Answer:
The major characteristics of computers are the following:
Speed : A powerful computer is capable of executing about 3 million calculations per second.
Accuracy : A computer's accuracy is consistently high; if there are errors, they are due to errors in instructions given by the programmer.
Reliability : The output generated by the computer is very reliable as long as the data is reliable.
Memory/Storage Capacity : The computer can store large volumes of data and makes the retrieval of data an easy task.
Versatility: The computer can accomplish many different things. It can accept information through various input-output devices, perform arithmetic and logic operations, generate a variety of outputs in a variety of forms, etc.
Automation: Once the instructions are fed into computer it works automatically without any human intervention.
Diligence: A computer will never fail to perform its task due to distraction or laziness.
Convenience: Computers are usually easy to access, and allow people to find information easily that without a computer would be very difficult.
Flexibility: Computers can be used for entertainment, for business, by people who hold different ideals or who have varied goals. Almost anyone can use a computer, and computers can be used to assist with almost any goal.

Answer:
1. 'NOT(TRUE AND FALSE) AND TRUE'
3. 'NOT (TRUE AND TRUE) OR TRUE'
Explanation:
We can go through each option to find out which statements will result in a 'TRUE' value.
1. <u>'NOT (TRUE AND FALSE) AND TRUE':</u>
'TRUE AND FALSE' inside the parentheses will result in 'FALSE' since the Boolean operator 'AND' requires both terms to be 'TRUE' for the resulting value to become 'TRUE', otherwise it returns 'FALSE'.
'NOT (TRUE AND FALSE) AND TRUE' now becomes 'NOT FALSE AND TRUE'. The Boolean operator 'NOT' will return the opposite of the term given, so 'NOT FALSE' becomes 'TRUE'. This leaves us with 'TRUE AND TRUE' which returns 'TRUE'.
2. <u>'NOT (TRUE AND TRUE) AND TRUE':</u>
'TRUE AND TRUE' inside the parentheses will result in 'TRUE', leaving us with 'NOT TRUE AND TRUE'. 'NOT TRUE' will give us 'FALSE', resulting in 'FALSE AND TRUE'. The resulting value of 'FALSE AND TRUE' is 'FALSE'.
3. <u>'NOT (TRUE AND TRUE) OR TRUE':</u>
Again, 'TRUE AND TRUE' inside the parentheses will result in 'TRUE', leaving us with NOT TRUE OR TRUE'. The Boolean operator 'OR' requires only one term to be 'TRUE' for the resulting value to become 'TRUE'. This means that this statement will return 'TRUE'.
Hope this helps :)
