Logic bomb
A logic bomb is malicious code inserted into a software system that lies dormant until a trigger, like a specific date or event, sets off its harmful payload.
Logic gate
A logic gate, also called an electronic logic gate, is an electronic device that computes a Boolean function of its binary inputs, the elementary building block of digital circuits.
Logic optimization
Logic optimization transforms Boolean logic networks into equivalent networks with less area, delay, or power, and is a core stage of logic synthesis in electronic design automation.
Logic Pro
Logic Pro, formerly Emagic Logic, is a digital audio workstation by Apple for recording, editing, and mixing music on Mac and iPad, acquired with Emagic in 2002.
Logic programming
Logic programming is a programming paradigm in which a program is a set of logical sentences and computation proceeds by inference, best known through the language Prolog, created in 1972.
Logic synthesis
Logic synthesis automatically converts an RTL or behavioral hardware description into a functionally equivalent gate-level netlist, using Boolean optimization and technology mapping, and is verified by logic-equivalence checking.
Logic-geometric programming
Logic-geometric programming (LGP) is an optimization-based formulation of combined task and motion planning in robotics, proposed by Marc Toussaint at IJCAI in 2015.
Logical data warehouse
Logical data warehouse (LDW, virtual data warehouse): a Gartner-coined analytical architecture in which a semantic/virtualization layer over a traditional EDW integrates diverse sources via reusable metadata without physical consolidation; supports AI and RAG workflows.
Logical Volume Manager (Linux)
The Logical Volume Manager (LVM) is the standard volume manager of the Linux kernel, combining physical disks into volume groups from which flexible logical volumes are created.
LogiMAT
LogiMAT is an annual international trade fair for intralogistics solutions and process management, held each spring at Messe Stuttgart in Stuttgart, Germany since 2003 and ranked as Europe's largest such show.
Login
Login, also called logon or signing in, is the process of presenting credentials to authenticate an account with a computer service, after which the user receives an authenticated session.
Logis-Tech Tokyo
Logis-Tech Tokyo (国際物流総合展, International Logistics Comprehensive Exhibition) is a Japanese trade show for material handling and logistics equipment, held at Tokyo Big Sight since 1994 and among the largest such exhibitions in Asia.
Logistics
Logistics is the management of the forward and reverse flow and storage of goods, services, and information from origin to consumption, spanning transportation, warehousing, inventory, and order fulfillment.
Logit attribution
Logit attribution, most often called direct logit attribution (DLA), is an interpretability method for transformer language models that decomposes output logits into contributions from each attention head and MLP layer.
Logit lens
The logit lens is an interpretability technique for transformer language models, introduced by nostalgebraist in 2020, that applies the model's unembedding matrix to intermediate-layer hidden states.
Logit masking
Logit masking is a decoding-time technique that sets disallowed tokens' logits to negative infinity before sampling, so a language model's output conforms to a grammar such as a JSON Schema.
Logitech
Logitech International S.A., also known as Logicool, is a Swiss computer peripherals manufacturer founded in 1981 in Apples, Switzerland, and known for mice, keyboards, webcams, and gaming gear.
Logitech MX Master 4
The Logitech MX Master 4 is a wireless productivity mouse unveiled by Logitech on September 30, 2025, featuring haptic feedback, an Actions Ring of shortcuts, and 70-day battery life.
Logitech Unifying receiver
The Logitech Unifying receiver is a small USB dongle, introduced by Logitech in 2009, that pairs with up to six compatible wireless mice and keyboards on one receiver.
Logjam (computer security)
Logjam is a man-in-the-middle downgrade attack against TLS, disclosed in 2015, that forces weak 512-bit export-grade Diffie-Hellman key exchange and breaks it to read traffic.
LogMeIn Hamachi
LogMeIn Hamachi is a closed-source hosted VPN service that creates virtual local area networks over the internet, popular for multiplayer gaming; it was acquired by LogMeIn in 2006.
Logo (programming language)
Logo is a programming language designed for education, a Lisp dialect created in 1967 at BBN by Seymour Papert and colleagues, best known for its turtle graphics.
Logseq
Logseq is a free, open-source knowledge management and collaboration platform that stores notes as interlinked blocks, runs on desktop, web, and mobile, and emphasizes privacy and user control.
Logstash
Logstash is Elastic's open source server-side data processing pipeline, the L in the ELK stack, started by Jordan Sissel in 2009. It uses input, filter, and output plugin stages with 200+ plugins to ingest, transform, and ship events.
Lohagad (लोहगड)
Lohagad, or Lohagad Fort (लोहगड), is a hill fort in the Western Ghats near Lonavala, Maharashtra, India, built by the 10th century and seized by Shivaji in 1648.
Loi Climat et Résilience
The Loi Climat et Résilience is a French climate law of August 2021 that turns the Convention citoyenne pour le climat's proposals into binding rules on housing, transport, and consumption.
Loitering munition
A loitering munition, also called a suicide drone or kamikaze UAV, is an expendable uncrewed aircraft with a built-in warhead that loiters over a target area before crashing into it.
LoJack
LoJack is a stolen vehicle recovery system using a hidden radio transmitter that lets police track and recover stolen cars, first deployed in Massachusetts in 1986.
Lok Ma Chau (cable landing point)
Lok Ma Chau is a cable landing point at Hong Kong's northern boundary with Shenzhen, where terrestrial fiber-optic systems cross into mainland China rather than a coastal submarine station.
Loki (rocket)
Loki, known as the Loki Dart, was an American solid-propellant rocket that failed as an anti-aircraft weapon and became a widely used meteorological sounding rocket in the 1950s and 1960s.
