Answer:
Data type is an attribute of the data in the computer science. It basically guide the compiler and interpreter about the data utilization in the program. Data type basically define the operation, which can be done on given data.
There are different types of data types are as follow:
Integer data type: This type if data type basically represent the integer type of data value from largest to smallest order.
For example: int p = 10;
Real data type: This type of data type is used to represent the real type of number from largest to smallest range.
For example: float b = 17.6;
Answer:
1. PANs uses Star Topology.
2. LAN uses four topology (Bus, Ring, Star and Tree).
3. MAN uses Star Topology.
4. WAN uses Bus topology.
Explanation:
1. PAN is the personnel area network, in which different personnel devices of a person are connect to each other with the help of the central computer with the help of Bluetooth, WiFi or some other medium. The central computer will work like a hub and all the devices are directly connected to the central PC. It is same as the ring topology where all the devices are connected to the central PC. So we can say that, PANs use star topology.
2. LAN is the local area network that has been established with in the premises of the organization. In this type of network, four typologies involve to complete the network connection. First is star topology, that is used to connect all the devices with the switches. Then Bus topology is used to connect all the switches with the single main cable. Ring topology is involved to connect all the switches with each other. Tree topology is used to connect different block if the organization in the form of branch to connect the central router or switch.
3. MAN is the Metropolitan Area Network which is comprise of different LANs. All the LANs are connected to the Router in the form of Star topology.
4. WAN is the wide area network. In WAN different MANs are connected to the network through single cable. This type of network uses Bus topology.

Answer:
Following are the Statement in the Java Language .
Scanner out = new Scanner( System.in); // creating the object
datum = out.nextInt(); // Read the integer value bu using the instance of scanner class
Explanation:
In the Java Programming Language The scanner class is used for taking the user input from the standard input The definition of scanner class is java.util package means that if you taking the input by using scanner class firstly importing the predefined package i.e Java.util.
The description of the above code is given below
- Scanner out = new Scanner( System.in);: This statement created the instance "out" of the scanner class which is used for taking the input.
- datum = out.nextInt(); : This statement taking the integer input and store them into the datnum variable.
