IT AWARENESS QUIZ

Answer to this is: DMA mode of data transfer.

Whenever, DMA mode of data transfer is initiated DMA controller sends DMA request to processor, after receiving it processor sends DMA acknoledgement to DMA controller, after it DMA controller sends HOLD signal. So after receiving HOLD signal Processor relinquishes the control of Address bus and Data bus.

awesome man!! absolutely correct answer and the working of the DMA transfer sequence.

Time for the next question:

It is used as a trap door to sneak into OS’s information.
It is generally used to capture the password and login information.
It does not replicate.

what's its name?
 
Plz give some more clue, I think it might be any software like password recovery, which is used to hack the password. or we can say it HACKER in broad sense.

it can't be a hacker buddy... see the 1st hint... think a little... its very easy.
 
It remains resident in the memory in a dormant state, doing nothing other than occupyiny the memory.

It is activated by hitting the appropriate hotkey.

It steals the normal keyboard interrupt by replacing the address in IVT with the address of one of its routines.

The response is pretty bad... :( Need some more active response here.

The answer is TSR (terminate and stay resident)
- program which is located in a computer's memory and may be operated by pressing a combination of keys
 
Ok, the next question... this should be supposedly easy...


It is an open source software.

It is platform independent.

It can be used to create programs that can execute from WWW pages.

Very good Keshwendu... correct answer. It is an open source, platform independent language used for web designing.
 
Now let's try 2 questions....

1)
It is a stored procedure that can be used by RDBMS.

It is automatically executed whenever a specified table is updated.

It works similar to an ASSERTION.


2)
It allows the instruction sequence in a multitasking system to switch from one stream to another.

After any disk operation the processor gets notified.

It causes the processor to suspend its current task and respond to the event.

Again not confirm but for
1) it is LINK LIST type procedure of storing database.
2) Interrupt
 
Now i'll be posting some questions from the hardware section..... Lets see who or how many can answer... :smile:

Very good keshwendu !! Almost close... Its called "Memory Protection Fault"

Okay next Question:

This one should be supposedly be very easy. The part of the hard disk that differentiates between primary master and primary slave ?

Actually i m doing B.E. in electronics and telecommunication so i have some idea of computer also. no any other qualification. Also in my answer i m doubtful.

No mate, ur answer is correct.... :smile:

Let's see if u can crack this one !!

The main processor bus connecting the CPU to the RAM ?

Thanks again...

Answer to this question is: CPU and RAM is connected through the Address Bus and Data Bus. Both address and data bus are time multiplexed to each other means that the same single bus carry address and data both but in different time.
