ICT 1st Prelim Flashcards
ICT
Information Communication Technology
It is a diverse set of technological tools and resources used to transmit, store, create, share or exchange information
ICT
A set of instructions, data or programs used to operate computers and execute specific tasks
Computer software
The programs that are needed to accomplish the input, processing, output, storage, and control activities of information systems
Computer hardware
Installed inside the computer
Internal components
Connected to the outside of the computer, these can also be referred to as peripherals, or peripheral devices
External components
A collection of programs designed to operate, control, and extend the processing capabilities of the computer itself
System software
These are designed to satisfy a particular need of a particular environment
Application software
The process that professionals use to write code that instructs how a computer, application or software program performs
Computer programming
The first computer programming language was created in
1883
The woman worked with Charles Babbage on his very early mechanical computer, the Analytical Engine
Ada Lovelace
Use classes and functions that control commands
Programming languages
Getting data and commands into the computer
Input
Getting your results out of the computer
Output
Testing to see if a condition is true of false, and cycling through a set of instructions until some condition is met
Looping and conditionals
Performing mathematical calculations on your data
Mathematical operations (arithmetic)
Storing information, which may change over time
Variables and data structures
The element of computer programming allow interaction of the program with the external entities
Input or Output
A sequence of instructions that are repeated continuously till a certain condition is not satisfied
Loop
The execution of the statements depending on the whether condition is satisfied or not
Conditionals
Tells how the data is represented which can be range from very simple value to complex one
Variables
The element of the programming allow a programmer to use snippet of code into one location which can be used over and over again
Mathematical operations or Subroutines and functions
