This is a programming paradigm that allows multiple processes or threads to execute simultaneously, improving performance and efficiency. ----- PROGRAMMING

Which of the ff are challenges that concurrent programming introduces?

• synchronization

• communication between concurrent processes

• delay

• unsynch

This means an instance of a program.

This means a lightweight process

Apart from processes, which is another basic unit of execution?

How does processes communicate?

• Thru inter-process communication mechanisms

• Thru synchronization mechanisms

How does threads communicate?

• Thru inter-process communication mechanisms

• Thru synchronization mechanisms

These might happen because of a deadlock.

• A program might crash

• A program might freeze

• A program might run smoothly

A cause of deadlock which means one or more resources are acquired in an exclusive mode.

• Mutual Exclusion

• Hold and Wait

• No Pre-emption

• Circular Wait

A cause of deadlock which means at least one resource in exclusive mode and wait for at least another resource that has been acquired by another resource in exclusive mode.

• Mutual Exclusion

• Hold and Wait

• No Pre-emption

• Circular Wait
