Cygwin Overview

• Cygwin offers a UNIX like environment on top of
  MS-Windows.
• You can use UNIX/LINUX utilities programs (gcc,
  vi, emacs grep, ) under MS-Windows
• UNIX programs can be ported to cygwin and run
  under MS-Windows OS.
• assist developers in migrating applications from
  UNIX/LINUX to the Microsoft Windows platform
• Does not require a UNIX administrators level of
  expertise to setup and maintain.

Cygwin Description

• Cygwin consists of
• a library that implements the POSIX system call
  API in terms of Win32 system calls
• a GNU development toolchain (such as gcc and
  gdb) to allow software development
• a large number of application programs
  equivalent to those on the Unix system

5
Cygwin Features

• Command line tools
• Compiler (gcc, g77, g, make)
• Network tools (ssh, scp, rsync)
• Programming tools (splint, indent)
• Version control system (cvs, rcs)
• File tools (diff / patch, head / tail / cut, od)
• Shell scripting (bash, tcsh, zsh)
• Archive (tar, gzip, bzip)
• Man Pages
• Interpreters (expect, Tcl/Tk, perl, python)
• Editors (vi, pico (see pine), emacs)
• Easy copy / paste between cygwin and MS-Windows
  programs (rxvt)
• Scheduled task capability (cron)
• Extension ImageMagick (convert)
• Extension CD Images (mkisofs)

• GUI based tools
• Xemacs
• xv
• Ghostscript
• Extension GrADS

Virtual Machine(VM) - Overview

• Software implementation of machine (computer)
  that executes programs like a real machine
• System VM
• provides a complete system platform ex)
  VMware workstation
• Advantage of system VM
• Multiple OS environments can co-exist on the sma
  emachine in strong isolation from each other
• VM can provide an instruction set architecture
  (ISA) that is somewhat different from that of the
  real machine
• Process virtual machine
• Is designed to run a single program, supports
  single program
• Provide platform independent programming
  environment. ex) JAVA VM.
• JAVA bytecode. write once, run anywhere (WORA)

VMware Workstation

• successful VM software made by VMware, Inc.
• VM software for desktop x86-type PC
• allows users to
• set up multiple x86 and x86-64 virtual computers
• Use several virtual computers simultaneously with
  the hosting OS
• Each virtual machine instance can execute its own
  guest OS (e.g. LINUX, MS-Windows, )
• Allows multiple applications to run in isolation
  within virtual machines on the same physical
  machine
• Easily speacking,
• VMware Workstation allows one physical machine to
  run multiple operating systems
  simultaneously

VMware Characteristics

• Partitioning
• Run multiple operating systems on one physical
  machine
• Isolation
• Isolate faults and security at the
  virtual-machine level
• Dynamically control CPU, memory, disk and network
  resources per virtual machine
• Encapsulation
• Encapsulate the entire state of the virtual
  machine in hardware-independent files
• Save the virtual machine state as a snapshot in
  time
• Re-use or transfer whole virtual machines with a
  simple file copy
