Answer:
sed '/march/{d;}' birthdays.txt > result
.txt
Explanation:
sed syntax is basically:
<em>sed '/expression/{command;command;...;}' inputfile > outputfile</em>
- First, for the expression part, we use /march/ to match all lines containing that string.
- Then for the command part, we only use {d} command to delete every matching line found.
- The third part contains the input file to process, I have named it birthdays.txt, but it could have been any other file needed.
- Finally "> result
.txt" makes the script output to be saved into a file named result.txt
The second factor as it did not make travel easy at all
Solution:
It is important because, it has to do operation on so without, data structures and algorithms.
It performs these operation:
1)Take an input
2) Process it
3) Give back the output.
The input can be in any form, for ex while searching for directions on google maps, the starting point and the destination as input to google maps, while logging in to any social sites, We have to give our email and password as input and so on.
Similarly, in the third step, the computer application gives us output in some form or the other.
To make this process efficient, we need to optimize all the three steps.
You are using a device that reads the physical addresses contained in incoming data that travels along network cables. Based on the physical address that it reads, the device then forwards the data out one of its ports to reach the destination device. The type of device you are using is router.
<h3>What is Router?</h3>
A router is an hardware device that is used in transferring information or data from a system to another.
The data can also be transfered from one computer networks to another.
Router makes it easier for more than one device to be connected easily without difficult Internet access.
Therefore, The type of device you are using that reads incoming data that travels along network cables is router.
