The command is Merge & Center
This command could be easily found in the toolbar of your excel.
If you execute this command in two different cells, those cells will be merged into one larger cell and the content in that cells will be placed exactly in the middle of the combined cell (measures according to combined cells' length)
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 ⇒

C. OS hardening.
Making an operating system more secure. It often requires numerous actions such as configuring system and network components properly, deleting unused files and applying the latest patches.

Based on the contextual situation, the cable stations across the country from 8:00 p.m. to 10:00 p.m., or during <u>Late-fringe time</u>.
<h3>What is Late-Fringe Time?</h3>
