Question 16

Motherboard

Answer 16

is a large circuit board that holds computer components. Its called a motherboard
because of its capability to extend its capabilities with the addition of daughterboard’s or add on cards. It
is also called the mainboard.

Question 17

Who is George Boole was and what did he contribute.

Answer 17

English mathematician who helped establish modern symbolic logic and whose algebra of logic, now called Boolean algebra, is basic to the design of digital computer circuits.

Question 18

Boolean Operations

Answer 18

Operations that manipulate true/ false
values.
