The operating system (OS) of an information system contains the software that executes the critical functions of the information
Feliz [49]

Answer:

a. True

Explanation:

An information system (IS) 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.

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

On a related note, the software application that executes the critical functions of an information system (IS) are contained in its operating system (OS).

Basically, the computer's memory, processes, softwares and hardwares are typically being managed by the operating system (OS). Thus, an OS makes it possible for different programs to run simultaneously (more than one software program running concurrently) and access the computer's memory, central processing unit (CPU), and storage.

What is wrong with each of the following?
ankoles [38]

Answer:

The answer to this question is given below in the explanation section

Explanation:

shoNum + shoNum2 = shoTotal

in this code statement,  the order of operation is wrong because the calculation in programming always done at the right side of dependent variables.  so the correct statement of code is

<em> shoTotal = shoNum + shoNum2;</em>

shoNum = 10 * 4

This statement is programmatically correct, because the ShoNum value becomes 40 after performing the multiplication operation on its assigned value  (10 multiply by 4). However, it is noted that the empty space mostly ignored by the compiler. So, the correct is <em>shoNum = 10*4;</em>

Dim decPrice As Decimal = "$4.99"

The dollar sign is appeared in along with its value. So, if you assign value to a decimal variable, you need to assign only digit value (do not mix value with symbol or text) and also do not put quotation marks around value, if you put quotation marks around value then this value will be consider as a text value.

So, the correct statement is :

<em>Dim decPrice As Decimal = 4.99;</em>

shoCube= (shoSide)3

In this statement, cube is calculated of shoSide variable, mathematically it is right, but programmatically it is incorrect. Because, you missed the multiplication operation (*) between the operand shoSide and 3. it should

be as  shoSide raise to power 3.

the correct statement is : shoCube = (shoSide * shoSide *shoSide);
