Virtual Private Network (VPN) =] Detailed Explanations  1. Personal Area Network (PAN) A PAN is the smallest and most basic type of network, designed for personal use in a small area, typically within a range of a few meters. Examples include Bluetooth connections between a smartphone and a wireless headset or a laptop and a printer. - **Key Features**: Short range, personal use, typically wireless. - **Applications**: Connecting personal devices like smartphones, tablets, and laptops. #### 2.

five computer generations There are five computer generations known till date. Each generation has been discussed in detail along with their time period and characteristics. In the following table, approximate dates against each generation has been mentioned, which are normally accepted.   First generation computer:- The first generation of computers is generally known as electromechanical computers or using vacuum tubes. For example, ENIAC has used Vacuum tubes, relied on Machine Language and Boolean logic. A computer using vacuum tubes is very slow in executing programs compared to present-day computers.   Second generation computer :- The second generation of computers is a term used to describe a group of computers that were developed in the late 1950s and 1960s. These computers replaced vacuum tubes with transistors. Thus, making them smaller, faster, and more efficient. Third generation computer:- Third-generation computers used integrated circuits in place of ...
