• File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from
a server to a client on a computer network.
• FTP is built upon a client–server model architecture using separate control and data connections between the
client and the server

The main purpose of FTP is to facilitate the uploading and downloading of files between computers. It’s often used
for tasks such as
• Uploading website files to a web server.
• Downloading software updates from a remote server.

• Sharing files between users on a network.
• Backing up files to a remote server.
Advantages of FTP
Speed - One of the biggest benefits of FTP is speed. The FTP is one of the fastest way to transfer files from one
computer to another.
Efficient: It is more efficient as we do not need to complete all the operations to get the whole file.
Security -To access the FTP server, we need to login with username and password. So we can say that FTP is
more secure.
Back & forward movement - FTP allows us to transfer the files back and forth. Suppose you are a manager
of the company, you send some information to all the employees, and all of them send information back on the
same server.
Disadvantages of FTP
• File size limit is the drawback of FTP only 2GB size files can be transferred.

• Multiple receivers are not supported by the FTP.
• FTP does not encrypt the data this is one of the biggest drawbacks of FTP.
• FTP is unsecured, we use login IDs and passwords making it secure but they can be attacked by hackers.
E-mail
A way of sending electronic messages or data from one computer to another.
A worldwide e-mail network allows people to exchange e-mail messages very quickly

Email, short for “electronic mail,” is a method of exchanging digital messages over the Internet.
It allows people to send and receive messages and files to and from each other using electronic devices such as
computers, smartphones, and tablets.

Email has become one of the most common and widely used forms of communication both in personal and
professional contexts.
DNS

DNS stands for Domain Name System, and it is a fundamental technology used on the Internet to translate
human-readable domain names into IP addresses.
Computers and servers communicate with one another using IP addresses, which are numerical identifiers for
devices on a network.
However, remembering and typing the IP addresses for every website you want to visit would be impractical for
humans.
DNS acts as a distributed directory system that allows users to access websites and other online resources using
easily memorable domain names (like www.example.com) rather than numerical IP addresses.
