7.1 Write statements that create the following arrays: A 100-element int array referenced by the variable employeeNumbers. final
maria [59]

Answer:

A. int [ ] numbers = new int[employeeNumbers];

B. double[ ] numbers = new double[payRates];

C. float[ ] miles = new float[14];

D. char[ ] letters = new char[1000];

7.2 Size of array cannot be negative

Size of array should be a positive integer and not decimal.

7.4 The size declarator is used in a definition of an array to indicate the number of elements the array will have. A subscript is used to access a specific element in an array.

7.5 subscript to be out-of-bound means the specified integer is not within the range of the length of the array.

Explanation:

The question has answer given for some. I guess the explanation is what is needed.

A. The general format of creating an array is:

data type[] arrayRefVar=new datatype[size];

In this case, the datatype is int, arrayRefVar is numbers, size is employeeNumbers. The size was already initialised to 100 (employeeNumber).

B. A wrong datatype was used.

double[ ] numbers = new double[payRates];

would create an array of size 25 which is the payRates with types double.

C. The array was re-written using the general format of creating an array is:

data type[] arrayRefVar=new datatype[size];

D. The array was correctly defined.

PtichkaEL [24]

Answer:

RS422-A or RS-485

Explanation:

Mode Name: RS422-A

Well, this is the electrical interface. The microprocessor covers the logics to electrical signals, and these electrical signals are then transmitted over a long distance, which is less than 4000 feet through RS422-A. And this is a half-duplex mode with the multidrop receiver and one transmitter at a time, in master-slave format. A receiver is a slave and the transmitter is a master. And there can only be one transmitter at a time. Here, a PC collects the videos from all cameras, through a unified system, and this PC is connected to numerous receivers which are the Screens. Parallel transmission cannot be done over a single line, and it's noisy as well, and hence we stick to serial mode. and here half-duplex as one at a time need to deliver, and not both. Hence, RS422-A is the first mode. which is a half-duplex serial transmission mode.

Reason 1:

It's noiseless

Reason 2:

The number of receivers can be as high as 10.

As the second alternative option:

Mode Name: RS-485

This is even better and allows receivers as high in number as 32, and hence is better than RS-422A. The maximum distance allowed is around 4000 feet, and the rest is the same as RS-422A. it also supports half-duplex.

Reason 1: It's less noisy and even better than RS422-A

Reason 2: number of receivers, and as high as 32 are allowed.

Remember, however, Ethernet is a low distance network, though it also supports collision detection, and multiple access/ carrier detection or CSMA/CD. However, for this question requirement RS-422A and RS-485 network interface will work fine. In the case of ethernet, we have an Ethernet Interface card, which works as an Ethernet network interface. However, Ethernet is a short distance, and will not work here.
