How Motherboards Work?

This text is copy from http://en.wikipedia.org

A motherboard (sometimes alternatively known as the mainboard, system board, planar board or logic board,^[1] or colloquially, a mobo) is the main printed circuit board (PCB) found in computers and other expandable systems. It holds many of the crucial electronic components of the system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard contains significant sub-systems such as the processor.

Motherboard specifically refers to a PCB with expansion capability - the board is the "mother" of all components attached to it, which often include sound cards,video cards, network cards, hard drives or other forms of persistent storage, TV tuner cards, cards providing extra USB or Firewire slots, and a variety of other custom components. (The term mainboard is applied to devices with a single board and no additional expansions or capability, such as controlling boards in televisions, washing machines and other embedded systems.)

                                

What is HDMI?

HDMI stands for High-Definition Multimedia Interface, and that's a pretty good description of what it is. In layman's terms, HDMI is a type of digital connection that's capable of transmitting high-definition video and high-resolution audio over a single cable. To do the same thing with analog cables, you'd need to connect three component-video cables plus six analog audio cables--that's a whole lot of cable clutter.

HDMI is typically used to connect a high-definition device--such as an HD DVR--to an HDTV. To make the connection, you simply put one end of the cable into the HDTV's HDMI input slot and the other end into the device's HDMI output slot. And that's it--just one cable and you're all set for the high-definition experience. If you have an AV receiver, just put it in the middle of the signal chain. The output of the AV receiver goes to the HDTV and you connect your high-definition device(s) to the AV receiver's input.

What is the difference between DDR2 and DDR3 memory?

this is copy paste from http://www.crucial.com

DDR3 is the latest-generation memory available at Crucial. It is the successor to DDR2 memory.

         Technically speaking, there are many differences between DDR2 and DDR3 memory. Electrically, DDR3 works quite a bit differently than DDR2 and also runs at 1.5v instead of DDR2's 1.8v. The benefit? This lower voltage can result in lower power consumption at comparable speeds.

         From a speed (or frequency) perspective, DDR3 picks up where DDR2 leaves off. DDR2 "JEDEC standard*" memory typically stops at around 800MHz whereas DDR3 memory starts at 800MHz—although most DDR3 memory that is available today runs at 1066MHz and 1333MHz. And 1600MHz is on the horizon. Performance DDR3 memory modules (also called overclocking memory) are already running at over 2000MHz.

          DDR2 and DDR3 memory modules differ physically as well. While they both have similar numbers of pins, the notch in the card (or PCB) is in different locations. That means a DDR3 memory module cannot be placed in a DDR2 memory socket and vice-versa.

*JEDEC, which stands for Joint Electron Devices Engineering Council, is the independent standards body that works with DRAM manufacturers to develop and publish the specifications that define how memory works. Micron, Crucial's parent company, is a member of JEDEC and sits on the Board of Directors for the organization.

About Me ^^

Hai!

Welcome to my blog ^^!

   Actually, this is my first time wrote a blog..means i'm newbie blogger's..haha..but, it's okay.. Never mind..My name is Muhammad Solahudin Bin Musa. But, my friends juz call me "SolaH"..

   I was born in Hospital Sik, Kedah Darul Aman. But, i was raised in Setiawangsa, Kuala Lumpur. I got my first education at Sekolah Kebangsaan Desa Tun Hussein Onn, from standard 1 to 6. Then, I continue my studies at Sek.Men. Raja DR.Nazrin Shah, form 1 to 5.                 

     

  Now, I studied at UiTM Negeri Sembilan..since i got an offer to continue my study at UiTM, i got a very big problem about my study..compare with school, everything was just given by teacher. But, I have  a someone that always give a big support to me. Her name is Nurul Najwa..She has teach me what topic that i didn't understand during lecture class especially Biology and Chemistry. Thanks ya coit ^^

   

   Beside that, as the other guys outside there. i also have my hobby. i like to play an DOTA..but, i'm jus a newbie in this arena. Hahaha..This game are so good and enjoying..i was well known as "BiG sMiLE^^!"

in this game, my favorite heroes is Dwarven Sniper. I like to play this hero bcoz of its skils. it,s able to kill an enemies without escaped. This is due to its ultimate skills, Assassinate. Sniper locks onto a target enemy unit, and after 1.7 seconds, fires a devastating shot that deals damage at long range.
