CLR stands for Common Language Runtime, a component of .NET framework that manages execution of .NET programs.

• CLR is responsible for memory management, security, and exception handling.

• It compiles code into an intermediate language (IL) and then executes it.

• CLR allows for language interoperability, meaning that code written in different languages can be compiled to the same IL and run on the same runtime.

• Examples of languages that can run on CLR include C#, VB.NET, F#, and ma...read more

Cookies are small text files stored on a user's computer by a website to remember user preferences and login information.

• Cookies are used to track user activity on a website

• Persistent cookies remain on the user's computer until they expire or are deleted

SQL injection is a type of cyber attack where malicious SQL statements are inserted into an entry field to manipulate the database.

• SQL injection is a common attack on web applications that use SQL databases.

• Attackers can use SQL injection to bypass authentication, steal data, or modify data.

• SQL injection can be prevented by using prepared statements, input validation, and limiting database privileges.

• Example: If a login form is vulnerable to SQL injection, an attacker can ent...read more

Validations used in project

• Input validation to ensure correct data type and format

• Data validation to ensure data integrity and consistency

OSI model is a conceptual framework for understanding network communication. Satellite communication is a type of wireless communication.

• OSI model has 7 layers, each with a specific function in network communication

• Networking involves connecting devices to share resources and information

• Satellite communication uses satellites to transmit signals over long distances

• Satellite communication is used for TV broadcasting, GPS, and internet access in remote areas

Stored procedures are precompiled SQL statements that can be saved and reused in a database.

• Stored procedures can improve performance by reducing network traffic and improving security.

• They can be used to encapsulate business logic and provide a consistent interface to the database.

• Parameters can be passed to stored procedures, allowing for dynamic queries.

• Examples of stored procedures include ones that retrieve data, insert data, or update data in a database.

Views in SQL are virtual tables that are based on the result of an SQL statement.

• Views are created using the CREATE VIEW statement.

• They can be used to simplify complex queries.

• They can also be used to restrict access to sensitive data.

• Views are updated automatically when the underlying tables are updated.

• They can be used to join multiple tables into a single view.

Web services are a broader concept that includes various technologies, while WCF is a specific technology for building distributed systems.

• Web services are based on open standards like HTTP, XML, and SOAP, while WCF uses a more flexible messaging system.

• Web services can be consumed by any platform or language, while WCF is primarily used in the .NET framework.

• Web services are typically used for interoperability between different systems, while WCF is more focused on building ...read more
