Answer 1

Answer)

Answer 2) Some of the malware forms are as follows:

Worms which lead to spreading in the software as vulnerability and phishing attack

Adware is also a way of malware which automatically delivers the advertisement where most of the free version of the advertisement is bundled with the software.

The bug is a flaw in the system which gives an undesirable result or outcome. It occurs because of human error and marks its existence because of source code or the compilers of the program

Ransomware is another kind of malware which holds the computer system while demanding the ransom where the user access is restricted

The rootkit is considered as the type of malicious software which was designed for remotely accessing the computer system without even being detected by any user or any of the security programs. Once this gets installed then there is no modification that can be done.

Spyware is where the type of malware where the function which would spy on the other functions or the user activity without notifying them.

Some of the other examples are Virus, Trojan horse, worms etc

Answer 4)

Difference:

TCP is reliable yet a little slow and most are used for the email and web browsing and are unicast by nature. This is a connection-oriented protocol and is meant for highly reliable and transmission timeless and critical activity. The header size is 20 bytes. It also rearranges the data packet in the order specified.

The UDP is not reliable but can be used for broadcast, unicast and multicast and is associated with the type of application like the VOIP and music streaming. The header size for UDP is 8 bytes. Used for efficient transmission, and for faster application. This is not connection-oriented. This is meant for message transfer and transport.

Similarity:

Both of these are the protocol meant for message transfer and transport.

Both of them have access to unicast transmission.
