Take Note

Notebook computers, commonly referred to as notebooks, are personal computers that are very light. To understand the notebooks concept you need to understand what personal computers are.

A personal computer is relatively small and inexpensive, compared with the computers of large businesses and organizations that act as servers or run computer operations on a grand scale. Personal computers are made for the use of individuals or small business entrepreneurs. Many personal computers are used in home offices nowadays. Many rely on notebooks as their only or their additional choice.

Personal computers can be purchased for a few hundred dollars or several thousand. Notebooks are somewhat higher in cost. All personal computers are based on the technology of microprocessing that enables the computer and notebook manufacturer to install a complete CPU on one computer chip. A business can use a personal computer, and sometimes a notebook, for accounting tasks, word processing, desktop publishing projects, database management, and spreadsheets. Notebooks or personal use PCs are often used for gaming, music and even movies.

Before notebooks the first personal computers showed up towards the end of the 1970’s. The Apple II, launched in 1977, was one of the first personal computers. It became one of the most popular as well. The introduction of new operating systems and new computer PC models seemed a nearly daily routing during the end of the 1970s and into the early 1980’s. The IBM PC was introduced in 1981, taking over first place status among personal computers. At this point, with the exception of Apple, many personal computer brands and manufacturers fell by the wayside thanks to IBM’s onslaught.

The result, still prior to notebooks, was the production of IBM clones by other manufacturers. These clones, with nearly the same internal components as the real IBMs, were much less expensive. They used the same microprocessors and could run identical software. While IBM, thanks to price and innovations that weren’t accepted such as the OS/2 operating system, is no longer the preferred PC brand, its notebooks are widely acclaimed.

Now personal computers are divided into two types – PCs and Apples. Personal computers, whether desktops, notebooks or laptops are designed as single user machines and run on microprocessors. They can be linked into a network, however, to use several of them together. The power of personal computers varies considerably from one to another.

Notebooks typically weigh considerably less than PCs – fewer than six pounds. They are typically so small that they can easily fit into their own carrying case or briefcase. Notebooks use a flat panel technology to have a display screen instead of the monitor that runs as a separate piece of hardware on a PC. Notebook display screens have considerable variation in display screen quality. The resolution can be either VGA (video graphics array) or SVGA (super VGA.) Designed by IBM, VGA systems provide a text mode resolution of 720×400 pixels, and a graphics mode of either 16 colors (640×480) or 256 colors (320×200.) The latter is the most common. SVGA is a standard for graphics, with greater resolution than the original VGA. SVGA supports resolution of 800×600, equal to 480,000 pixels.

The computer power of notebooks is actually just about equivalent to that of personal computers. Notebooks have the same capacity for memory, the same CPUs, and the same disk drives as PCs. The small package this power comes in is what makes them more costly than the PCs

One of the most popular aspects of notebooks – what makes them preferred to PCs for many road warriors, is their portability. Notebooks have battery packs installed so they can run without electricity for 2-4 hours before having to be recharged.

Recycling is one of the best ways in which to have a positive impact upon the world in which we live in. Recycling is highly beneficial for the natural environment and human beings. The amount of the rubbish we create and dump into the environment is rapidly increasing everyday, which is having a horrendous effect on the environment, resulting in global warming and the increase in temperature rise.

The reasons why we are creating more waste are due to; increase in wealth, therefore we have more money to buy products, resulting in more waste. Increase in population means, there are more people creating waste. New packaging and technological products are being developed, much of these products contain materials that are not biodegradable.

Recycling is incredibly important as waste has an extremely negative blow upon the ecosystem. Harmful chemicals and greenhouse gasses are released from rubbish in landfill sites. Recycling helps to reduce the pollution caused by waste. Habitat destruction and global warming are some the affects caused by deforestation. Recycling reduces the need for raw materials so that the rainforests can be preserved.

The production of computer parts involves numerous chemicals which are highly dangerous to our Health and surroundings. The Information Technology production industry has enormous carbon imprints; however the carbon imprints can be reduced through recycling of computer components.

In order to produce computer parts the IT industry uses raw dwindling resources and materials which are already relatively scarce. It is a well known fact that major companies only keep IT equipment for around 3 years and then dispose of it. Most of the IT equipment is in good condition and can be reused and deployed in the use of charities, homes, schools etc.

Recycling can help in the deployment of old computers, computer components and other computer related equipment, recycling redundant and damaged computers can be turned into component metals which can then go towards building new computer or fixing damaged machines.

Most of the environmental concerns which lie with inappropriate disposal of computers are the monitor. Each colour monitor contains on an average of 4 to 5 pounds of lead. Other chemicals found in computers are mercury, cadmium a known carcinogen and Hexavalent Chromium which is known to cause high blood pressure, iron-poor blood, liver disease, and nerve and brain damage in animals.

Organisations such as Oxfam have set up schemes where other charities and schools in the third world can benefit from old disposed computers. Oxfam collect old computers in order to raise money to help those in need. By disposing of computers in this way, you can help the environment and decrease the population levels. Also at the same time companies can feel good about the way they have disposed computers, knowing that they are helping others.

It is very important to recycle computers, due to high number of computers being disposed of incorrectly or just stored away, is increasing the risk of polluting the environment with unfriendly toxins and excess waste.

Basically any part / component of a computer can be recycled, the keyboard, mouse, printer and monitor. The steel cases can be sold on for scrap metals, as can the chassis of the computer, floppy drive chassis, hard drive cases and drive platters. Heat sinks have to be separated out during the recycling process due to their high aluminium alloy content and these are recycled separately and for less money per kilo nonetheless still worth a cash value.

Just by correctly disposing products can help the environment greatly. By doing this you are also doing your bit to help fight against global warming, habitat destruction and deforestation. All things which are harmful to us and the future generations that have to live on this planet. Due to vast amount of computer waste, computers could become more expensive, due to European laws may force makers to recycle old machines and Computer Hardware in order to help the environment.

Computer experts have warmed when the new laws are put into force overall computer prices may levitate to anything between $50 to $100. This may force companies into leasing computers to reduce their CPA, and bring down cost in general.

Overall disposing of computers correctly by recycling parts and components could result in a better cleaner less toxic environment. Cleaner environment means less global warming, habitat destruction and deforestation. Also reducing the amount of raw materials needed in order to produce these machines. It is therefore highly important to dispose of the computer in the right place. In many countries dumping of electronic equipment in many areas is banned due to highly toxic chemicals in some components.

The Personal Data Assistant (PDA) has won rapid acceptance among university students and executives who are constantly on the move because of its ability to package a lot of different data requirements into a palm sized device. The PDA is designed to make a busy life easier by providing sensible connections to all the information you need, have it at your fingertips when you need it, and transport it to other systems. Once ‘organised’ with your PDA, you will have all of your contact phone numbers, be collecting your emails, process your business orders, display your photographs and relax to your mp3 library. Many PDAs also act as a digital recorder and have windows based compatibility for word processing and spreadsheet financial calculations.

PDAs At the simplest end of the market, a PDA can help you manage your daily to-do lists, keep track of your diary and record your memos. But it’s important for people moving into using a PDA to understand that it is a tool that is most beneficial to an already organised mind: it won’t actually do the organising for you. But if you find you need to view and manage documents on the go, keep track of your appointments and have instant access to your name and address book, then the basic functions of a PDA will probably enhance your productivity. And of course the added bonuses of listening to your mp3s, watching short video clips, reading ebooks and being able to rehearse and review your presentations can only help.

PDAs with the Windows Pocket PC operating system and gutsy memory are compatible with your normal windows and office environments. Screen size and image resolution can be critical if you intend to use the device for reading books and managing text-heavy documents. While sales of PDAs have steadily declined over the past two years, losing to smartphone technology, the main manufacturers have advanced the usability of PDA devices with faster processors, increases in memory and multimedia capability. In many situations, smartphones have been able to replace many functions of the PDA, combining data management with mobile phone technology. But if you want to work with spreadsheets and web pages on your PDA, smartphones are at a disadvantage from smaller screen sizes and data storage capability and sometimes cost, but they obviate the need to carry two devices.

What to look for

There’s a hand-held PDA device to suit practically every budget and need. You need to consider just how much data you want to carry with you and how connected you want to be. Obviously more memory, faster processor and bigger screen attract higher price tags. You can compare brands, models and prices by searching Myshopping.com.au using the following specifications to guide you.

A budget basic unit might offer a processor speed of 16 MHz, 8MB of memory and at 2.5 inch (diagonal) screen. At the high end, you can get a 4GB micro hard drive, WiFi and Bluetooth connectivity, 400 MHz processor, 256MB memory, with expansion slots, 4 inch (diagonal) LCD screen with 65,000 colours and 640×480 display resolution, GPS functionality, MP3 player, digital camera and instant messaging. In the middle of the range you will find devices with 64MB of memory, a 200 MHz processor, 3 inch screen and built-in microphone or audio input jack. Bear in mind that all of these specifications and functionalities change continuously, and devices are upgraded with new features over very short spaces of time.

Apart from processor speed, memory and screen size, some of the critical specifications that you can use for cost and brand comparisons include:

Data input – While some models have a full QWERTY keyboard built-in, you may want to consider adding a fold-up full-size external keyboard. Entering lots of text with the small built-in keypads or using the handwriting software can be frustrating.

Audio input – A built-in microphone or microphone jack is needed for recording voice memos and meeting notes and store audio files.

Music playback – MP3 audio file playback can sometimes need additional software.

GPS – While there are a number of purpose-built hand-held devices for industrial applications, your PDA’s GPS capability may not be suitable for rugged outdoor activities.

Communication – Look for integrated Bluetooth 1.1 and a built-in 802.11b Wi-Fi adapter

Smartphone – Combines the functions of a mobile phone with a data management device in a single unit. Phone capability requires a separately purchased service contract

Audio Output – A headphone jack is essential for listening to your audio files

Cradle/Charger – This device allows for easy connection and synchronization with your PC while simultaneously recharging your battery. Consider buying an additional cradle for the office for maximum convenience. Some PDAs include a cable or a special cradle that provides an interface with your desktop computer to synchronize data.

Battery life – Each device will have its own battery-life characteristics. Battery recharge life is also dependant upon the data you are processing. You can use manufacturer’s specifications as a guide to compare between brands and models, but these specifications are laboratory measurements and may not reflect your actual use.

Bluetooth – This wireless technology lets you to exchange data with other handheld devices or any other Bluetooth enabled device such as a cell phone, fax machine, personal computer, laptop computer, headset or printer. The Bluetooth feature will allow you to add an external keyboard.

Digital camera – PDA cameras usually capture low resolution images (around 1.2 megapixels), which are perfect for emailing but not ideal for printing.

GPS – Global positioning system allows you to navigate from any point on or near the surface of the earth.

Music/Audio – The MP3 playback quality will depend on the bit rate of the audio file and the quality of the built-in speaker. The audio quality is often better when played back through a quality headset.

PDA Screen – PDA screen sizes are measured in inches diagonally and are available from 2.6 inches up to 5 inches on the very high-end. Larger, brighter screens require more power to operate therefore increase battery consumption.

Processor speed – refers to the speed in which a PDA coordinates its internal functions. Processor speeds are measured in MHz (megahertz) and range between 4 MHz and 624 MHz. Although these specifications can change rapidly as technology develops, it is recommended to have a processor speed of at least 16 MHz for general day-to-day functions.

Video capture – Video playback often requires an additional expansion card and a third-party software download, and higher memory capability.

Web Browser – Used with a Wi-Fi connection, lets you browse the internet as you would from a desktop computer.

Wi-Fi – Integrated 802.11b WLAN (wireless local area network), enables you to connect to the internet in any hot spot. Enabling the Wi-Fi features tends to consume battery life quickly.

In summary

You may like to consider whether you are a novice (that is, new to PDA technology), an entrepreneur or a technophile, and make your search based on your level of understanding of the technology involved. As a novice, you will be searching for a basic unit, as a technophile you will be looking for all the bells and whistles. An entrepreneur will be searching for the most adaptable capabilities. The following might assist.

Choose amongst functionalities. Consider you need for mp3 players, or video players, or web browsing. Doubling the functionality of your PDA may reduce the need to have to carry another device around in order to enjoy the benefits offered.

How much internet access do you need? Bluetooth connectivity can give you mobile phone enabled internet access, Wife can give you access from hot spots, and simple cable connection to your desktop computer can let you read your emails on the road.

Go for maximum memory for money. Memory determines how much data your PDA can process and store, and its ability to handle applications. Memory can be boosted in many devices using expansion slots and flash memory cards.

Search Myshopping.com.au to compare models and brands, and vendors and prices.
