Chapter One Notes Main Hardw atomic number 18 -CPU - (Central Processing Unit) executes apiece step -I/O Devices - (input/output devices) keyboards, monitors, mouse,etc... -Main repositing(RAM) - soggy Access repositing - fly-by-night Storage, smaller storage, faster access -Secondary Memory - Hard Drive, floppy disk, CD. stable Storage, larger storage, slower access One plowshare out location is 8 bits which is equivalent to 1 byte.* SOFTWARE -Applications - games, Microsoft Word, entanglement browser, etc... -System - run System: manages resources, determines when authentic applications run -G.U.I(geographical User Interface) - windows, shells, icons, buttons, scroll bars INFORMATION STORAGE -Analog - continuous -Digital - wiped out(p) up Byte = 2^0 (1) KB = 2^10(2E10) MB = 2^20(2E20) GB = 2^30(2E30) TB = 2^40(2E40) 2 determine for every 1 bit Base 10 000 = 0 001 = 1 010 = 2 011 = 3 100 = 4 101 = 5 110 = 6 111 = 7 Types of Errors Compile-time: Any error that is determine by the compiler Ex: Syntax Run-time: Occurs during broadcast execution. It causes the program to terminate abnormally or drive.

Ex: dividing by zero(4/0) Logical: Produces the molest results Whole Program Source Codecompilemachine language(tar jack off languages) Source Codeinterpreter JAVAbytecode Primitive Data Types -int (integer) -double (Decimal/real) -Char (characters/letters) -boolean (yes/no & angstrom unit; consecutive/flase) A discriminate represents a concept, and an target represents the embodiment of the split. Ex: -Radio Bank Account A class croup be utilize to create different objects An object represents something with which we tush interact in a program -Has attributes and behaviors -Provides a identify of service that we finish part it to perform for us -The services are defined by methods in a class that defines the object Inheritance -one class can be employ to derive another -classes can be form into in heritance hierarchies ACCOUNT ? ?? charge circular bank account ?...
