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 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, the best book website is 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

Should I Create a Website?

People always want to follow the latest thing, be it in fashion, sports, that kind of thing. Websites have become a necessity to almost everyone. Companies, businesses, individuals, even young adults have created personal websites with their respective purposes, be it for profit, or for entertainment.

What one must consider, however, before creating a website, are the factors in which must be put to thought before doing so, such as the cost, maintenance, use, web host and so forth.

Firstly, associating with the cost, we must always try to find an affordable host, not spending too much, nor too little. A cheap host does not exactly symbolize a credible reliability rating, but we must always look for value for money deals. Also, regarding the efficiency and server/web host reliability, there are many cases of web hosts not providing the service they had assured other people, some had even shut down and were nowhere to be seen. Keep this note in mind, as if you would like a long-lasting website, this would be the first


“Cartridge” refers to a detachable sub-unit that is held within its own container.  They were popularized by early home computers like Commodore 64 and early TV games systems. The advantage of cartridges lies in the fact that they facilitate quick loading of software from one media format to another. It also helps maintain the software in a sturdy and damage-resistant form.

Throughout the 80s and the 90s, all home video game systems were cartridge-based. As technological advancements in the late 90s ushered in CD technology as a cheaper alternative for data storage, hardware companies shifted from cartridges to CD-based game systems. This was on account of the lower costs and larger storage space provided by a CD-ROM.

Are Inkjet Printers the right choice?

Inkjet Printers are not only getting better but they also becoming less expensive with time. A branded inkjet cartridge can cost you $30 or more and if your printer uses a multi-color ink cartridge system ink costs could easily $1000 to replace all inkjet cartridges for your entire inkjet printer.

The growing business of inkjet printers has brought about additional benefits to them. Manufacturers have built their business around the supplies rather than the printer itself. They have made the inkjet printers an inexpensive commodity sometimes selling them at lower cost or may be even less thereby making long term profits from inkjet printers.

Domain Names and Search Engine Ranking

Does the length of your website's domain name registration affect search engine optimization and results?

Should you renew your domain name for a long period of time? And if so, how long is long enough? If you want to stay ahead of your competition, then you might consider looking at the length of time your competitors have registered their domain names. If your competitors have generally renewed their domain names for one or two years, you might consider registering your domain name for 5 or 10 years. While putting off your domain name's expiration date might help your search engine rankings, keep in mind that this may be only a small victory when it comes to search engine rankings.

Its good business sense to register a domain for at least 10 years. You don’t want to deal with the process   annual process of renewing them every year. It’s best to obtain the domain names that you want to keep for a while and renew then on a 5 to 10 year plan.

Be Picky About Computer Keyboards

If there is anything I have learned in the past ten years of being an editor that is using my computer all day, it is that it is good and right to be absolutely picky when it comes to choosing computer keyboards. If this seems like an insignificant choice to you, then it is clear that you, unlike me, do not spend the majority of your days typing on a computer.

If you did, you would quickly realize what a difference computer keyboards can make to a typing experience. It took me a couple of years to realize that there were actuallly a lot of options when it comes to computer keyboards and that I didn't have to be satisfied with a computer keyboard that didn't fit my hands.
