Explain how garbage collection deals with circular references?

Correct Answer: All the above

Explanation:

All the above listed are debugging windows in .NET

Correct Answer: Delegates

Explanation:

A delegate declares a ref type that references a named of anonymous method. Delegates are secure and type-safe.

Correct Answer: The Net runtime knows about all the references between the objects It can identify all the circular references that are reachable from the root and hence finalize them to free them all at once if and when needed

Correct Answer: Value type : Stores the data The value of value types is stored on the managed stack They are lighter objects One variable can have only one value Reference Type : Stores the reference to the data A reference type is allocated on the heap They are heavier objects Several variables can reference the same data

Correct Answer: Wi-Fi technology is a technology used for transmitting a signal using the 80211 specifications works a lot like it does with a basic Ethernet hub: They?re both two-way forms of communication, and they both use the same frequency to both transmit and receive, often referred to a half-duplex WLANs used radio frequencies (RFs) that are radiated into the air from an antenna that creates radio waves These waves can be absorbed, refracted, or reflected by walls, water, and metal surfaces, resulting in low signal strength So because of this vulnerability to surrounding environmental factors, it?s pretty apparent that wire-less will never offer us the same robustness as a wired network can, but that still doesn?t mean we?re not going to use or run the wireless or Wi-Fi

Correct Answer: A keyword that specifies that types in a particular nemespace can be referred to without requiring their full qualified type names 'using' reserved word always come with namespaces eg using systems so because of this useful classes supplied by Microsoft which are contained by system namespace are availble for user

Correct Answer: The garbage collector assumes that all objects in the managed heap are garbage It starts walking the roots and builds a graph of all objects reachable from the roots recursively It stops when it attempts to add an object to the graph that it previously added The graph contains the set of all objects that are reachable from the application's roots Any object/s that is not in the graph is not accessible by the application, and is considered garbage Collection only occurs when the heap is full In such a case, each and every garbage object calls the Finalize method and reclaims the unused memory

Correct Answer: MainMenu component is a component that allows the display of Menus at runtime on a form Process of creating Menu using MainMenu Component: a Add MainMenu component on Windows Form b Menu designer allows deciding the structure of the main menu by selecting the Type Here area and adding the Menu Items to be displayed on the menu c Add functionality to Menu Items as required

Correct Answer: It is the folder that contains web applications The folder that has been published as virtual folder by IIS can only contain web applications

Correct Answer: Net allows developers to write program logic in at least 25 languages The classes written in one language can be used by other languages in Net This service of Net is possible through CTS which ensure the rules related to data types that all language must follow It provides set of types that are used by all NET languages and ensures NET language type compatibility
