describe 3 differences between the checksum and check digit:

Answers

Answer 1

Answer:

A check digit, also known as a checksum character, is the number located on the far right side of a bar code. The purpose of a check digit is to verify that the information on the barcode has been entered correctly.

Answer 2

A check digit, even comprehended as a checksum character, stands for the number found on the far right side of a bar code. The intention of a check digit exists to confirm that the information on the barcode contains been documented accurately.

What are the differences between the checksum and check digit?

A checksum in public can be any size, although generally, they exist some suitable number of bits for computation, such as 32. The more extensive the checksum, the wider the range of errors it can capture. For instance, the checksum utilized for credit card numbers will notice changed digits that exist after each other, but not reversed digits that exist split by a single digit.

All cryptographic hashes (like MD5, SHA, etc.) can be utilized as checksums, but not all checksums exist cryptographic. CRC-type checksums aren’t cryptographic, but they’re extremely quick to calculate, and so they exist generally utilized for things like hard drive checksums where you don’t require the cryptographic functionality, but you accomplish want to notice an extensive range of probable errors.

Hacking is a process to exploit a computer network system or a private network within a computer. Simply put, unauthorised access to or control of a computer network security system for unauthorised purposes.

To better explain hacking, we must first understand hackers. It’s easy to a Hacking assume that they are intelligent and highly skilled with computers.

In fact, breaking security systems requires more intelligence and expertise than actually creating them. There are no hard and fast rules that can classify hackers into neat categories. However, in common computer terminology, these are called white hats, black hats, and gray hats. White hat experts audit their own security systems to make them more resistant to hacking.

∧-∧ But Read the Explanation to Make Sure ∧-∧

Answer/Explanation:

These algorithms have undergone extensive security analysis and are continually tested to ensure that they provide adequate security. Cryptographic algorithms will usually use cryptographic keys and when these algorithms need to be strengthened, it can often be done by using larger keys.

Encryption uses complex algorithms to scramble data and decrypts the same data using a key provided by the message sender. Encryption ensures that information stays private and confidential, whether it's being stored or in transit. Any unauthorized access to the data will only see a chaotic array of bytes.

The strength of an algorithm, is defined both in terms of it's key size, as well as it's resistance to cryptanalytic attacks. We say an algorithm is broken if there exists an attack better than brute force. So, with AES and a 128-bit key, AES is considered "secure" if there is no attack that less than 2^128 work.

There seems to be an emerging requirement to specify cryptographic strength objectively  rather than subjectively with adjectival descriptors such as weak, good or strong. It is expected  that U.S. Government (USG) and industry will soon require specific quantitative data to define the  point at which a cryptographic technology or product will satisfy user requirements.

Knowing that these 2 Choices Don't really look Right...

Because it our job = Wrong

Because encryption algorithm are always weak = Wrong

So It leads us to these...

To Prevent all Decryption = ?

To protect online Information = ?

But Base on the Information below:

Encryption can help protect data you send, receive, and store, using a device. That can include text messages stored on your smartphone, running logs saved on your fitness watch, and banking information sent through your online account.

Encryption is the process that scrambles readable text so it can only be read by the person who has the secret code, or decryption key. It helps provide data security for sensitive information.

Vast amounts of personal information are managed online and stored in the cloud or on servers with an ongoing connection to the web. It’s nearly impossible to do business of any kind without your personal data ending up in an organization’s networked computer system, which is why it’s important to know how to help keep that data private.

Some employers might be tempted to fire an employee using an impersonal method ⁠— like a phone call, email, or text ⁠— just to avoid that discomfort. But that is a very bad idea. We strongly recommend that employers should only fire staff during a face-to-face termination meeting.
