Connectors and plugs

  1. 1. Connectors and Plugs Things you need to know
  2. 2. Connection A connection is a term that describes the link between a plug or connector into a port or jack. For example, your monitor, mouse, and keyboard all make a connection to the computer before they will be able to work.
  3. 3. Connecting Connecting - Describing the process of connecting a plug, wire, or other device to the computer. For example, I'm connecting my computer to the Internet.
  4. 4. Connections Connections - An overall description of all available ports and jacks (more than one) on a computer.
  5. 5. Connector Connector - The description of the end of the cable that connects to the computer.Centronics, DB, and DIN are good examples of types of connectors.
  6. 6. Connect, connected, and connecting Connect, connected, and connecting - This term can also be used in software, for example, when a user gets onto the Internet they are connecting to another computer to establish a connection.
  7. 7. IDE- Integrated Drive Electronics • Integrated Drive Electronics or IBM Disc Electronics, IDE is more commonly known as ATA or Parallel ATA (PATA). It is a standard interface for IBM compatible hard drives and CD or DVD drives.
  8. 8. A picture of what an IDE cable looks like, and the IDE channels it connects to on the motherboard.
  9. 9. EXPANSION SLOT Alternatively referred to as a bus slot or expansion port. An expansion slot is an opening located inside a computer on the motherboard or riser board that allows additional boards to be connected.
  10. 10. COMPUTER EXPANSION SLOTS • AGP - Video card • AMR - Modem, Sound card • CNR - Modem, Network card, Sound card • EISA - SCSI, Network card, Video card • ISA - Network card, Sound card, Video card • PCI - Network card, SCSI, Sound card, Video card • PCIe - Video card • VESA - Video card
  11. 11. Many of the above expansion card slots are obsolete. You're most likely only going to encounter AGP, PCI, and PCIe when working with computers today. In the picture below, is an example of what expansion slots may look like on a motherboard.
  12. 12. SerialATA, SATA 1.0 was first released in August2001 and is a replacement for the Parallel ATA interface used in IBM compatible computers. SerialATA is capable of delivering 1.5 Gbps (1500 MBps) of performance to each drive within a disk array. Serial ATA, SATA
  13. 13. Serial ATA, SATA cable
  14. 14. SCSI- SMALL COMPUTER SYSTEM INTERFACE, Short for Small Computer System Interface, SCSI is pronounced as "Scuzzy"and is one of the most commonly used interface for disk drives that was first completed in 1982.
  15. 15. SCSI CONNECTORS The below illustrations are examples of some of the most commonly found and used SCSI connectors on computers and devices and illustrations of each of these connections. SCSI CONNECTORS back of Hard disk SCSI CONNECTORS male/Female
  16. 16. Short for Video Graphics Array, VGA is a popular display standard developed by IBM and introduced in 1987. VGA provides 640 x 480 resolution color display screens with a refresh rate of 60Hz and 16 colors displayed at a time. If the resolution is lowered to 320 x 200, 256 colors are shown. VGA DB9 Male/Female RS232 Cable
  17. 17. Short for Bayonet Neill Concelman connector, a BNC connector is a type of connector used with coaxial Ethernet cable. The connector is bayonet-style, meaning that it is put in then turned and locked in position. This connector is commonly used on a Token Ring network BNC connector
  18. 18. A Composite Cable Or RCA Cable is an audio/video cable with yellow, red, and white connectors on each end. They connect a VCR, DVD player, gaming system, or other audio/video device to a TV. The yellow connector is for video and the red & white connectors are for audio (red for the right speaker, white for the left speaker) RCA cable
  19. 19. Digital Visual Interface, DVI is a video display interface. It was developed to be an industry standard for transmitting digital video content to display devices at resolutions as high as 2560 x 1600. Common devices that utilize the DVI connection are computer monitors and projectors. DVI can even be used with someTVs DVI connector DVI plug/Port
  20. 20. FireWire Alternatively referred to as IEEE-1394, FireWire is a digitalbus with a bandwidth of 400-800 Mbps. It can handle up to 63 units on the same bus, and is hot swappable. Users more familiar with USB can consider FireWire similar to USB, as they has many similarities. Like USB, FireWire has dozens of different devices such as removable drives and cameras.
  21. 21. Short for High Definition Multimedia Interface,HDMI is a connector and cable capable of transmitting high-quality and high-bandwidth streams of audio and video between devices. For example, between a HDTV and DVD or Blu-ray player. HDMI HDMI cable/Port
  22. 22. Short for Musical Instrument Digital Interface, MIDI is a standard for digitally representing and transmitting sounds that was first developed in the 1980s. The MIDI sound is played back through the hardware device or computer either through a synthesized audio sound or a waveform stored on the hardware device or computer. The quality of how MIDI sounds when played back by the hardware device or computer depends upon that device's capability. Musical Instrument Digital Interface, MIDI MIDI cable use in connecting musical keyboard
  23. 23. The parallel port is found on the back of IBM compatible computers and is a 25-pin (type DB-25) computer interface commonly used to connect printers to the computer. PARALLEL PORT Parallel connector (as indicated) Parallel port with printer logo
  24. 24. A sound card is an expansion card or IC for producing sound on a computer that can be heard through speakers or headphones. Although the computer does not need a sound device to function, they are included on every machine in one form or another; either in an expansion slot (sound card) or on the motherboard (onboard). SOUND CARD
  25. 25. Digital Out (White or Yellow) (words: "Digital" or "Digital Out") - Used with surround sound or loudspeakers. Sound in or line in (Blue) (Arrow pointing into waves) - Connection for external audio sources, e.g. tape recorder, record player, or CD player. Sound out or line out (Green) (Arrow pointing out of waves) - The primary sound connection for your speakers or headphones. This sound card also has a second (black) and third (orange) sound out connector. Microphone or Mic (Pink) (Microphone) - The connection for a microphone or headphones. MIDI or joystick (15 pin yellow connector) - Used with earlier sound cards to connect MIDI keyboard or joystick.
  26. 26. USES OF A COMPUTER SOUND CARD • Games • Audio CDs and listening to music • Watch movies • Audio conferencing • Creating and playing Midi • Educational software • Business presentations • Record dictations • Voice recognition
  27. 27. Universal Serial Bus, USB Short for Universal Serial Bus, USB (pronounced yoo-es- bee) is a standard that was introduced in1995 by Intel, Compaq, Microsoft and other computer companies. USB 1.x is an external bus standard that supports data transfer rates of 12Mbps and is capable of supporting up to 127peripheral devices.
  28. 28. USB transfer speeds USB 2.0, also known as hi-speed USB, was developed by Compaq, Hewlett Packard, Intel,Lucent, Microsoft, NECand Philips and was introduced in 2001. Hi- speed USB is capable of supporting a transfer rate of up to 480 Mbps and is backwards compatible, meaning it is capable of supporting USB 1.0 and 1.1 devices and cables. USB 3.0 also known as Super Speed USB is the latest version of the USB protocol. Most new computers feature USB 3.0 ports built-in, offering data transfer speeds of up to five gigabits per second. USB 3.0 improved upon the USB 2.0 technology with speed and performance increases, improved power management and increased bandwidth capability (providing two unidirectional data paths for receiving and sending data at the same time).
  29. 29. USB connector variations USB connectors come in many shapes and sizes as there are many different devices that utilize them. Every version of USB connector including standard, Mini, and Micro have two or more variations of connectors.
  30. 30. • Camera • External drive • iPod or other MP3 player • Keyboard • Keypad • Microphone • Mouse • Printer • Joystick • Jump drive aka Thumb drive • Scanner • Smartphone • Tablet • Webcams Today, there are millions of different USB devices that can be connected to your computer. Below are just a few of the most common USB devices you'll likely find and use.
