Compression is used to save space or reduce bandwidth.
Lossy compression means you lose details of the information, but for some types of information that is not a problem. With lossy compression you will not be able to reconstruct the original data, but you'll get something that's 'close enough'. Examples of lossy compression are JPG images, MP3 files.
Lossless compression means you can reconstruct the original data without losing one single bit. You'll need this if the data can't afford to be changed, like a bunch of spreadsheets with financial data. A ZIP file is an example of lossless compression. But in audio you also have FLAC, a lossless compression format for audio geeks.
With lossy compression the amount of compression you can achieve is usually higher than with lossless compression, which is to be expected.

Technicans A says the engine camshaft converts reciprocating motion of the piston into rotary montion for power output. Technician B disagrees and says the crankshaft performs this function who is right?
It doesn't say what Technician B thinks, but I can tell you what the camshaft does and then you can decide who is right on your own. The camshaft is little metal rounded triangles above the piston that times when the intake and exhaust valve open and close.
Technician A is very wrong, the camshaft doesn't do that.
Final answer:
In a four-stroke internal combustion gasoline engine, both the crankshaft and camshaft play important roles in converting the reciprocating motion of the piston into rotary motion for power output.
Explanation:
In a four-stroke internal combustion gasoline engine, both the engine's crankshaft and camshaft play important roles in converting the reciprocating motion of the piston into rotary motion for power output.
The crankshaft converts the up-and-down motion of the piston into a rotating motion, which is then used to transfer power to the wheels of a vehicle or other devices.
The camshaft is responsible for opening and closing the engine's valves at the correct times, allowing for the intake of fuel-air mixture and the exhaust of combustion byproducts.

How do they make the "chips" in computers?
This is done using an optical process, not unlike how old photos were printed. A silicon wafer is covered with some etching resisting material, and then exposed to UV light through a mask. The mask is a drawing of the chip schematic.
The etching resisting material is removed where the light hits (or vice versa), and parts of the silicon wafer is etched away with a chemical. Different layers can be deposited by repeating this process.
Finally the wafer is cut into little rectangles and placed inside a housing.

Suppose there is a class Alarm. Alarm has two class variables, code which contains a String value representing the code that deactivates the alarm, and armed which contains a boolean describing whether or not the alarm is activated. Alarm has a function changeCode that takes two parameters containing Strings, the first representing the current code, and the second representing the new code. If the user inputs the current code correctly, the value of code is changed to that of the new code. Call the changeCode function on the Alarm object myAlarm, whose current code is "3456", and change the code to "7921".
it would be
myAlarm.changeCode("3456", "7921");
To change the code of the Alarm class, use the changeCode method by passing the correct current code and the new desired code.
For the instance myAlarm with the current code '3456', call myAlarm.changeCode('3456', '7921') to change the code to '7921'.
In programming, variables are placeholders in memory that can change their values. Here, we have a class Alarm with class variables code (a String) and armed (a boolean).
The changeCode method allows the code to be updated if the current code is inputted correctly. Assuming you have an instance of Alarm called myAlarm and its current code is "3456", you can change it to "7921" as follows:
class Alarm:After running this code, myAlarm.code will now be "7921".
