CMPT 128Introduction to Computing

Science for Engineering Students Computer Components


Hardware and Software A computer is a machine designed to perform

operations specified with a set of instructions called a program.

Hardware refers to the computer equipment. Peripheral Input devices: keyboard, mouse, Peripheral Output devices: screen, disk, DVD, printer Processing/storage devices: cpu, RAM, ROM, DVD

Software refers to the programs that describe the steps we want the computer to perform.


CPU

Computer Hardware CPU –

Central processing unit ALU –

Arithmetic and logic unit ROM –

Read only memory RAM –

Random access memory

InternalMemory

ExternalMemory

InputDevices

?

OutputDevices

?

Processor

ALU

Cache/Memory


Central Processing Unit (CPU, ALU) Performs arithmetic

The processor adds, subtracts, multiplies and divides binary numbers using the Arithmetic Logic Unit, ALU

Makes comparisons The processor can check if two “numbers” are equal,

and determine if one is “larger” or “smaller” than the other

Moves bits (binary digits) Knows how to access any RAM (or ROM) address Can copy data to or from any memory address and

its own onboard memory

Information storage Primary Storage: RAM, ROM

requires power to store information Secondary Storage: Disk, DVD, thumb

drives, SD cards … Less expensive (so more plentiful) Information persists even without power Stores information that is loaded into primary

storage (like programs and data) to be used



Example: Command Line UI Windows Command Prompt


Example: Graphical UI (GUI) Windows explorer


Computer Software: Applications

Application Software (Software Tools) Word processors (Microsoft Word, WordPerfect, ...) Spreadsheet programs (Excel, Lotus1-2-3, ...) Computer games Communication software (email, chat, web

browser…) Telecommunication software (VOIP, …) Programming environments (Visual Studio, Eclipse) OTHERS?


Computer Software: Languages Some Computer Languages

Machine language (machine instruction set) assembly language high level languages

C, C++, Ada, Fortran, Basic, Java Do YOU know of any others? mathematical computation and symbolic manipulation tools

(MATLAB, Mathematica, ...) Application software is written using computer

languages.


Machine language Each type of processor (like i7, Pentium 4,

Athalon, Z80, …) has its own instruction set Each instruction in an instruction set does a

single thing like access a piece of data, add two pieces of data, compare two pieces of data …

Each instruction is represented by a unique number This # may be different for different instruction sets, but no two instructions in the same instruction set will have the same #


Machine Language programs In machine language a program is a list of

instructions Each instruction is represented by a number Inside the memory of the computer each

number is represented in binary (as a constant length string of 1’s and 0’s)

The long string of 0’s and 1’s is easy for the computer to understand and very difficult for a Human to read or write


Assembler Assembler languages make it easier for

the programmer. Assembler is easier for humans to read/write The numbers that identify each of the

instructions in the instruction set are replaced with mnemonics like ADD, CMP, …

The code, written using these mnemonics is written into a text file.


Assembler Programs The code for an Assembler program is written

into a text file. The computer read 1’s and 0’s not text How do we translate to machine readable form?

A computer program called a compiler is used to translate the text file (called a source file) containing the assembler code into machine readable code

The compiler writes a binary file containing the machine readable code (called an object file)


Programs in High Level Languages Assembler is easier to read/write than machine

language. It is still very cumbersome High level languages are easier to write than

assembler The compiler is more complex, but that is a tool you

use, not one you write In this course we will learn the language C++ Many ideas we will discuss in this course are

equally applicable to C++ or to any other compiled high level language (C, Fortran, …)
