A.
VLAN

B.
Open network architecture

C.
Intranet

D.
VAN

Explanation:
A: Virtual LANs (VLANs) enable the logical separation and grouping of computers based on resource requirements, security, or business needs in spite of the standard
physical location of the systems. This technology allows Angela to logically place all computers within the same department on the same VLAN network so that all users can
receive the same broadcast messages and can access the same types of resources, regardless of their physical location. This means that computers can be grouped together
even if they are not located on the same network.
B is incorrect because open network describes technologies that can make up a network. It is one that no vendor owns, that is not proprietary, and that can easily integrate
various technologies and vendor implementations of those technologies. The OSI model provides a framework for developing products that will work within an open network
architecture. Vendors use the OSI model as a blueprint and develop their own protocols and interfaces to produce functionality that is different from that of other vendors.
However, because these vendors use the OSI model as their starting place, integration of other vendor products is an easier task, and the interoperability issues are less
burdensome than if the vendors had developed their own networking framework from scratch.
C is incorrect because an intranet is a private network that a company uses when it wants to use the Internet and Web-based technologies for internal networks. The company
has Web servers and client machines using Web browsers, and it uses the TCP/IP protocol suite. The Web pages are written in HTML or XML, and are accessed via HTTP.
D is incorrect because a value-added network (VAN) is an electronic data interchange (EDI) infrastructure developed and maintained by a service bureau. Here’s an example
of how a VAN works: A retail store such as Target tracks its inventory by having employees scan bar codes on individual items. When the inventory of an itemsuch as garden
hosesbecomes low, an employee sends a request for more garden hoses. The request goes to a mailbox at a VAN that Target pays to use, and the request is then pushed out
to the garden hose supplier. Because Target deals with thousands of suppliers, using a VAN simplifies the ordering process. There is no need to manually track down the right
supplier and submit a purchase order.
