Week 6 Required Readings

In sum, EbscoHost and Journal of Academic Librarianship are gateways to thousands of e-journals that are published and houses articles on its website for colleges and universities. The articles are presented for research and the researcher's findings. Articles are accessed expeditiously and are quite legit and thorough. Librarians can take control of their e-journals list with an electronic journals service (EJS). Therefore, information is or can be managed.

The RFID refers to "radio Frequency identifier" and consists of a computer chip and antenna. It is similar to a barcode that is read with electro-magnetics. These chips carry much information, and in the near future, will probably be much smaller, yet even more powerful. (As an example, the City of Cleveland where I currently reside apparently utilizes an RDID tag which captures a photo of a speeding automobile or vehicle in a certain area, during certain hours of the day. This RFID can capture the photo from several feet away! If your vehicle is photographed, the registered owner will receive a speeding ticket via postal mail which you are required to fulfill. You will find a similarity along the interstate highways as well!)

There are several common types of computer networks listed below:

• Personal Area Network (PAN)
• Local Area Network (LAN)
• Campus Area Network (CAM)
• Metropolitan Area Network (MAN)
• Wide Area Network (WAN)
• Global Area Network (GAN)

The most commonly used is the local area network utilized in homes, offices, hospitals, schools and the personal area network. However, since the 70s, high speed internet service has become a necessity. Grouping computers makes a computer network. Network topology makes reference to the way the network system interacts and relates, one with another. Two or more networks are classified as the internetwork. Bridges are the links we use to connect multiple network segments. A network design ranges from simplicity to complexity. The design can contain one or more links (bridges), photos, animation, coloring of text and coloring of the background.......according to the installer or creativitist.

The YouTube video was not too legible in sound and could not be heard fluently without chopping and breaking up.

Assignment 3

I am so weary from trying so hard to complete Assignment 3. It is incomplete and probably incorrect, but I tried. I have two URLs:

http://www.citeulike.org/profile/cjw39/import_do
http://www.citeulike.org/user/cjw39

I am quite sure that I will have to redo this assignment, or complete it. It will probably say that there is nothing there even. I am only sending it in to show that I have attempted to complete assignment on time. Thank you, Dr. He, for your advice this afternoon. I was able to open Zotero and document, tag, etc. If it does not come out, I made a mistake somewhere. I will be in touch with you and with Wan. Have a wonderful evening. I'm leaving work now!

Week 5 - Multimedia Representation & Storage

After reading the required articles regarding data compression and its basics, I find Wikipedia to be quite informative on a layperson's level. Wikipedia defined "data compression" as an encoding of daa using less bits via specific encoding schemes. The sender and receiver must understand the scheme itself to use data compression. Compression means compact, in my words, and a reducing. Therefore, data compression reduces information, yet stores more. It is transferred in less time also as it stores more. It brings me back to the cliche that less is more. Data compression requires trade-offs in order to compress and decompress data.

Data compression basics on media does not require information theory, mathematics, or even programming. I learned that binary digits were bits. Information that is guaranteed (the same as its originality) is termed "lossless". Unguaranteed information (a wanna-be or a to be original text) is termed "lossy".

A new term for me from these articles is "run-length encoding". I think the breakdown of it is kind of simple and I see that sequence is unimportant here.

The last two articles could not be assessed; those pages could not be found as my personal laptop froze last night as I was in the Pitt Portal and Course Web. I was unable to submit this blog last night.

Have a pleasant weekend Cohort 8.5, Dr. He, and Wan (TA)
