On line Real Time Processing
On Line Processing: In on line processing the transaction data is directly sent to secondary on-line storage devices by the CPU without sorting, from the point where data is generated.…
Time Sharing
In time sharing, it is possible for multiple users to run more than one application at the same time on the computer. This is accomplished by providing a=separate terminal to…
Multiprocessing
In multiprocessing systems, two or more CPUs are connected together. Therefore it is possible to execute instructions from different programs at the same time. Thus more than one instruction can…
Multiprogramming
In multiprogramming the CPU is capable of running more than one program concurrently. More than one programs can reside in the main memory at any given time, however the processor…
Testing, Documentation Maintenance
Testing (Validation): The program is tested on a number of suitable test cases. A test plan of the program has to be done at the stage of the program design…
Debugging
At this stage the errors in the programs are detected and corrected. This stage of program development is an important process. Debugging is also known as program validation. Some common…
Coding
Once the design process is complete, the actual computer program is written, i.e. the instructions are written in a computer language. Coding is generally a very small part of the…
Modular Programming
Using this method the entire program is divided into smaller manageable modules so that the smaller modules can be designed, coded and debugged separately. Top-Down Design: Here the overall problem…
Types of logic used in the flowchart
Sequential Execution: In this logic the instructions are executed one after the other sequentially. Transfer of control: This is a logic which is used when the option to be chosen depends…
Program Development Process
While writing a computer program, it is absolutely necessary to write .each and every instruction in the correct sequence. The logical control of element within the computer program is the…
