Term
| Transmission Control Protocol/Internet Protocol (TCP/IP) |
|
Definition
-It's a set of rules that allows different devices to communicate over the internet.
TCP (Transmission Control Protocol) ensures reliable communication by establishing a connection between devices, verifying that data is received correctly, and re-sending any lost data. Think of it like a conversation where both parties acknowledge each other and confirm the message was received.
IP (Internet Protocol) handles addressing and routing, making sure data packets find their way to the correct destination. It's like the address on an envelope that ensures your letter reaches the right place. |

Term
|
Definition
| -a device, typically a router, that connects your local network to other networks, including the internet. |
|
|
Term
|
Definition
| -a number that helps your computer determine whether another computer is on the same local network or a different one. |
|
|
Term
| Dynamic Host Configuration Protocol (DHCP) |
|
Definition
| -automatically assigns IP addresses and other network configuration parameters to devices on a network. |
|
|
Term
|
Definition
-a numerical identifier in networking that helps direct data to the correct application on a computer.
-While an IP address gets data to the right computer, a port number ensures it reaches the right application on that computer.
-Port numbers range from 0 to 65535 |

Term
|
Definition
-like a "speed dialer" for the internet
-When you type a web address (like www.totalsem.com) into your browser, DNS translates that domain name into an IP address, allowing your computer to find and communicate with the correct server.
-This process helps you access websites without needing to remember numerical IP addresses. |

Term
| Transmission Control Protocol (TCP) |
|
Definition
-connection oriented and sends multiple packets
-involves a "handshake" process where the client and server establish a connection before data is exchanged. |
|
|
Term
| User Datagram Protocol (UDP) |
|
Definition
-connectionless protocol, but send multiple packets
-it sends data without establishing a connection first, making it faster but less reliable than TCP. |
|
|
Term
| Internet Control Message Protocol (ICMP) |
|
Definition
-a protocol used for sending error messages and operational information.
-Unlike TCP and UDP, ICMP is a single-packet protocol, meaning it sends just one packet at a time. |
|
|
Term
|
Definition
| -a device that filters and forwards data packets between computer networks, primarily based on IP addresses. |
