Final answer:
The other Unix operating system type besides BSD is System V, under which IBM's AIX, HP's HPUX, and Oracle's Solaris fall. Linux emerged as an open-source alternative to expensive UNIX systems, leading to the displacement of proprietary systems in many markets.
Step-by-step explanation:
The other type of Unix operating systems, apart from BSD, is called System V. IBM's AIX, HP's HPUX, and Oracle's Solaris are examples of Unix operating systems that belong to the System V lineage. These proprietary distributions, which originate from UNIX developed by AT&T Bell Labs and commercialized later through various entities like Novell and the Santa Cruz Operation (SCO), offer similar functionality but are specifically tailored to run on the hardware of the companies that developed them, often with a significant cost associated.
On the other hand, the Linux operating system, created by Linus Torvalds as an affordable and configurable alternative to UNIX, has seen widespread adoption in a variety of applications, from personal computers to network servers and supercomputers. As a result of the flexibility and cost-effectiveness of Linux, many proprietary systems like IRIX and Sun Microsystems' workstations found their markets shrinking rapidly.
