Answer 1

Answer:

1) Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network to establish a connection to an Internet service provider by dialing a telephone number on a conventional telephone line.

2) Digital subscriber line is a family of technologies that are used to transmit digital data over telephone lines. In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line, the most commonly installed DSL technology, for Internet access. 

3) In telecommunications, cable Internet access, shortened to cable Internet, is a form of broadband Internet access which uses the same infrastructure as a cable television

Answer 2

Answer:

The following Internet connectivity is as follows-

• Dial-up: Dial-up internet connectivity is an old technology that uses a modem and telephone line to establish a connection between a computer and an internet service provider (ISP). This method of connectivity is relatively slow, limited to 56 Kbps, and is not commonly used anymore.

• DSL (Digital Subscriber Line) is a broadband internet connection that uses telephone lines to transmit data. It provides a faster and more reliable connection than dial-up by using a higher frequency range on the telephone line. DSL requires a special modem that converts digital data into signals that can be transmitted over the telephone line.

• Cable internet access is a high-speed internet connection that uses the same coaxial cable as cable TV. It provides faster speeds than DSL and is a popular option for home internet users. Cable internet requires a cable modem, which connects to the cable outlet in your home and provides a high-speed internet connection.

• 3G (Third Generation) is a mobile telecommunications technology that allows for high-speed wireless data transfer. It is commonly used in mobile phones and provides internet connectivity on the go. 3G networks use different frequencies than voice calls and allow for faster data transfer rates than earlier mobile technologies.

• WiMAX (Worldwide Interoperability for Microwave Access) is a wireless broadband technology that provides high-speed internet access over a wide area. It can provide internet connectivity to areas that are difficult to reach with traditional wired connections. WiMAX uses radio waves to transmit data and requires a WiMAX modem to connect to the internet.

• Wi-Fi (Wireless Fidelity) is a wireless networking technology that allows devices to connect to the internet without using cables. It is commonly used in homes and businesses to provide internet connectivity to multiple devices. Wi-Fi requires a wireless access point or router, which creates a wireless network that devices can connect to.
