Answer 1

1)

a) TCP/IP stands for Transmission Control Protocol/Internet Protocol. It defines a suite of communication protocols which are used to connect devices in a network.

TCP/IP specifies the contract to decide how data is exchanged over by providing an end-to-end communications that identify how it should be broken into packets, addressed, transmitted, routed and received at the destination.

b) HTTP stands for HyperText Transfer Protocol. HTTP is basically the protocol defined by WWW to define the formatting of messages and how they are transmitted, and what actions Web server and browser show take to respond to various calls like POST, GET, etc.

c) URL, which stands for Uniform Resource Locator, is a form of URI and a standardized naming convention for addressing documents accessible over the Internet and Intranet. An example of a URL is https://www.HomeworkLib.com, which is the URL for the Chegg website.

d)

DNS, or the Domain Name System, translates human readable domain names (for example, www.HomeworkLib.com) to machine readable IP addresses (for example, 192.179.242.29).
