(24 cards)
MU-MIMO
(Multi-User, Multiple Input, Multiple Output). A wireless technology used in Wi-Fi routers (802.11ac and newer) that allows multiple devices to receive data simultaneously, improving efficiency and network speed.
mv
the move command in Linux and macOS
NAT
(Network Address Translation). A process that allows multiple devices on a private network to share a single public IP address. It helps conserve IP addresses and adds a layer of security.
Native Resolution
The fixed number of pixels a display can show. Running at native resolution ensures maximum clarity and the best image quality.
NFC
(Near Field Communication). A short-range wireless communication technology (usually under 4 cm) used for contactless payments, data exchange, and device pairing (e.g., Android Beam, Apple Pay).
Near Field Scanner
A device that uses NFC to scan and read information from NFC-enabled cards or devices, often used in access control and mobile payments.
net
A Windows command-line utility used for managing network resources like users, groups, services, and connections (e.g., net user, net view, net stop).
net use
A command-line tool in Windows used to connect to shared network resources, like a shared folder or printer (e.g., net use Z: \server\share).
NetBIOS
(Network Basic Input/Output System). An older protocol used for network communication and name resolution on local networks, often in Windows file sharing.
netstat
(Network Statistics). A command-line tool used to display active network connections, routing tables, and protocol statistics. Helpful in troubleshooting and monitoring network activity.
Network
A system that allows devices to communicate and share resources (like files, printers, and internet). Includes both LANs (local) and WANs (wide area).
Network and Internet (Windows Setting)
A section in the Windows Settings app where users can configure Wi-Fi, Ethernet, VPN, data usage, and other network-related settings.
NAS
(Network Attached Storage). A dedicated file storage device connected to a network, allowing multiple users or clients to store and retrieve data from a centralized location. Often used for backups and file sharing.
Network Connection
A link between a device and a network, either wired (Ethernet) or wireless (Wi-Fi), that enables communication and data transfer.
Network Documentation
Detailed records of a network’s hardware, software, topology, IP schema, configurations, and procedures. Used for troubleshooting, upgrades, and audits.
Network ID
The portion of an IP address that identifies the network (as opposed to the host). Determined by the subnet mask, it’s used to route traffic correctly.
NIC
(Network Interface Card). A hardware component that allows a device to connect to a network. Can be wired (Ethernet) or wireless (Wi-Fi), and may be built-in or a separate expansion card.
Network Protocol
A set of rules and conventions that allow devices to communicate over a network (e.g., TCP/IP, FTP, HTTP). Ensures data is transmitted correctly.
Network Topology Diagram
A visual representation of a network’s layout, showing devices, connections, and communication paths. Helps with planning, troubleshooting, and documentation.
Nit
A unit of brightness for displays, where 1 nit = 1 candela per square meter. Higher nits mean a brighter screen, useful for visibility in bright environments.
Nonvolatile
Describes storage that retains data even when power is off (e.g., SSDs, HDDs, ROM). Contrast with volatile memory like RAM, which loses data when powered off.
Notification Area
Part of the Windows taskbar, typically in the bottom-right corner, that shows system and application notifications, network status, volume, and other background processes.
nslookup
(Name Server Lookup). A command-line tool used to query DNS servers and obtain domain name or IP address information. Useful for DNS troubleshooting.
NTFS
(New Technology File System). The default file system for Windows that supports permissions, encryption, compression, large files, and journaling. More advanced than FAT32 or exFAT.
