Answer:
D. There were 176,400 samples of the orchestra music taken every second.
Explanation:
In Signal processing, whenever we convert a analog signal into Digital signal. We makes the sample of that audio signal. These samples are calculated using Nyquist Theorem. These are measured in the unit of samples per second which is called sampling rate. According to the Nyquist theorem, for better performance in digital signal, sampling rate should be double of the actual frequency of the signal in analog.
In given case 176,400 Hz is the sampling rate of the digital audio of the orchestra which means 176,400 samples per second.
Microprocessor I think is what the PLC uses for there processor.
Answer: Can you rephrase the question
Explanation:
Answer:
1. 10 bits
2. 1022 Hosts / Subnet
Explanation:
Given Network ID is 172.20.0.0
Class B network contains :
Network ID = 16 bits
Host ID = 16 bits
For subnetting always host id bits are used.
Number of subnets required = 50. Subnets are always in power of two. Nearest power of two to 50 is 26 = 64.
So, to create subnet we require 6 bits from host id and 64 subnets can be created with those 6 bits.
1)
Number of host bits needed for new subnets for network information = 6 bits.
Therefore, New network information contains :
Network ID of subnet = 16 + 6 = 22 bits
Host ID = 16- 6 = 10 bits.
2)
Subnets required = 50
Subnets created with 6 bits = 64.
Number of subnets unused for future expansion = 64 - 50 = 14 subnets.
Host ID part contains 10 bits. Therefore, Total number of Hosts /Subnet = 210 = 1024 Hosts.
Number of usable hosts per subnet = 1024 -2 = 1022 Hosts / Subnet.
The PHP function that is executed is a connection to a database that cannot be made is the die() function.
An error is an undesirable programming outcome. The mistake is a subset of the error. Error management is a vital component of any website or programme.
Error handling is a mechanism for identifying errors that a programme makes and taking appropriate corrective action. This can be done by utilising die() method.
When a programming problem occurs, the software will halt further code execution and display the appropriate error message to the user. The die() function displays a message and terminates the running of the programme.
The connect() function in PHP is one that is used to establish a connection to a database.
The end() method in PHP is used to locate the final element of the specified array. The end() function updates an array's internal pointer to refer to the final element and returns that element's value.
The isset() function examines whether a variable is set, which implies that it has to be declared and is not NULL. If the variable is present and not NULL, this function will return true; otherwise, it will return false.
