1. Items can be tracked efficiently, allowing for better inventory management and loss prevention.
2. RFID tags do not require a direct line of sight to be read, enabling quicker and more convenient scanning.

A network administrator is essential to manage and maintain the network infrastructure, ensuring that all devices are connected, performing efficiently, and secure from outside threats. Their role includes troubleshooting any issues that arise, maintaining network performance, and overseeing user access.

1. Passwords should include both uppercase and lowercase letters to increase complexity.
2. Passwords must include special characters (e.g. !, @, #) to further enhance security.

1. Remote Desktop Protocol (RDP): This allows users to connect to a remote computer via the internet, enabling them to control the system as if they were physically present.
2. Virtual Private Network (VPN): A VPN provides a secure connection to the network through encrypted tunnels, allowing safe access to resources remotely.

To safeguard the computers against virus attacks, the administrator should install reputable antivirus software and ensure it is regularly updated. Keeping the operating system and all software up to date is also crucial in protecting against vulnerabilities.

1. Allocating user rights: This involves setting up permissions for different users in order to protect sensitive information.
2. Managing backups: Regularly performing backups of data ensures that critical information is not lost in case of hardware failure or other issues.

Spam e-mail refers to unsolicited messages sent in bulk, often intended to advertise products or services. These emails can clutter inboxes and sometimes lead to phishing scams.

1. Use strong passwords and change them regularly to protect personal information.
2. Avoid sharing personal details on social media and be cautious about the information provided on unfamiliar websites.

The technique used to ensure that Skype calls are secure is encryption, which protects the communication data from eavesdroppers.

A digital certificate is used to authenticate the identity of a website or organization, ensuring that users are connecting to legitimate entities to prevent fraud or impersonation.

1. Check whether the author of the information is reputable, such as looking for qualifications or affiliations.
2. Compare the information with that found on multiple reliable sources to verify its accuracy.

The Internet of Things (IoT) refers to the interconnected network of devices that can communicate and exchange data over the internet. These devices include everyday objects like smart home appliances, wearables, and vehicles, allowing them to collect and share data to improve efficiency or user experience.

1. Users can reduce screen brightness or set the device to automatically adjust brightness to conserve battery life.
2. Disabling unnecessary features like GPS, Bluetooth, and Wi-Fi when not in use can significantly extend battery longevity.

A rootkit is a collection of software tools that allow an unauthorized user to gain control over a computer system without being detected. It can manipulate the system to hide its presence and enable further exploitation.

BitTorrent operates over a peer-to-peer network, allowing users to distribute data across multiple nodes efficiently, rather than relying on a single source.

One disadvantage of using BitTorrent is that it can expose the IP address of users, making their internet activity potentially traceable.

Using a file-sharing service can accommodate larger files that exceed email size limits. Additionally, it allows for real-time collaboration and version control, enabling multiple users to access and edit the document simultaneously.

1. Automatic syncing: All changes made to files are reflected across devices without user intervention.
2. Version history: Users can access previous versions of files, ensuring that work is recoverable.
3. Access from anywhere: Files can be accessed remotely, enhancing flexibility.

1. User interface simplicity: The app should have an intuitive design that is easy to navigate on smaller screens.
2. Performance optimization: It is crucial to ensure the app runs efficiently without draining device resources.
3. Security: Incorporating strong security measures is vital to protect user data and privacy.
