Technology

Especially in companies and in the era of information transfer, it is necessary to quickly exchange data via the internet and wireless connections with the LAN. You need to carefully consider the placement and configuration of your wireless network, and then its administration to make it stable, fast, efficient, and secure. What is LAN, WAN, VLAN, and WLAN management?

What is LAN?

The LAN network enables communication and sharing of virtual resources between computers, servers, and network printers. It is a necessary solution for companies that significantly improve the operation of an enterprise that works with the use of computers and other office tools connected to the network.

LAN management is the process of properly adjusting and installing network devices, as well as monitoring them.

Thanks to the LAN, you can connect your local network to this wide-area WAN. A LAN network can also be designed at home, not only in large companies.

What are WAN, WLAN, and VLAN?

Wi-Fi defines the entirety of computer wireless networks, but this concept is not entirely precise.

WAN – Wide Area Network, i.e. an extensive computer network that extends beyond the area of one city. WAN connects through devices located in different geographic areas. Uses a variety of serial transmissions. In short – this is Internet access, in routers, we connect the Internet to a port called WAN.
WLAN – Wireless Local Area Network, i.e. a wireless local network that connects via network cards, access points, antennas, terminals. There is a wireless network to which phones, laptops, tablets, TV, WiFi speakers, consoles, etc. connect.
VLAN – Virtual local area network, i.e. a virtual local area network is a logically separated network within another larger physical network. It is used to separate different parts of the network, such as Corporate from Guests and DMZ.

How to install and configure network devices?

Initially, you need to consider a concept that will suit the size and scope of your business. The network administrator must become familiar with the equipment available in the company and find out how many people will use it. This will facilitate the creation of deployments necessary for the proper functioning of the LAN. The IT administrator is responsible for connecting the necessary equipment, its configuration, but also monitoring and, if necessary, solving emerging problems (also via remote mode). All activities aimed at the proper management of LAN, WAN, and WLAN networks begin with the installation and configuration of WAN routers.

Firewall installation and configuration – security is one of the most important issues in companies that exchange sensitive and protected data with each other. Therefore, it is important to remember about security measures, such as firewalls, when managing and configuring networks. It controls data transmission, allows you to block pop-ups on websites, stops certain pages, and manages cookies. The installation and configuration of the firewall depending on the selected program.

Installation and configuration of the LAN router – a switch is a device that allows you to divide the network into managed and unmanaged. It allows you to separate channels, which increases network security because with the help of a switch you can define access and divide it into individual accesses. The managed switch is available to the network administrator. The switch can be configured using a web browser or using the telnet console (unencrypted channel), SSH (encrypted channel), serial (physical cable).

Network management - what is it?

For years, I T Leader has been supporting many companies in creating and configuring local networks that are to accelerate and improve work in the company. Proper administration is essential for this. A properly implemented and configured LAN network will be safe and functional for employees. Stabilizing the network and creating a swap space is one of the tasks of the network administrator. The second is managing, configuring, and fixing any shortcomings. The administrator’s tasks include managing:

efficiency,
configuration,
access,
devices,
events,
security,
liquidity,
shortcomings.

Management is possible in remote mode. An IT specialist does not need to be physically on-site to correct any LAN malfunctions.

It is important to monitor the network and react quickly to any problems that arise. Network security is a guarantee of not only stability but also security. Enterprises must not be exposed to data loss as this could have catastrophic consequences. Therefore, it is important for the network administrator to monitor logs and control events.

It is equally important to periodically update the software of network devices and operating systems. Such an improvement to the latest version allows you to secure the network, and also makes the devices and tools connected to it work faster and more efficiently. Upgrading is also an important process for home computers that are connected to the network.

Connection failure and LAN interruption are not always caused by an internal error. Sometimes the cause of the defect is a failure on the part of the internet provider. Therefore, the network administrator should cooperate in this area with internet connection and fiber optic providers, as well as with producers of network equipment. In the event of a fault, it can contact the source directly.

Administration and management of networks

Companies operating today also depend on the proper functioning of technology and on a properly established, administered, and managed IT infrastructure. A LAN that connects computers, drives, and devices are essential to helping your business run better. In IT Leader, we will create a stable and, above all, safe network that uses LAN, WAN, and WLAN connections. In addition, we will monitor its operation, configure, update and correct any failures. With the use of dedicated tools, we will create a safe network to manage the IT infrastructure within the enterprise.
