How many fixtures can be on a 3 inch drain?

3 20 48

Can pipes be used over network?





Named pipes can be used to provide communication between processes on the same computer or between processes on different computers across a network. If the server service is running, all named pipes are accessible remotely.

Can a shower and toilet share the same drain?

The general answer is that the showers and toilets can use the same drain, but they should not be sharing the same waste trap arm. There are other factors to consider as well, such as whether your drains lead to the main sewer line, or if there are septic tanks that are used in your city or town.

Can a shower and toilet share a vent?

Wet vents are typically used when plumbing a bathroom group. So yes the shower can also be vented by the wet vent along with the toilet. There is one major stipulation when wet venting multiple fixtures when a toilet is one of them: the toilet must be the last fixture connected to the wet vent.

Are named pipes faster than sockets?

Named pipes are only 16% better than TCP sockets.

What is a named pipe connection?





Named pipes provide interprocess communication between a pipe server and one or more pipe clients. They offer more functionality than anonymous pipes, which provide interprocess communication on a local computer.

Are named pipes bidirectional?

Named pipes are strictly unidirectional, even on systems where anonymous pipes are bidirectional (full-duplex).

How many plumbing vents can be tied together?

You can usually tie up to eight fixtures to a single stack, but local codes differ, so it’s a good idea to check.

How many fixtures can share a vent?

A horizontal wet vent could have as few as two fixtures or as many as ten fixtures but not more than two fixtures of any type can be connected to the system. Each wet vented fixture drain shall connect independently to the horizontal wet vent.

How many plumbing vents should a house have?



At least one main vent stack is required for every building that has plumbing when connecting separately to the sewer for the building or its septic tank. The stack has to run the most direct route through open air or be ventilated to extend to open air.

Are sockets FIFO?

For named pipes (FIFO), two processes shares one file – one process writes to the FIFO, and the other reads from it. For a socket, the processes got one “file” (“Everything is a file”) each, and a connection is established between them – which of course really happens through network ports.

What is IPC and TCP?

TCP Application Protocol is an IPC (Inter-process Communication) created to provide common remote interface for between applications.

Is IPC fast?



This method is pretty fast and works on Windows 8 Developer Preview, too (see my benchmark). Any kind of data can be transported this way, by serializing it on the sender, and deserializing it on the receiver side. It’s also simple to implement sender and receiver message queues, to make the communication asynchronous.

Which IPC mechanism is best?

The IPC shared semaphore facility provides process synchronization. Shared memory is the fastest form of interprocess communication. The main advantage of shared memory is that the copying of message data is eliminated. The usual mechanism for synchronizing shared memory access is semaphores.

Where is IPC used?

Typically, applications can use IPC, categorized as clients and servers, where the client requests data and the server responds to client requests. Many applications are both clients and servers, as commonly seen in distributed computing.

What is IPC$ in Windows?

The IPC$ share is created by the Windows Server service. This special share exists to allow for subsequent named pipe connections to the server. The server’s named pipes are created by built-in operating system components and by any applications or services that are installed on the system.

What is null share?



A ‘null session share’ is a share which is accessible without login data, with ‘null credentials’. They are useful to give Windows services access to a share because Windows services are running in the ‘Local System’ account and can access this type of share only.

What is IPC connection?

Interprocess Communication (IPC) is a mechanism for establishing a connection between processes, running on two computers or on a single multitasking computer, to allow data to flow between those processes.
