Answer:
i-true
ii-true
iii-false
iv-true
v-false
vi-true
Answer:
1:True
2:True
3:True
4:False
5:False
6:False
Explanation:
1: Just like keyboard and mouse a scanner gives you the output like scanning a document so scanners are output devices
2:Yes a computer is a versatile device to use so it is True
3:Yes Analog computers use physical quantities as input device like keyboard and mouse are input devices for modern computers
4:Charles Babbage became the father of Personal computers after he invented the analytical engine in 1837
5: Second generation computers used transistors instead of vacuum tubes since the first generation computers used vacuum tubes it could only solve 1 question at a time
6 Mainframe computers are faster than Personal Computer (PC) because Mainframe computers have more speed and storage
