Answer:
Interference of signal and the range between the user and the access point.
Explanation:
Elevators, specifically those with high voltage, are notoriously known for being a source of very strong magnetic fields. They produce a lot of harmonics that causes signal interference and noise. Whenever there is any kind of noise in a network, it causes huge intermittent connection. Also, the farther away the user is from the router or the AP, the weaker the signals and the more the intermittencies. The user is recommended to be within the edges if the range limit.
Answer:
C. Inaccurate and misleading data can be more easily disseminated to scientific researchers.
Explanation:
The above one is certainly the correct option. We know these kinds of the database as an open database, and these are available for all on the internet. The best example is the World Bank database, Census.org is also a good example. All these databases are a huge collection of data sets with meaningful data. The inaccurate and misleading data is never thought to be spread among the scientific researchers easily as it is not good for research, and requires a huge level of data cleaning. Hence, C. is the correct option here as it is not an advantage.
Answer:
DNS poisoning
Explanation:
DNS is a server service that verifies or resolves an IP address to a site or domain name. It's services is made available with a dhcp request from a client system, providing the ip address of the DNS server. The DNS server has the records of domain name linked to their individual ip addresses.
When an attacker wants a client to visit his site without knowing the site is not genuine, he gains access to the dns server and changes the information or poisons the entries of the server. So if the client tries to access that site, it takes him to the attackers site. This is called DNS poisoning.
Computers can be used for numerous things haha for one, research, games, connection from distances, and homework.
