Hardware & Components
This storage technology has no moving parts, using flash memory to provide faster data access than a traditional hard drive.
What is an SSD (Solid State Drive)?
This protocol uses port 53 to translate human-readable domain names into numerical IP addresses.
What is DNS (Domain Name System)?
This network device routes data packets based on IP addresses, bridging the gap between a local area network and the internet.
What is a router?
This type of touch screen technology reacts to the electrical properties of the human body and supports multi-touch inputs.
What is a capacitive touchscreen?
This security practice ensures that users are only given the absolute minimum access levels required to perform their specific job duties.
What is the Principle of Least Privilege?
This component prevents a CPU from overheating by drawing heat away using a metal block and often a fan.
What is a heatsink?
This protocol automatically assigns IP addresses, subnet masks, and default gateways to client devices when they boot up.
What is DHCP?
The standard network topology where all individual computers connect directly to a single central hub or switch
What is a star topology?
This proprietary Apple cable connector was used on older iPhones before the universal transition to USB-C.
What is a Lightning connector?
This type of physical attack involves an observer looking over someone's shoulder to steal PINs, passwords, or confidential data.
What is shoulder surfing?
This type of RAM is volatile, must be constantly refreshed with electricity, and is used for primary system memory.
What is DRAM (or DDR SDRAM)?
This TCP port is used to establish an unencrypted, insecure text-based remote terminal connection
What is Port 23 (Telnet)?
This wireless standard is formally designated as 802.11ax and operates on both 2.4 GHz and 5 GHz frequencies.
What is Wi-Fi 6?
This mobile feature combines cellular, Wi-Fi, and GPS data to continuously track and identify the physical coordinates of a device.
What is geolocating (or GPS)?
A hardware or software tool that filters incoming and outgoing network traffic based on a set of predefined security rules.
What is a firewall?
A silver, coin-shaped battery on the motherboard that powers the chip holding the system's firmware settings.
What is the CMOS battery?
Operating on port 443, this protocol secures web traffic using SSL/TLS encryption
What is HTTPS?
The modular connector standard used to terminate a 4-pair unshielded twisted pair (UTP) Ethernet cable.
What is an RJ-45 connector?
This specialized component inside an older laptop screen converts low-voltage DC power into high-voltage AC power for CCFL backlights.
What is an inverter?
This wireless security encryption standard replaces WPA2 and introduces much stronger individualized data encryption.
What is WPA3?
The type of CPU socket architecture that uses pins built into the socket on the motherboard rather than on the processor.
What is LGA (Land Grid Array)?
This protocol uses ports 137-139 and 445 to allow file and printer sharing on Windows networks.
What is SMB (Server Message Block)?
This type of network cable uses glass or plastic threads to transmit data as pulses of light over very long distances.
What is fiber-optic cable?
This physical laptop lock mechanism uses a reinforced metal slot to anchor the device to a desk with a security cable
What is a Kensington lock?
A rogue wireless access point disguised as a legitimate Wi-Fi network designed to trick users into connecting so attackers can intercept data.
What is an Evil Twin?
