What are the differences between baseband and broadband transmission systems? How do repeaters and bridges work?

Difference Between Base Band and Broad Band Transmission Systems:

Base Band:

(1) In a baseband transmission system, the data sent from the computer is sent unaltered over the network connection.

(2) Modulation is not required in baseband transmission systems.

(3) In a baseband transmission system, multiple signals cannot be transmitted over a single pair of wires simultaneously.

(4) Low cost in baseband transmission system.

(5) Benefits are less available in baseband transmission systems.


Broadband:

(i) In broadband transmission system, the information received from the computer is modulated by high frequency and sent over the network connection.

(ii) Amplitude modulation and demodulation are required in broadband transmission systems.

(iii) In broadband transmission system it is possible to establish multiple connections simultaneously through one connection path

(iv) Cost of broadband transmission system is high.

(v) More benefits are available in broadband transmission systems.


Repeater, Bridge, Router and Gateway


Repeater: Repeater is a device which is used to amplify the signal. Before crossing the distance of 185 meters, if the signal is amplified using a repeater, it can travel another 185 meters. It works at the physical layer of the OSI model.

Bridge: When there is a need to connect two roads or a means of transportation over a river is needed, then we use a bridge. In computer terms, a bridge is a mechanism that connects two or more "local area networks" or LANs. That is, a bridge is a device that connects multiple network segments. It is a bridging table to keep track of the different devices on each segment. It works at the datalink layer of the OSI model.

Bridges are very similar to routers, but the difference is that routers can inspect data passing through it, or put up firewalls as needed. But Bridge does none of these things. It simply aggregates multiple LAN connections. However, it is possible to exchange data between multiple protocols through bridges.

What is transmission media? Introduction to different types of data transmission cables

Transmission media: When a PC communicates or wants to communicate with another PC, it has to take the help of some transmission media. The most commonly used media in the network are twisted pair cable, coaxial cable, fiber optic cable. Nowadays, the use of optical fiber is increasing greatly. Radio wave, microwave and infrared technologies are prominent among wireless media. Among these mediums, optical fiber has the highest data transfer speed. The type of medium used in a network depends on the type and location of that network. The connection system for exchanging information between the sender and the remote receiving end is called a channel. The means or methods used to implement the channel are called media. such as-- (i) Cable or wire. (ii) Common telephone lines. (ii) Radio waves. (iv) Microwave. (v) Geo-satellite systems etc. Cable or Wire: Cable is an important medium in data communication. Cables are generally used for data transfer over short range networking such as LAN...

What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant ?

Today we talk about What are the things to consider when buying a WiFi or broadband router for home, office, park and restaurant .I never like huge introduction about any topic . I always like very shortly introduce any-things to my viewers without any-type boring .So let's began the leanrning :- 1. Decide in advance how many devices you will use. 2. Decide how much space you need coverage. 3. Understand the structure of your home. WiFi signals become weak to penetrate the walls. That is why good coverage is not available. If you have a lot of walls in your house and you want to get coverage in the whole house, then you need a router with high power and wall penetration feature. 4. Decide what features you need in addition to the internet connection. Such as: - 4.1 3G 4G Modem Support- There are many routers that can use the modem. Those routers have a USB port and a one port so that broadband lines can be used. But remember that the modem must have the ability to auto-connect. Not...
