Power Supply
/ˈpaʊər səˌplaɪ/
noun … “System that provides electrical energy in usable form.”
Power Supply is an electrical device or system that delivers controlled electrical power to an electronic load. Its primary role is to convert energy from a source—such as mains electricity, a battery, or a generator—into the specific voltage, current, and stability required by electronic circuits. Power supplies are foundational to all electronic systems, from tiny embedded devices to large data centers.
Electromagnetic Spectrum
/ɪˌlɛktroʊmæɡˈnɛtɪk ˈspɛktrəm/
noun … “Range of all possible electromagnetic wave frequencies.”
Low Level Virtual Machine
/ˌɛl ɛl viː ɛm/
noun … “Reusable compiler infrastructure built for optimization.”
LLVM, short for Low Level Virtual Machine, is a modular compiler infrastructure designed to support the construction of programming language toolchains, advanced optimizers, and code generators. Rather than being a single compiler, LLVM is a collection of reusable components that can be assembled to build Compilers, static analysis tools, just-in-time systems, and ahead-of-time pipelines targeting many hardware architectures.
Passive Optical Networking
/pɒn/
noun — "one fiber, many users, no powered middlemen."
PON, short for Passive Optical Networking, is a fiber-optic access architecture that delivers broadband services using only passive components between the service provider and end users. Instead of active electronics in the field, a single optical fiber is split to serve multiple customers, reducing cost, power usage, and maintenance complexity.
Fiber to the Home
/ˌɛf.tiː.tiːˈeɪtʃ/
noun — "fiber all the way, no copper excuses."
FTTH, short for Fiber to the Home, is a broadband access architecture in which optical fiber runs directly from a service provider’s core network to an individual residence or business. Unlike hybrid fiber deployments, FTTH eliminates copper entirely in the last mile, delivering data purely over fiber from end to end.
Fiber to the Cabinet
/ˌɛf.tiː.tiːˈsiː/
noun — "fiber close enough to make copper feel fast again."
FTTC, short for Fiber to the Cabinet, is a broadband access architecture where optical fiber runs from the service provider’s core network to a street-side cabinet, with existing copper lines completing the final connection to homes or businesses. It is a widely used compromise between full fiber deployment and legacy copper networks.
Virtual Local Area Network
/viː.læn/
noun — "the invisible walls that organize a network."
VLAN, short for Virtual Local Area Network, is a network configuration that segments a physical LAN into multiple logical networks, allowing devices to be grouped together based on function, department, or security requirements rather than physical location. VLANs improve traffic management, enhance security, and reduce broadcast domains within enterprise networks.
Wide Area Network
/wæn/
noun — "the network that stretches far beyond your office walls."
WAN, short for Wide Area Network, is a telecommunications network that connects multiple local area networks (LANs) over large geographic areas, such as cities, countries, or even continents. WANs enable data exchange between remote sites, branch offices, and cloud services, often relying on leased lines, MPLS, or Internet connections.
Distribution Point Unit
/ˌdiː.piːˈjuː/
noun — "the street-side box that delivers gigabit speeds over copper."
Online Certificate Status Protocol
/ˌoʊ.siːˈɛs.piː/
noun — "the real-time check that keeps digital certificates honest."
OCSP, short for Online Certificate Status Protocol, is a network protocol used to obtain the real-time revocation status of a digital certificate within a PKI framework. Unlike CRLs, which are periodically published lists, OCSP allows clients to query a Certificate Authority (CA) directly to verify whether a certificate is valid, revoked, or unknown.
