Parallel processing involves taking a large task, dividing it into several smaller tasks, and then working on each of those smaller tasks simultaneously. This is parallel processing at work. Instead of checking out one customer at a time, your grocer can now handle several at a time.

There are multiple types of parallel processing, two of the most commonly used types include SIMD and MIMD. SIMD, or single instruction multiple data, is a form of parallel processing in which a computer will have two or more processors follow the same instruction set while each processor handles different data.

• Pipelining: reduce the effective critical path by introducing pipelining latches. along the critical data path. • Parallel Processing: increases the sampling rate by replicating hardware so. that several inputs can be processed in parallel and several outputs can be. produced at the same time.

Fifth Generation

parallel processing: running a process on more than one processor. Multiprocessing A processing technique in which multiple processors or multiple processing cores in a single computer each work on a different job. Multiprocessing means the use of two or more Central Processing Units (CPU) at the same time.

There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism.

The main difference between parallel and distributed computing is that parallel computing allows multiple processors to execute tasks simultaneously while distributed computing divides a single task between multiple computers to achieve a common goal.

Scalability: As distributed systems do not have the problems associated with shared memory, with the increased number of processors, they are obviously regarded as more scalable than parallel systems.

Simply stated, speedup is the ratio of serial execution time to parallel execution time. For example, if the serial application executes in 6720 seconds and a corresponding parallel application runs in 126.7 seconds (using 64 threads and cores), the speedup of the parallel application is 53X (6720/126.7 = 53.038).

Process is the execution of a program that performs the actions specified in that program. It can be defined as an execution unit where a program runs. The OS helps you to create, schedule, and terminates the processes which is used by CPU. A process created by the main process is called a child process.

Advantages of Distributed System over Independent PCs

• Data Sharing: It is always possible to have people working independently on their.
• Device Sharing: Data are not the only things to be shared.
• Communication: Another reason to connect a group of isolated computers into a.

Scalability: In distributed computing systems you can add more machines as needed. Flexibility: It makes it easy to install, implement and debug new services. Fast calculation speed: A distributed computer system can have the computing power of multiple computers, making it faster than other systems.

Advantages of distributed data processing (DDP)

• Inexpensive:
• Easy to replace remote computers:
• Optimized processing:
• Easy to expand:
• Parallel processing:
• Better performance:
• Backup of data:
• Local data synchronization:

The main goal of a distributed system is to make it easy for users to access remote resources, and to share them with other users in a controlled manner. Resources can be virtually anything, tyoical examples of resources are printers, storage facilities, data, files, web pages, and networks.

An important goal of a distributed system is to make it easy for users (and applications) to access and share remote resources. For example, it is cheaper to have a single high-end reliable storage facility be shared then having to buy and maintain storage for each user separately.

1 Answer. WhatsApp or most of the other messaging apps rarely work on a peer to peer basis. If your friend had their app open or at least the app process running there might be a live connection to the server. WhatsApp will use that connection to send them your messages.
