Answer:
How to Set Up a Home Network- Beginners Guide
Today almost every home and small office has a local network, and an Internet connection.
The home network or small area network enables multiple devices e.g. PCs,tablets etc to connect to each other, and also to connect to the internet.
In this tutorial you will learn how you to build and setup a home or small area network and connect it to the Internet.
Explanation:
Choosing a Wired or Wireless Network
Do You Build a wired or Wireless Network? which is best?
Early (pre 2008) home networks were predominately wired networks.
Wired networks use Ethernet over UTP cable and tend to be faster than wireless networks, which is an important consideration if you are a gamer. The simple wired home network diagram below shows a minimum setup with a switch and broadband router.

Wired Network Advantages
Fast typically 100 Mbps to 10 Gbps
Secure and reliable.
Wired Network Dis-Advantages
Doesn’t work with devices that don’t have an Ethernet port e.g. tablets and smart phones.
Not so easy and fast to setup as it requires running cables. However Homeplug or powerline adapters can be used instead.
Not so easy for visitors and mobile devices (laptops) to connect to.
Main Uses
It Is best used for network backbone i.e. connecting between router,network switches and wireless access points on different levels (floors).
discuss the communicatin process giving detailed explanation on each process
Communications is fundamental to the existence and survival of humans as well as to an organization. It is a process of creating and sharing ideas, information, views, facts, feelings, etc. among the people to reach a common understanding. Communication is the key to the Directing function of management.
A manager may be highly qualified and skilled but if he does not possess good communication skills, all his ability becomes irrelevant. A manager must communicate his directions effectively to the subordinates to get the work done from them properly.
Communications ProcessCommunications is a continuous process which mainly involves three elements viz. sender, message, and receiver. The elements involved in the communication process are explained below in detail:
1. Sender
The sender or the communicator generates the message and conveys it to the receiver. He is the source and the one who starts the communication
2. Message
It is the idea, information, view, fact, feeling, etc. that is generated by the sender and is then intended to be communicated further.
Browse more Topics under Directing
Introduction, Meaning, Importance & Principles of DirectingElements of DirectionIncentivesLeadership3. Encoding
The message generated by the sender is encoded symbolically such as in the form of words, pictures, gestures, etc. before it is being conveyed.
4. Media
It is the manner in which the encoded message is transmitted. The message may be transmitted orally or in writing. The medium of communication includes telephone, internet, post, fax, e-mail, etc. The choice of medium is decided by the sender.
5. Decoding
It is the process of converting the symbols encoded by the sender. After decoding the message is received by the receiver.
6. Receiver
He is the person who is last in the chain and for whom the message was sent by the sender. Once the receiver receives the message and understands it in proper perspective and acts according to the message, only then the purpose of communication is successful.
7. Feedback
Once the receiver confirms to the sender that he has received the message and understood it, the process of communication is complete.
8. Noise
It refers to any obstruction that is caused by the sender, message or receiver during the process of communication. For example, bad telephone connection, faulty encoding, faulty decoding, inattentive receiver, poor understanding of message due to prejudice or inappropriate gestures, etc.

Create a procedure named STATUS_SHIP_SP that allows an employee in the Brewbeans' Shipping Department to update an order status to add shipping information. The BB_BASKETSTATUS table lists events for each order so that a shopper can see the status, date, and comments as each stage of the order process is finished. The IDSTAGE column of the BB_BASKETSTATUS table identifies each stage; the value 3 in this column indicates that an order has been shipped. The procedure should allow adding a row with an IDSTAGE of 3, date shipped, tracking number and shipper. The BB_STATUS_SEQ sequence is used to provide a value for the primary key column. Test the procedure with the following information: o Basket # = 3 o Date shipped = 20-FEB-12 o Shipper = UPS o Tracking # = ZW2384YXK4957
Answer:
c
Explanation:
A procedure named STATUS_SHIP_SP that allows an employee in the Brewbeans' Shipping Department to update an order status to add shipping information is in the explanation part below.
A representative from Brewbeans' shipping division can change an order's status and add shipment details by using the PL/SQL method STATUS_SHIP_SP, as shown in the following example:
CREATE OR REPLACE PROCEDURE STATUS_SHIP_SP (
p_basket_number IN NUMBER,
p_date_shipped IN DATE,
p_shipper IN VARCHAR2,
p_tracking_number IN VARCHAR2
)
IS
v_status_id NUMBER;
BEGIN
-- Get the next value from the BB_STATUS_SEQ sequence
SELECT BB_STATUS_SEQ.NEXTVAL INTO v_status_id FROM DUAL;
-- Insert a new row into the BB_BASKETSTATUS table
INSERT INTO BB_BASKETSTATUS (STATUSID, BASKETNO, IDSTAGE, STATUSDATE, COMMENTS)
VALUES (v_status_id, p_basket_number, 3, p_date_shipped, 'Shipped: ' || p_shipper || ', Tracking Number: ' || p_tracking_number);
-- Commit the transaction
COMMIT;
-- Display a success message
DBMS_OUTPUT.PUT_LINE('Order status updated. Shipment information added.');
EXCEPTION
WHEN OTHERS THEN
-- Display an error message
DBMS_OUTPUT.PUT_LINE('Error: Unable to update order status.');
-- Rollback the transaction
ROLLBACK;
END;
/
Thus, by doing this, the procedure will be called with the specified parameters, and if successful, a new entry with the proper shipping information for basket number 3 will be added to the BB_BASKETSTATUS database.

Explanation:
In order to send and receive packets in the Internet, hosts require an IP address. What are the 2 ways a host can obtain an IP address
Answer:
Explanation:
An IP address is a 32-bit number. It uniquely identifies a host (computer or other device, such as a printer or router) on a TCP/IP network.
IP addresses are normally expressed in dotted-decimal format, with four numbers separated by periods, such as 192.168.123.132. To understand how subnet masks are used to distinguish between hosts, networks, and subnetworks, examine an IP address in binary notation.
For example, the dotted-decimal IP address 192.168.123.132 is (in binary notation) the 32-bit number 110000000101000111101110000100. This number may be hard to make sense of, so divide it into four parts of eight binary digits.
These 8-bit sections are known as octets. The example IP address, then, becomes 11000000.10101000.01111011.10000100. This number only makes a little more sense, so for most uses, convert the binary address into dotted-decimal format (192.168.123.132). The decimal numbers separated by periods are the octets converted from binary to decimal notation.
For a TCP/IP wide area network (WAN) to work efficiently as a collection of networks, the routers that pass packets of data between networks don't know the exact location of a host for which a packet of information is destined. Routers only know what network the host is a member of and use information stored in their route table to determine how to get the packet to the destination host's network. After the packet is delivered to the destination's network, the packet is delivered to the appropriate host.
For this process to work, an IP address has two parts. The first part of an IP address is used as a network address, the last part as a host address. If you take the example 192.168.123.132 and divide it into these two parts, you get 192.168.123. Network .132 Host or 192.168.123.0 - network address. 0.0.0.132 - host address.
The second item, which is required for TCP/IP to work, is the subnet mask. The subnet mask is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network.
In TCP/IP, the parts of the IP address that are used as the network and host addresses aren't fixed. Unless you have more information, the network and host addresses above can't be determined. This information is supplied in another 32-bit number called a subnet mask. The subnet mask is 255.255.255.0 in this example. It isn't obvious what this number means unless you know 255 in binary notation equals 11111111. So, the subnet mask is 11111111.11111111.11111111.00000000.
Lining up the IP address and the subnet mask together, the network, and host portions of the address can be separated:
11000000.10101000.01111011.10000100 - IP address (192.168.123.132)
11111111.11111111.11111111.00000000 - Subnet mask (255.255.255.0)
The first 24 bits (the number of ones in the subnet mask) are identified as the network address. The last 8 bits (the number of remaining zeros in the subnet mask) are identified as the host address. It gives you the following addresses:
11000000.10101000.01111011.00000000 - Network address (192.168.123.0)
00000000.00000000.00000000.10000100 - Host address (000.000.000.132)
So now you know, for this example using a 255.255.255.0 subnet mask, that the network ID is 192.168.123.0, and the host address is 0.0.0.132. When a packet arrives on the 192.168.123.0 subnet (from the local subnet or a remote network), and it has a destination address of 192.168.123.132, your computer will receive it from the network and process it.
Almost all decimal subnet masks convert to binary numbers that are all ones on the left and all zeros on the right. Some other common subnet masks are:
Decimal Binary 255.255.255.192 1111111.11111111.1111111.11000000 255.255.255.224 1111111.11111111.1111111.11100000
Internet RFC 1878 (available from InterNIC-Public Information Regarding Internet Domain Name Registration Services) describes the valid subnets and subnet masks that can be used on TCP/IP networks.

A. RAM is not volatile, which means that it is more reliable than a hard disk. A hard disk is volatile, which means that it is vulnerable to electronic interference.
B. RAM is volatile, which means that it does not retain information in memory after powering down. A hard is not volatile, which means that it retains information in memory after powering down.
C. RAM is not volatile, which means that it retains information in memory after powering down. A hard disk is also not volatile, which means that it retains information in memory after powering down.
D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.
Answer:
D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.
Explanation:
Most RAM (random access memory) used for primary storage in personal computers is volatile memory. Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost. Non-volatile memory has a continuous source of power and does not need to have its memory content periodically refreshed.
Answer:
Explanation:
RAM can be accessed faster than hard drive. – Any changes made to the file will be present in RAM while once the changes are saved it is copied to the hard drive permanently. – RAM needs power to store data, hard drives do not.

Write a function remove_duplicates that removes duplicates from an array. For example, if remove_duplicates is called with an array containing 1, 4, 9, 16, 9, 7, 4, 9, 11 … then the array is changed to 1, 16, 7, 4, 9. 11. Your function should have a reference parameter for the array size that is updated when removing the duplicates
The function is an illustration of loops
Loops are used to perform repetitive operations
The function in Java where comments are used to explain each line is as follows:
//This defines the remove_duplicates function
public static int remove_duplicates(int arr[], int n){
//If the length of the array is 0 or 1, then return the original array
if (n == 0 || n == 1) {
return n;
}
//This creates a new array
int[] newArr = new int[n];
//This initializes the index of the array to 0
int ind = 0;
//This iterates through the original array
for (int i = 0; i < n - 1; i++) {
//The following loop populates the new array with the unique elements of the original array
if (arr[i] != arr[i + 1]) {
newArr[ind++] = arr[i];
}
}
newArr[ind++] = arr[n - 1];
// The following loop changes the original array
for (int i = 0; i < ind; i++) {
arr[i] = newArr[i];
}
return ind;

Write a method checkCharacter() which has 2 parameters: A String, and a specified index (an int). Method checkCharacter() checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.
Ex: The method calls below with the given arguments will return the following Strings:
checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"
checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"
checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"
checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"
Your program must define the method:

int inputColon; // Used to read time format
String userInput; // User specified time
double tollAmount;
}
public static void main(String[] args) {
TollCalculation tollObj = new TollCalculation();
// Test the three samples from the specification.
System.out.println(tollObj.calcToll(7, true, false));
System.out.println(tollObj.calcToll(1, false, false));
System.out.println(tollObj.calcToll(3, true, true));
}
}
This is the requested code in java.
public class CharTest {
public static String checkCharacter(String text, int index) {
if (0 <= index && index <= text.length()) {
char ch = text.charAt(index);
if (Character.isLetter(ch)) {
return ch + " is a letter";
} else if (Character.isDigit(ch)) {
return ch + " is a digit";
} else if (Character.isWhitespace(ch)) {
return ch + " is a whitespace character";
} else {
return ch + " is an unknown type of character";
}
} else {
return "index " + index.toString() + " is out of range";
} // end if
} // end function checkChar()
public static void main(String[] args) {
// Test the three samples from the specification.
System.out.println(checkCharacter("happy birthday", 2));
System.out.println(checkCharacter("happy birthday", 5));
System.out.println(checkCharacter("happy birthday 2 you", 15));
} // end function main()
} // end class CharTest
The function checkcharacter(text, index) returns a string value describing the kind of character found at the position in text specified by index; whether it was a letter, digit, whitespace, or an unknown kind of character.
How it does that is to make use of respective functions defined within the Character class in java. That is
isLetter(char) returns a bool specifying if the char parameter is a letter.isDigit(char) returns a bool specifying if the char parameter is a digit.isWhitespace(char) returns a bool specifying if the char parameter is a whitespace character.It calls these functions in an if statement. These else part of the if statement is then executed if the character is neither a letter, digit, or whitespace.
Finally, the function main() calls checkCharacter() three times to test the function and return the results to the console.
