If channel is taken into account as the highway, then the bandwidth is like the range of lane within the high way. More lanes propose extra traffic at a time and high speed transportation. Bandwidth also refers to as grade, tells us the charge, or speed at which proof almost naturally transmitted over the channel. There are three brands for communication channel:
1. Narrow Band Channel
For example, within the event you speak to your pal on the phone, you are the sender. The telephone line within which your voice is transmitted is the medium and your pal is the receiver. This is the straightforward example of voice communication. The same idea holds good for proof communications also. Data Communication is the function of transporting proof from one point to yet another. In this case the sender and the receiver are oftentimes machines, in sure, personal computer devices (computers, terminals, peripheral devices like line printers, teletypes, disks, etc) and the transmission medium almost naturally telephone traces, microwave hyperlinks, satellite hyperlinks, etc.
2. A medium which caries the message.
Broad band channel or the high speed channel is the fastest channel which transmits proof up to several million bits consistent with moment and in special instances, is going up to billions of bits consistent with seconds. Coaxial cable, fiber optics, and Microwave are the examples of broadband channels.
Many people have asked to see the "Big Picture" of networking: How does all the concerns. Where does Microsoft NT fit in with routers and the OSI layers? What about UNIX, Linux and Novell? The following page has a graphic showing The Big Picture. It tries to show all places of networking and how they tie into either other. The following key describes the graphical symbols used:
Voice band channel or the medium speed channel is quicker than slim band channel, and transmit proof from 110 bits consistent with moment to 9600 bits consistent with moment. Telephone traces are the example of voice band channel.
This is the maximum widely used network in organisations. A local arena network is a digital communication process in a position to inter connecting a larger variety of non-public computer, terminal and other peripheral devices with in a confined geographical arena, customarily less than 1KM across. LANs oftentimes operates with in a compact arena which include an place of business installing or a campus and is owned by the using affiliation. The popular Netware are Window Anti, Novell, and lantastic.
Network Trends
Communication is the methodology of relocating messages from one point to yet another. Following are the three simple components of a communication methodology:
This is a puzzling question to answer. A network can consist of 2 computers attached in mixture on a desk or it is going to consist of many Local Area Networks (LANs) attached in mixture to form a Wide Area Network (WAN) across a continent. The key is that two or extra computers are attached in mixture by a medium and are sharing materials. These materials almost naturally files, printers, complicated drives, or CPU variety-crunchingpersistent.
1. A sender (source), which creates the message to be transmitted.
Narrow band channel or the low speed channel is the slowest band, transmits the proof from 40 bit consistent with moment to 1200 bits consistent with seconds. Telegraph traces are the example of slim band channel.
Local Area Network (LAN)
Communication Channels
How ever, the messages that are transmitted are proof, no longer voice dialog. Thus, the electronics process that transfers proof from one point to other point is is known as proof communication process. Un like computers that methodology and rearrange proof, proof communication systems transmit proof from one point to yet another point with out any modification.
2. Voice Band Channel
LANs (local arena networks) are networks that connect computers and materials in mixture in a installing or buildings that are close in mixture.
What is a Network?
3. A receiver (sink), which receives the message.
