Langkah-langkah Menginstal Virtual PC

01.55 |

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 4.5MSXML 6.0 keatas. Pastikan kalian telah memilikinya atau instalasi tidak dapat berjalan.  keatas dan
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. 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
   
   
   

local-area network

A computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN). Most LANs connect workstations and personal computers. Each node (individual computer ) in a LAN has its own CPU with which it executes programs, but it also is able to access data and devices anywhere on the LAN. This means that many users can share expensive devices, such as laser printers, as well as data. Users can also use the LAN to communicate with each other, by sending e-mail or engaging in chat sessions. There are many different types of LANs Ethernets being the most common for PCs. Most Apple Macintosh networks are based on Apple's AppleTalk network system, which is built into Macintosh computers. The following characteristics differentiate one LAN from another: topology : The geometric arrangement of devices on the network. For example,devices can be arranged in a ring or in a straight line. protocols : The rules and encoding specifications for sending data. The protocols also determine whether the network uses a peer-to-peer or client/server architecture. media : Devices can be connected by twisted-pair wire, coaxial cables, or fiber optic cables. Some networks do without connecting media altogether, communicating instead via radio waves. LANs are capable of transmitting data at very fast rates, much faster than data can be transmitted over a telephone line; but the distances are limited, and there is also a limit on the number of computers that can be attached to a single LAN.

BUS NETWORK

bus network Last modified: Monday, August 05, 2002

A network in which all nodes are connected to a single wire (the bus) that has two endpoints. Ethernet 10Base-2 and 10Base-5 networks, for example, are bus networks. Other common network types include star networks and ring networks. For network diagrams, see Network Topology Diagrams in the Quick Reference section of Webopedia.

LAN

Local Area Network (LAN)

Local Area Network (LAN)Local area network (LAN) is a data communication system which allows a number of devices or computers to communicate directly Threaded each other. Inside there are three known types of LAN architectures: Ethernet, Fiber Distributed ringdan token data interface (FDDI).LAN ArchitectureNetwork Architecture consists daripengkabelan, topology, packet format and access methods. Architecture commonly used in cable-based LAN network is electrically, through the development of optical technology is now widely used fiber optic cable as an alternative media and their advantages and disadvantages.The wiring system has been discussed in the media Trasmisi Wired in this section will discuss the architecture topology, access method, and packet formats.Network architecture born during the transition state. ARCNet, Ethernet or Token-Ring is one example of the old architecture that will soon be replaced with other architectures with a higher speed.Network architecture which is now widely used, although considered obsolute, supports transmissions ranging from 2.5 Mbps for ARCNet network, 10 Mbps and 16 Mbps for Ethernet Token-Ring network. This network architecture has been developed for higher performance, the network was increased to ARCNet ARCNet 20MBps Plus and Ethernet upgraded to 100 Mbps Fast Ethernet and 1000 Mbps (1 Gbps) with the name of Gigabit Ethernet.In addition to existing development, also began to implement new architectures such as fiber optics, or Fiber Distributed Data Interface (FDDI) danAsynchronous Transfer Mode (ATM). Latest technology for fiber optic adalahSynchronous Optical Network (SONET).Apart from copper cable network, also known wireless network or wireless. The wireless network uses radio wave transmission systems and microwave (microwave). Fiber optics has the advantage of the same wireless network compared to copper wires that reach a longer distance. Optical fiber is widely used for cross-island and cross country more often called-sea cables, while wireless using satellite communication. The weakness of satellite communications compared to the sea cable is a communication-satellites have a higher average delay time.

IP address

Change your IP Address to England

How to get an English IP address   (by iPrivacyTools)

WHY WOULD YOU WANT TO CHANGE TO AN IP ADDRESS IN ENGLAND?   Well, perhaps:

• You are an English citizen wishing to access English websites as if you're at home.
• You are an Internet entrepreneur wanting to review your marketing campaigns in England.
• You are learning English and desire to surf the Internet as if you are located in England.
• You are an English traveler and your bank only allows online access from within England.
• Etc, etc, etc.

First, a legal note:
We are not lawyers, and we do not have the resources to answer questions about whether any method on this page will allow you access to a particular website. There are many "grey" areas (e.g. Does an English citizen with a physical server located in their own country have the right to access otherwise restricted services? Or does an English soldier have the right to view their online bank account, or watch a sporting event in his or her home country, while stationed overseas?). These issues will vary from website to website, and country to country. The fact is that if a website is absolutely serious about blocking all and every non-local visitor, they'll be able to do so. Given the plethora of websites that restrict geographic access to some degree, it is up to you to get permission, read the terms of use, consult with a legal advisor, or do whatever else it takes to determine whether or not you are acting within a website's acceptable use policy by utilizing any of the information or options listed on this page.

OPTION #1 to change IP address to England: Web Proxies

Web proxies are simply websites that relay your Internet requests. You will typically go to the website that hosts the web proxy, enter the URL that you want to access, and the website will then display the requested page in a frame. If effective, the website visited will only see the IP address of the web proxy, and not your own.
POSITIVE: They're usually free, and their speed is usually tolerable.
NEGATIVE: They are often ad supported, so you'll encounter a lot of popups; They may not be compatible with certain protocols, such as video or SSL; Relay of your personal/private information is usually not secure, so you should not enter any passwords or financial info; They are easily broken (meaning your IP may be exposed via popups, etc) ; Web proxies for England are rather difficult to find.
To give it a try, do a Google search for "England web proxy". As mentioned above, they're a little difficult to find for England.

OPTION #2: Free HTTP Proxy Servers

HTTP Proxies are also a type of relay service, but they are accessed by configuring your web browser rather than by typing a URL into a website. If setup to be "anonymous", the websites you visit will only see the IP address of the HTTP proxy, and not yours.
POSITIVE: They're not as easy to break as web proxies, because even popups that appear in your browser will have to go through the relay; No ads will appear.
NEGATIVE: They are often not compatible with SSL, so they're not safe for logging into membership sites, accessing email, or making purchases; They often run very slowly (perhaps due to overuse); It's difficult to know who is operating the relays and whether they might want to intercept your data; They're difficult to find for England.

OPTION #3 to Get an IP address in England: Paid Proxies

If you need a reliable Internet connection through an IP address in England, you're probably going to end up spending at least a little money. While there are some free options, mentioned above, subscribing to a fee-based service will give you an incredibly more convenient and secure means of accomplishing your objective.
As with the previous options, a paid proxy will also route your web requests through a server in England (that's the only practical way to appear that you're surfing with an English IP address). However, the few advantages mentioned below make the process a lot more logical for most purposes.
POSITIVE: Faster and more reliable than free options; SSL compatible, so you can safely access membership sites, email, shopping sites, and more.
NEGATIVE: They are only compatible with your web browser (but of course that is what most people need to change their IP address for); They cost money.

OPTION #4 for getting an English IP address: VPN Service

VPN, which means "Virtual Private Network", is a secure method of connecting to a remote network, such as logging into an office server from your home. If the VPN is setup to do so, it can also act as a relay for web requests (not unlike a proxy), and be your virtual IP address in England. There are some distinct advantages that a VPN has over a proxy, most notably the ability to relay data for most Internet applications without special configuration.
POSITIVE: Works with most programs that access the Internet (browsers, chat programs, email clients); Can be configured to encrypt your Internet traffic (which makes activities like public WiFi connections more secure).
NEGATIVE: Typically a little higher priced than proxy services.
If you're interested in VPN, we currently feature two services:

1. Standard VPN service on shared IP addresses in the U.K. or U.S. for $10 per month.
2. Deluxe VPN service on a private IP address in the U.K., U.S., Australia, Canada, France, Germany, Netherlands, Spain, or Switzerland for around $15 per month. Please inquire for pricing in other countries.
