Comparison Of Freebsd And Openbsd
What are BSD systems? These are systems based on the code the development of which was coordinated by Computer Science Research Group (CSRG) at Berkeley University. Some very long time ago, AT&T (1960-1970) had started developing an operating system we today know as Unix. However, at that time the above company [...]

Alternative Operating Systems
Alternative Operating Systems
Linux can be seen as the perfect alternative operating system. The Unix operating system was conceived and implemented in 1969 at AT&T’s Bell Laboratories in the United States by Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. Unix derived its name as a joke and reference to an experimental operating system that [...]
Data loss in HP-UX Computer
Data loss in HP-UX Computer
Few striking features that differentiate HP-UX (Hewlett Packard UNIX) operating system from other UNIX are enhanced reliability, security, workload management, and partitioning. This was the first UNIX operating system that used access control lists for file access permissions. Catastrophic data loss situations in HP-UX based hard drive or server can occur [...]

What is a BSD Unix?
BSD family of Unix systems is based upon the source code of real Unix developed in Bell Labs, which was later purchased by the University of California – “Berkeley Software Distribution”. The contemporary BSD systems stand on the source code that was released in the beginning of 1990’s (Net/2 [...]
