Hypertext Transfer Protocol (HTTP)
Mozilla Developer Network
content description: Hypertext Transfer Protocol (HTTP) is an application-layer protocol for transmitting hypermedia documents, such as HTML. It was designed for communication between web browsers and web servers, but it can also be used for other purposes. HTTP follows a classical client-server model, with a client opening a connection to make a request, then waiting until it receives a response. HTTP is a stateless protocol, meaning that the server does not keep any data (state) between two requests. Though often based on a TCP/IP layer, it can be used on any reliable transport layer; that is, a protocol that doesn't lose messages silently, such as UDP.
Organizationally Unique Identifiers (OUI)
meta description: OUI MAC address lookup tool. Supports the standard (IEEE 802) format MAC-48 addresses and the convention used by networking equipment such as Cisco.
meta description: Quick and easy MAC Address Lookups! Features include MAC address lookup, random MAC address generator, and API access to our database that you can use for whatever you want!
meta description: IEEE offers Registration Authority programs or registries which maintain lists of unique identifiers under standards and issue unique identifiers to those wishing to register them. The IEEE Registration Authority assigns unambiguous names to objects in a way which makes the assignment available to interested parties.
Protocols and Ports
meta description: A port is a communication point where one or more computers in a network talk with each other through a program or software. There are about 0-65535 ports assigned to do specific tasks in a PC. Most ports operate with TCP or UDP protocol. Port numbers are officially assigned by an organization called IANA and ports are allocated to various needs to avoid confusion.
meta description: This is a list of Internet socket port numbers used by protocols of the transport layer of the Internet Protocol Suite for the establishment of host-to-host connectivity.
our description: A list of regular expressions.
PCRE - Perl Compatible Regular Expressions
meta description: The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. PCRE has its own native API as well as a set of wrapper functions that correspond to the POSIX regular expression API.
meta description: Regular Expressions Tutorial. Comprehensive resource covering basic to advanced uses of regex. Includes regex cheat sheet, tools, books and tricks.
Request for Comments (RFC)
meta description: The RFC series contains technical and organizational documents about the Internet, including the specifications and policy documents produced by four streams: the Internet Engineering Task Force (IETF), the Internet Research Task Force (IRTF), the Internet Architecture Board (IAB), and Independent Submissions.
content description: A summary of the international standard date and time notation
NRC Official Time
meta description: As Canada's primary centre of reference for the accuracy, validity and traceability of physical and chemical measurements, NRC-INMS anchors the national measurement system and provides a fundamental technical infrastructure that supports Canadian industry and the Canadian public.
