Study Notes
The Internet and World Wide Web
- The World Wide Web (WWW) was developed in 1989 by Tim Berners-Lee and colleagues at CERN.
- The World Wide Web is a global information retrieval service that uses the HyperText Transfer Protocol (HTTP) to standardize communication between servers and clients.
Development of the Internet and Web
- In 1992, a group of students and researchers at the University of Illinois developed the Mosaic browser, which allowed users to see words and pictures on the same page and navigate using scrollbars and clickable links.
- In 1994, Jerry Yang and David Filo founded Yahoo!, a global Internet services provider that provided users with online utilities, information, and access to other Web sites.
- WWWW (World Wide Web Worm) is one of the earliest search engines for the World Wide Web.
The Internet and Its Components
- The Internet is a global wide area network (WAN) that connects billions of computers and other electronic devices via servers and routers.
- The Internet was first described as a global network of linked computers in 1974.
- The Internet is often used interchangeably with the World Wide Web, but they are not the same: the Internet refers to the global communication system and infrastructure, while the World Wide Web is one of the services that runs over the Internet.
History of Communication
- In 1844, Samuel Finley Breese Morse developed the Morse Code, which assigns a letter on the English alphabet using a set of dots and dashes to allow simple transmission of complex messages across telegraph lines.
Types of Networks
- Wide Area Network (WAN): a network that connects devices over a large geographical area.
- Wireless Local Area Network (WLAN): a wireless distribution method for two or more devices that use high-frequency radio waves and often include an access point to the Internet.
- Virtual Private Network (VPN): a secure connection to another network over the Internet that encrypts internet traffic and routes it through a VPN provider's server.
- Home Area Network: a network built using two or more interconnected computers to form a local area network (LAN) within the home.
Network Topology
- Bus Topology: each node is linked to one other node only, and data transmission occurs in one direction.
- Ring Topology: each node is linked to two other nodes, forming a ring, and data can flow bidirectionally.
- Star Topology: a central server node is linked to multiple client network devices, and data doesn't have to go through each node.
Human-Computer Interaction
- Human-computer interaction (HCI) is a multidisciplinary field of study focusing on the design of computer technology and the interaction between humans and computers.
- The goal of HCI is to optimize how users and computers interact by designing interactive computer interfaces that satisfy users' needs.
