Computer Architecture
即 What exactly is a PC?
v It stands for Personal Computer.
v Not all PCs are personal
computers.(Apple,Mac,Motorolla)
v PC is much more specific than Personal Computer
(IBM Family Relation).
v IBM literally invented the PC in 1981
Ch2-PC Components, Features and
System Design
v IBM controlled Development and Evolution of PC
from 1981-1987.
v PCs were either IBM-Compatible or IBM Clone.
v Since IBM lost control of PCs ,who Controls it?
Ch2-PC Components, Features and
System Design
即 Who Controls PC Software?
v Do not even hesitate to say: Microsoft.
v Because it controls the dominant OS used for PCs.
v Then it begun to control other types of PC software.
(drivers, utilities and applications).
v Many utilities originally offered by independent
companies.
Ch2-PC Components, Features and
System Design
v In the early days, IBM hired Microsoft to develop
most of the PC core software.
v IBM made the most costly business mistake in history.
v It has failed to secure exclusive rights to the DOS it
had contracted from Microsoft.
v IBM allowed Microsoft to sell the same MS-DOS
code to any other company interested.
Software Copyright and Hardware
Patterns.
v Software enjoys copyright protection.
v Hardware is protected only by patters which is
much more difficult, time-consuming and expensive
to obtain.
v In US patterns expires 20 years after filling it.
v Almost any one could duplicate the IBM hardware
because it was not wholly patterned.
Ch2-PC Components, Features and
System Design
v the difficult part of copying IBM PC was the
software (BOIS).
v Compaq and Phoenix Technology developed a
legal way around this problem.
v It is called Clean Room approach to reverse
engineering.
Ch2-PC Components, Features and
System Design
即 Who Controls PC Hardware?
v IBM controlled the Hardware till 1987.
v since then Intel has ben responsible for creating and
inventing newer hardware designs.
v Intel became dominant processor supplier after IBM
chose Intel 8088 in 1981.
v In 1994 Intel became the largest motherboard
manufacturer in the world.
Ch2-PC Components, Features and
System Design
v Intel had also a hand in setting some PC hardware
standards:
愀 PCI (Peripheral Component Interconnect) local bus
interface.
愀 AGP (Accelerated Graphics Port) for high performance
video cards.
愀 DMI (Desktop Management Interface).
愀 DPMA(Dynamic Power Management Architecture)
Ch2-PC Components, Features and
System Design
v Who ever controls the Operating System, controls
the PC software.
v Who ever controls the Motherboard controls the
Hardware
v So it is not surprise to call the modern PC Wintel.
Ch2-PC Components, Features and
System Design
White-Box Systems:
即 Many companies design and manufacture their
motherboards.
即 White-box system uses industry-standard
components that are interchangeable.
即 Companies selling white-box systems do not
manufacture all the system parts, but assemble them
(HP, Acer and Dell).
Ch2-PC Components, Features and
System Design
PC Design Guides:
即 For several years Intel and Microsoft released PC
XX DESIGN GUIDE.
即 The documents were guidelines for companies
developing products that work with Windows.
即 Designed for Windows logo requirement.
Ch2-PC Components, Features and
System Design
System Types:
即 Can be broken down based on:
愀 Design.
愀 Width of processor bus FSB.
愀 Width of internal registers (16-bit,32-bit,64-bit).
愀 Width of the data bus (8,16,32,64-bit).
Ch2-PC Components, Features and
System Design
即 Confusion can arise in the processors width.
愀 some refer it to how many bits of data can be read or
written at a time Data Bus Width.
愀 Some refer to it how many bits of data can be operated at
a time Internal Registers Size.
Ch2-PC Components, Features and
System Design
System Components:
即 Modern PC is both simple and complicated, How?
即 It is simple: many components have been integrated.
即 It is complicated: each part performs many more
functions.
Ch2-PC Components, Features and
System Design
即 Basic PC Components:
愀 Motherboard.
愀 Processor.
愀 Memory(RAM).
愀 Case.
愀 Power Supply.
愀 Floppy Drive.
愀 Hard Drive.
愀 CD/DVD Drive.
愀 Keyboard.
愀 Mouse.
愀 Video Card.
愀 Monitor.
愀 Network/Modem.
