Answer:
UTF-8 and ASCII both are the character encoding.
In a system,every character has some binary representation,these are the method to encode them.Earlier only ASCII was there, for every character it uses 8 bits to represent.In ASCII only 8 bytes were there i.e 2^8 that is 256.We can't represent number beyond than 127 so it generate a need for other encoding to get into,these drawbacks lead to Unicode,UTF-8.
As ASCII codes only uses a single byte,UTF-8 uses upto 6 bytes to represent the characters.So we can save characters which are as long as 2^48 characters. We can read this encoding easily by the help of shift operators and it is also independent of byte order.
As messages on internet were transferred over 7 bit ASCII messages,so many mail servers removed this encoding.
Answer:
This is how a magnetic hard drive works
Explanation:
The hard drive contains a spinning platter with a thin magnetic coating. A "head" moves over the platter, writing 0's and 1's as tiny areas of magnetic North or South on the platter. To read the data back, the head goes to the same spot, notices the North and South spots flying by, and so deduces the stored 0's and 1's.
Hope it helps pls mark as brainliest
Answer:
The solution code is as follows:
- #include <iostream>
- #include <fstream>
- #include <string>
- using namespace std;
- int main()
- {
- ifstream data;
- float number;
- float sum = 0;
-
- data.open("numbers.txt");
-
- while (data >> number) {
- sum = sum + number;
- }
- cout<<sum;
- return 0;
- }
Explanation:
Firstly, we create a ifstream object, <em>data</em> (Line 9). Then we can use the ifstream object to open the "numbers.txt" (Line 13) and use while loop to traverse through the number in the text file line by line (Line 15). White the loop is ongoing the number in each line is read by >> operator in a similar way to cin and then add each read number to sum variable (Line 16).
At last, display the output (Line 18).

A command you would use to perform a reverse lookup of the IP address 10.0.0.3 on a Linux system: dig -x 10.0.0.3.
<h3>What is a Linux command?</h3>
A Linux command can be defined as a software program that is designed and developed to run on the command line, in order to enable an administrator (end user) of a Linux network perform both basic and advanced tasks by only entering a line of text.
<h3>What is IP address?</h3>
IP address is an abbreviation for Internet protocol address and it can be defined as a unique set of numbers that are assigned to a computer, website or other network devices, in order to successfully differentiate them from one another in an active network system.
In Computer Networking, a command which an administrator (end user) would use to perform a reverse lookup of the IP address 10.0.0.3 on a Linux system is dig -x 10.0.0.3.
