Mainfram
midrange
PC
Workstation
Super computer
Hardware requirement of ecommerce:
- 24/7 support
- online
- periodical backup
- critical

OS: DOS, UNIX MAC, Windows
Languge Fortran, cobol, IMBM360,
- Programing languuage
- Machine language
- Assembler language : Like "C"
- High level language; source code, this require compilation
Application: custom designed softwares some eg
- control programs: they control the user end softwares
- service programs: used at the customer level (data entry stuff)
- packaged programe: custome made, portable
