DoD- Department of defense
The Advanced Research Projects Agency-Energy (ARPA-E) advances high-potential, high-impact energy technologies that are too early for private-sector investment. ARPA-E awardees are unique because they are developing entirely new ways to generate, store, and use energy.
ARPA- Advanced research project Agency
The ITU Telecommunication Standardization Sector (ITU-T) coordinates standards for telecommunications and Information Communication Technology such as X. 509 for cybersecurity, Y. 3172 and Y. … The standardization efforts of ITU started in 1865 with the formation of the International Telegraph Union (ITU).
ITU-T- International Telecommunication Agency- Telecommunication sector
The American National Standards Institute is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States.
ANSI- American National Standard Institute
The International Organization for Standardization (ISO) is an international nongovernmental organization made up of national standards bodies; it develops and publishes a wide range of proprietary, industrial, and commercial standards and is comprised of representatives from various national standards organizations.
ISO- International Organization for Standardization- responsible for OSI Model
The open systems interconnection (OSI) model is a conceptual model created by the International Organization for Standardization which enables diverse communication systems to communicate using standard protocols.
OSI- Open System Interconnection
In telecommunications, a protocol data unit is a single unit of information transmitted among peer entities of a computer network. A PDU is composed of protocol-specific control information and user data.
PDU- Protocol Data unit- what data is called
The Simple Mail Transfer Protocol is an internet standard communication protocol for electronic mail transmission. Mail servers and other message transfer agents use SMTP to send and receive mail messages.
SMTP- Simple Mail Transfer Protocol- the server you would send the mail to- uses TCP
POP3 is a one-way client-server protocol in which email is received and held on the email server. The “3” refers to the third version of the original POP protocol. A recipient or their email client can download mail periodically from the server using POP3.
POP3- Post Office Protocol version 3- the server you would retrieve the mail from- uses TCP
IMAP4 stands for Internet Mail Access Protocol version 4, is an Internet standard protocol for storing and retrieving messages from Simple Mail Transfer Protocol (SMTP) hosts.
IMAP4- Internet Message Access protocol version 4- the server you would retrieve the mail from (keeps
a copy of the mail)- uses TCP
Usage. SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding TCP ports and X11 connections; it can transfer files using the associated SSH file transfer (SFTP) or secure copy (SCP) protocols. SSH uses the client–server model.
SSH- Secure Shell- encrypted remote access- uses TCP
Hypertext Transfer Protocol (often abbreviated to HTTP) is a communications protocol. It is used to send and receive webpages and files on the internet. It was developed by Tim Berners-Lee and is now coordinated by the W3C. HTTP version 1.1 is the most common used version today.
HTTP- Hyper Text Transfer protocol- Transfer HTML (Hyper Text Markup Language) from a Web server to
a browser- uses TCP
Hypertext Transfer Protocol Secure is an extension of the Hypertext Transfer Protocol. It is used for secure communication over a computer network, and is widely used on the Internet. In HTTPS, the communication protocol is encrypted using Transport Layer Security or, formerly, Secure Sockets Layer.
HTTPS- Hyper Text Transfer Protocol Secure- Same as HTTP, by data is encrypted in transit- uses TCP
The World Wide Web, commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators, which may be interlinked by hyperlinks, and are accessible over the Internet.
WWW- World Wide Web- Hold HTML pages- use TCP
Domain Name System (DNS) is a hierarchical naming system built on a distributed database for computers, services, or any resource connected to the Internet or a private network.
DNS- Domain Naming Service- Translates names to destination IP addresses- uses TCP or UDP
