BINARY CODE USES WHICH 2 NUMBERS?
- A.
1 & 2
- B.
0 & 1
- C.
0 & 2
Correct Answer
B. 0 & 1Explanation
Binary code is a system of representing information using only two digits, 0 and 1. In this system, 0 represents the absence of something and 1 represents the presence of something. Therefore, the correct answer is 0 & 1, as these are the two numbers used in binary code.Rate this question:

Which is faster gigahertz or megahertz?
- A.
Megahertz
- B.
Gigahertz
Correct Answer
B. GigahertzExplanation
Gigahertz is faster than megahertz. Hertz is a unit of frequency, and both gigahertz and megahertz represent billions and millions of cycles per second respectively. Since gigahertz has a higher value, it means that it can complete more cycles in a second, making it faster than megahertz.Rate this question:

Which binary code represents the number 3
- A.
00000011
- B.
11000000
- C.
00010000
Correct Answer
A. 00000011Explanation
The binary code 00000011 represents the number 3 because in binary, each digit can only be a 0 or a 1. The leftmost digit represents the value of 2^7, the next digit represents 2^6, and so on. In this case, the rightmost digit is a 1, representing 2^0, and the second rightmost digit is also a 1, representing 2^1. Adding these values together (2^0 + 2^1) gives us the decimal value of 3.Rate this question:

Which of the following is an example of a input device?
- A.
Speakers
- B.
Printer
- C.
Mouse
- D.

Binary code does not work on all computers?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Binary code is the fundamental language that computers use to process and store data. It is a universal language that all computers understand, regardless of their architecture or operating system. Therefore, binary code works on all computers, making the statement "Binary code does not work on all computers" false.Rate this question:

Binary code is a 10 base system?
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Binary code is not a 10 base system. It is a base 2 system, meaning it only uses two digits, 0 and 1, to represent all numbers and characters. In contrast, a 10 base system, also known as decimal system, uses ten digits, 0 to 9, to represent numbers. Therefore, the statement that binary code is a 10 base system is false.Rate this question:

A main frame (super computer) ...
- A.
Fits on a desk
- B.
Takes up an entire room
- C.
Takes up part of a room
Correct Answer
B. Takes up an entire roomExplanation
The correct answer is "takes up an entire room" because mainframe computers are large and powerful machines that require a significant amount of space to accommodate their size and cooling requirements. They are typically housed in specialized rooms or data centers due to their physical dimensions and the need for proper ventilation and infrastructure. Therefore, they cannot fit on a desk or take up only part of a room.Rate this question:

A PC (personal computer) can be used by how many users at one time?
- A.
One
- B.
Hundreds
