  4. Why Java? • Covers all characteristics of high-level languages • Platform independent • Easy to implement web development • Widely used for mobile development • Has been adopted in many distributed environments (Hadoop) • Graph user interface (GUI) design

  5. Introduction to Computer Systems • Hardware components

  6. Megabytes, Gigabytes, Terabytes • 1 Bit = 1 binary digit • 8 Bits = 1 Byte • 1000 Bytes = 1 Kilobyte (Kb) • 1000 Kb = 1 Megabyte (Mb) • 1000 Mb = 1 Gigabyte (Gb) • 1000 Gb = 1 Terabyte (Tb)

  7. CPU and Buses

  8. CPU Two-level Caching System • The first level is on-chip cache (8,192 bytes). • The next level is between on-chip cache and main memory (from 32,768 to 1 megabyte).

  9. The Fetch and Execute Cycle

  10. How to Execute Programs • Translate into languages understood by machines • Compiler • only translates once • Most high-level languages: C, C++, etc. • Interpreter: translates every time you run programs • Most scripting languages: python, perl, etc.
