Answer:
Resource Ownership and Scheduling execution
Explanation:
In process characteristic the characteristic is
- Resource ownership
- Scheduling / Execution
In Resource ownership, the OS performs a protection function where unwanted interference in processes are with resources
In scheduling execution, the process has execution state and scheduled. They can be separated by resource ownership.
The dispatching of the process is the lightweight process, and it is multi-threading. The ability of the operating system supports the single concurrent process.
The process is a unit in the resource protection and protected the CPU and other processes. It contains the multiple thread execution
Each thread contains the running, ready state and saved the thread context and access the memory. Some necessary activities of the various threads are the same address space and the resources.
Generally I'd recommend not buying one online, tends to be cheaper from a shop - and better used, although their are some risks with 2nd hand devices, I think the big price cut it worth it.
If you did want to buy online, maybe Amazon or Ebay?
Answer:
Mac Address
Explanation:
The MAC address or Media Access Control is a unique identifier that each manufacturer assigns to their devices that can connect to the network. They consist of 48 bits in hexadecimal form, grouped into 12 pairs of characters and each character is formed by four binary numbers, generally separated by a colon. MAC addresses are used in the data link layer of the OSI model, specifically in the lower Medium Access Control layer. An example of a MAC address could be:
10: 68: c5: 5e: 27: 3f.
Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
<em>public void myClass(){...}</em>
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
Answer:
C. The source code has to be translated into object code.
