Regression testing is testing the entire application after changes, while retesting is testing a specific bug fix.

• Regression testing involves testing the entire application to ensure that new code changes have not affected existing functionality.

• Retesting involves testing a specific bug fix to ensure that the issue has been resolved.

• Regression testing is typically done after every code change, while retesting is done after a bug fix.

• Regression testing helps ensure that new fe...read more

I completed my software testing course at XYZ Institute.

Avoid deadlock by implementing proper resource allocation strategies and using techniques like timeouts and resource ordering.

• Implement proper resource allocation strategies to prevent multiple processes from holding resources indefinitely.

• Use timeouts to limit the amount of time a process can wait for a resource before releasing it.

• Follow a strict resource ordering protocol to ensure processes request and release resources in a consistent order.

• Avoid circular wait by ensurin...read more

The OSI (Open Systems Interconnection) model consists of 7 layers that define the functions of a network communication system.

• Physical Layer: Deals with physical connections and transmission of raw data.

• Data Link Layer: Manages data frames and error detection/correction.

• Network Layer: Handles routing and logical addressing.

• Transport Layer: Ensures end-to-end communication and data flow control.

• Session Layer: Establishes, maintains, and terminates connections.

• Presentation Laye...read more

Bugs in games refer to software defects or glitches that cause unexpected behavior or errors.

RF stands for Radio Frequency. A jammer is a device that disrupts or blocks RF signals.

• RF refers to the frequency range used in wireless communication systems.

• RF signals are used in various applications such as mobile phones, Wi-Fi, Bluetooth, and satellite communication.

• A jammer is designed to emit RF signals on the same frequency as the target device, causing interference and disruption.

• Jamming devices can be used for illegal activities like blocking cell phone signals in r...read more

A pointer in C is a variable that stores the memory address of another variable.

• Pointers are used to access and manipulate memory addresses directly.

• They are declared using the * symbol, like int *ptr;

• Pointers can be used to pass variables by reference to functions.

• Example: int *ptr; int num = 10; ptr = # *ptr = 20; // num now equals 20

Regression testing is the process of retesting modified software to ensure that the existing functionalities are not affected.

• Regression testing is performed after making changes to the software to ensure that the modifications have not introduced new bugs or issues.

• It involves re-executing previously executed test cases to verify that the existing functionalities still work as expected.

• Regression testing helps in identifying any unintended side effects of code changes and en...read more

C programming is a high-level programming language used for system programming, embedded systems, and creating software applications.

• C programming is a procedural language with a rich set of built-in functions.

• It is widely used for developing operating systems, compilers, and device drivers.

• C programs are efficient and have a close relationship with the underlying hardware.

• Example: Writing a simple 'Hello World' program in C.

No, jammer means disadvantages.

• Jammer is a device that blocks or interferes with signals, causing disruption or interference.

• It is often used to prevent communication or tracking, which can be a disadvantage in certain situations.

• For example, a jammer can be used to disrupt the signal of a GPS device, making it difficult to track a vehicle or person.

• In military operations, jammers can be used to disrupt enemy communication, but can also interfere with friendly communication.
