Transcript of Computer Hardware

Motherboard
Architecture
BUS
similar to 'bus' in real world
-transfer data from on point to another

Internal Bus
External Bus
connect 'internal' components to
motherboard
connect motherboard to ''external' devices such as flash drive and
hard disk
Computer Hardware
send signals among components inside
Make everything work together
-spinal cord of computer
contain circuits and equipments such as
-CPU
-RAM/ROM

CPU
"Central Processing Unit"
brain of computer, control the working system
essential component
read, process and complete commands stored in memory
the processing power depend on its generation
ARM
RISC-Reduced Instruction Set Computer
designed and developed computer processors, microprocessors
more efficient processing power, energy and cost of the product
use in portable devices (phones,tablets,etc.) due to its low energy consumption
x86
(x86-32)
x64 (x86-64)
usually refer to 32-bit processor
64-bit processor
faster than 32-bit
powerful require lot of electricity
-64bit software can't run in 32bit processor
Example
GIGABYTE 8 Series G1-Killer
Example
Intel Haswell (Core I Gen 4)
RAM
"Random Access Memory"
short-term memory, available for the system when computer is running
So the data stored is deleted when the computer is off
It's "randomly access", we can access any memory without changing others
Types of RAM
SRAM

DRAM
PRAM
-Static RAM
-used for cache, allow us to complete tasks faster

-Dynamic RAM
-has memory cell,paired transistor and capacitor
-less expensive to produce than SRAM
-Phase-change RAM
-non-volatile, data remains when power is off
-much higher performance

Example
Corsair Vengeance 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz
Graphics Card
like small computer-has CPU and RAM
help display data from CPU on monitor as graphics
better graphics card can provide higher quality graphics
Types of Graphic Card
Integrated
PCI
AGP
PCIe
-on-board graphic card
-least powerful
-out of date, but can upgrade older system
-use PCI slots
-use AGP slots
-not as fast as PCLe
-different speed;1x, 2x, 4x,8x
-most advance- up to 16x
-use PCI-E slots
-can combine power, but may cause problems
Example
GeForce GTX 560 Ti
HDD/SSD
HDD
SSD
Hard Disk Drive
Magnetic Rotating Disk
bigger(size)
heavy
took longer to boot up/shut down
slow access to files
noisy
low durability
cheap
Solid-State Drive
Flash Memory/chips
smaller
light
fast transfer rate


no sound
high durability
very expensive
connect computer with other devices

Input/Output
USB3 (Universal Serial Bus)
-standard version, faster speed than older versions
-Bi-directional data transfer
Firewire
-provide fast data transfer
-peer-to-peer, can connect devices so that data can easily be shared

-External Serial Advanced Technology Attachment
-fast transfer rates, but need own power connector
eSATA
Thunderbolt
-high speed data transfer technology that was first introduced by Apple
PSU
Power Supply Unit
PSU "supply" power for computer so that it can work properly
it convert current from building so that it could be used by the computer
Example
SilverStone Zeus 1200W
Removable Storage
a portable device that we can store our data inside so that we can use it again in another place
can be consisted of disk, CD, thumb drive, external HDD, or Cloud Storage
Slots on Motherboard
'Advanced RISC Machine'
Integrated Devices
work faster because the CPU can directly control the on board devices
directly connected to motherboard
By Teetawat Kaweyanun M511A 32507
RAM Quantity
The capacity of data that RAM can stored.
The higher the capacity the faster the computer work.
can increase by insert more RAM into sockets

Socket
Each type of graphic card has different socket
-in both HDD and SSD data isn't removed when shut down
