Physical objects that are embedded with sensors, processing ability, software, and other

technologies that connect and exchange data with other devices and systems of the Internet or

other communications networks.

Medium Access Control (MAC)

The layer that controls the hardware responsible for interaction with the wired, optical, or wireless

transmission medium.

Microcontroller Unit (MCU)

A small computer on a single metal-oxide-semiconductor integrated circuit chip.

Memory Protection Unit (MPU)

A computer hardware unit that provides memory protection and is usually implemented as part of

the CPU.

One Time Programmable (OTP) memory

A type of non-volatile memory that permits data to be written to memory only once.

Orthogonal Frequency Division Multiple Access (OFDMA)

A multiple access mechanism for shared medium networks based on Orthogonal Frequency Division

Multiplexing (OFDM) achieved by assigning subsets of channel sub-carriers to individual users. This

allows simultaneous on-air frame transmissions to or from multiple users.

Packet Traffic Arbitration (PTA)

A collaborative coexistence mechanism for collocated wireless protocols.

Pairwise Master Key (PMK)

An intermediate encryption key used by the 4-way handshake to generate the temporal keys needed

for data stream encryption."

Pairwise Transient Key (PTK)

A key that protects unicast data between the client station and access point.

Peer-to-peer (P2P)

A distributed application architecture that partitions tasks or workloads between peers.

Physical (PHY)

The first and lowest layer of computer networking. This layer is closely associated with the physical

connection between devices.

Power Management Unit (PMU)

A microcontroller that controls power functions of digital platforms.

Pre-shared Key (PSK)

A password authentication method, a string of text, expected before a username and password to

establish a secured connection. Also known as a "shared secret".

Printed Circuit Board (PCB)

A board that connects electronic components.
