Computer software can be defined as the intangible component of the computer system. The operating system is an interface between the computer hardware and computer users. Every computer system, no matter the size, requires an operating system to function effectively.
In the world today, the computer system has proven to be invaluable to mankind. In this tutorial, we discussed the concept of the computer system for beginners and junior secondary school students.
Classification by degree of versatility is also called classification of computers by purpose. It is a grouping of computer systems based on what they can do.
Classification of computer by type distinguishes computers based on the form of data it processes. The precision of a computer system can be described in two ways: discrete, and continuous.
We can also classify a computer system by size. Classification of computers by size is important to computer scientists and users.
It allows us to group the computer system based on the physical magnitude and processing power.
Classification of computers by generation is a process of arranging computers based on the period of invention. When classifying a computer system, certain characteristics are considered.
The features of graphic packages are tools within the software environment that make creating and editing graphics possible. Most of the graphic packages discussed under examples of graphic packages have brushes, pens, etc to create and edit objects.
Examples of graphic packages used by graphic designers abound. There are different categories ranging from raster to vector application software. These are graphic packages you can use to manipulate images and scanned documents.
The types of graphic packages discussed in this tutorial are those approved for junior secondary/high schools. A computer graphic application package is software used to create and edit shapes and images.
what is graphic packages? Graphic packages are mobile and desktop apps used to create and modify images.
Electronic counting devices are improved mechanical devices that use electricity circuitry to function effectively. You will learn the following: Hollerith punch cards, Neumann machines, modern computers, list of electronic counting devices...
An electromechanical counting device is defined as a calculating device that combines manual and electrical processes. Examples include Pascaline, Leibniz calculator, Jacquard loom, and Analytical engine.
Mechanical counting devices are manually operated devices for counting and calculating numbers. They are simple equipment that can be operated manually by individuals.
Early counting devices are simple counting and calculating objects used to perform basic additions and subtractions. Before modern civilization, people invented counting devices that helped them perform simple calculations.
