Internet Protocol (IP): The principal communications protocol in the internet protocol suite that is used to route information over the Internet. Transmission Control Protocol (TCP): An important protocol in the internet protocol suite that enables two hosts to establish a connection and exchange data. User Datagram Protocol (UDP): An important protocol in the internet protocol suite that is generally used when speed in transmission is more important than accuracy since the sending computer doesn't verify that the packets were correctly received.

Domain Name System (DNS): A protocol that helps internet users and network devices discover other devices using a human-readable hostname instead of numeric IP addresses. Hypertext Transfer Protocol (HTTP): A protocol that governs the transfer of web content between computers. Hypertext Transfer Protocol Secure (HTTPS): A protocol that combines HTTP with the Secure Sockets Layer (SSL) protocol to securely transfer web content between computers. TESTOUT IT FUNDAMENTALS PRO

Simple Mail Transfer Protocol (SMTP): A protocol used to send email. Post Office Protocol 3 (POP 3): A protocol used to receive email. With POP 3, email is deleted from a server after it is downloaded to a client. Internet Message Access Protocol (IMAP): A protocol used to receive email. With IMAP, email is saved on a server even after it is downloaded to a client. TESTOUT IT FUNDAMENTALS PRO

HTTP Method: A command that tells the server what the user wants to do. The most common methods are POST, GET, PATCH, and DELETE. These methods are used for CRUD operations which stand for Create, Read, Update, and Delete. Dynamic Host Configuration Protocol (DHCP): A network management protocol that assigns IP addresses on a network. It is part of the larger set of built-in networking protocols known as TCP/IP.

Subnetting: Dividing a network into smaller subnets. Subnet Mask: A value given to an address in a subnetted network that tells a computer which numbers are part of the network or subnet address and which are part of the host address. TESTOUT IT FUNDAMENTALS PRO
