Operations Support System
Operations support systems (OSS), operational support systems in British usage, or Operation System (OpS) in Nippon Telegraph and Telephone, NTT are computer systems used by telecommunications service providers to manage their networks (e.g., telephone networks). They support management functions such as inventory, network inventory, service provisioning, configuration management, network configuration and fault management. Together with business support systems (BSS), operations support systems support various end-to-end telecommunication services. BSS and OSS have their own data and service responsibilities. The two systems together are often abbreviated OSS/BSS, BSS/OSS or simply B/OSS. The acronym OSS is also used in a singular form to refer to all the Operations Support Systems viewed as a whole system. Different subdivisions of OSS have been proposed by the TM Forum, industrial research labs, or OSS vendors. In general, an OSS covers at least the following five functions: * ...

Computer System
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of compute ...

Bell Labs Record
''Bell Laboratories Record'' (BLR) was a publication of the ''Bureau of Publication'' of the American Telephone and Telegraph Company (AT&T) and Bell Laboratories. It commenced distribution as a house organ for the employees and associates of the laboratories and the Bell System in September 1925, shortly after the founding of Bell Labs as a separate corporate entity. The first ''Director of Publication'' was John Mills, leading three managing and assisting editors, and an eleven-member editorial advisory board. The magazine reported personal, scientific, and organizational information, scholarly articles, and news of interest within the laboratories, Western Electric, and AT&T. It included descriptions of technologies created at many Bell System locations for basic research, devices, technologies, systems, and operations research relevant to telephone company, manufacturing, and government applications. It was slimmer and less scholarly than the '' Bell Labs Technical Journal''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
