1. What is data structure ? Answer: A data structure is a way of organizing data that considers not only the items stored, but also their relationship to each other. Advance knowledge about the relationship between data items allows designing of efficient algorithms for the manipulation of data. 2. List out the areas in which data structures are applied extensively? Answer: Compiler Design, Operating System, Database Management System, Statistical analysis package, Numerical Analysis, Graphics, Artificial Intelligence, Simulation 3. If you are using C language to implement the heterogeneous linked list, what pointer type will you use? Answer: The heterogeneous linked list contains different data types in its nodes and we need a link, pointer to connect them. It is not possible to use ordinary pointers for this. So we go for void pointer. Void pointer is capable of storing pointer to any type as it is a generic pointer type. 4. What is the data structures used to perform...

1. Why is Bluetooth 2.0 better ? Answer: The main features of Bluetooth Core Specification Version 2.0 + EDR are: •  3 times faster transmission speed (up to 10 times in certain cases) •  Lower power consumption through reduced duty cycle •  Simplification of multi-link scenarios due to more available bandwidth •  Backwards compatible to earlier versions •  Further improved BER (Bit Error Rate) performance 2. Name few applications of Bluetooth? Answer: *  Wireless control of and communication between a cell phone and a hands free headset or car kit. This is the most popular use. *  Wireless networking between PCs in a confined space and where little bandwidth is required. *  Wireless communications with PC input devices such as mouses and keyboards and output devices such as printers. *  Transfer of files between devices via OBEX. *  Transfer of contact details, calendar appointments, and reminders between d...
