Chapter -5 Networking and Server
Introduction of Network – A computer network consists of two or more computing devices connected to each other to share resources and information called a network.
- The network becomes a powerful tool when computers communicate and share resources with other computers on the same network or entirely distinct networks.
- Computers on a network can act as a client or a server.
- A client is a computer that requests for resources.
- A server is computer that controls and provides access to resources.
Why need of network-
- A computer that operates independently from other computers is called a standalone computer.
- The processor transferring data from one system to another using various storage devices is called sneakernet.
Classification-
LAN, WNA, and MAN are the basic types of classification of which LAN and WAN are frequently used.
Local area network (LAN):
- A LAN covers a relatively small area such as a classroom, school, or a single building.
- LANs are inexpensive to install and also provide higher speeds.
Metropolitan area network (MAN)
- A MAN spans the distance of a typical metropolitan city.
- The cost of installation and operation is higher.
- MANs use high-speed connections such as fiber optics to achieve higher speeds.
Wide area network (WAN)
- WAN span a larger area than a single city.
- These use long distance telecommunication network for connection, thereby increasing the cost.
- The internet is a good example of a WAN.
SERVER-BASED:
- A Server-based network offers centralized control and is designed for secure operations.
- In a server-based network, a dedicated server controls the network.
- A dedicated server is one that services the network by storing data, applications, resources, and also provides access to resources required by the client.
- These servers can also control the network’s security from one centralized location or share it with other specially configured servers.
Server- The server is used to manage client-based operating system also say that server is used to manage all computer.
Server OS-
- Window 2000
- Window 2003
- Window 2008
