Comptia Itf+ Chapter 2
Web-Based Configuration
1. Look up the ip address and login address of the device. 2.After connect to the network and powering the device on use the web browser to navigate to the devices ip address. 3. Enter the username and password to gain access to the device. 4. Begin the management process.
Universal Series Bus (USB)
A common interface allow for the connection between a device and its host controller(generally a computer). Devices can range between a keyboard, flash drive, hard drive, and mouse.
Printer
A device that produces a paper or hard copy of the processing results. Pre-installed drives include a operating system. Outdated printers may need a drive manually installed.
DVI(digital visual interface)
A port used to connect data from computers to digital devices such as monitors and projectors.
VGA(video graphics array)
A single chip data cable that is responsible for analog signals to provide graphics
Docking device
A single connector that allows the host have 7 different type of peripheral connections
HDMI (High-Definition Multimedia Interface)
A standard interface for audio-video connectivity, allows for the transmission of high-definition audio and video signals.
Bluetooth
Bluetooth is open network technology standard that allows for the data transmission from fixed and mobile electronic devices over short distances.
Motherboard
Circuit board that contains all of the computer systems main components. Connects CPU, memory ,storage devices, ports, cables and i/o devices.
Expansion Slot
Connect or port inside a motherboard or riser card. Its job is the provide installation point for a hardware expansion card, expand port slots and replace low performance ports with high performance ones.
IP-Based Peripherals
Devices that needs to be connected to either a LAN or the internet. Configured through either a touch pad setup program or a built in web browser.
UEFI(Unified Extensible Firmware Interface)
Enhanced firmware as of 2014, Allows for faster startup, Supports hard drives of 2.2 tbs
FireWire
Interface bus that allows for high-speed data transfer. Frequently used to import video and audio to a computer. Primarily used in apple products
NFC (Near Field Communication)
Near-field communication (NFC) allows data to be exchanged between devices via short-range, high frequency wireless communication technology by combining the interface of a smartcard and reader into a single device.
Scanner
Optically scans imagery, text and converts it into digital imagery
Serial Advanced Technology Attachment (SATA)
Ports that connect ATA hard drives to motherboards.
ROM(Read Only Memory)
Possesses Rom(Read only Memory) chip on the motherboard. Which allows access to set up computer system at its most basic level.
Laptop Motherboards
Same as a desktop motherboard except the ports are on the edges/sides of the laptop and the use of ribbons to connect display keyboard and touchpad.
Firmware
Software that is permanently stored in a chip. The BIOS on a motherboard is an example of firmware.
S/PDIF
Sony-Philips digital interface format—a single-pin RCA phone jack used for transferring digital audio from CD and DVD players to amplifiers and speakers. (3)
Display Port
The primary function of DisplayPort is to interface between a video source and a display device like a monitor. It is capable of transmitting both audio and video simultaneously as well separately.
Wired Network
Two Types: Telephone Connector(Rj-11) is used to plug a dial up modem or a fax device into a telephone line, has 3 to 6 wires; Ethernet Connector(Rj-45) is a connecter used to connected devices to a LAN network identified by its 8 pins.
Speakers
Uses a 3.5 analog minijack. Lime green color code for inserting speakers
BIOS Firmware
Uses the rom to settle processor and memory speeds, and settles ports for drives and external connections. Runs programs that are essential to the computer. Then hands responsibility to the OS.
Driver Installation
When a device is not recognized by the OS so driver installation is required
RF(Radio Frequency)
Wireless Devices that do not use the established standards(Bluetooth, WIFI). Uses dedicated transceivers.
Thunderbolt
a port that transmits both video and data on the same port and cable. The port is shaped the same as the DisplayPort and is compatible with DisplayPort devices.
Plug-in-play
devices that begin functioning properly as soon as you connect them to your computer. No manual installation of drives needed.
Port Cluster
found near the rear end of a computer. Allows external devices to be plugged into the computer. Note the motherboard can effect the amount of ports available, the types of ports, and the types of card slots.
