The two basic kinds of cells are prokaryotic (bacteria) and eukaryotic cells, a eukaryotic cell has a nucleus and organelles, but prokaryotic don't have a nucleus and have ribosomes instead of organelles.
SIGINT stands for Signals Intelligence. The SIGINT is intelligence gathering by interception of signals, whether between people, involving electronic signals not directly used in communication or a combination of the two. As a means of collecting intelligence, SIGINT is a subset of intelligence collection management.
The two kinds of branches that extend from the cell body of a neuron are dendrites and axons. Dendrites receive signals from other neurons and transmit them towards the cell body, while axons transmit signals away from the cell body to other neurons or target cells.
Humans have two different kinds of nerves—sensory (afferent) nerves and motor (efferent) nerves—to facilitate communication between the body and the brain. Sensory nerves transmit signals from sensory organs and tissues to the brain, allowing for the perception of stimuli, while motor nerves carry signals from the brain to muscles and glands, enabling movement and responses. This dual system allows for coordinated actions and reactions to the environment, essential for survival and interaction.
The two most recognizable types of electron tubes are vacuum tubes and cathode ray tubes. Vacuum tubes are electronic devices that control electrical signals, while cathode ray tubes are used in older television and computer monitors to display images.

Linear and rotational
In biology, a signal is a molecule that carries information within cells or between cells. Two kinds of signals that control the cell cycle are stimulatory signals, which promote progression through the cell cycle, and inhibitory signals, which halt or slow down the cell cycle.
This is known as a communication cycle.

Two basic kinds of lenses are converging lenses, which focus light rays to a point, and diverging lenses, which spread out light rays. Converging lenses are thick in the center and thin at the edges, while diverging lenses are thin in the center and thick at the edges.
