Choosing a notebook computer

Step 1: choose your screen size
Step 2: look for mobile processors and wireless capability
Step 3: decide how much memory and hard drive space you need
Step 4: add the right accessories

Step 1: choose your screen size

Notebook PCs feature LCDs that use active matrix technology (also called Thin Film Transistor, or TFT) to create bright, crisp colors and a fast refresh rate. TFT comes in three formats:
• XGA (Extended Graphics Array): 1024 X 768 resolution (786,000 pixels)
• SXGA (Super Extended Graphics Array): 1280 X 1024 resolution (over 1 million pixels)
• UXGA (Ultra Extended Graphics Array): 1600 X 1200 resolution (nearly 2 million pixels)
The size and quality of the screen is one of the biggest factors in a notebook's price, so carefully consider your needs and balance them against your budget.
If you want the freedom to roam around the house, go down to the local coffee shop, or take an occasional business trip, a notebook with a 15” or 17” screen is the way to go. These make great replacements for desktop PCs, and many feature widescreen aspect ratios, similar to many LCD and plasma TVs. This wider aspect ratio is perfect for watching DVDs and working on multimedia projects. The larger screen will be more comfortable for daily use, but will make your notebook heavier and may drain the battery faster.
Smaller, lighter notebooks are great for frequent travel, or as a companion to your desktop model. Weight will be crucial if you are toting your notebook around campus or through airports every day. Versions with 12" or 13" screens can weigh as little as four or five pounds. The smaller display may not be as easy on the eyes, but your notebook case will be much easier to carry.

Step 2: look for mobile processors and wireless capability Mobile processors such as the Intel® Pentium® M and AMD Sempron™ offer more power in a smaller package as well as longer battery life. Some processors even determine which parts of your PC need the most power and shut down the ones you're not using. These power-saving features are especially helpful when you're on the road and don't have access to an outlet.
Most notebooks also come with built-in wireless capability, perfect for getting online when you’re not at your desk. You'll find public-access hotspots in places like college campuses, coffee shops and airports. You can even create a wireless network in your home and check email in the living room or browse online recipes in the kitchen.

Step 3: decide how much memory and hard drive space you need

Random Access Memory (RAM) is the working memory in your PC. After the processor, RAM is the second biggest factor in overall system speed. As your computer runs programs and works with data, it uses RAM to process the program information. The more memory you have, the faster you will be able to load, print and download your files. To play games or surf the Internet you'll want to start with at least 512MB of RAM. Consider upgrading to 1GB of RAM if you multi-task or work with large files.

The hard drive provides storage for your computer's programs and frequently-used data. Most hard drives today are rated in gigabytes (GB). Not to be confused with RAM, your hard drive is permanent storage for your data. Programs, images, music files and data take up a lot of space on your hard drive, so make sure you start with plenty of room. If you plan to use gaming software or multimedia applications, you'll want the largest hard drive that fits your budget.

About Tablet PC

Tablet PCs are notebook computers with a liquid crystal display (LCD) on which the user writes with a special pen called a stylus. These pens of styli can be wireless devices or attached to the tablet PC via cords or wires. There are two basic types of tablet PCs: traditional and convertible. Traditional products are more rectangular and permit the use of X-Y coordinate logging and optical character recognition (OCR). Convertible products are thin-framed notebook computers that include a foldout keyboard.

Performance specifications for tablet PCs include maximum resolution in lines per inch and maximum sampling rate, the rate at which tablet PCs process user inputs. Accuracy, another important product specification, separates various product lines. Notebook computers that perform standard diagnostic tests can alert users about potential performance problems. Serial interfaces for tablet PCs include universal serial bus (USB), RS232, and RS422. Parallel interfaces include general-purpose interface bus (GPIB), an 8-bit standard. Tablet PCs that use special forms of transistor-transistor logic (TTL) or discrete signals are also available.

Most tablet PCs include special tablet PC software, or standard applications that are compatible with popular operating systems (OS). A basic tablet PC may include a simple word processing application. A more device may include productivity software that provides the user with the ability to schedule tasks or create spreadsheets. Reading a tablet PC comparison or performing an on-line tablet PC review is a good way to learn about product features.

There are many applications for tablet PCs. An industrial tablet PC can be used by plant workers, machine operators, or inspectors in manufacturing environments. A rugged tablet PC can be used by personnel who work outdoors (e.g., forestry, utilities, and construction), or by emergency personnel such as police officers, firefighters and paramedics. In the commercial sector, tablet PCs have become increasingly popular due to increased processor abilities and the development of languages such as Java and Python. A used tablet PC or a refurbished tablet PC is suitable for many applications.

Apple Notebooks

With a little bit of care, you can maximize the battery life (i.e. the time your battery will run before it must be recharged) and lifespan of your notebook's battery. Most importantly, use your Apple notebook in its comfort zone for temperature (See “Keep Your Notebook Comfy”). Don’t leave it locked in a hot trunk during the summer.

Your New NotebookBe sure to fully charge your portable when you plug it in for the first time, and then run Software Update to ensure you have the latest software. Apple periodically releases updates that may improve battery performance.

Standard MaintenanceFor proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month. Need a reminder? Add an event to your desktop’s iCal.

Long Term StorageIf you don’t plan on using your notebook for more than six months, Apple recommends that you remove and store the battery with a 50% charge. If you store a battery when it’s fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life. Be sure to store the ejected battery at the proper temperature. (See “Notebook Temperate Zone.”)

Optimal SettingYou can choose to use your Apple notebook in a way that maximizes its battery life.

• Energy: The Energy Saver control panel offers several settings that determine power levels for your PowerBook. Your portable knows when it’s plugged in, and runs accordingly. When on battery power, it will dim the screen and use other components sparingly. If you change this setting to maximize performance, your battery will drain more quickly.


• Brightness: Dim the screen to the lowest comfortable level to achieve maximum battery life. For instance, when watching a DVD on an airplane, you may not need full brightness if all the lights are off.


• AirPort Wireless: AirPort consumes power, even if you are not using its features to connect to a network. You can turn it off in its control panel to save power.


• Bluetooth Wireless: Likewise, you can turn off Bluetooth to maximize your battery life, as it also consumes power when not in use.


• Applications and peripherals: Disconnect peripherals and quit applications not in use. Eject CDs and DVDs if not currently accessing them.

10. Insurance! If you do a lot of traveling, you may want to invest insome laptop insurance. Laptop theft is a still a big problem and it'sbetter to be safe than sorry.

Notebook (style)

Notebook is a style of writing where people jot down what they have thought or heard at the spur of moment. The contents of a notebook are unorganized, and the number of subjects covered in a notebook are unlimited: a paragraph of autobiography can be followed immediately by one on astronomy or one on history.
Some famous authors are also famous for the notebooks they left. The Italian poet Leopardi kept a notebook, called Zibaldone, from 1817 to 1832. The idea of keeping that, which contains no less than 4,526 pages, was possibly suggested by a priest who fled from the French Revolution and came to live in the poet's hometown. The priest suggested that "every literary man should have a written chaos such as this: notebook containing sottiseries, adrersa, excerpta, pugillares, commentaria... the store-house out of which fine literature of every kind may come, as the sun, moon, and stars issued out of chaos."[1]
There are writers who earned their posthumous fame solely by their notebooks, such as the German scientist and humorous writer Georg Lichtenberg. He called his notebooks "waste book", using the English book-keeping term. He explains the purpose of his "waste book" in his notebook E:
Die Kaufleute haben ihr Waste book (Sudelbuch, Klitterbuch glaube ich im deutschen), darin tragen sie von Tag zu Tag alles ein was sie verkaufen und kaufen, alles durch einander ohne Ordnung, aus diesem wird es in das Journal getragen, wo alles mehr systematisch steht ... Dieses verdient von den Gelehrten nachgeahmt zu werden. Erst ein Buch worin ich alles einschreibe, so wie ich es sehe oder wie es mir meine Gedancken eingeben, alsdann kan dieses wieder in ein anderes getragen werden, wo die Materien mehr abgesondert und geordnet sind.(See on-line source)
The notebooks of scientists, such as those of Michael Faraday and Charles Darwin, can reveal the development of their scientific theories. On the other hand, the notebooks used by scientists for recording their experiments are called lab notebooks.
The notebooks used by artists are usually referred as sketchbooks, which may contain more than sketches. Leonardo da Vinci's notebooks contain his writings on painting, sculpture, architecture, anatomy, mining, inventions and music, as well as his sketches, his grocery lists and the names of people who owed him money.

Laptop

A laptop computer, or simply laptop (also notebook computer or notebook), is a small mobile computer, which usually weighs 2.2-18 pounds (1-6 kilograms), depending on size, materials, and other factors.
While the terms laptop and notebook are often used interchangeably, "laptop" is the older term, introduced in 1983 with the Gavilan SC. "Notebook computer" is a later coinage, which was used to differentiate smaller devices such as those of the NEC UltraLite and Compaq LTE series in 1989, which were, in contrast to previous laptops, the approximate size of an A4 or letter size paper sheet.[1] The terms are imprecise: due to heat and other issues, many laptops are inappropriate for use on one's lap, and most notebooks are not the size of typical letter or A4 paper notebook. Although some older portable computers, such as the Macintosh Portable and certain Zenith TurbosPort models, were sometimes described as "laptops", their size and weight were too great for this category.
As of 2007, most manufacturers use the term "notebook" (or some variant thereof) for what most end-users call a "laptop".
Laptops usually run on a single main battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself. Many computers also have a 3volt cell to run the clock and other processes in the event of a power failure.
As personal computers, laptops are capable of the same tasks as a desktop PC, although they are typically less powerful for the same price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption. Laptops usually have liquid crystal displays and most of them use different memory modules for their random access memory (RAM), for instance, SO-DIMM in lieu of the larger DIMMs. In addition to a built-in keyboard, they may utilize a touchpad (also known as a trackpad) or a pointing stick for input, though an external keyboard or mouse can usually be attached.
Many schools have taken in laptop based programs in which every student receives a laptop for school use only. The operating system is configured (or a third party program is installed) to limit the student's access to perform administrative tasks such as hardware or software installation, or operating system modifications. Students are generally permitted to use these systems to take notes, write papers, and perform other school-related activities.

Computing of computer

Memory (Random Access Memory)

For the formal concept of computation, see computation.
Memory (Random Access Memory)
Look up computing inWiktionary, the free dictionary.
information technology Portal Originally, the word computing was synonymous with counting and calculating, and a science and technology that dealt with the original sense of computing mathematical calculations. "Computing" has come to mean the operation and usage of computing machines, the electrical processes carried out within the computing hardware itself, and the theoretical concepts governing them (computer science).

Computer

The NASA Columbia Supercomputer.

A computer is a machine for manipulating data according to a list of instructions. Computers take numerous physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. [1] Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognize personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as "a computer". However, the most common form of computer in use today is by far the embedded computer. Embedded computers are small, simple devices that are often used to control other devices—for example, they may be found in machines ranging from fighter aircraft to industrial robots, digital cameras, and even children's toys.
A computer in a wristwatch. The ability to store and execute programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks as long as time and storage capacity are not considerations.
