The fourth article of my series is an overview of Input/Output devices for the computer. Without input and output, a CPU, RAM and drives cannot get data or display it for use. I/O devices provide the method that a CPU is useful for humans.
This is the second article of the series I am writing about computers. A CPU is the focus of a computer but without Random Access Memory (RAM), it would be harder to use. A CPU has a very small amount of memory to store instructions. If software was limited to that memory, the registers, complex program would not be possible. Other methods can be used to get data into the CPU, but they also bring in limits. The next sections discuss what RAM does and how it affects the computer experience.
This is the starting place for my articles about computers. It seems fitting to start with the Central Processing Unit (CPU), which is the key component of modern computers. The first part of my article will describe how a CPU works. The second part of the article will be an examination of how the design and usage of a CPU affects computers and how they are used.
