Informatics is the science of information (Information
science) with a very broad scope.
Informatics studies the representation, communication, and
processing of information in artificial and natural systems. Technically, it is
the focus of info and how it is represented in (includes paper, digital
records, sounds and image), processed by (include human reasoning or digital
computation), and communicated within a variety of systems through human communication
and human computer interface.
Informatics has various aspects that encompass a number of
existing academic disciplines like AI, cognitive science and computer science.
Answer:
(A)AES
Explanation:
WPA2 (Wi-Fi Protected Access 2) is a security protocol which was developed by the Wi-Fi Alliance in 2004. It was used to replace the security protocol of WEP(Wired Equivalent Privacy) and WPA.
Unlike the previous security protocol, WPA2 uses the Dvanve Encryption Standard (AES) instead of the RC4 stream cipher. WPA3 has been developed but it is not yet widely in use.
Answer:
a; circuit-switched network.
b; No, it does not need congestion control.
Explanation:
For A;
A circuit-switched network is a better option for this application. This is because of the fact that the application is made up of long sessions with smooth data transfer capacity needs.
The transmission rate is known, and does not transmit in short intervals(short signals), every application session can have a bandwidth reserved without significant bandwidth wastage.
Also, the overhead expenses of setting up and tearing down connections are canceled out over the extensive period of running an application session.
For B;
If the packet-switched network is used, and traffic in the network comes from the said application. Even if every applications transmit one or more network connections. Still, we already know that every connection has enough transmission capacity to handle majority of the application data rates, no congestion(insignificant queuing) will happen.
This goes to say that no congestion control will be needed given such broad-based connection.
