MDI, refers to Multiple Document Interface; which means that you can have one main window programming application; which can also be used as a container for opening/and, closing other related sub-windows.
SDI, refers to Single Document Interface; which means that the entire program is written to work/operate inside of only one single window, alone.
SDI is a Single Document Interface. As opposed to MDI which is a Multiple Document Interface. the difference is solely in the number of documents that can be opened at one time in each instance of the application. With SDI only one document can be open whereas with MDI many documents can be open.
SDI is a single document interface while MDI is a multiple document interface. With SDI applications, only one document can be open in each instance of the application. With MDI, several documents can be opened within the same instance of the application. Your web browser is an example of an MDI application where web pages can be opened in new tabs within the same instance of the browser, or opened in a new window entirely (a new instance). Web pages can also be freely dragged/dropped between instances. Windows notepad is an example of an SDI application. The application can only open one document at a time. If you open another document, the current document will be closed. To work on two or more documents simultaneously, you must load separate instances of Notepad for each document. A document can also have several views associated with it but this has nothing to do with MDI. As an example, consider an HTML web page designer which shows two views of the same document: one containing the HTML code itself and another containing the page view where you can drag and drop individual elements. Changing one automatically changes the other because they are simply different views of the same document.
The obvious answer is that it allows you to view more than one document or type of document at the same time using the same instance of the application. With SDI (single document interface), each document is loaded in a completely separate instance of the application. There are merits to both approaches, but in more recent times applications are more a hybrid of MDI and SDI, allowing individual documents to be completely detached from the MDI main frame. With multi-monitor desktops this becomes extremely useful as the application window no longer needs to be full-screen in order to get the best view of the documents.

MDI is Multiple Document Interface. It is not strictly a VB issue. An MDI application, such as Word, creates an MDI document view for each file that is open. You can have one or many open at the same time. You can also have different views of the same document, if desired. You can switch between them, tile them, cascade them, or move them around. If they are not maximized, you can see more than one at a time. Its the same kind of interface as in the host operating system, except that it is application instance specific. Most MDI interfaces limit the child view to be within the parent window's frame, but non-limited applications are possible with current versions of the API. In any case, support for MDI comes from the application, which must provide message handlers for each user interface event. Some modern IDE's, such as VS2008, provide "automatic" support for MDI, but it is helpful to understand the underlying API.

Multiple document interfaces (MDI) are used in applications where opening two or more files within the same process is desirable. With a single document interface (SDI), if the user wishes to open two or more files, separate instances of the process must be loaded.
MDI is an abbreviation which stands for Metered Dose Inhaler. MDI adjustment therefore refers to the alterations that are made to make it suitable.

In digital video broadcast (DVB), SDI is Serial Digital Interface an uncompressed form of A/V signal and ASI is Asynchronous Serial Interface an compressed form of A/V signal. The SDI signal hold the pids(audio, video, subtitle ...) of one channel, ASI can hold pids from multiple channels and in some cases (satelite uplink) some pids who describe the transponder(NIT, TID...)
