Unified Network Orientation
A
Correct answer
Explanation
Universal Network Objects (UNO) is the component model for OpenOffice.org and LibreOffice, allowing for interoperability between different programming languages and objects across a network. The other options are plausible-sounding but incorrect fabrications.

IEEE 802.11
C,E,F
Correct answer
Explanation
Bluetooth, GSM, and IEEE 802.11 (WiFi) are all wireless communication standards. TokenRing is wired networking, ATM is a cell-switching protocol, and WAP is a protocol for mobile web access (not a wireless tech itself).
A
Correct answer
Explanation
ATM indeed stands for Asynchronous Transfer Mode, which is a telecommunications technology used for transferring digital information. It uses asynchronous time-division multiplexing and was commonly used in telecommunications networks and computer networks. The statement is correct.
-
A new type of cabling system for Wide Area Networks
-
A second local area network that can connect with another online LAN to share access
-
A new standard for Internet browsers
-
An association to develop advanced Internet technology
D
Correct answer
Explanation
Internet2 is a not-for-profit consortium (founded in 1996) that develops and deploys advanced network technologies for education and research. It's not a new cabling system, browser standard, or local area network - it's an association of universities, government, and industry working together on advanced Internet applications and infrastructure.

none of the above
B
Correct answer
Explanation
ARPANET (Advanced Research Projects Agency Network), funded by the US Department of Defense, was the first wide-area packet-switching network. Established in 1969, it pioneered TCP/IP protocols and evolved into the modern Internet. UCLA was one of the first nodes (not the network itself), and DARPA was the funding agency.

Network station
B
Correct answer
Explanation
The network server is the most powerful and central computer in a typical network configuration. Servers manage network resources, handle authentication, store shared data, run applications for clients, and coordinate all network operations. Clients (workstations, desktops) are typically less powerful as they rely on the server for resources and services. The term 'Network station' is not standard terminology.

Data
A
Correct answer
Explanation
Connectivity refers to the ability to link and communicate between computer systems. The Internet is the global network that connects millions of devices, enabling communication and data exchange. Floppy disks and power cards are hardware components, while data is the content being transmitted.

-
Network station
B
Correct answer
Explanation
The network server is the most powerful and important computer in a typical network because it manages resources, provides services to clients, and controls network operations. Clients request services, while servers provide them. The server has more processing power, storage, and specialized network software.

Data
A
Correct answer
Explanation
The Internet is the correct example of connectivity as it connects millions of computers and devices worldwide, enabling communication and data exchange. A floppy disk is storage media, a power card is a hardware component, and data is the content being transmitted - none represent connectivity itself.
C
Correct answer
Explanation
WiFi (Wireless Fidelity) is the common term for wireless computer networks that use radio waves instead of physical cables. LAN and WAN refer to network scope (local/wide area) but don't specify wireless technology. EPABX is a telephone exchange system, not a computer network type.

It all depends on your needs
D
Correct answer
Explanation
No industrial network is universally the best - each has strengths suited to different applications. Profibus offers robust communication, DeviceNet provides efficient manufacturing integration, and Fieldbus has specific advantages. The choice depends on speed, noise immunity, cost, and compatibility requirements.
