Stanford University Network
The Stanford University Network, also known as SUN, SUNet or SU-Net is the campus computer network for Stanford University. History Stanford Research Institute, formerly part of Stanford but on a separate campus, was the site of one of the four original ARPANET nodes. Later ARPANET nodes were located in the Stanford Artificial Intelligence Laboratory, the Computer Science Department, and the Stanford University Medical Center. In late 1979, the Xerox Palo Alto Research Center donated equipment including Xerox Alto computers, a laser printer, and file server connected by Ethernet local area network technology. CSL Technical Report 229 (First author name is misspelled on cover) A router based on the PDP-11 computer from Digital Equipment Corporation with software from MIT was used to connect the Ethernet to the ARPANET. The PARC Universal Packet protocol was initially used on the local parts of the network, which was the experimental version of Ethernet with a data rate under 3 m ...

Computer Network
A computer network is a set of computers sharing resources located on or provided by network nodes. The computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies, based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies. The nodes of a computer network can include personal computers, servers, networking hardware, or other specialised or general-purpose hosts. They are identified by network addresses, and may have hostnames. Hostnames serve as memorable labels for the nodes, rarely changed after initial assignment. Network addresses serve for locating and identifying the nodes by communication protocols such as the Internet Protocol. Computer networks may be classified by many criteria, including the transmission medium used to carry signals, bandwidth, communications pro ...

SUN Workstation
The SUN workstation was a modular computer system designed at Stanford University in the early 1980s. It became the seed technology for many commercial products, including the original workstations from Sun Microsystems. History In 1979 Xerox donated some Alto computers, developed at their Palo Alto Research Center, to Stanford's Computer Science Department, as well as other universities that were developing the early Internet. The Altos were connected using Ethernet to form several local area networks. The SUN's design was inspired by that of the Alto, but used lower-cost modular components. (Many words are spelled phonetically) The project name was derived from the initials of the campus' Stanford University Network. CSL Technical Report 229 (First author name is misspelled on cover) Professor Forest Baskett suggested the best-known configuration: a relatively low-cost personal workstation for computer-aided logic design work. The design created a 3M computer: a 1 million inst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cisco IOS
The Internetworking Operating System (IOS) is a family of proprietary network operating systems used on several router and network switch models manufactured by Cisco Systems. The system is a package of routing, switching, internetworking, and telecommunications functions integrated into a multitasking operating system. Although the IOS code base includes a cooperative multitasking kernel, most IOS features have been ported to other kernels, such as Linux and QNX, for use in Cisco products. Not all Cisco networking products run IOS. Exceptions include some Cisco Catalyst switches, which run IOS XE, and Cisco ASR routers, which run either IOS XE or IOS XR; both are Linux-based operating systems. For data center environments, Cisco Nexus switches (Ethernet) and Cisco MDS switches ( Fibre Channel) both run Cisco NX-OS, also a Linux-based operating system. History The IOS network operating system was created from code written by William Yeager at Stanford University, which w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C (programming Language)
C (''pronounced like the letter c'') is a General-purpose language, general-purpose computer 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 CPUs. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for application software. 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 measuring programming language popularity, most widely used programming languages, with C compilers avail ...

William Yeager
William "Bill" Yeager (born June 16, 1940, San Francisco) is an American engineer. He is best known for being the inventor of a packet-switched, "Ships in the Night," multiple-protocol router in 1981, during his 20-year tenure at Stanford's Knowledge Systems Laboratory as well as the Stanford University Computer Science department. The code routed Parc Universal Packet (PUP), XNS, IP and CHAOSNet. The router used Bill's Network Operating System (NOS). The NOS also supported the EtherTIPS that were used throughout the Stanford LAN for terminal access to both the LAN and the Internet. This code was licensed by Cisco Systems in 1987 and comprised the core of the first Cisco IOS. This provided the groundwork for a new, global communications approach. He is also known for his role in the creation of the IMAP mail protocol. In 1984 he conceived of a client/server protocol, designed its functionality, applied for and received the grant money for its implementation. In 1985 Mark Crisp ...
