The logical expressions are
- (X NOR Y ) OR Z ⇒  
- (A NAND B) AND NOT C ⇒  
<h3>How to determine the 
logical expressions?</h3>
<u>Logical expression 1</u>
X and Y are linked by the NOR gate.
So, we have:
X NOR Y
The X NOR Y is linked to Z by the OR gate.
So, we have:
(X NOR Y) OR Z
Hence, the logical expression is (X NOR Y ) OR Z ⇒ 
<u>Logical expression 2</u>
A and B are linked by the NAND gate.
So, we have:
A NAND B
The A NAND B is linked to C by the AND gate.
So, we have:
(A NAND B) AND C
Hence, the logical expression is (A NAND B) AND NOT C ⇒

Answer:
Second generation computers were based on transistors, essentially the same as first generation computers, but with the transistors replacing the vacuum tubes / thermionic valves.
Third generation computers used printed circuit boards to replace much of the wiring between the transistors. This had the advantage that components could be mass produced, reducing the number of errors because of incorrect wiring and making the component boards replacable.
