Standoffs
Small metal or plastic spacers used to raise a motherboard above the case surface, preventing electrical shorts.
Star-Bus Topology
A hybrid network topology that combines aspects of both star and bus topologies. Devices connect to a central hub (like in a star), but data follows a bus-like pathway.
Start Button
The button (usually located in the bottom-left corner of the Windows taskbar) used to access the Start Menu, programs, settings, and shut down options.
Start Menu
A central interface in Windows operating systems that provides access to applications, files, system settings, and power options.
Start Screen
The full-screen interface introduced in Windows 8 that displays app tiles instead of a traditional Start Menu.
Startup Repair
A Windows recovery tool that fixes problems preventing the operating system from booting properly, such as missing or corrupt system files.
SPI
(Stateful Packet Inspection). A firewall technology that monitors the state of active connections and makes decisions based on the context of the traffic (not just static rules).
Static IP Address
A fixed IP address manually assigned to a device that doesn’t change, useful for servers, printers, or network devices needing consistent addresses.
SAN
(Storage Area Network). A high-speed network that provides access to consolidated, block-level storage. Used primarily in enterprise environments for reliable and scalable storage.
Storage Pool
A group of physical disks combined into a single storage resource in Windows. Allows for flexible storage management using Storage Spaces.
Storage Spaces
A Windows feature that lets you create virtual drives from storage pools, with options for redundancy (mirroring, parity) and efficient use of space.
ST
(Straight Tip). A type of fiber optic connector with a bayonet-style twist lock. Common in older fiber optic networks.
Stranded Core
A type of wire made from multiple small strands twisted together. It’s more flexible than solid core, often used in patch cables.
Streaming Media
Audio or video content delivered over a network in real time, allowing users to start playback before the entire file is downloaded.
String
A sequence of characters (letters, numbers, symbols) used in programming and scripting, often representing text data.
Stripe Set (RAID 0)
A data storage method where data is split (striped) across two or more disks to improve performance. It offers no redundancy—if one disk fails, all data is lost.
Striped Volume
A type of dynamic disk volume (RAID 0) that splits data evenly across two or more drives to increase performance. It provides no fault tolerance.
Strong Password
A password that is difficult to guess or brute-force, usually containing a mix of uppercase and lowercase letters, numbers, and special characters, and being at least 8–12 characters long.
Structured Cabling
A standardized approach to building a cabling infrastructure using organized subsystems (e.g., entrance facilities, backbone, horizontal cabling) to support network hardware and ensure scalability and reliability.
SQL
(Structured Query Language). A language used for managing and querying data in relational database systems.
SQL Attack
A SQL injection attack occurs when malicious SQL code is inserted into a query through input fields to manipulate or access a database improperly.
su (Command)
Short for “substitute user” or “switch user”; a Linux/Unix command used to assume the identity of another user, typically the root user, to execute administrative tasks.
Subfolder
A folder that exists within another folder (parent folder); used for organizing files in a hierarchical structure.
Subnet Mask
A 32-bit number used to divide an IP address into network and host portions. It helps routers determine if a destination IP is on the same local network or needs to be routed elsewhere.
