  1. Coherent

    The Coherent operating system was a Version 7 Unix clone by the now-defunct Mark Williams Company, originally produced for the PDP-11 in 1980. A port was introduced in 1983 as the first Unix-like system for IBM PC compatible computers. Coherent was able to run on most Intel-based PCs with Intel 8088, 286, 386, and 486 processors. Coherent version 3 for Intel-based PCs required at least a 286, Coherent version 4 for Intel-based PCs required at least a 386. Like a true Unix, Coherent was able to multitask and support multiple users. From version 4 on Coherent also had support for X11 and MGR windowing systems. Later versions of Coherent supported features common in modern Unix-like systems, including a version of MicroEMACS, access to DOS FAT16 File systems, an optimizing C compiler with linker, and a modified version of Taylor UUCP. The final releases of Coherent also fully supported the iBCS COFF binary standard, which allowed binary compatibily with SCO Unix applications, including WordPerfect, Lotus 1-2-3, and several Microsoft applications including QuickBASIC, Microsoft Word, and MultiPlan. There was no support for virtual memory or demand paging. Coherent predates both MINIX and Linux by many years.

Examples of coherent in a Sentence

    Humans by nature are always bound to set goals for them which eventually fulfill their needs and desires. It is the force that drives them to achieve more. But moving in the right direction to achieve is usually uncommon because most of the people wish to achieve more in less time and rush to reach the success, thus just work in a cluttered way.

Because Process leads you to your goal step by step.
