Clip 1 Summary:

There are three types of ports, serial, parallel, and game ports, and they have for the most part been replaced with USB ports. USB devices are hot swappable, can daisy chain, and 127 devices may be plugged into the computer USB ports. Modern mice and keyboards use PS/2 technology unlike older predated mice and keyboards, which used serial connectors, and a 5-pin bulky din connector. The network interface card is responsible for connecting your computer to your local network, a distant network, or to the internet. The dial-up modem is the slowest possible method of connecting to the internet, and it connects to the phone line; the standard speed for a modem is 56Kbps.
Modern computers come with two types of video ports VGA and DVI, in addition may also have an S-Video port you may connect to the TV. SCSI connectors come with a variety of sizes, but the most common are the 50 pin connector for the A-type narrow SCSI cable, and the 68-pin connector for the p-type wide SCSI cable. IEEE 1394 also known as firewire uses serial communication, it is very fast, hot swappable, and is especially useful when transmitting streaming media. Multimedia devices such as microphones, earphones, and speakers are usually located at the back of the CPU, but in some cases there is a second set on the front of the computer as well.

Clip 2 Summary:

There are two types of computer monitors on the market today, the older CRT monitors, which are big and bulky and the newer LCD monitors which take up less desk space.CRT monitors use cathode ray tubes and LCD monitors use a technology called TET also referred to as active matrix. Refresh rate and response time are both terms used to refer to the amount of time it takes to create a new image on the screen. CRT monitors supports many resolutions but an LCD monitor is designed to support a fixed resolution called native resolution. Clip 2 also describes how to configure the resolution settings, and how to configure dual monitors.
