Study Notes
PC Components
- A computer may have various ports, including PS/2, Audio, Game port, Network, Serial, SATA, IDE, and USB.
Adapters and Converters
- Adapters and converters are used to connect different technologies.
- Adapters physically connect one technology to another, whereas converters also translate signals from one technology to another.
- Examples of adapters include DVI to VGA, USB to Ethernet, USB to PS/2, DVI to HDMI, and Molex to SATA adapters, as well as HDMI to VGA converters.
Input Devices
- Input devices allow users to communicate with a computer.
- Early input devices include keyboards, mice, ADF/Flatbed scanners, joysticks, gamepads, and KVM switches.
Optical Storage Devices
- There are three types of optical drives: CD ( Compact Disc), DVD (Digital Versatile Disc), and BD (Blu-ray Disc).
- CDs are for audio and data, DVDs are for digital video and data, and BDs are for HD digital video and data.
- Optical media can be pre-recorded (read-only), recordable (write once), or re-recordable (read and write multiple times).
- DVDs and BDs can also be single-layer (SL) or dual-layer (DL), with dual-layer media roughly doubling the capacity of a single disc.
Video Ports and Cables
- Video ports connect a monitor to a computer using a cable.
- Video ports and cables transfer analog signals, digital signals, or both.
- Examples of video ports and cables include DVI, DisplayPort, HDMI, Thunderbolt 1 or 2, Thunderbolt 3, VGA, and RCA.
Other Ports and Cables
- Input/output (I/O) ports on a computer connect peripheral devices, such as printers, scanners, and portable drives.
- Common adapter cards include Sound adapter, Network Interface Card (NIC), Wireless NIC, Video adapter, Capture card, TV tuner card, Universal Serial Bus (USB) controller card, and eSATA card.
Adapter Cards
- Computers have expansion slots on the motherboard to install adapter cards.
- The type of adapter card connector must match the expansion slot.
- Common expansion slots include Peripheral Component Interconnect (PCI), Mini-PCI, PCI eXtended (PCI-X), PCI Express (PCIe), Riser card, and Accelerated Graphics Port (AGP).
Storage Devices
- Data drives provide non-volatile storage of data.
- Data storage devices can be classified according to the media on which the data is stored: Magnetic (hard disk drive and tape drive), Solid state (solid state drive), and Optical (CD and DVD).
Storage Device Interfaces
- Storage devices inside a computer connect to the motherboard using Serial AT Attachment (SATA) connections.
- The legacy interface is Parallel ATA (EIDE).
