Answer:
MAC Addresses (Destination and Source MAC address)
Explanation:
A switch has 3 primary functions:
- Forward frames
- Learn addresses
- Avoid loops
An Ethernet frame has the header, data and trailer and there are two specific fields in the header that helps the switch to know where to send data in future transmissions.
- destination MAC address
- source MAC address
every Ethernet frame has this and when the frame hits a switch or any device, any device can look at it ( an Ethernet frame ) and know where it is suppose to go and where it came from.
Every switch has a MAC address table where it stores MAC addresses of different computers on the network.
Example:
When a PC1 sends a frame to PC2 through a switch, the switch looks at the header of the Ethernet frame for the source mac address and adds the source MAC address to its MAC address table and also the port that it came through.
simply put:
A switch looks at the source MAC address to see if it knows it already, if it does. Great! no need to add it again to it's address table.
If it doesn't, it adds it's source address and the port that the frame came from.
This basically how the switch populates its MAC address table.

The answer is below.
Explanations:
maintain the affairs or rules of conduct of the company, including both the employer and the employees.
The Policies and procedures set by companies will clearly state the responsibilities and duties of both employer and employees, which eventually serve as a means of protecting the interest of all the parties involved in a company.
I don’t know if this supports all, but try lenntech, duckters, and I will add on later
Answer:
Explanation:
Given
Required
The result when 
and 
Analyzing the given instruction
a*=(++a)/(6)+(b++3)
Single out and solve the expressions in bracket
(++a) = a -- When the ++ operator appears before an operand, it is called pre increment. meaning that the operation will be done before the operand will be incremented.
So: in this case: ++a = a
The operator, as used in that statement is the same as: b + 3.
So:
The above expression is calculated as:
So:
An array data type is similar to the structure of a row in a database table.
