P5

A local delivery company have been allocated money to improve their service.  Some of the money has been put aside for mobile technology approx. £500 per driver.  Make suggestions to the director of how he can spend the money, to make the delivery service more efficient.  Give examples how the mobile technology will help the business.

I think the company could put the money towards purchasing a phone specified for work. For example possibly an IPhone, this is so the driver could use the built-in GPS/Satnav, this could help the van-driver with his deliveries and directions to the destination. The Owner of the company, or whoever is in charge, could use the GPS to track the van-drivers to make sure that they are doing their deliveries and not slacking on the job.

How do devices and protocols keep data safe?

Most up to date devices can keep the majority of data safe, as they are very clever and they don't take a genius too work.
You can set your own password for security/protection.
On an iPhone you need a 4 digit code too unlock it that the owner can set. This can be very awkward and hard too guess as there are thousands of possibilities and the phone locks for 10+ minutes after ten wrong attempts.
On the iPhone you can download tracking devices and has a built in Satnav, this could be used too track your stolen phone.

On other phones like blackberries, you can set the password too whatever you like, including letters, so there will literally be billions upon billions of possibilities too keep your data safe.
You can also download tracking data and Satnav type apps on your blackberry too track a stolen phone etc!
Most Smartphones now-a-days can do things like this as they are clever devices!

There is also something called encryption; this is the process of sending a message privately so hackers and eavesdroppers cannot read it.

If a photographer went out and wanted too transfer a picture, you would need too locate a hotspot. If you connect too the hotspot you can send it by email. If you have 3G or 4G on your phone that's very helpful. 3G is third generation of mobile standards, this allows you too go on the internet where-ever you are. You can also send the photo's through a social networking system for example, tumblr or facebook/twitter.
You could also send it through SMS with the disadvantage of it costing.
