Video 1.07 talks about all of the different ports and connections on a desktop computer. The video gives an explanation of each port and what they connect to, also what each port looks like and how many devices can connect to it. Video 1.07 also talks about some of the internal ports and connections that give us external ports connections.
Serial ports- a serial communication physical interface through which information transfers in or out one bit at a time.
Parallel Port- a parallel communication physical interface. It is also known as a printer port or Centronics port.
Nic- a computer hardware component that connects a computer to a computer network.
USB- a bus for connection, communication, and power supply between computers and electronic devices.
SCSI- a set of standards for physically connecting and transferring data between computers and peripheral devices. The SCSI standards define commands, protocols and electrical and optical interfaces.
IEEE 1394- a serial bus interface standard for high-speed communications and isochronous real-time data transfer.
Video 1.09 talked about the 2 most common types of computer monitors, and the different characteristics they have. Also the video explains video buses, how they work and the different interfaces they use. The video also explains some of the ways to troubleshoot computer monitors.
CRT Monitor- a vacuum tube containing one or more electron guns and a fluorescent screen used to view images.
LCD Monitor- a variant of a liquid-crystal display that uses thin-film transistor technology to improve image qualities such as addressability and contrast.
Native Resolutions for LCD-XGA 1024x768, SXGA 1280x1024, UXGA 1600x1200, WUXGA 1920x1080.
Contrast Ratio- a property of a display system, defined as the ratio of the luminance of the brightest color (white) to that of the darkest color (black) that the system is capable of producing.
AGP- Accelerated Graphics Port is a high-speed point-to-point channel for attaching a video card to a computer's motherboard.
PCI Express- Peripheral Component Interconnect Express is a high-speed serial computer expansion bus standard designed to replace the older PCI, PCI-X, and AGP bus standards.
Video 1.11 is about the different types of printers there, the many interfaces they have and how printers work. It also talks about spooling and how it affects your computers performance.
Printer-a peripheral which makes a representation of an electronic document on physical media.
DOT Matrix Printer- a type of computer printing
