Study Notes
Basic Concepts in Computer Networking
- Building Blocks: Major components include nodes, links, and protocols that facilitate communication and data exchange.
- Network Nodes: Devices like routers, switches, and computers, which are connected to the network and communicate with each other. Non-network devices do not qualify as nodes.
Networking Protocols
- Function of Protocols: Establish rules and conventions for data transmission between network devices, ensuring that communication is effective and reliable.
- Examples of Protocols: Common protocols include TCP/IP, HTTP, and FTP, which enable different types of data transfers and communications.
Unique Identifiers
- IP Address: A unique numerical identifier assigned to every device on a network, allowing devices to send and receive information.
Network Architecture
- Client-Server Architecture: In this model, servers provide resources or services to client devices, managing their behavior and interactions within the network.
Security Measures
- Firewalls: Act as a security barrier that monitors and controls incoming and outgoing network traffic, protecting the internal network from unauthorized access and potential threats.
Network Topology
- Star Topology: A type of network structure where all devices are connected to a central hub, facilitating communication and simplifying troubleshooting.
Domain Name System (DNS)
- DNS Function: Translates human-readable domain names (like www.example.com) into IP addresses used by devices to locate each other on the network.
Geographic Scope of Networks
- Wide Area Network (WAN): A type of network that spans a large geographic area, such as a city, country, or even global connections, allowing connectivity across significant distances.
