2.1.1 TCP/IP Basics Flashcards
What does IP stand for?
Internet Protocol
What are the two types of IP, and what do they stand for?
- TCP - Transmission Control Protocol
- UDP - User Datagram Protocol
What is the difference between the client and the server?
Client - individual sending info
Server - receiver and processor of information
What is the Ethernet Payload, in essence?
all the steps that the information sent by a client to the server and vice versa passes through
What pieces of information come both before and after an Ethernet Payload?
Ethernet Header (before Payload, after Client), and Ethernet Trailer (after Payload, before Server)
What are the two components of the Ethernet Payload?
IP Header and IP Payload
What are the two components of the IP Payload?
TCP Header and a TCP payload (in that order)
What does the TCP payload contain?
Application data
What is the OSI Layer 4?
The transport layer which TCP operates at.
What is multiplexing?
the act of putting multiple applications inside different frames and send them across the internet at the same time
Which IP Protocol, TCP or UDP, is connection oriented?
TCP
Which IP Protocol, TCP or UDP, is considered “reliable?”
TCP
What does it mean for a connection to be “reliable?” How does this help with data transfer?
A reliable connection sends back an acknowledgement that the data was received.
This way, if any errors occur, the data is re-sent.
What does it mean for a protocol to be “connection oriented”?
A formal connection is established, same as saying hello, talking and then saying goodbye on the phone.
What are IPv4 sockets?
Physical sockets used to connect a client to a server and vice-versa.
