6BUS
- 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.
7Processor 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.
8RAM (Random Access Memory)
- SDRAM Synchronous Dynamic Random Access Memory
- SDRAM actually synchronizes itself with the
CPU's 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 chip's data throughput. DDR-SDRAM also
consumes less power.
9Types 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
10Do 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 wasn't 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
computer's 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.
11IDE 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.
12CD-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
13USB/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)

15Maintenance, 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.
16Hands 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.
17Maintenance, 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).
18CRT 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

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
polarizer's 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
