- 3. Unix is one of the very oldest operating systems in the computer world, and is still widely used today. However, it is not a very conspicuous operating system,unix operating systems are designed to use the unix file system. Unix:-
- 4. In the 1960s, the massachusetts institute of technology, AT&T bell labs, and general & electric worked on an experimental operating system called multics (multiplexed information computing service), which was designed to run on the GE-645 mainframe computer. The aim was the creation of a commercial product, although this was never a great success. History Of Unix:-
- 5. Shell functions:- functions enable you to break down the overall functionality of a script into smaller, logical subsections, which can then be called upon to perform their individual task when it is needed. Using functions to perform repetitive tasks is an excellent way to create code reuse. Unix Functions:-
- 6. Different flavors of Unix have different cost structures according to vendors Divided into various other flavors, mostly developed by AT&T Three bigest distributions are Solaris (Oracle), AIX (IBM) & HP-UX developed mainly for mainframes, servers etc. Unix Functions:-
- 7. The history of linux began in 1991 with the commencement of a personal project by finnish student linus torvalds to create a new free operating system kernel. Since then, the resulting linux kernel has been marked by constant growth throughout its history. Linux:-
- 8. FUNCTIONS OF LINUX:- Linux can be freely distributed, downloaded freely Linux is developed by Open Source development Linux kernel is developed by the community. Linus Torvalds oversees things. User Everyone.
- 9. Virtual memory is a feature of an operating system (OS) that allows a computer to compensate for shortages of physical memoryby temporarily transferring pages of data from random access memory (RAM) to disk storage. Virtual Memory:-
- 10. A microkernel (also known as μ-kernel) is the near-minimum amount of software that can provide the mechanisms needed to implement anoperating system (OS). These mechanisms include low-level address space management, thread management, and inter- process communication (IPC). MicroKernels:-
