You may have to do some digging and some synthesis to effectively respond to the questions I ask.

PART A

Week 3 Questions: 

This week we’re talking about application of MIS Infrastructure; Networks; and Mobile Computing. It seems like a lot to cover in one week . . . but as I would remind you, this is an accelerated course! So, here are our discussion questions for this week. I would recommend that you pick one of these areas (that has not been covered already) and focus on it

MIS Infrastructure

• What is an “agile” MIS infrastructure?
• What are its key characteristics?
• What steps can an organization take to ensure it has one?

PART B

I need a reply/response to these discussion board answers. Just read the discussion board answers, and respond to the information you read and also add your own point of view in each discussion board answers. Just three to five Lines response each. Please I need good and quality response to these discussion board answers.

IT Security

Security is the ability to resist malicious and unauthorized attacks that attempt to breach crucial confidential information or gain control of the systems, while still providing services to authorized users. One important  IT  infrastructure that every business should have is IT  architecture.IT security provides the protection of software, hardware and the network of the organisation. It defends the sensitive information and the organisation by preventing dangers posed by the unauthorized attacks delivered via the internet through the use of hacking, viruses, and Information can be protected only if the IT security is strong enough to handle the malicious attacks. IT security is a basic requirement because worldwide computing is essentially insecure.

What’s the difference between cloud computing and grid computing? To what degree may they be similar?

Cloud computing is defined as a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources such as networks, servers, storage, applications, and services that can be rapidly provisioned and released with minimal management effort or service provider interaction. However, grid computing is defined as a form of distributed computing that involves coordinating and sharing computing, application, data and storage or network resources (Seyyed Mohsen Hashemi, 2012).

There is a difference between cloud computing and grid computing on numerous levels. When it comes to ownership, Grid computing can have multiple owners while cloud computing has only one owner. Cloud computer offers more services than Grid computing. Also, Cloud computing eliminates costs and complexity of buying, configuring and managing the hardware and software that are needed to build applications since the applications are delivered as a service over the internet; which is not the case with grid computing.

When it comes to similarities, both cloud and grid computing are scalable; they both have multitask functions and are SLA based when it comes to service negotiation (Seyyed Mohsen Hashemi, 2012).

Three alternative wireless technologies are:

Wi-Fi: uses radio waves (RF) to allow two devices to communicate with one another. The technology is most commonly used to connect Internet routers to devices like computers, tablets and phones; however, it can be used to connect together any two hardware components. Wi-Fi is a local wireless network that runs of the 802.11 standards set forth by the Institute of Electrical and Electronics Engineers. The Wi-Fi Alliance certifies some products, allowing them to be labeled as “Wi-Fi Certified.” In order to receive that designation, and product must go through the Alliance’s interoperability certification testing.

Bluetooth: are wireless technologies used to transfer data over short distances. The technology is frequently used in small consider devices that connect to users phones and tablets. For instance, the technology is used in many speaker systems. Bluetooth Low Energy uses less power than standard Bluetooth and is used in hardware such as fitness trackers, smart watches and other connected devices in order to wirelessly transmit data without heavily compromising the battery power in a user’s phone.Bluetooth uses UHF radio waves for data transfer. The technology was originally standardized as IEEE 802.15.1, but the IEEE no longer maintains that specific standard. Companies that work with Bluetooth are often affiliated with the Bluetooth Special Interest group (SIG). The group currently has over 20,000 members, and must certify a product before it can be marketed as a Bluetooth device to the consumer or business market. That certification helps ensure that all Bluetooth devices work in a standardized way and provide a similar experience for consumers.

Wi-Max: stands for Worldwide Interoperability for Microwave Access. This wireless technology allows data to be transferred at a rate of 30-40 megabits per second. The term refers specifically to interoperable implementations of the IEEE 802.16 wireless family. The Wi-Max Forum certifies devices before they can be sold to consumer or businesses. The technology can be used both indoors and outdoors, however, Wi-Max devices typically produce a better signal when used outside or by a window
