                 CS101 Short Notes – Lecture 1 to 22
Charles Babbage (1791-1871)
             Creator of the Analytical Engine - the first general-purpose digital computer (1833)

The Analytical Engine
             A programmable, mechanical, digital machine
             Could carryout any calculation
             Could make decisions based upon the results of the previous calculation
             Components: input; memory; processor; output

Ada, Countess of Lovelace (1815-52)
             Babbage: the father of computing
               Ada: the mother?
             Wrote a program for computing the Bernoulli’s sequence on the Analytical Engine -
              world’s 1st computer program
              Ada: A programming language specifically designed by the US Dept of Defense for
              developing military applications was named Ada to honor her contributions towards
              computing

A lesson that we all can learn from Babbage’s Life

              Charles Babbage had huge difficulties raising money to fund his research
               As a last resort, he designed a clever mathematical scheme along with Ada, the
              Countess of Lovelace
             It was designed to increase their odds while gambling. They bet money on horse
              races to raise enough money to support their research experiments
             Guess what happened at the end? The lost every penny that they had.

                   1. Fast
                   2. Bored
                   3. Storage

   Here is a fact:
 In 1997 Deep Blue, a supercomputer designed by IBM, beat Gary Kasparov, the World Chess
Champion
That computer was exceptionally fast, did not get tired or bored. It just kept on analyzing the
situation and kept on searching until it found the perfect move from its list of possible moves …

What is World Wide Web?

        A huge resource of information
        Logically unified: Any one from any where can access the information using a very
         simple scheme consisting of links & URLs
        Physically distributed: The information is stored on Internet-connected computers that
         are spread all over the globe

Browser
         A browser is an application program that provides a way to look at and interact with all
         the information on the World Wide Web.




URL

         YU-AHR-EHL or, in some quarters, UHRL - is the address of a file (resource) accessible
         on the Internet.
How many Web pages are there?

        In 1999 there were 800 million Web pages (15 terra (1012) bytes of text)
        In year 2002, the number is supposed to be 8 billion
        If you spend a minute reviewing each of these pages, it will take more than 15,000 years
         to go through them all

What is secret behind the explosive growth of the Web?

        Anarchy – any page is allowed to link to any other
        There are no controls over who puts what on the Web

  Everyone can put whatever they want to put on the Web – and they do!

Microprocessor
A microprocessor (abbreviated as µP or uP) is a computer processor on a microchip. It's
sometimes called a logic chip. A microprocessor is designed to perform arithmetic and logic
operations that make use of small number-holding areas called registers.
Integrated circuit
        Commonly known as an IC or a chip
        A tiny piece of Silicon that has several electronic parts on it

Components of integrated are

        Devices
        Transistors
        Diodes
        Resistors
        Capacitors
        Wires


And are made of the following materials


        Silicon - semiconductor
        Copper - conductor
        Silicon Dioxide - insulator

A Microprocessor System
        Microprocessors are powerful pieces of hardware, but not much useful on their own
        A microcomputer is 1 example of a microprocessor system
Micro Controller

        Micro-controllers are another type of microprocessor systems
        They are generally not that powerful, cost a few dollars a piece, and are found embedded
         in video games, VCRs, microwave ovens, printers, autos, etc.

        Modern super-fast microprocessors can process a huge amount of data in a short
         duration
        They require quick access to data to maximize their performance

On-Chip Cache Memory
    That small amount of memory located on the same chip as the microprocessor is called On-
    Chip Cache Memory
Bus Interface Unit
The bus interface unit is the part of the processor that interfaces with the rest of the PC.
Instruction Decoder
The instruction decoder of a processor is a combinatorial circuit sometimes in the form of a read-
only memory,
 A decoder is a device which is the reverse, undoing the encoding so that the original information
can be retrieved.

Microprocessor Building Blocks
Arithmetic & Logic Unit (ALU)
An arithmetic and logical unit (ALU) also known as “Integer Unit” is one of the core components
of all central processing units.


Floating-Point Unit (FPU)
A floating point unit (FPU) is a part of a CPU specially designed to carry out operations on floating
point numbers.

Registers
A register is a device for storing data. It is a small amount of very fast computer memory used to
speed the execution of computer programs by providing quick access to commonly used values.
Data registers are used to store integer numbers.
Address registers hold memory addresses and are used to access memory.
General Purpose registers can store both data and addresses.
Floating Point registers are used to store floating point numbers.
Constant registers hold read-only values (e.g zero or one).
Vector registers hold data for Single Instruction Multiple Data (SIMD) instructions.
Special Purpose registers which store internal CPU data like the stack pointer or processor
status words.

Control Unit
A control unit is the part of a CPU or other device that directs its operation. The outputs of the unit
control the activity of the rest of the device. A control unit can be thought of as a finite state
machine. It is called the brain of computer microprcessor.

Instruction Set
    The set of machine instructions that a microprocessor recognizes and can execute – the only
    language microprocessor knows

        2250 transistors
        108 kHz, 60,000 ops/sec
        16 pins
        10-micron process
        Cost: less than $100

Currently Popular Intel Pentium 4 (2.2GHz)
        Introduced December 2001
        55 million transistors
        32-bit word size
        2 ALU’s, each working at 4.4GHz

        0.13 micron process
        Targeted use: PC’s and low-end workstations
        Cost: around $600

Moore’s Law
        In 1965, one of the founders of Intel – Gordon Moore – predicted that the number of
         transistor on an IC (and therefore the capability of microprocessors) will double every
         year. Later he modified it to 18-months




Enhancing the capability of a microprocessor
The computing capability of a microprocessor can be enhanced in many different ways:
    By increasing the clock frequency
    By increasing the word-width
    Improving the architecture

Computer Software

          The HW needs SW to be useful; the SW needs HW to be useful
         When the user needs something done by the computer, he/she gives instructions in the
          form of SW to computer HW

Machine Language

         Machine language, though readily understood by microprocessors, is very difficult to write
          in for human programmers

Language Translators

         Human programmers write programs in a language that is easy to understand for them
Software Development
         The SW development process involves many steps, and coding, that is typing the
          instructions in a high-level language is only a small part of that process – taking-up only
          around 15% of the effort




Two Major Types of Software
         System SW
          Programs that generally perform the background tasks in a computer. These programs,
          many times, talk directly to the HW
         Application SW
          Programs that generally interact with the user to perform work that is useful to the user.
          These programs generally talk to the HW through the assistance of system SW

         Examples:
          Windows , Mac , OS , Linux , Unix , Solaris , DOS , CP/M , VMS
Firmware
      Firmware consists of startup and a few low-level I/O routines that assist the computer in
         finding out and executing the rest of the OS
      On IBM-compatible PC’s, it is called BIOS
Utilities
      Computer programs that perform a particular function related to computer system
         management and maintenance
         Examples:
         1- Anti-virus SW
         2- Data compression SW
         3- Disk optimization SW
         4- Disk backup SW

Language Translator

   1- Compiler translates the program written in a HLL in one go.
   2- nterpreter translates the HLL program one statement at time.
Device Drivers
    A computer program that facilitates the communication between the computer and a
       peripheral device (e.g. printer, mouse, etc.)
Application Software
Application SW are programs that interact directly with the user for the performance of a certain
type of work
     Scientific/engineering/graphics SW
        Mathematica; AutoCad; Corel Draw
     Business SW
        The billing system for the mobile phone company

        Shrink-Wrapped SW
           -You can just go to a shop and buy it
        Custom-built SW
           -You cannot just go to a shop and buy it; you have to find someone who can develop it
         for you
Who Owns Software?

        Generally, although a piece of SW that is being used by millions, it is not owned by any of
         them! Instead, it is owned by the maker of the SW

Three Main Types of Software Licenses

    1. Proprietary – Most software on a Windows PC or a Macintosh belongs to this category
    2. Freeware – Most software on a Linux PC belongs to that category
    3. Shareware – the category which lies between the above two categories

Proprietary SW License

        The user needs to pay the maker of the SW for buying a license that allows the user to
         use the SW

Types of Proprietary Licenses

        Single-user license
        Multi-user license
        Concurrent-user license
        Site license

Freeware SW License

    Allows the user free use of the SW

Open-Source SW License

        Some authors give away the machine code only, which is extremely difficult to modify, if
         at all!

Shareware SW License

        Allows the user free use of the SW, but with a request that the user pay the author a
         small amount (US$10-50) if the user is satisfied with the SW

Trialware

Interactive Forms (1)
        Without forms, a Web site is “read-only” – it just provides information to the user

Interactive Forms (2)
        Can be simple or very complex
        Are always placed between the <BODY> and </BODY> tags of a Web page

Interactive Forms (3)
        Text fields
        Check boxes
        Buttons

Server-Side Scripts
        Are programs that reside on Web servers

        Process that info and take appropriate action
         Examples:
         CGI scripts on Unix servers
         ASP scripts on Windows servers

Application Software
         Application software are programs that interact directly with the user
         They generally do not talk directly to the hardware

Classification According to the Mode
Interactive-mode
        The user runs the program on the computer and keeps on interacting with the computer
        while the program runs
                         Example: Word processor
Batch-mode
        The user starts the program and the computer processes the provided data and produces
        results without any further intervention of from the user
                         Example: Payroll

Client Side Script
New Concept: Client-Side Scripts
    Small programs that are a part of the Web page and run on the user’s (client’s) computer
    They interact with the user to collect info or to accomplish other tasks
    Once it has been collected, they may help pass the collected info on to a server-side
      script

Advantages of Client-Side Scripting
    Reduced server load as it does not have to send messages to the user’s browser about
       missing or incorrect data
Disadvantages
    Client-side scripts do not work with all browsers
    Some user intentionally turn scripting off on their browsers

JavaScript
Why JavaScript?
  JavaScript can be used (along with HTML) to develop interactive content for the Web
What is JavaScript?
   A programming language specifically designed to work with Web browsers

        It is designed to be used for developing small programs – called scripts –

Definition of Algorithm
Sequence of steps that can be taken to solve a given problem is called Algorithm.

Examples:

Addition
Conversion from decimal to binary
The process of boiling an egg
The process of mailing a letter
Sorting
Searching
Origin of the Term “Algorithm”
The name derives from the title of a Latin book: Algoritmi de numero Indorum
That book was a translation of an Arabic book: Al-Khwarizmi Concerning the Hindu Art of
Reckoning
That book was written by the famous 9-th century Muslim mathematician, Muhammad ibn Musa
al-Khwarizmi

Al-Khwarzmi
Al-Khwarizmi lived in Baghdad, where he worked at the Dar al-Hikma
Dar al-Hikma acquired and translated books on science and philosophy, particularly those in
Greek, as well as publishing original research
The word Algebra has its origins in the title of another Latin book which was a translation of yet
another book written by Al-Khwarzmi:
       Kitab al-Mukhtasar fi Hisab al-Jabr wa'l-Muqabala



Greedy Algorithm
An algorithm that always takes the best immediate, or local solution while finding an answer
Greedy algorithms may find the overall or globally optimal solution for some optimization
problems



Deterministic Algorithm
An algorithm whose behavior can be completely predicted from the inputs
That is, each time a certain set of input is presented, the algorithm gives the same results as any
other time the set of input is presented.

Randomized Algorithm

Strategy for Sorting
Repeat the following steps while the list is un-sorted:
Start with the first object in the list
Swap it with the one next to it if they are in the wrong order
Repeat the same with the next to the first object

Keep on repeating until you reach the last object in the list



Q: Is this the only possible algorithm for sorting a list?
A: Certainly not! In fact this one (called the “Bubble sort”) is probably the worst (reasonable)
algorithm for sorting a list – it is just too slow

Some of things that JavaScript cannot do!
      The following file ops. on the client computer:
            -- Read               -- Modify
           -- Rename              -- Delete
           -- Create
      Create graphics (although, it does have the ability to format pages through HTML -
         including the placement of graphics)
Some of the things that JavaScript can do!
      Control the appearance of the browser
      Control the content and appearance of the document displayed in the browser
      Store & modify a limited amount of data about the user in the form of client-side “cookies”
Client-Side JavaScript
Although a version of JavaScript exists that can be used to write server-side scripts, our focus in
this course will only be on client-side scripting
Case Sensitivity
      HTML is not case sensitive. The following mean the same to the browser:
         <HTML> -- <html>
         <Html> -- <htMl>
      JavaScript is case sensitive. Only the first of the following will result in the desired
         function – the rest will generate an error or some other undesirable event:
         onMouseClick -- OnMouseClick
         onmouseclick -- ONMOUSECLICK
JavaScript is Object-Based
        Everything that JavaScript manipulates, it treats as an object – e.g. a window or a button

Not Object-Oriented!

        JavaScript is not a true object-oriented language like C++ or Java
        It is so because it lacks two key features:
            -- A formal inheritance mechanism
            -- Strong typing

Types of Objects
        JavaScript objects
           -- Objects that are part of JavaScript
           -- Examples: window, document
        Browser objects
           -- Objects that contain info not about the contents of the display, but the browser itself
           -- Examples: history, navigator

        User-defined object

Event Handlers

        “Events” are actions that occur as a result of user’s interaction with the browser
        We use “event handlers” [e.g. onMouseOver(), onClick()] to design Web pages that can
         react to those events

    1. Batch Programs
    2. Event-Driven Programs

         Batch Programs
         These are typically started from a shell (or automatically via a scheduler) and tend to
         follow a pattern of:
         Initialize internal data
         Read input data
         Process that data
         Print or store results

         Event-Driven Programs
         Examples: GUIs, microwave, camera
         The system sends events to the program and the program responds to these as they
         arrive.

Programming Language

A vocabulary and set of grammatical rules for instructing a computer to
perform specific tasks
All programs consists of:

         Sequence of instructions
         Conditionals
         Loops

These may contain:
Data
Input/output (print, etc)
Operations (add, divide, etc)
Examples of Prog. Languages

Types of Prog. Languages

High level Programming Languages
Low Level Programming Languages

High-level programming languages, while simple compared to human languages, are more
complex than the languages the uP actually understands,
Assembly languages are similar to machine languages, but are easier to program in as they
allow a programmer to substitute names for numbers




Machine languages consist of numbers

Interpreters: immediate response, but execute code slowly.
Compilers: Takes longer to compile, but super-fast execution.

Programming SW Development
SW Design Methodology ?
The set of (often flexible) rules and guidelines a team of developers follow to construct
reasonably complex SW systems
     Object Oriented Design
     Structured Design



Object-Oriented Languages
Programming languages specifically designed to make it easy to implement object-oriented
designs
Examples: Smalltalk, C++, Java

Variables
Variables give us the ability to manipulate data through reference instead of actual value.
Variables are names assigned to values.

Identifiers
         Identifiers are names used by JavaScript to refer to variables (as well as objects,
         properties, methods, and functions!). An identifier must begin with an alphabetical
         character (a-z or A-Z) or the underscore “_” character.
