Term 781
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 782
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 783
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 784
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 785
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 786
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 787
A visibility timeout is a mechanism in message queues or distributed systems that temporarily hides a message from other consumers while one consumer processes it, preventing duplicate processing.
Term 788
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 789
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 790
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 791
A virtual private network inside a cloud provider that lets you securely connect and isolate your cloud resources.
Term 792
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 793
Voice over IP (VoIP) is a technology that lets you make phone calls using an internet connection instead of a traditional telephone line.
Term 794
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 795
A volume group is a pool of storage capacity created by grouping one or more physical volumes in Linux LVM that can be carved into logical volumes.
Term 796
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 797
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 798
A feature that captures information about the IP traffic going to and from network interfaces in a Virtual Private Cloud (VPC).
Term 799
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 800
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 801
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 802
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.
Term 803
A VPN concentrator is a network device that manages, encrypts, and routes multiple VPN connections from remote users or sites into a single secure gateway.
Term 804
A VPN connection creates a secure, encrypted tunnel between a device and a remote network over the public internet, protecting data from eavesdropping.
Term 805
A VPN Gateway is a network device or service that creates an encrypted tunnel between two or more networks over the internet, allowing secure communication.
Term 806
A Web Application Firewall (WAF) is a security tool that filters, monitors, and blocks HTTP traffic to and from a web application to protect it from common attacks.
Term 807
A Wide Area Network (WAN) is a telecommunications network that connects multiple smaller networks, like local area networks, across large geographical distances.
Term 808
A Web Application Firewall (WAF) is a security tool that monitors, filters, and blocks HTTP traffic to and from a web application to protect it from common attacks.
Term 809
A webcam is a small digital camera that captures video and audio for live streaming or recording over the internet, typically used in video calls and online meetings.
Term 810
Weighted routing is a traffic management technique that distributes network requests across multiple servers or paths according to assigned numerical weights, allowing for controlled, uneven load distribution.
