They cannot have downtime whilst they perform updates. Engineers will often be experts and highly experienced
d)
RAM - memory - apps at the same time
64.
Virtual Machine
a)
Connect computers or devices together using Bluetooth or Wi-Fi For instance, a phone could connect to an in car entertainment system to play music and make hands free phone calls. These networks have a range of a few meters. Devices need to be paired for security
b)
Emulates a computer inside another computer. The VM has virtual hardware. It can have a different operating system. e.g. a Mac could run Windows inside a VM. This is called a guest operating system. If the guest operating system crashes, it won't affect the main operating system and other virtual machines
c)
Creates a safe, encrypted connection over a less secure network, such as the public internet.
d)
Cloud services need a fast and reliable Internet connection to work. If a computing task is complex it may be faster for it to happen on a user's machine. The type of device used will limit what software can be run
65.
Speed of cloud installation
a)
Will need to purchase software
b)
No need to purchase servers and hardware
c)
City locations normally have faster internet than rural ones. The cost of installing infrastructure such as fibre cables can be shared by many customers if the population is denser
d)
Cloud servers and storage are much faster to get working due to the use of virtual machines
66.
Cloud performance
a)
Are buildings that are dedicated to storing computer servers
b)
Wired Equivalent Privacy is a form of security and protection where a password key is used
c)
You should only connect to Wi-Fi that uses WPA2 encryption. Alternatively, you could use a virtual private network (VPN) which encrypts everything between you and the VPN provider
d)
Cloud services need a fast and reliable Internet connection to work. If a computing task is complex it may be faster for it to happen on a user's machine. The type of device used will limit what software can be run
67.
Eg A smartwatch won't be able to run a complicated 3D game
a)
It is important that cloud service providers are storing data securely
b)
Allows the same files to be copied to multiple devices via the cloud. The files are also backed up to servers on the cloud. Products that support file synchronisation•Microsoft OneDrive•Google Drive•Dropbox
c)
Eg A smartwatch won't be able to run a complicated 3D game
d)
•Mobile phone - touch screen, fingerprint scanner, multiple cameras, vibration•Tablet - SSD storage, high resolution displays, long battery life, virtual keyboard, touch screen -Television - high quality (HD and 4K), streaming, on screen guides, control from mobile device •Digital assistant - voice controlled, in built speaker, network/Internet connected
68.
Disaster recovery policies
a)
Software requires an organisation to make backups of their data. They often need to employ someone to take on this responsibility. Backups will usually be made daily
b)
Organisations need to plan for how they can recover systems and data in the event of a disaster. Backups of data need to be available. Hardware and alternative premises may also need to be purchased and rented. Cloud software and data is stored at remote locations. It is usually easier to restore in the event of a disaster
c)
City locations normally have faster internet than rural ones. The cost of installing infrastructure such as fibre cables can be shared by many customers if the population is denser
d)
Is an ad hoc wireless access point that is created by a dedicated hardware device or a smartphone feature. It shares the phone's cellular data. Other nearby devices can then use the shared hotspot to connect to the internet
69.
Cloud data backups
a)
Cloud service providers often make backups of data as part of their service. In some cases they may charge extra for this service, or extra for higher quality backups
b)
Hard disk technology (magnetic / SSD) - storage.
c)
RAM - memory - apps at the same time
d)
Wired Equivalent Privacy is a form of security and protection where a password key is used
70.
Offline data backups
a)
The process of initiating contact between two Bluetooth devices and allowing them to communicate with each other.
b)
Second-generation mobile phone service, popular in the 1990s. 2G was the first standard to use digital transmission, and as such, it paved the way for texting and media downloads on mobile devices.
c)
Software requires an organisation to make backups of their data. They often need to employ someone to take on this responsibility. Backups will usually be made daily
d)
Poor signal can reduce access to the internet, Devices can disconnect if they use Bluetooth and are too far away, Many devices sharing a connection can make it very slow
