Question Discussion & Solution

Fullest is an antonym of emptiest similarly, antonym of clearest is gloomiest (means dark or poorly lit).

Hence, there is one such digit.

The correct answer is Process.

• Creating user and system processes is part of the Process management function of the operating system.

​Key Points

• The process management component:
  • The process management component is a procedure for managing the many processes that are running simultaneously in the operating system.
  • Every software application program has one or more processes when they are running.
  • For example, when we use a browser like Google Chrome, there is a process running for that browser program.
    • All these processes are managed by process management. 
  • The process management uses memory allocated to them and shutting them down when needed.

Additional Information

• Operating system
  • An operating system is a large and complex system.
  • OS system components include:
    • File,
    • Process,
    • Memory,
    • I/O device management.
• File management
  • File management in an operating system includes file creation and deletion.
  • Manipulating files and directories.
• Memory management
  • ​An Operating System performs the functions for Memory Management such as:
    • It helps to keep track of primary memory.
    • Determine what parts of it are in use by whom, what part is not in use.
• I/O device management
  • ​An Operating System performs the functions for I/O device management such as:
    • It offers a buffer caching system
    • It provides general device driver code
    • It provides drivers for particular hardware devices.

The correct answer is Ctrl + Z.

• Ctrl + Z is the shortcut key for undoing a task.

Key Points

• Undo is a function performed to reverse the action of earlier action.
• Any actions that were previously undone using the Undo function are restored using the Redo function.
• For example, if you entered a word and then used the undo function to remove it, the redo function would restore the erased word.

Additional Information

Option 3 is correct, i.e. p-block.

• Modern Periodic Table:
  • The Modern Periodic Table is classified into the following elements - p-block, s-block, d-block, and f-block.
  • The p-block elements include chalcogens, pnictogens, halogens, inert gases.
    • The 18^th group is known as Inert gas, zero groups, Nonreactive gases.
    • The 17^th group is known as Halogen.
    • The 16^th group is known as Chalcogen.
    • The 15^th group known as Pnictogen.
    • Pnictogen group refers to the choking property of nitrogen gas (as opposed to air, which contains oxygen as well as nitrogen).
    • Nitrogen family elements consist of atoms having 5 electrons in their outer energy level. Two of the electrons are in the s subshell, with 3 unpaired electrons in the ​p subshell.
  • The s-block elements include alkali metals and alkaline earth metals. 
  • The d-block elements include Transition elements.
  • The f-block elements include Inner Transition Elements.
