Study Notes
Network Basics
- Transmission Media: Also referred to as communications channel, it facilitates data transfer between devices.
- Node: Every computer or device connected in a network is designated as a node.
- Personal Area Network (PAN): A PAN connects devices within a small workspace.
- Voice over Internet Protocol (VoIP): Services like Skype and FaceTime facilitate voice and video calls via the Internet.
Local Area Network (LAN)
- Token Ring: A likely network standard for local area networks.
- Ethernet: The most prevalent standard for LANs, facilitating data transfer between devices.
- Wi-Fi Standards: Identified by the 802.11 series, representing wireless local area network standards.
- Network Adapter (NIC): Used to enable devices lacking built-in networking capabilities.
Wireless Technologies
- Microwave Transmission: Also known as fixed wireless.
- Radio Frequency Identification (RFID) Reader: Functions as a transceiver for identifying objects wirelessly.
- Bluetooth: Allows communication between devices without requiring direct line-of-sight.
Network Models
- Client/Server Model: In this architecture, clients request data, and servers supply it.
- Peer-to-Peer (P2P): All connected computers have equal status and share resources without central management.
Internet Connection and Protocols
- Bandwidth: Measures the amount of data that can be transferred over a network in a given time.
- Protocols: Established rules for communication across networks.
- Transmission Control Protocol/Internet Protocol (TCP/IP): The foundational protocol of the Internet.
Types of Networks
- Wide Area Network (WAN): Covers expansive geographical areas.
- Local Area Network (LAN): Confined to a limited physical space, such as a building.
- Metropolitan Area Network (MAN): Serves larger areas than LANs, like a city.
- Extranet: A secure extension of an organization's intranet that allows outside access.
Network Hardware
- Router: Connects multiple networks and routes data between them.
- Modem: Converts analog signals to digital and vice versa for data transmission across phone lines.
- Network Interface Card (NIC): Essential for connecting a computer to a network.
Internet Access
- Fractional T1 Lines: Shared connections used by home and small business users.
- Fixed Wireless Access: Provides broadband connectivity using microwave transmission.
Network Connectivity
- Ethernet Cable: Offers faster connection speeds compared to Wi-Fi.
- USB Connections: Typically used to connect peripherals, including modems to PCs.
Data Management
- Packet Switching: Splits large Internet messages into smaller packets for efficient transmission.
- Intranet: A private network allowing secure information access for employees.
General Knowledge
- Net Neutrality: Rules that prevent ISP discrimination against specific services.
- Location Determination: IP addresses can provide rough geographical information even if assigned randomly.
Testing and Troubleshooting
- Network Signals: Red X on network icons usually indicates an Ethernet cable disconnection.
- Speed Variability: Actual network speed may differ from advertised rates.
Miscellaneous
- Personal Area Network (PAN): Commonly utilizes Bluetooth technology for wireless communication.
- Remote Access: VPNs offer secure tunneling over public internet paths for private communications.
