A protocol for the transmission of call management and control signals in packet-based networks using H.323 equipment. The H.245 specification is used in audio, video, and data transmissions, as well as in voice over IP (VoIP). 

Media Gateway Control Protocol (MGCP), also known as H.248 and Megaco, is a standard protocol for handling the signaling and session management needed during a multimedia conference. 

H.264/MPEG-4 Part 10 or AVC (Advanced Video Coding) is a video compression format that is currently one of the most commonly used formats for the recording, compression, and distribution of video content.

High Efficiency Video Coding (HEVC), also known as H.265 is a successor to Advanced Video Coding (AVC), also known as H.264, which is one of the compression schemes used by Blu-ray. It is the latest generation video compression standard started with an idea of offering the same level of picture quality as AVC, but with better compression so that there is less data to deal with. HEVC provides superior video quality and up to twice the data compression as the previous standard.

A standard approved by the International Telecommunication Union (ITU) in 1996 to promote compatibility in videoconference transmissions over IP networks. 

H.323 is an International Telecommunication Union (ITU) standard that defines the protocols to provide audio-visual communication sessions on any packet network. H.323 was originally promoted as a way to provide consistency in audio, video and data packet transmissions in the event that a local area network (LAN) did not provide guaranteed service quality (QoS). It is widely implemented by voice and videoconferencing equipment manufacturers, is used within various Internet real-time applications such as GnuGK and NetMeeting and is widely deployed worldwide by service providers and enterprises for both voice and video services over IP networks.

Hack is an open source programming language derived from PHP for HipHop Virutal Machine (HHVM). Created by Facebook as a dialect of PHP, hack possess both static typing and dynamic typing functions, while also supplementing additional features such as generics and type aliasing.

Computer hacking is the practice of identifying gaps in computer hardware and software and using it extract, modify, or delete someone's data for personal or professionals gains, that are different from the owner's original purpose. People who engage in such activities are called Hackers.

A free, Java-based programming framework that supports the processing of large data sets in a distributed computing environment. It is part of the Apache project sponsored by the Apache Software Foundation.

A software management program that caters to salon businesses.  It keeps track of inventory, employees, clients, and appointments.

Half-duplex data transmission means that data can be transmitted in both directions on a signal carrier, but not at the same time. 

Haml (HTML Abstraction Markup Language) is a lightweight markup language that is used to describe the XHTML of any web document without the use of traditional inline coding. It is designed to address many of the flaws in traditional templating engines, as well as making markup as elegant as it can be. Haml functions as a replacement for inline page templating systems such as PHP, RHTML, and ASP.

A computer that can conveniently be stored in a pocket (of sufficient size) and used while you're holding it. 

A language that allows the text portions of Web pages to be presented on cellular telephones and personal digital assistants (PDA) via wireless access. 

A typedef supplied in the Windows headers files. A typedef can be thought of as an alias or pseudonym. In the Windows registry, a handle represents an open instance of a basic operating system object with which applications interact. 

A full-featured portable computer that is slightly larger than a PDA, but much smaller than a laptop. It offers hardware, software, performance, and display capabilities.
