What are database systems?</h3>
Database is a collection of related data stored in a manner that it can be retrieved as needed. Database system or Database Management System (DBMS) are enables us to create, maintain, and access databases. A database typically consists of Tables, Fields (columns) and Records (rows).
Advantages of DBMS approach are low level of redundancy, faster response time, lower storage requirements, easier to secure, increased data accuracy. Disadvantage of DBMS approach is increased vulnerability (backup is essential).

#SPJ4
<span>1. The RGB value 0 is equal to "FF" in the HTML color code.
</span><span>False
The 0 value in RGB is expressed as "00" which was 15*0+0= 0. The "FF" value would be 15*16 + 16.
2. HTML color codes are made up of numbers 0-15.
False
HTML color codes are made up by hexadecimal which was number 0-9(10 number) and letter A-F(6 letters) which sum up to 16 combinations in total. The number A-F will be equal to 11-16 respectively.
</span><span>
3. What color is defined by the bold numbers? #991F8C (99 is bold)
a. red
RGB stands for red green blue which was the order of the code of the color. The color code is made of 6 digits of number or letter with each code getting the 2 digits. From </span>#991F8C, 99 is the first two digits that represent the Red value.<span>
4. The color #2P0000 contains no amount of green or blue.
True.
In </span>#2P0000, the value of red would be "2P", the value of green would be "00" and the value of blue would be "00". The color-coded only have red color so it should be red.
<span>
5. What color is defined by the bold numbers? #991f8c (8c is bold)
c. blue
</span>RGB stands for red green blue which was the order of the code of the color. The color code is made of 6 digits of number or letter with each code getting the 2 digits. From #991F8C, 8C is the last two digits that represent the Blue value.
<span>
6. The color #450045 has equal amounts of red and blue.
</span>In #450045, the value of red would be "45", the value of green would be "00" and the value of blue would be "45". The color should have the same amount of red and blue without green color<span>
7. Of which of the following is #323232 an example?
c. HTML color code
The code should be </span>HTML color code since it uses "#" symbol and then 6 digits of numbers. RGB color model would look like <span>(255, 0, 0)
</span><span>It's a bit ambiguous though since the </span>HTML color code is using hexadecimal but HTML color code would be more specific.<span>
8. In the RGB color model, what do the numbers 0-255 represent?
b. the intensities of each color beam
The number should represent the intensity of each color. The higher the number, the higher the intensity would be.
9. The color #ff1700 contains no amount of green.
False
</span>In #ff1700, the value of red would be "ff", the value of green would be "17" and the value of blue would be "00". The color should have no amount of blue color since the value is "00". The color still have green value of "17"
<span>10. The color #5d5d45 has equal amounts of red and blue.
False
</span>In #5d5d45, the value of red would be "5d", the value of green would be "5d" and the value of blue would be "45". The color should have the same amount of red and green value, not red and blue.
Answer:
True
Explanation:
In order to be able to run a webpage successfully, there are various coding and formatting that are required and can considered necessary.
They are:
a) Hypertext Transfer Protocol(HTTP): This is a protocol that is made use of on webpages. It is used to determine the information or data that is collected and transmitted through webpages. The commands that are programmed on webpages are modified by this protocol. The data or information that can be transmitted using HTTP includes: Pictures, Video or Audio recordings e.t.c.
b) Hypertext Transfer Protocol Secure(HTTPS) : This is an advanced or modified form of HTTP. The difference between them is HTTPS is more secure than HTTP. HTTPS is defined as a more secured protocol thorough which data or information can be transmitted from one webpage to another. HTTPS make used of an encrypted type of security during data transmission.
c) Cascading Style (CSS): It is a computer language technology that helps to define and modify the way a webpage looks like. Cascading Style can be defined as a formatting style that deal with the fonts, colour , layout of a webpage.
d) JavaScript :This is a programming language that is used on webpages. It is a set of coding that has commands embedded insided that is written to make webpages more interactive and fun for the users of the Internet.
e)Hypertext Markup Language (HTML): This is what is used to create webpages on the internet. Hypertext Markup Language defines what a webpage actually looks like which involves, the written document on the webpage
