Study Notes
Networking Basics
- A network consists of two or more computer systems linked by a transmission medium that share protocols for data exchange.
- Nodes represent devices that send, receive, and forward data; links are the communication pathways connecting them.
- Types of nodes include:
- Intermediate Nodes: Responsible for forwarding data.
- End Systems (Hosts): Devices that send and receive data traffic.
Client-Server vs. Peer-to-Peer Networks
-
Client-Server Network:
- Servers provide applications and resources to other hosts.
- Clients consume services offered by servers.
- Common in business and enterprise environments.
- Hosts typically act as clients, but can also function as servers (e.g., a web server providing services to a browser client).
-
Peer-to-Peer Network:
- Each host functions as both a client and a server, allowing decentralized management and distribution of services.
- Suitable for smaller networks, also known as workgroups.
- More prevalent in residential settings.
Network Appliances, Applications, and Functions
-
Appliances:
- Specialized platforms designed for specific networking roles, such as:
- Switches and Routers: Forward data.
- Firewalls and Intrusion Detection Systems: Enforce security rules.
- Load Balancers and Proxies: Enhance network performance.
- Can be deployed as physical hardware or virtual appliances running on hypervisors.
- Specialized platforms designed for specific networking roles, such as:
-
Applications:
- Nodes and links enable shared applications that provide useful services like file sharing and email communication.
-
Functions:
- Networks can include properties for different functionalities:
- Virtual Private Networks (VPNs): Allow secure connections to local networks over the Internet.
- Quality of Service (QoS): Optimizes network performance for time-sensitive applications like voice or video.
- Networks can include properties for different functionalities:
