4. Internet is which type of Network ?
   1. LAN
   2. WAN
   3. MAN
   4. PAN
   Show Answer

   Answer : B
   Explain: The Internet is the example of a WAN (Wide Area Network), connecting all computers together around the world. It covers largest distance.
5. Internet is which type of topology ?
   1. Star Topology
   2. Bus Topology
   3. Ring Topology
   4. Mesh Topology
   Show Answer

   Answer : D
   Explain: A mesh topology is a type of computer network in which each node (computer or other device) is connected to every other node in the network. This type of network is often used in large organisations.
6. URL stands for ?
   1. Uniform Resource Locator
   2. Uniform Resource Link
   3. Uniform Research Link
   4. Undefined Resource Link
   Show Answer

   Answer : A
   Explain: A URL is nothing more than the address of a given unique resource on the Web.
7. What is the full form of HTTP ?
   1. Higher Text Protocol
   2. Hyper Text Tansfer Protocol
   3. Hyper Text Translate Protocol
   4. Hyper Text Transform Protocol
   Show Answer

   Answer : B
   Explain: HTTP (Hypertext Transfer Protocol) is a protocol used for exchanging information over the internet. It is like the delivery boy which delivered the website, text and video etc.
8. Which is called the heart of the OSI layer.
   1. Data Layer
   2. Physical Layer
   3. Application Layer
   4. Transport Layer
   Show Answer

   Answer : D
   Explain: The Transport Layer (layer 4) is also referred to as the Heart of OSI. This is the layer where the actual transmission between different device occurs. If data error then re-transmit it.
9. ISO stands for ?
   1. International Standard Orgnization
   2. International Orgnization for Standardization
   3. International Orgnization for settlement
   4. Internal Orgnization Standard
   Show Answer

   Answer : B
   Explain: OSI stands for Open Systems Interconnection. It has been developed by ISO – 'International Organization for Standardization', in the year 1984. It is a 7-layer design in which each layer perform their own function.
10. Which cookies are temporary and are deleted when the browser is closed ?
    1. Data Cookies
    2. Third-party cookies
    3. Zombie cookies
    4. Session cookies
    Show Answer

    Answer : D
    Explain: Session cookies. Session cookies, also known as 'temporary cookies', help websites recognise users and the information provided when they navigate through a website.
11. In a star topology, how are devices connected ?
    1. Devices are connected in a circular chain.
    2. Devices are connected to a central hub or switch.
    3. Devices are connected to each other in a mesh-like pattern.
    4. Devices are connected using wireless signals.
    Show Answer

    Answer : B
    Explain: Star Topology, device (node) are connected with centeral hub or switch. If centeral device ( hub or switch ) fail , network fail.
12. Which device is known as dump device ?
    1. Hub
    2. Repeater
    3. Switch
    4. Router
    Show Answer

    Answer : A
    Explain: Hub device is known as dump device because they don't have proper address where data need to send. They go to all over network ask everyone 'is this is your data' then go to next if not that. It has not there own intelligence.
13. In a bus topology, if one device fails, what happens to the rest of the network ?
    1. The entire network goes down.
    2. Only the devices on the same segment as the failed device are affected.
    3. The failed device automatically repairs itself.
    4. All devices in the network become more efficient.
    Show Answer

    Answer : B
    Explain: Bus topology is a horizontal ( single line) topology in the network. It is the simplest physical orientation of nodes in the network. This topology is most used in local area networks and connected with cable.
14. Which topology is known as Interconnected topology.
    1. Star Topology
    2. Bus Topology
    3. Mesh Topology
    4. Tree Topology
    Show Answer

    Answer : C
    Explain: In Mesh Topology, every node has a dedicated point-to-point link between each possible node.
15. In which channel, the flow of data is in both directions at a same time ?
    1. Half Duplex
    2. Full Duplex
    3. Simple Duplex
    4. None of above
    Show Answer

    Answer : B
    Explain: Full Duplex, the flow of data is both side at a same time. Example : mobile phone etx.
