Study Notes
OSI Model and Protocols
- The Network Layer (Layer 3) is responsible for logical addressing in the OSI model.
Email and Communication
- The primary purpose of SMTP (Simple Mail Transfer Protocol) is to facilitate email communication in a network.
Network Devices
- A router's primary function is to connect multiple networks together and route traffic between them.
IP Addresses and Subnets
- In a Class C network, the subnet mask 255.255.255.0 is associated with the most host addresses.
Address Resolution
- ARP (Address Resolution Protocol) resolves IP addresses to MAC addresses in a network.
Network Security
- SSL/TLS (Secure Sockets Layer/Transport Layer Security) is used for secure communication over a computer network.
Firewalls
- The primary purpose of a firewall is to block unauthorized access to or from a network while allowing authorized communication.
File Transfer
- SFTP (Secure File Transfer Protocol) is commonly used for secure file transfer over a network.
Network Topology
- A ring topology is formed when each node is connected to exactly two other nodes, forming a loop.
Network Devices
- A bridge operates at the Data Link Layer (Layer 2) of the OSI model.
Network Address Translation
- The primary purpose of NAT (Network Address Translation) is to allow multiple devices to share a single public IP address.
IP Address Management
- DHCP (Dynamic Host Configuration Protocol) is used for dynamically assigning IP addresses in a network.
Error Reporting
- ICMP (Internet Control Message Protocol) is used for error-reporting and diagnostics in a network.
Network Devices
- A repeater's primary function is to amplify weak signals and extend the distance over which data can be transmitted in a network.
Secure Communication
- HTTPS (Hypertext Transfer Protocol Secure) is used for secure communication over a web browser.
Network Gateway
- A gateway is a node on a network that serves as an entrance point to another network.
