_________________ is where computer systems as on date do not possess any common sense because no full-proof algorithm is designed to programme common sense.

  1. Lack of Commonsense

  2. Zero IQ

  3. Lack of Decision-making

  4. Both b and c
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The inability of computers to handle situations requiring common sense is due to the fact that common sense is based on vast, unstructured human experience that is difficult to codify into algorithms.

Multiple choice

What is the third step in the boot process?

  1. BIOS

  2. GRUB

  3. POST

  4. INIT
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The typical boot process sequence is: 1. BIOS/UEFI, 2. POST, 3. Bootloader (GRUB), 4. Kernel, 5. Init. Therefore, GRUB is the third step.

Multiple choice

A hybrid computer _________________.

  1. Resembles digital computer

  2. Resembles analogue computer

  3. Resembles both a digital and analogue computer

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A hybrid computer Resembles both a digital and analogue computer.

Hybrid computers are computers that exhibit features of analog computers and digital computers. The digital component normally serves as the controller and provides logical and numerical operations, while the analog component often serves as a solver of differential equations and other mathematically complex equations.

It contains the parts of an analoge computer and these from a digital computer. Hybrid Computer A hybrid is a combination of digital and analog computers. ... ... Difference between Analog computers digital computers & Hybrid computers Digital Computers operate on inputs and outputs which are in the form of ON-OFF signal.

Digital computer process data which is binary, i.e. in the form of 0 and 1. Analog computers operate on mathematical variables in the form of physical quantities that are continuously varying. For example temperature, pressure, voltages, etc. The basis of the working of the analog computers is modeling.
