Final answer:
Pair Programming is a software development technique where two programmers collaborate at one computer. It has advantages such as improved code quality and faster problem-solving, but also disadvantages like coordination challenges and potential personality conflicts.
Step-by-step explanation:
Pair Programming is a software development technique in which two programmers work together at one computer. One programmer, known as the 'driver', writes the code, while the other, known as the 'navigator', reviews and provides input. They switch roles frequently.
The advantages of Pair Programming include improved code quality, as two sets of eyes can catch more errors, faster problem-solving as issues are resolved more quickly, increased knowledge sharing and learning, and better team communication and collaboration.
However, there are also disadvantages to Pair Programming. It requires coordination and communication between the two programmers, which can be challenging. It can also be mentally exhausting, as both programmers need to focus for extended periods of time. There is also a potential for personality conflicts or differences in coding styles that can affect productivity.
