Answer:
High-gain and directional wireless antenna.
Explanation:
WiFi can be defined as a wireless local area network that allows network devices such as access points (APs), computers (both laptops and desktops), smartphones, smart televisions, etc., to communicate with each other wirelessly over a short-ranged network. It is a standard communication network that uses radio waves to establish a channel (medium) between multiple network devices.
This ultimately implies that, the network range or distance covered by WiFi is largely dependent on transmission power and frequency. Generally, the standard range or distance covered by WiFi is about 50 meters (160 feet).
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver through the use of an antenna.
In this scenario, you need to implement a wireless network link between two buildings on a college campus, which are 100 meters apart.
A high-gain antenna is an electromagnetic device that typically has a gain rating of 12dBi or sometimes higher. Also, a highly directional antenna can only receive radio signals from a specific direction and it compresses the radio waves that are being transmitted from a sender in to a very narrow beam.
Hence, the two (2) type of wireless antenna you should use on each side of the link are a high-gain antenna and a directional wireless antenna.
1. Using VPN : Using VPN changes the IP address of your computer, changing the server for VPN again and again will change the IP and thus the omegle may suspect you as a robot or someone trying to load their server traffic and thus their algorithm banns it.
2. Leaving the account logged in : Sometimes when we shut a laptop from a friends house or another computer in house we leave the account logged in and thus if the account is logged in more then 5-6 times the server may think that the account is being used by someone else and thus banns it.

How to make a comparison chart?
Answer:
5400
Explanation:
- As there are three spaces to be filled. First can have any alphabet, but not i and o. And there are 26 alphabets so, only one out of 24 can be filled in the first blank.
- In the second blank any alphabet can be used, but not the one same as the first one so we can choose from the remaining 25 alphabets.
- In the last blank any number can be chosen, but not 0 so we have 9 options to choose from.
Finally,the number of options available is <em>24*25*9 = 5400</em>. So, 5400 license plates can be made using these combinations.
