What term refers to components of Windows that allow external applications to access information such as file systems, threads, and registry?

• A. APIs
• B. DriverView
• C. DNSQuerySniffer
• D. NetFlow Traffic Analyzer

Answer: (A)

APIs, or Application Programming Interfaces, are the interfaces Windows provides for external applications to interact with the operating system. Through these interfaces, programs can perform tasks like accessing the file system (open, read, write files), managing threads, and reading or writing registry settings. The Windows API defines the functions, structures, and rules that govern these interactions, giving software a stable, documented way to request OS services while the operating system enforces security and stability. The other options aren’t about how software talks to the OS: DriverView is a tool for viewing installed drivers, while DNSQuerySniffer and NetFlow Traffic Analyzer are network analysis tools. They don’t describe the mechanism by which external applications access OS resources.
