POS420: DQ's to get Week you
Discussion Question 1 -- Week one particular (Saturday):
Just how old of the operating system is usually Unix?
The story of how UNIX had become is a very long, but interesting tale. During the mid-1960's, the first multi-user operating system referred to as Compatible Time-Sharing System (CTSS) was created by simply Fernando Corbato at the UBER Computation Middle. Although CTSS was highly influential due to the time, that eventually failed, but not just before a second generation operating system referred to as Multiplexed Data and Processing System (MULTICS) was developed. MULTICS was began as a joint research project with AT& Big t Bell Laboratories, General Electric power, and UBER, but because of the high routine service costs associated with that, AT& Capital t Bell Laboratories pulled out. Two of the individuals working on the MULTICS project, Ken Thompson and Dennis Ritchie, wrote a computer game (Space Travel) on the MULTICS system and were able to transfer it into a PDP-7 laptop. By 69, the file-system and some basic utilities was created and because the operating-system could simply support a single user, the name Uniplexed Information and computing System (UNICS) was handed to it as a scam for the MULTICS program. When multiprocessing functionality was added a short time later in the 1970s, the UNICS name was changed to UNIX. So , to answer the question, UNIX is over 40 years old.
Discussion Question 2 - Week 1 (Saturday):
Who owns UNIX?
As stated in my initial Discussion Question, UNIX was originally developed by Ken Thompson and Dennis Ritchie at AT& T Bells Laboratories in 1969. Today, the actual determination of who owns UNIX is unknown as a result of legal issues. Novell holds the patent legal rights, which they bought from AT& T in 1993; the Open Group holds the trademark as well as the Single UNIX Specification, and the copyrights happen to be owned by SCO Group (formally called Caldera Systems and Caldera International; at this point the Santa claus Cruz Operation), even though nothing has been recorded with...
