Essential Tech Knowledge

Hello all,

My name is Marco Garcia and throughout this course I will provide essential knowledge about computers you should know in order to navigate through a computer easily and utilize common functions without help.

Getting Started

Start-up

Power On:

To get started you must locate the power button which can vary depending on the computer you are using. Usually, the power button will look like the image above, the only thing that will change is the location of the power button depending on the computer you have.

Start-Up Page:

When you first get your computer you will get sent straight to the homepage and upon turning it on your device will ask you a series of questions for security and customizing purposes. You will have the ability to set up a pin or password everytime you turn your piece of tech on for your safety.  

Home Page:

The homepage is where the screen defaults to once you turn your computer on and get past your sign-in page. There will be icons of applications around the screen and you will be able to click and drag the icons and place them wherever you please. You are able to add and delete applications from the homepage or otherwise known as the "Desktop". 

You can delete and download new applications to your desktop

  • Desktop=Homepage

Summary

To Sum It All Up:

In order to use your computer, it must first be turned on. Secondly, you must bypass the security whether it be a pin or password that you created of course. If you have not set up a pin or password for your device then you will just have to turn the computer on and click to end up at the homepage. To set up a password you must go to the security settings on your computer. Lastly, it is important to know the differences between the common input and output devices because with these you are able to communicate with your computer in essence. 

Files and Applications

What the Files

Files

file is an object on a computer that stores data, information, settings, or commands used with a computer program. In a graphical user interface (GUI) such as Microsoft Windows, files display as icons that relate to the program that opens the file. For example, the picture is an icon associated with Adobe Acrobat PDF files.

Folders

folder also called a directory, is a special type of file on your computer's file system which contains other files and folders.

The image above displays how the icon for a folder will typically look like on a computer.

Why Are They Important?

Anything you save into your hard drive becomes a file whether it be in the form of an image, audio, video, document, etc. Thus, it is critical that you learn what they are and how you to create and manage files. Folders are like the directories of files therefore, it is also important for you to know how to create and place files into these folders. 

Which icon best represents a folder?

How to manage your files

Apps & More

Application

An app is a type of software that allows you to perform specific tasks. Applications for desktop or laptop computers are sometimes called desktop applications

Apps are essential because without them your computer is useless. Hardware alone cant provide any functions because it doesn't have the software to tell the hardware what to do. There are several millions of apps you can download and they're all up to your preference. However, all apps vary in size when it comes to the data they possess. Hence, the more data they have the more space they take up on your computer, and the memory you have on your computer is limited.

What are applications essentially?

  • Software
  • Hardware
  • Nothing
  • Files
  • Folder

The Internet

What is the internet?

Internet

How to get internet?

Even if you have web browser application such as Google Chrome downloaded onto your computer, there is no way you could have downloaded it without the use of the internet unless your computer had the application pre-downloaded. To utilize the internet you must have a secure connection either wired or wireless.  

Wifi

A facility allowing computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area.

Ethernet

a system for connecting a number of computer systems to form a local area network, with protocols to control the passing of information and to avoid simultaneous transmission by two or more systems.

Which one is better for the internet? 

Both choices were fine if you're within the appropriate range. In short, Ethernet refers to your “internet cable” whereas WiFi is a wireless connection. Wifi is convenient but slower in speeds. Ethernet involves a physical connection but offers potentially faster transfer speeds.

Internet Providers

Who gives me internet?

The image on the right contains different companies that can give you access to the internet, this usually comes with a price of a monthly subscription that can range depending on the speeds you request. 

Name the following web browsers

  • google chrome

Shortcut keys are commonly accessed by using the Alt key (on IBM compatible computers), Command key (on Apple computers), Ctrl key, or Shift key in conjunction with another key. Although the combination of these keys isn't necessary it is really convenient especially when you're in a rush or you don't have a mouse. Also, performing these tricks in front of friends, family or coworkers might impress them if they didn't already know of them. 

These tricks are usually performed by hardcore computer users so knowing them now will definitely put you ahead of other novice computer users.
