Term 842
An SOA record is a DNS resource record that specifies authoritative information about a DNS zone, including the primary nameserver and administrator email.
Term 843
A software-defined network (SDN) is a networking approach that separates the control plane (how traffic is directed) from the data plane (where traffic moves), allowing network administrators to manage and optimize traffic flow centrally through software instead of relying on individual hardware switches and routers.
Term 844
A Software-defined Wide Area Network (SD-WAN) is a virtual network architecture that uses software to manage and optimize the connections between branch offices and data centers across a wide geographic area.
Term 845
A SOHO is a small network, typically in a home or small business, using consumer-grade equipment to share internet and local resources.
Term 846
A solid-state drive (SSD) is a storage device that uses flash memory to save data permanently, with no moving parts, making it much faster and more durable than a traditional hard disk drive.
Term 847
A sovereign region is a physically and logically separate set of cloud data centers within a single country, designed to meet strict data residency and compliance requirements imposed by local laws.
Term 848
A Switch Port Analyzer (SPAN) is a feature on network switches that copies traffic from one or more ports to a monitoring port for analysis without disrupting normal network operations.
Term 849
The process by which switches in a network with redundant paths select a single root bridge and block certain ports to prevent loops while ensuring all devices can still communicate.
Term 850
Hardware output devices that convert electrical audio signals into sound waves so humans can hear audio from a computer system.
Term 851
The Shortest Path First algorithm calculates the most efficient path through a network by building a map of all routers and links.
Term 852
SPICE (ISO/IEC 15504) is a framework for assessing and improving software process capability, not a network protocol.
Term 853
SQL is a standard programming language used to manage, query, and manipulate relational databases by issuing commands like SELECT, INSERT, UPDATE, and DELETE.
Term 854
SQL is a standardized programming language used to manage and manipulate relational databases, enabling querying, updating, and data retrieval.
Term 855
In networking, 'ss' is a command-line utility used to display detailed socket statistics, showing active connections, listening ports, and protocol information on Linux and Unix systems.
Term 856
A Solid State Drive (SSD) is a storage device that uses flash memory to save data, making computers start up and load files much faster than older hard drives.
Term 857
SSE (Security Service Edge) is a cloud-centric security framework that converges web, cloud, and network security into a single edge service.
Term 858
SSE (Security Service Edge) is a cloud-delivered security framework that converges web, cloud, and private access controls at the network edge.
Term 859
SSH (Secure Shell) is a cryptographic network protocol that provides secure, encrypted communication and remote administration between two devices over an unsecured network.
Term 860
An SSID is the public name of a Wi-Fi network that devices use to identify and connect to it.
Term 861
SSL (Secure Sockets Layer) is a cryptographic protocol that encrypts data transmitted between a client and a server to ensure privacy and data integrity.
Term 862
An SSL VPN is a virtual private network that uses the Secure Sockets Layer protocol to create an encrypted tunnel for remote users to securely access network resources over the internet.
Term 863
ST (Straight Tip) is a fiber optic connector with a bayonet-style twist-lock coupling, used for multimode and single-mode connections.
Term 864
A Standard Access Control List (ACL) is a sequential set of permit or deny rules that filters network traffic based solely on the source IP address.
Term 865
A Standard Operating Procedure is a detailed, written set of step-by-step instructions that describes how to perform a specific task or process consistently and safely.
Term 866
A network topology where each device is directly connected to a central hub or switch, and all data passes through that central point.
Term 867
A Start of Authority (SOA) record is a special DNS record that stores essential administrative information about a domain, including the primary name server, the responsible administrator email, and timing parameters for caching and updates.
Term 868
Startup Repair is a Windows recovery tool that automatically diagnoses and fixes common problems that prevent the operating system from booting properly.
Term 869
Stateless Address Autoconfiguration (SLAAC) is a method that allows a device on an IPv6 network to automatically generate its own IP address without needing a dedicated server to assign one.
Term 870
Static Network Address Translation (NAT) is a one-to-one mapping between a private IP address and a public IP address that never changes.
