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:
SQL queries
The command used to display the customer ID and total number of orders placed is given below
Query:
SELECT CustomerID, COUNT (orderID) AS TotalOrders
FROM Order_Table
GROUP BY CustomerID
Explanation:
SQL queries
The command used to display the customer ID and total number of orders placed is given below
Query:
SELECT CustomerID, COUNT (orderID) AS TotalOrders
FROM Order_Table
GROUP BY CustomerID
SELECT - To query the database and get back the specified fields SQL uses the select statement
CustomerID is a coloumn name
The function COUNT(OrderID) returns the number of orders
Totalorderds is a label
FROM - To query the database and get back the preferred information by specifying the table name
Order_Table is a table name
GROUP BY - The clause is used to group the result of a SELECT statement done on a table where the tuple values are similar for more than one column
The table below displays the CustomerID and total number of orders placed
CustomerID Totalorders
4 28

Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is d- 346px.
The complete code of this example is given below:
<div>
style="margin:20px; border:solid 3px #888888;">
</div>
while the image width is 300px.
It is noted that the image width is 300px and the margin is 20 px.
Margin:20px means that image margin from four side is 20 px each.
So the width of dive from both side increase to 40 px and the image has 300 px, then total width becomes 340px. Now the border also has 3px of four sides of the image, then the width of the border becomes 6px.
so the total width of the div tag is 346 px.
In short, we can calculate the width of tag as below:
total width of div= width of image+ width of margin+ width of border
total width of dive= 300px+40px+6px
total width of div=346px.
A computer network is a group of computers that use a set of common communication protocols over digital interconnections for the purpose of sharing resources located on or provided by the network nodes.
Answer:
1GL: Machine language. Represented by a series of 1s and 0s.
2GL: Assembly language. An assembler converts 2GL into machine language.
3GL: High-level programming language. Uses a compiler to convert into machine language.
4GL: Specifically designed for creating database management programs.
5GL: Extremely advanced. Uses statements (scripts) rather than algorithms.
Explanation:
Programming languages started as a series of binary digits (i.e. 0's and 1'). This generation of language is referred to as the first generation.
However, the machine language were difficult to read by human, so mnemonics were created (i.e. assembly language). This language uses symbolic codes such as ADD for addition, etc. This is the second generation
The third generation are the high level languages that uses languages that can be easily understood by human, e.g. + means plus. However, the language must be translated; hence the need for a compiler or interpreter, as the case may be.
The fourth and fifth generations are extensions of the third generation languages. The fourth were created to connect to DBMS while the fifth are more advanced.
