That is correct. In general, HTML documents should be saved with the file extension ".html" or ".htm" to be recognized as HTML documents by web browsers.

HTML stands for HyperText Markup Language. It is a markup language used for creating web pages and other information that can be displayed in a web browser. HTML provides a structure for web pages by using a combination of tags, attributes, and text to define the layout, content, and functionality of a web page.

HTML allows you to add headings, paragraphs, images, videos, links, forms, and other elements to a web page. The language uses tags to specify how content should be displayed on a page. For example, the <h1> tag is used to create a heading, the <p> tag is used to create a paragraph, and the <img> tag is used to display an image.

Web browsers interpret the HTML code and render it into a web page that users can view and interact with. HTML is often used in combination with other web technologies such as Cascading Style Sheets (CSS) and JavaScript to create dynamic and interactive web pages.

The error message "unregistered authentication agent for Unix-process" typically occurs when you are trying to use an authentication agent (such as ssh-agent) without properly registering it with your system.

What is Authentication?

Authentication is the process of verifying the identity of a user, system, or device attempting to access a particular resource or service. The goal of authentication is to confirm that the person or entity claiming to be a particular user or system is indeed who they say they are.

Authentication typically involves the use of credentials, such as a username and password, a security token, or a biometric factor, which the user or system must provide to gain access. The system then compares the provided credentials to a database of authorized users or systems to confirm that the credentials are valid and match an existing user or system.

Authentication is a critical aspect of security and is used to protect sensitive information and resources from unauthorized access. It is often used in conjunction with other security measures, such as authorization, encryption, and auditing, to ensure that only authorized users or systems can access protected resources.

The error message "unregistered authentication agent for Unix process" typically occurs when an SSH agent is not running or has not been registered with the user's session. Here are some steps you can take to solve this issue:

1. Check if an SSH agent is running: Open a terminal and type the command "eval ssh-agent -s". If an agent is already running, this command will output some environment variables. If not, it will start a new agent and output the environment variables that you need to set.

2. Set the environment variables: If the ssh-agent command outputted some environment variables, copy and paste the output into the terminal. If not, use the output from the command in step 1.

3. Add your SSH key: Use the ssh-add command to add your SSH key to the agent. For example, type "ssh-add ~/.ssh/id_rsa" to add the default private key.

Therefore, If the above steps do not solve the issue, try restarting your computer or checking your SSH configuration files to ensure that they are correct.

By recording all transactions across the business network among participants. The aspect of blockchain that creates the system of record is its distributed ledger technology.

What Is Blockchain?

Blockchain is a decentralized digital ledger technology that allows multiple parties to securely and transparently record, store and verify transactions without the need for intermediaries, such as banks or other third-party institutions. In a blockchain network, transactions are grouped into blocks and then added to a chain of previous blocks, forming an immutable and transparent record of all transactions on the network.

Each block in a blockchain contains a cryptographic hash of the previous block, which creates a secure and tamper-proof link between all the blocks. This makes it virtually impossible to alter or manipulate any transactions on the network without detection, as any changes to a block would affect all subsequent blocks in the chain, causing the hash values to become invalid.

A distributed ledger is a database that is spread across a network of computers, where each computer on the network has a copy of the entire ledger. This means that every transaction that occurs on the network is recorded on multiple copies of the ledger, making it difficult to alter or tamper with the records.

In a blockchain network, transactions are grouped into blocks and then added to the chain of previous blocks, forming a chronological and immutable record of all transactions on the network. This decentralized and transparent system of record provides a high level of security, privacy, and reliability, and eliminates the need for intermediaries or central authorities to validate transactions.

Therefore,  the combination of the distributed ledger, consensus mechanism, and cryptographic hash functions used to link each block together creates a transparent, secure, and auditable system of record for all transactions on the network.
