Computer applications

Data Processing

               Computer data processing is any process that a computer program does to enter data and summarize, analyses or otherwise convert data into usable information

Using Computers for Information Processing:

• Tasks can be completed faster because computers work at amazing speed.
• Computers can process large amounts of data and generate error-free results, provided that the data is entered correctly.

Uses of Computers in Education

Higher Education

·         All universities and colleges in the United States are furnished with computer labs. Because many professors require their students to turn in typed documents, it is more convenient to have computer labs on campus for student use.

Online Education

·         There is an entire "sub-industry" of education called "online education." Online education is done primarily through the usage of computers and the Internet where the student does the classwork from home.

Faculty Usage
