Network, in its most general definition, is a communication and interaction network. It can be done easily with all kinds of communication networks and it gives trouble-free results. It is an undeniable fact that most individuals and communities in the world are members of any network. While the individual network is concentrated in areas such as social media, the collective network is preferred by companies and large companies. A network is a large mesh that drives the sharing of content, location, and information that individuals and communities can access instantly. While the contents are sometimes realized in line with personal needs; sometimes it is driven by a community's request for information and data transfer.

Function of Network Devices

The most valuable medium for network devices is the area created by communities and companies. Due to their large structures, companies need instant, fast and high quality data transfer. In the global age, it is vital to navigate the dense data. The function of network devices is to increase the coordination and cohesion of companies. Intense information flow is extremely important for healthy communication with customers. The first step of healthy communication is defined as a strong network and infrastructure. Network security is very important. The importance of network devices has a key place here. The stronger the network infrastructure in a workplace, the higher the rate of profit and efficiency. The gained stability line is successfully maintained. This line of stability reached is the most important factor of growth and development. As with every operating system, network systems also have key devices. These devices support all this positive progress and increase efficiency. Network security is a very important issue in this area. Institutions work overtime to avoid this problem in their business. Network security should be performed with known and efficient devices. It is recommended that these devices are carefully selected by institutions.

Hub

Hubs occupy a key place in the network. It increases the possibilities of computers to share from server to server. Making contact from one computer to another with hubs is known as the preferred and popular method. There is only one defect observed in hubs. The current defect of the system is that the network breaks down and fails when there are more than one server at the same time. Although hub technology is widely used today, it can be shown as an old and less effective device. The importance of network devices is important in communication as well as in security.

Switch

Switch is shown as a more useful and advanced technology network device compared to Hubs. The use of switches provides the institutions high maneuverability and performance gain in network networks. Another important effect of this device is the independent communication channel it offers to each computer. When more than one user comes together on switches, there is no problem. This device, which can host more than one user, is known as the most important example of healthy interaction.

Repeater

The network power of repeaters is quite strong compared to other devices. It is one of the favorite devices of many institutions with the high performance it offers to users. Repeater optimizes the system to the network by revising and updating the Ethernet packets it is connected to. If deformation or deterioration has occurred in the packages found, it eliminates these problems and increases the quality.

Bridge

Bridge is also known as bridge device. Connecting two TCP/IP devices, this system also controls physical connections. In addition to its superior capacity in its physical connection, data flows in the network are under its control. It receives incoming data by processing it without any problems. If the processed data is correct and problem-free, it completes the last step by making the necessary directions. The importance of network devices continues to come to the fore with the ease provided.

Router

Routers stand out as a more functional device than Bridges. It is known as the most preferred system of professional works with the ease it creates in routing tools. It can route over the LAN used by a user to other LAN points or WAN users. This system, which does many important works, is the favorite of institutions. Another explanation for its diversity and high efficiency is that the device has its own operating system.

Firewall

How to ensure network security with Firewall? Firewall is a known security operating system. Firewall is used at individual points as well as in corporate places. Firewall's function is quite simple and important. It controls the system security requirements standing between the local network and the external network. Its function is to filter and direct the incoming data according to the criteria given by the users. When users tell the device the data criteria they want, the firewall operating system manages and directs this data with the specified principles.
