Study Notes
Coaxial Cables
- Used for cable television and broadband internet connections.
- Composed of copper or aluminum conductors encased in insulating layers.
- Metal shields are incorporated for protection.
Fiber Optic Cables
- Transmit data using pulses of light through thin glass or plastic strands.
- Offer high-speed data transfer with minimal signal loss.
- Ideal for fast internet and long-distance communication.
Ethernet Cables
- Often referred to as Cat5e, Cat6, or Cat7.
- Utilize twisted pairs of copper wires for local area network (LAN) connections.
- Provide a reliable and familiar solution for wired internet and local network setups.
The Internet
- A global system of interconnected computer networks that allows billions of users to communicate and access information worldwide.
- Uses the standardized Internet Protocol Suite (TCP/IP).
- Also known as a network of networks.
Connecting to the Internet
- Requires an Internet service provider (ISP) and a modem or Internet-ready cable digital subscriber line (DSL).
- Modem connects the home network to the ISP.
- Router manages traffic within the local network, directing data between devices and enabling communication.
Connecting to the Internet (Cables)
- Coaxial cables: commonly used for cable television and broadband internet connections.
- Fiber optic cables: transmit data using light pulses, offering high-speed data transfer and minimal signal loss. Ideal for fast internet and long-distance communication.
- Ethernet cables: used for local area network connections, providing a reliable solution for wired internet and local networks.
Connecting to the Internet (Devices)
- Switch: connects various devices within a local network, allowing efficient communication.
- Access point: enables wireless devices to connect to a wired network via Wi-Fi.
- Server: a digital hub that hosts websites, stores files, and manages various tasks, ensuring secure and efficient data access.
How the Internet Works
- Uses Transmission Control Protocol (TCP) to send and receive data.
- TCP breaks large data chunks into smaller packets.
- Internet Protocol (IP) is responsible for sending these packets across the internet.
- Microwave signals are used for wireless transmission.
- Modems and routers convert these signals into binary signals (1's and 0's).
- TCP detects lost or error packets due to network congestion or traffic load balancing.
- TCP requests packets to be resent from the source.
- Packets are reassembled at the receiving end to reconstruct the original data.
IP Address
- Every computer connected to the internet has a unique IP address.
- Consists of 4 numbers (octets) separated by dots.
- Each number ranges from 0 to 255.
- Changes whenever you connect to different networks.
URL (Uniform Resource Locator)
- Also known as the website address.
- Every webpage has a unique URL.
- Represents the address of a web document on a computer.
- Established by Tim Berners-Lee in 1990.
- Different extensions, like .com, .org, .net, .gov, and .edu, indicate the purpose of the website.
Audio and Video
- Video uses motion and sound to create the illusion of movement.
- A sequence of still images or frames played in succession.
- Each frame contains a snapshot of the scene.
