LANGKAH - LANGKAH MEMBUAT VIRTUAL PC

Sistem operasi yang didukung dengan baik Microsoft Virtual PC umumnya adalah yang berasal dari keluarga Microsoft sendiri seperti Windows 98, XP, Vista. Untuk linux dukungannya kurang, lebih baik memakai Software virtualization yang lain seperti VMWare (sayangnya tidak gratis).

Kelemahan saat ini adalah tidak didukungnya USB drive oleh virtual PC. Pada VMWare USB Drive telah didukung.

Hari ini Saya akan melakukan demo pada platform windows XP SP2. Perlu diingat, Saya sarankan memory komputer minimal 1 giga dan free spaces minimal 10 giga. Sistem Operasi Guest dari Virtual PC memakan sejumlah besar memory dari sistem operasi host (OS dimana virtual PC berjalan).

Sebelum memulai Saya mengingatkan, yang disebut Guest adalah operating sistem pada virtual PC sedangkah Host adalah operating sistem asli/utama kalian.

Berikut adalah langkah-langkahnya :

1. Download Microsoft Virtual PC 2007 SP1 dari http://www.microsoft.com/windows/downloads/virtualpc/default.mspx
   Note: Installer Microsoft Virtual PC juga memerlukan software pendukung seperti windows intaller 4.5 keatas dan MSXML 6.0 keatas. Pastikan kalian telah memilikinya atau instalasi tidak dapat berjalan.
2. Setelah selesai mendownload, segera install. Langkah-langkah instalasi umumnya gampang (tinggal klik saja tombol Next)
   
   
3. Jalankan Microsoft Virtual PC dari Start –> Program –> Microsoft Virtual PC
   
   
   
   
   
   
   
4. Bila belum memiliki setting satu pun Virtual PC kalian akan mendapatkan Wizard seperti dibawah ini (Klik saja next)
   
   
   
   
   
   
   
   
   
5. Pilihlah create virtual machine
   
   
   
   
   
   
   
   
   
6. Pilihlah sebuah nama untuk guest OS kalian. Nama bebas tapi Saya menuliskan “WinXP Test Platform”
   
   
   
   
   
   
   
7. Karena Saya akan menginstall windows, maka saya memutuskan untuk memilih windows XP dari drop down list.
   
   
   
   
   
   
   
8. Adjust RAM menjadi 512 MB. Defaut RAM yang hanya 128 MB sangat kurang. Note: hati-hati dalam adjust RAM ini karena sejumlah inilah RAM dari host akan tersita oleh Guest. Karena inilah saya sarankan memory host OS minimal 1 giga.
   
   
   
   
   
   
   
   
   
9. Berikutnya kalian akan membuat sebuah Harddisk untuk Guest OS. Bentuk fisik dari HDD ini sebenarnya hanyalah sebuah file. Tentu saja ukuran filenya bisa besar sekali mencapai lebih dari 2 giga bila seluruhnya telah diinstall. Pilihlah “new virtual disk”, default setting yang memberi ukuran hdd virtual sebesar 60 giga byte telah sangat memadai.
   
   
   
   
   
   
   
   
   
   
   
   
10. Wizard selesai, klik saja finish. Berikutnya adalah memasukkan Windows XP CD kedalam CD Rom drive dan start virtual machine.
    
    
    
    
    
    
    
11. Pastikan CD windows XP berada pada cdrom drive, dan start virtual machine. Ada 2 cara menjalankan virtual machine. Pertama dengan mengklik virtual machine file (*.vmc) atau Klik start pada Virtual PC Console.
    Note: beberapa setting pada virtual machine masih grayed out karena Guest OS belum terinstall dan belum memiliki software “Virtual Machine addition”.
    
    
    
    
    
    
    
    
    
    
    
    
12. Lakukan instalasi seperti biasa (bagaimana cara menginstalasi windows XP diluar dari tutorial ini). Coba lakukan googling bila ingin mendapatkan tutorialnya.
    
    
    
    
    
    
    
    
    
    
13. Setelah OS terinstall dan kalian dapat boot kedalam, waktunya menambahkan sebuah Virtual Machine Additions. Klik pada menu Action dan pilih “Install or Update Virtual Machine Additions”. Kalian akan mendapatkan warning, klik saja continue dan lakukan install. Setelah install selesai, restart system.
    Note: Bila kalian merasa cursor mouse terjebak dalam OS Guest (tidak bisa move ke OS Host) tekan saja tombol ALT yang disebelah kanan keyboard (jangan yang kiri!).
    
    
    
    
    
    
    
    
    
    
    
    
14. Selamat kalian sudah membuat sebuah Virtual PC " src="http://s2.wp.com/wp-includes/images/smilies/icon_smile.gif?m=1221156833g" /> . Berikutnya adalah dasar-dasar manipulasi file
    
    
    
    
    
    
    
    
    
15. Untuk mengcopy sebuah file dari host ke guest, klik dan drag sebuah file dari desktop/folder ke dalam virtual pc seperti pada gambar dibawah ini. Hal yang sama juga berlaku bila kalian ingin mengcopy dari guest ke host.
    
    
    
    
    
    
    
    
    
16. Kelemahan dari cara diatas adalah bila kalian ingin mengupdate file pada guest kemudian perubahan ini ingin juga diimplementasikan pada host maka kalian akan sering click and drag. Cara lain yang lebih baik adalah membuat sebuah shared folder. Langkahnya adalah sebagai berikut:
    1. Klik edit -> setting
       
       
       
       
       
       
       
    2. Ke pilihan shared folder dan buat sebuah share folder
       
       
       
       
       
       
       
    3. Kemudian untuk mengakses shared folder, gunakan windows explorer pada guest operating system dan browse ke dari Y (atau drive letter lainnya bergantung dari mapping).
       
       
17. Menu setting juga dapat digunakan untuk mengedit nilai-nilai lain seperti besar memory etc.

Note:

1. USB Drive tidak didukung oleh virtual PC!
2. Ukuran file virtual PC cukup besar, bahkan sudah mencapai 1,4 gb padahal baru windows yang diinstall
   
   
   
   
   

Sekian tutorial saya, Happy Virtualization

Hardware For Internet Access
        To be able to access the Internet, there are several hardware devices (hardware) that are required are:
1. Computer
2. Modem
3. Telephone channel
        1. Computer
Computers are a major component to be mengkases Internet. Specifications used in the computer internet connection is fast or slow performance determines internet access. the higher the specification of a computer, the faster the performance of Internet access, and vice versa.
Minimum specifications of a computer in internet access among others as follows:

        o Processor
is the brain of the computer to run applications in a computer. Minimum Pentium III 500MHz processor.

        o RAM (Random Access Memory)
serves as a temporary storage media. Minimum 64MB RAM

        o Hard Drive
used for magnetic data storage media. At least 10GB hard drive

        o VGA card
is the hardware for menampilakan image on the monitor screen. At least 4MB of VGA cards

        o Monitor
an output device to display the work process of the computer.

        2. Modem
Modem acronym derived from modulator demodulator. Modulator is a part that converts the signal into the information carrier signal (carrier) and ready for delivery, while the Demodulator is the part that separates the information signal (which contains data or messages) of a signal (carrier) that accepted so that the information can be well received. Modem is the combination of both, it means the modem is a two-way communication tool.
In short, the modem is a tool to convert digital signals into analog signals your computer and vice versa. Computers that connect to the internet connected to telephone lines via modem. Based on its function divided menjai three types of modems. Among others:
Modem Dial Up
Dial Up Modem commonly used by the Personal Computer (PC) is directly connected via phone lines. Type of dial up modems have two types, namely:

        1) Internet Modem
Modem is installed in the computer, especially on the available expansion slot in your computer mainboard. Average speed of the internal modem to download is 56 Kbps. The advantages of using an internal modem bellow.

a) More efficient places and more economical price
b) Does not require an adapter so impressed a lot more concise without cables.
While the weakness of the internal modem as follows:
a. This modem does not require the indicator light so it is difficult to monitor modem status
b. This modem does not use the voltage source itself and thus require power from the power supply. This causes the temperature within the CPU box to get hot.
        2) External Modem
External modem is a modem that is located beyond the computer CPU. External modem connected to a computer via USB Ort com or. Installation of this modem by connecting the modem to the power adapter and connect it again then reconnected to the mains. Gain an external modem:
a) Portability is good enough so that it can move around to use on another computer
b) Equipped with indicator lights making it easy to monitor the status of the modem.
The weakness of the external modem.
a) the price is more expensive than internal modems
b) takes place or a separate location to put the modem.
        • Cable Modem
Cable Modem (Cable Modems), is hardware that connect a PC with a TV connection cable. This cable TV network can be used to connect to the Internet at speeds higher than dialup modem or ADSL modem, cable modem speed of maximum 27Mbps downstream (to the user's download speed) and 2.5 Mbps upstream (upload speed of the user). Before you can connect to the internet, then the user is required to perform registration service provider for cable TV and ISP (Internet Service Provider).
        • Modem ADSL (Asymmetric Digital Subscriber Line)
ADSL or Asymmetric Digital Subscriber Line is a form of DSL technology. Characteristic of ADSL is its asymmetric, ie that the data are transferred in a different speed from one side to another. Main idea of ADSL technology to break adalh telephone line signal into two parts for voice and data. This allows users to has to or meneima calls and connect to the Internet simultaneously without interrupting each other.
        3. Phone Line
Phone lines is also an important and hardware required to connect a computer with internet. The use of telephone sauran was also followed by the use of modemdial ups. In addition to phone lines, to make Internet access can also be done by using cable TV. To be able to access the internet using a modem, the cable TV network used is a cable modem.
 
SOFTWARE (Software)
SOFTWARE (Software) That is a collection of data as well as instructions that can be executed by the computer. Generally, software is divided into five types:

        1.Operating System
Is a program created to control and coordinate the activities of a computer system. Operating System generally made for a particular type of computer.
Example:
Microsoft Windows 1995
Microsoft Windows 1998
Microsoft Windows 2000
 Microsoft Windows ME
 Microsoft Windows XP
 Of Microsoft Windows Vista
 Linux Mandrake
 MacOS for Apple Macintos
 SunOS for Sun Computers
 OS / 2
 AIX
 OS/390
 Windows CE for Palmtop

        2. Programming Language
Is the program used to translate instructions written in a programming language into machine language that is understandable by computers.

Programming Language consisting of:
a) Low Level Language Program (Program of low-level languages) example:
 COBOL (Command Business Oriented Language)
 FORTRAN (Formula Translator)

b) High Level Language Program (high level language program) Example:
 BASIC (Beginners All-Purpose Symbolic Instruction Code)
 Fox Pro
 Visual Basic
 Visual FoxPro

        3. Application Program

Program is the result of the Programming Language and is used for the purposes of special perluan
Example: Program on Taxation, accounting, hospitality and others.

        4.Package Program
Is a program created by the software manufacturer for the purposes of a general nature.

The program package consists of:
a. Word Processor (word processor), for example: WAS, WP, Lotus Amipro, ChiWriter, Microsoft Word, Symphony Document.
b. Spread Sheet (processor number), for example: Lotus123, Microsoft Excel, Quatro Pro, Symphony Spread Sheet.
c. Data Base (Data Processing), for example: dBASE IV, Microsoft Access
d. Desktop Publishing (combine text, graphics and tables in one document), for example: Ventura, Page maker.
