What is cloud computing?
Cloud computing means that your computer is stored remotely
Cloud computing is the provision of computing services over the internet. These services are accessed by the user locally on the hard drive of the user's computer
Cloud computing is the provision of computing services over the internet. The data and applications provided are accessed by the user remotely from the host company's servers.
Cloud computing is the provision of computing services over the internet. The data is stored remotely on the network of the user.
Cloud storage can be provided as a service by allowing your data to be stored...
remotely on the host company's servers
remotely on your local computer
locally on your network
locally on your remote computer
An advantage of cloud software is that...
It is always free
It cannot be hacked
It is updated automatically
It is only ever stored locally on your computer
A disadvantage of cloud storage is that..
Your data will always be hacked because your data can be accessed from any device with an internet connection
Your data is vulnerable to hacking because your data can be accessed from any device with an internet connection
Your data can easily be hacked because there is no system security provided by the host
Your data is vulnerable to hacking because it is stored locally on your computer
An advantage of cloud storage is...
It is not possible for hackers to breach the host's security
Backups are stored locally on your computer
Security is managed by your own IT staff
Security and backups are managed by the host company
A disadvantage of cloud computing is...
You need an internet connection to access the data or software
You need an internet connection to access your LAN
You cannot use a device that is connected to the internet
You need local storage to manage the data backups
