Basic Computer Concepts Flashcards
System
collection of components that work together toward a common goal which is to take in input and transform it into output
Information System
Interrelated components working together to collect process store and disseminate information for the coordination control analysis and visualization in an organization
Data processing
Collection and manipulation of data into useful information within a given context
Information Technology
Technology which supports activities involved with the collection storage and manipulation and communication of information together with their related methods, management and application
Hardware
Tangible parts of a computer
Software
Set of instructions that tells a computer what to do
Types of software
system eg Windows, Android
application eg Candy crush
Network
Connects computer systems and portable wearable devices to transmit info
Data
raw unprocessed facts including text numbers
images and sound
People
End users who use computers to make themselves productive
Procedures
Series of steps taken to achieve a desired outcome(not only automating organizational processes but also to improve them)
computer
Electronic device that receives input, processes it and produces an output based on the input given
components of a computer
processor, memory, Mechanism for transfer of data to and from the world
Information
Data that has been processed and given meaning within a certain context
CPU
electronic circuitry which executes instructions to process data
List parts of a computer system
Electronic components eg Motherboard, CPU,RAM etc
What are the uses of Information systems?
Supports decision making supports coordination supports control supports analysis supports visualization
What are the six stages of data processing?
collection, preparation, input, processing, output and storage
Discuss how IT is a subset of IS?
IT is the technology that supports IS. IS is an umbrella term for the systems people and processes designed to create, store, manipulate, distribute and disseminate information. Not all ISs are computer based.IT falls under IS but deals with the technology involved in the systems involved
What is digital data?
Data that represents other forms of data using specific machine language systems that can be interpreted by various tech.
What is the main difference between 5th generation computers and all other generations of computers
Increase in speed and capacity, Decrease in power consumption and heat generation and other features like voice recognition
Why is the CPU referred to as the brain of the computer?
I t is the main center of computer which controls the working of the computer
