Study Notes
Networking Layers
- Application layer acts similarly to a manager in a company, ensuring requests (like web pages) are sent efficiently.
- Large data packets may need to be fragmented or chunked for transmission, akin to how a manager coordinates various shipping tasks.
- Layering in networking allows different functions to be managed separately, enhancing organization and efficiency in data transfer.
Protocols in Networking
- Protocols define the set of rules for communication between networks, ensuring layers on both client and server sides can correspond effectively.
- The transport layer is responsible for packet creation, numbering, and acknowledging receipt, facilitating reliable data exchange.
- Understanding between corresponding layers is crucial for tracking packet delivery and retransmission, minimizing data loss.
Concepts of Layering
- Layering involves defining interfaces for data exchange between layers, facilitating organized communication.
- Each layer communicates using defined syntax (packet framing and control signals) and semantics (interpretation of signals).
Observing Network Traffic
- Wireshark is a tool that captures and analyzes data packets flowing in a network, revealing communication patterns between applications and servers.
Working with Cisco Packet Tracer
- Cisco Packet Tracer allows users to create and modify web pages, demonstrating how devices communicate over the internet.
- Domain Name Service (DNS) translates user-friendly URLs to IP addresses, enabling proper routing to web servers.
IP Addressing and Subnet Masking
- A subnet mask determines the range of IP addresses within a specific network.
- For example, a subnet mask of 255.255.255.0 indicates 256 addresses available from 192.168.0.0 to 192.168.0.255, reserving the first (network address) and last (broadcast address) IPs for network identification and broadcast purposes.
- Devices within the same subnet follow the same starting three octets, allowing efficient routing and communication.
Dynamic Host Configuration Protocol (DHCP)
- DHCP allocates IP addresses to devices on a local network, facilitating efficient use of available network addresses.
- Routers, which serve as gateways between different networks, maintain separate address spaces for outward (internet-facing) and inward (local network) connections.
- Each interface on a router must belong to a distinct network, ensuring clear traffic segmentation and management.
