CompTIA A+ 220-1201 Lesson 1

HDD, SSD, M.2 SATA, M.2 NVMe

store data on a spinning disk

high capacity at lower cost, but slower and prone to wear

no moving parts, and faster

compact and efficient

faster than M.2 SATA

utilize an imaging software

1. create an image of system on separate storage device 2. install new drive 3. copy image onto new drive

Directly copying data from one drive to another

the motherboard

LAN, provided by mini PCL or mini PCL express

PAN, short range connection, either separate or built into board

Up high- wrap around laptop screens

a physical part of a user (ie. facial recognition, retina scan, fingerprint)

additional OS configuration and hardware (ie. built in webcam or facial scanner)

small data transfer over a limited area wirelessly that is built into device

24 pin reversible connector and port that supports charging, data transfer, and video

higher power output for faster charging, inserted on either side, simpler design but a part of the apple ecosystem

extending a phones cellular network onto other devices

extending a phones cellular network for ONE device

precise input method

Tip Ring Ring Sleeve (3.5mm) (for headsets)

use external peripherals and extend existing laptop interfaces to make laptop easily removable and functional

for USB connections (no expansion card option), versatile and portable

detect touch through electrical properties in the human body. support multi-touch gestures, more durable, and better clarity

respond to pressure

detects changes in movement and orientation

compliments accelerometer by measuring rotation and angular velocity

detects when something is close to the screen and disables touchscreen and turns off display

adjusts screen brightness based on surrounding lighting conditions

antennas separate areas of the land into cells and the antennas covers a cell with certain frequencies

occurs when a device connects to a network outside of the user's home carrier (ie. when traveling abroad)

Access Point Name - dictates how the device connects to the internet and sends multimedia messages via the mobile network

Third generation wireless communication technology allows high speed wireless data transfer

Based on GSM and EDGE (Enhanced Data Rates for GSM Evolutions supports download rates of 150 Mbit/s vs. LTE Advanced (LTE-A) supports download rates of 300 Mbit/s

The fifth-generation wireless broadband technology with even higher frequencies, and a significant IOT impact making it more functional

connects to local 802.11 network and has no cellular bandwidth use but requires a local access point and has a limited distance

unique identifier than contains information about the carrier and subscriber with the capability to store data

embedded into the device and cannot be removed, but another can be added

precise navigation using satellites - a phone has to see four to determine location based on timing differences

determine location based on GPS. wifi, and cell towers

structured framework that empowers IT administrators to monitor, configure, manage, and secure a wide array of devices from a centralized console

Bring your own device. A policy allowing employees to connect personally owned devices

commonly purchased by the corporation and allows the use of the mobile device for both business and personal use

creates sperate zoned for work and personal use on a company managed device
