Study Notes
File Sharing and Networking Protocols
- BitTorrent: A decentralized file-sharing protocol that spreads file server roles across multiple computers.
- Access Permissions: Setting a file in a home network to 'Read' allows others to view it without making changes.
- Internet Protocols: The foundational protocols developed from ARPANET facilitate seamless data travel across international borders.
- Network Topology: A star topology connects multiple devices to a central hub, enhancing organization and connectivity.
Internet Connection Quality
- Packet Loss: Zero packet loss indicates a smooth experience during activities like gaming.
- DNS Server Issues: If the primary DNS server fails, Google's public DNS can be utilized as a backup.
- Cable Internet Speed: Fluctuating speeds below the promised rate may indicate bandwidth contention with other users.
Home Networking Setup
- Home Router Configuration: The first step is to set a strong password for router configuration.
- Guest Network: Configuring a guest network ensures visitors cannot access shared files on personal devices.
- Static IP Address: Required for running services like a Web or FTP server from home.
Data Transmission and Security
- Bandwidth Measurement: Digital data channel bandwidth is measured in bits per second.
- Encryption Protocols: WEP is an outdated and insecure encryption method; modern standards are recommended.
- Dynamic IP Addresses: Free WiFi often assigns dynamic IP addresses, leading to changes each connection.
IoT and Connectivity
- IoT Technologies: Bluetooth LE, ZigBee, and Z-Wave are low-power, short-range wireless technologies designed for Internet of Things networks.
- Hotspot Security Indication: A hotspot that requires no password is likely unencrypted.
- Ethernet Jack Appearance: Resembles a larger version of a standard telephone jack, used for wired connections.
Diagnostic Tools and Trouble Shooting
- Tracert/Traceroute: This tool identifies connections along a network path and may show "Request timed out" if routers employ security measures.
- Signal Integrity: Error correction processes help clean and restore corrupted signals in network protocols.
Mobile and Alternative Internet Access
- DSL Connections: The wiring for DSL internet is similar to standard telephone lines, illustrating its legacy technology.
- Tethering: A feature that allows mobile phones to share their internet connection with devices like laptops.
