Answer:</h2>
<u> Port </u> a number used within a computer to identify a specific process.
<u> IP Address </u> a numerical reference to a particular device in a network.
<u> Server </u> a computer that handles requests and returns data to other computers in a network.
<h2>
Explanation:</h2>
A port number is a number used to uniquely identify a particular process, application or program on a computer. From the networking parlance, it is a logical address that uniquely identifies a process, protocol or application communicating with other process, protocol or application over a network. For example;
i. a file transfer protocol (FTP) could use a port number of 20 or 21.
ii. a simple mail transfer protocol (SMTP) could use a port number of 25
Internet Protocol (IP) address is a numerical reference or label assigned to a particular device in a network which helps to uniquely identify the device on the network. IP addresses (version 4) are expressed as a group of four numbers separated by a dot. For example, an IP address may look like this: <em>192.168.0.90</em>
A server is a computer that receives requests from other computers, processes these requests and returns some data to the other computers in a network. In reality, these servers and the computers they serve can actually be some applications or programs. Servers provide resources, data, services or programs to other computers over a network.

When looking at wireless channels, there are a couple of variables to keep in mind:
The number of other networks using what channels
The strength of the other networks on other channels
So generally speaking, channels 1, 6, and 11 are used by default. The reason for this is because there isn't any adjacent channel interference when you have all of your networks spread out in that manner. If for example, a network was using channel 3, that network would interfere with the signals one channel 1 and 6, and the bandwidth of those channels would have to be shared amongst all of those networks. This isn't optimal. Ideally you should look for a channel with less hosts who have weak signals. I know that in my area, channel 11 is the best channel to be on, because the hosts using that channel have weak signal strengths, which results in a lesser chance of those signals interfering with mine.
Answer:
One global Variable
Explanation:
when creating an animated scene also known as animation. you simply pick up a story from any subject and set that story in motion using graphic commands. animated scenes are created as time varying contents, which for every new scene there has to be a new temporary image drawn at equal time intervals.
To achieve this animation step of drawing new images at equal time interval you should introduce an endless loop also known as animation loop and one of such endless loop is a global variable. because a global variable is easily accessible throughout the program.
Answer:
(ii) int[] alpha = new int[25];
Explanation:
In JAVA in order to create an array;
int name[];
name = new int[size];
can be written like above, however, to make it shorter can be written like below;
int[] name = new int[size];
<em>Well, name is the array name you assign, int is the type of an array as integer and size you assign for an array, in that sense </em><em>(ii)</em><em> is the correct answer</em>
(ii) int[] alpha = new int[25];
alpha is the name of an array
int is the type of array as an integer
25 is the size of an array
