Answer:
Hi, for this exercise we have two laws to bear in mind:
Morgan's laws
NOT(А).NOT(В) = NOT(A) + NOT (B)
NOT(A) + NOT (B) = NOT(А).NOT(В)
And the table of the Nand
INPUT OUTPUT
A B A NAND B
0 0 1
0 1 1
1 0 1
1 1 0
Let's start!
a.
Input OUTPUT
A A A NAND A
1 1 0
0 0 1
b.
Input OUTPUT
A B (A NAND B ) NAND (A NAND B )
0 0 0
0 1 0
1 0 0
1 1 1
C.
Input OUTPUT
A B (A NAND A ) NAND (B NAND B )
0 0 0
0 1 1
1 0 1
1 1 1
Explanation:
In the first one, we only need one input in this case A and comparing with the truth table we have the not gate
In the second case, we have to negate the AND an as we know how to build a not, we only have to make a nand in the two inputs (A, B) and the make another nand with that output.
In the third case we have that the OR is A + B and we know in base of the morgan's law that:
A + B = NOT(NOT(А).NOT(В))
So, we have to negate the two inputs and after make nand with the two inputs negated.
I hope it's help you.
Answer:
(B) A single public IP address that it can use for NAT
Explanation:
Because the IPV4 IP protocol is still used today, the number of available IP addresses is limited (only 4,294,967,296 addresses in the world), for this reason, the most correct practice is the assignment of a single public IP to those companies that acquire services from an ISP, with some few exceptional cases of companies that own several.
So that the company's addressing can be executed successfully, the use of NATs is enabled, this allows the translation of network addresses, allowing the company to have as many private networks as necessary and that these can be communicated Correctly with the global network, the Internet, through the public IP of the company.
Answer:
B. Internet of things.
Explanation:
Internet of things (IOT) is an interconnection of everyday devices through the internet to allow the device send and receive data. It is used for remote connections in offices, homes and industries to achieve various activities like switching of the power status, regulating device operation etc, in the absence of a physical operator.
BYOD or bring your device to work is a situation where members of an organisation connect and use their personal devices in the company's private network.
Answer and Explanation:
import Circle
#include<conio.h>
void main ()
int t , length , n
//for hexagon
def hexagon(t, length, n):
for _ in range(n):
t.fd(length)
t.lt(360 / n)
square = Circle.Circle()
square.penup()
square.sety(-270)
square.pendown()
hexagon(square, 30, 60)
While proceeding with an internet search I find google to be the best source considering its high accuracy. When asking your question keep it minimal yet descriptive. After having found a few sources cross reference them with each other and throw out any sources that may hold false information. After having narrowed them down look to see how recent they are because since their publication new information may have been brought to light. Look to see if they have links to where they got their information. All in all just be diligent.
