True. EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary routing protocol that uses nonperiodic, partial, and bounded updates to reduce network traffic and improve convergence time.
Routing is the process of directing data packets between different networks or subnets in order to reach their intended destination. A router is a device that is used to connect multiple networks together and direct traffic between them. Routers use routing tables, which contain information about the available paths and destinations on the network, to determine the best path for a packet to take. They may use various routing protocols, such as OSPF, BGP, or EIGRP, to exchange routing information with other routers on the network. Routing is a critical component of any network, as it ensures that data packets are delivered to their intended destinations in a timely and efficient manner.

46. T F A static member function may refer to nonstatic member variables of the same class, but only after an instance of the class has been defined.
True. A static member function can refer to nonstatic member variables of the same class, but only after an instance of the class has been defined.
A static member function is a member function of a class that is associated with the class rather than an instance of the class. This means that a static member function can be called using the class name, without the need to create an instance of the class. However, since a static member function is associated with the class and not with any particular instance of the class, it cannot access non-static member variables or functions directly. This is because non-static member variables and functions are associated with specific instances of the class. That being said, a static member function can refer to non-static member variables of the same class, but only after an instance of the class has been defined. This is because non-static member variables are associated with specific instances of the class, and an instance must exist before the static member function can refer to them.

A group of similar rows or records in a table is called a file.True False
Answer:
False.
Explanation:
A group of similar rows or records in a database is called a table. A file, on the other hand, is a collection of related data or information that is stored on a computer under a single name. Files can contain various types of data, including text, images, audio, video, and software programs.
Any items typed on the command-line, separated by space, after the name of the class are considered to be one or more arguments that are to be passed into the main method.
When running a Java program from the command-line, any additional input provided after the name of the main class is considered to be arguments to the program.
These arguments are then passed into the main method of the class as an array of strings. For example, if you have a class called "MyProgram" with a main method, and you run it with the command "java MyProgram arg1 arg2 arg3", then "arg1", "arg2", and "arg3" would be passed into the main method as an array of strings. It's important to note that these arguments are separated by spaces, and must be provided in the correct order expected by the program.
