My Computer Glossary

SO-DIMM ——- Small Outline Dual In-line Memory Module

USB ——- Universal Serial Bus

PCI ——- Peripheral Component Interconnect

GT/s ——- Gigabit transfers per second

PAN ——- Personal Area Network (Also known as Bluetooth)

NFC ——- Near Field Communication (4cm or Less) also called Short-Distance Networking

USB-C ——- 24-Pin double-sided USB Connector
Lightning ——- 8-Pin Connector

DB-9 ——– Also called DE-9. The DB9 connector (originally named DE-9) is an analog socket, with 9 pins, from the D-Subminiatures (D-Sub) connector family. Commonly used for RS-232 signals.

3.5mm Aux —— TRRS (tip-ring-ring-sleeve) Connector

Docking Station VS Port Replicator: a docking station uses a proprietary connector to the computer, whereas a port replicator generally provides a universal solution for all laptops via USB

LCD ——- Liquid Crystal Display

LCD Technologies:
1. TN (Twisted Nematic) LCD >>> Fast Response Time (Gaming), Poor Viewing Angles
2. IPS (In Plane Switching) LCD >>> Excellent Color Representation, More expensive to Produce than TN
3. VA (Vertical Alignment) LCD >>> A good Compromise Between TN and IPS, Good Color Representation, Slower Response time than TN

OLED ——- Organic Light Emitting Diode

Fluorescent Vs. LED backlighting
CCFL ——- Cold Cathode Fluorescent Lamp
LED-Backlit LCD Display

Cellular Networks

SIM Card ——- Subscriber Identity Module

>>> 2G networks
GSM ——- Global System for Mobile Communications
CDMA ——- Code Division Multiple Access

Both of there standards were very good for voice communication, but they had very limited support for sending data over these wireless networks.

>>> 3rd Generation (Introduced in 1998)

>>> 4G and LTE
LTE ——- Long Term Evolution, Standard supports download Rates of 150Mbps
LTE-A ——- LTE Advanced, Standard supports download Rates of 300Mbps

>>> 5G, Fifth Generation Cellular Networking (Introduced in 2020)
*** Eventually 10Gbps (Best Possible scenario)
*** Slower Speeds from 100-900Mbps
IoT ——- Internet of Things, (5G network could be especially useful for Internet of Things Devices, where you have many devices on the network that need some kind of connectivity)

PRL ——- Preferred Roaming List
PIN ——- Personal Identification Number

GPS ——- Global Positioning System, Over 30 satellites currently in orbit
*** For Precise navigation, device need to be connected with 4 satellites to determine Longitude, Latitude, Altitude

MDM ——- Mobile Device Management (Ref:

PCI Slots (Peripheral Component Interconnect)
