QUESTION 4 :-

Different types of Protocols :-

Protocols are set of rules to communicate over the internet.

These are:

• File Transfer Protocol (FTP) :-

This protocol is used to share/transfer files from one computer to another over the internet while following the defined rules of this protocol.

• Simple Mail Transfer Protocol (SMTP) :- This protocol is used to send e-mails over the internet.

• Hyper Text Transfer Protocol (HTTP) :- This protocol is used to connect to the user computer to make requests and send response as a reply to the requests made by the user.

• Hyper Text Transfer Protocol Secure (HTTPS) :- Same as HTTP but with encryption. This protocol is used to send and receive data from the user ( if submitted or requested so) but in encrypted form. So that the hackers can't modify it or even if they get it, It won't make sense to them because the data transfer between the computers are encrypted.

• Transmission Control Protocol (TCP) :- This is very helpful in communication over the internet because It helps in the breakdown of data into bits ( smallest component of data ) which then get transferred to the desired location with the help of IP Protocol.

• Internet Protocol (IP) :- The internet protocol assigns a computer a unique address which help to communicate with other computers with the help of TCP, The IP is responsible for defining the destination of data.

QUESTION 5 :-

URL serves as the location of a webpage over the www. It stands for Uniform Resource Locator.

Parts of URL :-

Usually, A URL has two parts:

• one: for defining the Protocol used. For example, https, http, ftp.
• Two: It is the address of the Resource you want to access or simple called as resource name.

The two parts are separated by a colon and two forward slashes. (i.e., :// )

For Example :-

URL : nationalbalbhavan.nic.in { Include http:// at the beginning }

Here, The Protocol used is http which is insecure therefore you shouldn't enter any sensitive information on this site because It could be stolen by hackers as the data shared between you and the web server won't be encrypted.

NOTE :- Always enter your personal details or credit card information on a trusted site and that must be using https.The second part, which is the Resource name, is nationalbalbhavan.nic.in

The Resource name part is further divided into several parts namely host, port, query, domain, e.t.c.,
