100BASE-T
An Ethernet standard for 100 Mbps (Fast Ethernet) over twisted pair cabling (Cat 5 or better), using RJ-45 connectors.
1000BASE-T
A Gigabit Ethernet standard that supports 1 Gbps speeds over Cat 5e or better twisted pair cable, using all four pairs of wires.
1000BASE-TX
An alternative to 1000Base-T that uses Cat 6 cable and supports 1 Gbps, but is less commonly used due to cost and compatibility issues.
10GBASE-T
An Ethernet standard for 10 Gbps speeds over Cat 6a or Cat 7 twisted pair cables, typically used in data centers and high-speed networks.
2-in-1
A type of hybrid computer that functions as both a laptop and a tablet, typically featuring a detachable or foldable touchscreen.
3G
Mobile network technology that provides faster data rates than 2G, enabling web browsing, video calls, and mobile internet.
4G
A mobile network standard that delivers high-speed internet, supporting HD streaming, VoIP, and fast downloads on mobile devices.
5G
The latest cellular technology offering ultra-high speed, low latency, and support for IoT, autonomous vehicles, and massive device connectivity.
64-bit processing
A CPU architecture that can process data in 64-bit chunks, allowing access to more RAM (over 4 GB) and improved performance compared to 32-bit.
802.11a
An early Wi-Fi standard operating in the 5 GHz band with speeds up to 54 Mbps. Less interference than 2.4 GHz but with shorter range.
802.11ac
A Wi-Fi standard operating on the 5 GHz band, offering speeds up to 1 Gbps or more, MU-MIMO support, and wider channels for improved performance.
802.11ax
An advanced Wi-Fi standard offering higher speeds, efficiency, and capacity, operating on 2.4 GHz and 5 GHz, and supporting OFDMA and improved MU-MIMO.
802.11b
An older Wi-Fi standard using the 2.4 GHz band with speeds up to 11 Mbps; prone to interference from other 2.4 GHz devices.
802.11g
Improved over 802.11b, using the 2.4 GHz band with speeds up to 54 Mbps; backward-compatible with 802.11b.
802.11n
A Wi-Fi standard that supports both 2.4 GHz and 5 GHz, offers speeds up to 600 Mbps, and introduces MIMO (Multiple Input, Multiple Output).
AC
(Alternating Current). A type of electrical current that reverses direction periodically, used in wall outlets and most household appliances.
AUP
(Acceptable Use Policy). A document that outlines rules and guidelines for proper use of company systems and networks, helping to protect IT resources and users.
ACL
(Access Control List). A list that defines which users or systems have permission to access or modify a resource, like files, directories, or network devices.
Access Control Vestibule (Mantrap)
A secure entry area with two doors that control access to sensitive areas; users must pass one door before the next unlocks.
