1. D. cyber venting

Cyber-venting is the act of bad-mouthing about one's employer, senior executives, colleagues, etc. with the intention of letting off the steam, using websites and making such comments public for all to see them.

2. B. poor recall

(3)

A system with high precision but low recall is just the opposite, returning very few results, but most of its predicted labels are correct when compared to the training labels. An ideal system with high precision and high recall will return many results, with all results labeled correctly.

For example, for a text search on a set of documents, recall is the number of correct results divided by the number of results that should have been returned. In binary classification, recall is called sensitivity. It can be viewed as the probability that a relevant document is retrieved by the query.

3. C. value added networks

A value-added network (VAN) is a private, hosted service that provides companies with a secure way to send and share data with its counterparties. Value-added networks were a common way to facilitate electronic data interchange (EDI) between companies.

Types of Value-Added Networks

There are three types of VANs, based on how the computers in the network are connected:

1. One-to-One

The one-to-one network is a connection between two businesses exchanging data.

2. One-to-Many

A single business connected to multiple other businesses, e.g., a major retailer connected to its different suppliers.

6. 3. Many-to-Many netsetpreparation.com

Multiple businesses connected to one another. This is the most common type of network used in the financial markets since there are many market participants connected to each other via a single venue.

Benefits of VANs

Value-added networks enable electronic communication between businesses, taking advantage of available technological benefits, as listed below:

1. Error correction

VANs help in error correction, as they reduce human involvement, and improve recordkeeping. They can perform checks at the transaction level and ensure minimal error.

2. Improved exchange

The exchange of data becomes real-time with VANs. This improves decision-making and record-keeping and provides essential business intelligence to generate insights about operations.

3. Secure

Electronic data transfers can be made securely using encryption. All communication between businesses can be encrypted to protect business secrets.

4. Standardized

VANs transfer data using standard formats, such as XML and CSV. They allow the data to be read by the various Enterprise Resource Planning (ERP) software used by companies. They also enable the use of newer technologies without making changes to existing technology.

4. B. voice line

Voice-over-Internet Protocol (VoIP) is a technology that lets users make calls using a broadband Internet connection instead of a standard phone line. VoIP technology converts the voice signal used in traditional phone calls into a digital signal that travels via the Internet rather than analog phone lines. netsetpreparation.com

5. C. real-time video

The transmission of live video. It implies that there is no delay at the receiving side, or at most, imperceptible delays. Although a video broadcast that is streamed live may be considered real-time video, there is an intentional, buffered delay at the receiving end.
