Geometry Units of Measurement

Length: units of measurement include meters (m), centimeters (cm), millimeters (mm), kilometers (km), inches (in), feet (ft), yards (yd)
Angle: units of measurement include degrees (°), radians (rad)
Area: units of measurement include square meters (m²), square centimeters (cm²), square millimeters (mm²), square inches (in²), square feet (ft²), square yards (yd²)
Volume: units of measurement include cubic meters (m³), cubic centimeters (cm³), cubic millimeters (mm³), cubic inches (in³), cubic feet (ft³), cubic yards (yd³)

Length:
- 1 meter = 100 centimeters = 1000 millimeters
- 1 kilometer = 1000 meters
- 1 inch = 2.54 centimeters
- 1 foot = 12 inches
- 1 yard = 3 feet
Angle:
- 1 degree = π/180 radians
- 1 radian = 180/π degrees
Area:
- 1 square meter = 10000 square centimeters
- 1 square kilometer = 1000000 square meters
- 1 square inch = 6.4516 square centimeters
- 1 square foot = 144 square inches
- 1 square yard = 9 square feet
Volume:
- 1 cubic meter = 1000 cubic centimeters
- 1 cubic kilometer = 1000000 cubic meters
- 1 cubic inch = 16.387 cubic centimeters
- 1 cubic foot = 1728 cubic inches
- 1 cubic yard = 27 cubic feet

Rulers: used to measure length and distance
Protractors: used to measure angles
Calipers: used to measure precise distances and lengths
Measuring tapes: used to measure longer distances and lengths
Geometry software: used to calculate and measure geometric shapes and figures

A set of integrated hardware and software components that work together to perform a specific task or set of tasks.
Consists of input devices (e.g. keyboard, mouse), processing unit (CPU), storage devices (e.g. hard drive, RAM), and output devices (e.g. monitor, printer).
Can be classified into desktop systems, laptop systems, mobile systems, and embedded systems.

A collection of organized data that is stored in a way that allows for efficient retrieval and manipulation.
Consists of database management system (DBMS), database schema, data storage, and data retrieval and manipulation tools.
Types of database systems include relational database management systems (RDBMS), object-oriented database management systems (OODBMS), and NoSQL database systems.

A set of software that manages computer hardware resources and provides common services to computer programs.
Functions include process management, memory management, file system management, input/output (I/O) management, and security management.
Types of operating systems include single-user, single-tasking systems, multi-user, single-tasking systems, multi-user, multi-tasking systems, and real-time operating systems.

A set of integrated components that collect, store, and provide access to information.
Consists of hardware components (e.g. computers, servers), software components (e.g. applications, operating systems), data components (e.g. databases, files), network components (e.g. internet, intranet), and human components (e.g. users, administrators).
Types of information systems include transaction processing systems, management information systems, decision support systems, and expert systems.

A complex system of nerve cells (neurons) that transmit and process information in the body.
Consists of central nervous system (CNS): brain and spinal cord, and peripheral nervous system (PNS): nerves and ganglia outside the CNS.
Functions include control and coordination of body functions, sensory input and perception, motor control and movement, and regulation of body functions (e.g. heart rate, blood pressure).
Divided into somatic nervous system: controls voluntary movements, and autonomic nervous system: controls involuntary movements (e.g. heart rate, digestion).
