• UDP does not establish a connection and does not guarantee delivery.

• TCP is used for applications like web browsing, email, and file transfer.

• UDP is used for real-time applications like video streaming and online gaming.

Encapsulation, Inheritance, Polymorphism, Abstraction

• Encapsulation: Bundling data and methods that operate on the data into a single unit

• Inheritance: Ability of a class to inherit properties and behavior from another class

• Polymorphism: Ability to present the same interface for different data types

• Abstraction: Hiding the complex implementation details and showing only the necessary features

Resistance rating can be measured from colour code by identifying the colour bands and their corresponding values.

• Identify the colour bands on the resistor, typically there are 4 or 5 bands.

• Refer to a resistor colour code chart to determine the value of each colour band.

• The first two bands represent the first two digits of the resistance value, the third band represents the multiplier, and the fourth band represents the tolerance.

• For example, a resistor with colour bands of b...read more
