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.

Most managers see inappropriate dressing every day. Some are left angered while some are confused as to what is the right way to approach such situations. What follows next needs to be professional oriented. Being the manager, I would start by finding out what the appropriate dressing policies are. Some companies might have dress code policies while others might not. Assuming that this company has, I would read these policies carefully. The next thing that is required from me is to have a small conversation with the employee discretely. As professional as I can be, I will mention how I feel his or her dress code is inappropriate and try to summon the employee by asking him or her whether they are fully aware of the appropriate dress code. I will try to agree with the employee on what is appropriate and what is not. If we agree, requesting the employee to home and change clothes is unnecessary, but if the need to do that arises, I would consider that to be an option.
