Who invented the first mechanical computer? in what year was it invented?.

Answer:

But before we get into all that, we should start at computing’s origins, because although electronic computers are relatively new, the need for computation is not.So each bead on the bottom row represents a single unit, in the next row they represent 10, the row above 100, and so on.But if we were to add 5 more after the first 3 we would run out of beads, so we would slide everything back to the left, slide one bead on the second row to the right, representing ten, and then add the final 2 beads on the bottom row for a total of 12.So if we were to add 1,251 we would just add 1 to the bottom row, 5 to the second row, 2 to the third row, and 1 to the fourth row - we don’t have to add in our head and the abacus stores the total for us.Over the next 4000 years, humans developed all sorts of clever computing devices, like the astrolabe, which enabled ships to calculate their latitude at sea.As early computer pioneer Charles Babbage said: “At each increase of knowledge, as well as on the contrivance of every new tool, human labour becomes abridged.”

To determine the resident subnet (network address) of the host IP address 200.10.15.82, we need to look at the subnet mask associated with that network.

An individual physical or logical address known as a network address is used to identify a network node or device on a computer or communication network. Any new device that requests access to the network or that is already a part of the network is given a network address, which is a numerical number or address.

The context-free grammar for Java variable declarations, limited to int and int[] data types, specifies the structure of valid variable declaration strings.

A context-free grammar consists of a set of production rules that define the structure of valid strings in a language. In this case, we need to define a grammar for Java variable declarations with int and int[] data types.

We can start by defining a non-terminal symbol "declaration" to represent a variable declaration. The production rule for "declaration" can be written as:

declaration -> type identifier ;

Here, "type" represents the data type of the variable, which can be either "int" or "int[]". "identifier" represents the name of the variable, which follows the specified naming convention. The semicolon (;) indicates the end of the declaration.

To define the data type, we can introduce a non-terminal symbol "type" with the following production rules:

type -> int

type -> int[]

Next, we need to define the structure of valid variable names. We can introduce a non-terminal symbol "identifier" with the following production rules:

identifier -> lowercase_letter suffix

suffix -> lowercase_letter suffix

suffix -> digit suffix

suffix -> ε

In the above rules, "lowercase_letter" represents any lowercase letter, and "digit" represents any digit (0-9). The "suffix" allows the variable name to consist of a combination of lowercase letters or digits. The last rule "suffix -> ε" indicates that the variable name can be just a single lowercase letter.

By defining these production rules and considering the naming conventions and data types, we can generate valid variable declaration strings in Java with int and int[] types.

Ethereum is the most popular blockchain for NFT development for a few reasons. First, it's the biggest and most well-known blockchain after Bitcoin.

Non-fungible tokens (NFTs) are types of digital assets that are provably unique, making them both collectible and useful for functions from establishing ownership of real-life assets to online gaming.

Characteristics:

One of the characteristics of currencies is fungibility, where each individual unit must be valued the same as—and interchangeable for—another unit. For instance, if you give your friend a 0.1 BTC from your wallet, and they give you a 0.1 BTC from theirs, no meaningful change in value has occurred.  NFTs, however, are blockchain-based assets (or, tokens) that are non-fungible, meaning they are one-of-a-kind.

Although NFTs were created and popularized on Ethereum, the first NFT concepts were built on Bitcoin. These were called “colored coins,” and they applied digital watermarks to coins that could be used to track off-chain assets (like gold).

Further, a platform called Counterparty was developed so people could create unique, Bitcoin-based tokens that could be used in blockchain-based gaming applications. The first of these games, Spells of Genesis, featured a deck-building game (a game where the main goal is to construct a deck of cards) and saw its first virtual “card” tokenized in March 2015.

The general agreement with flush is that invoking it indicates that any previously written bytes that have been buffered by the output stream implementation should be promptly sent to their appropriate destination.

Flushing the stream only ensures that previously written bytes are passed to the operating system for writing; it does not ensure that they are actually written to a physical device like a disc drive if the intended destination of this stream is an abstraction provided by the underlying operating system, such as a file.

The loss of the backup disk has affected several principles of information security, including confidentiality, integrity, and availability from the CIA triad and possession, utility, and authenticity from the Parkerian Hexad principles.

The CIA triad comprises three key principles: Confidentiality, Integrity, and Availability. They are vital in ensuring information security. The Parkerian Hexad extends the CIA triad to include three additional components: Possession, Utility, and Authenticity. They help to expand the CIA triad by addressing other aspects of information security in different environments.The scenario described in the situation has affected both the CIA triad principles and Parkerian Hexad principles in the following ways:Confidentiality is affected as personal and payment information for their customers is on the backup disk that has been lost.

The medical office must ensure that customer data remains confidential and not released to unauthorized individuals. There is a risk of customers' data getting exposed to unintended persons who may use it for malicious purposes. The principle of confidentiality involves maintaining the privacy of data, and it is one of the CIA triad principles that are essential for maintaining the security of information.Integrity is also affected because the backup disk was encrypted, but the information is lost. The medical office must ensure that the data is consistent and accurate. In the context of information security, integrity refers to ensuring the data is complete, accurate, and unchanged.

Loss of data may lead to inaccurate information being used, causing harm to customers or the organization itself. The principle of integrity is essential in maintaining the accuracy of information and ensuring the data is trustworthy.Availability is also affected because the medical office has lost critical information about their customers. The backup disk was stored off-site in a secure location to prevent the data from being lost or damaged. However, the carrier lost the disk, and now the medical office has to find ways to recover the lost data. Availability is one of the CIA triad principles that ensure information is available when required.

When information is lost, it may cause delays, leading to loss of revenue and reputation.The Parkerian Hexad principles that have been affected include Possession, Utility, and Authenticity. Possession is the assurance that an authorized individual or system has control over the information. In this scenario, the loss of the backup disk means that possession of the information is no longer within the medical office's control. This puts the data at risk of being accessed by unauthorized individuals.Utility refers to ensuring that the information is useful for authorized users.

The medical office stored the backup disk in an off-site location to ensure that the data is available when required. However, the loss of the backup disk has caused the medical office to lose access to critical customer information, leading to a reduction in the data's utility.Authenticity is the principle of ensuring that the data is genuine and can be trusted. The medical office had encrypted the backup disk to prevent unauthorized access to customer information. However, the loss of the backup disk means that the authenticity of the data cannot be verified, leading to a breach of trust and loss of reputation.
