surface by means of an open-pit.
• These mines occupy a large area of land for excavation of the ore and disposal of the overburden.

Additional Information

• Drilling is a cutting process which uses a drill bit to cut a hole of circular cross-section in solid materials or ground.
• Quarrying is the process of removing rock, sand, gravel or minerals from the ground in order to use them to produce materials for construction or other uses.
• Shaft mining is the process where miners dig straight down until they reach their desired depth. 

Functional cohesion:

A module is said to possess functional cohesion, if different functions of the module co-operate to complete a single task.

Example of Functional cohesion

A module containing all the functions required to manage employees’ pay-roll displays functional cohesion

CONCEPT:

• Power: The rate of work done is called power.
  • It is denoted by P.
  • Mathematically it is written as

\(Power\;\left( P \right) = \frac{{\;W}}{{t}}\)

CALCULATION:

Given - mass of 1^st person (m₁) = 80 kg, mass of 2^nd person (m2) = 60 kg, time (t₁) = 12 sec, and time (t2) = 11 sec​

• The power to take an object to a certain height in 12 sec by 1^st person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{80gh}{12}\)       ----(1)

• The power to take an object to a certain height in 11 sec by 2^nd person is 

\(\Rightarrow P_1 = \frac{mgh}{t}=\frac{60gh}{11}\)       ----(2)

On dividing equations 1 and 2, we get

\(\Rightarrow \frac{P_1}{P_2} =\frac{\frac{80gh}{12}}{\frac{60gh}{11}}=\frac{11}{9}\)
