IBPS Exam : Computer Awareness Questions Bank -2

Here is the important expected Computer Awareness Questions Bank -2 for IBPS Bank PO/SO/Clerk, RRB, RBI Officer and Assistant Exam. These Computer Network Questions and Answers are must for every aspirants.

Q.31. Topologically fully connected networks have the highest performance and the highest cost among the possible. 

Q.32. In full-duplex transmission mode devices can transmit and receive simultaneously. 

Q.33. For bit-rate to be three times the baud rate we need at least 8 constellations. 

Q.34. Physical Layer deals with the physical and electrical specifications. 

Q.35. The term point-to-point indicates the dedicated links between two nodes. 

Q.36. Bus topology is the simplest and cheapest topology to implement in small networks. 

Q.37. Full-Duplex transmission mode can be characterized simply as "two way simultaneous transmission/reception". 

Q.38. Performance of a network is usually measured by bits per second 

Q.39. Switching/Routing is the job of Network Layer. 

Q.40. Sliding Window line discipline where only some of the enquiries are acknowledged is more efficient then Stop-and-Wait. 

Q.41. 10BaseT can have a maximum segment length of 100 meters. 

Q.42. All NICs are manufactured having unique Hardware Address. 

Q.43. Physical addressing, error control and access (to media) control are managed by the Data Link layer. 

Q.44. An advantage of 10BaseT over 10Base2 is that 10Base2 is maintained easier than 10Base2. 

Q.45. ‗Preamble‘ field at the beginning of an ethernet frame is used for synchronization. 

Q.46. Bridges must have the following layers; Physical Layer 2 Data Link Layer. 

Q.47. ‗Time To Live‘ field in an IP packet determines the number of hops (routers) it passes through before it is discarded. 

Q.48. A host running in an IP-network on the ethernet must be assigned these three numbers properly in order for the networking software to operate correctly; IP address, 2. Netmask, 3. Gateway address. 

Q.49. ARP is used on IEEE-802.3 networks in order to obtain ethernet addresses using the IP addresses. 

Q.50. The field named as ‗Window Size‘ in a TCP segment header indicates the sliding window size. 

Q.51. Standard TCP services use some standard TSAP numbers known as well known ports numbers. 

Q.52. TCP is a connection oriented protocol while UDP is not. 

Q.53. The three problems which limit a communication line are attenuation, distortion and noise. 

Q.54. In order for a 2400 baud modem to achieve 9.6 kbps the constellation diagram must have at least 16 distinct points. 

Q.55. The filter with a bandwidth of 300-3400 Hz at the end office for an ordinary voice phone line is removed for DSL operation. 

Q.56. An ADSL modem and a splitter are the required equipment residing at the customer‘s premises for the ADSL system. 

Q.57. Three of the BlueTooth profiles are Service Discovery, Serial Port, Cordless Telephony. 

Q.58. In piconets of BlueTooth, Frequency Hopping Spread Spectrum technique is used with 1600 

Q.59. hops/sec and hop sequence is dictated by the master. 

Q.60. Pseudoternary encoding technique is used on T and S interfaces of ISDN system in order to maintain synchronization during the long sequences of zeros
