1. Types of network topologies:
If you, as the network manager of an organization or company, are going to network the computer systems of that department so that the systems can use resources in a shared manner, you need to choose the type of network topology for communication between the systems. There are important factors in choosing a network topology, which you should consider for your work and choose the right topology. One of the important factors in choosing a network topology is security and its setup cost, so it is better to consult the ITech network support before choosing.
The way computers are arranged or placed inside the network and the way they communicate, as well as the design of placing equipment in the network, is called network topology.
Types of network topology are:
Bus topology
Star topology
Ring topology
Hybrid topology
wireless topology
Mesh topology
Tree topology
2. Types of network protocols:
There are different types of communication protocols that play a fundamental and key role in the communication between various devices in computer networks. Each of these main communication protocols is listed below:
Hypertext Transfer Protocol (HTTP)
Hyper Text Markup Language (HTML) convention
Simple Mail Transfer Protocol (SMTP)
POP contract (Post Office Protocol | POP)
Internet Message Access Protocol (Internet Message Access Protocol | IMAP)
File Transfer Protocol (FTP)
Transmission Control Protocol (TCP)
Internet Protocol (IP)
Point-to-Point Protocol (PPP)
Definition and application of various types of computer networks
A network is a group of people or objects that can share information with each other and communicate with each other. But what is meant by network in the field of information technology. Computer networks or so called Network is a collection of computer systems, hardware and software related to the network and communication equipment such as network cables or wireless equipment. The network is generally divided into two parts: hardware (Passive) and software (Active).
Some of the passive equipment are: types of cables, connectors, network sockets, racks, etc.
Network history
If we want to look at the history of computer networks, we can point to the late 1960s, in these years, the US Department of Defense launched its advanced research agency to compete with the Soviet Union’s satellite activities. The name of this research agency was Arpa. This agency was carrying out very important research projects in the strategic and defense fields, one of these projects was the creation of strong communications in times of possible wars.
For this purpose, the first computer network was set up between four computers, two of which were located at MIT, one at the University of California, and the other at the Stanford Research Center. This was the Arpant network.

What is the work of the network?
A computer network is responsible for establishing communication between systems so that users of that network can share data and equipment with each other.
In response to the question of what is the use of the network, it can be said that by setting up computer networks, communication between systems is established and network users can share data and devices such as printers with each other.
Also, IT managers can easily manage a large number of computers and apply their policies, although these are not the only advantages of computer networks or the only purpose of computer networks.
Common terms of computer networks
In the following, we will examine common terms and expressions in the network world.
What is your client?
Client refers to a system that has a request and this request is processed and sent to the collection server. For example, when you are connected to a network with your computer and use it, your system is a kind of client.
What is a server?
Server refers to an always-on computer that has high hardware and software capabilities and provides services to clients as a central computer. It is worth mentioning that both the client and the server have their own operating systems. In client-server networks, the computers are independent of each other in addition to being connected to each other, meaning that if a computer or digital device connected to the network turns off or leaves the network for any reason, the network remains intact. But if the server goes out of service, the services it provides will also be unavailable and it will disturb the network routine.
What is a host?
Host, any device or system that is connected to the network and provides services or uses services within the network. With this definition, both the client and the server are considered hosts.
What is the use of the network?
Regardless of the physical distance, computer networks can easily support 2 computers or an organization with 2 million computers or more. have access to resources and data or make audio and video calls with each other. Files, files, hardware, software, etc. are shared in the network and users can use them based on their access level.
Types of computer networks
In this section, we want to examine the types of computer networks based on their size and extent:
What is PAN or Personal Network?
PAN stands for Personal Area Network and is the smallest type of network. Personal networks include a limited number of computers and digital devices that are several meters away from each other and are connected to each other wirelessly or wirelessly.
For example, when you have connected your mobile phone to the computer via Bluetooth, you have formed a personal network or PAN.

What is LAN or Local Area Network?
LAN stands for Local Area Network, which is called a local network. Such networks usually have high speed and can be implemented in environments with limited capacity such as a small company or building. One of the technologies used in this type of network is Ethernet technology.
Definition and application of various types of computer networks
What is MAN network or urban network?
MAN stands for Metropolitan Area Network and has the extent of a city or a large area within a city. For example, connecting the branches of an institution to other branches in the urban area is an example of a MAN network.
What is a WAN or wide area network?
WAN stands for Wide Area Network, which is created by connecting several LAN networks. Such networks are usually used between cities, countries or even continents. For the internal connections of WAN networks, ISPs and telecommunication infrastructures should be helped. The technologies used in this type of networks can be mentioned as ISDN-MPLS-ATM, etc.
What kind of network is Gan?
GAN, or global network, is short for Global Area Network, and it is said to be global wide networks that do not have geographical limitations.
What is a wireless LAN?
WLAN stands for Wireless Local Area Network. One of the advantages of such networks is that users can move around and there is no need for physical connection. Among the standards of this network, we can mention the 802.11a standard.
