Study Notes
Communication Networks
- Composed of interconnected devices capable of communication.
- Mobile Networks consist primarily of mobile devices.
- ATM Networks involve communication between ATMs.
Computer Networks
- A specific type of communication network allowing computers to exchange digital data.
- Utilize packet switching to transfer data efficiently.
- Components include a Source (initiator) and Destination (receiver).
- A Path is defined by the collection of communication links connecting Source to Destination.
- Links can be either wired (e.g., Ethernet, Fiber) or wireless (e.g., Wi-Fi, Bluetooth, Satellite).
Types of Computer Networks
Based on Architecture
-
Client/Server Network:
- One server provides resources to multiple clients.
- The server requires high-capacity hardware to handle various client requests.
- Offers centralized control, making security management easier.
- Risk of entire network disruption if the server fails.
-
Peer to Peer Network (P2P):
- Resources are distributed across multiple devices without a central control.
- Enhances resource availability; if one device fails, others remain operational.
- Reduced control can complicate security management.
- Commonly utilized in file-sharing systems (e.g., torrents, blockchain).
Based on Coverage Area and Size
-
Local Area Network (LAN):
- Connects a small number of personal computers within a limited geographic area (e.g., home, lab).
-
Wide Area Network (WAN):
- Covers expansive geographic areas, linking multiple smaller networks.
- The Internet serves as the prime example of a WAN.
Communication Protocols
-
Defined rules for facilitating information transmission between network devices.
-
Protocols vary based on data type being transferred.
-
HTTP / HTTPS:
- Hyper Text Transfer Protocol (HTTP) enables web page transfer from server to client.
- HTTPS adds SSL encryption for secure data transmission.
-
FTP / SFTP:
- FTP facilitates file transfers across networks.
- SFTP provides a secure method for transferring files between devices.
-
TCP / IP:
- Transmission Control Protocol (TCP) is crucial for reliable data transfer, working in tandem with Internet Protocol (IP).
