An attribute whose value uniquely identifies an object is called a(n) _______.

1 answer:

6 0

This is called a key attribute!

There are different types of key attributes!

Primary key is the key that is actually chosen, for example a social security number.

There is also a unique key, say our finger prints! they also uniquely identify humans, but usually we prefer to use social security number when we list people (a unique key could be a primary key if we chose so)

We could also identify people by their social security number and a name, but this is unnecessary, as social security number already gives a full identification. Such a reduntant key is called super key.

A restaurant recorded the ages of customers on two separate days. You are going to write a program to find the minimum age of a

Liono4ka [1.6K]

According to your code, you are setting the first element of the customerAges list as your baseline age. You then use a for loop to check each item in the list to see if it is less than your minimum variable. Then you assign the item to the minimum.

The missing line of code is b, if minimum > item:

When you use a while loop to compute the product of several values, you should initialize the variables holding the product to _

Allushta [10]

Answer:

b.1

Explanation:

When we are using while loop to compute the product of several values we need to initialize the value holding the product to 1 because when we multiply something with 1 it will give the same number.

If we initialize it with 0 the product will come out to be 0 because anything multiplied by 0 is 0.

we cannot initialize it with NULL because it is not a pointer.

We need to initialize the number since it contains garbage values so it will give product with that value.

Pavlova-9 [17]

Evaluation, formatting, expanding/decoding, distillation/reduction, and assessment are examples of <u>fog</u> computing operations.

The correct option is C.

<h3>What is computing operations?</h3>

An action that is taken in computing to complete a certain task is referred to as an operation. The five fundamental categories of computer operations are input, processing, output, storing, and control. The five major functional components of a computer system each carry out one or more computer activities.

<h3>What are the basic computing operations?</h3>

Arithmetic and logical operations are the two primary sorts of work that CPUs carry out. In contrast to logical operations, which compare two numbers, arithmetic operations involve basic math concepts like addition and subtraction.

<h3>What is fog computing operations?</h3>

Both 5G and fog computing

Fog computing refers to a type of computer architecture in which a network of nodes continuously collects data from Internet of Things (IoT) devices. These nodes have millisecond response times and process data in real-time as it comes in. Every so often, the nodes communicate to the cloud analytical summary data.
