History of Unix:<\/h3>\n
    \n
  • In 1965, Bell Laboratories joined with MIT and General Electric in the development project – Multics.<\/li>\n
  • In 1969 Ken Thompson, Dennis Ritchie, Rudd Canaday, and Doug McIlroy implemented the first version of the Unix at University of California at Berkley.<\/li>\n
  • The name UNIX was given by Brian Kernighan.<\/li>\n
  • In 1989, AT&T and Sun Microsystems joined together and developed system V release 4 (SVR4).<\/li>\n
  • \u00a0Two versions of UNIX that emerged are AT&T Unix and BSD Unix.<\/li>\n
  • \u00a0Two of the main standards mainly in use are POSIX (Portable Operating System Interface) by IEEE and X\/open standard. X\/Open Company, Ltd. was a consortium founded by several European<\/li>\n
  • UNIX systems manufacturers in 1984 to identify and promote open standards published its specifications under the name X\/open Portability guide( XPG4).<\/li>\n
  • \u00a0Single UNIX Specification (SUSv3) – incorporating IEEE Std 1003.1 and ISO\/IEC 9945 and integrating the industry’s Open Systems standards.<\/li>\n<\/ul>\n

    Why has Unix been successful?<\/h3>\n
      \n
    • Application portability and scalability.<\/li>\n
    • Open System.<\/li>\n
    • Underlying operating system source code is available.<\/li>\n
    • Provides a productive environment.<\/li>\n
    • Allows multi-tasking and sharing of data.<\/li>\n
    • Excellent C development environment is built-in.<\/li>\n
    • Networking capabilities are built in.<\/li>\n
    • Very important feature of UNIX is that the source code is open , which gives a larger scope for development and debugging.<\/li>\n
    • \u00a0One important advantage that results from the UNIX standard interface is application portability.<\/li>\n
    • Application portability is the ability of a single application to be executed on various types of computer hardware without being modified.<\/li>\n
    • This can be achieved if the application uses the UNIX interface to manage its hardware needs.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
