Term 751
Traffic shaping is a network bandwidth management technique that controls the flow of data packets to ensure smooth performance and prevent congestion by intentionally delaying some traffic.
Term 752
A specialized hardware or virtual device used to securely and efficiently migrate large volumes of data between storage systems, often across different environments or geographic locations, without tying up production network bandwidth.
Term 753
A transfer belt is a component in laser printers that carries toner images from the imaging drum to the paper, ensuring accurate color alignment in color printing.
Term 754
A Transit Gateway is a network hub that connects multiple virtual private clouds (VPCs) and on-premises networks through a single, central gateway to simplify routing and reduce complexity.
Term 755
TFTP is a simple, lightweight protocol used to transfer files between devices on a network without the security and error-checking features of more robust file transfer methods.
Term 756
TTL (Time to Live) is a value in network packets that limits how many hops or seconds the packet can travel before being discarded, preventing infinite loops and network congestion.
Term 757
Twisted Nematic (TN) is a type of liquid crystal display (LCD) technology that uses liquid crystals twisted at a 90-degree angle to control light and create images on a screen.
Term 758
A Type 1 hypervisor is a lightweight operating system that runs directly on server hardware to create and manage virtual machines without needing a separate host OS.
Term 759
A Type 2 hypervisor is software that creates and runs virtual machines on top of a host operating system, rather than directly on the hardware.
Term 760
udev is a device manager for the Linux kernel that dynamically manages device nodes in the /dev directory, handling device insertion, removal, and event-driven configuration.
Term 761
UDP (User Datagram Protocol) is a communication protocol that sends data quickly without first checking if the receiver is ready or if the data arrived correctly.
Term 762
UDR is a user-defined routing rule that controls how network traffic moves between subnets or to external destinations in a cloud or on-premises environment.
Term 763
UEFI (Unified Extensible Firmware Interface) is a modern firmware interface that initializes hardware and boots the operating system, replacing the older BIOS.
Term 764
UEFI is the modern replacement for BIOS that controls how a computer starts up and loads the operating system.
Term 765
A Uniform Resource Locator (URL) is the web address you type into a browser to access a specific resource like a webpage, image, or file on the internet.
Term 766
A device that provides emergency power to connected equipment when the main power source fails or drops to an unacceptable voltage level.
Term 767
Universal Plug and Play is a set of networking protocols that allows devices on a network to discover each other and connect automatically without manual configuration.
Term 768
A Universal Serial Bus (USB) is a standard interface that allows you to connect devices like keyboards, mice, storage drives, and printers to a computer for data transfer and power delivery.
Term 769
A small, reversible 24-pin USB connector that supports high-speed data transfer, power delivery, and video output, used in modern devices.
Term 770
An unknown unicast is a frame sent to a switch that is destined for a MAC address the switch does not have in its MAC address table.
Term 771
Unmount is the process of safely detaching a file system or storage device from the operating system, ensuring all pending data writes are completed and system consistency is maintained.
Term 772
Unshielded Twisted Pair (UTP) is a type of copper cabling used in Ethernet networks, where pairs of wires are twisted together to reduce electrical interference, without additional metallic shielding.
Term 773
User Datagram Protocol (UDP) is a fast, connectionless network protocol that sends data without first checking if the receiver is ready or if the data arrived safely.
Term 774
A user-defined route (UDR) is a custom routing rule you create in a cloud or on-premises network to override or supplement the system's default routing behavior, directing network traffic along a specific path.
Term 775
A Variable Length Subnet Mask (VLSM) allows network engineers to divide an IP address space into subnets of different sizes, using different subnet masks for each subnet to match the exact number of hosts needed.
Term 776
Virtual Desktop Infrastructure (VDI) is a technology that hosts desktop operating systems on a central server so users can access their personal desktop environment from any device.
Term 777
Vertical alignment is the precise positioning of components or data so that they line up correctly along a vertical axis, ensuring proper connection, communication, or readability.
Term 778
