(c) what Source C and Source D reveal about impacts of homeowners with IoT smart homes.
(d) With reference to the sources and your own knowledge, whether the use of IoT in smart homes is an incremental or transformational change.
Quantum computers encode in qubits instead of binary data. Where 8 bits in a computer can represent any number between 0 and 255, 8 qubits can represent those same numbers simultaneously. In research situations, quantum computers are able to examine a multitude of possible combinations and run a variety of simulations simultaneously.
will quantum computing impact research and development in academic environments?
Can digital technologies be used sustainably?
Many organizations claim that the most efficient use of information technology (IT) equipment, such as laptops and printers, is to replace them on a regular basis. For example, an organization’s strategy may be to do this every three years.
Other organizations purchase IT equipment that can easily be upgraded by increasing the storage and memory or upgrading the processing capabilities only when required. They claim they do not need to replace their IT equipment on such a regular basis and believe this is a more sustainable practice.
the sustainability of these two strategies.
Source A
Source B Through this article today, we are here to share with you the various challenges in the internet of things. Security challenges- The first and foremost on the list of challenges is security. As the backbone of IoT is data storage and sharing, the biggest question arises about the security of data. Enabling every small physical object with the feature of sharing information may attract multiple raised brows. Lack of encryption- Encryption sounds like the ultimate answer to security issues. But hackers may manipulate these algorithms and turn a protective system into the most serious loophole. Lack of sufficient testing and updating- With the increasing market of IoT, production has to be faster. To compete in the race of production, manufacturers lack tests and updates. The main focus of IoT manufacturers now seems to be production, not security. Thus products lack proper and regular testing and updates. This makes IOTs prone to being attacked by hackers.
Source C A smart home is a household with internet-connected appliances you can remotely control using a tablet or smartphone. It uses smart devices such as smart TVs, smart thermostats, air conditioners, and even a robot vacuum. They are then connected together in a single network, through either hardwired or wireless systems like Zigbee, Wi-Fi, Bluetooth, and NFC, among others. Using the Internet of Things (IoT) technology, your smart appliances can communicate and share real time data with each other. This allows the devices to perform scheduled and automated tasks. IoT home gadgets bounce data back and forth with the use of sensors, learning and processing your patterns to automatically adjust themselves to your comfort. Some smart home Internet of Things applications are automatic light switches, burglar alarms, and voice-activated sound systems.
Source D A tired business person returns to their certified IoT smart home after a long working week. The smart security system senses they are alone and initiates the “Friday Night In” sequence. An intercom with a thoughtful, comforting voice suggests they might want to order in tonight. The business person unloads their things in the kitchen where the smart stove displays a selection of take-outs, rather than its default recipe guide. After the food arrives they retreat to the living room to watch some TV. The smart TV prepares a selection of Netflix marathons categorized by mood. They choose: “Looking to be cheered up? Comedy Playlist.” Before starting the program, they review a set of graphs displaying the data from their activity and diet throughout the day. A list of tips for smart living is generated, one of which reads that based on the number of consecutive nights spent alone, they might consider exploring a selection of popular dating sites instead of watching TV. With an inadvertent slip of their thumb the request is OK’d and instantly a set of profiles are displayed, each chosen from a generated list of their tracked preferences. A flurry of pings and messages from other stay-at-home hopefuls fills the screen. The smart home intercom exclaims, “You’ve got mail!” The confused and beleaguered business person fumbles for the remote and… uh-oh, the TV snaps a selfie in response to the flood of pings. Their image, sitting in their underwear eating noodles appears briefly on the screen before being whisked off into the ether. The flood of messages doubles, the system freezes causing the smart home to reboot. The house goes dark.
