C Programming Language
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

The Santa Cruz Operation
The Santa Cruz Operation, Inc. (usually known as SCO, pronounced either as individual letters or as a word) was an American software company, based in Santa Cruz, California, that was best known for selling three Unix operating system variants for Intel x86 processors: Xenix, SCO UNIX (later known as SCO OpenDesktop and SCO OpenServer), and UnixWare. SCO was founded in 1979 by Larry Michels and his son Doug Michels and began as a consulting and Unix porting company. An early involvement with Microsoft led to SCO making a product out of Xenix on Intel-based PCs. The fundamental insight that led to SCO's success was that there was a large market for a standard, "open systems" operating system on commodity microprocessor hardware that would give business applications computing power and throughput that previously was only possible with considerably more expensive minicomputers. SCO built a large community of value-added resellers that would eventually become 15,000 strong an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Principal causes of the 1980 recession included contractionary monetary policy undertaken by the Federal Reserve to combat double digit inflation and residual effects of the energy crisis. Manufacturing and construction failed to recover before more aggressive inflation reducing policy was adopted by the Federal Reserve in 1981, causing a second downturn. Due to their proximity and compounded effects, they are commonly referred to as the early 1980s recession, an example of a W-shaped or " double dip" recession; it remains the most recent example of such a recession in the United States.

Breakup Of The Bell System
The Bell System held a virtual monopoly over telephony infrastructure in the United States since the early 20th century until January 8, 1982. This divestiture of the Bell Operating Companies was initiated in 1974 when the United States Department of Justice filed '' United States v. AT&T'', an antitrust lawsuit against AT&T. At the time, AT&T had substantial control over the United States' communications infrastructure. Not only was it the sole telephone provider throughout most of the country, its subsidiary Western Electric produced much of its equipment. Relinquishing ownership of Western Electric was one of the Justice Department’s primary demands. AT&T Corporation proposed in a consent decree to relinquish control of the Bell Operating Companies, which had provided local telephone service in the United States. AT&T would continue to be a provider of long-distance service, while the now-independent Regional Bell Operating Companies (RBOCs), nicknamed the "Baby Bells", w ...
