Term 301
A fully managed in-memory data store service that provides Redis and Memcached for caching, session storage, and real-time data processing.
Term 302
A metadata server is a network-accessible service that provides configuration data, credentials, and instance-specific information to virtual machines running in a cloud environment like Google Cloud Platform.
Term 303
Metro Ethernet is a service that extends Ethernet networking across a metropolitan area, allowing businesses to connect multiple locations as if they were on the same local network.
Term 304
A Metropolitan Area Network (MAN) is a network that connects multiple locations across a city or large campus, providing high-speed communication like a single large network.
Term 305
Microsegmentation is a network security technique that divides a data center or cloud environment into small, isolated segments to control traffic between workloads, reducing the attack surface.
Term 306
Microservices is an architectural style where a software application is built as a collection of small, independent services, each handling a specific business function and communicating over a network.
Term 307
MPLS (Multiprotocol Label Switching) is a data forwarding technology that uses short path labels instead of long network addresses to direct data efficiently across a network.
Term 308
MSS (Maximum Segment Size) is the largest amount of data, in bytes, that a device can receive in a single TCP segment, excluding the TCP and IP headers.
Term 309
mTLS (mutual Transport Layer Security) is a security protocol where both the client and the server authenticate each other using digital certificates before exchanging data.
Term 310
MTU (Maximum Transmission Unit) is the largest size of a single data packet that can be sent over a network without needing to be fragmented.
Term 311
Multi-AZ refers to a deployment model where resources are replicated across multiple Availability Zones within a cloud region to ensure high availability and fault tolerance.
Term 312
A Multi-AZ deployment runs identical copies of your application or database across two or more physically separate data centers (Availability Zones), ensuring that if one data center fails, another takes over automatically with no downtime.
Term 313
Multi-AZ RDS is a database deployment option that automatically maintains a synchronous standby replica in a different Availability Zone to provide high availability and automatic failover.
Term 314
Multi-region refers to a deployment strategy where IT resources, applications, or data are hosted in multiple geographic locations to improve availability, disaster recovery, and performance.
Term 315
Multi-Region architecture is a deployment strategy where cloud resources are hosted in two or more geographically separate data center regions to improve availability, disaster recovery, and reduce latency for global users.
Term 316
A fiber optic connector that allows multiple optical fibers to be connected and disconnected quickly by simply pushing the connector into place, with a small push-pull tab for removal.
Term 317
Multilevel security is a computer security approach that allows users with different clearance levels to access data at different classification levels on the same system, while preventing unauthorized access.
Term 318
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 319
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 320
Network Access Control (NAC) is a security technology that enforces policies to control which devices and users can connect to a network.
Term 321
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 322
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 323
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 324
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 325
Neptune is a fully managed database service by AWS designed specifically for graph database workloads, using property graph and RDF models.
Term 326
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 327
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 328
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 329
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 330
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.
