This is also the type of LAN technology in which main internet cable is attached to one server and distributed amoung attached computers by the operating system. In offices and net cafes, we can see that one internet connection is shared between all computers. For example movies and songs can be stored on the server and can be accessed by any authorized user (Client computer). If any computer (Client) needs data then that computer user can simply log in and access the data from the server. So there is no need to purchase separate resources for each computer and it saves money.Īll the data from attached computers can be stored in one server. Types of resources are the DVD drive, printers, scanners, modems and hard drives. So same department computers can communicate with each other but different department computers cannot communicate with each other.Īll the resources are attached to one network and if any computer needs any resources then it can be shared with the required computer. All the computers of these departments are logically connected to the same switch but one department computer cannot access another department computer.
For example, there are different departments in the office like the accounting department, support department, and administrative department.
This type of network is used to logically differentiate and limit the different level of computers. In a virtual area network, different switches of LAN are logically connected to each other to make the single switch. What is a virtual local area network (VLAN)
