In electronics class, we would learn about Logic Gates and their functions. A simple concept of whether electricity flows through a circuit or not is either Yes or No. All kinds of combinational circuits exist based on this principle. How many can you remember and get it right?

Electronic Gates

How many of these do you know? 

Which of this is false?

This is an OR Gate This is an AND Gate If A = 1, Output is 1 If A = 1 and B = 1, Output is 1

Which of this is false?

This is an XOR Gate If A and B are same, Output is 0 If A or B is 1, Output is 1 This is a NOR Gate

Which of these statements is TRUE?

This is a NOR Gate This is a Neg-OR Gate This is an XNOR Gate If both A and B are same, Output is 0

What Gate is this?

AND Gate NOT Gate OR Gate Neg Gate

Which of these is FALSE?

This is a NOR Gate If A and B are 0, output is 0 It can be written as ¬(AVB) It can be written as NOT(A+B)

Which of these is TRUE?

This is a NOR Gate This is an XNOR Gate Output is 0 when one of the inputs is 0 Output is 1 when one of the inputs is 0

Which of these is FALSE?

This is Neg AND Gate Output is 0 when one of the inputs is 1 Output is 1 when one of the inputs is 1 Output is 0 when both inputs are 1

Which of this is True?

This is an AND Gate This is a Neg AND Gate This is a NAND Gate This is a XNOR Gate

Which of this is True?

If one of the inputs is 0, then output is 1 Output = AB Output = A+B If both inputs are 1, then output is 0

If Output = (AB) + (CD), what all gates are used in this? 3 AND Gates 3 OR Gates 2 OR Gates and 1 AND Gate 2 AND Gates and 1 OR Gate

Got the opportunity to teach a few students about Electronic Gates earlier today and setup this Quiz for them to practice for their upcoming exams. It was refreshing change to brush up the basic concepts!

Computers are composed of nothing more than logic gates and combinational circuits!
