Study Notes
Evolution of Computers
- More computers entered commercial markets, moving beyond government and university labs.
- Mainframe computers emerged, characterized by metal frameworks and improved operational capabilities.
- Second-generation computers were cheaper, faster, easier to program, and more reliable but had a short lifespan.
Introduction of Silicon Chips
- The silicon chip was developed in the 1950s and utilized in computers by 1964, marking the advent of the third generation.
- Integrated circuits (ICs) replaced bulkier transistors and magnetic core memories, leading to smaller and faster computers.
- ICs made mass production feasible, reducing computer manufacturing costs and allowing smaller organizations to buy computers.
Moore's Law
- Transistor count on chips has increased exponentially since 1965, doubling approximately every 18-24 months, as noted by Gordon Moore.
- This trend demonstrates significant performance improvements in computers over relatively short periods.
- Even after prediction of a slow down in the 2000s, miniaturization trends have continued.
Comparing Improvements
- Exponential growth in technology surpasses linear improvements, leading to dramatic increases in transistor counts in computers over time.
- Understanding the difference between linear vs. exponential increase is crucial for grasping the rapid advancements in computing power.
Software Development
- Early computers operated on machine language, utilizing a long list of binary codes (1s and 0s).
- Programming advancements introduced language translators: assemblers for assembly language and compilers for high-level languages like FORTRAN.
- FORTRAN was designed for scientific computations, simplifying mathematical representations for programmers.
Operating Systems Emergence
- Early computing lacked operating systems as computers handled one program at a time, requiring all code for I/O operations to be part of the program.
- As computer use expanded, the need for sophisticated management of resources led to the development of operating systems by the mid-1960s.
- Operating systems enabled program scheduling, execution, multitasking, user interface management, and security between different users.
Structured Programming Revolution
- Programming paradigms evolved throughout the 1960s, leading to the introduction of structured programming in the 1970s to improve code organization and readability by minimizing GOTOs.
