Study Notes
Architecture Types
- Client-Server Architecture:
- Server program runs on the server
- Client software is installed on the client
- Server processes background service logic and request data
- Improves communication speed and efficiency between the two ends
- Browser-Server (B/S) Architecture:
- Users only need to install a browser
- Application logic is centralized on the server and middleware
- Improves data processing performance
Server Development History
- Mainframe phase:
- Emerged in the 1940s and 1950s
- Vacuum tube computers developed into large-scale integrated circuit computers
- Midrange computer phase:
- Emerged in the 1960s and 1970s
- Mainframes scaled down for small- and medium-sized enterprises
- Microcomputer phase:
- Emerged in the 1970s and 1980s
- Mainframes scaled down for the second time
- Apple II launched in 1977, IBM-PC launched in 1981
- x86 server era:
- Emerged in 1978 with Intel's 8086 microprocessor
- Pentium series launched in 1993, Pentium Pro launched in 1995
- X86 architecture processor performance improved, leading to cloud computing era
Computing Eras
- Computing 1.0:
- Dedicated computing, mainframe/midrange computer era
- Computing 2.0:
- General-purpose computing, data center, x86 architecture
- Computing 3.0:
- Intelligent computing, full-stack, all-scenario
Server Classification - Hardware Form
- Midrange computer
- Tower server:
- Can use a chassis similar to an ordinary vertical computer or a large-capacity chassis
- Rack server:
- Installed in a standard 19-inch cabinet
- Specifications include 1 U, 2 U, and 4 U
- Multiple servers can be placed in a cabinet for higher processing capability
Understand the basics of client-server architecture, where the server provides background service logic and data, and the client handles user interaction and GUI.
