PROTOCOL
Protocol is a set of rules that govern the communication between the computers on a network.
Certain network protocols and standards must be followed in order to ensure that your computer
can communicate with another computer over a network.
Different types of protocols used for different operations on the Internet are:
Hypertext Transfer Protocol (HTTP): Transfers web pages and content between servers and
clients. It’s the foundation of data communication on the web.
Hypertext Transfer Protocol Secure (HTTPS): Encrypts data transferred between clients
and servers for security. Most websites use it to protect against unauthorised access.
File Transfer Protocol (FTP): Facilitates the uploading and downloading of files between
computers over the Internet. It operates on a client-server model.
Transmission Control Protocol/Internet Protocol (TCP/IP): Manages data transmission
and routing over networks, ensuring reliable communication between devices.
Post Office Protocol Version 3 (POP3): Allows email clients to download messages from a
server to a local device, usually removing them from the server.
Internet Message Access Protocol (IMAP): Allows email clients to access and manage
emails on a server, synchronising across multiple devices.
Simple Mail Transfer Protocol (SMTP): Sends email messages from clients to servers or
between servers; handles outgoing email communication.
A computer network is a group of interconnected computer systems and other computing
devices.
A server is a computer that manages and shares resources like files and programs with
other computers (called clients) on the network.
A router is a network device that connects two or more networks and manages the flow
of data between them.
Networking cables are physical cables used to connect and transmit data between
devices in a network.
Bandwidth is the maximum rate at which data can be transmitted over a network
connection or communication channel.
The layout or arrangement of computers or nodes in a network is referred to as topology.
The network architecture defines the overall design of the computer network.
Protocol is a set of rules that govern the communication between the computers on a
network.
