Answer: a) Single-bit errors: It affects only one bit in a symbol.
Burst errors: It affects to several sequential bits in a given
symbol
b) 10000 bits.
c) When the most typical error is a single bit error.
Explanation: a) It is explained in the answer.
b) If data is being transmitted at 100 Mbps, this means that in 1 second, 100x 10e6 bits are transmitted, and that one single bit lasts for 10e-8 sec.
So, if the noise event that causes the burst error lasts 0.1 msec, this means 10e-4 sec.
Number of bits in error= 10e-4/10e-8= 10e4 bits= 10000 bits.
c) If the error is in a single bit in a symbol, this means that if the right number of 1s is even, a single error will change this number to an odd number , and the error could be easily detected.
Computer simulation is just like training for example before pilot fly plane they got training from computer simulation it's just like video lecture
Answer:
b. When an array is created, the number of elements must be placed in square brackets following the type of element being stored.
Explanation:
In Java an uninitialized array contains null values. Thus statement c is true as well.
Also generally for initializing and displaying array elements a for loop is used. Hence statement d is also correct.
In Java syntax for declaring an array is as follows:
Array declaration:
type [] array_name ;
Array instantiation(memory allocation):
type [] array_name = new array_name [size of array];
From the above it can be seen that the statement a is true and statement b is false as number of elements in array are not mentioned after the type.
Hence the correct answer is b.
