how many usable host addresses are available for each subnet when 4 bits are borrowed from a class C IP address
Answer:
The answer is "14".
Explanation:
Let the IP address [tex]= 196.45.204.0[/tex]
When it borrowed 4 bits
[tex]\therefore\\\\ subnet = 28[/tex]
[tex]IP= \frac{196.45.204.0}{28}\\\\ 28 \to 11111111.11111111.11111111.11110000[/tex]
If the borrowed bits are left out then:
The Number of useable host addresses:
[tex]= {(2^4) - 2} \\\\ = 16-2\\\\ =14[/tex]
Describe the major issues surrounding the decisions to build and/or host your own e-commerce Web site or to outsource some aspects of site development. Include the advantages and disadvantages of each decision.
Answer:
Explanation:
The main issue with this is the time and cost of buildling and maintaining your server. You will need to know how to build a server to host your own e-commerce site but will also need to learn how to manipulate data. This includes being able to save and pull data from the server. Once you have this done then the rest is easy since that is the biggest disadvantage of hosting your own site. The biggest advantage is that you have full control over your data and do not have to pay monthly fees and hidden fees to any hosting site.
The major issue surrounding the decisions to build or hosting of your own e-commerce is that one will need a multiskilled staff.
It should be noted that when an individual wants to build an e-commerce site, they'll need a multiskilled staff like graphic artists, programmers, project managers, and web designers.
The person will also purchase the appropriate hardware and software. There are also several risks that come with building a site from scratch. The cost involved is also high as the requirements to build the site are complex.

Which of these method of ArrayList class is used to obtain present size of an object/
a. size()
b. length()
c. index()
d. capacity()
Answer:
The method of ArrayList class which is used to obtain the present size of an object is:
a. size()
Explanation:
In ArrayList, the size() method provides the number of objects available in the collection, array, or list. In Java programming, ArrayList forms a part of the collection framework and has a set of methods to access elements and modify them. An ArrayList does not have a fixed-size data structure, unlike an Array, but continues to expand in size.
An array similar to a phone book has 1000 names arranged as names [0], names[1]....names[999]. Nancy wants to search a name X in this array. Which of the following preconditions must she ensure to perform a binary search?
The list has a large number of names.
The name X is present in the list.
In addition to the two statements above, which of the following is correct?
a. There should be no duplicates in the list.
b. The names in the list should be alphabetical order.
c. The name X should occur near the middle of the list.
Answer:
Preconditions that she must ensure to perform a binary search are:
The list has a large number of names.
The name X is present in the list.
c. The name X should occur near the middle of the list.
Explanation:
Nancy's binary search for a name X should begin by comparing an element in the middle of the array or list with the name X (target value). If this name X's value matches the value of an element in the list, Nancy must return its position in the array. If the name X's value is less than the element's value, Nancy will continue the search in the lower half of the array. Usually, the name X should occur near the middle of the list or array.
What is the output of the following program
#include
int toronto (int x)
{
int w;
if (x == 0) w = 1; else w = toronto (x-1);
return (w);
}
int main (void)
{
int a = 2;
printf ("%d", toronto (a));
return (0); }
a. 0
b. 1
c. 2
d. -1
e. none of these
Answer:
The output is 1
Explanation:
Analysing the flow of program (We start from the main method)
The main begins here
int main (void) {
This line declares a as integer and also initializes it to 2
int a = 2;
This line passes 2 to the function names toronto and also prints the result of the function
printf ("%d", toronto (a));
return (0); }
The toronto function begins here.
Note that the function receives 2 as its argument and this is saved in variable x
int toronto (int x) {
This declares w as integer
int w;
If x is 0, w equals 1
if (x == 0) w = 1;
If otherwise
else
This reduces x by 1 and performs a recursion
w = toronto (x-1);
return (w);
}
Because of the structure of the if condition in the toronto function, the function will be repeated until x is 0.
And when x = 0; w = 1
This returns w (i.e. 1) back to the main function where 1 is printed as the output
return (w);

Describe the action of the indexOf and substring methods. Explain how these methods can be used to divide an existing string into two parts. Why is it necessary to add 1 to the position of the space when copying the remainder of the string
Answer:
The indexOf is a string method used to get the index of a character in a string. It can be used with the slice, substr, or subString methods to divide a string into two or more parts.
var words = "hello John Snow";
var A = words.slice(0, words.indexOf("John"));
var B = words.slice(words.indexOf("John") + 1, words.length());
One (1) is added to the space of avoid repeating a character in both new strings.
Explanation:
The indexOf method is a built-in method in Javascript used to get the index of a character or word in a string variable. The return integer number can be used in a method like a slice() to divide the string and them to other string variables.

What does a wireless LAN (WLAN) act as to a wired network?
a. Gateway
b. Bridge
c. Switch
d. Router
Answer:
The answer is option A "Gateway"
Explanation:
A wireless LAN (WLAN) connects at least two computers or devices using some wireless distribution technique (normally spread-spectrum or OFDM radio), and as a rule gives a connection through a gateway/modem to the more extensive Web. This gives clients the portability to move around through a local coverage and still be connected with the network.
Wireless LANs have gotten famous in the home because of simplicity of establishment, the expanding ubiquity of PC and hand-held PCs, and commonality, due the accessibility of (frequently free) wireless network on schools and in open organizations.
A WLAN, or wireless LAN, is a network that permits gadgets to connect and communicate wirelessly. Dissimilar to a traditional wired LAN, in which gadgets communicate over Ethernet links, devices on a WLAN connects by means of Wi-Fi. They can speak with different gadgets on the network a similar way they would on a wired network.
The essential contrast is the way the information is communicated. In a LAN, information is communicated over actual links or cables in a progression of Ethernet packets. In a WLAN, bundles are communicated over the air.

True or false: In relational databases, each individual space within a row or column contains exactly one value.
Answer:
True.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores. This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
A relational database can be defined as a type of database that is structured in a manner that there exists a relationship between its elements.
Hence, in relational databases, each individual space within a row or column contains exactly one value.

Adam is writing a program that: 1) has the user guess a number, and 2) tells the user how many guesses it took to get the correct answer. But when Adam tests the program, it always outputs that it took the user one guess, even when it takes many guesses. What error did Adam most likely make, and how should it be fixed? The difference between a for loop and a while loop is that a for loop is a loop that happens for a certain number of times. A while loop happens until a certain condition is met. How do you know when to use each one? Give specific examples in your answer. What are some programs that you have used that have condition-controlled loops and count-controlled loops? Why is it important that if, elif, and else statements appear in the proper order? What are some situations where you might find it useful to use the “!” symbol in a program?
Answer:
There are two ways in which programs ... count-controlled loops; condition-controlled loops ... Sometimes it is necessary for steps to iterate a specific number of times. ... A count-controlled loop is used when the number of iterations to occur is ... the variable 'count' is used to keep track of how many times the algorithm
Explanation:
Answer:
Adam most likely forgot to add a while loop to the guessing code or didn’t add it properly, meaning that instead of letting him guess multiple times it just continues the code, all he needs to do is add a while loop to fix the line of code.
