JavaStation
The JavaStation was a Network Computer (NC) developed by Sun Microsystems between 1996 and 2000, intended to run only Java applications. The hardware is based on the design of the Sun SPARCstation series, a very successful line of UNIX workstations. The JavaStation, as an NC, lacks a hard drive, floppy or CD-ROM drive. It also differs from other Sun systems in having PS/2 keyboard and mouse interfaces and a VGA monitor connector. Models There were several models of the JavaStation produced, some being pre-production variants produced in very small numbers. Production models comprised: * JavaStation-1 (part number JJ-xx), codenamed ''Mr. Coffee'': based on a 110 MHz MicroSPARC IIe CPU, this was housed in a cuboidal Sun "unidisk" enclosure. * JavaStation-NC or JavaStation-10 (part number JK-xx) codenamed ''Krups'': a redesigned ''Mr. Coffee'' with a 100 MHz MicroSPARC IIep CPU and enhanced video resolution and color capabilities. ''Krups'' was housed in a striking ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Computer
The Network Computer (or NC) was a diskless desktop computer device made by Oracle Corporation from about 1996 to 2000. The devices were designed and manufactured by an alliance, which included Sun Microsystems, IBM, and others. The devices were designed with minimum specifications, based on the Network Computer Reference Profile. The brand was also employed as a marketing term to try to popularize this design of computer within enterprise and among consumers. The NC brand was mainly intended to inspire a range of desktop computers from various suppliers that, by virtue of their diskless design and use of inexpensive components and software, were cheaper and easier to manage than standard fat client desktops. However, due to the commoditization of standard desktop components, and due to the increasing availability and popularity of various software options for using full desktops as diskless nodes, thin clients, and hybrid clients, the Network Computer brand never achieved t ...

MediaGX
The MediaGX CPU is an x86-compatible processor that was designed by Cyrix and manufactured by National Semiconductor following the two companies' merger. It was introduced in 1997. The core is based on the integration of the Cyrix Cx5x86 CPU core with hardware to process video and audio output (XpressRAM, XpressGRAPHICS, XpressAUDIO). Following the buyout of Cyrix by National Semiconductor and the sale of the Cyrix name and trademarks to VIA Technologies, the core was developed by National Semiconductor into the Geode line of processors, which was subsequently sold to Advanced Micro Devices. Whether this processor belongs in the fourth or fifth generation of x86 processors can be considered a matter of debate as the processor was based on the 5x86 (a scaled down version of the Cyrix 6x86). While the 5x86 was intended to compete with the Intel Pentium line, the 5th generation x86, it was designed to interface with a 4th generation ( 80486) motherboard and had only the 486's instr ...

JavaOS
JavaOS is an operating system based on a Java virtual machine and predominantly used on SIM cards to run applications on behalf of operators and security services. It was originally developed by Sun Microsystems. Unlike Microsoft Windows, Windows, macOS, Unix, or Unix-like systems which are primarily written in the C (programming language), C programming language, JavaOS is primarily written in Java (programming language), Java. It is now considered a legacy system. History The Java (programming language), Java programming language was introduced by Sun in May 1995. Jim Mitchell and Peter Madany at JavaSoft designed a new operating system, codenamed Kona, written completely in Java. In March 1996, Tom Saulpaugh joined the now seven-person Kona team to design an input/output (I/O) architecture, having come from Apple as Mac OS engineer since June 1985 and co-architect of Copland (operating system), Copland. JavaOS was first evangelized in a ''Byte (magazine), Byte'' article. In 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sun Ray
The Sun Ray was a stateless thin client computer (and associated software) aimed at corporate environments, originally introduced by Sun Microsystems in September 1999 and discontinued by Oracle Corporation in 2014. It featured a smart card reader and several models featured an integrated flat panel display. The idea of a stateless desktop was a significant shift from, and the eventual successor to, Sun's earlier line of diskless Java-only desktops, the JavaStation. Predecessor The concept began in Sun Microsystems Laboratories in 1997 as a project codenamed ''NetWorkTerminal'' (NeWT). The client was designed to be small, low cost, low power, and silent. It was based on the Sun Microelectronics MicroSPARC IIep. Other processors initially considered for it included Intel's StrongARM, Philips Semiconductors' TriMedia, and National Semiconductor's Geode. The MicroSPARC IIep was selected because of its high level of integration, good performance, low cost, and availability. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MicroSPARC
The microSPARC (code-named ''Tsunami'') is a discontinued microprocessor implementing the SPARC V8 instruction set architecture (ISA), developed by Sun Microsystems. It is a low-end microprocessor intended for low-end workstations and embedded systems. The microprocessor was developed by Sun, but the floating-point unit (FPU) was licensed from Meiko Scientific. It contains 800,000 transistors. There are two derivatives of the microSPARC-II (code-named ''Swift''): the microSPARC-II and microSPARC-IIep. The microSPARC-II is used in the SPARCstation 5. The microSPARC-IIep is a 100 MHz microSPARC-II with an integrated PCI controller for embedded systems. It was developed and fabricated by LSI Logic for Sun, and used in their JavaStation Network Computer The Network Computer (or NC) was a diskless desktop computer device made by Oracle Corporation from about 1996 to 2000.

Network Computer (brand)
In computer networking, a thin client is a simple (low-performance) computer that has been optimized for establishing a remote connection with a server-based computing environment. They are sometimes known as ''network computers'', or in their simplest form as ''zero clients''. The server does most of the work, which can include launching software programs, performing calculations, and storing data. This contrasts with a rich client or a conventional personal computer; the former is also intended for working in a client–server model but has significant local processing power, while the latter aims to perform its function mostly locally. Thin clients occur as components of a broader computing infrastructure, where many clients share their computations with a server or server farm. The server-side infrastructure uses cloud computing software such as application virtualization, hosted shared desktop (HSD) or desktop virtualization (VDI). This combination forms what is know ...

Sun Workstations
The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth. The Sun's radius is about , or 109 times that of Earth. Its mass is about 330,000 times that of Earth, comprising about 99.86% of the total mass of the Solar System. Roughly three-quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron. The Sun is a G-type main-sequence star (G2V). As such, it is informally, and not completely accurately, referred to as a yellow dwarf (its light is actually white). It formed approximately 4.6 billionAll numbers in this article are short scale. One billion is 109, or 1,000,000,000. years ago from the gravitat ...

NetBSD
NetBSD is a free and open-source Unix operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems. The NetBSD project focuses on code clarity, careful design, and portability across many computer architectures. Its source code is publicly available and permissively licensed. History NetBSD was originally derived from the 4.3BSD-Reno release of the Berkeley Software Distribution from the Computer Systems Research Group of the University of California, Berkeley, via their Net/2 source code release and the 386BSD project. The NetBSD project began as a result of frustration within the 386BSD developer community with the pace and direction of the operating system's development. The four founders of the NetBSD project, Chris Demetriou, Theo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Flash Memory
Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both use the same cell design, consisting of floating gate MOSFETs. They differ at the circuit level depending on whether the state of the bit line or word lines is pulled high or low: in NAND flash, the relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate. Flash memory, a type of floating-gate memory, was invented at Toshiba in 1980 and is based on EEPROM technology. Toshiba began marketing flash memory in 1987. EPROMs had to be erased completely before they could be rewritten. NAND flash memory, however, may be erased, written, and read in blocks (or pages), which generally are much smaller than the entire device. NOR flash memory allows a single machine word to be written to an era ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
