Introduction to IP and Networking Concepts 2.1

A set of vocabulary flashcards covering essential terms and concepts related to networking and Internet Protocol (IP).

IP (Internet Protocol)

A protocol used to send data across networks, likened to a truck transporting information.

TCP (Transmission Control Protocol)

A connection-oriented protocol ensuring reliable delivery of data between devices with acknowledgments.

UDP (User Datagram Protocol)

A connectionless protocol that sends data without guarantees of delivery or retransmission.

Flow Control

A mechanism that manages the rate of data transmission between a sender and a receiver.

Encapsulation

The process of wrapping data with protocol information at each layer in a network communication.

Decapsulation

The process of unpacking the data from its packets as it moves up the protocol stack.

Ephemeral Ports

Temporary ports assigned for short-lived communication sessions between network devices.

Nonephemeral Ports

Permanent port numbers used for specific services, typically ranging from 0 to 1023.

Multiplexing

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

TCP vs UDP

TCP is reliable and connection-oriented; UDP is faster, with low overhead, but unreliable.

Port Number

A number assigned to a specific service on a device, used to route data correctly.

Well-Known Ports

Ports ranging from 0 to 1023 that are universally recognized for specific services.

HTTP (Hypertext Transfer Protocol)

A protocol used for transmitting web pages over the internet, typically using TCP port 80.

VoIP (Voice over IP)

A method of delivering voice communications over the internet, often using UDP.

DHCP (Dynamic Host Configuration Protocol)

A protocol used to automatically assign IP addresses to devices on a network.

TFTP (Trivial File Transfer Protocol)

A simple protocol to transfer files without the need for complex overhead, using UDP.
