LESSON 1 Flashcards
is a worldwide computer network that transmits a variety of data and media across interconnected devices. It works by using a packet routing network that follows Internet Protocol (IP) and Transport Control Protocol (TCP).
INTERNET
THE ADDRESS SYSTEM
refers to a set of rules that govern how data packets are transmitted over a network
INTERNET PROTOCOL (IP)
THE RELIABLE MAIL CARRIER is like a reliable mail carrier who ensures your letters arrive safely and in order
TCP (TRANSMISSION CONTROL PROTOCOL)
TCP Here’s how it works:
*Breaking into Pieces
* Labeling
*Delivery Confirmation
*Error Checking
If you’re sending a big package (like a book), the mail carrier breaks it into smaller packages (data packets).
Breaking into Pieces
Each package is labeled with its destination and a sequence number, so the recipient knows how to put the pieces back together.
Labeling
The mail carrier waits for a confirmation (acknowledgment) from the recipient that the packages have arrived. If no confirmation is received, the mail carrier will resend the missing packages.
Delivery Confirmation
if a package arrives damaged, the recipient can request a replacement for that specific package.
Error Checking
