Part I:Let’s Begin!

Basic Computer Components Peripherals Central Processing Unit ( CPU ) (where work is done) Input Device Control Unit Arithmetic Logic Unit Output Device Auxiliary Storage Device(s) Memory Unit ( RAM) (program code will be placed here)

Memory Main Memory/RAM Numbered locations or addresses Computer places instructions or data during operation

Central Processing Unit (RAM) UNICODE Extends ASCII Latin-I is International

Central Processing Unit (RAM) Byte = a memory location memory => 8 ASCII Character The number on the keyboard you type. Binary is stored in => 8 Central Processing Unit (RAM) What will be the ASCII, binary Representation for the number 8?

Central Processing Unit (RAM) Byte = a memory location memory => A ASCII Character The number on the keyboard you type. Binary is stored in 1 1 65 A => A Central Processing Unit (RAM) What will be the ASCII, binary Representation for the number 8?

Software Operating System Program

JAVA Programs Translates source code (statements you write) Produces bytecode or .class file Source File .java Bytecode .class Editor compiler interpreter Library files
