We encounter cycle stealing in the context of Direct Memory Access (DMA). Either the DMA controller can use the data bus when the CPU does not need it, or it may force the CPU to temporarily suspend operation. The latter technique is called cycle stealing. Note that cycle stealing can be done only at specific break points in an instruction cycle.

What is happening when a computer is turned on and the operating system is being loaded?
On a "traditional" PC, the sort most homes have, running Windows operating system, when you power up the machine it runs through a boot cycle. This includes: The BIOS (Basic input/output system) The BIOS' job is to check the hardware components of your machine, looking for harddrives, floppy drives, memory, keyboards, mice, processors etc... all the hardware components that make up a complete PC. It performs various checks, in many PCs this includes checking that the keyboard and mouse are attached. If they are not, the system grinds to a halt. After the bios has run, it checks your main hard drive for an operating system "bootloader". If it can't find one, it will either prompt you to insert a CD or will again come to a grinding halt. The Bootloader tells the machine what operating system you have installed, and where to look for it on your harddrive. Once it finds your operating system, it will load up "driver" files. Driver files make all your hardware work correctly. They are the bits of software that for example, tell your Monitor it should change resolution, or tell your modem to pick up the phone line and dial a number... With windows (and other operating systems) there are driver files that are quite critical, and need to be loaded before the system can start. If they are missing or damaged the system will stop responding. At best, it may prompt you to enter "safe mode" where you can attempt to repair or replace these files. Once all that is done, the main operating system loads the GUI. The Graphic User Interface - the screen and controls we are all used to. Then its simply a case of selecting your user account and logging on. On other computer equipment, these procedures may vary. But in general, thats how it happens.

What concept is used to address the interplay between system performance availability (reliability maintainability and supportability) process efficiency and system life cycle cost?
Affordable System Operational Effectiveness (ASOE)
How is multiprogramming achieved by an operating system?
When the timeslot for the current program runs out, the routine saves the current CPU context into a datastructure, selects a new program to be run for the next timeslot, and loads the CPU registers with the values that were saved in that process's datastructure. Hence a new program gets the CPU. This cycle continues till all programs are terminated or aborted.
What is a 16-bit operating system?
Basically, the difference lies in the way the program process information : 2 bytes at a time for 16 bits, 4 for 32 bits. Older system usually use a 16 bits processor (often with a 32 bits "virtual" capacity), while newer system all use 32 bits processors that can input 4 bytes of information per clock beat for processing. During a single cycle of the CPU processor, a 16-bit program can send 16 bits of instructions to the CPU. A 32-bit program can send twice as many (32 bits) of instructions during a single cycle. Therefore, 32-bit programs are often able to run faster than 16-bit programs but because the speed of a program is effected by so many other factors, a 32-bit program is unlikely to be twice as fast as a 16-bit program
What is cycle stealing technique?
Cycle stealing is a technique used in accessing a computer's RAM without having to pass through the CPU. It is similar to direct memory access or DMA.

What is the difference between mode and state?
States define an exact operating condition of a system, where modes define the set of capabilities or functions which are valid for the current operating condition. (Source: http://themanagersguide.blogspot.com.au/2011/01/6322-define-life-cycle-system-modes.html)

The cash cycle starts when you pay your supplier and ends when your buyer pays you. The operating cycle starts with acquiring of inventory or raw material ands ends with receipt of payments of your good.
