The best description of a computer virus is. Someone first starts out making a malicious program, then can send it to a unexpected user. After that, when the user opens the malicious program, it can do negative things on the target. The virus first starts out in the system32, then infects a random file type for example, exe files, or dlls etc. Then random errors can pop up on the computer saying "YOUR COMPUTER IS UNDER RISK! CALL THIS NUMBER NOW! 555-555-5555" and the options of the error, can direct you to a website, that can give you another virus. To get rid of a virus, you have to ignore the popups that comes onto your computer, and get a strong antivirus like avast, or avg. Then let it scan the system. After when the scan is done, it will show up the virus, and it will give you options "to delete virus or ignore it" you would hit delete. I hope this answer helped you. Let me know if you have any more questions! Thanks!

Data transmission using TCP is 1 MB/s. It takes [(232 1) 7000] / 1,000,000, or 4295 seconds, for the sequence number to go back to zero.
A communications protocol known as Transmission Control Protocol, or TCP, permits message transmission between computer hardware and software via a network. It is designed to transmit packets across the internet and to guarantee the successful transmission of data and messages over networks.
The Internet Engineering Task Force (IETF) has designated TCP as one of the foundational protocols that serve as the rules for the internet (IETF). One of the most extensively used protocols in digital network communications, it offers end-to-end data delivery.
Before being delivered between a server and a client, data is first structured by TCP. It guarantees the correctness of data sent through a network.
