★ Solution :-
• Wired Internet Connections : These are the connections of internet, where there is the requirement of a wire source from the service provider to the surrounding or locality of the user. Actually when someone used wired connection, service provider provides the internet connection through a wire source from the service provider's office to the user's home.
• Wireless Connection : These are the connections which don't require any wired system for getting internet. The service provider sets up an internet or signal tower which works by reflection from satellite by broadcasting and thus provide internet to all the users using that connection.
• Wired Internet connectivity :-
1.) Dial - UP :- This is a type of wired internet connection. In this the service provider provides internet connection by the use of a telephone line which get's activated by the simple códe also called as telephone number. This establishes a connection between the service provider and the user which gives Internét.
2.) DSL :- This is actually a type of Dial - Up connection only. Actually long distance wired connection reduces the speed of internet. So the service provider provides a phone type device which is attached to the wall of the house of the user and this phone is attached to the wires of dial up connection. This provides a fast Internet because the bandwidth speed increases.
3.) Cable Internet Access :: This is a type of internet connection based on subscriber line which is provided to the user from long distances by the service provider. The wires are in forms of cables either underground or at common places which provides a platform to give internet services. The best example for such type of connection is Broad Band.
• Wireless Internet Connectivity :-
1.) 3G :: This is the 3rd Generation wireless internet connection provided by the service provider to the users. This is fast internet connection which doesn't requires any wires. It receives signals from the transmitter at the internet towers of the service provider. The range of such connections is 1 Kbps - 500 Kbps. This is offered by several companies like Airtel, Vodaphone, etc.
2.) Wi - Fi :: Wi - Fi stands for wireless fidelity which is a function provided in new generation digital gadgets like laptops, computer, phones, etc. which makes the gadgets interface with the internet present in their surrounding. Actually the internet connection cloud is created by an internet providing device using portable hotspots. Then the gadgets using wi - fi can enter the internet cloud to use the internet which is permitted by the internet provide device.
3.) WI - MAX :: WIMAX actually doesn't rrally provides internet. It stands for Worldwide Interoperability for Microwave Access which helps in providing the services to users like portable hotspots, mobile data, etc. to make use of the feature of wifi. They can easily connect the devices of the world using clouds and thus make different devices use the wifi.
Answer:
wired - Wired communication refers to the transmission of data over a wire-based communication technology. Wired communication is also known as wireline communication. Examples include telephone networks, cable television or internet access, and fiber-optic communication.
Wireless - Wireless technology provides the ability to communicate between two or more entities over distances without the use of wires or cables of any sort. This includes communications using radio frequency (RF) as well as infrared (IR) waves .
3G - The number three in the name of 3G does a pretty good job of answering this question. Basically, it's the third generation of access technology that allows connecting mobile phones to the internet (wherever they may be). Each new generation has new frequency bands and higher data transmission rates.
DSL - DSL (Digital Subscriber Line) is a modem technology that uses existing telephone lines to transport high-bandwidth data, such as multimedia and video, to service subscribers. DSL provides dedicated, point-to-point, public network access.
Wimax - WiMAX is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide multiple physical layer and Media Access Control options.
Cable Internet - Cable television companies provide broadband using the same coaxial cables that deliver pictures and sound to your TV set. A cable modem is an external device that normally has two connections: one to the cable wall outlet, the other to a computer. Cable Internet is usually faster than DSL.
Dial up - Dial-up refers to an Internet connection that is established using a modem. The modem connects the computer to standard phone lines, which serve as the data transfer medium. After the dial-up connection has been established, it is active until the user disconnects from the ISP. ...
Wifi - WiFi is a universal wireless networking technology that utilizes radio frequencies to transfer data. WiFi allows high-speed Internet connections without the use of cables. The term WiFi is a contraction of "wireless fidelity" and commonly used to refer to wireless networking technology.
