If end to end delay is given by dend-end = N(dproc + dtrans + dprop) is a non congested network. The number of routers between source and destination is?(a) N/2(b) N(c) N-1(d) 2N |
|
Answer» Right option is (c) N-1 The best I can explain: In the equation N (dproc + dtrans + dprop), N is the number of checkpoints/stops that the packet makes as it reaches the destination. The stops are made at each router and the final destination node. Now, since N = number of routers + final node, then number of routers = N – final node. As we know, there is only 1 final node in a path, thus, number of routers = N – 1. Suppose, There is a path A->R1->R2->B for a packet where A is the source node, B is the final node and R1 and R2 are routers. The total delay would be given by N (dproc + dtrans + dprop) where N = 3, since the packet would stop at R1, R2 and B. The number of routers here are 2, and (N – 1) is also 2. |

When you try to execute a program, there are chances of errors at various stages, Mention the types of errors and explain. |
|
Answer» 1) syntax error : eg : 5=x 2) Logic error. If the programmer makes any logical mistakes, it is known as logical error. Eg: To find the sum of values A and B and store it in a variable C you have to write C=A+B. Instead of this if you write C=A*B, it is called logic error. 3) Runtime error : An error occured at run time due to inappropriate data. Eg: To calculate A/B a person gives zero to B. There is an error called division by zero error during run time. |

Briefly explain the characteristic of an algorithm. |
|
Answer» The following are the characteristics of an algorithm 1. It must starts with ‘start’ statement and ends with ‘stop’ statement. 2. it should contains instructions to accept input and these are processed by the subsequent instructions. 3. Each and every instruction should be precise and must be clear. The instructions must be possible to carry out, for example consider the examples the instruction “Go to market” is precise and possible to carried out but the instruction “Go to hell” is also precise and can not be carried out. 4. Each instruction must be carried out in finite time by a person with paper and pencil. 5. The number of repetition of instructions must be finite. 6. The desired results must be obtained after the algorithm ends. |
