Study Notes
The Impact of Digital Computer Technology
- Digital computer technology has revolutionized the information age and influenced almost every aspect of daily life.
- Computers play a critical role in various applications such as:
- Flying modern aircraft and spacecraft
- Managing large databases (e.g., airline reservations and bank accounts)
- Telecommunications applications (e.g., routing and controlling telephone calls)
- Controlling power stations and hazardous chemical plants
- Supporting sophisticated medical procedures
What is a Computer?
- A computer is a programmable symbol-processing machine that accepts input symbols, processes them according to a sequence of instructions, and produces output symbols.
- Input and output symbols can represent various types of data, including:
- Numbers
- Characters
- Pictures
- Sound
- Other forms of data (e.g., chess pieces)
Programmability and General-Purpose Nature
- The most striking property of a computer is its programmability, making it a general-purpose machine.
- The user can change the program or input data to suit specific requirements.
- Depending on the software run, the end user "sees" a different machine, and the computer's behavior changes accordingly.
- A computer can perform various information-processing tasks by executing different programs, such as:
- Word processing
- Calculations
- Video games
- Multitasking (simultaneously performing different tasks)
- The computer's ability to perform a wide variety of tasks at high speeds and with high accuracy is what makes it so ubiquitous.
