What!!!!!!!!!!!!!!

What is weight?
Weight is the force of pull exerted on a body acting due to Gravity.
Advantages of friction plz
It helps in lighting fires ( using matchsticks)
It enables organisms to move from one place to another (locomotion)
it enables the sharpening of tools such as knives, saws and swords\blades.
It enables electrostatic charging of some materials
State 2 types of bonds
Covalent bond ( Btn non metals, such as 2H+O------->H2O )
Electrovalent\Ionic bond ( Btn metals and non metals, such as Na+Cl-------------->NaCl)
From, M=FD
thus; M= (5 kg)3m
from; 1 kg= 10 N
5 kg= 50 N
M= (50 N)3m
M=150Nm

What is a webpage?
Webpage is a document which is written in HTML (hypertext markup language) and is translated by a Web browser. Eg. Opera, Mozilla, internet explorer etc
Web page is what makes up the World Wide Web. Web page can either be static or dynamic.
Static page shows the same content each time when it is viewed. Dynamic page has content that can change each time when it is accessed. NB the browser translates the HTML
Or
A web page or webpage is a document which is written in Hypertext Markup Language
(HTML) that is accessible through the Internet or other network using a browser.
A web page is accessed by entering a URL (universal resource locator) addresses through a web browser.
What is a web browser?
A web browser is software that displays a web page on a monitor or mobile devices. Example of a web browser internet explorer, opera, Mozilla Firefox etc
On a network, a web browser can retrieve a web page from a remote web server.
What is a domain name?
A domain name is a website name. A domain name is the address where Internet users can access a website. A domain name is used for finding and identifying computers on the Internet. Computers use IP addresses, which are a series of number. However, it is difficult for humans to remember strings of numbers. Because of this, domain names were developed and used to identify entities on the Internet rather than using IP addresses.
Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name. Every domain name is unique. No two websites can have the same domain name
Example yahoo.com ,google.com,studentgiri.com
In Google.com, .com is the TOP LEVEL DOMAIN NAME.
What is URL means?
URL stands for Universal/uniform Resource Locator. It is the address of a web page. Each page has its own unique web address (URL). This is how your computer locates the web page that you are trying to find.
An example of a URL is: http://funbrain.com/index.html. In this example URL, funbrain.com is called the domain name. The "index.html" refers to the specific page.
So
Structure of a URL is like this:
http protocol
:// domain / path
It is combination of protocol, domain and path (sometimes port also). Here port
is hidden as default port with http protocol is always 80.
Universal/uniform Resource Locator |
Domain name |
URL is a specific page, http://necta.go.tz/csee_results =URL(specific file in a website) http protocol
:// domain / path http://www.google.com/something_else is a URL |
where as a
domain name is more generic. http://necta.go.tz =website /(show general content) http://www.google.com is a DOMAIN NAME |
Elements of a webpage.
A web page may contain different elements/ different types of data such as
Text/word,
sound,
video,
graphics, and
hyperlinks to other web pages and files.
When was the first web page created?
The first web page was created at CERN by Tim Berners-Lee and put online August 6, 1991
Different between a webpage and a
website.
A Web site is a collection of one or more pages which are linked together by using hyperlinks
Hyperlinks are represented by specific texts or images that enable a user to navigate /move/ transfer from one web page to another.
Whereas
Webpage is a document which is written in HTML (hypertext markup language) and is translated by a Web browser. Eg. Opera,mozilla,internet explorer
A website may have a home page, a contact Us page, a Schedule page, a login page and so on and so forth. All of them together would be the site.
When we type an address in the address bar of some browser like Internet Explorer ,we are referring actually to the website or the address of the website which in technical terms is called URL or Uniform Resource Locator.
Thus, it is just like you ask what the difference between a book and papers is.
¨ This is a website of Necta
¨
www.necta.go.tz
What is a hyperlink?
Hyperlink is an element in an electronic document that links to another place in the same document or to an entirely different document. Typically, you click on the hyperlink to follow the link . Or
A hyperlink is a word, phrase, or image that you can click on to jump to a new document or a new section within the current document. Hyperlinks are found in nearly all Web pages, allowing users to click their way from page to page. Text hyperlinks are often blue and underlined.

Added in Web Development
Though it is impossible under normal circumstances,
A machine can achieve 100% efficiency provided that there is no friction,
But that is impossible as since the machine parts are in contact there will always be friction,
Also a machine becomes fully efficient if Work output is greater than work input, but it's also impossible because energy MUST be used to run the machine.
