Microprocessors made by Intel Corporation form the foundation of all PCs.
Models after the 8086 are often referred to by the last three digits (for example, the 286, 386, and 486 ). Many of the microprocessors come in different varieties that run at various clock rates. The 80486 architecture, for example, supports clock rates of from 33 to 66 MHz. Because Intel discovered that it couldn’t trademark its CPU numbers, it shifted to a naming scheme, starting with the Pentium processors. Intel’s latest and sixth-generation chip is called the Pentium Pro.
All Intel microprocessors are backward compatible, which means that they can run programs written for a less powerful processor. The 80386, for example, can run programs written for the 8086, 8088, and 80286. The 80386 and later models, however, offer special programming features not available on previous models. Software written specifically for these processors, therefore, may not run on older microprocessors. The common architecture behind all Intel microprocessors is known as the x86 architecture.
Until the late 80s, Intel was essentially the only producer of PC microprocessors. Increasingly, however, Intel is facing competition from other manufacturers who produce “Intel-compatible ” chips. These chips support the Intel instruction set and are often less expensive than Intel chips. In some cases, they also offer better performance. Two of the leading manufacturers of Intel-compatible chips are Cyrix and AMD.

- Intelligent Exposure
In digital camera terminology, Intelligent Exposure is a function of the camera that helps to avoid blown highlights and blocked shadows by suppressing the extreme brightness and darkness in the picture. This function works by partially controlling the ISO sensitivity to increase the exposure of only the darkened area when there is backlighting or insufficient […]
- Intelligent Platform Management Interface
Abbreviated as IPMI, the Intelligent Platform Management Interface is a remote hardware health monitoring and management system that defines interfaces for use in monitoring the physical health of servers, such as temperature, voltage, fans, power supplies and chassis. It was developed by Dell, HP, Intel and NEC, but has many more industry promoters, adopters and […]
- Intelligent Printer Data Stream
Intelligent Printer Data Stream (IPDS) is the host-to-printer data stream used by IBM’s System Application Architecture (SAA) for Advanced Function Printing (AFP). The IPDS architecture defines the data stream used by print server programs and device drivers to manage all-points-addressable page printing on a full spectrum of devices from low-end workstation and local area network-attached […]
Short for Internet Network Information Center, a registered service mark of the U.S. Department of Commerce and now a defunct entity. InterNIC began as a collaborative project between AT&T and Network Solutions, Inc. (NSI) supported by the National Science Foundation. When active, the project offered four services: InterNIC Directory and Database Services — online white […]
