Study Notes
Address Resolution Protocol (ARP)
- ARP maps Internet Protocol (IP) addresses to physical machine (MAC) addresses in a local area network.
Secure Communication Protocol
- Secure communication over a network is commonly achieved using Secure Sockets Layer (SSL) or Transport Layer Security (TLS).
Router Purpose
- A router connects multiple networks and forwards data packets between them, determining the best path for data transmission.
OSI Model Logical Addressing
- The Network layer (Layer 3) of the OSI model is responsible for logical addressing through IP addresses.
Subnet Mask for Class C Network
- The subnet mask associated with the most host addresses in a Class C network is 255.255.255.0.
Email Protocol
- Simple Mail Transfer Protocol (SMTP) is primarily used for sending emails over a network.
Proxy Server Function
- A proxy server acts as an intermediary for requests from clients seeking resources from other servers, often used for anonymity and security.
Subnet Mask Purpose
- A subnet mask defines the network and host portions of an IP address, enhancing routing and contributing to efficient IP address management.
OSI Model and MAC Addresses
- The Data Link layer (Layer 2) of the OSI model is responsible for logical addressing using MAC addresses.
Internet Control Message Protocol (ICMP)
- ICMP is used for error messages and operational information exchange in an IP network, such as pinging a device.
Network Topology with Nodes in a Loop
- A ring topology is formed when each node is connected to exactly two other nodes, creating a closed loop.
Network Address Translation (NAT)
- NAT allows multiple devices on a local network to share a single public IP address, enhancing security and IP address management.
Firewall Purpose
- A firewall monitors and controls incoming and outgoing network traffic based on predetermined security rules.
Dynamic IP Address Assignment Protocol
- Dynamic Host Configuration Protocol (DHCP) is used for automatically assigning IP addresses to devices on a network.
Repeater Purpose
- A repeater regenerates and amplifies signals in a network, increasing transmission distance.
Secure File Transfer Protocol
- Secure Copy Protocol (SCP) or File Transfer Protocol Secure (FTPS) are commonly used for secure file transfer over a network.
Switch Function
- A switch connects devices within a single network and uses MAC addresses to forward data only to the intended recipient.
Star Network Topology Characteristic
- A star network topology features all nodes connected to a central hub or switch, offering easy troubleshooting and network management.
Domain Name System (DNS) Purpose
- DNS resolves human-readable domain names to IP addresses, enabling browser access to websites.
Secure Communication over Web Protocol
- Hypertext Transfer Protocol Secure (HTTPS) is the standard protocol for secure communication over a web browser.
Simple Network Management Protocol (SNMP) Purpose
- SNMP is used for monitoring, managing, and configuring network devices, allowing network administrators to oversee and maintain the network.
Linear Network Topology
- A bus topology is formed when devices are connected in a linear fashion along a single communication line.
Hub Purpose
- A hub connects multiple Ethernet devices, making them act as a single network segment, but does not filter traffic, leading to collision domains.
