Small Business Networking Suggesting Dedicated Servers To Clients

Writen by Joshua Feinberg

PC-based servers and LANs may be relatively mature technologies. However, small businesses need your firm's expertise, more than ever. For these businesses, you'll need to select, configure, customize, secure and maintain the right small business networking tools for their unique needs.

Real Small Business Networking Solutions Begin with Real Servers

How many times have you taken on a new small business client who insists that he or she is perfectly content with their peer-to-peer network? You know the peer-to-peer network is really causing a ton of problems.

Is Microsoft Windows peer-to-peer networking any way to run a small business? Perhaps it is for a two-or-three-person company, but those really tiny offices generally aren't your most profitable client opportunities.

Convincing the Client They Need Small Business Networking

Clients come to you because they need a reliable, yet cost-effective small business networking solution. You know that their data, uptime, and security issues are important, and that there are some corners that aren't worth cutting. Yet many small business networking prospects and clients still believe that they're too small to need a dedicated or "real" server.

Cutting Corners Doesn't Cut It

When you begin talking about a network upgrade, small business clients often dwell on out-of-pocket costs. They often neglect to consider the more substantial soft costs of investing shortsightedly in a small business network.

These include lost employee productivity when imprudent corners are cut, downtime when fault-tolerance is an afterthought, and support costs when difficult-to-support or "dead-end" solutions are selected solely because of their low price tag.

The Bottom Line about Small Business Networking

Often clients don't recognize they have a small business networking problem until it's too late. If you show your prospects and clients how a dedicated server can save them money by avoiding inevitable disasters (i.e. share some of your "before" and "after" client case studies), you'll have a stronger chance of getting prospects and clients to see "the light."

Buying Guide To Graphics Cards Contents

Writen by Andrew Gates

The is a vital performance component of your computer, particularly if you play 3D games, or work with graphics and video content. The graphics card sits in an expansion card slot in your PC and it is specifically designed to process image data and output it to your monitor, enabling you to see it. A graphics card works by calculating how images appear, particularly 3D images, and renders them to the screen. 3D images and video images take a lot of processing capacity, and many graphics processors are complex, require fans to cool them and need direct power supply. The graphics card consists of a graphics processor, a memory chip for graphics operations, and a RAMDAC for display output. It may also include video capture, TV output and SLI and other functions. You can find the graphics card that suits you by comparing specification between brands and vendors on Myshopping.com.au

At Myshopping.com.au you can compare a great range of appliances, and assess them according to their specifications, brands, prices and vendors.

What are your needs?

The first decision you need to make is whether you need a graphics card for handling 3D images or whether you are simply requiring 2D image rendering. For 2D requirements, you need only a low-cost solution. In many cases, an integrated graphics solution will suffice for 2D applications.

However with 3D graphics, the performance of the graphics card will impact directly on the frame rate and image quality of 3D programs and games. The differences between the low and high-end cards can be substantial, both in cost and performance.

Rendering 3D graphics is like lighting a stage, both the geometry of the shapes in question and the lighting of it need to be taken into account. The geometry of an image calculates the parts of an object that can and can't be seen, the position of the eye and its perspective. The lighting is a calculation of the direction of the light sources, their intensities and the respective shadows that occur. The second part to presenting a 3D image is the rendering of colours and textures to the surfaces of the objects, and modifying them according to light and other factors.

Most modern graphics cards include a small microchip called the Graphics Processing Unit (GPU), which are provide the algorithms and memory to process complex images. They reduce the workload of the main CPU, and provide faster processing. Different graphics cards have different capabilities in terms of processing power. They can render and refresh images up to 60 or more times per second, calculate shadows quickly, create image depth by rendering distant objects at low resolution, modify surface textures fluidly and eliminate pixelation.

What Specifications to Consider

Processor clock speed

This impacts on the rendering capability of the GRU. The clock speed itself is not the critical factor. Rather it is the per-clock performance of the graphics processor, which is indicated by the number of pixels it can process per clock cycle.

Memory size

This is the memory capacity that is used exclusively for graphics operations, and can be as much as 512MB. The more demanding your graphics applications are, the better you will be served with more memory on your graphics card.

One thing that can slow down 3D graphics performance is the speed at which the computer delivers information to the graphics processor. A higher bandwidth means a faster data transfer, resulting in faster rendering speeds.

Shader model

DirectX Shader Models allows developers control over the appearance of an image as it is rendered on screen, introducing visual effects like multi-layered shadows, reflection and fog.

Fill rate

This is the speed at an image can be rendered or "painted". This rate is specified in texels per second, the number of 3D pixels that can be painted per second. A texel is a pixel with depth (3D). The fill rate comes from the combined performance of the clock speed of the processor and the number of pixels it can process per clock cycle, and will tell you how quickly an image can be fully rendered on screen.

Vertices/triangles

Graphics chips don't work on curves, rather they process flat surfaces. A curve is created by multiple flat planes arranged to look like a curve. 3D objects are created with multiple triangular surfaces, sometimes hundreds or even thousands, tessellated to represent the curves and angles of the real world. 3D artists are concerned with the number of polygons required to form a shape. There are two different types of specification: vertices per second (I.e., angles the triangles), and triangles per second. To compare one measure with the other, you have to take into account the fact that adjacent triangles share vertices.

Anti-aliasing

A technique used to smooth images by reducing the jagged stepping effect caused by diagonal lines and square pixels. Different levels of anti-aliasing have different effects on performance.

RAMDAC

The Random Access Memory Digital to Analogue Converter takes the image data and converts it to a format that your screen can use. A faster RAMDAC means that the graphics card can support higher output resolutions. Some cards have multiple RAMDACs allowing that card to support multiple displays.

TV-out

Some graphics cards provide the option to connect a television via either a composite (RCA) or S-Video connector.

DVI

Some graphics cards include a connector for DVI monitors, handy because a lot of LCD screens support DVI. DVI offers better image quality than the standard VGA connector.

Dual-head

Dual-head is a term used when two monitors are used side by side, stretching your desktop across both.

SLI (Scalable Link Interface.)

With SLI you can couple two graphics cards in your computer, enabling each card to take half the rendering thereby doubling the performance.

When considering your graphics card, it pays to think about how much you need your computer to process your graphics output. Using a high end graphics card with a high pixels per clock rating, large memory, fast processor and other features means that you can run the latest games efficiently, or work in intensive graphics development.

Different Models

While there are many vendors of graphics cards, there are actually only two major manufacturers of chips for graphics cards. Nearly every graphics card on the market features a chip manufactured by either ATI or Nvidia. Cards using the same graphics chip will perform roughly the same as each other. However, even though they use the same chip, some feature slightly higher clock speeds, as well as manufacturer guaranteed overclocking-an even higher clock speed than that specified. Other factors that will influence your decision should include the amount of memory a card has (128MB, 256MB, 512MB) and its additional features, such as TV-Out and dual-screen support.

How To Choose A Barcode Printer

Writen by Ricky Lim

Barcode Printers nowadays comes in all sorts of shapes and sizes with varying price range. Technically, general purpose laserjet and inkjet printers cannot print barcodes by default. Usually, they require a add-on component or module. An example is Capella Technologies which provides barcode printing functionality to standard HP laserjet printers through an add-on flash card. Such barcode printers are usually limited in the number of symbologies that can be used.

Thermal Barcode printers, on the other hand supports multiple symbologies right out of the box.

There are two ways barcode printers print barcode, the first method is Thermal Transfer and the second method is Direct Thermal. Direct Thermal prints the barcode directly on the label while Thermal Transfer make use of a ribbon and a printhead. The ribbon is heated and the image is etched on by the printhead on a pre-defined area.

Thermal transfer allows you to print barcodes on a wider variety of materials than direct thermal. As such, the type of material you are going to print barcodes on is a crucial factor in determining which barcode printer to purchase.

Larger barcode printers usually have the ability to switch between direct thermal and thermal transfer. One disadvantage of thermal transfer is that the ribbon needs to be changed quite frequently. If you are using the barcode printer in a manufacturing environment, there could be a lot of downtime. A direct thermal printer is faster and is useful particularly where speed is required and you are not printing a lot of barcodes all the time. An example would be in a hospital where each patient warded is given a barcode to identify them.

If you need to print thousand of barcode labels at a time. Look at purchasing one of the thermal printers from symbol or zebra. I found them to be pretty good in terms of speed and functionality. I would advise to get a barcode printer that has a larger print width and a larger print label capacity.

Barcode Printing technology has evolved tremendously over the last few years. Lately, barcode manufacturers have implemented several security features to ensure there is no counterfeit coding. The latest models of barcode printers are capable of printing labels with RFID (Radio Frequency Identification Devices) tags in them. Such security features are mandatory in some highly sensitive industries and help to provide a guarantee of authentication.

7 Questions You Need To Ask Before Buying A Notebook Computer

Writen by Sabir Rizvi

If you are planning to purchase a notebook computer, then there are seven key questions that you will need to ask yourself. Doing this will enable you to arrive at the kind of quality notebook that best suits your purposes and current budget.

1 - How portable, how powerful?

The issue of size and weight will determine how easily you will be able to carry around your notebook computer. After all, one of the reasons why you may have decided to purchase a notebook computer in the first place, is most probably based on the issue of portability. You will need to strike a balance based on your needs and requirements between ultra-portables and desktop replacements. The former offer very small-sized and light weight computers but will often sacrifice a number of items in achieving this. For instance they will tend to get rid of optical drives, among other items that may be important to you. With desktop replacements they will usually tend to be heavy and bulky making them a little difficult to carry around.

2 - What should be the processor speed and type?

The processor speed will contribute heavily to how fast you will be able to accomplish tasks on your notebook computer. If your notebook is meant to be mainly a web browser, with word processing and maybe a DVD player, then any processor that has a speed of 1 GHz or more should work. However if you have in mind a desktop replacement then you will need a high-end processor of 1.6 GHz or higher.

Secondly the type of processor is an important consideration too. Processors based on Centrino technology consume less power and yield improved battery lifetime.

3 - What Screen size, what resolution?

It is important to check the resolution of the screen on the notebook you are purchasing. Everybody would like a larger screen but some large screens have such a high resolution that it is counterproductive and makes the reading of standard fonts difficult. You will also have to remember that the larger the screen the heavier and more difficult to carry your laptop computer will be.

4 - Should the notebook have a convincing optical drive?

In laptops nowadays, the choice of optical drives is important. Laptops have these days been turned into portable DVD players with the DVD-ROM or CD-RW/DVD combo drive. They can even be plugged into a home theater system. The problem is that many ultra-portable laptops quite often lack an internal optical drive to save on space.

5 - Do you require redundant ways to access the Internet?

Ability to connect to the Internet is a key feature. You should be careful to look for systems that include a built-in 56 Kbps modem and Fast Ethernet. If you wish, you can go further and look for a computer with an integrated 802.11 b/g wireless adapter because locations with hotspots for connectivity are rapidly and constantly growing.

6 - How long would you be away from the mains on average?

A portable computer with less than two hours of computing time on a single charge is a big waste. You should look to get a system with at least 3-4 hours of battery life.

7 - What Warranty options should you be looking at?

Because laptops are moved around a lot, they are much more likely to break down. Many people make this mistake with laptops because we hardly follow up on the warranty for PCs. Remember that laptops are different because they take much more abuse on the go. So you should ensure that you get at least a one year warranty from the manufacturer.
