Study Notes

What is a Computer?

A computer is essentially a machine designed to execute instructions and perform calculations quickly and efficiently. It consists of several components working together to process data into meaningful results. At its most basic level, a computer works by taking input from users through various devices such as keyboards, mice, and touchscreens; it stores this information temporarily in memory or permanently on storage media like hard drives and solid state drives before processing them using the Central Processing Unit (CPU), which performs arithmetic and logical operations based on instructions given in code. These processed outputs can then be displayed on monitors or other output devices.

Hardware Components

The physical parts of a computer, known as hardware, consist of multiple components that enable its functionality. Some essential hardware includes:

  • Central Processing Unit (CPU): This is the core component responsible for executing instructions and performing computations.
  • Memory: Memory, also called RAM (Random Access Memory), holds temporary data during computation.
  • Storage Devices: Storage devices store data when the system isn't actively using it. Examples include hard drives, SSDs, and optical disks.
  • Input Devices: Input devices allow you to interact with your computer. Keywords, mice, scanners, microphones, and cameras are all examples.
  • Output Devices: Output devices display or showcase the result of your computing tasks. They include monitors, speakers, printers, and projectors.
  • Motherboard: A motherboard connects everything else inside the computer together and provides the necessary electrical connections between different hardware components.

Software Components

Software refers to programs written to run on computers. There are many types of software, including:

  • Operating Systems: Operating systems manage the interactions among software applications, user interfaces, and computer resources like CPU and memory. Windows, macOS, Linux, and Chrome OS are some popular choices.
  • Application Software: Application software, sometimes referred to simply as apps, is designed to help people do specific jobs, such as word processing, graphics design, spreadsheets, etc. Most common applications fall under this category.
  • Programming Languages: Programmers create these specialized sets of commands or scripting languages that control how computers behave. Some well-known ones include C++, Java, Python, Ruby, JavaScript, and more.


Computers often work best when connected to each other via networks. While there are numerous ways to do so, the two main networking methods are wired (Ethernet cables) and wireless (WiFi). Once networked, they can share files, print documents, access shared resources, and more.

Programming Languages

As mentioned earlier, programmers use various coding languages to tell computers what to do. Here are just a few widely used languages:

  • C++: A powerful language commonly used across gaming consoles, IoT devices, and enterprise-level servers.
  • JavaScript: Designed specifically for web development, it powers nearly every website you visit.
  • Python: Easy to learn yet highly versatile, Python has found wide application ranging from artificial intelligence to scientific research and even business analytics.
