Computer (Part-3)

HTML stands for HyperText Markup Language. It is the standard markup language used to create and design web pages. HTML provides the basic structure of a web page, which is enhanced and modified by other technologies like CSS (Cascading Style Sheets) for styling and JavaScript for interactivity.

HTML uses a system of tags to define elements on a page, such as headings, paragraphs, links, images, and other content.

TCP stands for Transmission Control Protocol. It is one of the main protocols of the Internet Protocol Suite and is used for transmitting data over a network. TCP is responsible for ensuring reliable, ordered, and error-checked delivery of data between applications running on hosts communicating over an IP network. It establishes a connection between the sender and receiver before data transmission begins, and it manages the flow of data to ensure that packets are delivered in the correct sequence and without errors.

A worm is a type of malware that can spread and replicate itself, often without user interaction. It does not require a host program to spread, unlike a virus. Worms use network connections to find vulnerable devices and systems to infect, and they can spread rapidly. Unlike viruses, which need to attach to another program or document, worms are self-contained and can operate independently.

The generally recognized phases of a computer virus include:

1. Dormant Phase: In this initial stage, the virus is inactive. It has managed to enter the system but is not yet doing anything malicious. It might be waiting for a specific trigger, like a certain date, a particular program being run, or a specific user action.
   
2. Propagation Phase: This is when the virus starts to replicate itself. It copies its code and attaches it to other executable programs or system areas on the infected computer. In some cases, it might also spread to other computers on a network.
3. Triggering Phase: The virus activates and its malicious payload is unleashed. This could be caused by a condition specified during the dormant phase being met.
4. Execution Phase (or Payload Phase): This is when the virus performs the harmful actions it was designed to carry out. These actions can range from displaying annoying messages or slowing down the system to more severe consequences like deleting files, corrupting data, or providing unauthorized access to the system.

Therefore, any of these phases – dormant, propagation, triggering, or execution – would be considered a valid phase of a computer virus.
