Stderr is 2. stdin is 0, stdout is 1.
Answer: D)The pattern of blood vessels at the back of the eye.
Explanation: The retinal scan is the techniques which is used in the bio-metric mechanism.The scanning of the retina's blood vessel pattern is capture by the scanner is the unique technique which is used for bio-metric purpose.
Blood vessel pattern is capture because it is present in unique form for every person and will help in distinguishing a person from another person while scanning.
Other options are incorrect because light reflection or reaching near retina and light pattern are not the unique way for identification while scanning a person.Thus the correct option is option(D).
Answer:
Given,
P = (22, 1, 42, 10)
Q = (20, 0, 36, 8)
a. Formula for Euclidean Distance :
distance = ((p1-q1)^2 + (p2-q2)^2 + ... + (pn-qn)^2)^(1/2)
Now,
distance = ( (22-20)^2 + (1-0)^2 + (42 - 36)^2 + (10-8)^2) ) ^(1/2)
=( (2)^2 + (1)^2 + (6)^2 + (2)^2 ) ) ^(1/2)
=(4+1+36+4)^(1/2)
=45^(1/2)
Distance = 6.7082
b.Manhattan distance :
d = |x1 - x2| + |y1 - y2|
d = |22- 20| + |1 - 0|
d = |2| + |1|

Answer:
In a bumper-to-bumper traffic, when the engine starts overheating the situation can be handled by tapping the accelator which will revive the engine.
Explanation:
Overheating of engine can be due to many reasons. But one should know what to do when an engine overheats in a traffic. Bumper-to-bumper traffic is when the cars are so close in traffic that they touch each other. This usually happens when there's a traffic for a long time or on very busy lane. During summer times, it is important to keep checking the engine temperature to avoid any problem.
When one is stuck in bumper-to-bumper traffic with overheating engine, then there are some meausres that one can take. They are:
- To put the car on park or neutral mode of driving and tap the accelator which will revive the engine.
- The heat can be disperse by rolling down the window and turn the heater up. It will disperse the heat.
Answer:
A. Run the parted command.
D. Reboot the system.
Explanation:
Linux command line shell is a vital tooling server administration. It provides the flexibility of executing user and kernel mode commands on the command line interface.
Unlike graphic user interface operating systems, it receives typed commands on its prompt to execute tasks. The fdisk command shows the newly created partition on a disk, and to reload, the parted command is executed or the system should be rebooted.
