An IBM PC compatible is any personal computer that is hardware- and software-compatible with the IBM Personal Computer (IBM PC) and its subsequent models. Like the original IBM PC, an IBM PC–compatible computer uses an x86-based central processing unit, sourced either from Intel or a second source like AMD, Cyrix or other vendors such as Texas Instruments, Fujitsu, OKI, Mitsubishi or NEC and is 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.

The designation "PC", as used in much of personal computer history, has not meant "personal computer" generally, but rather an x86 computer capable of running the same software that a contemporary IBM or Lenovo PC could. The term was initially in contrast to the variety of home computer systems available in the early 1980s, such as the Apple II, TRS-80, and Commodore 64. Later, the term was primarily used in contrast to Commodore's Amiga and Apple's Macintosh computers.

The Digital Display Working Group (DDWG) was a technological consortium whose purpose was to define and maintain the Digital Visual Interface standard, which was formed in 1998.

TravelMate is a line of business-oriented laptop computers manufactured by Acer. Of the various notebook series Acer has offered, the TravelMate is designated as a lightweight business and professional computer built to withstand day-to-day activities. TravelMate laptops are well received by reviewers, often, however, they are faulted for a lack of visual appeal. The TravelMate name was previously used by Texas Instruments, which sold its mobile computing division to Acer in 1997. The TravelMate mainly competes against business computers such as Asus's ExpertBook, Dell's Latitude and Vostro, Fujitsu's LifeBook, HP's EliteBook and ProBook, Lenovo's ThinkPad and ThinkBook, and Toshiba's Portégé and Tecra.

Dell Latitude is a line of laptop computers manufactured and sold by American company Dell Technologies. It is a business-oriented line, aimed at corporate enterprises, healthcare, government, and education markets; unlike the Inspiron and XPS series, which were aimed at individual customers, and the Vostro series, which was aimed at smaller businesses. The Latitude line directly competes with Acer's Extensa and TravelMate, Asus's ExpertBook, Fujitsu's LifeBook, HP's EliteBook and ProBook, Lenovo's ThinkPad and ThinkBook and Toshiba's Portégé and Tecra. The "Rugged (Extreme)", "XFR" and "ATG" models compete primarily with Panasonic's Toughbook line of "rugged" laptops.

In January 2025, Dell announced its intentions to gradually phase out their existing lineup of computer brands in favor of a singular brand simply named as "Dell" as part of the company's shift towards the next generation of PCs with artificial intelligence capabilities. The Latitude brand would be supplanted by the Dell Pro laptop line, which emphasizes professional-grade productivity and business-class computers.

HP EliteBook is a line of business-oriented laptop computers made by Hewlett-Packard (HP Inc.), marketed as a high-end line positioned above the ProBook series. The line was introduced in August 2008 as a replacement to the HP Compaq line of business laptops, and initially included mobile workstations until September 2013, when they were rebranded as HP ZBook. The EliteBook mainly competes against laptop computers such as Acer's Extensa and TravelMate, Asus's ExpertBook, Dell's Latitude and Vostro, Fujitsu's LifeBook, Lenovo's ThinkPad and ThinkBook and Toshiba's Portégé and Tecra.
