Introduction to Algorithms and Algorithmic Notation With Examples

Topic: Introduction to Algorithm and Algorithmic Notation With Examples What is an Algorithm? The step by step procedure to solve a particular problem is called an Algorithm . A Good Programmer always writes algorithms before developing programs. Algorithmic Notation with example algorithms Advantages of writing an Algorithm The process of solving a problem becomes simpler and easier with the help of algorithm. There are less chance of errors in the program, if we design algorithms before writing our programs in any programming language. We can convert an algorithm into a program of any programming language. It is not dependent on any programming language. Therefore it is easy to understand for anyone even without programming knowledge. What is the Relationship between an Algorithm and a Program Sponsored Links An algorithm is the sequenc of steps to perform a task, whereas a program is the set of statements to perfor...

What are Dual Devices or Both Input/ Output Devices

The devices that can be used to perform both functions -input and output- are called Dual Devices. These devices are also called Dual Purpose Devices or Both Input/Output Devices. With the help of a dual purpose device, we can enter data into computer as well as we can output data from the computer to outside world. For example, Dual devices include: Touch Screen Monitor, Modem, Network Interface Card, Sound card, Hard disk drive, Floppy disk Drive, Magnetic Tape Drive CD-Writer and DVD-Writer etc. These are also called Input/output devices, because they perform both functions. Touch Screen Monitor Dual Devices or Both Input / Output Devices - Touch screens Touch Screen Monitor is an input/output device. It uses a special touch sensitive screen. The User can enter data by touching icons or menus on the screen. As soon as the user selects a command from menu, output is displayed on screen. Commonly touch screen monitors use sensors to detect touch of finger. ...
