Bus topology: A network design where each computer and network device are connected to a single cable or backbone. In this topology, information sent from a device moves in both directions along the backbone until it reaches its destination device. If the backbone fails, the entire network becomes unusable, highlighting the importance of regular checks and maintenance in these setups. Despite this drawback, bus topology is appreciated for its simplicity and cost-effectiveness, especially for small networks.

BYOD (Bring Your Own Device): A corporate policy allowing employees to use their personal electronic devices for work-related tasks. This approach can increase flexibility and employee satisfaction but also introduces security implications. Personal devices may not have the same stringent security controls as company-issued hardware, potentially exposing the network to malware or data breaches. To mitigate risks, businesses often implement BYOD security policies that include the use of VPNs, mandatory antivirus software, regular security updates, and the compartmentalization of company data through containerization or secure applications. These measures aim to safeguard sensitive information while accommodating the convenience of using personal devices.
