Document Summary
There are three broad categories for computing devices: Personal computers - they are general purpose and low performing machines for smaller tasks. These devices are seen as being in between a personal computer and an embedded system. Some might consider these to be totally different systems. These are harder to categorize with devices like smart phones and tablets. Cloud computing systems are in a totally different category compared to personal desktops and handheld computers. Server technology has evolved over the years and are now capable of new applications. For example, new saas servers are used to deliver software on rented hardware for a fraction of the price. Computer architecture the aspects of hardware that are visible to the programmer, such as instructions for the computer like word size and data formats. Computer organization (microarchitecture) - how physical components of the machine interact to implement the architecture. A particular computer architecture could be implemented by several different organizations.
