Terms in this set (78)
Hardware The physical components of a computer.
Software written programs or procedures or rules and associated documentation
pertaining to the operation of a computer system and that are stored in
read/write memory
main memory holds current memory, volatile (goes away)
auxiliary memory exists once the computer turns off (hard drive)
input keyboard, mouse, etc.
output monitor, printer, etc.
RAM Random Access Memory - is the main memory, and the hard drive is the principal
CPU (Central Processing Unit) The key component of a computer system, which
contains the circuitry necessary to interpret and execute program instructions
1 bit smallest unit
4 bits nibble
8 bits 1 byte
1,000 bytes 1 KB
1 million bytes (1,000 kilobytes) 1 MB
1 billion bytes (1,000 megabytes) 1 GB
bytes in larger units are ____ files
Files are organized into ____ folders or directories
machine language (what the computer understands)- is a "low-level language" which is binary
(01001101)
"high-level language" A programming language like Java that is designed to be easy for humans to read
and write.
JVM Java Virtual Machine, an interpreter for compiled Java bytecodes - translates and
runs the Java bytecode
, OOP Object-Oriented Programming- views a program as similarly consisting of objects
that can act alone or interact with one another
Encapsulation packages and hides details
Polymorphism allows the same program instruction to mean different things in different contexts
- one method name causes many different actions
Inheritance is the way of organizing classes
code HelloWorld public class HelloWorld{
public static void main(String[] args){
System.out.print("Hello World");
}
}
Variable(s) store data and/or values
data types say what the variable is storing
int whole numbers
double or float decimals
char characters (letters)
boolean true or false
string words/phrase
primitive types int, char, double/float
constants variables that next change in your code - written as:
final int thisNumber = 4;
or
int THIS_NUMBER = 4;
True or false: true
Java is case sensitive
"keywords" that should NEVER be included in your code if, public, class, while, for, print, etc.
order of data types by size: byte-short-int-long-float-double
e notation: 4x10^8 4e^8
"=" the assignment operator, gives a variable a value
