The short message service center (SMSC) is the portion of a mobile phone network that handles text message operations. It is responsible for receiving, storing, routing and forwarding SMS messages from mobile handsets. It is also called a short message service-service center (SMS-SC). All text or SMS messages involve one or more SMSCs. In a typical message flow, the handset sends the message to the SMSC, which responds with a message indicating it accepted the SMS.

An arithmetic logic unit (ALU) is a part of a central processing unit (CPU) that carries out arithmetic and logic operations. The ALU takes the input operands and an instruction and outputs the result. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU). Some processors contain more than one AU -- for example, one for fixed-point operations and another for floating-point operations.

A capacitor is a passive electronic component that stores electrical charge. The amount of energy that a capacitor can store is called capacitance. Capacitance is measured in farads. Capacitors are used in almost every electronic circuit. Most capacitors are rated in microfarads, nanofarads or picofarads. Capacitors can store small amounts of electrical energy. In this way, they can be thought of as working like a rechargeable battery.

All network-connected devices have standardized ports with assigned numbers. These numbers are reserved for certain protocols and their associated functions. HTTP messages, for example, go to port 80 -- one of the most commonly used ports.

Brain-computer interface (BCI) is a device that translates signals in the brain to control some external activity. For example, they might control a cursor or a prosthetic limb. They might also be called a brain-machine interface. BCI is currently being researched and is targeted at people with disabilities as an adaptive technology. In BCI, signals in a brain are read directly, without the involvement of the muscular-skeletal system.
