Study Notes
The Computer Revolution
- Computers have led to a third revolution for civilization, alongside the agricultural and industrial revolutions.
- This "information revolution" has profoundly changed everyday lives and the way new knowledge is acquired.
- Computational scientists have joined theoretical and experimental ones, exploring new frontiers in fields like astronomy, biology, chemistry, and physics.
- The affordability and power of computers constantly increase, opening up new application possibilities previously deemed impractical.
Computer Applications
- Computers in Automobiles: Microprocessor advancements led to their inclusion in cars, improving pollution control, fuel efficiency, and safety through features like engine controls, automated driving, and airbags.
- Cell Phones: Computer system advancements have enabled widespread use of cell phones, facilitating communication globally.
- Human Genome Project: The project was made possible by the reduced cost of computer equipment for mapping and analyzing human DNA.
Servers and Supercomputers
- Servers: Computers for running programs for multiple users, often simultaneously, accessed via a network. They are often tailored for specific needs, ranging from simple file storage to complex web serving.
- Supercomputers: High-performance, expensive computers, often used for high-end scientific and engineering calculations. They typically consist of hundreds of thousands of processors and terabytes of memory.
- Supercomputers vs. Servers: Supercomputers constitute a small fraction of the overall computer market in terms of revenue.
Factors Affecting Computer Performance:
- Programming Language, Compiler, and Architecture: Determines the number of computer instructions for each source-level statement.
- Processor and Memory System: Determines the speed at which instructions are executed.
- I/O System (Hardware and Operating System): Determines the speed of Input/Output operations.
Seven Great Ideas in Computer Architecture
- Computer architects have developed seven key ideas over the past 60 years, shaping the evolution of computing.
- Instruction Set Architecture: Defines the interface between hardware and low-level software. It encompasses instructions, registers, memory access, I/O, etc., providing a blueprint for creating machine language programs.
- Application Binary Interface (ABI): Combines the instruction set architecture and operating system interface for application programmers. Essentially, it standardizes how software interacts with hardware across different computers, facilitating binary portability.
- The BIG Picture: Both hardware and software are structured in hierarchical layers using abstraction. The instruction set architecture forms a crucial interface between these layers, allowing for diverse implementations while running identical software.
The Importance of Data Storage
- Computers store data in memory, which is volatile.
- Losing power to the computer results in data loss.
Networking Revolution
- Local Area Network (LAN): Carries data within a restricted geographical area, typically within a single building.
- Wide Area Network (WAN): Connects computers over long distances, often across continents.
- Impact of Networking:
- Enabled the rise of the Internet and web.
- Made data transfer more efficient and accessible.
- Improved communication and collaboration.
- Increased the capacity and ubiquity of networks.
- Led to the rise of wireless technology, further shaping the "PostPC Era."
