Answer:
1. ‘cout’ was not declared in this scope.
2. ‘cin’ was not declared in this scope.
3. lvalue required as left operand of assignment.
Explanation:
The code gives the error cout and cin was not declare. This error means, we not include the library where they define.
cout and cin is the input/output instruction and they include in the library iostream file.
the last error is lvalue required as left operand of assignment.
lvalue means the assignable value, we actually do the wrong assignment.
number1 + number2 = sum;
here, sum is is the assignment variable. so, it must be in the right side of the '=' operator.
sum = number1 + number2 ;
Now, the above is correct. the value number1 plus number2 is assign to sum.
Answer:
There are no additional components that can be added to the IPv4 protocol to improve its utility
Explanation:
The IPv4 protocol was developed in 1983 and is still the most widely used version worldwide. It consists of a 32-bit binary number that is normally represented in decimal notation, with four digits separated by dots that take values between 0 and 255.
This system limits the IPv4 protocol to 4,000 million different addresses, a figure that in the eighties seemed sufficient but that in practice has been scarce due to the revolution of mobile devices and the impending development of the Internet of Things ( IoT) that will trigger the number of devices connected to the network.
So, there are no additional components that can be added to the IPv4 protocol to improve its utility, since the world is running out of IPv4 addresses and is being replaced by IPv6.
Hope this helps!
Answer:
Yes, the purpose of a database in a way is to stop people from using spreadsheets but, it is also so much more.
Explanation:
<u>Databases</u> are a vastly improved form of a spreadsheet. They allow Computer Scientists to automatize a company's information. Giving them the ability to instantly add, retrieve, and modify specific information within a database of hundreds or even thousands of entries. All this with little or no human input. Thus saving a company time and money as opposed to using a regular spreadsheet which requires manual input from an employee.

= 10
B) The smallest number of records that could appear in one bin
= 1
C) The largest number of records that cab appear in one bin
= 10
d) smallest number
= 1
e) With frequency = 20. the largest number of records that could appear in one bin with equal width discretization (10 bins)
= 20
f ) with equal height discretization
= 10
