Answer:
Option c: Heuristic
Explanation:
Heuristic scanning is a form of computer virus detection analysis that screen for the suspicious characteristic of the program which maybe a virus. Heuristic scanning is designed to detect those new computer virus, unknown virus or the modified version of the known virus.
To perform heuristic scanning, a weigh-based evaluation algorithm will be adopted to estimate the likelihood of the current scanned program behaves like a virus which can pose a computer threat. If it exceeds a threshold level, an alarm will be triggered.
Answer:
Option c is the correct answer for the above question.
Explanation:
A loop is used to repeat some lines in some specific times which depends on some conditions of the loop. If a person wants to print "welcome" on 5 times then he can do this by two ways one is writing a print statement 5 times and the other is states a loop that executes 5 times through condition. The loop is described or written by three necessary points which are:-
- The fist is to initialize the initial value which tells the compiler for the starting point of the loop.
- The second is to any action for that condition variable which takes the loop for the direction of ending points.
- The third is a condition that defines the ending point of the loop.
The above question also states about the loop in which first and second points are given then the third point is necessary to complete the sentence which is states in option c. Hence the option c is correct while the other is not because--
- Option 'a' states about the class operator which is not the part of the loop.
- Option b states about the documentation plan which is also not the part of the loop.
Answer:
RTT1+ RTT2+..... RTTn
Explanation:
The total estimated time to get the IP address is
RTT1+ RTT2+..... RTTn
Once the IP address is known, O RTT elapses to set up the TCP connection and another O RTT elapses to request and receive the small object. The total response time is
2RTT0+RTT1+RTT2+.....RTTn
Answer:
1. Insufficient storage space
2. Blue screen of death
3. Virus intrusion
4. Overheating
5. Stiff keyboard keys
Explanation:
When using a computer system there are certain issues that users would most likely encounter. Some of them include;
1. Insufficient storage space. This could arise because of insufficient storage in the hard drive or because the computer has limited memory space. Users might be unable to download apps because there is no space for them.
2. Blue screen of death. This occurs when the computer suddenly displays a blue screen with some information on the likely reason for the malfunction. A common cause of it is the use of corrupt devices.
3. Virus intrusion. This occurs for several reasons. It could be the result of a corrupt device, document, or application that was introduced to the computer. This could make the device to work at a slower rate.
4. Overheating. This usually occurs when the parts responsible for keeping the computer at a cool temperature malfunction. The system can crash suddenly as a result of this problem.
5. Stiff keyboard keys. Some buttons could become suddenly stiff and unable to function properly.
