The travel agents must be able to conduct business from their office building or by using their mobile office - NSC Information Technology - Question 6 - 2017 - Paper 2

1. Data input can be challenging due to the small screen size, which may lead to errors and inefficiency.
2. Limited battery life can disrupt workflows, especially if phones are not charged regularly.

Online syncing services such as Google Drive or Dropbox allow travel agents to access the latest versions of their documents on all devices.

1. Biometric scanners that use fingerprints or facial recognition for authorized entry.
2. RFID cards that must be scanned to gain access.

AUP stands for Acceptable Use Policy.

1. Policy on using personal devices within the workplace.
2. Guidelines on acceptable internet usage to prevent security breaches.

1. Social networking can lead to distractions, reducing overall productivity in the workplace.
2. It may expose the company to security risks, such as the theft of sensitive information through unauthorized sharing.

An intranet is a private network accessible only to an organization's staff, often used to share information and resources securely.

Travel agents could log on to a VPN (Virtual Private Network) to securely access the agency's intranet from home.

The NIC (Network Interface Card) allows a computer to connect to a network, directing data to and from the device.

A MAC address serves as a unique identifier for a network interface, ensuring that data is correctly routed to the appropriate device.

Travel documents can be captured using a digital camera or smartphone to take photos and upload them directly to the system.

1. Improved management of devices ensures that resources are used efficiently.
2. Enhanced communication between connected devices allows for quick data sharing.

Wireless technologies such as Wi-Fi or Bluetooth would enable a user to print on the printer without being connected to a cabled network.

A web browser that supports cloud-based interfaces is needed to run cloud applications.

1. SaaS eliminates the need to purchase software licenses, reducing upfront costs.
2. It provides access to the latest software versions and updates without manual installations.

Cloud computing utilizes virtualization by allowing multiple users to share powerful server resources simultaneously, making it more cost-effective and scalable.

1. Cloud services require a stable internet connection; disruptions can lead to accessibility issues.
2. Data security concerns arise as sensitive information is stored off-site.

Encryption is a process that transforms data into a secure format, making it unreadable to unauthorized users, thereby ensuring confidentiality during transmission.

Public key encryption uses a pair of keys: a public key to encrypt data and a private key to decrypt it, ensuring secure communication between parties.

One disadvantage is that transactions made with Bitcoin cannot be cancelled or reversed, leading to potential loss if mistakes occur.

BitTorrent is a peer-to-peer file sharing protocol that allows users to distribute data over the internet efficiently.

1. It allows for efficient sharing of large files across a network without putting too much load on any single server.
2. Many users can download popular files quickly, as the workload is distributed among multiple peers.

1. Downloading software that is available under a free license or as freeware.
2. Downloading shareware versions that are explicitly offered for trial purposes.
