Hello people, today we are going to look at how to create an email address using your device(phone/computer/tablet) step by step.
hope this skill helps you. Thanks

Today we are going to look at internet,
what is internet ?
->The Internet is a worldwide collection of public networks that are linked to each other for information exchange.

The Internet offers a range of services to its users, such as file transfers between Internet users and electronic mail for sending messages. The World Wide Web (WWW), or the Web, is another service that the Internet provides. WWW includes specially formatted documents that are interlinked and stored on servers around the world.

You can use the Internet and its services to send messages to other Internet users, search and apply for jobs, watch movies, and buy and sell products.

Many organizations use a special type of network to communicate and share information within the organization. Such a network is called an intranet.
An intranet is similar to the WWW but is accessible only to authorized users of the organization. An intranet is much smaller than the Internet and can provide services such as document distribution, software distribution, access to databases, and training

In contrast with hardware, today let us discuss about Software.
Software is a collection of instructions and data that tell a computer how to work.
Based on the goal, computer software can be divided into:

Application software
which is software that uses the computer system to perform special functions or provide entertainment functions beyond the basic operation of the computer itself. There are many different types of application software, because the range of tasks that can be performed with a modern computer is so large .
Examples of application software: Microsoft office, internet browsers, music players and etc

System software
which is software for managing computer hardware behavior, as to provide basic functionalities that are required by users, or for other software to run properly, if at all. System software is also designed for providing a platform for running application software and it includes the following:
Operating systems
which are essential collections of software that manage resources and provide common services for other software that runs "on top" of them. Supervisory programs, boot loaders, shells and window systems are core parts of operating systems. In practice, an operating system comes bundled with additional software (including application software) so that a user can potentially do some work with a computer that only has one operating system.

Device drivers:
which operate or control a particular type of device that is attached to a computer. Each device needs at least one corresponding device driver; because a computer typically has at minimum at least one input device and at least one output device, a computer typically needs more than one device driver.

Utilities:
which are computer programs designed to assist users in the maintenance and care of their computers.

Malicious software or malware
which is software that is developed to harm and disrupt computers. As such, malware is undesirable. Malware is closely associated with computer-related crimes, though some malicious programs may have been designed as practical jokes.

Overview of a keyboard
The keyboard is an input device that goes into your computer which allows you enter information such letters from the alphabets, numerical data, symbols, and commands. There are many keyboards, although not all have the same layout style. The most common kind is referred to as a QWERT keyboard, which is named after the keys on the top rows of letters. The
keyboard is divided into several groups

Function keys: The functions keys, labeled from F1 to F12, are used to perform specific
tasks based on the operating system and software used. For an example, in many programs, the key F1 is commonly used as the Help file. In some cases, it can control the monitor brightness or the sound volume. The functionality of these keys differentiates from program to program and operating system to operating system

based on the
function.

Logging Off
Logging off will exit you from the current user that you are using. Any
open programs will remain open and once logged back in will open up,
unless the computer is shut down. Any other users may have their
information open as well.

Restarting
The Restart option is usually used when something is not
corresponding. The Restart option will shut down the computer and
automatically begin to turn on the computer again. Remember that any
unsaved information will be lost if it is not saved if the computer is
restarted.

Shutting Down
Shutting down the computer will completely turn off the whole system.
Any unsaved information will be lost, so remember to save before
shutting down the computer.

To start a computer, you press the power
button. This may cause a small light to
turn on and then the monitor to turn on.
The computer will check all of its
components and if everything is running
smoothly, it will display the welcome
screen, and then to the user screen. Here
you may login into your personal user, or
as a guest. All new computers now have an energy-
saving mode called Sleep that allows the
computer to temporarily shut down all
nonessentials. Usually, there is a light
flashing to indicate that it is asleep. This
is a huge energy saver, using as much
electricity as a Night light and taking
seconds to start up. The computer may
seem to be shut down, except all of your
work will still open and will not be lost. It
takes seconds to turn back on and
continue to work on any pages that were
open, sleep is a very useful tool on a
computer. There are other options; such
as Log off, Restart, and Shut down.
Before doing any of those options, make
sure to save all unsaved items because
they can become lost.

Do not press the power button to shut
down the computer unless the whole
computer has stopped responding and
you can no longer restart it.

The lesson to day is well understand what is a computer is and what are different parts of the computer.
Description
Computing has become a very integral part of everyday life in the twenty-first century.
From music and photos to banking and communicating, computers have changed the
way we work and live. This course introduces you to the fundamentals of computing,
explains the components of a computer, explores operating system basics, and shows
you how to use a mouse and a keyboard. Also explains how computers can be used in
different aspects of life.

Benefits
Computers are used in every field. They help organizations and individuals to conduct
business transactions efficiently and quickly. Today, one of the basic skills necessary to
succeed at a workplace is to know how to use the computer. To be able to get better
jobs, you need to know how to use a computer.

Introduction to computers
A computer is an electronic device that you can use to store and process information.
A computer can be used to help you perform various tasks, such as:

• Send e-mail
• Make Presentations
• Maintain Records
• Write Text
• Organize Files
• And more

The role of computers

Role of computers
Computers impact our lives every day.
Consider a trip to the store and how
many different computers are involved.
Computers are inside your car, manage
the traffic lights, control the
temperature in the store's freezers, and
calculate the cost of your groceries.
Let’s look more at how computers play
a regular role in your life.

Computers contain many parts
including keyboards, monitors,
processing units, memory, and more.
In this lesson we will look at all the
parts of a computer. We will organize
these parts by categories including
input, output, microchips, storage, and
ports.
