HDMI, or high definition multimedia interface, is a type of audio and video interface that is used for the transmission of uncompressed digital streams. Essentially, HDMI can be considered an alternative method to transmitting data streams, rather than making use of conventional methods such as coaxial cabling, VGA, or component video equipment.

What Type of Sources May Be Employed Using HDMI?

Quite a number of devices and sources on the market today will work with the use of HDMI. The Blu-Ray disc player, a relatively new innovation, was created with the use of HDMI specifically in mind. Most personal computers that are sold today are ready for use with HDMI, as are the majority of video game consoles in the stores currently. A set-top box also is usually compatible with HDMI, as are such entertainment options as digital television. Essentially, any type of computer interface today will function with the use of HDMI.

How Does HDMI Work?

HDMI will work with a single cable connection to such devices as televisions or personal computers. In general, HDMI will function fine with any television or PC that is standard, enhanced, or high definition in the video component. However, it is important to note that HDMI does work independently of many of the DTV standards, although use of HDMI will not impact the quality of the digital transmission. Generally, these standards apply to some configurations of MPEG movie clips and files. Since these are compressed, HDMI will simply decompress the data and make it possible to view the clip.

Are All HDMI Versions The Same For All Devices?

No. There is a range of specifications that are employed by HDMI, and a given device will be manufactured to comply with one of those specifications. The most simplistic specification is identified as 1.0. With each succeeding version, the capabilities of the previous version remain intact, but are joined by other capabilities that will allow the version to function with a given device. Because technology is always advancing, HDMI continues to advance as well. However, older versions remain active, as they are often used with devices that require less functionality, and they also continue to be helpful in situations where older systems are still running and are in operation.

Where Did HDMI Come From?

HDMI was created and has been enhanced by the efforts of several prominent names in the computer and electronics industry. Consumers will recognize the names of Philips, Sony, Toshiba, and Silicon Image as just part of the roster of corporations involved in the ongoing enhancement of HDMI.

Misconceptions About Refurbished Cisco Network Hardware

Sat, 07 Feb 2009 01:24:23 +0000

Myths and misconceptions surround the market for refurbished Cisco equipment, creating unnecessary fear, uncertainty and doubt. Many of these misconceptions have been precipitated by OEMs; no doubt because some have admitted they look upon the used Cisco market as their No. 1 competitor.

To set the record straight, it's time to debunk some of the commonly heard myths about refurbished Cisco equipment.

Myth #1 - The Secondary Market = The Gray Market
In reality, the two markets should not be painted with the same brush. In fact, most reputable sellers of refurbished Cisco equipment have more stringent practices in place to detect black market or counterfeit goods than most OEMs and VARs/distributors. Product packaging is not a reliable way to judge authenticity, which is why the best used Cisco marketers conduct extensive tests on all used Cisco equipment resold to prove legitimacy. In addition to setting high standards, top providers in the used Cisco market are working closely with law enforcement to eradicate the counterfeit equipment problem.

Myth #2 - Used Equipment is Abused Equipment
Reputable marketers of used Cisco equipment do not sell their goods "as is." All offerings are fully refurbished to ensure they are as close to original condition and performance as possible. Buyers should only deal with used Cisco equipment sources that have a proven track record for longevity, financial stability and outstanding business practices.

Myth #3 - The Equipment You Need is only Available New
More used Cisco equipment is available than ever before. Top providers in the secondary market maintain extensive inventories of the most popular networking equipment. This means the vast majority of requests can be filled on the spot. If not, these used Cisco providers have extensive contacts, enabling them to fulfill requests within days. In contrast, it often takes weeks or months to secure new equipment from manufacturers.

Myth #4 - Third-Party Components = Inferior Products
A third-party component is not necessarily an inferior replacement. For example, Cisco buys its memory from NEC, Samsung and other "third parties" rather than manufacture those products. The memory does not carry a Cisco logo, even when they resell it, so identical items are available directly from the memory manufacturer. Purchasing accessories like memory directly from the "third party" source may reduce costs as much as 80 percent. A knowledgeable used Cisco market provider helps identify these savings opportunities while ensuring all "third party" components are, in fact, high-quality equipment.

Myth #5 - Used Cisco Equipment Comes With No Warranty
In 2004, NHR introduced the industry's first standard, one-year overnight replacement warranty on every used Cisco equipment purchase. Since then, many other players in the used Cisco market have followed suit, surpassing the warranties offered by many OEMs.

Myth #6 - Technical Support is Not Available
Leading suppliers of used Cisco equipment offer both pre- and post-sale technical support from certified technicians. In most cases, these experts test up to 100 pieces of used Cisco networking gear each day, giving them more real-world experience than even most OEM technicians.

Clearly, it's time to dispel the myths and forge past the FUD about the used Cisco market to view this growing segment as a viable and reliable alternate source of networking equipment.

Types of Computer Hardware

Sun, 01 Feb 2009 03:55:33 +0000

Computer hardware is a physical part of a computer that executes within the hardware. It is unlike computer software or data that can be frequently changed, modified or erased on a computer. Computer hardware is not frequently changed and so is stored in hardware devices such as read only memory (ROM) where it is not readily changed.

Most computer hardware is embedded and so is not visible to normal users. Below are the different types of hardware’s found in a computer.

Motherboard: It is the central or primary circuit board making up a complex electronic system such as a computer. A motherboard is also known as a main board, logic board or system board.

Central processing Unit: A CPU is the main component of a digital computer that interprets instructions and process data in computer programs.

Random Access Memory: A RAM allows the stored data to be accessed in any order. RAM is considered as the main memory of the computer where the working area is used for displaying and manipulating data.

Basic Input Output System: BIOS prepares the software programs to load, execute and control the computer.

Power Supply: Power Supply supplies electrical energy to an output load or group of loads.

Video Display Controller: It converts the logical representation of visual information into a signal that can be used as input for a display medium.

Computer Bus: It is used to transfer data or power between computer components inside a computer or between computers.

CD-ROM drive: It contains data accessible by a computer

Floppy disk: It is a data storage device
Zip Drive: It is a medium capacity removable disk storage system.
Hard Disk: It is a non-volatile data storage system that stores data on a magnetic surface layered unto hard disk platters.

Memory Card Speed

Sat, 24 Jan 2009 19:53:57 +0000

In a few short years since the launch of the first 4Mb flash memory card, the number of flash memory cards available for digital cameras and other devices has exploded with a number of different formats and speeds of memory card. It's no wonder the average person is totally baffled by this plethora of memory cards.

Not only are there different shapes (the format) and sizes such as Secure Digital (SD) Compact Flash, Memory Stick etc, but also different speed ratings.

Memory card speed is the card's performance with regard to how quickly data can be transferred to or from it. The card speed is often stated in 'Times' ratings i.e. 12X, 40X etc (just as the speed of recordable CD's and DVD's is measured), and sometimes more specifically in megabytes per second (Mb/s). By today's measure, sub 20X represents a standard speed, 20X to 40X is mid-high speed and over 40X is high speed. The chart below shows the relationship between the two figures.

8X = 1.2 Mb/sec
12X = 1.8 Mb/sec
20X = 3.0 Mb/sec
25X = 3.8 Mb/sec
30X = 4.5 Mb/sec
40X = 6.0 Mb/sec
60X = 9.0 Mb/sec
66X = 10.0 Mb/sec
80X = 12.0 Mb/sec
90X = 15.0 Mb/sec
133X = 20.0 Mb/sec

Why do we need different or higher speeds cards?
This is mainly due to the advancement of our digital devices, especially digital cameras, camcorders and music devices. As manufacturers develop higher and higher spec devices (i.e. higher resolution cameras and more intense multi-media functions), they are creating increasingly larger amounts information to store pictures, movies, music and so on. This in turn takes longer to record onto the memory card. For example if you have ever used a high megapixel camera with a standard speed card you may have noticed the time lag between pressing the shutter button and being able to take the next picture. This lag or delay, in most cases is caused by a slow write speed, similarly copying your photos to your PC could take time too and is caused by a slow read speed.

So who really needs high-speed memory cards?
Professional photographers and enthusiasts using professional grade cameras such as digital SLR's should use high-speed memory cards of at least 40X speed. If you own a camera with a megapixel rate above three million pixels, you will certainly benefit from a card with a higher speed rating. If you're like most of us using a compact camera under 3 million pixels, you'll get great performance from standard cards with 12X or more.

Those using digital camcorders and devices recording MP3 music or video will also benefit from higher speed cards. It used to be the case where very few people would actually benefit from very high-speed cards, typically only professionals who used expensive, specialized products benefited, but it's fast becoming a requirement on many of the latest PDA's, Cameras, phones and other mobile devices to make use of the extra speed made available by high speed cards.

People using high speed memory cards with equipment that has been on the market a while may not notice any difference in performance, but this has more to do with the limitations of the device than the flash card itself. This is because not only does your memory card have a maximum speed rating, but your camera or mobile phone will also have its own speed rating. When these products are combined, they'll work at the "slowest common denominator" e.g. if you use a 12X flash card in a camera with a designed for a maximum of 8X speed, you'll be transferring data at the slower 8X speed.

You should always check the capacity of your device before splashing out on mega fast cards, but determining the speed compatibility of your device can be tricky. Most manuals just don't tell you what speed of flash card you should use, now that would be far too easy, but they do tell you to buy their brand, which isn't much help! So a general rule of thumb, if your camera is less than three megapixels the speed rating of the flash card doesn't matter much. Most modern cameras have the ability to support far higher speeds than the cards available to purchase today, therefore, if speed is of importance, go for a faster card. Most mobile phones, PDA's and Satellite Navigators are fine with standard speed cards although some newer models will benefit from higher speed cards but not generally over 60X speed.

The internet is a good resource to find out about your device, but in our experience the device retailer and forums are not always the best source of information, you would be better to seek information from the manufacture's website or from dependable review sites.

If you are in any doubt about the card you require or even desire, you can always call us at Mouse2house.co.uk on 0845 257 2088 and we will do our best to guide you in the right direction.

USB Hub whats that?

Sat, 24 Jan 2009 19:50:11 +0000

Since the mid 90's we have seen the birth and growth of a connective technology called Universal Serial Bus (USB). Originally designed to connect computers and telecoms equipment, it has slowly become the primary means of connecting a whole host of other devices and has made significant contributions to today's IT world.

The sheer number of USB products on the market today is just staggering, from mice and keyboards, modems, external hard drives to USB fans, lights and coffee cup warmers! Most external computer related devices today connect to a computer via a USB port. So it's no wonder that before long, most computer users find themselves wondering what to do when the USB ports (sockets) on their computer are all used.

There are two solutions to the problem, constantly plug and unplug connectors when swapping between USB devices, or invest in a simple, low cost device called a USB Hub. A USB Hub is a small unit with two or more USB ports, which plugs into an USB port on your computer, allowing you the freedom to connect more USB devices without disconnecting others. Expanding the number of USB ports of your computer in this way not only saves wear and tear on your USB ports and connectors, but also puts and end to all that clambering around behind your PC! Generally speaking, there are four types of available:

1. Internal USB PCI Card
An internal PCI USB Card needs to be installed by opening up the case of your PC and inserting a card into a vacant PCI slot on the motherboard, this type of USB expansion is not advised unless you are familiar with working with and inside computers. If you have the older USB1.1 and upgrade to USB2.0, your version of Windows will also need to be updated so that your PC can support USB2.0 functionality.

2. USB Hub (Non Powered)
An external non-powered USB Hub is a cheap and simple device that plugs directly into one of your computer's existing USB ports and that's all there is to it. These are usually very compact and so make ideal solutions for mobile users with laptops and for desktop users.

Be aware that some USB devices require a small amount of power through the USB port, usually mechanical devices such as printers, scanners, digital cameras and so on. This type of USB Hub may not be able to supply adequate power to these devices especially if you are using a few USB devices together.

3. Powered USB Hub
An external Powered USB Hub is also compact and plugs directly into one of your computer's existing USB ports, so again there is no need to open up your computer to install it. The only difference is that the Powered Hub comes with a separate power supply that must be plugged into the mains socket, supplying the power to all the USB ports on the hub allowing ANY type of USB devices to function properly.

Most Powered Hubs come with a sensible length of USB cable allowing the Hub itself to be positioned in a more accessible place e.g. on top of your computer or on your desk, making plugging and unplugging USB devices much easier. This makes the Powered Hub the all round best solution for desktop computer users.

4. USB PC Card
If you use a Laptop and are on the move, you have an additional choice to the USB Hub, the USB PC Card also known as the PCMCIA USB Card. This device slots into the PCMCIA slot/port found on the side of a Laptop and instantly provides two extra USB ports without using up any of your existing USB ports on the Laptop.
This is the most popular solution for mobile Laptop users. When buying a suitable external USB Hub, consider the location of your computer's USB ports. If they are located at the back of your computer or in an awkward position, you can make your life so much easier by using a USB Hub that comes with a USB extension cable, or by buying a separate USB extension cable. This allows the USB Hub to be positioned to a more accessible place for plugging and unplugging your USB devices.

Buying a Dell Laptop

Tue, 20 Jan 2009 01:17:52 +0000

One of the most well known brands on the market are Dell laptops. Of course, this comes from a lot of advertising. But their quality goes a long way in explaining why they are so big in the IT world.

Let's take for example the new Dell Inspiron 6000. This is a high powered notebook that features the so-called Sonoma chipset which happens to be the latest Intel processor. Now, this chipset is strictly for mobile computers, so it is specifically designed to make sure your laptop works as optimally as possible. This involves the best in battery power life, the fastest graphics for gaming and multimedia, and wireless connectivity.

As far as wireless technology goes, these Dell laptops pack the latest technology. For example, they offer the optional Bluetooth for you business users out there. Of course then there is the standard 10/100 ethernet card and Wi-Fi access, so you can use your card in wireless hotpsots at home, in your local coffee shop ar at work.

Here are a few other accessories that round out the connectivity of these computers. It has an IEEE 1394 port, a Firewire port, an S-Video port and four USB ports. Now, if that's not enough, the Inspiron 6000 also has a slot for Secure Digital Memory cards.

Now, no matter how many digital cameras, music players, personal digital assistants (PDA's), or cell phones you have, your Dell Inspiron 6000 notebook will have enough access for all of them.

This computer also has a big brain! You can choose from either a 1.30 GHz Intel Celeron processor or the 1.60 GHz Pentium processor. As far as hard drives go, they also come in a selection of ranges from 30 GB to 80 GB. You can also pack the computer with optical drives like a DVD double layer burner or a writeable CD/DVD combo.

What does this mean for the layperson? All these numbers and abbreviations mean only one thing, no matter what you need your computer for, there are Dell laptops out there that are perfect for the task.

I have had nothing but Dell computers in my office as well as my home and I will continue to buy them and recommend them. Not just because they are excellently made computers, but because Dell stands behind their products in price as well
as service.

Just to give you an example of the Dell Service, I purchased a Dell Desktop last year for my office, one of many. This one computer did develop a problem with the DVD drive. I could read DVD's but I couldn't burn one. I called support they responded very quickly and while I was on the phone with them the technician had me run some tests. The DVD unit was found to be defective. The technician offered to send me a new unit by next day air or have a technician come to my office. I chose the latter, and the technician showed up within 24 hours replaced the unit and had me up running. Now for me I couldn't have asked for better or faster service.
