What is a local area network (LAN)?

• A network that connects devices in a small geographic area, such as a home or office

• A network that connects devices over a large geographic area, such as a country or continent

• A network that connects devices using wireless technology, such as Wi-Fi or Bluetooth

• A network that connects devices using storage devices, such as hard disks or flash drives

What is the difference between an intranet and an extranet?

• An intranet is a private network that is accessible only to authorized users, while an extranet is a public network that is accessible to anyone

• An intranet is a public network that is accessible to anyone, while an extranet is a private network that is accessible only to authorized users

• An intranet is a private network that is accessible only to users within an organization, while an extranet is a private network that is accessible to users outside the organization

• An intranet is a private network that is accessible to users outside the organization, while an extranet is a private network that is accessible only to users within the organization

What is the advantage of a star topology over a bus topology?

• A star topology is more scalable and reliable, as adding or removing devices does not affect the rest of the network and a single device failure does not bring down the whole network

• A star topology is more efficient and secure, as data is transmitted directly from the source to the destination and no other devices can intercept the data

• A star topology is more flexible and cost-effective, as devices can be connected using any type of cable and the network requires less hardware and maintenance

• A star topology is more simple and easy to set up, as devices are connected to a central hub or switch and the network does not require any configuration or management

What is the difference between a physical topology and a logical topology?

• A physical topology is the actual layout of the devices and cables in a network, while a logical topology is the way the devices communicate with each other in a network

• A physical topology is the way the devices communicate with each other in a network, while a logical topology is the actual layout of the devices and cables in a network

• A physical topology is the theoretical design of a network, while a logical topology is the practical implementation of a network

• A physical topology is the practical implementation of a network, while a logical topology is the theoretical design of a network

What is the standard for wired Ethernet networks?

• 802.11

• 802.15

• 802.16

• 802.3

What is the standard for wireless Ethernet networks?

• 802.11

• 802.15

• 802.16

• 802.3

What is the difference between a peer-to-peer network and a client/server network?

• A peer-to-peer network is a network where all devices have equal roles and responsibilities, while a client/server network is a network where some devices act as servers and provide services to other devices that act as clients

• A peer-to-peer network is a network where some devices act as servers and provide services to other devices that act as clients, while a client/server network is a network where all devices have equal roles and responsibilities

• A peer-to-peer network is a network where devices communicate directly with each other, while a client/server network is a network where devices communicate through a central server

• A peer-to-peer network is a network where devices communicate through a central server, while a client/server network is a network where devices communicate directly with each other

What is the difference between a thin client and a thick client?

• A thin client is a device that has minimal processing power and relies on a server for most of its functions, while a thick client is a device that has sufficient processing power and can perform most of its functions independently

• A thin client is a device that has sufficient processing power and can perform most of its functions independently, while a thick client is a device that has minimal processing power and relies on a server for most of its functions

• A thin client is a device that has a small form factor and consumes less energy, while a thick client is a device that has a large form factor and consumes more energy

• A thin client is a device that has a large form factor and consumes more energy, while a thick client is a device that has a small form factor and consumes less energy

What is virtualisation?

• The process of creating multiple virtual machines on a single physical machine, each with its own operating system and resources

• The process of creating a single virtual machine on multiple physical machines, each with its own operating system and resources

• The process of creating a virtual network that spans across multiple physical networks, each with its own topology and architecture

• The process of creating a physical network that spans across multiple virtual networks, each with its own topology and architecture

What is cloud computing?

• The delivery of computing services, such as servers, storage, databases, networking, software, analytics, and intelligence, over the internet

• The storage of data and files on remote servers that can be accessed over the internet

• The use of web-based applications and software that run on a browser and do not require installation on the local device

• The creation of online communities and social networks that allow users to share and collaborate over the internet
