Parts of the Motherboard
What is a motherboard?
A computer motherboard (also
known as the mainboard) is one of the most crucial components of a computer.
Computer Motherboards are essential
to a computer. All the computer components somehow connect to the motherboard.
The Power Supply powers up the motherboard and the CPU is laid inside the
motherboard. The memory is also put into the motherboard. Hard Drives, Floppy
Drives and CD/DVD players all connect to the motherboard using either the IDE
Ribbon cable or the later SATA cables. Thus a motherboard is very important for
it connects all the computer hardware components together.
Different Motherboard Components
There are many different
components on a motherboard. To find out about each different component click
on the list below. I will briefly describe each component and then explain what
that component does in a motherboard.
- CPU Socket
- CMOS
- BIOS
- Memory Slots
- Power Connectors/ cable
- IDE Connectors
- SATA Connectors
- CMOS Battery
- AGP Graphics Slot
- PCI-Express Graphics Slot
- PCI Slots
- Chipset
A computer motherboard is a
complicated component of a computer. Everything in a computer
connects to the motherboard and learning about computer motherboards is vital
if you want to understand the computer.
Computer
CPU
Computer
CPU
A computer cpu is the brain that runs a computer. CPU (Central Processing Unit)
is the core chip to a computer. It is placed in the cpu socket and
from here it forms an electrical interface with the motherboard. A CPU is the
most important part in a computer.
CPU Socket
A CPU socket is a connector built
into the motherboard where the CPU (central processing unit) goes. Most
motherboards use the PGA (Pin Grid Array) architecture which means that there
is a grid of holes, in which a particular CPU's pins will fit into.
The majority of CPUs also have a
latch. This means that the CPU slides in easily and then it grips the pins
tightly when the latch is placed down. Several of the recent LGA (land grid
array) motherboards now have pins in the socket while the CPU has contact pads
that match the pins.
A computer motherboard connects
with the CPU and forms an electrical interface with it. There are many
different sockets so it is important when purchasing a motherboard and CPU to
make sure that the CPU will fit inside the socket.
CMOS and BIOS
What is CMOS? The computer
term CMOS stands for (Complementary Metal Oxide Semiconductor).
People sometimes get confused between CMOS and BIOS,
even though they sound the same they are different, read on to find out more.
The BIOS contains the details
about your drives, their order of booting, the time and date and many other
features, and its the CMOS that remembers those settings every time you restart
or turn your computer on. It is a little bit of memory that remembers all the
BIOS settings, so that your computer won't have to be configured each time you
turn your pc on.
In the case of many computers
pressing delete or F10 in the booting process will bring you to the BIOS setup. In
the BIOS setup you can change many options. To find out what you can do visit
my page of the BIOS setup utility.
The CMOS battery powers
the CMOS Memory so that all this data won't be lost. So when your computer is
off and even when it is unplugged and moved, all the basic settings are saved
allowing for a safe fast boot.
Computer Bios
The primary function of the
Computer Bios (BasicInput/Output System)
is to identify and make sure that the major computer components such as the,CPU, Hard Drive and
Optical Drives. This prepares the computer for major functions operated by
software, such as the booting of an Operating System from a hard drive, cd/dvd, floppy or USB.
The Bios contains code needed to
run the keyboard, screen, disk drives and other functions. It is typically
stored on the ROM (Read Only Memory)
Bios, which means that if the computer suffers a major catastrophe (such as a
broken CPU, or dead hard drive) then the Bios information remains unharmed and
the computer will still be able to function after these components are
replaced.
CMOS Battery
The CMOS battery (or the motherboard battery) has a unique purpose in a computer. This page will explain what the battery is, how to change the CMOS battery and how to remove the CMOS battery and a range of other things to do with that little computer battery inside your motherboard.
Computer Memory
PCI Slots
Video Cards
Sound Card
Network Card
Computer Power
Supply
Hard Drive Connectors
RAM (Random Access Memory) or
Computer Memory is another very important component to a computer. Computer
Memory is a volatile storage device meaning that when the computer is switched
off everything stored on this temporary storage device will be lost. The more
computer memory, the better the computer will run and the better it will handle
programs and software. RAM is now generally measured in Mhz, and most commonly
seen in the types of SDRAM, DDRRAM, DDR2RAM.
AGP Graphics Slot
AGP means ‘Accelerated Graphics
Port ’,
which is the commonly used term for describing a specific point to point video
card interface that is used to connect the card to your computer’s processor
and memory. The AGP
Graphics Slot is
most commonly used for video games that require their graphics to be sent with
a data stream and calculated, as opposed to simply passing through your
computer like a TV signal does.
PCI Slots
The Peripheral Component Interconnect
slots, commonly known as the PCI slots, refers to a
computer bus. The computer bus is used by the computer to connect to peripheral
add-on devices, such as a pci video card, network cards, sound cards, tv
tuners, firewire cards, graphics cards and many other types of extension cards.
Video Cards
A video card is another
compulsory component in a computer. The information goes into the video card
and then is transmitted to the monitor where the information is displayed. Some
motherboards have the graphics card built in, but the majority need a separate
card that plugs into the motherboard.
Sound Card
A sound card is another extra
that can be added to your computer. A sound card translates signals into sounds
that can be played back through speakers. Many motherboards have a sound card
incorporated in the motherboard, but for those that don't it is possible to get
one.
Network Card
A Computer Network Card or a
LAN (Local Area Network) card is increasingly becoming more and more necessary
in world of broadband internet and home networking. LAN ports are often
incorporated on the motherboard and it is used for networking computers
together or for connecting through a router to the World Wide Web.
Computer Power
Supply
A computer power supply is a compulsory unit to a computer.
Without the power
supply a computer is
useless as it is just a case full of metal and plastic. This page will explain
the different power
cables and connectors and
how they work inside your computer.
A power cable connects from the power point to the power supply where it supply's the motherboard and
other components with power. Often there is a power switch on the back which
can be switched off to stop the power current. If this is not switched off and
even though the computer is off power will still be drawn out of the power
point (very small amount).
Hard Drive Connectors
There
are currently three connector cables in a common hard drive. These are the: IDE Ribbon Cable, SCSI Cable and the more
recent SATA Cable.
Intel Teach Elements on the go...
Here I am again doing nice stuff for my career. Teaching strategies, methods, assessment, assessment instruments, who says you know all these?
Before starting the course, I can say I did a better job in teaching. Evaluators, my past administrator told me I have the strategy in getting the attention of my class. I am a good teacher as they say... But, as I started to read the module, I doubted the way I teaches my students. Yes I did my job well, but how come I don't have/ possess what is in the module. That strikes me most. Until I found myself hooked reading the module and answering the module activities and summary tests.
Do you know what I am talking about? It is Intel Teach Element, powered by Intel and is given to teachers for free.
There I found how the proper way to assess students who possesses the 21st Century skills and use rubrics and checklist in every project.

The Poem I live by
Missing You |
by Kanya |
You were on my mind when i woke up this morning remembering your smile i guess the next time i'll see your face will take a little while i was remembering your arms around me love the way they always feel warm with you by my side i completely feel no harm i was remembering your voice makes my heart skip a beat but without you baby my whole body's weak i was remembering our times the good and the bad the funny times when you cheered me up and especially the sad remembering your eyes how they always meet mine remembering all the little things you do to make my life worthwhile i was wondering when we'll be together just us two i guess i'm missing you more than i usually do |

The Ignorant side of Me
When I was in College, I prefer not to talk, not to communicate or even not to smile. Why? because I always thought I am the ugliest among my classmates. I am the ignorant and dullest of them because I came from the province. My color is more like a burnt popcorn and they are as clear and neat as paper. I used to go around myself, eat my lunch alone in the corner of the room. No one ask me why I am like that, maybe because they feel pity on me or maybe they just talked about me when I am not around. But I appreciated their silence.
During class hours, I used to be at the back of everybody because I am scared to be called by my teachers. I am afraid of answering their questions because of my english. I cant speak english well. And I totally have stage fright when I started talking and the worst it will end up losing my idea and just standing there and dont know what to do.. HAHAY what a bad life!!!
One time during our Math class, even how terror my teacher is, even how afraid I am but still I have the guts to answer the questions... And all my classmates were really shocked and they stand and clap their hands and say... Hay salamat nitingug na jd xa! And even I am afraid I smiled at them and say Thank you for the support... They laugh and one of my classmates said naka English pa jd..
That is the biggest achievement I have those time. But mind you, it took me a month to have that courage. And thanks for my Math skills and I was able to get out of my shell.
