Term 962
Video Graphics Array (VGA) is a standard analog display interface used to connect computers to monitors, projectors, and other display devices.
Term 963
Video Random-access Memory (VRAM) is a special type of memory used by a graphics card to store image data that the computer screen displays.
Term 964
Violation mode is a port security feature on Cisco switches that defines what action is taken when an unauthorized device attempts to connect to a secured switch port.
Term 965
A Virtual IP Address (VIP) is a logical IP address shared among multiple devices to provide high availability and load balancing.
Term 966
Virtual desktop infrastructure (VDI) is a technology that hosts desktop operating systems on a central server, allowing users to access a full desktop environment remotely from any device over a network.
Term 967
Virtual Extensible LAN (VXLAN) is a network virtualization technology that uses encapsulation to create isolated, scalable, Layer 2 networks across a Layer 3 infrastructure.
Term 968
A Virtual IP (VIP) is a floating IP address shared among multiple servers or network devices to provide high availability and fault tolerance without being tied to a single physical interface.
Term 969
A virtual machine (VM) is a software-based emulation of a physical computer that runs an operating system and applications just like a real machine, but is isolated and managed by a hypervisor on a host system.
Term 970
A virtual network is a software-based network that connects computers, servers, and devices over the internet or within a cloud environment, simulating a physical network without requiring dedicated hardware.
Term 971
Virtual Routing and Forwarding (VRF) is a technology that lets a single physical router operate as if it were multiple independent routers, each keeping its own separate routing table.
Term 972
A VLAN (Virtual Local Area Network) is a logical grouping of network devices that behave as if they are on the same physical network segment, regardless of their actual physical location.
Term 973
A VLAN logically segments a physical network into isolated broadcast domains without requiring separate physical switches.
Term 974
A VLAN mismatch occurs when two connected network devices are configured with different VLAN assignments on the same link, causing traffic to be dropped or misrouted.
Term 975
VLAN tagging is a method used to identify which VLAN a network frame belongs to as it travels across a trunk link, allowing multiple VLANs to share the same physical connection without mixing their traffic.
Term 976
Variable Length Subnet Masking (VLSM) is a technique that allows network engineers to create subnets of different sizes within the same network, using custom subnet masks to match the exact number of hosts needed.
Term 977
VNC (Virtual Network Computing) is a cross-platform remote desktop protocol that allows a user to control another computer over a network.
Term 978
VNC is a cross-platform remote desktop protocol that allows a user to control another computer's graphical interface over a network.
Term 979
A virtual private network inside a cloud provider that lets you securely connect and isolate your cloud resources.
Term 980
VNet peering is a networking connection that links two virtual networks so they can communicate with each other as if they were a single network.
Term 981
Voice over IP (VoIP) is a technology that lets you make phone calls using an internet connection instead of a traditional telephone line.
Term 982
A Voice VLAN is a separate virtual local area network configured on a network switch to carry voice traffic, such as from IP phones, ensuring quality of service and security by isolating it from data traffic.
Term 983
VoIP (Voice over IP) is a technology that transmits voice calls as digital data packets over IP networks instead of traditional circuit-switched telephone lines.
Term 984
A Virtual Private Cloud (VPC) is a logically isolated section of a cloud provider's network where you can launch and manage resources like servers and databases with complete control over IP addressing, subnets, route tables, and security.
Term 985
A VPC endpoint is a private connection that allows resources inside a Virtual Private Cloud to access supported AWS services or external networks without going over the public internet.
Term 986
A feature that captures information about the IP traffic going to and from network interfaces in a Virtual Private Cloud (VPC).
Term 987
A Virtual Private Cloud (VPC) network is a logically isolated section of a public cloud provider's infrastructure where you can launch cloud resources in a virtual network that you define and control.
Term 988
VPC peering is a direct network connection between two virtual private clouds that allows them to communicate using private IP addresses as if they were part of the same network.
Term 989
VPC Service Controls is a Google Cloud security feature that protects the data of managed services by defining perimeters that prevent data exfiltration and unauthorized access across public networks.
Term 990
A VPN (Virtual Private Network) creates a secure, encrypted tunnel between your device and a remote server, protecting your data and hiding your online activity.
