Business Intelligence (BI) systems are designed to analyze data and provide actionable information that aids in strategic decision-making. The purpose of a BI system is not merely to integrate departments or provide access to raw data, nor is it limited to using only proprietary data. Instead, BI systems enable organizations to make informed decisions based on the analysis of a wide range of data. Here's how they work:

1. Data Collection: BI systems collect data from various sources within the organization, including all departments.

2. Data Storage: The collected data is then stored in a secure and accessible manner, often in data warehouses.

3. Data Analysis: BI tools analyze this data to find patterns, trends, and insights. This analysis can include descriptive analytics to understand past performance and predictive analytics to forecast future trends.

4. Information Presentation: The insights are then presented in an understandable format, such as reports or dashboards, which decision-makers can use to guide their strategic choices.

* The system component that allows a collection of computers to communicate with each other is the network.

* Explanation:- Networks enable communication between computers, allowing data exchange, resource sharing, and collaboration.

*

Therefore, the correct answer is B. Network.

Software protection involves safeguarding software applications from unauthorized use, distribution, or reproduction. Various methods are employed to protect software, but one of the most frequently used approaches is through copyrights. Here's why:

1. Copyrights:

o Definition: Copyright protection grants exclusive rights to the creator or owner of the software. It prevents others from copying, distributing, or using the software without permission.

o How It Works:

When a software developer creates an original program, they automatically hold the copyright to it.

The copyright holder can specify licensing terms and conditions, allowing or restricting certain uses.

Users must comply with these terms to legally use the software.

o Benefits:

Legal Protection: Copyright laws provide legal recourse against infringement.

Revenue Control: Developers can license their software and generate revenue.

Innovation Encouragement: Copyright protection encourages innovation by rewarding creators.

o Reference: 12

2. Other Methods:

o GNU General Public License (GPL): GPL is an open-source license that allows users to freely use, modify, and distribute software. However, it requires derivative works to be open-source as well.

o Fair Use: Fair use is a legal doctrine that permits limited use of copyrighted material without permission for purposes such as criticism, commentary, or education.

o Trademarks: Trademarks protect brand names, logos, and symbols associated with software. While not directly related to software protection, trademarks play a role in branding and identity.

In summary, while other methods exist, copyrights remain a fundamental and frequently used approach to protect software from unauthorized use and ensure developers' rights are respected.

A proxy server serves several essential functions in network communication:

1. Security and Privacy:

o A proxy server acts as a gateway between the user's device and the internet. When a user sends a request (e.g., accessing a website), it first goes through the proxy server.

o The proxy server hides the user's IP address, making it difficult for external entities to directly trace the user's location or identity.

o By acting as an intermediary, the proxy server provides an additional layer of security, protecting the internal network from potential threats and attacks.

2. Content Filtering and Access Control:

o Organizations often use proxy servers to control internet access for their employees. The proxy can filter requests based on predefined rules.

o For example, an organization might block access to certain websites (e.g., social media, gambling sites) or restrict access during work hours.

o Content filtering helps maintain productivity and prevent unauthorized access to inappropriate or harmful content.

3. Caching and Acceleration:

o Proxy servers can cache frequently accessed web pages, images, and files. When a user requests the same content again, the proxy serves it from its cache.

o Caching reduces the load on the internet connection and speeds up access to commonly visited sites.

o It also helps save bandwidth by minimizing redundant data transfers.

4. Load Balancing:

o In large networks, multiple proxy servers can distribute incoming requests to different web servers. This load balancing ensures efficient utilization of resources.

o By evenly distributing traffic, proxy servers prevent any single server from becoming overwhelmed.

5. Anonymity and Geolocation Bypass:

o Some users use proxy servers to hide their real IP addresses. This anonymity can be useful for privacy reasons or to bypass geolocation restrictions.

o For example, a user in one country can use a proxy server located in another country to access region-restricted content.

A join in the context of a database, specifically SQL, is an operation that combines rows from two or more tables based on a related column between them. The purpose of a join is to retrieve data that exists across multiple tables which share a common field or key. The process typically involves the following steps:

1. Identify the Tables: Determine the tables that you want to join.

2. Determine the Common Column(s): Find the column(s) that the tables share, which will be used to match rows.

3. Choose the Type of Join: Decide on the type of join that suits your needs (INNER, LEFT, RIGHT, FULL).

4. Construct the Join Query: Write the SQL statement that specifies the join condition using the ON keyword.

5. Execute the Query: Run the query in the database to retrieve the combined results.

For example, if you have an Orders table and a Customers table, and both have a CustomerID column, you can join them on this column to retrieve a list of orders along with the customer information for each order.
