Q. It is often difficult to estimate size at an early stage in a project when only a specification is available
  • (A) true
  • (B) false
  • (C) ---
  • (D) ---
πŸ’¬ Discuss
βœ… Correct Answer: (A) true

Explanation: function-point and object-point estimates are easier to produce than estimates of code size but are often still inaccurate.

Q. Which technique is applicable when other projects in the same analogy application domain have been completed?
  • (A) algorithmic cost modelling
  • (B) expert judgement
  • (C) estimation by analogy
  • (D) parkinson’s law
πŸ’¬ Discuss
βœ… Correct Answer: (C) estimation by analogy

Explanation: the cost of a new project is estimated by analogy with these completed projects.

Q. OSI stands for
  • (A) open system interconnection
  • (B) operating system interface
  • (C) optical service implementation
  • (D) open service internet
πŸ’¬ Discuss
βœ… Correct Answer: (A) open system interconnection

Explanation: osi is the abbreviation for open system interconnection. osi model provides a structured plan on how applications communicate over a network, which also helps us to have a structured plan for troubleshooting. it is recognized by the iso as the generalized model for computer network i.e. it can be modified to design any kind of computer network.

Q. TCP/IP model does not have layer but OSI model have this layer.
  • (A) session layer
  • (B) transport layer
  • (C) application layer
  • (D) network layer
πŸ’¬ Discuss
βœ… Correct Answer: (A) session layer

Explanation: in osi reference model, there are two layers which are not present in tcp/ip model. they are presentation and session layer. the functions of presentation and session layer in the osi model are handled by the transport layer itself in tcp/ip.

Q. According to the time estimates made by the PERT planners, the maximum time that would be needed to complete an activity is called as
  • (A) the most likely time estimate
  • (B) optimistic time estimate
  • (C) pessimistic time estimate
  • (D) expected time estimate
πŸ’¬ Discuss
βœ… Correct Answer: (C) pessimistic time estimate

Explanation: according to the time estimates made by the pert planners, the maximum time that would be needed to complete an activity is called the pessimistic time estimate. this estimate does not include possible effects of floods, earthquakes, etc.

Q. In a network, a critical path is the time- wise shortest path.
  • (A) true
  • (B) false
  • (C) ---
  • (D) ---
πŸ’¬ Discuss
βœ… Correct Answer: (B) false

Explanation: in a network, a critical path is the time-wise longest path. the critical path in the critical path method plays an essential role in scheduling and planning.

Q. The difference between the maximum time available and the actual time needed to perform an activity is known as
  • (A) free float
  • (B) independent float
  • (C) total float
  • (D) half float
πŸ’¬ Discuss
βœ… Correct Answer: (C) total float

Explanation: the difference between the maximum time available and the actual time needed to perform an activity is known as the total float. hence, the total float is the excess of the maximum available time throughout the time of the activity.

Q. A randomized algorithm uses random bits as input inorder to achieve a good performance over all possible choice of random bits.
  • (A) worst case
  • (B) best case
  • (C) average case
  • (D) none of the mentioned
πŸ’¬ Discuss
βœ… Correct Answer: (C) average case

Explanation: a randomized algorithm is an algorithm that employs a degree of randomness as a part of its logic using random bits as inputs and in hope of producing average case good performace.

Q. Which of the following are probalistic algorithms?
  • (A) las vegas algorithm
  • (B) monte carlo algorithm
  • (C) atlantic city algorithm
  • (D) all of the mentioned
πŸ’¬ Discuss
βœ… Correct Answer: (D) all of the mentioned

Explanation: monte carlo algorithms are very vast, but only probably correct. on thr other side, las vegas algorithms are always correct, but probably fast.
