5. Exit.

Question 9

What is the entrance in a program?

Answer 9

The clearly specified first instruction in a computer program.

Question 10

What is control in a computer language?

Answer 10

To assess a condition.

Question 11

What is branching in a computer language?

Answer 11

A possible course of action arising from a decision.

Question 12

What is Control/Branching.

Answer 12

To assess a condition to decide between two of more courses of action.

Question 13

Which is the control and which is the branching in a IF THEN instruction?

Answer 13

IF is the control and THEN is the branching.

Question 14

What is a loop?

Answer 14

A control statement that execute its nested instruction until certain condition is met.

Question 15

What is a Counter in a loop?

Answer 15

A variable that keeps track of how many times the loop has been executed.

Question 16

What is called the the path that goes from the start point of the program to the end point?

Answer 16

The path of execution.

Question 17

What is called the main series of instructions of a program?

Answer 17

The Main Program.

Question 18

What Exit instruction of a program does?

Answer 18

To tell the computer that the program in no longer running.

Question 19

What is Data Structure?

Answer 19

It’s how the data is organized in terms of implementation.

Question 20

What is Linear Data Structure?

Answer 20

Data structure where the data is organized one after the other. A list.

Question 21

What is nonlinear Data Structure?

Answer 21

Data structure where the data don’t necessarily follow one after the other.
Ex: family tree.

Question 22

What is Abstract data?

Answer 22

Data where we are only concerned about what it is supposed to do, not about how it does it.
Ex: the brakes of a car.

Question 23

What is an operation?

Answer 23

1. Something computer is designed to do.
2. In math, process which a number is changed or handled by addition, muiltiplication, division etc.

Question 24

What is Machine instruction?

Answer 24

Bult-in actions that the CPU can perform.

Question 25

What is Opcode?

Answer 25

1. Short for Operation code.
2. Is a part of machine isntruction.
3. A set of binary numbers that specifies the exact operation to be performed.

Ex: In a machin instruction like: 0111011010, the first three digits “011” would be the opcode. This could mean “Add a number to an earlier number”. The other part could be the number to be add to the earlier number.
