NETWORKING AND OPEN STANDARDS
 
Network: A Computer Network is a number of computers (Usually called terminals
 
interconnected by one or more transmission paths.
 
Need of Networking:
 
1. Resource Sharing
2. File and data sharing.
3. Data security and centralized security
4. High Reliability :
5. Communication Media

Application of Networks
 
1. Sharing of data, services and resources
2. Access to remote database
3. Communication facilities
 
Elementary Terminology of Networks :
 
1. Nodes (Workstations):- The term nodes refer to the computers that are attached to a network and are seeking to share the resources.
2. Server:- A computer that facilitates the sharing of data, software and hardware resources on the network
3. Network Interface Unit (NIU) or NIC:- An interpreter that helps establish a connection between the servers and workstations.
4. MAC Address:-It refers to the physical address assigned by NIC manufacturers.
 
It is a unique 6 byte address separated by colon where first three bytes refer to manufacturer id and last three are card no. e.g. 10:B5:03:63:2E:FC
 
4. IP Address:- Every machine on a TCP bar IP Network has a unique identifying no. called an IP Address.
e.g.216.27.61.231
 
5. Domain Name:-It is a unique name assigned to a website. It has three parts:
i) www
ii) Name describing the website’s purpose
iii)TLD(Top Level Domain) such as .com, .net, .in, .edu, .org etc.
 
6.DNS(Domain Name Resolution):- It refers to the process of obtaining corresponding IP Address from a domain name. NETWORK TOPOLOGIES : The pattern of interconnection of nodes in a network is called Topology.
 
1) Bus Topology or Linear Topology : In this topology a single length of the transmission medium is used onto which the various nodes are attached. The transmission from any station travels the length of the bus, in both directions
and can be received by all other stations. The bus has a terminator at either end which absorbs the signal, removing it from the bus.
 
Characteristics:
 
1. Short cable length and Simple wiring layout
2. A single cable called trunk is used through which all data propagates and to which all nodes are connected
3. Easy to extend
4. There is no central point of failure on a bus because there is no hub.
5. Entire network shuts down if there is break in the main cable.
6. Terminators are required at both ends of the backbone cable.
7. Addition of nodes negatively affects the performance of the whole network.
 
2) Ring Topology: In a ring topology each node is connected to two and only two neighboring nodes. Data is accepted from one of the neighboring nodes and is transmitted onwards to another. Thus data travels only in one direction.
1. Every computer serves as a repeater to boost signals
2. Short cable length.
3. Suitable for optical fiber
4. Difficult to add computers
5. More expensive
6. If one computer fails, whole network fails
7. Data clashes can also occur if two machines send messages at the same time.
 
3) Star Topology: A star topology is designed with each node connected directly to the server via hub or switch. This topology is used in most existing information network. Data on a star network passes through the hub or concentrator before continuing to its destination.
 
1. Easy to install and wire
2. No disruptions to the network when connecting or removing devices.
3. Easy to add new station as each station has direct cable connection to hub or switch.
4. Depending on the intelligence of hub, two or more computers may send message at the same time
5. One malfunctioning node does not affect the rest of the network.
6. Required more cable length than a linear topology.
7. All signals transmission through the hub; if down, entire network down
 
4) Tree Topology
A tree topology (hierarchical topology) can be viewed as a collection of star networks arranged in a hierarchy. This tree has individual peripheral nodes (e.g. leaves), which are required to transmit to and receive from one node to other node and are not required to act as repeaters or regenerators. Unlike the star network, the functionality of the central node may be distributed. As in the conventional star network, individual nodes may be isolated from the network in case of failure, if a link connecting a leaf fails, that leaf is isolated. If a connection to a non-leaf node fails, an entire section of the network becomes isolated from the rest.
