what are similarities and differences between linux and unix?
Because Linux evolved from UNIX, but Windows evolved from DOS.
There are Windows Server, Linux, BSD, and even Apple's own server
There is very little difference in the C compiler between Unix and Linux; in some cases (the gcc compiler) it is the same. The differences come in when using system calls; some system calls do not exist in Unix or Linux, although most do. The program I work on compiles the same way (for the most part) between all commercial versions of Unix and several variants of Linux. In other words, the code is fairly portable across platforms.
Since there isn't a UNIX 95 or UNIX 98 per se, I think you are referring to Windows 95 or Windows 98..
Windows, Linux, Ubuntu, Linux Mint, the list is huge!
Linux is a Unix-like system. This means that it is inspired or influenced by Unix in some shape or form (Linux started off from Minix), but it is not directly derived from Unix. However, BSD is based on Unix, and macOS is indirectly Unix-based because of its mixed heritage with BSD.
Windows, Linux and UNIX machines
Windows, Linux, Unix.
unix is a multiuser operating system but widows is a single user operating system.
Unix and windows are two separate groups of operating systems. Windows is the operating system of about 90% of personal computers, while unix is the basis of many other operating systems, such as Mac OS X
Unix, Linux, windows and compilers etc.
