BUS

• The bus is a pathway over which data travels
  between various internal system components. The
  front-side bus (FSB) is the segment of the system
  bus that carries data between RAM and the CPU it
  generally has the greatest effect on overall
  benchmark performance. A system with
  high-performance processors and other components
  should also have a fast front-side bus.

7
Processor or CPU

• The CPU can do three things.
• A microprocessor can perform mathematical
  operations like addition subtraction
  multiplication and division.
• A microprocessor can move data from one memory
  location to another.
• A microprocessor can make decisions and jump to a
  new set of instructions based on those decisions.
  
• Clock speed - Determines how many instructions
  per second the processor can execute. This is
  indicated in megahertz MHz.

8
RAM (Random Access Memory)

• SDRAM Synchronous Dynamic Random Access Memory
  - SDRAM actually synchronizes itself with the
  CPUs bus and is capable of running at 133 MHz.
• DDR RAM Double Data Rate SDRAM - Supports data
  transfers on both edges of each clock cycle (the
  rising and falling edges) effectively doubling
  the memory chips data throughput. DDR-SDRAM also
  consumes less power.

Types of SDRAM and DDR RAM

• SDRAM (168 pin DIMM)
• PC100 100MHz bus
• PC133 133MHz bus
• PC150 150MHz bus
• DDR SDRAM(184 pin DIMM)
• PC1600 200MHz bus
• PC2100 266MHz bus
• PC2400 300MHz bus
• PC2700 333MHz bus
• PC3200 400MHz bus
• PC3500 433MHz bus
• PC3700 466MHz bus
• PC4000 500MHz bus
• PC4200 533MHz bus
• PC4400 550MHz bus

Do I need ECC non-ECC Buffered or Unbuffered

• ECC Parity - There are two different types of
  memory module error checking parity and ECC
  (Error Checking and Correction). Parity modules
  have an extra chip that detects if data was
  correctly read or written by the memory module by
  adding additional bits and using a special
  algorithm. However it will not correct the
  error. ECC modules perform the same kind of error
  detection however if the data wasnt properly
  written the extra chip will correct it in many
  cases depending on the type of error. Non-ECC
  (also called non-parity) modules do not have any
  error-detecting features. Error Correction Code
  modules are the best type of memory for
  high-performance systems running mission critical
  applications.
• Buffered Registered Memory - Buffered modules
  contain a buffer to help the chipset cope with
  the large electrical load required for large
  amounts of memory. The buffer electrically
  isolates the memory from the controller to
  minimize the load that the chipset sees. However
  unbuffered modules are the most common. In
  unbuffered memory the chipset controller deals
  directly with the memory. There is nothing
  between the chipset and the memory as they
  communicate. Registered modules are unbuffered
  modules containing a register which delays all
  information transferred to the module by one
  clock cycle. This is usually done on modules with
  a large amount of memory to help ensure that the
  data is properly handled. The design of the
  computers memory controller dictates which type
  of RAM must be used and buffered and unbuffered
  RAM cannot be mixed. Most buffered and registered
  modules also have ECC and are used in
  high-performance systems where it is extremely
  important that the data is properly handled.
• For most PCs you need non-ECC unbuffered RAM!
  Servers would use the ECC Buffered memory.
  Always consult your motherboard manual to
  determine the type of RAM you need.

IDE Integrated Drive Electronics

• IDE is a type of Hardware interface used to
  connect components like CD-ROM drives and Hard
  Disk Drives.
• Most motherboards have two IDE connections. The
  Primary channel and Secondary channel.
• Each channel can have two devices a Master and a
  Slave device.
• That gives us a total of 4 IDE devices.
• To set a device as Master or Slave you need to
  set the jumper on that device to the proper
  setting.

12
CD-ROM/CD-RW/DVD-RW

• CD-ROM Can only read CDs at speeds of up to
  56x
• CD-RW Can read from and write to CD media at
  speeds of 54x-32x-54x (Write-Rewrite-Read).
  CD-RWs can hold 700MB of data
• DVDRW Can read any DVD and write to only DVDR
  or DVDRW media at speeds of 16x DVD read/write
  and 48x24x48x CD-RW . DVDRWs can hold 4.7GB of
  Data
• DVD-RW Can read any DVD and write to only DVD-R
  or DVD-RW media at speeds of 16x DVD read/write
  and 48x24x48x CD-RW . DVD-RWs can hold 4.7GB of
  Data

13
USB/Firewire

• Universal serial Bus - an external bus
  (connection) standard that supports data transfer
  rates of 12 Mbps for USB 1.1 and 480 Mbps for USB
  2.0. A single USB port can be used to connect up
  to 127 peripheral devices such as mice modems
  keyboards hard drives CD-ROM drives digital
  cameras and printers.
• Firewire (IEEE 1394) A fast external bus
  (connection) standard that supports data transfer
  rates of up to 400Mbps (in 1394a) and 800Mbps (in
  1394b). A single 1394 port can be used to connect
  up 63 external devices. (Tends to be more
  expensive than USB)

Maintenance Hardware

• Use a compressed gas duster to keep the internal
  and external components of your PC free from dust
  and debris.
• Check your fans often. System cooling is of
  utmost importance. Make sure that your PC in not
  shoved to close to a wall and air circulation is
  impeded.
• When working inside your PC make sure that you
  ground yourself before starting.

16
Hands on exercise

• Open your computer case.
• Remove the RAM.
• Remove the Ethernet card.
• Unplug the IDE cable from the Primary IDE
  connector on the motherboard.
• Set the jumper on your spare CD drive (or hard
  drive ) from master to slave.
• Now put it all back the way it was.

17
Maintenance Software

• Keep your Windows operating systems up to date by
  doing windows updates.
• Keep your anti-virus software up to date.
• Run spy-ware tools to keep unwanted ad and spy
  cookies and registry hacks out.
• Run Defrag. If you have a FAT32 partition do it
  every week. If you have an NTFS partition run it
  once a month (not as critical on NTFS).

CRT vs. LCD

• Cathode Ray Tube vs. Liquid Crystal Display
• CRT
• LCD

The electron beams are emitted from an electron
beam gun in the neck of the cathode ray tube.
Being negatively charged these electrons are
attracted by a high voltage electric field that
is generated at the front of the CRT. To guide
the electrons to strike and illuminate the proper
phosphor areas on the front inside surface of the
CRT a deflection yoke is implemented to deflect
each beam. http//www.eizo.com/support/faqs/crt/q
a01.asp
LCDs are created from two glass plates separated
from each other at a distance of a few microns.
Plates are filled with liquid crystal then
sealed together. The top plate is colored with an
RGB pattern to create a color filter. Then
polarizers are glued to both plates. The LCD
cell is assembled into a module by adding the
backlight driver electronics and
frame. http//www.lcdmonitors.philips.com/lcdmoni
