NOT (NOT x AND NOT y)
Explanation:
This is DeMorgan's theorem. Look that up for more details.
[tex]{\displaystyle {\overline {A\cdot B}}={\overline {A}}+{\overline {B}}} \newline \newline{\displaystyle {\overline {A+B}}={\overline {A}}\cdot {\overline {B}}}[/tex]
So

What is output by the following program?

Explanation:
I don't know what language this is, but the functions (methods) should work the same. It should change the value of n by decreasing it by 8 so the solution would be 8.
The functions (methods) should work the same. It should change the value of n by decreasing it by 8 so the solution would be 8.
When the program is to be printed?The first, print(val) will be printed, and here the value of val is 25 as set outside the function. Then the print(val) inside the example() will be printed, and here we have declared val as global and set its value to 15, And with last print as well, since the val is now global and with value 15, and hence the output will be 15. And hence the output is as above.
The execution of the program in the "for" loop will be following
For k=0
=> val=1 and sum=0+1=1
For k=1
=> val=2 and sum=1+2=3
For k=2
=> val=3 and sum=3+3=6
For k=3
=> val=4 and sum=6+4=10
For k=4
=> val 5 and sum=10+5=15
For k=5
=> val=6 and sum=15+6=21
For k=6
=> val =7 and sum=21+7=28
For k=7
=> val=8 and sum=28+8=36
For k=8
val=9 and sum=36+9=45
So, all the iterations of for loop are completed and the output is 45.
Therefore, The functions (methods) should work the same. It should change the value of n by decreasing it by 8 so the solution would be 8.

A network switch transmits data packets from one computer network to another computer network.
What is a network switch?A network switch connects devices in a network (such as computers, printers, and wireless access points) and allows them to 'talk' by exchanging data packets.
Switches can be both physical hardware devices that manage physical networks and software-based virtual devices.
A router is significantly more advanced and sophisticated than a switch. They can perform Network Address Translation (NAT), make faster routing decisions, and use routing algorithms to route data across large networks.
Routers connect multiple LANs, whereas switches operate within a single LAN.
