WOW! (online Service)
CompuServe, Inc. (CompuServe Information Service, Inc., also known by its initialism CIS or later CSi) was an American Internet company that provided the first major commercial online service. It opened in 1969 as a timesharing and remote access service marketed to corporations. After a successful 1979 venture selling otherwise under-utilized after-hours time to Radio Shack customers, the system was opened to the public, roughly the same time as The Source. H&R Block bought the company in 1980 and began to advertise the service aggressively. CompuServe dominated the industry during the 1980s, buying their competitor The Source. One popular use of CompuServe during the 1980s was file exchange, particularly pictures. In 1985, it hosted one of the earliest online comics, '' Witches and Stitches''. CompuServe introduced a simple black-and-white image format known as RLE (run-length encoding) to standardize the images so they could be shared among different types of microcomputers. W ...

Steve Wilhite
Stephen Earl Wilhite (March 3, 1948 – March 14, 2022) was an American computer scientist who worked at CompuServe and was the engineering lead on the team that created the GIF image file format in 1987. GIF went on to become the de facto standard for 8-bit color images on the Internet until PNG (1996) became a widely supported alternative. The format later became the subject of a patent assertion by Unisys on its use of the LZW compression algorithm. Known as the inventor or creator of the GIF, Wilhite received a Webby Lifetime Achievement Award in 2013. Biography Stephen Earl Wilhite was born in West Chester Township, Ohio, on March 3, 1948, the son of Anna Lou (Dorsey), a nurse, and Clarence Earl Wilhite, a factory worker. Wilhite's team at CompuServe developed the GIF (Graphic Interchange Format) in 1987. Its adoption by the earliest web browser in 1991 helped make it a few years later in 1995 the most popular image file format. Twenty years later in 2016, the format s ...

Midrange Computer
Midrange computers, or midrange systems, were a class of computer systems that fell in between mainframe computers and microcomputers. This class of machine emerged in the 1960s, with models from Digital Equipment Corporation ( PDP lines), Data General ( NOVA), and Hewlett-Packard (HP 2100 and HP 3000) widely used in science and research as well as for business - and referred to as minicomputers. IBM favored the term "midrange computer" for their comparable, but more business-oriented systems. IBM midrange systems * System/3 (1969) was the first IBM midrange system. * System/32 (introduced in 1975) was a 16-bit single-user system also known as the IBM 5320. * System/34 (1977) was intended to be a successor to both the 3 and the 32. It had two 16-bit processors and ran the SSP operating system. * System/38 (1979) was the first midrange system to have an integrated relational database management system (DBMS). The S/38 had 48-bit addressing, and ran the CPF operating ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PDP-10
Digital Equipment Corporation (DEC)'s PDP-10, later marketed as the DECsystem-10, is a mainframe computer family manufactured beginning in 1966 and discontinued in 1983. 1970s models and beyond were marketed under the DECsystem-10 name, especially as the TOPS-10 operating system became widely used. The PDP-10's architecture is almost identical to that of DEC's earlier PDP-6, sharing the same 36-bit Word (computer architecture), word length and slightly extending the instruction set. The main difference was a greatly improved hardware implementation. Some aspects of the instruction set are unusual, most notably the ''byte'' instructions, which operate on bit fields of any size from 1 to 36 bits inclusive, according to the general definition of a byte as ''a contiguous sequence of a fixed number of bits''. The PDP-10 was found in many university computing facilities and research labs during the 1970s, the most notable being Harvard University's Aiken Computation Laboratory, Mass ...

Time-sharing
In computing, time-sharing is the Concurrency (computer science), concurrent sharing of a computing resource among many tasks or users by giving each Process (computing), task or User (computing), user a small slice of CPU time, processing time. This quick switch between tasks or users gives the illusion of Parallel computing, simultaneous execution. It enables computer multitasking, multi-tasking by a single user or enables multiple-user sessions. Developed during the 1960s, its emergence as the prominent model of computing in the 1970s represented a major technological shift in the history of computing. By allowing many users to interact concurrent computing, concurrently with a single computer, time-sharing dramatically lowered the cost of providing computing capability, made it possible for individuals and organizations to use a computer without owning one, and promoted the Interactive computing, interactive use of computers and the development of new interactive application ...
