Study Notes
Network Overview
- A network is a group of interconnected devices, people, or systems that share and communicate information.
Network Types
-
PAN (Personal Area Network): A small network designed to connect devices that are close to a single user.
- Examples: smartwatch and smartphone, laptop and phone
- Uses: file sharing between devices, internet sharing using mobile hotspot
-
LAN (Local Area Network): A network in a small area like a home, school, or office.
- Examples: computers in a school lab that share a printer, devices (laptop, phone, smart TV) connected to a home Wi-Fi
- Uses: file sharing, printing documents from multiple computers to the same printer
-
WAN (Wide Area Network): A network that connects computers over large areas like cities or countries.
- Examples: the internet, banks linking branches across the country
- Uses: watching videos on YouTube, sending emails, making video calls with friends in different places
Internet
- The Internet is a massive network that connects computers and devices worldwide.
IP Address
- An IP address is a unique numerical label assigned to a device on a network (internet or local) used for communication.
- Example: 192.168.1.1
- Procedure: find your device's IP address.
WWW (World Wide Web)
- WWW stands for World Wide Web.
- A collection of resources and users on the internet.
- A way that computers can exchange information.
Internet Domain
- An internet domain is a text-based address like example.com that helps access a website easily.
- Domains make remembering websites easier than remembering complex IP addresses.
- Example of a domain: .com, .net, .edu
Network Connections
-
Wired Connection: Uses physical cables to connect devices to the internet.
- Examples: Ethernet cables, fiber optic cables
-
Wireless Connection: Uses radio waves to connect devices to the internet without cables.
- Examples: Wi-Fi, Bluetooth
Advantages of Wireless Connections
- Mobility: Connect from anywhere within range.
- Convenience: Easy to set up and use with multiple devices.
- No Cables: Reduces clutter and makes device movement easy.
Disadvantages of Wireless Connections
- Speed: Generally slower than wired connections.
- Interference: Can be affected by walls, other devices, and distance.
- Security Risks: More vulnerable to unauthorized access.
Advantages of Wired Connections
- Stability and Reliability
- Faster Speeds
- Security
- Low Latency
- No Signal Interference
- Power Efficiency
Disadvantages of Wired Connections
- Limited Mobility: Devices must be physically connected.
- Installation: Can be complicated to set up in large spaces.
- Clutter: Cables can create a messy environment.
