Connectivity

1. Ports

   • mouse and keyboard ports PS/2
     • Mini din 6 connector
   • Video ports-Analog and Digital
     • Analog signal(varying levels, such as seen with an audio signal. which is the older method. Digital Signal 1's and 0's. Because the computer uses all digital signals,sending 1's and 0's is more efficient than having to convert the 1's and 0's to an analog signal.
     • Video Port Summary
   • VGA port
     • female port is sometimes advertised as an HD-15 OR DE-15 Port. The VGA cable has a DB-15 males end that attaches to the DE-15 port
   • DVI port
     • DVI has three rows of square holes. DVI is used to connect flat panel digital displays.
     • Single link DVI-Dual Link DVI
       • Single link allows coonections at a resolutions of 1920x1080. Dual Link more pins are available to send more signals thus allowing higher resolutions.
       • DVI -D,DVI-I,DVI-A
         • DVI-D-used for digital video connectivity. DVI-I can be used for both digital and analog monitors and it is the most common. DVI-A is the less common type which is used for analog connectivity only.
     • HDMI
       • Upgrade to DVI is High Definition Multimedia Interface, a Digital interface that can carry audio and video over the same cable. Mini HDMI, or Micro HDMI connectors are used with devices such as cameras, tablets and smartphones.
       •            HDMI  Connectors A= 19-pin port on a TV or PC that can have a Catergory 1(standard) or Catergory(High Speed). B= 29-pin port used with very high resolution displays. C=19-pin mini port(2.42mm x10.42mm)found on mobile devices D= 19-pin micro port(2.8mm x 6.4mm) found on mobile devices.
   • Display port
     • Display port can send and receive video,audio or both types of signals simultaneously. The port is designed to primarily output to display devices such as(T.V,Computer Monitors,and Home Theater devices).
     • Converters
       • Passive converter-can be used to convert single-link DVI or HDMI port. Active converter-used to convert Dual-link.
       • Passive and Active Cables
         • Passive Cables-is one that does not contain a chip like active cables. Active Cables- have chips that boosts the signals, thus allowing cables to be thinner and to support sending signals further and faster than passive cables.
   • Thunder Bolt port
     • The ThunderBolt Port used in Apple computers is the same connector as the Mini-Display Port. ThunderBolt 3 will use the USB Type C. In addition to carrying video signals, a ThunderBolt cable can also be used to carry audio signals and data to external storage devices(CD's,DVD's,Blu ray,Flash drives.
