Assorted computer components like power supplies, cooling fans, disk drives, primary memory, secondary memory, expansion cards, and much more are plugged into the motherboard. Microcomputer Configurations Arizona State University W. P. Carey School of Business Computer Applications & Information Technology It has become common practice to refer to a microcomputer as a box . The box itself is called a case , or chassis which encloses the main components of the computer. Black & White Business Computing 2010 Chapter 2 System Unit: Inside the Box Computer Information Systems 105 System Unit: Inside the Box Microcomputer Configurations (cont.) On the inside of a microcomputer, the core component is the system board commonly referred to as the motherboard. A motherboard is the primary circuit board, which is a complex array of electronics that connects and helps different components of the computer communicate with one another. A circuit board , Arizona State University W. P. Carey School of Business Computer Applications & Information Technology sometimes called a printed circuit board (PCB), is a logical and economical way to replace what would be loose wiring by applying copper wires directly to a sheet of non conductive plastic. A microprocessor , sometimes called a microprocessor chip is plugged directly into a slot on the motherboard and serves as the brains for the microcomputer. Contained within the microprocessor is the central processing unit (CPU) . Black & White Business Computing 2010 Chapter 2 System Unit: Inside the Box Computer Information Systems 105 System Unit: Inside the Box Microcomputer Configurations (cont.) A microcomputer’s speed is measured by clock rate which is the cycles per second that a computer can perform its most basic tasks, measured in gigahertz . Microprocessor manufacturers are constantly trying to improve Arizona State University W. P. Carey School of Business Computer Applications & Information Technology processing speed, and one novel way is through the development of multicore chips, which are simply many chips encased on one chip package working together. RISC (Reduced Instruction Set Computer) architecture chips are designed for efficiency, and were the first 64 bit processors.

Bus lines are the pathways (or roads in our analogy) that transfer data and power between components inside of a computer, and sometimes between computers. Bus lines are controlled by software that enables them to connect peripheral devices like computer cards and printers. Bus lines are measured in bus width .

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
