Client server architecture

In this set up, the servers are workstations which perform computations or provide services such as print service, data storage, data computing service, etc. The servers are specialized workstations which have the hardware and software resources particular to the type of service they provide.

Examples 

1. Server providing data storage will possess database applications.

2. Print server will have applications to provide print capability.

The clients, in this set up, are workstations or other technological devices which rely on the servers and their applications to perform the computations and provide the services and needed by the client.

The client has the user interface needed to access the applications on the server. The client itself does not performs any computations while the server is responsible and equipped to perform all the application-level functions.

The clients interact with the server through the internet.

Clients can be either thin client or thick (fat) client.

The differences in them are described below. 

1. Thin client, as per the name, performs minimal processing. Thick or fat client has the computational ability necessary for the client.

2. The thin client possesses basic software and peripherals and solely relies on the sever for its functionalities. Fat client has the resources needed to do the processing.

3. The user interface provided by the thin client is simpler and not rich in multimedia. The user interface provided by the fat client is much better and advanced.

4. Thin client relies heavily on the server. Fat client has low dependency on the server.

5. In the thin client set up, servers are present in more number. In this set up, servers are present in less number.

6. Each server handles a smaller number of thin clients since all the processing is done at the server end. Each server handles more thick clients since less processing is done at the server end.

Using the C language, write a function that accepts two parameters: a string of characters and a single character. The function

Sav [38]

Answer:

#include <stdio.h>

void interchangeCase(char phrase[],char c){

for(int i=0;phrase[i]!='\0';i++){

if(phrase[i]==c){

if(phrase[i]>='A' && phrase[i]<='Z')

phrase[i]+=32;

else

phrase[i]-=32;

}

int main(){

char c1[]="Eevee";

interchangeCase(c1,'e');

printf("%s\n",c1);

char c2[]="Eevee";

interchangeCase(c2,'E');

printf("%s\n",c2);

}

Explanation:

Create a function called interchangeCase that takes the phrase and c as parameters.
Run a for loop that runs until the end of phrase and check whether the selected character is found or not using an if statement.
If the character is upper-case alphabet, change it to lower-case alphabet and otherwise do the vice versa.
Inside the main function, test the program and display the results.

What does a proxy server do? Help please!!

Svet_ta [14]

Answer:

A proxy server acts as a gateway between you and the internet. It's an intermediary server separating end users from the websites they browse. Proxy servers provide varying levels of functionality, security, and privacy depending on your use case, needs, or company policy.

Write a method called findNames that meets the following specs: It takes two arguments: a list of strings, allNames, and a strin

Anna11 [10]

Answer:

public class Solution {

public static void main(String args[]) {

String[] allNames = new String[]{"Bob Smith", "Elroy Jetson", "Christina Johnson", "Rachael Baker", "cHRis", "Chris Conly"};

String searchString = "cHRis";

findNames(allNames, searchString);

}

public static void findNames(String[] listOfName, String nameToFind){

ArrayList<String> resultName = new ArrayList<String>();

for(String name : listOfName){

if (name.toLowerCase().contains(nameToFind.toLowerCase())){

resultName.add(name);

}

for(String result : resultName){

System.out.println(result);

}

Explanation:

The class was created called Solution. The second line define the main function. Inside the main function; we initialized and assign an array called allNames to hold the list of all name. Then a String called searchString was also defined. The searchString is the string to search for in each element of allNames array. The two variables (allNames and searchString) are passed as argument to the findNames method when it is called.

The method findNames is defined and it accept two parameters, an array containing list of names and the name to search for.

Inside the findNames method, we initialized and assigned an ArrayList called resultName. The resultName variable is to hold list of element found that contain the searchString.

The first for-loop goes through the elements in the allNames array and compare it with the searchString. If any element is found containing the searchString; it is added to the resultName variable.

The second for-loop goes through the elements of the resultName array and output it. The output is empty if no element was found added to the resultName variable.

During comparison, the both string were converted to lower case before the comparison because same lowercase character does not equal same uppercase character. For instance 'A' is not same as 'a'.
