Which of the following can be used to locate data in a particular column?

dangina [55]

Answer:

A. VLOOKUP

Explanation:

VLOOKUP is an Excel function to look up data in a table organized vertically. VLOOKUP supports approximate and exact matching, and wildcards (* ?) for partial matches. Lookup values must appear in the first column of the table passed into VLOOKUP.

Purpose

Lookup a value in a table by matching on the first column

Return value

The matched value from a table.

Syntax

=VLOOKUP (value, table, col_index, [range_lookup])

Arguments

value - The value to look for in the first column of a table.

table - The table from which to retrieve a value.

col_index - The column in the table from which to retrieve a value.

range_lookup - [optional] TRUE = approximate match (default). FALSE = exact match.

Programming challenge description: Write a program that, given two binary numbers represented as strings, prints their sum in bi

Lubov Fominskaja [6]

Answer:

The program to this question can be given as:

Program:

#include<iostream> //include header file

using namespace std;

string add(string a, string b) //define add function

{ //declare variable

string result = "";

int sum = 0,k,l;

cahr x;

k= a.size() - 1;

l = b.size() - 1;

while (k>= 0 || l>= 0 || sum == 1) //loop

{

//addition

sum= sum+ ((k >= 0)? a[k] - '0': 0);

sum= sum+ ((l >= 0)? b[l] - '0': 0);

x=sum%2;

result=(x+'0') +result;

// Compute carry

sum =sum/ 2;

// Move to next digits

k--;

l--;

}

return result; //return value

}

int main() //main method

{

string a,b; //string variable

cout<<"Enter first binary digit: "; //message.

cin>>a; //input from user

cout<<"Enter Second binary digit: "; //message.

cin>>b; //input from user

cout <<"Addition :"<<add(a, b)<<endl; //print addition

return 0;

}

Output:

Enter first binary digit: 1101

Enter Second binary digit: 100

Addition :10001

Explanation:

In the above c++ program first, we include the header file. Then we define the add function in the add function we add two binary digits by passing value as arguments. In this function, we define a variable that is used on the addition of binary numbers. In this function we define the loop in the loop we check if two binary number is 1 then it will print 0 and pass 1 as the carry. after performing addition it will return value. In the main function, we take two binary numbers from the user and pass the value to the function and print function return value.

MakcuM [25]

A network administrator notices that some newly installed Ethernet cabling is carrying corrupt and distorted data signals. The new cabling was installed in the ceiling close to fluorescent lights and electrical equipment

Two factors may interfere with the copper cabling and result in signal distortion and data corruption are :

EMI

RFI

Explanation:

EMI (electromagnetic interference) is the disruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device.
During EMC testing, radiated emissions measurements are made using a spectrum analyzer and or an EMI receiver and a suitable measuring antenna.
EMI (Electromagnetic Interference) is also called RFI (Radio Frequency Interference).
Conducted RFI is unwanted high frequencies that ride on the AC wave form. Radiated RFI is emitted through the air. There are many pieces of equipment that can generate RFI, variable frequency drives included.
The internal circuits of personal computers generate EM fields in the RF range.

Ket [755]

Answer:

A. 4 CPUs and 6 megabyte cache memory

B. 1.3157 x10^-9 nanoseconds

Explanation:

The Intel core i5 7500 is a seventh generation central processing unit with a 4 CPU core and a 6 megabyte cache memory. It executes task at a clock cycle of 5 clock cycle at a speed of 3.8 GHz.

The relationship between frequency and clock cycle is,

Clock cycle = 1 / ( frequent).

So, One clock cycle = 1 / 3.8 GHz

= 0.3 x10^-9

For five clock cycles = 5 x 0.3 x10^-9

= 1.3157 x10^-9 nanoseconds.
