Study Notes

VGA Connector

  • VGA stands for Video Graphics Array
  • The VGA connector is associated with the blue color
  • The VGA connection carries an analog signal
  • When the VGA signal is extended beyond 5 to 10 meters, the screen appears distorted or fuzzy
  • The connector type for the VGA connection is a 15-pin D-subminiature connector

SCSI Connection

  • The SCSI terminator allows you to connect multiple devices to a single SCSI cable
  • SAS stands for Serial Attached SCSI
  • In the context of SCSI, a LUN (Logical Unit Number) is a unique identifier for a storage device
  • The purpose of a serial attached SCSI is to provide a high-speed, point-to-point connection between devices
  • The ribbon cable in a SCSI connection is used to connect devices to the SCSI bus

PATA and SATA Connections

  • The main difference between PATA and SATA connections is that SATA is a serial connection, while PATA is a parallel connection
  • PATA was also known as IDE (Integrated Drive Electronics)
  • The purpose of an 80-wire PATA cable is to increase data transfer speed and reliability
  • A significant advantage of SAS over traditional SCSI is its ability to provide multiple simultaneous connections
  • ATA stands for AT Attachment
  • The main difference between SAS and PATA connections is that SAS is a serial connection, while PATA is a parallel connection

PATA Cable Configuration

  • The purpose of increasing the number of wires in PATA cables is to increase data transfer speed and reliability
  • On a 40-wire cable, the device referred to as 'device 0' is the master device
  • In an 80-wire cable, the position of device 0 and device 1 is reversed
  • The missing pin and notch in a PATA connector are used to prevent incorrect installation

Device Connectivity

  • Devices that commonly use PATA technology include hard drives and CD/DVD drives
  • An example of a temporary fix using adapters and converters is using a VGA-to-DVI adapter to connect a VGA device to a DVI port
  • A newer laptop without an RJ45 port requires a USB-to-Ethernet adapter for wired Ethernet connection

Display Connections

  • DVI-D stands for Digital Video Interface - Digital
  • The purpose of a converter for VGA to DVI-D is to convert an analog signal to a digital signal
  • An adapter with DVI-A and VGA connectors enables the connection of an analog device to a digital port
  • The purpose of a DVI to HDMI adapter is to convert a digital signal to a digital signal with audio support

HDMI and DisplayPort

  • The maximum length an HDMI cable can extend before screen artifacts appear is around 30 feet
  • DisplayPort has a compatible connection with HDMI
  • DVI-D single link connection supports HD television at 60 frames per second, while dual link connection supports 85 frames per second
  • The main difference between single link and dual link DVI connections is the data transfer speed and resolution support

SATA Connection

  • The maximum data transfer speed of SATA revision 3.2 over a 1-meter cable is 16 Gb/s
  • SATA devices use a serial connection for data transfer
  • The main difference between internal SATA and eSATA is that eSATA is used for external devices
  • The different colors of SATA connectors on motherboards are used to indicate the power and data transfer speeds supported

Storage Drive Connectivity

  • A common connectivity option for external storage drives is eSATA
  • The SCSI standard supports up to 16 devices in a single chain and is used for connecting storage devices, scanners, and printers
  • SCSI ID numbers are used to differentiate between multiple devices connected to a single SCSI cable
  • iSCSI stands for Internet Small Computer System Interface and is commonly implemented in virtual systems
  • SCSI differs from SATA and PATA in terms of connectivity, as it uses a serial connection and supports multiple devices in a single chain
