"IBM PC–compatible" refers to a class of computers that are technically compatible with the 1981 IBM PC and subsequent XT and AT models from computer giant IBM. Like the original IBM PC, they use an Intel x86 central processing unit and are capable of using interchangeable commodity hardware, such as expansion cards. Initially such computers were referred to as PC clones, IBM clones or IBM PC clones, but the term "IBM PC compatible" is now a historical description only, as the vast majority of microcomputers produced since the 1990s are IBM compatible. IBM itself no longer sells personal computers, having sold its division to Lenovo in 2005. "Wintel" is a similar description that is more commonly used for modern computers.
Wintel is the partnership of Microsoft Windows and Intel producing personal computers (PCs) using Intel x86-compatible processors running Microsoft Windows.
In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of that size. A computer that uses such a processor is a 64-bit computer.
Pentium D is a range of desktop 64-bit x86-64 processors based on the NetBurst microarchitecture, which is the dual-core variant of the Pentium 4 manufactured by Intel. Each CPU comprised two cores. The brand's first processor, codenamed Smithfield and manufactured on the 90 nm process, was released on May 25, 2005, followed by the 65 nm Presler nine months later. The core implementation on the 90 nm Smithfield and later 65 nm Presler are designed differently but are functionally the same. The 90 nm Smithfield contains a single die, with two adjoined but functionally separate CPU cores cut from the same wafer. The later 65 nm Presler utilized a multi-chip module package, where two discrete dies each containing a single core reside on the CPU substrate. Neither the 90 nm Smithfield nor the 65 nm Presler were capable of direct core to core communication, relying instead on the northbridge link to send information between the two cores.
The megahertz myth, or in more recent cases the gigahertz myth, refers to the misconception of only using clock rate to compare the performance of different microprocessors. While clock rates are a valid way of comparing the performance of different speeds of the same model and type of processor, other factors such as an amount of execution units, pipeline depth, cache hierarchy, branch prediction, and instruction sets can greatly affect the performance when considering different processors. For example, one processor may take two clock cycles to add two numbers and another clock cycle to multiply by a third number, whereas another processor may do the same calculation in two clock cycles. Comparisons between different types of processors are difficult because performance varies depending on the type of task. A benchmark is a more thorough way of measuring and comparing computer performance.
The iPAQ Desktop Personal Computer in its various incarnations was a legacy-free PC produced by the Compaq Computer Corporation around the year 2000.
HP Pavilion is a line of consumer-oriented personal computers produced by HP Inc. and formerly by its predecessor, Hewlett-Packard. Introduced in 1995, HP has used the name for both desktops and laptops for home use and some home office ones. From 2002 to 2013, Compaq-branded Pavilion and Presario machines were also produced.
In computing, Intel's Advanced Programmable Interrupt Controller (APIC) is a family of programmable interrupt controllers. As its name suggests, the APIC is more advanced than Intel's 8259 Programmable Interrupt Controller (PIC), particularly enabling the construction of multiprocessor systems. It is one of several architectural designs intended to solve interrupt routing efficiency issues in multiprocessor computer systems.
The Compaq Deskpro is a line of business-oriented desktop computers manufactured by Compaq, then replaced by the Evo brand in 2001. Models were produced containing microprocessors from the 8086 up to the x86-based Intel Pentium 4. The Deskpro name, in an inverted fashion as "ProDesk", is still in use by HP, which Compaq merged with in 2002.
Presario is a discontinued line of consumer desktop computers and laptops originally produced by Compaq and later by Hewlett-Packard. Introduced in 1993, Compaq has used the Presario brand for its home and home office product offerings. HP-branded Presario machines under the Compaq brand name were produced from 2002 up until the Compaq brand name was discontinued in 2013.
Mwave was a technology developed by IBM allowing for the combination of telephony and sound card features on a single adapter card. The technology centers around the Mwave digital signal processor (DSP). The technology was used for a time to provide a combination modem and sound card for IBM's Aptiva line and some ThinkPad laptops, in addition to uses on specialized Mwave cards that handled voice recognition or ISDN networking connectivity. Similar adapter cards by third-party vendors using Mwave technology were also sold. However, plagued by consumer complaints about buggy Mwave software and hardware, IBM eventually turned to other audio and telephony solutions for its consumer products.
The Compaq Presario 1200 was a line of notebook computers produced between 1998 and 2000 by Compaq as part of Compaq Presario line.
Everex Systems, Inc., is a defunct American manufacturer of multi-processor servers, desktop and notebook personal computers. It was established in 1983 and headquartered in Fremont, California. The company was founded by Steve Hui, John Lee and Wayne Cheung. In 1988, Everex was the leader in tape backup sales with half of the world market. On January 5, 1993 the company filed for bankruptcy and was purchased by Formosa Plastics Group, hence becoming part of a multinational conglomerate alongside companies like First International Computer, the world's leading motherboard manufacturer. On December 29, 2006 Everex Systems, Inc filed a voluntary petition for liquidation under Chapter 7, and in June 2008 NewMarket Technology has taken control of Everex.
The Personal Computer Series, or PC Series, was IBM's follow-up to the Personal System/2 and PS/ValuePoint. Announced in October 1994 and withdrawn in October 2000, it was replaced by the IBM NetVista, apart from the Pentium Pro-based PC360 and PC365, which were replaced by the IBM IntelliStation.
NetVista is an umbrella name for a variety of products manufactured by IBM.
The history of laptops describes the efforts, begun in the 1970s, to build small, portable personal computers that combine the components, inputs, outputs and capabilities of a desktop computer in a small chassis.
In computing, virtualization (v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers.
The PS/1 is a brand for a line of personal computers that marked IBM's return to the home market in 1990, five years after the IBM PCjr. It was replaced by the IBM Aptiva in September 1994.
86Box is an IBM PC emulator for Windows, Linux and Mac based on PCem that specializes in running old operating systems and software that are designed for IBM PC compatibles. Originally forked from PCem, it later added support for other IBM PC compatible computers as well.
