1. Anterior Cruciate Ligament (ACL)

Description: The Anterior Cruciate Ligament (ACL) is one of the major ligaments in the knee joint that provides stability and helps control the forward movement of the tibia (shin bone) in relation to the femur (thigh bone). ACL injuries are common in sports that involve sudden stops, changes in direction, or direct blows to the knee, often requiring surgical reconstruction and rehabilitation to restore function and stability to the knee joint.

2. Access Control List (ACL)

Description: An Access Control List (ACL) is a security mechanism or list of rules that defines the permissions or restrictions for accessing resources, files, directories, or network services in computer systems, networks, or applications. ACLs specify which users, groups, or systems are allowed or denied access to specific resources based on predefined criteria such as user identity, role, or access rights.

3. Association for Computational Linguistics (ACL)

Description: The Association for Computational Linguistics (ACL) is a professional organization or scholarly association dedicated to the advancement of research and education in the field of computational linguistics, natural language processing (NLP), and language technologies. ACL organizes conferences, publishes academic journals, and promotes collaboration among researchers, practitioners, and educators in the interdisciplinary field of computational linguistics.

4. American Civil Liberties Union (ACLU)

Description: The American Civil Liberties Union (ACLU) is a nonprofit organization and advocacy group dedicated to defending and preserving individual rights and liberties guaranteed by the Constitution and laws of the United States. ACLU focuses on issues such as civil rights, freedom of speech, privacy rights, criminal justice reform, and reproductive freedom through litigation, lobbying, and public education efforts.

5. Asynchronous Connectionless Link (ACL)

Description: Asynchronous Connectionless Link (ACL) is a wireless communication protocol used in Bluetooth technology to establish point-to-point or point-to-multipoint connections between devices for data transmission. ACL enables devices to exchange data packets asynchronously without requiring a predefined connection or synchronized timing, allowing for flexible and efficient communication in Bluetooth networks.

6. Adaptive Cruise Control (ACL)

Description: Adaptive Cruise Control (ACL) is an automotive safety feature or driver assistance system that automatically adjusts a vehicle’s speed to maintain a safe following distance from the vehicle ahead. ACL systems utilize sensors, radar, or cameras to detect the distance and relative speed of nearby vehicles, automatically applying brakes or throttle to keep the vehicle at a safe distance from potential collisions.

7. Access Control Layer (ACL)

Description: Access Control Layer (ACL) is a component or module in computer networking and security systems responsible for enforcing access control policies and managing user permissions for accessing network resources, services, or applications. ACLs are implemented in routers, switches, firewalls, and servers to filter network traffic, block unauthorized access, and protect against security threats.

8. Anterior Chamber of the Eye (ACL)

Description: The Anterior Chamber of the Eye (ACL) is the fluid-filled space between the cornea (front surface of the eye) and the iris (colored part of the eye). The ACL contains aqueous humor, a clear fluid that nourishes the cornea and maintains intraocular pressure, contributing to the overall health and optical properties of the eye.

9. Access Control Language (ACL)

Description: Access Control Language (ACL) is a programming language or syntax used to define and manage access control policies, permissions, and security rules within software applications, databases, or operating systems. ACLs specify which users, groups, or roles are granted or denied access to specific resources or operations based on predefined conditions or criteria.

10. Anterior Commissure of the Larynx (ACL)

Description: The Anterior Commissure of the Larynx (ACL) is a small structure located at the front of the larynx (voice box) where the thyroid cartilage and cricoid cartilage meet. The ACL plays a role in vocal cord tension and adjustment, contributing to the production of voice and phonation in speech and singing.
