Q22. What is named piped protocols in WCF?

Answer:

A named pipe is a named, one-way or duplex pipe for communication between the pipe server and one or more pipe clients. All instances of a named pipe share the same pipe name, but each instance has its own buffers and handles, and provides a separate conduit for client/server communication. The use of instances enables multiple pipe clients to use the same named pipe simultaneously.

Q23. When to use margin and when to use padding?

Answer:

Use padding when:

• You don’t want your content to touch the edges of the container. Example: you have a bunch of <p> elements inside a div and you don’t want the text inside <p> elements to touch the div’s border:
• You want to increase the size of the element. Example: if you want to increase the size of a button:

Use margin when:

• You want to have some space around an element, or you don’t want the element to touch other elements around it:
• You want to center an element. If you give “margin: auto” to an element with fixed width, it will center that element horizontally (and vertically too if using flexbox
