Motherboard I/O Interfaces(Motherboard Ports) - Motherboard Built With Several Input/Output Interfaces, These Interfaces Are Largely Located On The Rare Input/Output Of The Mother Board.

  PS2 Connector Interface

For Example The PS2 Connector                             PS2 Connector Interface   The PS2 Connector Is A 6 Pin Multidin Connector. A MotherBoard Will Typically Have Two Of These. And Usually Located Towards The Top Of The Mother Board. One Connector Is For Plugging In The Mouse. This Is The Green PS2 Slot, You Can See The Above Picture.   And The Other Is For Plugging In The Keyboard Which Is The Purple Slot. The PS2 Connectors Are Older Technology And Is Slowly Being Faced Out In Favour Of The USB Port.   The Most Common Interface Of The Mother Board Is USB Port. USB Stands For Universal Serial Bus. Motherboards Will Typically Have Several USB Ports. Because There Are So Many Different Peripherals That Utilize The USB Interface. Such As Keyboards, Mice, Cameras, External Drives, And Pen Drives.   In Addition To Connectivity, The USB Port Also Supplies Electric. Power To That Specific Peripheral. Some USB Ports Are Mounted On The Rear Input/Output Panel And Some Are Located Directly On The Surface Of The Mother Board.

                                                            USB Port Interface  

USB Interface 

The First USB Interface Was version 1.0 In 1996. The Transfer Speed Was 1.5 Mb/s. version 1.1 Was Introduced In 1998 The Transfer Speed Of 12 Mb/s. version 2.0 Came out In 2001 With A Transfer Speed Of 480 Mb/s.   And The Latest version Is USB 3.0. This Has Data Transfer Speeds 5 Gb/s.  

Serial Port Interface

                                              Serial Port Interface The Other Interface That Can Be Found In Older Mother Board Is The Serial Port. The Term Serial Refers To Sending Data 1 Bit At A Time.   The Serial Port Is An Older Technology Interface Which Is Rarely Seen On New Mother Boards Today. That Then This Was Mainly Used For Connecting Terminals And Modems To Computers. But Now It Has Been Widely Replaced By The Faster USB Interface.   The Most Common Interface Of The Serial Port Is The RS-232 Standard. Which Uses The Common D-Connector Such As DE-9.  

Parallel Port Interface 

                                       Parallel Port Interface On Mother Board The Parallel Port Is The Other Interface That Could Be Found On A MotherBoard I/O Panel. It Was Mainly Used For Connecting Printers. And Like The Serial Port. It Is Also Being Faced Out And Replaced By The Faster Performance Of The USB Port.   It Uses A Wide D-Sub Connector Known As DB-25.

And Unlike Serial Ports That Send Data 1 Bit At A Time. The Parallel Port Sends Signals Symantainusly Over Several Parallel Channels.  

Video Adaptor Interface

A Video Adaptor Is The Other Interface That Could Appear On The Mother Board. Now I Say It Could Appear Because Some Mother Boards Have A Video Adaptor And Some Don't.

                                    Video Adaptor Interface    But The Mother Boards That Do Have A Video Adaptor. Then This Is Known As Integrated Video. Because The Video Adaptor And The Mother Board Are Essential One Unit. The Video Adaptor Is What Which Generates Images From Your Computer To Your Monitor. The Most Common Kind Of Port On A Integrated Video Adaptor Is VGA Which Stands For Video Graphic Array. The VGA Port Carries Analog Data It Has 15 Pins Divided Into 3 Rows And Usually Has A Blue Colour Shown In The Above Picture.   Integrated Video Adaptors Are Usually Not Very Powerful. They Are Good For No More Everyday Use With Light Applications But When Used For Extensive Graphic Application Such As Gaming They Can For Sure. That's Why A lot Of People Will Bypass The Integrated Video And Buy An After Market Video Card That Has Enough Power To Suit Their Needs.  

IEEE Connector Interface

The IEEE-1394 Connector Commonly Known As Firewire. Firewire Is Recognized By Its D Shape

                                                                      IEEE Connector Interface   And Is Commonly Used To Attach Devices Thus Digital Cameras And Printers. It Is Very Similar To A USB Port. Firewire And USB Are Both Used To Attach Peripherals And They Both Have Similar Transfer Speeds. Firewire Is Not A Popular As USB.   That's Why On A Modern Mother Board Today There Might Not Be Any Firewire Ports Or If There Are You Might Find One Or Two And Firewire Transfer Speed Of 400 Mb/Sec.  

Network Interface Card (NIC)

The NIC Or Network Interface Card Has A Port On A Mother Board Used For Networking Purposes. Such As Connecting To The Internet And Sharing Data Between The Computers. The Port Is Designed For An Ethernet Cable With An Attached RJ-45 Connector.   A NIC Provides A Computer With A Constant Dedicated Connection To A Network. An Each NIC Has Unique Identifier Called MAC Address.   The Transfer Speed Ranges From 1000 Mb/s.

                               Network Interface Card (NIC)  

Sound Card Interface

A Sound Card Is Another Type Of Interface That Could Be Found On A Mother Board An Just Like Integrated Video. If A Mother Board Has A Sound Card Built In And It Is Known As Integrated Sound.   A Sound Card Is What Which Processes Audio Through The Computer Speakers. A Basic Sound Card Has An Audio Output Port For Attaching Speakers And A Port For Microphone.

                                                      Sound Card Interface  

eSATA Port

Some Mother Boards Have A SATA Port On The Rare I/O Panel This Is Know As eSATA Port Or External SATA. eSATA Port Is For Attaching The External SATA Drive To A Computer.

                                             eSATA Port   For Example An External SATA Hard Drive. It Functions Similar To A USB And Firewire Ports. But The Transfer Speed Is Faster But The DIsadvantage Have Compare To USB And Firewire Is The eSATA Requires A Separate Power Plug To Supply The Drive With Power.   But There Is New SATA Port Called eSATAp.
