A blocking system call is used in computer programming to pause the execution of a program until a certain condition is met. This allows the program to wait for input or output operations to complete before continuing. The purpose of a blocking system call is to synchronize the flow of a program and ensure that tasks are completed in the correct order.

What is layered architecture of computer network?
1.The process of establishing a link between two devices to communicate and share information is complex. 2. The communication functions are grouped into manageable sets called as layer. 3. The design process of layer architecture is very simple as the function of each layer and their interaction are well defined. 4. It provides flexibility to modify network services. 5. Addition of new services and management of network architecture is easy. 6. Due to segmentation it is easy to solve complex problems.
How connectionless communication between a client and a server proceeds when using sockets?
Both the client and the server create a socket, but only the server binds the socket to a local endpoint. The server can then subsequently do a blocking readcall in which it waits for incoming data from any client. Likewise, after creating the socket, the client simply does a blocking call to write data to the server. There is no need to close a connection.
Are people the most important element in a computer system?
Yes. Computers are tools and tools require operators to fulfil their functionality. Without users, programmers and maintenance engineers, computers would be useless, inanimate objects with no purpose whatsoever. Although much of what a computer does can be automated, computers are not self-aware and cannot think for themselves, therefore some measure of user-interaction is required, no matter how occasionally. The term "peopleware" was coined for this purpose, because computers require hardware, software and peopleware in order to be functional.

It should only be used by device handling code that knows exactly what the effect will be.
