MSIS Appendix A Architectural Viewpoints Model:  Logical  Development  Process  Physical Hardware Basics  CPU the brains  RAM the integrated circuits ; works with CPU  Input Device: mouse, keyboard, scanner  Output Device: monitor, printer, headphones  Storage Device: DVD, hard drive  Communication Device  Connecting Device Software basics  Operating system  Utility software  Application software  Word processing  Spreadsheet software MHz or Megahertz are the millions of CPU cycles per second GHz or Gigahertz are the billions of CPU cycles per second CISC: hardware that is multi clock loads and stores instructions high cycles per second count RISC software single clock with reduced instruction low cycles per second RAM is non-volatile so open to losing everything ROM is volatile and not easily lost memory Magnetic Mediums  Magnet tapes Optical Medium: like CDs and such MSIS Appendix B Networks and telecommunications  Metcalfe’s law: value of a network is Nx(N-1), network with 100,000 members as a million dollar value. Revised also to Nxlog(N) to increase a value to 2.1 million.  Three types of networks: LAN (local area network), MAN (metropolitan area network), WAN (wide area network)  Media strengths: fiber-optic, coaxial, then twisted pair  TCP is protocol allowing integrated network telecom. MSIS Chapter 1 How do we measure data?  BIT 0 or 1  Byte 8bits  Kilobyte 1024 bytes-^10 bytes  Megabyte 1024^2 bytes  Gigabyte 1024^3 bytes  Terabyte 1024^4 bytes  Petabyte 1024^5 bytes  Exabyte1024^6 bytes  Zetabyte 1024^7 bytes  Yottabyte 1024^8 bytes First-Mover Advantage normally never wins or stays.
