How to find the best motherboard that suits you..... A guide on motherboard and its various parts.

I promised to write a post on motherboards in one of my previous posts. So here it is… After reading this post, you will get a fair idea about the motherboard and its various components.
Before you buy a motherboard, you should decide which cpu you’re going to buy.

The Socket
The socket on the motherboard supports the cpu. Intel and AMD use different types of sockets. Intel uses Land Grid Array (LGA) and AMD uses Pin Grid Array (PGA).
Socket 775 and socket 1156 are the most common sockets for Intel processors (as of now). Socket 1156 is the latest one which offers support to the Core series (i3,i5,i7) processors.
Socket AM2+ and AM3 are the common AMD sockets. AM3 is the latest model that offers support to CPUs like Phenom II.

Bus Speed
The Front Side Bus (FSB) is a system that connects the cpu to the northbridge. The northbridge contacts the memory (RAM) and other components and passes the data to the cpu. The speed of the FSB plays a very important role in the overall performance of a computer. So choose a motherboard with a high speed FSB. This will enable you to install a faster cpu in the future, if needed. Overclocking is another advantage which I’m not going to cover here.

The Chipset
The north-bridge and the south-bridge together constitute the chipset. The

north-bridge is the more important component as it is more involved with the cpu. The chipset plays a major role in the graphics performance of machines without graphics cards, as it accommodates the IGP (integrated/onboard graphics processor). Other functions include memory controller (regulates communication between the CPU and RAM), graphics controller (handles communication between graphics card and CPU), onboard audio etc. So try to buy a motherboard that has a good chipset. Go to a manufacturer’s website and you will be able to find the chipset that suits your needs.
Most part of the above paragraph doesn’t hold true for the high end models of core series CPUs from Intel (i series). The GPU (Graphics Processing Unit), memory controller and the graphics controller are integrated the to CPU’s die itself!
AMD had moved the memory controller to the cpu die a long time ago. But nothing much has happened since.

Memory Slots
It is into the memory slot that you insert the RAM. DDR, DDR2 and DDR 3 are the three types of RAM that are in use today and DDR3 is the fastest of them all. The type of RAM which the motherboard uses will be specified in the manual itself. A slot can accept only one type of RAM. Always go for the motherboard that supports the latest RAM module. No. of slots and max. memory support are the two other factors. That is not very relevant for a desktop user as most of the boards these days have at least 4 slots and can support a minimum of 4 GB which is more than enough. If you’re a pro. gamer or somebody who frequently uses memory intensive programs, you may consider these 2 factors also.

Peripheral Interfaces
As you know, all the peripherals of a computer are connected to

the motherboard. There are ports inside and outside the motherboard to which we connect the peripherals. Different types of ports are described below:

IDE port    : predecessor of SATA port. Used for connecting optical drives,HDD.

SATA port: a lot quicker than PATA. Used in all modern systems.

FDD port  : Floppy disk drives are not used anymore (normally) but many motherboards still come with an FDD port. Maybe for advanced users. But even bios flashing is too easy these days so you need not worry about it.

USB port    : Generally used for connecting external devices viz. pen drives, external hdd, printers to the pc. USB 3.0 is the latest . Make sure that you buy a board that supports USB 3.0. It’s about 10x faster than USB 2.0.       

FireWire port: Very similar to USB, but offers better speed (not on paper but in reality) and networking capabilities. Almost all the modern motherboards come with a firewire (IEEE 1394) port.

Other ones like parallel port, serial port etc are standard across all motherboards.


Expansion slots
These are the array of slots located on the south and central part of the board. You will generally

see only 3 types of expansion slots theses days : PCI, PCI x1 express and PCI x16 express slots. The PCI slot houses devices like LAN card, sound card etc., the PCI x1 express is not commonly used. Certain TV tuner cards and graphics use it. PCI x16 express slot is used by graphics cards. Make sure that you have at least two PCI slots and one PCI x16 express slot on your motherboard.

Manufacturer’s reputation
It’s always better to buy a crucial component like motherboard from a reputed manufacturer. Reliability and post sales service are the major reasons. Gigabyte, ASUS, MSI and Intel are some of the leading manufacturers. If you ask me, I will always recommend Gigabyte motherboards. They often add useful features to their motherboard. It is also the most stable motherboard out there.

Final words
Hope that I managed to cover almost all the factors you need to consider while buying a motherboard. A good motherboard alone cannot make a super fast system. It’s a combined work. CPU, RAM and Hard Disk are the three other important members of the network. Make sure that the other three are also in good condition.

Advantages of Motherboard In a Computer

The motherboard, or main board, is normally the first component to be installed in the case. All additional adapters will be installed directly on the motherboard, and storage device (drives) will be attached to it by wide ribbon cables. There are a dozen well-known motherboard manufacturers and hundreds of lesser-known brands. PCs are not named for their motherboards, but by their CPUs, such as Pentium 4 or Athlon. The CPU and the memory (RAM) require no connections to anything else in the case other than the motherboard, and can therefore be mounted on the motherboard before it is installed in the case. Not surprisingly, the motherboard is the largest component you will install in the case, and is often the most expensive.

The modern ATX (AT extension) motherboard provides many basic function: It passes power from the power supply to the installed adapters, CPU, and memory modules; provides connection ports for the keyboard, mouse and printer; and integrates all the supporting function necessary to make the CPU into a computer. Most jobs handled by the motherboard go on entirely in the background, transparent to the user and remarked on only if there is a problem. The motherboard function that you should always keep in mind when building your PC is that it acts as the communications infrastructure for the entire computer. The motherboard is crisscrossed by information superhighways, some as wide as 64 lanes, which move information and instructions from one component to another.

Motherboard

For example, to display a checkbook ledger stored on your system last week, the CPU (which does most of the decision making) asks the hard drive, via a motherboard superhighway, to send this information to immediate memory for use. The requested information is moved from the hard drive to the memory (RAM) via a motherboard superhighway, where the CPU operates on it via a special expressway and formats it for presentation. The information is then sent via another superhighway to the video adapter, which translates it into television-type signals for the monitor. You don't have to keep track of which superhighway, called a bus, is involved in every operation, but it is important to understand that the various push-together connections you will make to the motherboard form vital bridges for the information flow.

Manufacturers in a “reinventing the wheel” process do not design motherboards. The design of the motherboard is largely controlled by the choice of the chipset-the one or two highly integrated chips that support the CPU. Although the CPU can be seen as the decision maker, it doesn't actually carry out the policing of all the motherboard superhighways (and back roads) by itself. The chipset handles all the support functions for the motherboard largely in automatic mode, just like nervous system of the human body maintains our vital function even while we sleep. The level of support offered by the chipset defines the capabilities that can be built into the motherboard, including what speeds will be possible for the CPU and memory. There are far fewer chipset manufacturers than motherboard manufacturers, and CPU manufacturers always design a companion chipset of their own to go with their CPUs.

Apple's Magic Mouse

Apple once again shocks the cyber world by introducing Magic mouse. It is the world's first Multi-Touch mouse. It began with iPhone. Then came iPod touch. Then MacBook Pro. Intuitive, smart, dynamic. Multi-Touch technology introduced a remarkably better way to interact with your portable devices — all using gestures. Now with Magic Mouse Apple succeeded in bringing gestures to the desktop with a mouse that’s unlike anything ever before.

It has a button less multitouch surface where the mouse itself is a button. You can scroll in any direction with one finger, swipe through web pages and photos with two, and click and double-click anywhere. Inside Magic Mouse is a chip that tells it exactly what you want to do. Which means Magic Mouse won’t confuse a scroll with a swipe. It even knows when you’re just resting your hand on it.

Magic Mouse uses powerful laser tracking that’s
far more sensitive and responsive on more surfaces than traditional optical tracking. That means it tracks with precision on nearly every surface — whether it’s a table at your favorite cafe or the desk in your home office — without the need for a mousepad.

Magic Mouse connects to your Mac via Bluetooth wireless technology, so there’s no wire or separate adapter to worry about. Pair Magic Mouse with your Mac and enjoy a reliable and secure connection up to 33 feet away. When you combine Magic Mouse with the Apple Wireless Keyboard, you create a workspace free of
annoying cables.



And because Magic Mouse is wireless, it can venture beyond the confines of your desk. A quick flick of the on/off switch helps conserve battery power while Magic Mouse is tucked in your bag. Even when it’s on, Magic Mouse manages power efficiently, by detecting periods of inactivity automatically.

When you use gestures, it’s as if you’re touching what’s on your screen. For instance, swiping through web pages in Safari gives you the feeling of flicking through pages in a magazine. And scrolling with Magic Mouse isn’t your everyday scrolling. It supports momentum scrolling (similar to iPhone and iPod touch), where the scrolling speed is dictated by how fast or slowly you perform the gesture.

System Requirements

• Mac computer with Bluetooth wireless technology
• Mac OS X v10.5.8 or later with Wireless Mouse Software Update 1.0* or Mac OS X v10.6.1 or later with Wireless Mouse Software Update 1.0
• Existing keyboard and mouse for setup
• Two AA batteries (included)
