Answer:
Command remembering issues.
Explanation:
The biggest challenge my company will face when working on Linux is remembering issues of the commands. The commands in Linux are a bit difficult to remember as they are complicated bit but practice can solve this issue. "Practice makes a man perfect" this well known saying suggests that practice can make perfect and this well known saying also works with Linux the more practice the employees do the more perfect they get.
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.
You need to provide "the following", otherwise other users cannot answer your question.
However, the Java operator for "not equal to" is "!=".
// For example.
if (1 != 2) {
System.out.println("1 doesn't equal 2");
}
The if-statement in the code above will always run, since 1 is not equal to 2.
Answer:
1. Classes and objects
2. Inheritance
3. Polymorphism
4. Data hiding/ encapsulation
5. Interfaces.
Explanation:
Classes and objects depict the major component of the OOP (object oriented programming). It explains the object like a ball in a soccer game development.
The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.
In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.
