Typical computer system
Cpu, main memory,secondary storage devices ,input devices,output devices
Disk drive
Stores data by magnetically encoding it into a circular disk
Input devices
Keyboards, Moises, scanners, microphones, and digital cameras
Dvd-Roms, cd-Roms
Optical devices
Fetch
Reads instruction from memory
Source code
The statements the programmer writes in high-level languages
High-level language
Allows to create powerful and complex programs without knowing how the CPO works and without writing large numbers of low-level instructions
Byte
Memory to store one letter of the alphabet or a small number
Methods
OpeRations that an object can perform on
8 bits
Byte
Object oriented
You can create programs by putting together a collection of objects
Text box
Object appears as a rectangular region that can except keyboard input from the user
Fetch decode execute cycle
Went to CPU executes the instructions in a program it is engage in the process
Statement
Each instruction in a program is called this
Compilation
Translates a text based source code to binary codes
Cpu
Central processing unit is the part that actually runs programs
Hardware
Refers to all physical devices
Excecute
Actually performs the actions
Properties
The data stored in an object are commonly called fields or
Form actions
Object oriented programming a window that is displayed on the screen
Universal serial bus
Small devices that plug into computer's USB port and appear to the system as disk drives
Ide(Integregated development environment)
Provide all the necessary tools for creating testing & debugging software
0's and 1's
All data stored in a computer is converted to this sequence
Digital
Can only have two possible values
Binary digit
The term bit stands for
Programmers or software developers
Create software
Syntax error
A mistake or violation of these rules
Bit
Each sequence is called this
Operators
Keywords that represent special program functions such as addition subtraction and multiplication
Property windows
And visual see application you examine and change a control,text box or Picturebox in this
Event driven
Gui programs must respond to the actions that by the user
Decode
Decodes instructions that were just read to determine how to perform operations
Secondary storage devices
Devices that can hold data for long periods of time even when the power is off
Syntax
Set of strict rules that must be followed when writing program
Assembly languages
Uses short words known as mnemonics to write program
Project
Each visual C sharp application you create is called
Output devices
Video displays, speakers, printers
Application software
Programs that perform special tasks
Logic error
A mistake that does not prevent the program for running but does cause it to produce incorrect results
Compiler
A program to translate a high-level language program into a separate machine language program
Class
Code that describes a particular type of object don't do do you do with that
Controls
Objects that are visible in a program graphical user interface
System software
Programs that control and manage the basic operation of a computer
Toolbox
A window that allows you to select the controls that you want to use in applications user interface
Programs
A set of instructions that a computer follows to perform tasks
Label
Objects that display text on the form
Main memory
The computers work area commonly known as ram volatile type of memory
Machine language
Computers can only understand instructions that are written in
Digital data
Data stored in binary
Digital devices
Devices that work with binary data
