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 Feature that can control left and right indents on using markers is Ruler. The indent marker consists of two triangles and a rectangle. <span>To change the left indent, click on the very bottom of the indent marker, the rectangle, and drag it to a new position.</span> <span>The Right Indent is indicated by a single triangle on the Ruler at the current right margin.

Answer:
The answer is "Fiber Optic Cable".
Explanation:
In the given question options are defined, but in these options, there is some error.
The optical fiber cable is also known as internet wiring, which includes fiber strands inside an isolated housing. It is used to transferring data at a very high speed. This cable is developed for long-range data networking, high-performance connectivity, and multimedia, and other choices are wrong that can be described as follows:
- A modem is used to transmits data over a network, that's why it is wrong.
- Router is used to transport traffic between your computer and the internet, that's why it is wrong.
Answer:
Company WAP has SSID broadcast disable
Explanation:
Disabling SSID broadcast will make your WLAN network name invisible to other users. However, this only hides the name, not the network itself. that's why the user cannot find the company WLAN on her computer but yet can connected to the company WLAN and can browse to multiple websites with no problem from their company-assigned laptops.
