Answer:

The correct answer to the following question will be "True".

Explanation:

SCADA is a hardware and software elements program that permits industrial enterprises to:

  • Agricultural processes are regulated locally or globally.
  • The human-machine interaction program specifically interfaces with equipment such as cameras, switches, generators, motors and much more.
  • Track, store, and process the data in real-time.

Therefore, the given statement is true.

Bas_tet [7]

Answer:

Explanation:

Data security is the process of protecting your most critical business assets (your data) against unauthorized or unwanted use.

This not only involves deploying the right data security products, but also combining people and processes with the technology you choose to protect data throughout its lifecycle. Enterprise data protection is a team sport.

Best practices for effective data security include taking a risk-based approach to protecting data, using a unified platform that integrates data security information across your entire enterprise and ensuring scalability across environments of any size across public cloud, on-premises and hybrid cloud deployments.

Ip address 10.10.20.0 255.255.255.224 how many host ip addresses are available in each subnet using this subnet mask?
Maksim231197 [3]
224 = 128 + 64 + 32, so that would mean each network could have 32 nodes. Subtract 2 for the network address and the multicast address, you would have 30 HOST addresses available.

Use the set A = { a, b, c ,d } to answer the following questions.
Gekata [30.6K]

Answer:

What is the cardinality of A? 4

What is the power set of ℘(A)?

P(A) = {Ф, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,b,d}, {b,c,d}, {a,c,d},{a,b,c,d}}

What is the cardinality of the power set? 16

What is the power set of A = { }? => {{ }} or {Ф

Explanation:

Given set is:

A = {a,b,c,d}

<u>What is the cardinality of A?</u>

The cardinality of set is the number of elements in the set

Since, set A has four members the cardinality is 4.

i.e.

n(A) = 4

<u>What is the power set of ℘(A)? </u>

The power set of a set consists of all the subsets of a set.

So the power set of A will consist of all subsets of A.

The power set is:

P(A) = {Ф, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,b,d}, {b,c,d}, {a,c,d},{a,b,c,d}}

<u>What is the cardinality of the power set?</u>

The number of subsets of a set is the cardinality of power set.

As A is 4 members,

Cardinality of Power set of A = 2^4 = 16

<u>What is the power set of A = { }</u>

As A is an empty set, its power set will have only one element (Ф) as member

P(A) = {{ }} or {Ф}

Hence,

What is the cardinality of A? 4

What is the power set of ℘(A)? P(A) = {Ф, {a}, {b}, {c}, {d}, {a,b}, {a,c}, {a,d}, {b,c}, {b,d}, {c,d}, {a,b,c}, {a,b,d}, {b,c,d}, {a,c,d},{a,b,c,d}}

What is the cardinality of the power set? 16

What is the power set of A = { }? => {{ }} or {Ф
