What an efficient and unique way to use computers. Virtualization is an abstract concept that uses one host computer to run multiple computers on that same computer, but each virtual computer views itself as a separate entity. It thinks it's physical therefore it can run it's own apps and operating systems. That is so neat. To use abstraction of computers, their full capacity, instead of limiting the power of a computer to some physical piece of "gear" (as mentioned in the lectures.)
Businesses can use virtualization to cut down on cost, portability, faster times, etc. It's obviously the better choice to use for businesses that need more room, faster speed and flexibility in large businesses. Virtualization seems like a concept made specifically for business, and I could also see it coming to use in the scientific and mathematical world.
This Website breaks down virtualization. Why you should use it, the benefits (featuring snapshots), the challenges, hardware used and the much appreciated humor. Businesses can benefit from this site along with learning and implementing virtualization. It would improve their work space which computes to an increased profit.
Security for your computer is like taking care of your home or family. Essentially it is taking care of yourself. You send and receive so much information through your computer, such as e-mail, documents, the Web sites you go on and the passwords you store. The risks of identity theft, hacking, viruses, worms (programs that do not require humans to copy themselves and which take up your computers resources), wireless interception with faulty wifi networks are serious to the safety of your information and your personal life. Protect yourself by:
Getting a firewall
Change the default settings on your wireless network
Don't jump on anyone's network because it is open
Password protect your data (maybe use 1password to store it all)
encrypt emails to ensure documents are safe
Be aware that your information and hardware can be hacked, stolen
Most businesses thrive on computers. Their budgets, supplier lists, payroll, government documents, fiscal year reports, customer identifications, etc. are all listed within their databases. It is crucial for businesses to take precautions to ensure that their company is not at risk for being hacked and their customers information is safe. If the customers find out that their info is being freely handed out to call lists or other sources, the companies credibility and business will decrease. People value privacy above all in their lives. It is in the company's best interest to understand security risks and deal with them efficiently and effectively.
This Brazilian company had information leaked when sending emails to its board members. Although it didn't directly effect their market stock value, they realized how important it was that information stay within their board members and company. So, they started to use a secure email service to ensure privacy and that their information stays safe. This is a link to the article.
The Internet is pretty much straight forward for the average college-age person. We have been using programs since we were in elementary and middle school. Namely instant messenger and games like the Oregon Trail. So, when Google brought the world wide web to our feet, and social networking connected every youth, the Internet was just another tool that could easily be figured out. Therefore, we have used the Internet for various research papers, social networking, projects, entertainment, etc for years, so most people know what it is.
However, it is refreshing to find out background facts about the Internet like the structure of the Internet (the inner core, outer periphery and mantle) while understanding fully our precious Wifi (commonly mistaken as wireless fidelity) we need to work as we sip our mediocre lattes at Starbucks and call each other hi-tech.
Keep it relevant to the audience -they are the priority
Use big text and good graphics (not clip art, and not teeny pics)
Have your signal (the message) louder than the noise (the graphics or add-ins)
Do not drone on, keep your audience engaged.
Keep design principles in mind (e.g. white space)
For business effective presentations help:
To sell a product
Gain a partner
Pitch an idea, sales plan or campaign to the big bosses
Expand the company effectively and efficiently
It may engage the company in growth for a fiscal presentation
Presentations are used in business constantly. It is a form of communication of ideas and information. The key is to be effective and engaging. A person needs to be effective ( sell the product) and efficient( a great presentation). One is the means and one is the end. Both are needed! Presentations are a tool to seal the deal or to communicate with the company. Do not be a drone!
All of the concepts presented this week in lecture were clear. I am a multimedia journalist. Let's face it, every journalist today must be, or will be in the future. Especially the photographers. I am photojournalist first and foremost, however, I have to be adept at videography, audio and putting journalistic multimedia packages together for the Web. The College of Journalism and Communications just recently just opened its multimedia portal for students called CMIR.
I normally upload my photographs in iPhoto, however I want to get Aperture and I have heard great reviews on Adobe Bridge as well. So, I may switch over. I edit in Adobe Photoshop, which you can buy as a student and get the student discount. The format I mainly use is jpg. Even though it is a lossy format, which compresses the image and loses a little bit of data every time, it is still the standard format in the photojournalistic world. For audio Audacity is a great, free software program. I have used it many times to edit audio for slideshows, to make recordings and to produce some great audio for my multimedia projects.
In video I am the least proficient, so it was interesting to learn about the inter-frame compression. This is a lossy format that transfers only the moving data from frame to frame. It is quite efficient because it does not transfer that static pixels. If there is a stationary object, and someone jumping around. The pixels are not moving around the stationary object so they are not transferred but the jumper is. It is called macroblocked. Only one block of moving data is transmitted. This helps in sending compressed videos. Also, the standard now is to save your videos with the H.264 format so that it can be viewed more easily on mobile devices. Let's face it, we are a mobile world and businesses are mobile as well. So, you must cater to clients and partners who want to view your videos with ease.
Businesses rely on multimedia heavily. If it is only a slideshow on their web site or a commercial slot in the SuperBowl multimedia represents a company in today's world. It shows who they are, it can demonstrate a product, aid in a presentation, land that giant client or allow them to expand their markets. The journalistic world relies on multimedia now more than ever. Our world is compressed just like the photos, video and audio because of the way we share things through multimedia. Think if the news didn't use multimedia. We would still be sitting down every morning to go through the print newspaper. Multimedia enhances our productivity and allows us to reach across the globe.
The Video above demonstrates what multimedia is. You have probably already watched it, but I thought it was useful to demonstrate all the amazing things that can come out of just photos, video and audio.
A function in Excel is a mathematical formula that quantifies large groups of numbers or whatever are in the cells (could be text). The function can be modified relatively or absolutely for the other cells giving the person control of their data. Functions range from basic count functions, date functions, to stats and financial functions.
The functions allows the business person to come to conclusions about the mass of data that is laid out in the spreadsheet. Depending on the function the businesswoman/man can achieve their goals of the quarter, for sales, for pleasing the customer through statistics, or just keeping a firm grasp on where they are at financially so she or he knows when to invest and when to wait out a recession let's say.
The functions in Excel allows business people to function optimally in their environments. It provides essential and interesting data if you take the time to learn how to use them.
The concept I found the most interesting and clear was web-based software. Yes, everyone uses packaged software and some of it is discounted for students, but realistically more often than not it is bootlegged. For example, Adobe Creative Suite encompasses InDesign, Photoshop, Dreamweaver, Flash, etc. These are applications that most students from the College of Journalism use constantly, therefore for the their own comfort they transfer it onto their computer from another and essentially break the EULA agreement (recently some people are having a difficult time with Rosetta interacting with the bootlegged copies because they have updated their computer). It happens all the time, especially because Adobe is constantly updating itself once every year or two years if not sooner.
So, I think that web-based software applications are more accessible for businesses and students. Especially students graduate and decide to start their own businesses. They can no longer get away with using a fake serial number to boot up the software, therefore, in the cloud services allows them to take things global, manage it from anywhere, cut out the cost of systems of engineers and run successfully globally.
Here is a linkthat describes "the clouds" business. The media has used the phrase so often it has become a household description of what web-based software is that has info on remote servers.
One of the most interesting things about this week was the parts of the computer section in the personal computer videos. Personally, I focused on software in all my computer life rather than the hardware behind it. The Central Processing Unit was the most interesting part I think in it's capabilities and functioning speed.
The CPU is the "computer's brain," but computers can have GPUs, Graphics Processing Unit, so it is not the one and only. The CPU performs computations based on clock speed. Clock speed is a signal that beats on a regular basis, like your heart. The clock speed can be a repetitive signal a billion times a second. And if you increase the clock speed on the computer then you can increase the amount of work that gets done. The CPU can have different processing cores such as dual, quad or Intel's turbo boost all on the same chip. So, multiple units on one core chip. Compare CPUs in a chart updated daily!
The CPU has a little space on the chip to house a cache, which is ultra fast memory, ready to use at any moment by the computer when it encounters frequently used memory or information. So, less time for you to wait on the CPU and the constant clock. The CPU is like a clock, it has multiple parts that all synchronize together to maintain a machine for a person to utilize.
Let's get down to business: In the business world, time is money. Both are valuable. Therefore choosing the right computers for your business or the business you work for is extremely important. You can improve productivity while reducing the time it takes, and therefore cost. Choosing the right CPU to fit the businesses needs is important. You have to weigh increased speed vs. the heat it gives off and how many cores will get the job done for the business. Computers are an asset that all businesses use and need. It is important to understand them and utilize them correctly to maximize profit.

Copyright
It sounds daunting and should b bolded in red, however it is a simple concept to grasp. The laws surrounding it can be complex, but copyright in itself is the protection of the author and his or her work. U.S. copyright laws protect most forms of creative expression. Meaning books, music, photographs, video, etc. are all protected under a copyright. In order to use someone else's work you must get permission in writing, be the owner flat out or get it in a public domain. Take Flickr, a photo database online, for example, it has several copyright restriction categories. Some are public domain and can be used by everyone. But some photographs cannot be manipulated and some photographer require an attributed link if their work is shown. For artists and owners of creative expression copyright is the only thing that validates their work in the legal realm. It is a respect for their intellectual property to follow the copyright laws and use their work accordingly.
Business purposes:
Copyright is extremely important in business to protect their product or the products of others. Also, because of one employees mistake the business owner does not want to get sued for copyright infringement. In order to profit from a business, the product has to be protected. One of those ways is making sure copyright infringement does not take place. Business thrives off of creative expression and incentive and strict copyright laws gives way to both of these things.
Try This:
This is a website that shows you how to embed the copyright symbol in your images, graphics, etc. So when someone decides not to follow these rules, still protect your creative expressions!
