Computer:- "Computer is an electronic device used for performing various task as taking the data from input device , process it and give the result to output device."
Components Used In Computer:- There are 3 main components used in computer system given below:-
1-Input Devices:- In computer input devices are used for taking data. e.g - Keyboard.
2-Output Devices:- In computer output devices are used for showing the result. e.g- Display screen.
3-CPU:- CPU is called the brain of the computer. It process all the data and give the result.e.g- ALU(Airthematical logical unit).
Technology:- "The term technology means modification, usage and knowledge of tools machines, methods and system in order to solve a problem."
Technology basically refers to solve the technical problem. Now a days various technologies are used for giving knowledge about various purpose like Medical Technology, Bio Technology, Nanotechnology Technology, Computer Technology and many more.
So what is computer technology?
The first electronic digital computers were developed in the mid-20th century . Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). In this era mechanical analog computers were used for military applications.
Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small enough to fit into mobile devices, and mobile computers can be powered by small batteries.
Personal computers in their various forms are icons of the Information Age and are what most people think of as “computers”. However, the embedded computers found in many devices from mp3 players and iPods to fighter aircraft and from toys to industrial robots are the most numerous.
So computer technology basically refers to the usage and knowledge of tools, techniques,methods of organization in order to solve problem of computer.
