<u>Implication of technological literacy to a teacher training today
:</u>
- First of training has to be under technology literacy before training starts. Trainer also should have enough knowledge on technology literacy.
- Trainer can take printed materials to share the document on the topic which to be covered and circulated to trainers
- Since it given as general topic, training teacher has to cover the following topic, general on computer and purpose of computer today's life, life cycle of computer grown from old PC to laptop and tablet.
- Next topic such be covered operating system and explain about the operating system and different technology is used.
- Revolution on technology should be also covered and explained in details.
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.
There are three types of traffic in an IP network:
1. Unicast - one-to-one traffic (traffic from one sender to one receiver)
2. Multicast - one to many traffic (one sender and more receivers)
3.Broadcast - every device in the network will receive the packet
So, the broadcast traffic <span>always goes to all devices in a subnet. </span>
Answer:
Explanation:
1. The answer is No, interface cannot have constructors. ... In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).
2.A final class is considered complete and can not be subclassed (It's methods can not be overridden ). In case of abstract class, we have to proved implementation to abstract methods in subclasses. A final class can not have abstract methods and an abstract class can not be declared final.
3.private constructors are acceptable, however the class should be marked final instead, as doing so means the class is to be extended.
4.Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated(i.e an object cannot be created) but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.
