Computer Networking and Hardware Terminology

These flashcards cover key vocabulary from Computer Networking and Hardware concepts, aiding in the understanding of essential terms and definitions for exam preparation.

LCD (Liquid Crystal Display)

A screen technology that utilizes liquid crystals sandwiched between layers of glass or plastic to display images.

TN LCD (Twisted Nematic)

A type of LCD favored for fast response times and low power draw but known for poor viewing angles and color shifts.

IPS LCD (In-Plane Switching)

An LCD technology that provides excellent color reproduction, typically at a higher cost.

OLED (Organic Light-Emitting Diode)

A display technology that emits light from organic compounds, eliminating the need for a backlight.

CCFL (Cold Cathode Fluorescent Lamp)

A backlight technology used in laptops, requiring high voltage and providing a thicker display.

LED (Light Emitting Diode)

A type of backlight used in modern displays that is energy-efficient and allows for thinner screens.

GSM (Global System for Mobile Communications)

A 2G mobile network standard used primarily in Europe, allowing mobile communication via SIM cards.

CDMA (Code Division Multiple Access)

A protocol standard for mobile networks used by carriers in North America.

4G LTE (Long Term Evolution)

A wireless communication standard enabling faster internet speeds, supporting downloads up to 150 Mbit/s.

TCP (Transmission Control Protocol)

A reliable, connection-oriented protocol for sending data across networks.

UDP (User Datagram Protocol)

A connectionless protocol that prioritizes speed over reliability in data transmission.

HTTP (Hypertext Transfer Protocol)

The protocol for transferring data over the web, operating in unencrypted format.

HTTPS (Hypertext Transfer Protocol Secure)

The secure version of HTTP, using encryption for secure data transmission.

DNS (Domain Name System)

A system that translates human-friendly domain names to IP addresses.

DHCP (Dynamic Host Configuration Protocol)

A protocol that automatically assigns IP addresses to devices on a network.

RAID 0 (Striping)

A storage configuration that splits data across multiple drives for improved performance but offers no redundancy.

RAID 1 (Mirroring)

A storage configuration that duplicates data across two drives for redundancy.

FTP (File Transfer Protocol)

A standard network protocol used to transfer files between a client and server.

APIPA (Automatic Private IP Addressing)

A feature that assigns IP addresses in the range 169.254.1.0 to 169.254.254.255 when a DHCP server is unavailable.

LAN (Local Area Network)

A network that connects computers and devices in a limited geographical area.

WAN (Wide Area Network)

A telecommunications network that extends over a large geographical area.

VPN (Virtual Private Network)

A technology that creates a secure, encrypted connection over a less secure network.

QoS (Quality of Service)

The overall performance of a network service, particularly regarding latency, jitter, and bandwidth.
