  • Purchasing Computer Parts: OEM vs. Retail

    Purchasing Retail vs OEM Products

    Most people are not familiar with what an OEM is let alone what an OEM product is, these products are becoming more and more available to the consumer. This is due to a combination of the fast evolution of computer technology and online shopping. Some will say it is better to purchase retail only while others will say it is better to purchase OEM. Personally I agree with both; so I am going to fill you in on the differences and the benefits of each so you have the information you need to decide for yourself. Continue reading

  • Tablet vs Laptop

    A tablet is the sleek, stylish option for those who compute on the go. However, when considering this investment you should carefully consider the benefits and options offered by a traditional laptop and those offered by an innovative tablet.
  • Notebooks vs Laptops

    When considering a purchase of either a notebook or a laptop you may wonder what features can help you make your decision. Understanding the benefits of each machine can help you make an educated choice about which device will better suit your particular needs.
  • Netbook vs Notebook

    Both netbooks and notebooks are designed for on-the-go use; however there is a definite difference between the ultra-light design of the netbook and the more substantial design of the notebooks.
  • Netbook vs Laptop

    If you are in the market for a new computer and want to catch up with the times and ditch that dinosaur desktop that is in the corner, there are several options to consider. For many people the obvious transition from a desktop would be to purchase a laptop. However, with the introduction of the netbook, many consumers have a hard time determining which options are best for their needs. Consider these main differences to help choose the technology option that is right for you:
  • Thinkpad vs. MacBook Pro

    The Lenovo Thinkpad W-Series is a great new laptop contending with the ultra-popular Apple 15-inch Macbook Pro. Many are torn between Mac and PC, and these two laptops do not make that choice easy. Both were released last year with updates always in the works, of course. Both laptops have a lot to offer. But taking a side-by-side look at the two can help in making a decision between the two.
  • Versions of FireWire

    The original version of FireWire technology was released in 1995. IEEE 1394-1995 is now referred to as FireWire 400. It has 6 circuits, including 2 which provide the device with power. It has most often been used for desktop computers.

    Just 5 years later, the IEEE 1394a-2000 was released. This version of FireWire was meant to improve upon the original design. It offers faster bus reconfiguration, a suspend mode for conserving power, asynchronous streaming, and more. This version also made use of Sony’s development “i.LINK,” a 4-circuit connector.

    FireWire 800 came out in 2002. The IEEE 1394b-2002 was Apple’s 9-circuit “bilingual” version of FireWire. With backwards compatibility with slower versions, it used a new encoding scheme called “beta mode,” allowing data transfer speeds of 786.432 Mbit/s. With the bilingual connector, older devices could be hooked up to the new port.

    FireWire S1600 and S3200 were both announced in December of 2007, for release in 2008, though that didn’t exactly happen. They had been in the works for some time and were planned for in the IEEE Std. 1394b. The same 9-circuit beta connector was used as with the FireWire 800, for the new 1.6 Gbit/s and 3.2 Gbit/s. The goal? To compete with the USB 3.0, the fastest version of USB yet.

    The latest developments in FireWire development include a new port specification that adds compatibility with Ethernet technology. The same port can connect with either a IEEE Std 1394 (FireWire) or IEEE 802.3 (Ethernet device). Lastly, a single mode fiber, as a medium for data transport will add even more speed to FireWire. The goal for the near future is 6.4 Gbit/s speed and more connectors to enhance compatibility across technologies.
  • Huffman Code

    David A. Huffman was born August 9, 1925. He was made famous by his contributions to the field of computer science. His distinguished career began in graduate school, where he wrote his thesis called, “The Synthesis of Sequential Switching Circuits.”

    His professor at the time had been working extensively on a compression code, and was struggling with it. He offered the class the option of writing a thesis on a compression code. Huffman had made many attempts at developing an efficient code before almost giving up. At last, however, he developed what is now known as the Huffman Code, and wrote his thesis on that.

    Now hailed as the most efficient means of compression communication possible, this method was later used for computers to store information. The binary code is similar to Morse Code, in that it uses tiny bits of information to represent letters and numbers.

    The ‘compression scheme for lossless variable length encoding’ is also used in every other form of technology that requires the compression and transmission of digital data. Some examples are fax machines, computer networks, high-definition televisions, and modems.

    Huffman earned his B.S., M.S., and PhD, each in electrical engineering. He became a professor in 1953 at MIT. Never seeking a patent for his inventions and contributions, he devoted himself to the teaching of his students, stating, “My products are my students.”
