Front

An ad-hoc network allows two devices to communicate directly without the need for a router or wireless access point.

Back

Ad-hoc networks enable direct communication between devices.

Front

Tethering involves creating a personal hotspot on a device, such as a smartphone, for other devices to connect to and utilize its internet connection.

Back

Tethering is commonly used to set up ad-hoc networks.

Front

Personal Area Networks involve multiple devices connecting around a single individual, often set up as an ad-hoc network.

Back

Personal Area Networks are a type of ad-hoc network.

Front

Ad-hoc networks often utilize wireless methods like Wi-Fi or Bluetooth for communication.

Back

Wireless communication methods are common in ad-hoc networks.

Front

One simpler method of creating an ad-hoc network is through Tethering, where devices connect to a personal hotspot created by another device to access its internet connection.

Back

Tethering simplifies the creation of ad-hoc networks.

Front

An open Wi-Fi network is a hotspot that does not require a password for access and lacks encryption, making data transmission insecure.

Back

Open Wi-Fi networks pose security risks.

Front

Connecting to an open Wi-Fi network can expose your data to potential theft by anyone within signal range, who could intercept sensitive information like bank account details or passwords.

Back

Security risks are associated with open Wi-Fi networks.

Front

Users can protect their data on open networks by using encryption technologies like a VPN (Virtual Private Network) to secure their transmissions.

Back

Using a VPN helps protect data on open networks.

Front

Ad-hoc networks are decentralized networks where devices communicate directly with each other. They suffer from performance issues such as slower data transfer speeds compared to networks in infrastructure mode.

Back

Performance issues are common in ad-hoc networks.

Front

A major limitation of ad-hoc networks is their slower maximum data transfer speed compared to networks in infrastructure mode.

Back

Slower data transfer speeds are a limitation of ad-hoc networks.
