Introduction to Computing

 At the core of the lesson

  You will learn how to do the following:

•  Express the value of technology.

•  Define basic computing terms.

Your digital world

                                             

  Think about the last thing that you did online. Perhaps it was to purchase an item from Amazon, play an online game, or chat with a friend. 

 How did you do it? Today, you can use many different types of devices to perform these activities, including smartphones, desktop computers, and game consoles. You also use applications, or apps, and of course, the internet.

Technology in your life 

                                           

 Today, you can use technology to extend your activities beyond physical,geographical, and time limits. You live in a digital world, and technology plays an integral role in your life. 

Building blocks of the digital world 

                                                                          

Applications, computers, and networks are at the heart of the technology that runs the digital world. Devices such as smartphones, tablets, and e-readers are essentially computers. 

Basic computing terminology 

Computer application

                                 

• An application is a computer program. It is a set of instructions that runs on a computer to perform a specific function.
• Programs can be written in many different programming languages, such as Java, Python, and C++.
• The term software is synonymous with computer programs. 

Types of applications  

Many different types of applications exist. They can be differentiated based on what
type of device they run on and how they are accessed.
The following list contains some examples of different types of applications:
                        • Web application – Anything that can be accessed through a web browser, such as Mozilla Firefox (for example, amazon.com)
                        • Mobile application – Amazon Shopping Mobile App and your bank’s mobile
banking app
                        • Desktop application – Word processors, web browsers, games, video editing software, and programming tools
                        • Internet of Things (IoT) application – Applications on a smartwatch or inside a smart refrigerator, and a global positioning system (GPS) navigation application in a car.

Computer network

                                         

• An application that runs on a given computer might interact with other applications
  that run on different computers to access information and complete its function. For
  example, mobile apps often communicate with other applications that run on a web
  server to get data. These different computers can use a computer network to connect and communicate with each other.
• In a wired network, computers use wires, typically Ethernet cables, to connect to a
  router. In a wireless network, computers connect to a router by using the router’s Wi- Fi signal.  

Operating system                                                    

• An OS manages a computer’s hardware and software. You also use it to interact with
  your computer.
• Some applications work only on specific operating systems. 

Key Takeaways 

                                                 

• Applications, computers, and networks run the digital world.

• An application is a computer program. It is a set of instructions that a computer runs to perform a specific task.

• A computer consists of Hardware and Software.

• A computer network is used to perform data transfer from one device to another device.
