Disk Operating System

The words disk operating system refers to system software used in most computers that provides the abstraction and management of secondary storage devices and the information on them.  For example, you have several files systems meant for organizing data files of all sorts.  Such software is referred to as a disk operating system when the storage devices it manages are made of rotating platters such as hard disks or floppy disks.

In the early days of micro computing, memory space was often limited so the disk operating system was an extension of the operating system.  This component was only loaded if it was needed.  Otherwise, disk access would be limited to low-level operating such as reading and writing disks at the sector level.

What is search engine gateway?

Navino launched its search engine gateway service recently. For most of the Internet surfers, search engine gateway is a pretty new concept compared with meta search engine or multi search engine. Put it in simple, it is a web service, which can let you search the best information from the best content providers in one website.

When we try to find information everyday, most of us might go to Google.com. Yes, it's true. Most of the time, Google works well. But does Google return the best information? I guess you would agree that the search engine's ranking algorithm could only give a good answer, but not the best. Well, you may ask, where can I get the BEST? The best weather information? The best book information? The best price for your favorite mp3 player? The short answer is from the brain, from the hand picked information. Therefore, Navino's editors and their users give out that the best weather website is weather.com, the best book website is amazon.com and the best price information is froogle.

Router - Tracing Your Packets

Few people will really care about the path that your packet takes when sending a message, but if you're one of those high tech egg heads then this article may be of great interest to you.  It can become very addictive so proceed with caution. 

If you're using a Microsoft Windows based operation system, then it's very easy to trace the route that your message has taken.  Not only that, you can see exactly how many routers it took to get your message from point A to point B.  You can do this by using a program that is on your computer called Traceroute.  That is exactly what the program does.  It traces the route a message takes to get to its final destination.

Building A Computer Introduction

If you are reading this article, you are probably wondernig, why and how do you build a computer. Building your own computer is more simple than you think and has many benefits.

Why Build A Computer?
Building a computer has many benefits over buying a premade. First of all, it is generally cheaper if you build your own than buying one. If you shop your components, your DIY(Do it yourself) computer will be cheaper than its premade equivalent. If you build your own computer, it will be faster than one that is premade, because most computer manufacturers use cheap components and try to cut corners to cut down costs. Additionally, your self built computer has more room to upgrade if you so decide to in the future. Prebuilt computers usually only have enough expansion slots for the components that are going to be in the computer. Because of this, your prebuilt computer will become obsolete sooner. Also, building a computer is a satisfying experience and you will learn more about how your computer works.

Blu-Ray set to take the world by storm!

The Blu-ray Disc belongs to a new generation of optical discs capable of staging high density data. Blu-Ray technology is based on a blue-violet coloured laser. The blue laser operates at a wave length of 405 nm, while older technology such as DVDs and CDs are based on red and infrared lasers that works at 650 and 780 nm. Since the wave length is shorter with a blue laser, the new Blu-ray technology makes is possible to store much more information

The advantage with the Blu-ray technology is that the laser beam can be focused much more tightly at the surface of the disc. Tight focus means that a smaller spot will be produced on the surface on the disc, and when the spots become smaller there will naturally be room for more information on each disc. The minimum spot size of any laser depends on a naturally accruing phenomenon called diffraction. The narrow beam of light sent out from a laser will always diverge into a wider beam eventually, due to the natural diffraction of

Cabling your home for computer network - still a requirement?

With proliferation of wireless networking and communication equipment it is oh-so-tempting to cut the cord and save a significant sum of money in the process. But is everything that a regular computer networking user needs can be done using just wireless network? Let’s take a look at some pros and contras:

1.    One important advantage of having a cabled network is the available bandwidth or simply speed. At the present point in time the speed of connection via a simple and inexpensive CAT5E cable can be 1000Mbit/sec, whereas the best that IEEE802.11g (one of the many flavors of Wi-Fi) can offer is only 54Mbit/sec. It may not seem so significant if you think you are only browsing Internet, and the DSL speed available to you is 1.5Mbit/sec. However, if you need to print via your network connection on a remote printer, you should realize that the print jobs, depending on the amount of graphic data in them, can easily reach dozens and even hundreds megabytes. Since 1Byte=8bit one 100MByte print job will take 15 seconds (and in reality this time can be much longer) to transmit via a Wi-Fi wireless connection, and this time shrinks

Different Scanners

Flatbed scanners are a device that gives you the ability to scan a document and then convert the document into a digital format. There are many different flatbed scanner on the market but they all share similar characteristics and close the document and a glass lid and press a button and you can use one or two pages of a document simultaneously scan in few seconds.

The positive side on a flatbed scanner is that they have a better analysis than other types of scanners, which makes a poor quality, because a large amount of equipment placed in a small room. The flatbed scanner is larger than most though, is that they are capable of the perfect picture of a document without having to take to move in any direction.

A disadvantage to the flatbed scanner is that it is larger and much thicker, it is homologous. to invest in these times of CT scans to maximize the wireless options to help you realize your scanner at any time in your office and still get the same results. They are a bit more expensive than other scanners, at least in the case of buying
