Network Security

Types of Internet Connections Now many different technologies are available to connect Internet.

When an analog signal arrives at the receiving computer, the modem then demodulates (converts) the signal back t

Network Architecture Network architecture means how the computers on the network interact and communicate with each other. It is the combined form of network topologies and mode of data transmission between the computers in the network. Generally, network architecture can be classified into two types: Client-server network Peer-to-peer network Client-server network A more common type of network is called a client server network. This type of network uses a central server and specialized network software. The server is dedicated and is only used to store files and run server tasks. The computers that connect to the server are called clients and these are the machines the company staff would use. In this network, each clients can share the processing and storage with the server. In this network, the server provides the services to the clients whereas clients request the server for services. The server should be powerful computer with greater processing speed and large st

Network Topologies Network topologies are the patterns of computers in the network. It is the physical layout of the terminals, links and computers in the network. Network topologies are several types. Some topologies used in LAN are as follows: Bus or linear topology Star topology Ring topology Mesh topology Hybrid topology Bus or linear topology In this topology, all the computers are connected to a common cable called trunk. Its each end has a terminator and the terminator stops the flow of data out of bus. In this network, if the cable breaks it affects the whole network. There is maximum chance of collision of data. Star Topology In this topology all the computers are connected to a master computer called server. In this type of network, the server controls all the other computers. This is the most commonly used topology in LAN. In this network, if the central point (server) fails, the whole network fails but the failure of one computer doesn’t affect the r

What is Network Connecting Devices The device which is used to interchange data information between the server to the workstation (client) is called Network Connecting Devices. It is also use to interchange data information between Computer Network. Repeaters The electronics device which receives a weak signal and converts it into the strong signal. Repeaters are used to extend transmissions. A repeater receives a signal and before it becomes too weak or corrupted, regenerates the original bit pattern. Repeaters operate only in the physical layer. It is layer one device. Hub Hub is a Networking Connecting Device which has many ports that connect to the server with a workstation PC.
