- 3. How is 3G different from 2G? Discuss
Correct Answer: - Packet data speed is higher in 3G, and it is up to 384 KBPS - Voice and sms speed is also 384 KBPS in 3G - 2G utilizes different switching techniques for voice and data, where as 3G uses single switching, irrespective of data - 3G has at least 2MB of data link of a mobile, where in 2G the data rate is in KBPS - 3G has WiMAX facility for faster VOIP and internet - 2G uses GSM TDMA technology with narrowband 200Khz - 3G uses CDMA technology with broadband 5Mhz, with same frequency carrier and time
- 4. What signals are transferred in GPRS? Discuss
Correct Answer: - GPRS uses 25 generation of GSM signals - The radio interface is the same that of GSM - GPRS uses 900 / 1800 Mhz, frequency band and GMSK modulation - The bit rates are EGPRS, similar to EDGE - Separate hardware and ports need to be added and availed
- 5. What gross data rate does GPRS provide? Discuss
Correct Answer: - GPRS provide gross data rate of 2280 KBPS / time slot - Voice uses only 13KBPS/ time slot and the rest is consumed by Error Correction Code - Error connection code is utilized for detecting and correcting the transmission errors - As voice is compressed, the usage of Error connection code is mandatory
- 6. What is the maximum data rate supported by a GSM system? Discuss
Correct Answer: - The maximum data rate supported by a GSM system is 96 kbps - However there are extensions to GSM standard to improve throughput - GPRS is one of the extended GSM service - The extended standards of GSM allows theoretical data rates on the order of 114 Kbit/s, but with throughput closer to 40Kbit/s in practice
- 7. What is IMS (DB/DC)? Discuss
Correct Answer: IMS (Information Management System) is IBMs hierarchical database management system It has mainly two components: IMS DB and IMS DC (Also know as IMS TM) IMS DB - IMS/Database Manager as the name implies manages the IMS databases It is used for physical storage creation and management and data retrieval IMS DC / IMS TM - IMS/Data Communications or IMS/Transaction Manager handles online transaction processing system
- 8. What are SD37, SB37, SE37 abends? Discuss
Correct Answer: All indicate dataset out of space SD37 - no secondary allocation was specified SB37 - end of vol and no further volumes specified SE37 - Max of 16 extents already allocated
- 9. In tree construction which is the suitable efficient data structure?
Options- A. Array
- B. Linked list
- C. Stack
- D. Queue Discuss
Correct Answer: Linked list
Explanation:
Linked list is the efficient datastructure in tree construction
- 10. List out the areas in which data structures are applied extensively? Discuss
