Question Discussion & Solution

The correct answer is the Boot sector.

Important Points

• The portion of a disk that contains the master boot record is the Boot sector.
• The MBR contains a partition table, which stores information on which primary partitions have been created on the hard disk so that it can then use this information to start the machine.
• The MBR is stored on the first sector of the hard disk and is created along with the first partition on the drive.
• It is loaded into memory as one of the first actions during system start-up.

Key Points

• The MBR is comprised of a small section of operating system independent code, a disk signature, the partition table, and an MBR signature.
• The disk signature is a unique four-byte identifier for the hard drive.
• It is used for purposes such as identifying the boot volume and associating partitions and volumes with a specific drive.
• The partition table informs of the start position and length of each partition on the hard disk.

Additional Information

The correct answer is Super Computer.

Key Points

• Supercomputers were introduced in the 1960s as the world's most advanced computer.
• A supercomputer is a powerful computer that can process a large amount of data and computation very quickly.
• Supercomputers perform immense amounts of mathematical calculations.
• Super Computers are also known as Number Crunching.
• Supercomputers are used for areas related to:
  • Science
  • Engineering
  • Education
  • Defense
  • Aerospace
• Supercomputers are useful for applications involving very large databases or that require a great amount of computation.
• Supercomputers are used for complex tasks, such as:
  • Weather forecasting
  • Climate research
  • Scientific simulation
  • Oil and gas exploration
  • Quantum mechanics
  • Cryptanalysis

​Important Points

• The First Cray-1 supercomputer was installed at Los Alamos National Laboratory in 1972.
• Param Shivay, the first supercomputer assembled indigenously in India, was installed in IIT (BHU).
• Fugaku (Japan) Jointly developed by RIKEN and Fujitsu, is the fastest supercomputer in the world.
• PARAM-Siddhi AI is the fastest supercomputer in India.

Additional Information 

Sequence should be follow is:

The correct answer is Application software

Important Points

• MS Office, Photoshop, and Animagic are examples of Application software
• MS Office is a software bundle provided by Microsoft.
• It includes software like MS Word, MS Excel, MS Powerpoint, MS Outlook, MS Access, MS One Note, and others.

Additional Information

• Photoshop is a powerful photo editing tool by Adobe.
• An Operating System (OS) is an interface between a computer user and computer hardware.
• An operating system is software that performs all the basic tasks like file management, memory management, process management, handling input and output, and controlling peripheral devices such as disk drives and printers.

The correct answer is Backspace.

Key Points

• The backspace key is used to delete a word or a line.
• Backspace is the keyboard key that originally pushed the typewriter carriage one position backwards, and in modern computer systems moves the display cursor one position backwards.
• It deletes the character at that position, and shifts back the text after that position by one position.

Additional Information

• The Alt key on a computer keyboard is used to change (alternate) the function of other pressed keys.
• Thus, the Alt key is a modifier key, used in a similar fashion to the Shift key. 
• The shift key is a modifier key on a keyboard, used to type capital letters and another alternate "upper" characters. 
• The Insert key insert (often abbreviated Ins) is a key commonly found on computer keyboards.
