Serial, Parallel, and Game ports have for the most part been replaced by USB ports. USB or Universal Serial Bus is less bulky, faster, can be hot swapped, and up to 127 devices can be used. Early Mice used serial connectors and keyboards used a 5 pin bulky DIN connector. Modern Mice and Keyboards use PS/2, USB, or wireless type connectors. A NIC or Network Interface Card is what connects your computer to a local or distance network or the internet. The NIC converts parallel signal from the motherboard system bus into serial signal for the internet cable. A dial up Modem is used to connect to the internet. At speeds of 56kbps, it is the slowest way to connect. Modern computers use two types of video output ports, VGA port (analog) and DVI port (digital). In addition an S-video port might be equipped as an output for the TV. There are two types of monitors on the market today, CRT and LCD. CRT Monitors or Cathode Ray Tube uses a tube similar to old television screens. CRT Monitors contain an electric charged storage capacitor, deadly if touched. LCD Monitors or Liquid Crystal Display uses TFT technology or Active Matrix. There are several specifications to conceder when choosing a monitor. Such as Screen Size, Contrast Ratio, Refresh Rate Interlacing (CRT), Response Time (LCD), Resolution, and much more. Modern Computers also have Video Buses and Video Cards. In today’s systems there are three types’ printers, Dot Matrix, Inkjet, and Laser. The first Type is Dot Matrix; this Printer uses a cluster of pins that strike the ink ribbon much like a type-writer. This form of typing is used for multi-part printing. The second type is Inkjet; this printer uses two different forms of printing. The first is Thermal Bubble and the other is Piezoelectric Technology. The third type is Laser; these printers use a six step printing process. Some of these steps involve 600 volts of positive and
