William Crowther (programmer)
William Crowther (born 1936) is an American computer programmer, caver, and rock climber. He is the co-creator of ''Colossal Cave Adventure'' from 1975 onward, a seminal computer game that influenced the first decade of video game design and inspired the text adventure game genre. Biography During the early 1970s, Crowther worked at defense contractor and internet pioneer Bolt Beranek and Newman (BBN), where he was part of the original small ARPAnet development team. His implementation of a distributed distance vector routing system for the ARPAnet was an important step in the evolution of the internet. Crowther met and married Pat Crowther while studying at the Massachusetts Institute of Technology, where he received a B.S. in physics in 1958. Adventure Following his divorce from his wife, Crowther used his spare time to develop a text-based adventure game in Fortran on BBN's PDP-10. He created it as a diversion his daughters Sandy and Laura could enjoy when they came ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ARPANET
The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense. Building on the ideas of J. C. R. Licklider, Bob Taylor initiated the ARPANET project in 1966 to enable access to remote computers. Taylor appointed Larry Roberts as program manager. Roberts made the key decisions about the network design. He incorporated Donald Davies' concepts and designs for packet switching, and sought input from Paul Baran. ARPA awarded the contract to build the network to Bolt Beranek & Newman who developed the first protocol for the network. Roberts engaged Leonard Kleinrock at UCLA to develop mathematical methods for analyzing the packet network technology. The first ...

CP/M
CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/ 85-based microcomputers by Gary Kildall of Digital Research, Inc. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors. The combination of CP/M and S-100 bus computers became an early standard in the microcomputer industry. This computer platform was widely used in business through the late 1970s and into the mid-1980s. CP/M increased the market size for both hardware and software by greatly reducing the amount of programming required to install an application on a new manufacturer's computer. An important driver of software innovation was the advent of (comparatively) low-cost microcomputers running CP/M, as independent programmers and hackers bought them and shared their crea ...

Operating Systems
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and th ...

Bedquilt
A quilt is a multi-layered textile, traditionally composed of two or more layers of fabric or fiber. Commonly three layers are used with a filler material. These layers traditionally include a woven cloth top, a layer of batting or wadding, and a woven back combined using the techniques of quilting. This is the process of sewing on the face of the fabric, and not just the edges, to combine the three layers together to reinforce the material. Stitching patterns can be a decorative element. A single piece of fabric can be used for the top of a quilt (a "whole-cloth quilt"), but in many cases the top is created from smaller fabric pieces joined, or patchwork. The pattern and color of these pieces creates the design. Quilts may contain valuable historical information about their creators, "visualizing particular segments of history in tangible, textured ways." In the twenty-first century, quilts are frequently displayed as non-utilitarian works of art but historically quilts were ...

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 length and slightly extending the instruction set (but with 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, MIT's AI Lab and Project MAC, Stanford's SAIL, Computer ...
