Study Notes
Types of Networks
- LAN (Local Area Network) connects a group of devices, such as desktop PCs and printers, in an office or building using cables.
- MAN (Metropolitan Area Network) serves a larger area, like a city, and connects multiple LANs together.
- WAN (Wide Area Network) spans a larger geographic area, connecting LANs across the country, using devices like telephone lines, satellite dishes, or radio waves.
Network Connection
- Access device: a personal computer with a NIC (Network Interface Card).
- Physical connection: connecting to a wired (cable) or wireless LAN.
- For MAN and WAN, an ISP (Internet Service Provider) is required.
Internet Connection
- ISP: a company that connects users to its servers, allowing access to the Internet.
- ISP servers connect users to MAN, WAN, or other WANs.
- WAN also connects users to the Internet if the ISP allows access to other WANs.
Internet Overview
- The Internet is a global system of interconnected computer networks.
- It uses WAN to communicate between networks and devices.
- Bandwidth: the data transmission rate, measured by the amount of data sent through a channel in a given time.
- Broadband: a very high-speed bandwidth connection.
Network Capabilities
- Enhanced capabilities when devices are connected to form a network.
- Basic services offered by computer networks include:
- File sharing
- Instant messaging
- Online gaming
- Printing
- File server
- World Wide Web
