Answer:
eavesdropping
Explanation:
Eavesdropping is as an <em>electronic attack</em> where digital communications are intercepted by an individual whom they are not intended. This is done in two main ways: <em>Directly listening</em> to digital or analog voice communication or the <em>interception or sniffing</em> of data relating to any form of communication.
Answer:
C. receiving data.
Explanation:
An information system interacts with its environment by receiving data in its raw forms and information in a usable format.
Information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.
Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.
Additionally, an information system comprises of five (5) main components;
1. Hardware.
2. Software.
3. Database.
4. Human resources.
5. Telecommunications.
<em>Hence, the information system relies on the data it receives from its environment, processes this data into formats that are usable by the end users. </em>

Answer:
Option is b is correct answer. Excel performs exponentiation, then multiplication and division, then addition, and subtraction, it is correct order of operation in Excel. It is important to remember when you write any formula in Excel having different mathematical operators like +/ -/ ^/ etc, it follows a specific order and performs calculations in specific order which is termed as order of operator precedence. Each of mathematical operator has its precedence and executes in a special order set by Excel.
Explanation:
- As we already know order of precedence of each mathematical operator is different in Excel. The order of operations for Excel is as follows:
- Evaluate elements in parentheses.
- Evaluate 'ranges' ().
- Evaluate 'intersections' (empty spaces).
- Evaluate 'unions' (,).
- Perform negation (-).
- determine percentages (%).
- Perform exponentiation (^).
- Perform multiplication (*) and division (/), both are of equal precedence.
- Perform addition (+) and subtraction (-), both are of equal precedence.
- Evaluate text operators like (&).
- Perform comparisons like (=, <>, <=, >=).
