Answer:
Check the explanation
Explanation:
A) Whenever C is sending to D, what other communications are possible?
C’s packet will be seen by A, B and D, but not by E. Thus, D can send to E at the sametime..
B) Whenever B is sending to A, what other communications are likely?
Even though B’s packet will not be seen by D, other nodes, e.g., E, or C, can’t send to D since the packets from these nodes will interfere with the packets from B at A. Therefore, other communications is not likely at the same time.
C) Whenever B is sending to C, what other communications are possible?
B’s packet will be seen by E, A and C, by not by D. therefore, E can send to D at the same point.
Answer:
Runnable.
Explanation:
Java is an all round programming language which is typically object-oriented and class-based. It was designed by James Gosling, developed by Sun microsystems and released officially on the 23rd of May, 1995. Java programming language is designed to have only a few implementation dependencies as possible because it was intended to be written once, and run on any platform.
Java makes concurrency to be available to software developers through the application programming interface (API) and the language. Also, it supports multiple threads of execution, by making each thread have its respective program counter and method-call stack, which then allow concurrent executions with other threads.
The preferred means of creating multithreaded Java applications is by implementing the runnable interface. An object of a class that implements this interface represents a task to perform. The code is public void run ().
Answer:
Windows utility program.
Explanation:
The operating system is a software used to manage the activities of various parts of the computer system. It acts as a link between the hardware, application software and the user. An example of OS is the Windows OS.
It has the kernel program that directly connects the hardware to the operating system. It provides utility programs to analyse, optimise, control and maintain devices running in the system.
Window utility program is an example of utilities in OS, used to analyse, control, optimise and maintain device and software activities for good system performance.
An example of the windows utility program is the disk defragmenter used to eliminate fragments and rearrange files and unused disk space.
