Answer the following question: Information:  - The IBM Personal Computer, commonly known as the IBM PC, is the original version and progenitor of the IBM PC compatible hardware platform. It is IBM model number 5150, and was introduced on August 12, 1981. It was created by a team of engineers and designers under the direction of Don Estridge of the IBM Entry Systems Division in Boca Raton, Florida.  - IBM PC compatible computers are those similar to the original IBM PC, XT, and AT, able to run the same software and support the same expansion cards as those. Such computers used to be referred to as PC clones, or IBM clones. They duplicate almost exactly all the significant features of the PC architecture, facilitated by IBM's choice of commodity hardware components and various manufacturers' ability to reverse engineer the BIOS firmware using a "clean room design" technique. Columbia Data Products built the first clone of the IBM personal computer by a clean room implementation of its BIOS.  - The expansion card (also expansion board, adapter card or accessory card) in computing is a printed circuit board that can be inserted into an electrical connector, or expansion slot on a computer motherboard, backplane or riser card to add functionality to a computer system via the expansion bus.  - Columbia Data Products (CDP) is a company that produced some of the first IBM PC clones. It faltered in that market after only a few years, and later reinvented itself as a software development company.  - Clean room design (also known as the Chinese wall technique) is the method of copying a design by reverse engineering and then recreating it without infringing any of the copyrights associated with the original design. Clean room design is useful as a defense against copyright infringement because it relies on independent invention. However, because independent invention is not a defense against patents, clean room designs typically cannot be used to circumvent patent restrictions.  - The dot-com bubble (also known as the dot-com boom, the tech bubble, the Internet bubble, the dot-com collapse, and the information technology bubble) was a historic speculative bubble covering roughly 19952001 during which stock markets in industrialized nations saw their equity value rise rapidly from growth in the Internet sector and related fields. While the latter part was a boom and bust cycle, the Internet boom is sometimes meant to refer to the steady commercial growth of the Internet with the advent of the World Wide Web, as exemplified by the first release of the Mosaic web browser in 1993, and continuing through the 1990s.  - The BIOS (an acronym for Basic Input/Output System and also known as the System BIOS, ROM BIOS or PC BIOS) is a type of firmware used to perform hardware initialization during the booting process (power-on startup) on IBM PC compatible computers, and to provide runtime services for operating systems and programs. The BIOS firmware is built into personal computers (PCs), and it is the first software they run when powered on. The name itself originates from the Basic Input/Output System used in the CP/M operating system in 1975. Originally proprietary to the IBM PC, the BIOS has been reverse engineered by companies looking to create compatible systems and the interface of that original system serves as a "de facto" standard.  - A personal computer (PC) is a multi-purpose electronic computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by a person using a graphical user interface such as Windows. The versatility of a personal computer is greatly enhanced by the use of peripheral devices such as a keyboard, monitor, printer, mouse, speakers, and an external hard drive.  - The World Wide Web (abbreviated WWW or the Web) is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet. English scientist Tim Berners-Lee invented the World Wide Web in 1989. He wrote the first web browser computer program in 1990 while employed at CERN in Switzerland.  - The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a "network of networks" that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing.  - Compaq Computer Corporation was a company founded in 1982 that developed , sold , and supported computers and related products and services . Compaq produced some of the first IBM PC compatible computers , being the first company to legally reverse engineer the IBM Personal Computer . It rose to become the largest supplier of PC systems during the 1990s before being overtaken by HP in 2001 . Struggling in the aftermath of the dot - com bubble bust , Compaq was acquired for US $ 25 billion by HP in 2002 . The Compaq brand remained in use by HP for lower - end systems until 2013 when , without warning , the Compaq name was quietly discontinued . The company was formed by Rod Canion , Jim Harris and Bill Murto -- former Texas Instruments senior managers . Murto ( SVP of Sales ) departed Compaq in 1987 , while Canion ( President and CEO ) and Harris ( SVP of Engineering ) left under a shakeup in 1991 , which saw Eckhard Pfeiffer appointed President and CEO . Pfeiffer served through the 1990s . Ben Rosen provided the venture capital financing for the fledgling company and served as chairman of the board for 18 years from 1983 until September 28 , 2000 , when he retired and was succeeded by Michael Capellas , who served as the last Chairman and CEO until its merger with HP. Prior to its takeover the company was headquartered in a facility in northwest unincorporated Harris County , Texas , that now continues as HP 's largest United States facility .    Given the information, choose the subject and object entities that have the relation of 'industry'.
