Module 3 - Introduction to Personal Computer Flashcards
This houses the internal components such as the power supply, motherboard, central processing unit (CPU), memory, disk drives, and assorted adapted cards.
Case
Refers to the physical design and look of a case.
Form Factor
Desktop computers are available in these form factors:
Horizontal Case
Full-size Tower
Compact Tower
All-in-One
Computers use this to convert AC power into a lower voltage DC power required by internal components.
Power Supply
Original power supply for legacy computer systems
Advanced Technology (AT)
Updated version of the AT Power Supply
AT Extended (ATX)
The most common power supply on the market today
ATX12V
Power supply originally designed for network servers but is now commonly used in high-end desktop models.
EPS12V
Most common voltages supplied by the power supply:
3.3V
5V
12V
It is the printed circuit board (PCB) inside the power supply to which the external cables are connected. They can be single, dual, or multi.
Rail
A power supply use these to power various internal components such as the motherboard and disk drives.
Connectors
The backbone of the computer that contains buses, or electrical pathways, that interconnect electronic components. It is also a printed circuit board (PCB).
Motherboard
Major Components on a Motherboard
- Central Processing Unit (CPU)
- Random Access Memory (RAM)
- Expansion Slots
- Chipset
- Basic Input / Output System (BIOS) Chip & Unified Extensible Firmware Interface (UEFI) Chip
- SATA Connectors
- Internal USB Connector
What does SATA stand for?
Serial AT Attachment
What does CPU stand for?
Central Processing Unit
What does BIOS stand for?
Basic Input/Output System
What does UEFI stand for?
Unified Extensible Firmware Interface
Connects a monitor to a computer using a cable. This and monitor cables transfer analog signals, digital signals, or both.
Video Port
These ports on a computer connect peripheral devices such as printers, scanners, and portable drives.
Input/Output (I/O) Ports
This component performs the same function as an adapter but also translates the signals from one technology to the other.
Converter
This component physically connects one technology to another.
Adapter
Users use this to communicate with a computer.
Input Devices
Two most commonly used input devices
Keyboard and Mouse
These input devices digitize an image or document.
ADF/Flatbed Scanner
These input devices are used for playing games.
Joystick and Gamepad
This input device is a hardware device that can be used to control more than one computer while using a single keyboard, monitor and mouse.
KVM Switch
This input device use touch or pressure sensitive screens.
Touch Screen
This is a type of digitizer that allows a designer or artist to create artwork by using a pen-like tool.
Stylus
A device that reads information magnetically encoded on the back of plastic cards.
Magnetic Strip Reader
A device that reads the information contained in the barcodes affixed to products.
Barcode Scanner
Devices identifying a user based on unique facial features.
Facial Recognition Scanners
Devices identifying a user based on unique fingerprint.
Fingerprint Scanners
Devices identifying a user based on unique voice.
Voice Recognition Scanners
Input device used with computer games, simulators, and training applications with virtual reality functionalities.
Virtual Reality Headset
It takes binary information from the computer and converts it into a form that is easily understood by the user.
Output Device
It uses computer technology to create a simulated, three-dimensional environment. Its headset completely encases the upper portion of users’ faces, not allowing in any ambient light from their surroundings.
Virtual Reality (VR)
It superimposes images and audio over the real world in real time and can provide users with immediate access to information about their real surroundings. Its headset does not close off ambient light to users, allowing them to see their real-life surroundings.
Augmented Reality (AR)
Output devices that create hard copies of files
Printers
Type of auditory output device
Speakers
Devices that capture digital images and videos
Digital Camera
Video Cameras that can be integrated into a computer.
Webcams
Device that electronically captures a person’s signature
Signature Pad
Device used on a computer to authenticate the user.
Smart Card Reader
Device that allows a user to speak into a computer and have their voice digitized.
Microphone
Recent input device that you tap to pay devices
Near Field Communication (NFC) devices and terminals
Three types of technology most monitors use:
Light Crystal Display (LCD)
Light-Emitting Diode (LED)
Organic LED (OLED)
Most video projectors use this technology
LCD or Digital Light Processing (DGL)
