Convectional computing is a type of computing which operates within the framework that were programmed into it.It contains processor speed and memory,but the code it have which softwaredesigners and writers have produced.An Intelligence is much like humans, make choice as it’s own. It would be able to learn and in essence, invariably reprogram itself. It would be able to make decisions based on a moreproper or novel,but not programmed in accurate manner.Convectional computing is rule based computing. Rules are clearly defined and implemented in the programming language so that computing function can behave in certain condition.An Intilligent computing are observation and learning based sysytems.They observe the surroundings and theenvironment, the past data and how the system has responded in past to certain data.Based on this data, a pattern is esablished and automatically the system follow these rules. An Intilligent is based on hard computing techniques using a modern chipset.Convectional computing uses a combination of techniques both hard and soft including fuzzy logic. It can be said that convectionalcomputing subsumes artifical intilligent.Convectional Computing functions logically with a set of rules and calculations.It is often unable to manage the variability of dataobtainen in a real world.An Intilligent can function via images,pictures and concepts.It is like our brains is well suited to suitations that have no clear algorithmicsolutions and are able to manage noisy imprecise data.This allows them to excel in those areas that convectional computing often finds difficult.Convectional computing is a computing which guarantees a solution to a given problem.Intilligent computing is a computing which doesn’t guarantee solution to given problem.Convectional computing is based on algorithms whose instructions are stored in memory and executed are stored in memory and executed in sequential way.An Intilligent computing are not based on algoritms but it uses resoning and inferencing over the knowledge base to search and pattern matching.AnIntilligent computing can solve a range of problems in a given domain.Convectional computing can solve only one problem at a time in a given domain.In Intilligent computing programmers design artifical intilligence software to give the problems to computer not the steps to solve it.In Convectional computing programmers originally design software that accomplished tasks by completing algorithms.
