  11. 11. Computer Hardware and Software Computer Architecture and Computer Organization Refers to those characteristics or attributes seen by a programmer or user. Examples of these characteristics include:  The instruction set (Add, Subtract, multiply etc).  The number of bits used to represent various data types.  Input/output mechanism  Methods of addressing the main computer memory. Refers to the operational units (such as the Arithmetic and Logic Unit (ALU) and Control Unit (CU) and their interconnections that realize the architectural specification .These include:  Control signals needed for executing arithmetic operations  Memory technology used  Connection to the different peripherals like Printers, display units and so on.
  12. 12. Computers Computer Hardware and Software Types of Computer systems Personal Computers Laptops Handheld Computer Servers and Mainframes Server Farm Supercomputers
  13. 13. Computer Hardware and Software Types of Computer systems Network – Centered Computation LAN WAN Intranet Internet Embedded Computers
  14. 14. Computer Hardware and Software Types of Computer systems Future of Computer systems Autonomic Computing is inspired by the human nervous system and aims at realizing computing systems and applications capable of managing themselves with minimum human intervention. Quantum Computing makes use of concepts based on quantum physics to design computers that can solve problems much more efficiently than current computers. BioComputers use biologically derived materials (e.g. DNA and Proteins) to perform computations. It makes use of Nano-biotechnology to build the chemical components necessary to build such computers
  15. 15. Computer Hardware and Software Types of System Software Operating Systems Language Compilers and Interpreters Windows Linux Java Scripts C & C++ HTML & XML DBMS System Support

  21. 21. Computer Peripherals and HCI Human Computer Interaction  Computer Interaction problems Many computer peripheral equipment that are used by humans do not usually take into consideration the effect on the human sensing organs. Keyboards, mice, visual display units, and virtual reality equipment do not study the effect of using these peripherals and the strain they may cause on humans. Some of these effects will be briefly presented  Focusing problems  Double vision  Headache  Carpal Mechanism Syndrome
