What is DRAM (or DDR SDRAM)
This type of RAM is volatile, must be constantly refreshed with electricity, and is used for primary system memory.
What is DNS (Domain Name System)
The DNS (Domain Name System) is a decentralized, hierarchical naming system that translates human-readable website names (like google.com
What is a network switch?
a high-speed networking device that operates at the Data Link Layer (Layer 2) of the OSI model to connect multiple devices together on a single Local Area Network (LAN)
What is an inverter
an electrical device that converts Direct Current (DC) electricity into Alternating Current (AC) electricity
What is a heatsink?
a passive thermal component designed to absorb and dissipate excess heat away from high-temperature electronic or mechanical devices
What is Port 23 (Telnet)
the standard network port dedicated to Telnet, a legacy network protocol used to establish unencrypted, text-based remote management connections over the Internet or a Local Area Network (LAN).
What is APIPA?
a built-in feature of modern operating systems (such as Windows) that automatically assigns a temporary IP address to a computer or device when a DHCP server cannot be reached
What is the CMOS battery?
a small, coin-cell lithium battery located directly on a computer's motherboard that provides continuous, uninterrupted electrical power to the Complementary Metal-Oxide-Semiconductor (CMOS) RAM chip
What is DHCP?
a network management protocol used to automatically assign IP addresses and other vital network configuration parameters to devices connecting to a network
What is an RJ-45 connector?
a standardized 8-pin physical interface used to terminate twisted-pair cables for Ethernet networking
What is an SSD (Solid State Drive)?
a modern mass-storage device that uses non-volatile flash memory to read, write, and store data permanently
: What is SSH (Secure Shell)?
a cryptographic network protocol used to securely connect to and manage remote computers, servers, and network infrastructure over an unsecured network
What is a router?
a physical or virtual network device that forwards data packets between entirely different computer networks
What is LGA (Land Grid Array)?
a surface-mount packaging format used for integrated circuits—most notably computer microprocessors—where the connection pins are located inside the socket on the motherboard rather than on the underside of the processor itself
What is HTTP?
the foundational Application Layer protocol used to transmit data across the World Wide Web
What is fiber-optic cable
a high-speed data transmission cable composed of up to thousands of incredibly thin strands of glass or plastic fibers enclosed within a protective casing
