CHAPTER ONE COMPUTER SYSTEM FUNDAMENTALS 1.1 Computer System as a Universal Tool A computer system is an electronic device that accepts inputs; transform the input through some processes to obtain output or information that can aid effective decision making. Information originated from raw data which by its own simple definition is any raw fact or figure that can be subjected to a form of manipulation before it can be trusted for decision making. Data can originate from various sources depending on the user or purpose of gathering and can be processed manually, mechanically, electromechanically or pure electronically e.g. statistical data gathered through surveying, personnel data, student data through filling of some forms. Data†¦show more content†¦The machines then were mainframe computers that work under pressure and generate a lot of heat. The operators run up and down to load batched punch cards that contain user defined source codes, mount the magnetic disks or tapes. Because the computer time was valuable, the early machines ran 24 hours a day an d operator works in shifts. Jobs were submitted in batches and operated upon at the same time. The user interface on early computers consisted of stacks of punch or hollerith cards invented by Hollerith, one of the early computer inventors and instructions are coded in a special languages and organized using early Job Control Languages.. Early computer programming calls for experts and the job owners are virtually alienated from the operation of the computers. 1.2.1 Time Sharing Era The invention of the minicomputers in 1970s witnessed a new dimension to computer users. Hundreds of users operate the computer simultaneously, each having a terminal (keyboard and monitor) to himself.Show MoreRelatedcomputer fundamental1111 Words   |  5 PagesSelected objective question on Introduction to Computers with answer :Set 4 1.

Large data collection and analysis emphasized a purportedly more systematic empirical approach to developing theory. Key words: accounting; neo-empiricism; capital markets research; behavioural

Learning Behavior Essays - 707 Words

Learning Behavior Psychologists have preformed many studies and proposed many theories regarding learning. Learning can be defined as a relatively permanent change in behavior that is due to past experience. John B. Watson was an early psychologist that didnt agree with many other psychologists ideas about learning only relating to consciousness and thought processes. As the founder of behaviorism, Watson studied learning in a behavioral perspective, an approach that emphasizes the relationship between outwardly observable behaviors and environmental events, rather than mental processes. Classical conditioning is a process of learning associations between stimuli used by Ivan Pavlov, a Russian physiologist. In†¦show more content†¦Skinner believed that classical conditioning was limited to behaviors that are reflexively elicited. An operant describes behaviors that are operate upon the environment to generate consequences. Reinforcement follows an operant and increases the likelihood of the operant being repeated. There are two forms of reinforcement: positive and negative reinforcement. When an event occurs producing a positive effect, it is considered positive reinforcement. Negative reinforcement involves the removal of a stimulus increasing the likelihood of a positive effect. An example of this would be to take two aspirins to remove the pain from a headache. Punishment is a process that decreases the likelihood of a behavior to occur again. This is not to be confused with negative reinforcement because it doesnt increase the likelihood of an occurrence. There are drawbacks to punishment. It doesnt teach an appropriate behavior to replace an inappropriate one. Also, intense punishment can lead to results such as passivity, fear, anxiety, or hostility. Finally, effects of punishment are sometimes temporary. An alternative to punishment is trying to change the behavior of others. First, stop reinforcing the problem behavior by identifying the reinforcer and elim inating it. When it is not possible to eliminate the reinforcement, remove the opportunity to obtain positive reinforcement. An example of this would be time-out for a child because he or she is no longerShow MoreRelatedLearning Behaviors And Their Own Way Of Learning Specific Behaviors1251 Words   |  6 PagesEvery individual has their own way of learning specific behaviors.
