Where we left off on PC Architecture
  • State of lastname_Cls5Notes.ppt
  • State of lastname_Cls5Notes.doc

Software and Applications
  • I suggest you think of these as layers of a cake
  • Software (programs) run on computing platforms
    (Mainframe, Server, PC, or microcomputer, etc.)
  • An Operating System (OS) is software that runs
    directly on computing hardware and enables
    Applications to use the functions of the hardware
    platform.
  • An Application is software that runs on an
    Operating System and enables a user to accomplish
    a task

OS

Software Layers and Components
Windows XP 2003 Operating System (OS)
Hardware
Other OSs include Vista, MAC OS, Unix, Linux

Inside the PC The Atomic Units
  • All computers are based on the binary number
    system
  • binary means 2 values
  • off or on zero or one
  • A bit or binary digit is
  • the smallest unit of memory
  • has one of two values 0 or 1
  • A byte is
  • the smallest addressable unit of memory
  • Contains 8 bits
  • Can hold values from 0 to 256 (or 28)
  • Values can be interpreted as numbers or as
    characters
  • Can be assembled to form larger units of memory

On
Off
10
Inside the PC
  • Characters are stored as numeric values called
    codes
  • The codes were standardized by the American Natl
    Std.s Institute (ANSI)
  • The standard codes were called the American
    Standard Code for Information Interchange or
    ASCII
  • ASCII provides for 256 (or 28) characters (the
    number of values a byte can hold)
  • 01000001 A
  • 01000010 B
  • etc.
  • Includes codes for upper vs. lower case letter,
    digits, punctuation, and special characters

11
Computer Memory
  • Measured in bytes
  • 1 Kilobyte 210 characters (1,000 bytes,
    actually 1024)
  • 1 Megabyte 220 characters (1,000,000 bytes)
  • 1 Gigabyte 230 characters (1,000,000,000
    bytes)
  • 1 Terabyte 240 characters (1,000,000,000,000
    bytes)
  • Two Types
  • ROM Read Only Memory (retains values without
    power)
  • RAM Random Access Memory (loses values without
    power)
  • FLASH slower RAM that retains values without
    power (Jump Drives)
  • The Original PC had 16KB of RAM memory
  • Todays PCs Need 512 MB or 1 GB of RAM
  • Keep multiple programs data files in memory
  • Graphic-intensive programs demand a lot of memory
  • Transient (erased when power turned off or fails)
  • Consider a UPS (uninterrupted power supply)

12
Other Input Devices - The Digital Camera
  • Image Memory is sized in terms of Picture
    Elements
  • A Picture Element is called a pixel
  • A pixel is a dot (point of light) in an image
  • A pixel is the smallest unit of image that can be
    addressed (turned on or off)
  • A pixel may have 1 or more bits associated with
    it
  • Pixels with 1 bit are black or white
  • Pixels with 2 or more bits may be gray scale or
    color
  • An image is stored on a photosensitive computer
    chip, which converts the image to a series of
    pixel values.
  • 3.5 megapixels is entry-level
  • 6 megapixels is a useful level
  • There is no film images are stored in memory
    the more memory the more pictures
  • 1 GB is suggested

13
Heading Styles and Simple Usage
  • Use Heading Styles to automatically produce a
    TOC TOC means ? Table of Contents
  • Heading ltlevel gt
  • ltlevel gt means the sub heading level in an
    outline sense
  • Corresponds to the default indention level
  • Can be associated with a multi-level numbering
    scheme (which we do next class)
  • Select text line to become a Chapter or
    Subsection Heading
  • Click the Heading ltgt desired in the Ribbon
    Styles Box
  • Use the increase or decrease indent icon in
    the Ribbon Paragraph Box to change the ltlevel gt

14
A Simple Automatic TOC
  • Put the cursor where you want the TOC
  • On the Ribbon Reference Tab select
  • Table of contents Pull down (no options)
  • Select design of contents
  • TOC appears
  • OR
  • Table of Contents Pull Down with control of
    options
  • Instead of selecting design of content, go to
    bottom of pane
  • Select Insert Table of Contents
  • TOC Dialog box appears
  • Select Options button
  • Set TOC level for the styles you want to see in
    the TOC
  • OK, then OK again

15

  • Making Changes
  • Modify Figure 2
  • Review diagram copying
  • Review Paste special
  • Size Adjusting
  • Printing today

Introduction to Networks
  • 1950s Computers were isolated
  • Data transported between them used physical media
  • paper tape, punched cards, magnetic tape and
    couriers
  • Early 1960s Direct Local Networking (pre-LAN)
  • Engineers started connecting local computers via
    special cables and interfaces
  • Mid 1960s Wide Area Networking (WAN)
  • started using leased telephone lines
  • special equipment to connect them across large
    distances.
  • Late 1960s Metropolitan Area Networking (MAN)
  • using public telephone lines and low speed
    modems to connect to computers.
  • The connection devices and lines taken together
    are called Networks

17
Introduction to Networks
  • 1969 Department of Defense
  • Network should operate in the face of damaged
    links.
  • The Advanced Research Projects Agency (ARPA)
    started the project
  • ARPA net was developed as a Network of
    Networks
  • Became known as the Internet in the late 1980s

The Internet and World Wide Web
  • The Internet
  • Network of networks
  • Supports addressing
  • Manages connections
  • Transports Data in packets
  • The World Wide Web
  • Began in 1991 at the European Particle Physics
    Laboratory (CERN) in Switzerland
  • A subset of all computers connected to the
    Internet which have and allow access to hypertext
    or hypermedia documents
  • Unlimited information
  • Unlimited disinformation
  • These documents contain references (links) to
    other documents which may be on a different
    computer anywhere in the world

21
A message travels the Internet
  • All that matters is the beginning and ending
    address

22
Review Heading Styles and Usage
  • To automatically produce a numbered TOC
  • Multi-level Heading numbering ltlevel .. gt
  • Setting a Multi-level Numbering System for
    Heading Styles
  • Select the very first text line that is a
    Heading 1 style
  • On the Ribbon Paragraph Box locate the
    Multi-level List pull down icon
  • Select the numbering style that looks like the
    left figure
  • 1 ? this, NOT ? 1.
  • 1.1 1.1
  • 1.1.1 1.1.1
  • 1.1.1.1.1.1 1.1.1.1.1.1

23
Generating the Automatic TOC
  • Put the cursor where you want the TOC
  • On the Ribbon Reference Tab select
  • Table of Contents Pull Down with control of
    options
  • Instead of selecting design of content, go to
    bottom of pane
  • Select Insert Table of Contents
  • TOC Dialog box appears
  • Select Options button
  • Set TOC level for the styles you want to see in
    the TOC
  • OK, then OK again
