Complete Question:
1. A wireless technology standard for exchanging data over short distances
2. A particular brand of mobile phone/PDA
3. A network that operates over a limited distance, usually for one or a few users
1. Bluetooth
2. PAN
3. Blackberry
Answer:
1. Bluetooth 2. Blackberry . 3. PAN
Explanation:
1. Bluetooth is a wireless technology standard, used in order to exchange data between mobile devices, like smartphones, tablets, headsets, wearables, over short distances in a one-to-one fashion (which means that it is not possible to build a network based in Bluetooth).
2. Blackberry is a brand of mobile phones/PDAs, very popular a decade ago, because it was the first one to allow mobile users to access e-mails and messages from anywhere, at any time.
3. PAN (Personal Area Network) is an ad-hoc network that it is only available for data exchange at a very short distance, within the reach of a person, i.e. a few meters as a maximum.
It is thought to allow someone to interact with his nearest environment (laptop, tablet, PDA) and it can be wireless (like Bluetooth) or wired (via USB cables).

You can measure it by the amount of automatisation. The bigger technological process the easier it is to automate systems.
Question:
To mitigate the effects of most of the common network threats including disruption, destruction and disaster, companies are beginning to migrate their servers, networking devices and data into professional datacenters. This is called
A) Colocation
B) SAAS
C) Peering
D) Clustering
E) Server Farming
Answer:
The correct answer is A) Colocation
Explanation:
Colocation as already defined is the voluntary relocation of all network facilities to a data centre so as to reduce the risks of disaster, disruption, destruction, intrusion whilst increasing security, flexibility and scalability at a lower cost.
As the world gets more digitized, datacentres are getting more patronage. The sales figures show this.
