In object-oriented programming, the behavior of an object is defined by its methods. So the correct answer is C.

Object-oriented programming is a type of programming paradigm that is based on the concept of "objects." It is a programming paradigm that focuses on the creation of software programs through the use of objects, which are data structures that contain attributes and methods. These methods define the behavior of an object in object-oriented programming.

The programming language is defined by its classes, objects, and methods. Classes are the blueprints for objects that define their structure, properties, and behavior. An object is an instance of a class, with its own unique values for each property. Finally, methods define the behavior of an object by allowing it to perform actions or manipulate data. So, methods are responsible for defining the behavior of an object in object-oriented programming.Thus the correct answer is option-c.

When running several applications on a Windows server computer that read and write database files stored on the D: volume of an internal disk, a likely reason for poor performance is disk I/O contention.

When two or more threads contend for the same resource or I/O requests, I/O contention happens. With increased concurrency in multi-core systems, I/O performance can become a bottleneck for database performance.

A likely reason for poor performance when running applications on a Windows server computer that reads and writes database files stored on the D: volume of an internal disk is that it could be experiencing disk I/O contention. When the input/output operations of various processes interfere with each other, it leads to disk I/O contention, which results in decreased disk performance.

Disk I/O contention may be reduced by balancing I/O across a range of storage hardware. This involves storing heavily accessed objects on high-performance storage hardware and less frequently accessed objects on less expensive storage hardware, among other strategies to improve performance.

A log file is a simple text file that contains an account of significant events that occurred when a software program is running. Logs are used to help developers identify, diagnose, and troubleshoot problems. Because logs are not deleted automatically, they can become large over time, and maintenance may be required to avoid data corruption or to improve system performance. Error messages and stack traces are two other ways to diagnose software issues.

An error message is a statement that informs the user or system administrator that a computer problem has arisen, which must be rectified.
