Introduction to IP Networking

A set of vocabulary flashcards covering key concepts related to IP networking, TCP, UDP, and their roles in data communication.

IP

Internet Protocol; the primary communication protocol used for transmitting data across a network.

TCP

Transmission Control Protocol; a connection-oriented protocol that ensures reliable delivery of data.

UDP

User Datagram Protocol; a connectionless protocol that allows for faster transmission of data without guaranteed delivery.

Encapsulation

The process of wrapping data with the necessary protocol information before transmission.

Decapsulation

The process of extracting the encapsulated data from a packet upon receipt.

Ethernet

A family of networking technologies commonly used for local area networks (LANs).

IP Address

A unique identifier for a device on a network, used to send and receive data.

Port Number

A number assigned to a specific service or application, used to distinguish multiple services on a network.

Multiplexing

The ability to send multiple types of traffic simultaneously across a network.

Reliable Delivery

The assurance that data sent from one device to another has been received correctly.

Flow Control

A technique used to manage the rate of data transmission between devices.

Connection-oriented

A type of communication that requires a formal connection setup and teardown.

Connectionless

A type of communication that does not require a formal connection setup.

Non-ephemeral Ports

Permanent port numbers (0 - 1023) assigned to services and applications.

Ephemeral Ports

Temporary port numbers (1024 - 65535) used in establishing connections for a single session.

Well-known Ports

Ports that are universally recognized by specific applications, typically falling within the range of 0 - 1023.

DHCP

Dynamic Host Configuration Protocol; a network management protocol used to automatically assign IP addresses.

TFTP

Trivial File Transfer Protocol; a simple protocol for transferring files that doesn't require complex control mechanisms.

HTTP

Hypertext Transfer Protocol; the protocol used for transferring web pages on the internet.

HTTPS

Hypertext Transfer Protocol Secure; an extension of HTTP that uses encryption for secure communication.

SSH

Secure Shell; a protocol used for securely accessing network services over an unsecured network.

Ethernet Payload

The encapsulated data being transmitted across an Ethernet network, should include the header and trailer.

TCP Header

The data packet header that contains control information for TCP.

UDP Header

The data packet header that contains control information for UDP.
