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

One disadvantage is that it can be difficult to input data on a small screen, which may slow down workflow. Another disadvantage is that the battery life of smartphones can be limited, requiring regular charging, which can be inconvenient during long working hours.

An online synchronization service, such as Google Drive or Dropbox, is used to ensure that travel agents will have access to the latest versions of their documents on all devices.

Two methods the agency can use include biometric scanners, which can authenticate users based on physical characteristics, and RFID cards, which can grant access when scanned at entry points.

AUP stands for Acceptable Use Policy.

The AUP should include guidelines on what storage devices may be used and what actions will be taken against violations of the policy.

One reason is that social networking can serve as a distraction, reducing employee productivity. Another reason is that it can consume bandwidth, which may affect the performance of company operations.

An intranet is a local private network that is only accessible to the organization’s members and can be accessed through a browser as webpages.

Travel agents could gain access by logging onto a VPN (Virtual Private Network), which would encrypt their connection and protect data while accessing the intranet remotely.

The NIC, or Network Interface Card, allows a computer to connect to a network, facilitating the sending and receiving of data.

The purpose of a MAC address is to uniquely identify a device on a network, ensuring that it can communicate with other devices without conflicts.

Another way to capture travel documents as images is by using a digital camera or smartphone to take photos of the documents.

Networked devices allow for centralized data management and improved communication among multiple users in the office.

Bluetooth technology will allow a user, not connected to a cabled network, to print on the printer.

A web browser is needed to run cloud applications, allowing users to access cloud-based services and applications.

Two advantages of using SaaS include that it can be installed on multiple devices and that updates are done automatically to ensure users have the latest version.

Cloud computing utilizes virtualization by allowing multiple users to share resources on a virtual server. This means that the resources of powerful computers are distributed to provide services effectively.

Two disadvantages of cloud computing are the dependency on a stable internet connection and the fact that data security can be a concern since it is stored off-site.

Encryption refers to the process of converting data into a coded format, making it unreadable to unauthorized users and ensuring that only those with the key can access the original information.

The public key encryption method involves using a public key to encrypt data and a private key to decrypt it. The public key can be shared openly, while the private key is kept secret.

One disadvantage of using BitCoin is that transactions cannot be reversed, making it difficult to dispute or recover funds if an error occurs.

BitTorrent is a peer-to-peer file sharing protocol used to transfer large files across a network or the Internet efficiently.

Two benefits of using BitTorrent are that many users can download large files concurrently, which reduces the load on any single server, and it allows users to be part of the distribution process, making the download process more efficient.

Downloading software will not be regarded as piracy when it is obtained from the original publisher as freeware, or when it is downloaded as part of a trial period provided by the software developer.
