Study Notes
Internet Essentials
- Connection to the web requires two essentials: internet access and a web browser.
Internet Overview
- Defined as a global system of interconnected networks utilizing standardized network protocols.
- Consists of a vast network of networks allowing interconnectivity for computers and digital devices.
- Intentionally designed to be decentralized, distributing control and authority across many independent entities.
Interconnected Networks
- Acts as a platform for sharing diverse, current information from various sources globally.
Network Protocols
- Communication and data exchange relies on Transmission Control Protocol (TCP) and Internet Protocol (IP).
Major Components of the Internet
Web Server
- Functions as software using Hypertext Transfer Protocol (HTTP) to respond to client requests.
- Moreover, functions as hardware housing web server software and website-related files, requiring internet connectivity.
Web Browser
- Software application crucial for retrieving content from web servers and displaying it to users.
Types of Internet Service
- Dial-up: Uses a modem to establish a connection between a computer and an ISP server.
- Broadband: High-speed internet that surpasses traditional dial-up, transmitted via cable or telephone lines.
- DSL (Digital Subscriber Line): Provides broadband via existing telephone lines.
- Cable: Offers high-speed internet through cable modems.
- Satellite: Internet access via satellites in Earth’s orbit.
- ISDN (Integrated Service Digital Network): Transmits voice and data over digital lines in a circuit-switched telephone network.
- Cellular: Wireless internet through cell phones with varying speeds from 3G to 5G.
Factors for Choosing an ISP
