OBJECTIVE
This blog was created as a task assigned by the teacher to student ict.Besides that, I would like to share with other students in other related subjects ict.I hope with the blog, we will be able to increase knowledge of ICT subjects.
COMPUTER SYSTEM
A computer system is defined as combination of components designed to process data and store files.A computer systems consists of four major hardware components.For example input devices,output devices,processor and storage devices.A computer system requires hardware,software and a user to fully function.
INPUT AND INPUT DEVICES
Input is any data or instruction that you enter into the memory of a computer.There are four types of input which are text,graphic,audio and computer.
Input devices are any electronic device connected to a computer and produces input signals.
A mouse is also an input devices but it is called a pointing devices used to input data that is continuous and multi-dimensional into a computer.
A scanner is an example of input device for graphical as well as text input.
A keyboard is an example of input devices for text input.
PROCESS AND PROCESSOR
PROCESS = In computing, a process is an instance of a computer program that is being executed. It contains the program code and its current activity. Depending on the operating system (OS), a process may be made up of multiple threads of execution that execute instructions concurrently.
PROCESSOR = The processor (CPU, for Central Processing Unit) is the computer’s brain. It allows the processing of numeric data, meaning information entered in binary form, and the execution of instructions stored in memory.
example of processors :
STORAGE AND STORAGE DEVICES
STORAGE is a located which data,instruction and information are held for future use.Every computer uses storage to hold system software and application software.
STORAGE DEVICES is a device for recording (storing) information (data). recording can be done using
virtually any form of energy, spanning from manual muscle power in handwriting, to acoustic vibrations in
phonographic recording, to electromagnetic energy modulating magnetic tape and optical discs.
example far storage:
OUTPUT AND OUTPUT DEVICES
Output is data that has been processed into a useful form,called information.There are four types of output which are texts,graphics,audio and video.
Output device is any piece of computer hardware equipment used to communicate the results of data
processing carried out by an information processing system (such as a computer) to the outside world.
example for output devices:
CONCLUSION
In conclusion, I can share with other students about subjects ict.When I made this blog, I have enhanced the way the use of the internet properly.I hope, if things go wrong in my writing this, teachers and friends to help me to correct my mistakes.
