Unified communications (UC) is a business and marketing concept describing the integration of enterprise communication services such as instant messaging (chat), presence information, voice (including IP telephony), mobility features (including extension mobility and single number reach), audio, web & video conferencing, fixed-mobile convergence (FMC), desktop sharing, data sharing (including ...
Enterprise messaging system. An enterprise messaging system (EMS) or messaging system in brief [1] is a set of published enterprise-wide standards that allows organizations to send semantically precise messages between computer systems. EMS systems promote loosely coupled architectures that allow changes in the formats of messages to have ...
The main machine in the line was the GE-225 (1961). [5] [3] It used a 20-bit word, of which 13 bits could be used for an address.Along with the basic central processing unit (CPU) the system could also have had a floating-point unit (the "Auxiliary Arithmetic Unit"), or a fixed-point decimal option with three six-bit decimal digits per word.
Instant messaging (IM), sometimes also called "messaging" or "texting", consists of computer-based human communication between two users (private messaging) or more (chat room or "group") in real-time, allowing immediate receipt of acknowledgment or reply. This is in direct contrast to email, where conversations are not in real-time, and the ...
v. t. e. The Session Initiation Protocol (SIP) is a signaling protocol used for initiating, maintaining, and terminating communication sessions that include voice, video and messaging applications. [1] SIP is used in Internet telephony, in private IP telephone systems, as well as mobile phone calling over LTE (VoLTE).
Fieldbus. A fieldbus is a member of a family of industrial digital communication networks [1] used for real-time distributed control. Fieldbus profiles are standardized by the International Electrotechnical Commission (IEC) as IEC 61784/61158. A complex automated industrial system is typically structured in hierarchical levels as a distributed ...
Telex. Telex is a telecommunication service that provides text-based message exchange over the circuits of the public switched telephone network or by private lines. The technology operates on switched station-to-station basis with teleprinter devices at the receiving and sending locations. [1]
A Computer Interface Unit allowed the DATANET-30 to communicate with a GE-200 series computer using direct memory access (DMA). It could also attach to the I/O channel of a GE-400 series, or GE-600 series system. An optional attachment allowed the DATANET-30 to attach GE-200 series peripherals such as disk storage, magnetic tape, or a line printer.
