Network strategies are the working procedure and different way a system can be configured when you are setting up a network in a home or in an office. The scope of networking technology are many and they are basically setting up two or more computers in a network so that they can communicate with each other and share a common device like a printer, scanner. Every company needs networking done so it is crucial for all IT technicians to know some basic networking strategies at least. The networking strategies can help them understand how computers are connected in a system. 

Different types of network 

Basically, a network can be of three types. They are LAN, MAN, and WAN.

<a href="https://searchnetworking.techtarget.com/definition/local-area-network-LAN>LAN stands for </a> local area network. This type of network can be set up by just connecting your home computer with printers and other devices using LAN or it can be used in the office to connect several computers and devices so that they can communicate with each other and also share resources. There is a special type of network called WLAN which means wireless local area network. When the devices are connected wirelessly in a network it is called a WLAN. MAN stands for metropolitan area network which is when a connection is established in a wide area like in a city. WAN stands for wide area network which is when the distance that is covered is spread across the entire world.

Intranet, Extranet, and Internet

The Intranet is a network when people are sharing a network and is restricted to only those people in the circle for use. Unauthorized access is blocked using a firewall and other technologies. An Extranet, on the other hand, is when an outsider is allowed authorization for a purpose like fixing the network or to work as a team temporarily. 
Internet we all are familiar with which by definition means a web of interconnected networks which are spread all over the world. 

Client-Server Networks

In the client-server networks basically, all the resources are stored centrally and the users of that resources are called clients. This type of network is common in organizations that want to set the access perimeter of their users. The central client server can be designed and set as the organization wants to ensure its safety and limit access to sensitive information. 

Network Virtualization

The process of combining hardware and software together into a single software-based administrative entity. Data, and the use of it can be many starting with external virtualization where an administrator can create one or more virtual networks from a single LAN. The benefits of making virtual networks can be to check the system and ensure that it is running properly. Internal virtualization means to configure a single system to run multiple virtual networks to test software on different platforms. The wireless virtualization is configuring the same system wirelessly for application testing.

Router, Switch, Hub, Firewall

We all are familiar with wireless routers that we use in our homes for connecting devices to the internet wirelessly. Organizations use more complex routers for faster speed and to ensure the security of their system. These routers are expensive and more complex to install. A Switch is a device that is connected to the router which can be turned on to let the users communicate with the router or turned off to interrupt the communication. Hub was used to connect multiple devices in a single device for sharing and connecting with each other. <a href="https://personalfirewall.comodo.com/what-is-firewall.htmlm">A Firewall</a> is used to prevent unauthorized access to any outsider and to prevent a security breach. It can be done by hardware, software or by a combination of the two.
