13 Comparisons of Vista vs Tiger

By: Paul Wilson

Competitive and fast are two terms that are applicable to the world of computers. Constantly changing and evolving computer systems bring many advantages to the users and techies alike. The race for supremacy between the yet to be launched Vista (scheduled for 2006) and Mac OSX Tiger began in 2003 with Microsoft's announcements of plans for an integrated desktop search functionality in Windows Vista.

While opinions vary and are really personal choices in many ways, the following sums up the functionalities between Vista and Tiger.

1. Vista has a completely redesigned look and feel; it is aesthetic, functional, and exciting according to industry sources. Mac Tiger on the other hand was always famous for its technology and aesthetics which are clean and clutter free. In fact, many of the visual effects that Vista has like translucent icons, high resolution, and animation effects have been integral to Tiger for more than four years.

2. Vista is yet to resolve problems caused by underlying windows, while Tiger has fine tuned the bleed caused by windows beneath the surface ones.

3. The 128 x 128 pixel icons of Tiger have better rendition and clearer resolution than the 32 x 32 or 64 x 64 pixel icons of Vista. However one will only know whether Vista will have resolution independent vector graphics once the final version comes to the market.

4. Both Vista and Tiger have closely similar desk top search functions. The only immediate difference is that in Tiger the filtering becomes operational only after creation of a Smart Folder or using the shortcut keys. The Virtual Folder of Vista is identical to the Smart Folder of Tiger.

5. Vista has next generation features, where the system has enough inbuilt intelligence that organizes data. This fine tunes any searches that need to be done. In comparison to this, the Tiger has an old fashioned system with no specials.

6. Vista supports meta data processing while with Tiger meta data can be created or edited only by using document processing applications.

7. Vista permits users to visually locate files while Tiger does not. Image previews in Tiger are turned off by default.

8. As far as security is concerned the Tiger is by far superior to Vista. Since the Tiger user base is small the number of hackers and attackers are fewer as compared to Windows.

9. User accounts and log ins are safer in the Tiger system and Microsoft plans to incorporate similar systems in Vista to strengthen security.

10. Vista has new systems similar to Tiger that will enable users to assert parental locks or blocks. Parental controls help limit computer usage by children protecting them from several dangers.

11. Security in Vista includes inbuilt protection against rogue attacks, malware, spyware, adware and so on. In the case of Tiger its security system has remained secure and unbreached. Whether Vista will earn the same distinction will be known only after it comes into use.

12. Both Vista and Tiger have great networking features making both immensely usable both at home and in businesses. The Tiger is simpler while Vista is a bit more complex to use.

13. The hibernation mode works instantly in Tiger and Vista is also trying to match its facilities.

While the above draws tentative comparisons between the two systems a true evaluation can only be made once Vista is released in its completed version and comes into use.

Guide to Buying Hard Drives

Image via Wikipedia

By: Andrew Gates

Apart from being one of the most essential parts of your computer, hard drive storage is constantly updating, in terms of both capacity of disk space and in physical size. When it comes time to upgrade your disk storage, there are a number of factors for you to take into account. Once you've made basic decisions about size, connectivity, speed and data transfer rate, and whether you want an internal drive or external, you can search through Myshopping.com.au to find the most suitable brand, and model, and compare the prices of different vendors.

Hard Drives

How A Hard Drive Works

Your hard drive has a number of magnetized platters connected to a spindle. The spindle spins the platters at a very fast speed while a series of read/write heads scan over them both looking for and writing information. This information is transferred via a cable system, or through a wireless connection to a hard disk controller, which in most systems is built into the motherboard, or in some systems installed as an add-in card. The information that comes from your hard drive through its controller is then made available to the components of your computer. The effectiveness of your hard drive (its performance) depends on how much of its capacity remains unused, how well organised the data is (known as fragmentation) and its data transfer rate, which in turn is dependent on its connection type and the drive's spin rate.

Internal Hard Drives

Most computers from, the most basic home models up to the most powerful servers, have an internally installed hard drive. Technology today ensures that they are all generally fast, reliable, and offer dependable storage ability. Most modern computers have installation slots and cabling to enable you to install additional hard drive. This allows you to increase your storage capacity without giving up your existing hard drive.

Internal Hard Drives

External Hard Drives

These drives are essentially the same drives as ones installed inside computers, but cased inside a protective, portable case. This is a good solution for people who work remotely and need to transport large amounts of data. If an external hard drive is your choice, make sure your computer is compatible with the interface that the hard drive uses. An add-in card, such as a FireWire card can help to increase your computer's capabilities. You can compare different brands of external hard drives simply at Myshopping.com.au and search on the connection type, or other specifications.

External Hard drives

Laptop Hard Drives

There have been many advances in miniaturization of hardware components for laptop computing, and hard drive technology is not left out of this loop. Laptop hard drives function in exactly the same way as internal hard drives on other computers, only they are designed to provide maximum storage and efficiency in the smallest possible package. For added flexibility, some laptop computers come with removable hard drives that can be easily installed and removed. However, before you buy a hard drive for your portable computer, check that the hard drive's specifications will meet the standards of your computer, as many laptop hard drives are proprietary, and are not compatible with other brands and models.

Laptop Hard Drives

Size

Your hard drive stores your operating system, its programs (games and applications), your working data, and your digital music and movies. Most new computer purchases have a minimum of 80 GB of hard disk space; many have considerably more. Hard drive space is one of those things, once you have it, you'll find ways to fill it soon enough. There is no real rule of thumb, but consider the cost per gigabyte of storage as a way to guide your purchase. If you work with large files, such as music, video and graphics, it pays to have a big storage space for your work. It may pay you to have two hard drives, one that houses all your programs and applications, and another for storing your work and projects.

You may want to compare the price of say a 160GB drive against two separate 80 GB drives. If one drive fails all is not lost. Today's hard drives however, are fairly robust pieces of equipment and providing they are not abuse, will serve you well for a long period of time.

up to 32 GB Hard Drives

32-64 GB Hard Drives

64-100 GB Hard Drives

100 GB and more Hard Drives

Interface

One key distinguishing factor between hard drives is the way in which they connect to your computer. There are a number of basic types of connection schemes used with hard drives. Each connection type has a range of differences in performance.

IDE (INTEGRATED DRIVE ELECTRONICS)

This is by the most common connection methods. Because the hard drive controller is on the drive itself rather than on the motherboard, it helps to keep costs down. There different IDE standards available. Mostly, you will want to purchase the fastest possible standard that your computer can support. Most computers will support a standard that is faster than what the computer currently supports, so you can buy a faster drive, and update your computer at a later time. The different IDE standards, in order from most basic to fastest, are:

ATA (Basic). Supports up to two hard drives and features a 16-bit interface, handling transfer speeds up to 8.3 MB per second.

ATA-2 or EIDE (Enhanced IDE). Supports transfer speeds up to 13.3 MB per second.

ATA-3. A minor upgrade to ATA-2 and offers transfer speeds up to 16.6 MB per second.

Ultra-ATA (Ultra-DMA, ATA-33 or DMA-33). Dramatic speed improvements, with transfer rates up to 33 MB per second.

ATA-66. A version of ATA that doubles transfer rates up to 66 MB per second.

ATA-100. An upgrade to the ATA standard supporting transfer rates up to 100 MB per second.

ATA-133. Found mostly in AMD-based systems (not supported by Intel), with transfer rates up to 133 MB per second.

IDE / EIDE Hard Drives

Serial ATA Hard Drives

Ultra DMA 100 Hard Drives

SCSI (SMALL COMPUTER SYSTEM INTERFACE)

This is the hard drive interface standard used by many high-end PCs, networks and servers, and Apple Macintosh computers, except for the earliest Macs and the newer iMacs. While some systems support SCSI controllers on their motherboards, most feature a SCSI controller add-in card. SCSI drives are usually faster and more reliable, and the SCSI interface supports the connection of many more drives than IDE. While SCSI drives come in many different standards, many of them are not compatible with one another. So it's important be know that your computer supports the drive you plan to install. The different SCSI connections are:

SCSI-1. A basic connection using a 25-pin connector, supporting transfer rates up to 4 MB per second.

SCSI-2. Uses a 50-pin connector and supports multiple devices with a transfer rate of 4MB per second.

Wide SCSI. These drives have a wider cable and a 68-pin connection that supports 16-bit data transfers.

Fast SCSI. Uses an 8-bit bus but transfers data at 10 MB Per second.

Fast Wide SCSI. Doubles both the bus (16-bit) and the data transfer rate (20 MB per second).

Ultra SCSI or Ultra Wide SCSI. Uses an 8-bit bus and transfers data at 20 MB per second.

SCSI-3. Features a 16-bit bus and transfers data at 40 MB per second.

Ultra2 SCSI. Uses an 8-bit bus and transfer data at a rate of 40 MB per second.

Wide Ultra2 SCSI. Uses a 16-bit bus and supports data transfer rates of 80 MB per second.

SCSI Hard Drives

Ultra320 SCSI Hard Drives

FIREWIRE (IEEE 1394)

The FireWire standard is becoming popular in portable hard drives because it can be connected and removed without having to reboot the computer. It supports data transfer rates of 50 MB per second, which means it is ideal for video, audio and multimedia applications. FireWire requires a dedicated add-in card and the hard drives in use require an external power source, but the interface can support up to 63 devices simultaneously.

FireWire Hard Drives

USB 1.1 (UNIVERSAL SERIAL BUS)

Pretty much all computers today include USB ports on their motherboards. (On older model, you can install an add-in card.) USB controllers can be used to connect external hard drives, and can support as many as 127 devices simultaneously either through USB port hubs or linked in a daisy chain fashion. USB controllers do delivery power to devices connected to them, but many hard drives still use an external power source. USB is limited by its data transfer speed, the maximum rate being about at 1.5 MB per second.

USB Hard Drives

USB 2.0 (HI-SPEED USB)

A more recently introduced and far better connection standard that offers backward compatibility and data transfer rates of up to 60 MB per second. USB 1.1 system can use a USB 2.0 device; it will need a USB 2.0 controller card to achieve the higher transfer rates.

USB 2.0 Hard Drives

FIBRE CHANNEL

Fibre Cabling is mainly used for high-bandwidth network servers and workstations, providing very fast data transfer rates (up to 106MB per second), and connection at long cabled distances, although it is expensive and you need to install a special interface card.

Spin rate

Data transfer rate is crucial to how well your computer performs for you. Apart from the connection types above, the performance of your hard drive depends on its spin rate, measured in RPM. Higher RPM generally means faster data transfer rate. The lowest spin speed that is acceptable in computing today is 5400 RPM. The common standard at present is 7200 RPM. But higher speeds are available in SCSI drives, and it is one area of computer system technology that is constantly being developed.

3600 RPM Hard Drives

4200 RPM Hard Drives

5400 RPM Hard Drives

7200 RPM Hard Drives

10000 RPM Hard Drives

15000 RPM Hard Drives

A larger capacity hard drive will not necessarily make your system function any faster unless you are low on available disk space with your existing drive. But a drive with Ultra ATA/100 or ATA/133 and a 7200 RPM spin rate will pretty much guarantee an improved hard drive performance.

Other considerations

CACHE

Cache (pronounces 'cash') is additional temporary memory that acts as a buffer between the system and the drive. Frequently accessed data is stored in the cache for quick access. Cache sizes vary from 512 KB up to 16 MB on some SCSI drives. The larger cache you have on your drive, the faster your drive will transfer data. If you are working with large files, such as video, images and audio files, it pays to have the largest cache you can get (8MB or more).

SEEK TIME

The data on your disk is stored in tracks and sectors and when you instruct your hard drive controller to retrieve some data, it goes looking. The seek time is a measure of how long it takes the hard drive to find a specific track on a disk. Seek times can vary slightly from disk to disk and a drive with a faster seek time will always perform better.

INTERNAL AND EXTERNAL TRANSFER RATES

These two rates tell how fast a drive actually reads the data and passes it along to the system. Internal Transfer Rate refers to the time it takes for a drives heads to read data from the platter and pass it to the drive's cache. The External Transfer Rate (sometimes called the Transfer Rate or the Burst Transfer Rate) is a measure of the time it takes to send the data from the cache all the way to the computer's memory. Naturally faster transfer rates provide better performance.

S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology)

This is a nice built-in feature in some hard drives that can help alert you to a potential hardware problem. Your computer's BIOS must support this in order for the SMART function it to work, however the drive itself will still work in a system without it.

Buying and installing a hard drive has some technical aspects that you need to take into account. Use Myshopping.com.au to compare different hard drive makes and specifications to find the drive that will work best for your needs and computer. You can compare prices and service offers from different vendors.

Ipod Most Popular Mp3 Mp4 player

Image via Wikipedia

By: Roberto Sedycia
This is an mp3 / mp4 player that music lovers acknowledge the most in the modern time. US-based Apple, one among the largest producers of computers, notebooks and computer hardware and software, introduced iPod in 2001 with a single model for the international music market. Apple kept on introducing new iPods for each generation. The latest one is the iPod 5G. Apple also came up with two different variants: the iPod Shuffle (without digital display), the iPod Nano (the smaller version of iPod). Recently, Apple came up with the new-generation of iPod, the iPhone that integrates the conventional MP3 and video player with an internet ready mobile phone.

This article compares each iPod by its special features. One of the most popular model is the iPod 5G that comes with 30 or 80 GB storage capacity. It is not just an mp3 / mp4 player, you can store, view and share complete music videos, movies, podcasts, play games, share photos, playback music and videos, connect to a video output device, and much more. It can play your favorite music for up to 20 hours as this iPod boasts of higher battery life.

The iPod Nano has many of the same features as the full-size iPod, but with much lesser storage capacity. It comes in 2 GB, 4 GB and 8 GB models. It has up to 24 hours of battery life and is comparatively lighter and smaller. It also suffers from some limitations; the iPod Nano doesn't support voice recording and media storage via third-party peripherals. iPod Nano is a great mp3 player for people who would just like to listen to audio files.

Apple's most-pocket friendly iPod is iPod Shuffle. It offers a host of advantages: it's affordable for everyone; its sound quality is as good as that of any other iPod; it has flash memory rather than a hard drive; and it's really portable. However, the disadvantage is that it doesn't include a screen for steering up to specific songs. It has a limited storage capacity, 512 MB to maximum 1 GB. So it's good for those who want to be in fashion, yet can compromise on memory space. But the size of this mp3 player is so small that you can easily clip it to your clothes.

With digital music being in-vogue, many portable jukeboxes hit the market, since Apple kick-started the music revolution of our time. Other portable MP3 and MP4 players, besides iPod, are available in the entertainment world of mp3 / mp4 players. There are many Chinese, Korean and Japanese brands manufacturing low cost players in bulk. These are much cheaper, but have their own set of advantages and disadvantages. The fact remains that iPods are the most popular among all, and hold the biggest share of this market. There are enough iPod users in the market and a lot of new things are getting developed around iPods.

Some people just can't do without their iPods, from jogging time to bed time. It sticks to their ears. Obviously, the battery drains out of the device. The latest buzz is that Andrew Schneider, a student from New York University, is exploring a solar-powered bikini that can charge iPods. Yes, it is true! The bikini will soak up the sun rays thru photovoltaic film strips. That means, while the iPod user is getting a sun tan, his mp3 / mp4 player is also getting a charge of 6.5 volts of solar power.

iPod has become a very desired mp3 / mp4 player around the world. iPod player just seems to be ahead of its competitors. Not just by delivering good quality products, but also in providing new solutions for eager electronic consumers. Let's just wait what will be next in the iPod revolution.
