The memory and battery are packed together in a single package. 31. It can be used as an indicator for the status of various signals or situations. 32. It is used for displaying alpha numeric characters. 33. It combines an LED and a photo-transistor in a single housing. 34. It is widely used in robotics to convert applied dc voltage to corresponding mechanical motion. 35. An electro mechanical device which acts as dynamic path selectors for signals and power. 36. It is a device for generating audio indications in embedded application. 37. In embedded application it is generally used as reset and start switch and pulse generator. 38. It refers to the control algorithm or the configuration settings that an embedded system developer dumps

    into the code memory of the embedded system.

    39. It is essential to ensure that the device is not operating at a voltage level where the device is not guaranteed to operate, during system power ON.

  • 40. It prevents the processor/controller from unexpected program execution behavior when the supply voltage to the processor/controller falls below a specified voltage.

    required.

    65. It is one of many subcategories of DRAM and can run at much higher clock speeds than conventional memory.

    66. It provides a programmable governing policy that allows software to determine which peripheral or device can interrupt the processor at any specific time by setting the appropriate bits in the interrupt controller

    registers.
