Defination:
Internet infrastructure refers to the physical components, transmission mediums, and software that facilitate the connection of computers and users on the Internet. It plays a crucial role in hosting, storing, processing, and delivering the information that makes up websites, applications, and digital content. Here are simplified explanations of different types of internet infrastructures:
Different internet infrastructure :
Dial-up Internet Access:
- What it is: Users connect to the Internet using a modem connected to their computer, which dials a phone number provided by their Internet Service Provider (ISP).
- How it works: Data is sent over an analog, public-switched telephone network, and the modem converts analog data to digital and vice versa.
- Key point: It’s like making a phone call to connect to the Internet.
Integrated Services Digital Network (ISDN):
- What it is: An international standard for sending voice, video, and data over digital telephone lines or regular telephone wires.
- Key point: It’s a digital communication method using existing telephone infrastructure.
Broadband ISDN (B-ISDN):
- What it is: Similar to ISDN, but it transfers data over fiber optic telephone lines instead of regular telephone wires.
- Key point: Uses advanced technology like SONET for faster data transfer, but not widely implemented.
Digital Subscriber Line (DSL):
- What it is: Often called “always on” because it uses existing 2-wire copper telephone lines connected to a premise, delivering service simultaneously with wired telephone service.
- Key point: It’s a high-speed connection method using traditional telephone lines.
