, Computers are used in three different classes of applications:
1. Personal Computers (PCs): a computer designed for use by an individual, usually incorporating a
graphics display, a keyboard, and a mouse.
2. Servers: a computer used for running larger programs for multiple users.
3. Embedded computers: a computer inside another device used for running one predetermined
application or collection of software
Hardware or software component How this component affects performance
Algorithm Determines both the number of source-level statements
and the number of input/output operations executed
Programming language, compiler, and Determines the number of computer instructions for each
architecture source-level statement
Processor and memory system Determines how fast instructions can be executed
Input/output system (hardware and Determines how fast input/output operations may be
operating system executed
1. Design for Moore’s law: Integrated circuit resources double every 18-24 months. Knowledge for
design for computer technologies changes rapidly.
2. Use abstraction to simplify design: Abstraction is used as a major productivity technique to
shorten the design time.
3. Make the common case fast: Enhance performance better than optimizing the rare case.
4. Performance via parallelism: By performing operations in parallel you get more performance.
5. Performance via pipelining: A particular pattern of parallelism.
6. Performance via prediction: Guess and start working rather than wait until you know for sure.
7. Hierarchy of memories: Fastest, smallest and most expensive memory at the top of the hierarchy
to use the capacity limits of the memory efficiently.
8. Dependability via redundancy: By including redundant components that can take over when a
failure occurs and to help detect failures, the system is dependable.
Systems software = Software that provides services that are useful,
including:
- Operating system (f.a. Windows)
- Compiler: translates high-level language statements into
assembly language statements.
- Loaders
- Assemblers: programs that translate a symbolic version of
instructions into the binary version.
Computers follow instructions in binary code.
