Study Notes

Network Types

PAN (Personal Area Network): Connects personal devices like smartphones and laptops within close range using wired (USB, Lightning) or wireless (Bluetooth, Wi-Fi) connections.
LAN (Local Area Network): Covers small areas (homes, offices); utilizes wired (Ethernet) or wireless (Wi-Fi) tech, enabling resource sharing among workstations and devices.
WMN (Wireless Mesh Network): Consists of numerous wireless devices directly communicating, enhancing connection range; commonly used in IoT applications (e.g., smart home devices).
MAN (Metropolitan Area Network): Spans multiple buildings or city portions; often arises from cooperative efforts, using both wired and wireless technologies.
WAN (Wide Area Network): Encompasses vast geographic areas comprising multiple smaller networks; the most recognized example is the Internet.

Internet Connectivity

Internet Service Provider (ISP): Essential for Internet access, providing connections like DSL and cable; upload speeds typically slower than download speeds.
Bandwidth: Represents the theoretical data transmission capacity over a network; distinct from actual data throughput, which is the average speed achieved.
Cable Internet: A broadband solution utilizing existing cable TV infrastructure, maintaining simultaneous TV and Internet connections through a coaxial cable.
DSL (Digital Subscriber Line): Delivers broadband over copper phone lines, enabling voice and DSL usage concurrently without disruption.
Dedicated Line Using Fiber Optic: Provides a private, shared broadband connection from an ISP to home or business, supporting various services over fiber-optic cable.
Satellite Internet: Uses satellite dishes for high-speed connections in remote areas; suffers from latency and requires line-of-sight for optimal performance.
Wireless Wide Area Network (WWAN): Based on cellular towers for broadband communication accessible via mobile devices, offered by carriers like Verizon.

Network Addresses and Protocols

IP Address: A unique identifier for each device on a network, formatted either as a 32-bit (IPv4) or 128-bit (IPv6) string.
TCP/IP: A suite of protocols governing network communication and IP addressing.
Host: Any device that requests or provides services on a network; requires TCP/IP details to communicate.
DNS (Domain Name System): Translates website names into IP addresses, utilizing a database for name resolution.
DHCP client: A device requesting IP address information from a DHCP server; enables dynamic address assignment.

Network Hardware and Features

Network Interface Card (NIC): Enables network communication for devices.
Router: Manages traffic between networks, determining the best routes for data transfer.
Default Gateway: Acts as a routing point for data going to external networks or the Internet.
MAC Address: A device's unique identifier used for local network identification; usually displayed on the device.
Wake on LAN: Allows network adapters to wake devices remotely upon receiving specific network signals.

Security and Management

Quality of Service (QoS): Prioritizes specific traffic types on a network, ensuring optimal performance for important applications.
Address Reservation: A method where the DHCP server assigns consistent IP addresses to devices, providing predictability and management ease.
MAC Address Filtering: Limits network access to specified devices but is easily circumvented, making it a weak security method.
Port Forwarding: Enables specific traffic from the Internet to access designated computers/ports within a local network.
WPA (Wi-Fi Protected Access): A more secure encryption method for wireless networks, utilizing dynamic keys; however, TKIP is outdated and no longer deemed secure.

Additional Concepts

Full Duplex: Allows simultaneous two-way data transmission between devices.
Half Duplex: Permits one-directional transmission at any given moment.
Universal Plug and Play (UPnP): Facilitates automatic discovery and communication between devices on a local network, though it poses security risks due to reduced barriers.
