38. Labs and using CSIL Computers in CSIL are available 24/7
Labs for many classes are scheduled in CSIL
When a lab (not your own) is scheduled in one of the CSIL areas you are requested to work in another area of CSIL. The schedule showing which areas are in use can be found at
© Janice Regan, CMPT 128, Sept

39. Required Lab Hours Attendance at Lab hours is required
Lab Hours are held in the Windows area of CSIL labs
Lab Hours provide an opportunity to work with others sharing knowledge and experience.
Lab Hours give you an opportunity to ask the instructor or TA one on one questions about problems and assignments.
Lab Hours help you learn the required concepts one by one and allow you to ask questions to assure you understand each one.

41. CMPT 128 Introduction to Computing Science for Engineering Students
Computer Components

42. 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.
© Janice Regan, CMPT 128, Sept

43. Computer Hardware CPU – ALU – ROM – RAM – Central processing unit
Arithmetic and logic unit
ROM –
Read only memory
RAM –
Random access memory
Internal

Devices ?
ALU
Cache/
Memory
© Janice Regan, CMPT 128, Sept

44. 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
© Janice Regan, CMPT 128, Sept

45. 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
© Janice Regan, CMPT 128, Sept

46. Example: Command Line UI
Windows Command Prompt
© Janice Regan, CMPT 128, Sept

47. Example: Graphical UI (GUI)
Windows explorer
© Janice Regan, CMPT 128, Sept

48. Computer Software: Applications
Application Software (Software Tools)
Word processors (Microsoft Word, WordPerfect, ...)
Spreadsheet programs (Excel, Lotus1-2-3, ...)
Computer games
Communication software ( , chat, web browser…)
Telecommunication software (VOIP, …)
Programming environments (Visual Studio, Eclipse)
OTHERS?
© Janice Regan, CMPT 128, Sept

49. 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.
© Janice Regan, CMPT 128, Sept

50. 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 #
© Janice Regan, CMPT 128, Sept

51. 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
© Janice Regan, CMPT 128, Sept

52. 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.
© Janice Regan, CMPT 128, Sept

53. 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)
© Janice Regan, CMPT 128, Sept

54. 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, …)
