Physical integration is mainly a matter of technical or practical import. It may be necessary to make local copies of some data sources in order to ensure reliability or to reduce access times. For example, in the WWW (World Wide Web), Internet service providers often use local caches of popular web sites to improve access time. Because of the way certain servers operate, it may be necessary to have local copies of all data.

Thanks to the Web there is more information from more sources available than ever before. There is also a greater diversity of voices, since any person or group with a PC and Internet service can put up a web site—in some cases a site that looks as polished and professional as that of an established group. One benefit is that dissenting views can be found in abundance.

Network address translation (Egevang and Francis, 1994) is frequently used by private companies and internet service providers to mask the internal structure of their environment and to lessen address space requirements. As such, different machines may be seen as a single one by our application. When NAT is in place, the name resolved through DNS is the name of the NAT device and does not reflect the exact name of the target or source of the event. As a result, our application in this configuration identifies a domain but not the exact target or source. 

If your computer at work is on a local area network (LAN), you may already have access to an external connection. Almost all universities have permanent connections between their internal systems and the Internet. If you don t have access to an institutional connection, you have to obtain an access from an Internet service provider (ISP). For a full Internet connection, you must have software to make your computer use the Internet protocol, TCP/IP, and if your connection is through a modem this software will probably use PPP (point to point protocol).

Some pharmaceutical mamrfacturers are implementing extranet web-enabled applications established with suppliers and business partners. Extranet includes Virtual Private Networking (VPN) and offer cheaper Web solutions. Remote node access is achieved using a client with a browser connected to a corporate Web address or Universal Resource Locator (URL). The challenge is ensuring security across the Internet link. A secure session or tunnel is established between the VPN server and the end user workstation. Internet Service Providers (ISPs) and telecommunications carriers are endeavoring to provide a managed extranet/VPN service to corporate subscribers. A major benefit of Web-enabled applications is the ability to recover from disaster scenarios. Business Continuity Plans can actively make use of such applications.

Pulse pressure is another important consideration for you and your physician. Pulse pressure is essentially the difference between the systolic and diastolic pressure readings. Dr. John Cockcroft, an international authority on blood pressure and hypertension at the University of Wales College of Medicine in the United Kingdom, provided a dramatic example of this in an interview featured on Medscape Cardiology, an Internet service for cardiologists and others specializing in heart health. He explained that if you look at the risk of a cardiovascular event such as a heart attack or a stroke in people with a rise of about 20 mm Hg in systolic blood pressure, the risk is not as great as that from a 20 mm Hg rise in pulse pressure. Dr. Cockcroft said that pulse pressure is often a far better predictor of risk than either systolic or diastolic blood pressure alone. 

Before we can discuss connecting Windows to the Internet, we need to discuss the Internet itself. There are some common terms and concepts every technician must understand about the Internet. First of all, the Internet is really just a bunch of private networks connected together using public telephone lines. These private networks are the access points to the Internet and are run by companies called Internet Service Providers (ISPs). They will sell you a connection to the Internet for a monthly service charge (kind of like your cable bill or phone bill). Your computer talks to the ISP using public phone lines, or even using new technologies such as cable or wireless.
