Protocols Flashcards
What is a protocol?
A protocol is a set of rules that allow devices on a network to communicate with each other.
Explain the TCP/IP Protocol
TCP is a protocol that allows packets to be sent and received between computer systems. It breaks the data into packets and reassembles them into the original data at the destination.
IP is a protocol that sets out the format of packets and it is an addressing system (a unique IP address) for devices on a network.
Explain the HTTP Protocol
HTTP is a protocol than can be used to transfer web pages over the Internet so that users can view them in a web browser.
HTTPS is a secure version of HTTP that works with another protocol (Secure Socket Layers (SSL)). You will should see a lock symbol in your URL bar if your connection to that website is secure.
Explain the FTP Protocol
FTP is a protocol that can be used when copying a file from one location to another via a network or the Internet. It is typically used for the transfer of large files, as it allows broken communications to resume transferring a file rather than having to restart.
Explain the connection protocols (Ethernet and Wifi)
Ethernet is a protocol for wired connections that use cables such as copper or fibre optic.
WiFi is a protocol for wireless connections, such as Bluetooth.
Explain the Email Protocols
Simple Mail Transfer Protocol (SMTP) is a protocol used by email applications for sending messages to a mail server.
Post Office Protocol 3 (POP3) is a protocol for receiving emails, in which email is received and stored by an email server until a client downloads messages when ready.
Internet Message Access Protocol (IMAP) is a protocol that transfers emails between computer systems via the internet. IMAP is generally used as an alternative to POP.
