1. Which Microsoft-based technology was developed to link desktop applications to the World Wide Web?
- Active Channel
- Active Desktop
- ActiveX
- None of the above
Show Answer
Answer: ActiveX
ActiveX is a technology developed by Microsoft that enables the connection of desktop applications to the World Wide Web. It allows web content to be downloaded and executed on a user’s computer, essentially providing a framework for embedding interactive elements in web pages. ActiveX controls are used to extend the functionality of web browsers, enabling tasks like multimedia playback, interactive forms, and more. However, ActiveX has raised security concerns due to its potential to download and execute code from the web, making systems vulnerable to malware and exploits.
2. The terms Goodput, Throughput, and Maximum throughput are most closely associated with which aspect of computers?
- Bit Rate
- Response Time
- Command Line Interface
- Random memory
Show Answer
Answer: Bit Rate
These terms are associated with the concept of bit rate, which represents the number of bits processed or conveyed per unit of time. Goodput, often used in the context of network performance, refers to the actual useful data transferred over a network, excluding overhead and retransmissions. Throughput is a broader term, encompassing the total data transfer rate, including both useful data and any additional data needed for network operations. Maximum throughput, on the other hand, represents the highest data transfer rate that a network or channel can support under ideal conditions, without considering practical limitations or network congestion.
3. Which networking technology is used when centralised management is desired or if there is little room for cabling?
- Local Area Networking
- Wide Area Networking
- Passive Optical Local Area Networking
- Optical Area Networking
Show Answer
Answer: Passive Optical Local Area Networking
POLAN is a networking technology used when centralized management is desired or when physical space for cabling is limited. It leverages passive optical network infrastructure, using fiber optics to distribute data and services within a building or campus. POLAN offers several advantages, including the ability to centralize network management, support for high bandwidth, and cost-effectiveness in large-scale deployments.
4. What is the full form of DHCP?
- Dynamic Host Configuration Protocol
- Destined Host Configuration Protocol
- Data Hosting Central Protocol
- Dynamic Housing Central Protocol
Show Answer
Answer: Dynamic Host Configuration Protocol
DHCP is a network protocol used to automatically provide IP addresses and configuration information to devices on a network. It simplifies the process of IP address assignment, ensuring that devices can connect to a network and communicate without manual configuration. DHCP servers dynamically allocate and manage IP addresses for devices, making it a fundamental technology in modern network environments.
5. What is the name given to the computers on a network?
- Point
- Server
- Nodes
- Connection
Show Answer
Answer: Nodes
In networking, computers or devices connected to a network are commonly referred to as nodes. These nodes can be personal computers, servers, printers, routers, or any other device capable of sending and receiving data on a network. The term “nodes” is a generic way of addressing the various entities that make up a network.
6. What is the term for the technique of connecting computers in a network?
- Node
- Topology
- Architecture
- Ring
Show Answer
Answer: Topology
Topology in networking refers to the arrangement of nodes, devices, and connections within a network. It defines how data is transmitted between nodes and how devices are interconnected. Common network topologies include bus, star, ring, and mesh. The choice of topology can impact network performance, scalability, and fault tolerance.
7. Which of the following are the primary ways to enable LAN connections?
- Ethernet
- Wi-Fi
- Both a and b
- None of the Above
Show Answer
Answer: Both a and b
Local Area Network (LAN) connections can be established using various technologies. Ethernet is a wired technology that relies on physical cables for data transmission. It is a common choice for LANs, providing high-speed, reliable connections. Wi-Fi, on the other hand, is a wireless technology that enables devices to connect to a LAN via radio signals. Both Ethernet and Wi-Fi offer distinct advantages, and the choice depends on specific networking requirements.
8. Which technology uses a token-bus scheme for managing line sharing among devices on a LAN?
- Netware
- Interface
- ARCNET
- Ethernet
Show Answer
Answer: ARCNET
ARCNET, short for Attached Resource Computer Network, is a LAN technology that uses a token-bus scheme for managing line sharing among devices on the network. It is an older LAN standard that once had popularity in specific industrial applications but has been largely replaced by more modern networking technologies.
9. What is the connectivity range of a Personal Area Network (PAN)?
- 10 meters
- 7 meters
- 6 meters
- 9 meters
Show Answer
Answer: 10 meters
A PAN is a network with a limited connectivity range of up to 10 meters. It is designed for devices in close proximity to each other, such as personal devices like smartphones, tablets, and laptops. Bluetooth is a common technology used for PAN connections.
10. What is the term for a network that is connected to the Internet but uses encryption to scramble all the data sent through it?
- My network
- Virtual Private Network
- Social Network
- None of the above
Show Answer
Answer: Virtual Private Network
A VPN is a network connected to the Internet that uses encryption to secure the data transmitted over it. It creates a private, secure communication channel over a public network, ensuring the confidentiality and integrity of data. VPNs are commonly used for remote access to corporate networks, securing online transactions, and ensuring privacy when browsing the web.
