Soft real-time scheduling means that, while processor and other scheduling algorithms may be optimized to give preference to higher-priority processes, no absolute guarantee of performance can be made. The hard real-time computer is designed for specialized purposes, where even the smallest amount of latency can make the difference between life and death.
The answer to this riddle is a piece of gum.
uniprocessor : - A type of architecture that is based on a single computing unit. All operations ( additions, multiplications, etc ) are done sequentally on the unit. . multiprocessor : - A type of architecture that is based on multiple computing units. Some of the operations ( not all, mind you ) are done in parallel and the results are joined afterwards.

why we use disk scheduling in c ?
hard real time systems are systems that cant tolerate any delay or if delay happens the whole system will be worthless soft real time systems are systems that can tolerate delay In Vechile we are using Hard RTOS. Soft RTOS using in Live telecasting, Flight updation...
Yes, it is one of many scheduling algorithms suitable for time sharing.However it is not suitable for scheduling in a hard realtime OS that must consistently meet deadlines.
A complete answer to this question is beyond the scope of this website, as it requires several years of college courses and about twice that in on the job experience to properly learn. However it is basically an extension of standard systems analysis and design (which is still at least 2 full college courses) with a large amount of tedious bookkeeping added to make certain that all realtime requirements are fully met.Another point that is vital to understand is whether this is a hard realtime system or a soft realtime system. Hard realtime systems are much more difficult, as failure to meet even one of the real time requirements means total failure of the system to fulfill its purpose, making it useless. Soft realtime systems on the other hand are permitted to occasionally miss deadlines or otherwise fail to consistently meet some of the realtime requirements, as long as it is able to catchup later and meet the realtime requirements on the average.

Soft information refers to qualitative data that is subjective and difficult to quantify, such as customer satisfaction or market trends. Hard information, on the other hand, refers to quantitative data that is objective and can be easily measured, like financial statements or production numbers. Soft information is typically more open to interpretation compared to hard information.
