Explanation:
According to Equation
10.10, the angular speed must therefore vary as the laser–lens system moves
radially along the disc. In a typical CD player, the constant speed of the surface at
the point of the laser–lens system is 1.3 m/s.

The TCP/IP stack is responsible for the "chopping up" into packets of the data for transmission and for their acknowledgment. Depending on the transport protocol that is used (TCP or UDP) each packet will be <span>acknowledged or not, respectively.
</span><span>the strategy when the file is chopped up into packets, which are individually acknowledged by the receiver, but the file transfer as a whole is not acknowledged is OK in situations (Applications) that do not need the whole file to be sent, Web site for example: different parts of the web site can arrive in different times.
The other strategy, in which </span><span>the packets are not acknowledged individually, but the entire file is acknowledged when it arrives is suitable for FTP (mail transfer), we need whole mail, not parts of it. </span>

Explanation:
Execution step:
1. Starting the program
2. It will get the animal name
3. Check whether the animal eats only plants. Then it prints "Herbivore". If the condition is false, it prints "carnivore".
4. Stop the program
To identify input, output and decision:
Start and Stop (oval): These are neither input nor output
Does it eat only plants?: Decision making statement ("d")
Read the names of the animals(Parallelogram): Input ("i")
Print Herbivore, Print Carnivore: Output "o"
Scenario 1: Input is lion
1. Start
2. Reads the input as "lion"
3. Check if lion eats only plants. So here it is false
4. Print "Carnivore"
5. Stop
Scenario 1: Input is Elephant
1. Start
2. Reads the input as "Elephant"
3. Check if lion eats only plants. So here it is true
4. Print "Herbivore"
5. Stop
