Types of protocols

User Data Packet Protocol

User Datagram Protocol (UDP) is one of the oldest protocols used to transfer data over the Internet, like TCP, but UDP is more efficient in transferring data packets quickly and without delay. This is because this protocol continues to send data without Check for errors During the transmission process, which makes it suitable for sending data packets for real-time applications.^[٣]

The User Data Packet Protocol is used in live streaming and online gaming, and although this protocol is fast in transferring data, it is not suitable for sending data packets that must be verified to arrive completely and without any packets being lost.^[٣]

Internet Protocol

Internet Protocol (IP) is a protocol for addressing data sent over the network. This protocol uses the address of the receiving party within the data packet to be transferred to direct those packets across the different network points and then deliver them to the receiving party. Each device connected to the network has an Internet address that is distinct from any other address. This address consists of a set of numbers that form an address for a single device. Examples of these address formats include 192.168.1.2.^[٤][٥]

The Internet Protocol encapsulates the data packets to be sent with what is known as the Internet Protocol addressing system (IP Addressing), which includes the address of the device sending the packet and the address of the device receiving it. It also adds many other pieces of information to the data packet, such as the size of the packet and the duration of its stay on the network before being discarded. The data packet created by this protocol is transmitted either through (TCP) or (UDP), but (TCP) is often used with it to form a protocol known as (TCP/IP), which is considered the most widely used protocol in connecting networks.^[٤][٥]

Post Office Protocol

Post Office Protocol (POP) is a protocol for retrieving email from a specific mail server. POP3 is the primary version currently in use, due to its strong security features.^[٦]

This type of protocol is used Email from many companies The email service provider where POP allows the user to access and read his email address even when offline, by downloading the email messages via the user's device and then deleting the existing copy via the main server; therefore, email messages that use the Post Office Protocol can only be accessed through the same device at all times.^[٧]

Simple Mail Transfer Protocol

Simple Mail Transfer Protocol (SMTP) is the most widely used standard protocol for email services available over the Internet. This protocol provides the ability to send and receive email messages from one party to another based on each party's email address. It also provides the ability to send a single message to more than one address at the same time, and allows the inclusion of files or documents via emails. It also allows messages to be sent over networks outside the Internet.^[٨][٩]

File Transfer Protocol

File Transfer Protocol (FTP) is the most common way to exchange files between two computers connected to a network. This protocol is the primary means of uploading and transferring files from websites across the World Wide Web. Most of these websites include FTP built-in, while others provide free downloads for users to download data on these websites. the site.^[١٠][١١]

Hypertext Transfer Protocol

Hypertext Transfer Protocol (HTTP) is the primary protocol used across the Internet. World Wide Web, where this protocol regulates the process of coordinating website requests. The electronic procedures that website servers and browsers must follow to respond to commands issued by Internet users. When the user enters the address of a specific website with the aim of directing to it via the browser, it sends a request and command (HTTP) to the website server to bring the requested electronic page.^[١٢]

There is a specific version of the HTTP protocol, Hyper Text Transfer Protocol Secure (HTTPS), that is capable of securing the connection between the user and the web. And the location The electronic data is encrypted, which prevents hackers from modifying the data transmitted to and from the user.^[٤]

What are the protocols?

The world of technology includes a huge number of devices that communicate with each other according to specific rules and methods. These rules are known as protocols. These protocols also determine the way in which the user communicates with the devices and the way in which the devices interact with the data received.^[٤][١٣]
