1. Explain in detail:
The Internet of Things (IoT)
According to Techopedia, the Internet of Things (IoT) is a computing concept that describes a future where everyday physical devices connect to the Internet and are able to identify themselves to other devices.

The IoT is holds great significance because an object that can represent itself digitally becomes something greater than the device by itself. Once this occurs, no longer does the object relate just to you, but is now connected to nearby devices and database data. When many devices are joined together, they are known as having "ambient intelligence."
Examples of Internet of Things (IoT)
Many of us think about being connected in terms of computers, tablets and smartphone and the unlimited …show more content…
Define and describe SNMPv3. How it is different from SNMPv1 and SNMPv2.
According to Stalling and Case, Simple Network Management Protocol (SNMP) is a widely used network monitoring and control protocol. Data are passed from SNMP agents, which are hardware and/or software processes reporting activity in each network device (hub, router, bridge, etc) to the workstation console used to oversee the network.

In other words, this protocol allows for the identification of issues in the network hardware/software before they become major problems. SNMP allows multiple devices to communicate each other in order to prevent major maintenance issues. SNMP uses OID (Object Identifiers) to defined what can be monitor in different devices. It also uses MIB (Management Information Base) a system in place to monitor the different devices.

According to Techopedia, SNMP has evolved into three different versions:
SNMPv1: This was the first user friendly implementation, operating within the structure management information specification, and described in RFC 1157. It had very weak security features.
SNMPv2: This version has improved support for efficiency and error handling and is described in RFC 1901. It was easy to monitor, but once again its security capabilities was weak as it lacked authentication or encryption

...which are the taxpayers of Lafayette County. In bringing in new software when he was appointed to the office, Chip replaced the outdated program that was being used. While some of the staff did not like switching from the software because it was new, it was much more efficient than the previous one. The previous software required the vehicle information (year, make, model, series, motor, and other options) to be manually entered to reach the assessed value. The new software was much more efficient as it automatically put in the information based on the vehicle VIN. For Chip, this switch was a "no brainer." The new software is on the state approved vendor list, and allows his employees to be more efficient because information is entered faster, and there is less chance for error since the information is decoded by the VIN. This is a benefit to the public, as their property is more accurately assessed. 4. Motivation may be defined as the psychological processes that arouse and direct goal-directed behavior. Motivation is what pushes us to accomplish a goal. The human mind is geared to setting an objective and then obtaining it because there is an internal drive for satisfaction, or there is an external factor, such as requirements to maintain employment, that drives us to complete a task to gain a reward that we desire. This drive is the unseen force called motivation. Chip motivates his employees in a couple of different ways, very similar to how he sets goals in the goal setting...
