Answer:
spanning-tree portfast bpduguard
Explanation:
spanning- tree protocol (STP) is a layer 2 protocol in the OSI model. It is automatically configured in a switch to prevent continual looping of BPDUs, to avoid traffic congestion. The fastport bpduguard is only applicable in non-trunking access in a switch. It is more secure to configure the fastport mode in switch port connected directly to a node, because there are still bpdus transfer in a switch to switch connection.
BPDUs Guard ensures that inferior bpdus are blocked, allowing STP to shut an access port in this regard.
Answer:
The method can be accessible from main method of any class.
Explanation:
Main method is the entry point of a program, which means when you start you program the first thing to execute is the main method.
public static void main(String[] args){
// Your code here
}
In the given display method you have int, double and char data types as a arguments. So in order to call display method you need to understand the datatype that you want to pass.
int only takes integers without decimal points.
double take numbers with decimal points.
and char only tak one character
so in order to call display method we need to pass those arguments in right order.
Below is the main method which will call the display method in a right way
public static void main(String[]args){
display(25,50000.00,'T');
}
Output
The values are 25, 50000.0, and T

Answer:
There are different kinds of operating systems: such as Windows, Linux and Mac OS
There are also different versions of these operating systems, e.g. Windows 7, 8 and 10
Operating systems can be used with different user interfaces (UI): text user interfaces (TUI) and graphical user interfaces (GUI) as examples
Graphical user interfaces have many similarities in different operating systems: such as the start menu, desktop etc.
When you can recognize the typical parts of each operating system’s user interface, you will mostly be able to use both Windows and Linux as well as e.g. Mac OS.
THE ROLE OF OPERATING SYSTEM IN THE COMPUTER
An operating system (OS) is a set of programs which ensures the interoperability of the hardware and software in your computer. The operating system enables, among other things,
the identification and activation of devices connected to the computer,
the installation and use of programs, and
the handling of files.
