Computer (Part-6)

The delivery of computing services such as data storage, servers, and databases over the internet is known as cloud computing.

• This means you can access and use these resources on demand from a provider's data centers, without needing to own and maintain the physical infrastructure yourself.
• It offers benefits like scalability, cost-effectiveness, and accessibility from anywhere with an internet connection.

• Protocols define the rules and formats used for data transmission, ensuring that different devices or systems can understand and interact with each other.

• accuracy,
• completeness,
• consistency,
• and validity

of an organization's data. By following the process, organizations not only ensure the integrity of the data but guarantee they have accurate and correct data in their database.

The importance of data integrity increases as data volumes continue to increase exponentially. Major organizations are becoming more reliant on data integration and the ability to interpret information to predict consumer behaviour, assess market activity, and mitigate potential data security risks. This is crucial to data mining, so data scientists can use the right information.

• Every file has a unique name called filename.
• Almost all information stored in a computer must be in a file.
• Many different types of files store different types of information, eg. Program files store programs, text files store text, etc.

• Although it is primarily used for Internet-based applications, Java is a simple, efficient, general purpose language.
• Java was originally designed for embedded network applications running on multiple platforms.
• It is a portable, object-oriented, interpreted language.

The JavaScript programming language came into existence in 1995.

• It was created by Brendan Eich at Netscape Communications Corporation.
• Initially named "Mocha," it was later renamed "LiveScript" and finally "JavaScript" before its official release in December 1995 as part of Netscape Navigator 2.0.

• This technique improves efficiency and reduces channel bandwidth usage by combining the acknowledgement with the outgoing data, rather than sending it as a separate packet.

"It is unable to permit legitimate communication to pass." 

• Firewalls are designed to control network traffic, not completely block it.
•  They allow legitimate communication to pass through while blocking unauthorized or potentially harmful traffic based on predefined security rules.

• Firewalls can he implemented with hardware or software or  combination of both.
• It is often used for unauthorized Internet to prevent users from using personal networks connected to the Internet, mainly intranets.
