Why ibm compatible are duplicate of ibm pc

The computers designed as well as developed by IBM Corporation are called IBM PC. The computers which are designed by IBM but manufactured by companies other then IBM are called IBM Compatibles. It is also known as original or branded IBM.

IBM-compatible A computer functionally identical to an IBM PC and able to accept all hardware and software intended for it. This was an important concept in the early 1980s when the IBM PC was emerging from among a number of other contenders as the one to copy.

This created numerous headaches for unsuspecting end users. Some systems offered the capability to run both CP/M and MS-DOS. The first company to successfully build a 100% compatible IBM PC clone was Compaq computer, who introduced their first system as what they called a portable.

“IBM PC Compatible” is a misnomer. No modern machine is IBM PC compatible in any significant way: Processor: The IBM PC used an 8086 processor. All modern machines set the processor to i386 at bootup and never use anything else except for for DOS programs, by virtualizing.

In Season One, we are introduced to Cardiff Electric, a software company loosely based on Compaq. Compaq was a Texas-based computer company (now defunct) that was founded in 1982. It is known for being the first company to reverse engineer the IBM Personal Computer.

But these competitors had all made a fatal mistake: Copying IBM’s code, at which point IBM would sue. Compaq, which was based in Houston instead of Silicon Valley or New York, flew under the radar. … “If they had looked at it, then they would have been sued.” That fall, Compaq released the Compaq Portable.

A Mac is designed for personal use and is a computer, so that makes it is a PC. However, when IBM introduced their first computer in August 1981, model number 5150, the term PC became something more specific. … By this definition, a Mac computer is not a PC, as it is not IBM-compatible.

“As the first IBM PC clone, the MPC was actually superior to the IBM original. It came with 128 KiB RAM standard, compared to the IBM’s 64 KiB maximum. The MPC had eight PC expansion slots, with one filled by its video card. Its floppy disk drive interface was built into the motherboard.

Columbia personal computer

This was the first IBM PC clone, offering more memory and expansion slots. Columbia avoided a copyright lawsuit by having its engineers recreate equivalent BIOS software in a “clean room” environment without looking at IBM’s code.

What Does Linux PC Mean? A Linux PC is a personal computer that comes pre-installed with the open-source Linux operating system (OS).

A laptop, laptop computer, or notebook computer is a small, portable personal computer (PC) with a screen and alphanumeric keyboard.

…on its first microcomputer, the IBM PC (personal computer). After the machine’s release in 1981, IBM quickly set the technical standard for the PC industry, and MS-DOS likewise pushed out competing operating systems.

IBM still makes computers

IBM still manufactures and services mainframes like this Z10. It surprises some people to hear, but IBM still makes computers. They don’t make computers that run Windows, but they still make high-end computers that run AIX, their version of Unix. They also make minicomputers and mainframes.

In the early 1990s, IBM made a painful transition from selling computers to selling services and software. … For a time, IBM kept selling PCs because it made it easier to sell services. But eventually that stopped being enough of an advantage, so IBM sold off its PC line in 2005 to Lenovo.

IBM, in full International Business Machines Corporation, leading American computer manufacturer, with a major share of the market both in the United States and abroad. Its headquarters are in Armonk, New York.

First Computers

The first substantial computer was the giant ENIAC machine by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC (Electrical Numerical Integrator and Calculator) used a word of 10 decimal digits instead of binary ones like previous automated calculators/computers.

English mathematician and inventor Charles Babbage is credited with having conceived the first automatic digital computer. During the mid-1830s Babbage developed plans for the Analytical Engine. Although it was never completed, the Analytical Engine would have had most of the basic elements of the present-day computer.
