Term 452
A multifunction printer is a single device that combines printing, scanning, copying, and sometimes faxing into one machine.
Term 453
Multiple Input Multiple Output (MIMO) is a wireless technology that uses multiple antennas at both the sender and receiver to increase data throughput and connection reliability without needing more bandwidth or power.
Term 454
Multiprotocol Label Switching (MPLS) is a data-carrying technique that uses short path labels instead of long network addresses to route packets quickly and efficiently across a WAN.
Term 455
A Mutual Non-disclosure Agreement is a legally binding contract between two parties where both agree to keep each other's confidential information private and not share it with outsiders.
Term 456
A Network Access Control List (NACL) is a stateless firewall that controls inbound and outbound traffic at the subnet level in a virtual private cloud.
Term 457
A name server is a specialized server that translates human-readable domain names into machine-readable IP addresses so that computers can find each other on a network.
Term 458
A Named ACL is a list of rules applied to a network device, identified by a name instead of a number, that controls which traffic is allowed or blocked based on source and destination IP addresses, protocols, and port numbers.
Term 459
NAT (Network Address Translation) is a method that allows multiple devices on a private network to share a single public IP address when accessing the internet.
Term 460
A NAT Gateway is a managed AWS service that allows instances in a private subnet to connect to the internet or other AWS services while preventing the internet from initiating connections back to those instances.
Term 461
A NAT instance is a virtual machine that forwards traffic from a private subnet to the internet, performing Network Address Translation (NAT) so that private instances can reach the internet without exposing them to inbound connections.
Term 462
NAT overload is a form of network address translation that allows many devices on a private network to share a single public IP address by using unique port numbers to track each connection.
Term 463
A native VLAN is the default VLAN assigned to a trunk port that carries untagged traffic for backwards compatibility with devices that do not understand VLAN tagging.
Term 464
A Native VLAN mismatch occurs when two connected switches have different Native VLANs configured on the trunk port, causing control traffic like CDP, DTP, and BPDUs to be sent on the wrong VLAN and potentially creating security vulnerabilities or connectivity issues.
Term 465
Near-field Communication (NFC) is a short-range wireless technology that allows two devices to exchange data when they are touched or brought within a few centimeters of each other.
Term 466
Neptune is a fully managed database service by AWS designed specifically for graph database workloads, using property graph and RDF models.
Term 467
netstat (network statistics) is a command-line tool that displays active network connections, listening ports, routing tables, and network protocol statistics on a computer.
Term 468
A Network Access Analyzer is a security tool that monitors and analyzes who and what is trying to connect to a network, checking for unauthorized access and policy violations.
Term 469
A Network ACL is a virtual firewall that controls inbound and outbound traffic at the subnet level in a cloud network, acting as a stateless packet filter.
Term 470
Network Address Translation (NAT) is a method that allows multiple devices on a local network to share a single public IP address to access the internet.
Term 471
Network Functions Virtualization (NFV) is a way to replace specialized hardware network devices with software running on standard servers to make networks more flexible and cheaper to manage.
Term 472
A Network Interface Card (NIC) is a hardware component that allows a computer or device to connect to a network and communicate with other devices.
Term 473
A Network Load Balancer is a cloud service that automatically distributes incoming network traffic across multiple servers to ensure applications remain fast, available, and secure.
Term 474
A network printer is a printer that is connected to a network, allowing multiple users and computers to send print jobs to it over the network rather than requiring a direct cable connection to a single computer.
Term 475
A network profile is a collection of settings that defines how a device connects to and behaves on a specific type of network, such as public, private, or domain networks.
Term 476
A Network Security Group is a set of rules that controls inbound and outbound traffic to Azure resources like virtual machines and subnets.
Term 477
Network Time Protocol (NTP) is a networking protocol that synchronizes the clocks of computers and devices over a network to a common reference time source, typically Coordinated Universal Time (UTC).
Term 478
Network topology is the physical or logical arrangement of devices, cables, and data paths in a computer network.
Term 479
NetworkManager is a software utility in Linux-based operating systems that simplifies the management of network connections by automatically handling configuration, switching, and connectivity tasks for both wired and wireless networks.
Term 480
New Technology File System (NTFS) is a modern file system developed by Microsoft that controls how data is stored, organized, and accessed on Windows-based hard drives and other storage devices.
