In today's lesson I learnt how to download an operating system, I downloaded Windows 7 operating system from Dreamspark (https://www.dreamspark.com/)
Dreamspark is a program provided by Microsoft to provide students with software design and development tools at no charge.http://en.wikipedia.org/wiki/DreamSpark
I then installed virtual box, this creates a virtual partition on a PC.
Oracle VM VirtualBox is a virtualization software package for x86 and AMD64/Intel based computers. It was created by innotek GmbH, purchased in 2008 by Sun Microsystems, now developed by Oracle. It is installed on an existing host operating system as an application; this host application allows additional guest operating systems, each known as a Guest OS, to be loaded and run, each with its own virtual environment. http://en.wikipedia.org/wiki/Virtual_box
I then installed the Windows 7 Operating System on the virtual box. This allowed me to install an operating system without compromising my PC.
We also learnt about the internet of things:
The internet of things is a network of connected devices, this can be improved in the future by having thin client low power embedded devices such as lights could have these devices inside to be able to text your lights to switch them off. There is a start to this already through the new British Gas 'Hive Active Heating' where you can control your heating anywhere and anytime from your mobile, tablet or laptop. http://www.britishgas.co.uk/products-and-services/hive-active-heating/how-to-use.html
The internet of things refers to uniquely identifiable objects and their virtual representations in an internet-like structure. If all objects and people in daily life were equipped with identifiers, they could be managed and inventoried by computers. Besides radio frequency identification, the tagging of things may be achieved through such technologies as near field communication, barcodes, QR codes and digital watermarking.
Equipping all objects in the world with minuscule identifying devices or machine-readable identifiers could transform daily life. E.g. Business may no longer run out of stock or generate waste products, as involved parties would know which products are required and consumed. A person's ability to interact with objects could be altered remotely based on immediate or present needs, in accordance with existing end-user agreements. http://en.wikipedia.org/wiki/Internet_of_Things
I also learned about ARM based devices:
ARM is a RISC-based computer design approach, this means ARM processors require fewer transistors than in average computers, this reduces cost, heat and power usage. http://en.wikipedia.org/wiki/ARM_architecture
Primary components in a typical PC:
Functional motherboard, Fast processor, Storage, Sound Card, CD-ROM/DVD player, Graphics card, speaker system etc.
Secondary components in a typical PC:
Video capture card, large amount of system RAM, High capacity hard-disc, CD-R/W/DVD, SCSI expansion card, Digital interface for audio, digital mixer, PCI network card, scanner, TV in/out.
