Answer: Jill will have to b) merge the top three cells so that her first heading can span the width of the entire table.
Explanation: If Jill merges the top two cells, one of the cells will still remain and therefore she will not be able to span the width of the entire table. She cannot merge the top ten cells because the problem states the has 3 columns. The 10 rows occupy the entire table and are not located at the top of the table. Jill could widen the first cell, however, it will limit her table to one large column and 10 rows. The problem states that only the first heading or row should be occupying the entire width, therefore b) merges the top three cells is the correct answer.
To make her first heading span the width of the entire table which has three columns, Jill should merge the top three cells. The correct option is b. merges the top three cells.
In Microsoft Word, when creating a table, if you want to make a single cell span across multiple columns, you use the merge cells feature. Since Jill's table has three columns, merging the top three cells will create one header cell that extends over the entire width of the table, allowing for a cohesive and clear heading. This is especially useful for providing a unified title or a single descriptive heading at the top of the columns. It's important to ensure that table header cell labels are concise and clear, with captions or descriptions that clearly articulate the table's purpose and organization. In this case, Jill's merged cell can serve as a label to help interpret the cells below in her order form table, making it both functional and visually appealing.
A sequential file stored on a(n) ____________ can be updated in place.
(Points : 2) direct access storage device
paper tape
punch card file
line printer
Answer: Direct access storage device
Explanation:
The sequential file is the simple method for organization of different types of files. The files and records are basically stored in the direct access storage device in the sequentially manner so that we can directly access the particular file according to the requirement.
The direct access storage device basically allow the any file and elements to access directly from the given storage device and address. It is less time consuming method so that it increase the overall efficiency of the system.
On the other hand, all the other options are not associated for storing the sequential file. Therefore, Direct access storage device is the correct option.
The default behavior for Connector/Python is to use __________ results.
a
buffered
b
unbuffered
c
uninitialized
d
list-based
Answer: (C) Uninitialized
Explanation:
The default behavior is basically used as the uninitialized result for the connector and python. As a matter of course, MySQL Connector/Python doesn't cradle or pre-fetch results. This implies after a question is executed, your program is in charge of bringing the information.
This stays away from unnecessary memory use when inquiries return huge outcome sets. On the off chance that you realize that the outcome set is little enough to deal with at the same time, you can get the outcomes promptly by setting supported as "TRUE".
Explain what occurs when you synchronize computer and mobile devices.

September 2019 has 30 days.
Explanation:
In this program we have take two user input one for the month and other for the year Also take two variables which are used for storing the month name and no of days in a month. with the help of switch we match the cases and store the month value .After that set the date to calender with help of calendar.set(nYear, nMonth, date) method and To get the number of days from a month we use calendar.getActualMaximum(Calendar.DAY_OF_MONTH); method and finally print year and days.
In a typical configuration the total RAM capacity is less than total ROM capacity.
True
False
False
Explanation:The difference between RAM and RAM is as follows
(1) RAM (random access memory) is meant for temporary storage whereas ROM (read-only memory) is meant for permanent storage.
(2) RAM chip is volatile, means once the power is turned off, it loses the previously holding information, where as ROM is non-volatile it doesn't losses any information even though power is turned off.
(3) RAM chip is used in the normal operations of the computer, whereas the ROM chip is used mainly for the startup process of computer.
(4) Generally, A RAM can store several gigabytes (GB) of data that is up to 16 GB whereas a ROM chip can typically store that much data. It only stores several megabytes (MB) of data that is up to 4 MB.
hence, the given statement about RAM is false.
What does it mean to 'instantiate' an object?
Explanation:
Instantiate an object means creating an instance of accessing the property of a class we can create instance or object for that class. The property of class means method and variable with the help of instance we can directly access the method and variable.
For example
class abc // class abc
{
public:
void sum1() // function definition
{
cout<<" hello "; // display hello
}
};
void main() // main method
{
abc ob; // creating an instance
ob.sum1(); // calling a function sum1
}
Output:
hello
Here we create a instance of class abc i.e ob which can access the method sum1().

Write a C++ program that will convert distance measurements from miles to kilometers. Specifically, the program needs to convert 0, 10, 20, 30, 40 , 50, 60, 70, 80, and 90 miles to kilograms displaying both the number of miles and the number of kilograms on the same line.
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// loop that will convert 0,10,20.....90 miles to kilometer
for(int a=0;a<=90;a=a+10)
{
// convert miles to kilometer
double kilo_m=a*1.609;
// print the result
cout<<a<<" miles is equal to "<<kilo_m<<" kilometer."<<endl;
}
return 0;
}

While the concept of ____ has well served scientists who share scientific text files and application developers who exchange code, the greater use has been in downloading artistic files, such as music and video files.
VPNs
LANs
point-to-point file protocol
peer-to-peer (P2P) file sharing
Answer: peer-to-peer (P2P) file sharing
Explanation: Peer-to-peer file sharing is the technique in which networking technology is used for the sharing and distribution of the files digitally. The sharing of the files are in the form of movies, games music etc.
Peer are considered as the nodes which are the end-user so, the end-user to end-user file transfer is done through this technology.
Other options are incorrect because VPN(virtual private network) is the connection between network and client over less secure network,LAN (Local area network) is the network that can be established for single infrastructure to connect and point to point protocol is protocol for the routers for communication.Thus the correct option is P2P file sharing.

How many bytes are there in 256 Kbytes?
Answer:
256000 bytes.
Explanation:
One Kilo byte(KB) consists of 1000 bytes.So the number of bytes in 256 kilo bytes is :-
1 kilobyte = 1000 bytes.
256 kilo bytes = 256 x 1000 bytes.
256 kilo bytes = 256000 bytes.
Also 1 bytes consists of 8 bits.
1 kb = 1000 bytes.
1GB Giga byte = 1024 kilo bytes.
1 TB Tera Byte = 1024 Giga Bytes (GB).
Hence the answer to this question is 256,000 bytes.
"What does the list look like after this code executes?
colors = "red,orange,yellow,green,blue"
s = colors.split(",")
["red", "orange", ""yellow", "green", "blue"]
["red orange yellow green blue"]
[red,orange,yellow,green,blue]
red
Answer:
The list created by the split method in Python 3 will be ["red", "orange", ""yellow", "green", "blue"]
Explanation:
In Python 3, the split method takes the input string, in this case is colors = "red,orange,yellow,green,blue", and split it into a list and you can indicate the separator that the method will use.
The general syntax for this method is:
string.split(separator,max)
separator indicates the character that will be used as a delimiter of each list member and the max parameter indicates the maximum number of separations to make.
Since each color in your string is separated by the character "," the code will make a list in which every color is a separated string.

Write a function called reverse() with this prototype:
void reverse(char dest[], char source[], int size);
Your function should copy all the elementsin the array source into the array dest, except in reverse order. The number of elements in the source array is give in the parameter size. Use a for loop to do the copying. Assume that dest is large enough to hold all of the elements. Please be thorough with commenting.
Answer:
void reverse(char dest[], char source[], int size)
{
for(int i=0;i<size;i++)//using for loop.
{
dest[i]=source[i];//assigning each element of source array to dest array.
}
int s=0,e=size-1;//initializing two elements s with 0 and e with size -1.
while(s<e){
char t=des[s]; //SWAPPING
dest[s]=dest[e]; //SWAPPING
dest[e]=t; //SWAPPING
s++;
e--;
}
}
Explanation:
I have used while loop to reverse the array.I have initialize two integer variables s and e with 0 and size-1.Looping until s becomes greater than e.
It will work as follows:
first s=0 and e=0.
dest[0] will be swapped with dest[size-1]
then s=1 and e=size-2.
then des[1] will be swapped with dest[size-2]
and it will keep on going till s is less than e.
