Hi Jim, I'm glad you're interested in learning more about computer hardware. Computer hardware refers to the physical components of a computer system, such as the processor, memory, storage devices, and input/output devices. These components work together to enable the computer to carry out various tasks. When it comes to selecting a computer, there are a few key considerations to keep in mind. The processor, or central processing unit (CPU), is often referred to as the "brain" of the computer. It determines the computer's processing speed and capabilities. The amount of memory, or RAM, also plays a crucial role in determining how quickly the computer can access and process data. In addition to the processor and memory, storage devices are essential for storing data and programs. There are different types of storage devices available, such as hard disk drives (HDDs) and solid-state drives (SSDs), each with its own advantages and disadvantages. Input/output devices, such as keyboards, mice, and monitors, allow users to interact with the computer and input and output data. It's important to consider the type and number of input/output devices you'll need based on your intended use of the computer. As you consider purchasing a computer, it's important to think about the specific requirements and tasks you'll be using it for. For example, if you plan to use the computer for gaming or other resource-intensive tasks, you'll want a computer with a high-performance processor and plenty of memory. I hope this brief introduction to computer hardware has been helpful. If you have any further questions or need more information, feel free to ask. I'm here to help you make an informed decision when selecting a computer that meets your needs.
