What is Router,Wifi And Broadband?

Broadband-

Broadband internet access is a high-speed connection to the internet that has generally 

superseded the use of dial-up connections. It is provided over your phone line (or 'landline') 

via satellite or cable. It gives constant internet access, usually for a monthly flat fee, 

although limits on downloads and other conditions can sometimes apply. 



Router-

A router is a device that directs data traffic along specific routes. A router sends information, such as email and the content of web pages, between your computer and the network server. It also connects networks and acts as a filter at a ‘gateway’ between them, channelling information to the correct IP address, unique to each computer. A router is also the device that keeps single computers, or entire networks, connected to the internet.

A router can be connected to your computer by wires (or cables). However, more commonly these days, routers are ‘wireless’, allowing several wireless-enabled devices to access the internet at any one time and enabling users to use the devices in various locations within range of the router.



Wifi-

Modems connect to the internet. Wifi, pronounced ‘why-fy’ enables you to connect to a modem without the use of wires. It uses low powered radio waves in the same way that your radio or television does. This means that you can use your laptop or other internet-enabled device anywhere in a building without having to install extra cables or phone lines, as long as the radio waves can reach the modem and it allows you to connect to it..

Wifi also allows several computers, laptops, printers and the like to be connected at any one time, essentially creating a network between all the devices in your home or office. Wifi is also increasingly found in public places, such as libraries and cafés, making it easy to access the internet while on the move, often for free.
