Study Notes
History of the Internet
- 1940s: The first electronic computers, like ENIAC, were built during World War II.
- 1950s: Computers like UNIVAC were developed for business and government use.
- 1962: J.C.R. Licklider proposed the concept of a global computer network in his "Intergalactic Computer Network" vision.
- 1964: Paul Baran and Donald Davies independently developed the concept of packet switching.
- 1969: ARPANET (Advanced Research Projects Agency Network) was launched, becoming the world's first packet-switched network.
- 1972: Email was introduced on ARPANET by Ray Tomlinson.
- 1973: TCP/IP protocol was developed by Vinton Cerf and Robert Kahn, allowing different computers and networks to communicate.
- 1977: ARPANET connected to other networks, forming the basis of what would become the internet.
- 1983: ARPANET adopted TCP/IP as its standard networking protocol.
- 1984: Domain Name System (DNS) simplified the way computers are addressed by using domain names (e.g., "example.com").
- 1989: Tim Berners-Lee proposed the idea of the World Wide Web, a system for linking hypertext documents accessed through the internet.
- 1991: The World Wide Web went live.
- 1993: The first web browser, Mosaic, was introduced.
- 1995: The commercial internet emerged.
- 2000s: High-speed internet access through broadband and Wi-Fi networks became widely available. Social media platforms like Facebook, Twitter, and YouTube transformed communication.
- 2010s: Cloud computing enhanced the power and accessibility of networked computing.
- 2020s: 5G networks began rolling out, and the Internet of Things (IoT) connected billions of devices.
Understanding How the Internet Works
- Private Network: Trusted networks like your home or office Wi-Fi. Devices can share files and discover each other.
- Public Network: Untrusted networks like those in coffee shops or airports. Devices disable discoverability and sharing for security.
- IP Addresses: Unique identifiers assigned to each device connected to the internet.
- IPv4: The original format (e.g., 192.168.0.1) with around 4.3 billion possible addresses.
- IPv6: A newer format (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334) with a vastly larger address space.
- DNS (Domain Name System): Translates human-readable domain names (like "example.com") into IP addresses that computers use to communicate.
- DNS Services: Provided by DNS servers that respond to queries from devices trying to resolve domain names into IP addresses.
Web Browser Navigation
- Back Button: Advances the page back by one.
- Forward Button: Advances the page forward by one.
- Reload Button: Reloads a page again.
- Home Page: The default page when the browser is opened.
Downloading and Uploading
- Downloading: Getting data from a server to your computer.
- Uploading: Sending data from your computer to a server.
- Connection Speed: Measured in bits per second (bps) (Kbps, Mbps, Gbps).
Streaming
- Streaming: Data is sent to a device in a continual and steady stream.
- Benefits of Streaming: Storage efficiency and accessibility across devices.
Search From the Address Bar
- Search: Clicking a suggested search term in the address bar will initiate a search using the selected search engine.
