Dear Sir, Namaskar, ( confuse in No. 3 question’s answer)
3. The command to display the contents of a file fast.it
TYPE it fast
COPY fast.it CON
COPY CON fast.it
None of above
Answer should be: None of the above(Note: Copy con is used to make file, So correct answer should be TYPE, not COPY CON fast.it)
(((There is no question on 17 no)))
MCQ Sets says
Dear Chandra,
In fact, there is no command like COPY CON. In fact it is COPY command with CON as one parameter. As you know COPY command takes two parameters, source and destination:
COPY sourceFile destinationFile
eg. COPY CON ram.txt
When you enter COPY CON as command, the CON is simply the source.
Then, what does CON mean? It is simply the reference to console (the keyboard/monitor). In example command, you instructed computer to copy the text from console into a file named ram.txt in current location.
Now what happens if you type:
COPY ram.txt con
This command will mean that you gave instruction to copy text from ram.txt file into console. So this command will display the content of ram.txt file on the monitor.
So among the options given, COPY fast.it CON will display the content of fast.it file.
Regarding the empty question, I’ll check and try to correct it. Thank you for pointing it.
