Study Notes
Computer Networks and Internet
- Computer networks connect computers and devices.
- Networks are categorized by their size.
- LAN (Local Area Network): Connects computers in a building or close proximity. Uses direct cables, radio, and infrared.
- WAN (Wide Area Network): Connects computers over larger distances, potentially thousands of miles. Utilizes long-distance transmission media.
- MAN (Metropolitan Area Network): Connects computers within a city or group of buildings. Commonly uses fiber-optic cable.
- CAN (Campus Area Network): A type of LAN connecting buildings on a campus.
- HAN (Home Area Network): A small network for devices in a home.
Networking Synergies
- Sharing hardware reduces costs and resources.
- Shared applications like software enable users to share resources and programs.
- Groupware facilitates communication and scheduling.
- Using network resources to share data is efficient.
Network Fundamentals
- Physical media: Cables (telephone lines, coaxial), microwaves, satellites, wireless, and fiber optic transmit network signals. They connect computers.
- Routers: Examine transmitted data and direct it to the proper destination.
- Switches: High-speed electronic devices that maintain connections between computers.
- Protocols: Standards dictating how network components communicate.
Network Architecture
- Network architecture is the overall design of a network.
- Layers separate functions and tasks.
- A protocol stack vertically arranges the layers, managed by own set of protocols.
Local Area Networks (LANs)
- LANs interconnect computers and peripherals within a building.
- LANs enable software, data, and peripherals access.
- LANs involve special hardware and software.
- Stations or nodes make up the computing components connected to a LAN.
- Peer-to-peer: All computers are equal with no dedicated file server.
- Client-server: Servers manage and store data; clients access data.
LAN Hardware and Software
- Hardware: Network interface cards (NICs) are computer expansion cards.
- Software: Operating system (like Unix, Linux, Windows, Mac OS) for network operations, with additional specialized software.
Peer-to-Peer Networks
- All computers are equal; no dedicated file server.
- Users decide which files and peripherals to share.
- Easy setup, but not suitable for large networks.
Client-Server Networks
- Employ various topologies (physical layouts).
- Networked computers (clients) and a network operating system (NOS).
- Clients request services (programs, data, or access to peripherals) from servers.
Network Media
- Twisted pair: Two insulated wires, commonly used in telephones.
- Coaxial cable: Insulated wire with braided outer wire, similar to cable TV.
- Fiber-optic cable: Glass fiber cables that send data as light impulses, capable of extended distances and high speeds.
- Infrared: Wireless technology using infrared signals to transmit data.
- Radio: Wireless data transmission using radio signals.
Types of Telephone Transmission Media
- Twisted pair copper wire: Used for telephone transmission.
- Fiber optics: Used for transmitting data as light impulses.
- Satellites: Used for transmitting data through satellites in space.
- Microwave: Used for sending data on microwave signals.
Internet History
- A timeline of key internet development including packet switching, ARPANET, TCP/IP, WWW, and commercial internet.
Local Area Network Diagram
- Diagram illustrating a simple LAN with PCs, a Router, server and printer.
Internet Diagram
- Diagram showing the flow of internet traffic from a home network through a router, to an internet service provider then the internet backbone ending at the domain services.
Web protocols-HTTP
- HTTP defines how webpages are transferred or transmitted.
- Web servers deliver web pages.
Web page tags and descriptions
- HTML tags describe the page structure and content, like headings, paragraphs, images, and hyperlinks. They control the format and appearance of the page.
HTML Document with example code
- Example HTML code demonstrating the basic structure of an HTML document.
Web Page Design
- Hypertext Markup Language (HTML) describes the structure of web pages and content displays.
Web Site
- A collection of related web pages.
- Index/Home page is the main page.
Web Page
- A single page of information, including links to other pages.
Home Page
- The main or first page of a website.
- Default starting page when the web browser launches or opens.
Link
- Words/images displayed to take the user to another web page.
Text Box
- A box where a single line of text can be entered.
Text Area
- A box used to input multiple lines of text.
Drop-down Box
- Displays list of options from which to choose (usually for selections).
Back
- Allows the user to revisit the previously viewed web page.
Most Popular Web Browsers (1995 - 2023)
- Graphical representation showing the popularity of different web browsers.
Search Engine
- A website that searches the internet for specific information.
Uniform Resource Locator (URL)
- Website or web resource address.
File Transfer Protocol (FTP)
- Transmitting files between computers, sometimes done anonymously.
- FTP Servers host these files and their collections.
