Network Protocols

Flashcards covering key network protocols, their functions, and security aspects as a Cyber Transport Systems Apprentice.

Internet Control Message Protocol (ICMP)

A protocol primarily used for troubleshooting nodes on a computer network, utilizing echo reply requests (ping) to determine connectivity.

Telnet

A non-secure protocol that allows a computer network administrator to remotely configure network equipment or network devices.

Secure Shell (SSH)

A secure protocol that allows a computer network administrator to remotely configure a network device.

Simple Network Management Protocol (SNMP)

A protocol that provides mechanisms for collecting and organizing information from participating nodes on a computer network, and allows configuration changes and establishment of baselines.

Domain Name Server (DNS)

A protocol that translates domain names for websites to IP addresses, allowing users to type in website names instead of memorizing IP addresses.

Dynamic Host Configuration Protocol (DHCP)

A protocol that allows a node on a computer network to request an IPv4 address assignment from an external server.

Dynamic Host Configuration Protocol version 6 (DHCPv6)

A protocol that allows a node on a computer network to request an IPv6 address assignment from an external server.

Network Address Translation (NAT)

A protocol primarily used to associate a private IPv4 address on a computer network with a public IPv4 address for sending and receiving traffic over the public Internet.

Hypertext Transfer Protocol (HTTP)

A non-secure protocol that allows users of an Internet browser to request resources in the form of web pages and other content from an external web server.

Hypertext Transfer Protocol Secure (HTTPS)

A secure protocol that allows users of an Internet browser to request resources in the form of web pages and other content from an external web server.

Network Time Protocol (NTP)

A protocol designed to synchronize all participating pieces of network equipment and nodes on a computer network to within a few milliseconds of each other using the same Coordinated Universal Time (UTC).

File Transfer Protocol (FTP)

A protocol designed to transfer computer files between a client node and a server that is hosting the files on a computer network.
