Video Graphics Array (VGA) is a video display controller and accompanying de facto graphics standard, first introduced with the IBM PS/2 line of computers in 1987, which became ubiquitous in the IBM PC compatible industry within three years. The term can now refer to the computer display standard, the 15-pin D-subminiature VGA connector, or the 640 × 480 resolution characteristic of the VGA hardware.
The Apple IIe Card is a compatibility card, which through hardware and software emulation, allows certain Macintosh computers to run software designed for the Apple II. Released in March 1991 for use with the LC family, Apple targeted the card at its widely dominated educational market to ease the transition from Apple II-based classrooms, with thousands of entrenched educational software titles, to Macintosh-based classrooms.
The Transmeta Crusoe is a family of x86-compatible microprocessors developed by Transmeta and introduced in 2000.
The Athlon 64 is a ninth-generation, AMD64-architecture microprocessor produced by Advanced Micro Devices (AMD), released on September 23, 2003. It is the third processor to bear the name Athlon, and the immediate successor to the Athlon XP. The Athlon 64 was the second processor to implement the AMD64 architecture and the first 64-bit processor targeted at the average consumer. Variants of the Athlon 64 have been produced for Socket 754, Socket 939, Socket 940, and Socket AM2. It was AMD's primary consumer CPU, and primarily competed with Intel's Pentium 4, especially the Prescott and Cedar Mill core revisions.
x86-64 is a 64-bit version of the x86 instruction set, first announced in 1999. It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new 4-level paging mode.
Memory-mapped I/O (MMIO) and port-mapped I/O (PMIO) are two complementary methods of performing input/output (I/O) between the central processing unit (CPU) and peripheral devices in a computer. An alternative approach is using dedicated I/O processors, commonly known as channels on mainframe computers, which execute their own instructions.
In computing, Physical Address Extension (PAE), sometimes referred to as Page Address Extension, is a memory management feature for the x86 architecture. PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. It defines a page table hierarchy of three levels (instead of two), with table entries of 64 bits each instead of 32, allowing these CPUs to directly access a physical address space larger than 4 gigabytes (232 bytes).
The X68000 is a home computer created by Sharp Corporation. It was first released in 1987 and sold only in Japan.
ArtRage is a bitmap graphics editor for digital painting created by Ambient Design Ltd. It is currently in version 6, and supports Windows, macOS and mobile Apple and Android devices and is available in multiple languages. It caters to all ages and skill levels, from children to professional artists. ArtRage 5 was announced in January 2017 and released in February 2017.
QEMU is a free and open-source emulator that uses dynamic binary translation to emulate the processor of a computer. It provides a variety of hardware and device models for the machine, enabling it to run different guest operating systems. QEMU can be used in conjunction with Kernel-based Virtual Machine (KVM) to execute virtual machines at near-native speeds. Additionally, QEMU supports the emulation of user-level processes, allowing applications compiled for one processor architecture to run on another.
In computer security, executable-space protection marks memory regions as non-executable, such that an attempt to execute machine code in these regions will cause an exception. It makes use of hardware features such as the NX bit, or in some cases software emulation of those features. However, technologies that emulate or supply an NX bit will usually impose a measurable overhead while using a hardware-supplied NX bit imposes no measurable overhead.
The Sun386i is a discontinued hybrid UNIX workstation/PC compatible computer system produced by Sun Microsystems, launched in 1988. It is based on the Intel 80386 microprocessor but shares many features with the contemporary Sun-3 series systems.
The Tektronix 4050 is a series of three desktop computers produced by Tektronix in the late 1970s through the early 1980s. The display technology is similar to the Tektronix 4010 terminal, using a storage tube display to avoid the need for video RAM. They are all-in-one designs with the display, keyboard, CPU and DC300 tape drive in a single desktop case. They also include a GPIB parallel bus interface for controlling lab and test equipment as well as connecting to external peripherals. A simple operating system and BASIC interpreter are included in ROM.
The ASUS Eee PC is a netbook computer line from Asus, and a part of the ASUS Eee product family. At the time of its introduction in late 2007, it was noted for its combination of a lightweight, Linux-based operating system, solid-state drive (SSD), and relatively low cost. Newer models added the options of Microsoft Windows operating system and rotating media hard disk drives (HDD), and initially retailed for up to 500 euros.
The OLPC XO is a low cost laptop computer intended to be distributed to children in developing countries around the world, to provide them with access to knowledge, and opportunities to "explore, experiment and express themselves". The XO was developed by Nicholas Negroponte, a co-founder of MIT's Media Lab, and designed by Yves Behar's Fuseproject company. The laptop is manufactured by Quanta Computer and developed by One Laptop per Child (OLPC), a non-profit 501(c)(3) organization.
Dell Vostro is a line of business-oriented laptop and desktop computers manufactured by Dell aimed at small to medium range businesses. From 2013–2015, the line was temporarily discontinued on some Dell websites but continued to be offered in other markets, such as Malaysia and India.
Windows XP, which is the next version of Windows NT after Windows 2000 and the successor to the consumer-oriented Windows Me, has been released in several editions since its original release in 2001.
The maximum random access memory (RAM) installed in any computer system is limited by hardware, software and economic factors. The hardware may have a limited number of address bus bits, limited by the processor package or design of the system. Some of the address space may be shared between RAM, peripherals, and read-only memory. In the case of a microcontroller with no external RAM, the size of the RAM array is limited by the size of the integrated circuit die. In a packaged system, only enough RAM may be provided for the system's required functions, with no provision for addition of memory after manufacture.
The eXtended Graphics Array is a graphics card manufactured by IBM and introduced for the IBM PS/2 line of personal computers in 1990 as a successor to the 8514/A. It supports, among other modes, a display resolution of 1024 × 768 pixels with 256 colors at 43.5 Hz (interlaced), or 640 × 480 at 60 Hz (non-interlaced) with up to 65,536 colors. The XGA-2 added an 800 × 600 65,536 color mode and 1024 × 768 60 Hz non-interlaced.
The ThinkPad X series is a line of laptop computers and convertible tablets produced by Lenovo with less power than its other counterparts. It was initially produced by IBM until 2005.
