Explanation:
A binary number is converted to hexadecimal number by making a group of 4 bits from the binary number given.Start making the group from Least Significant Bit (LSB) and start making group of 4 to Most Significant (MSB) or move in outward direction.If the there are less than 4 bits in last group then add corresponding zeroes to the front and find the corresponding hexadecimal number according to the 4 bits.For example:-
for this binary number 100111001011011.
100 <u>1110</u> <u>0101</u> <u>1011</u>
There is one bits less in the last group so add 1 zero(0) to it.
<u>0100</u> <u>1110</u> <u>0101</u> <u>1011</u>
4 E 5 B
100111001011011 = 4E5B
101011.1010
<u>0010</u> <u>1011</u> . <u>1010</u>
2 B A
=2B.A

Explanation:
Downloading of files without your permission is a form of security threat and attack. You as unwilling victim will have your files and private information stolen.
One of the basics of internet security is to terminate any connection that you have in a network to stop the possible attack or threat. Worst case scenario is we can shut down our computers or devices or gadgets. But if we can just terminate the connection without performing a force shut down on the device, it is much better. This will give us more time to save what we are working on and to prevent losing important works or data. Terminating the connection from the network comes in various activities such as:
*Disconnect from the internet - this is one of the most effective method. As most of the attacks are coming from external threats such a hacking.
*Closing the browser - this could be helpful as well. Hackers are using browser to monitor their victims. And malwares and adwares are most active while we use browsers as they are embedded and using it to propagate to peform their activities.
*Disconnect from the local network - if you have closed the internet connection and any active software that you are working on presently and the downloading of files still persists, probably the attack comes from your local network. You must close any connection that you have within the local network.
*Deleting the recent files you have downloaded - You must delete any recent files that you just downloaded from your email or from the internet. There might be malware embedded in the file. Malwares are used by hackers to get in to their victims computer without them knowing it.
Then after terminating all the connections, you must call on your Instructor's attention. He / She is the authority in charge and must be aware of the situation.
