- Question
What signals are transferred in GPRS?
- 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

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
Correct Answer: The World Wide Web Consortium
Correct Answer: 3
Explanation:
HTML Tag is used to make a text italic.
Correct Answer: 1 An injector is a service locator 2 It is used to retrieve object instances as defined by provider, instantiate types, invoke methods and load modules 3 There is a single injector per Angular application, it helps to look up an object instance by its name
Correct Answer: A child selector is used when you want to match an element that is the child of another specific element The parent and child selectors are separated by spaces The following selector locates an unordered list element within a paragraph element and makes a text within that element bold p > ul {font-weight: bold;}
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
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
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
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
Correct Answer: Linked list
Explanation:
Linked list is the efficient datastructure in tree construction
