Devices
“A component that allows a computer to connect physically to a network.”
Network Interface Card (NIC) / Ethernet adapter
“A component that receives packets from a device and then sends those packets to every device attached to it.”
Hub
“A server that stores files for access by any device on the network.”
File server
“A server that stores emails and allows users access to their email account to read, write and reply to emails.”
Mail server / Email server
What type of network connects devices across small, limited geographical areas like homes, offices, or schools?
LAN
“A component that allows a computer to connect wirelessly to a network.”
Wireless Network Interface Card (Wireless NIC / Wi-Fi adapter)
“A component that records the address of the components attached to it as it receives signals from them. When it receives a packet, if the address is known, it is sent only to that device.”
Switch
“A server that stores websites for access over the internet.”
Web server
“A server that manages the print queue for a printer.”
Print server
Which cloud service category delivers ready-to-use software applications to end-users over the web?
SaaS
“A component that receives a signal and sends it on so that the signal does not degrade.”
Repeater
“A component that sends and receives wireless signals; it is usually attached to a hub, switch or router.”
Wireless Access Point (WAP / Access Point)
Which cloud service category offers pre-configured platform environments and runtime tools specifically designed for developers to build software?
PaaS
“A server that allows clients to connect to upload and/or download files.”
FTP server / File Transfer Protocol server
Which cloud service category provides core infrastructure, such as host servers and network resources, for businesses to build upon?
IaaS
“A component that connects two network segments into one network.”
Bridge
“A component that joins two similar networks; it receives packets from one network and sends them on to the next network in the direction of the destination.”
Router
“A physical server that acts as many different servers to potentially different clients. Clients think they have a dedicated hardware server.”
Virtual server
“A server that handles requests to access and manipulate data, and then performs the processes required on the data.”
Database server
“This can be physical or software based. It monitors incoming and outgoing signals to make sure they meet the criteria.”
Firewall
“A component that joins two dissimilar networks; it converts packets from one network into an appropriate type for the next network.”
Gateway
What hardware element inside a router contains the IP address information needed to dynamically determine data packet paths across networks?
Routing-table
What spatial phenomenon occurs at cell boundaries in mobile networks that causes signal reception quality to drop and transmissions to delay?
Interference (or Attenuation)
“A server that sits between a user and a web server (or other server). It can act as a firewall by checking if requests to the web server meet the criteria and blocks those that don’t.”
Proxy server
What primary medium connects users to all three cloud computing service models?
Internet
