Question 5 of 20

Assertion (A): The Analytical Engine fundamentally differed from the Abacus by incorporating a working memory and an ALU. Reason (R): The Abacus relied merely on sliding beads on wires for simple arithmetic operations, lacking complex logic or flow control.

Question 6 of 20

Given below are two statements, one labeled as Assertion (A) and the other as Reason (R). Assertion (A): Line printers boast significantly higher industrial output speeds than standard Dot Matrix or Daisy Wheel printers. Reason (R): Instead of traversing the page horizontally to print character by character, a Line printer utilizes a rotating drum or chain to stamp an entire horizontal line of text simultaneously. Choose the correct option:

Question 7 of 20

Which of the following defines the primary responsibility of the Control Unit (CU) regarding 'instructions'?

Question 8 of 20
