A notebook, a portable computer is a small computer that can be carried everywhere: at the university, on the street, at the tearoom, on the job and can help you make your daily activities easier and more pleasant.

In the IT field, in order to develop and get the results that we have today of the electronic device known as computer we had the contribution of many inventions, discoveries and prototypes.

In our days, the small and portable computers are world wide spread, by becoming accessible as price to everyone. The trends for miniaturization and low prices is a sign of the progress of the technology in the field. The most spread categories of the portable computers from big to small are:
- laptop,
- notebook,
- netbook,
- Personal Digital Assistant(PDA),
- pocket computers, most unscheduled,
- very simple calculators integrated in a hand wristwatch or in the mobile phone.

The portable computer has small dimensions, like the ones of a diplomatic bag or even smaller, is easy to transport and has the advantage that it can be powered many hour from the battery embedded or from the power adapter set at the AC network.

Another advantage of the portable computers is the fact that it can provide you an Internet connection wireless, with a satisfactory data speed transfer, based on the networks of the mobile phones GSM 1G, GSM 2G, GSM 3G(third generation), and can be accessed from everywere you are.

In order to make the connection to the Internet you need a USB connection and a special stick from the provider.

The companies and the institutions usually use computers and big and very big servers, witch are very fast and usually need to be put in special rooms, secure and conditioned – the computer centers.

Components of an hp laptops…Let’s start with the beginning, first we will talk about laptops, then we will talk about the Hewlett-Packard Company and last but not least we will talk about the components of an hp laptop.

When you say portable in the IT field you immediately think at laptop or notebook, it depends on how you like to call it. The first concept of the laptop from our days was Dynabook made by Alan Kay and developed by Xerox Parc at the beginning of the 70′s. A decade later, in 1981 appears the first commercial laptop called Osborne 1. This laptop had the operating system CP/M and it was much bigger and heavier then the modern laptops.As you can see in the picture Osborne 1 had a minuscule CRT screen.Despite the fact that Osborne 1 had big dimensions, it was heavy and that it didn’t function with batteries it had a huge impact in the industry, being the first computer “that people can carry with them”.

Osborne 1
Another model in the laptop’s evolution was Compaq Portable, made by IBM Personal Computer, started in 1983 tooled up with the MS-DOS operating system, much easier than Osborne 1, but who function also without batteries.

In 1982, Bill Moggridge, a British industrial designer launched GRiD Compass 1101 the first clamshell type laptop with keyboard. In that period it’s cost was estimated between 8.000-10.000 dollars.

In 1983, Epson starts to trade the model HX-20 witch had the fallowing characteristics: rechargeable batteries, keyboard with only 84 keys, a small LCD with 120×32 pixels resolution, with only 4 text lines and maximum 20 characters per line.

Let’s pass to the next subject which is the Hewlett-Packard Company: The Hewlett-Packard Company was created in 1939 by two Stanford graduates William (Bill) Hewlett şi David (Dave) Packard (helped by their university teacher Frederick Terman, considered the mentor) witch started this company in a garage in Palo Alto, California, USA with a investment of 538 USD. They’re first invention that was a financial success was the precision oscillator.

HP has success lines in the production of printers, scans, digital cameras, computers for home use and for small companies and once the merge with the Compaq Company was made the company got more computers.

In 2007, HP had an income of 104 billion dollars, becoming the first US IT company who overcame the 100 billion dollars standard. HP became also the biggest personal computer trader overtaking the Dell opponent.

Now, the HP Company promotes itself not only as being a hardware and software provider, but also a full range of services for design, implementation and support for the information infrastructure.

Over the years HP has improved his products becoming one of the best and known products provider.The laptops have improved also over the years becoming easier, smaller and better.

The HP laptops are made with different characteristics depending on the needs of the users.The standard components of a HP laptop are: the motherboard, central processing unit, hard drive, Random Access Memory and the LCD screen, CD/DVD drive, keyboard, video card, sound card and other mechanisms.

HP provides a large range of laptops and notebooks with the best components and for all needs, for home use or for companies use, equipped with system memory DDR3 or DDR2, with different screen dimensions and resolution, with Intel Core 2 Duo central processing unit, with cameras and microphones integrated.

HP is a world leader in the IT industry and provides electronic products at the highest level for all kind of users.

In 2010 the IT products market is very developed and diversified. We can find a multitude of electronic products that can satisfy all tastes and demands. And when we talk about computers, desktops, laptops, notebooks, iBooks, mini computers we cannot complain.

The electronic devices that make our job easier, the laptop can be found in different prices, shapes, forms, weights, from small to large that satisfy the main characteristic of the laptop meaning the portability. The main laptop categories are:

-tablet
-ultraportable
-light laptops
-mainstream laptops
-desktop computer replacer

We cannot complain either about the brads from the IT market. The most well known international brands are: Acer, Apple, Asus, BenQ, Dell, Fujitsu Siemens, Hewlett-Packard, Lenovo, Samsung, Sony, Toshiba and the list may go on. Undeniably those are the IT titans that rule the electronic market, that provide us the best products and because of that they became financial titans also. Every brand has companies in all big countries of the world so that the every costumer to be able to choose what product he consider best for his needs. In this article I would like to score the difference between Apple notebook and HP notebook.

The Hewlett-Packard notebook

The Hewlett-Packard Company presents a large offer of products. On the Pavilion notebooks made for the end users we can see 4 series: in the “zv” series they embedded the AMD desktop(Athlon and Sempron) CPUs, in the “ze” series they embedded the AMD CPUs for notebooks(Mobile Sempron and Turion), the Intel 4 CPUs Desktop can be found in the “zd” series and the mobility with the Pentium M CPUs is found in the “dv” series.

At the business notebook category our attention is drawn by the Essential notebook and Enterprise notebook. Three series from the Essential notebook class(recognizable by the “nx” code) are made especially for the clients who consider the essential criteria the price performance ratio.

The Enterprise series are made considering the users area and the more simple administration in the big networks. In this category we can find 5 notebooks(“nc” and “nw”) and 2 Tablet PC (“tc”).

The Apple Notebook

It’s surprisingly the way that Apple became in time the most sympathetic alternative of Windows. And if you ever worked with a G4 Powerbook or with an iBook you certainly know why. The Mac OS X operating system has everything under control, without looking or being overloaded. The iBooks are available in two sizes, with 12.1 inch screen size and 14 inch screen size. The much more strong , but also expensive PowerBooks can be found from super portable models of 12.1 inch screen size to the ones of 17 inch screen size and can be used successfully as a substitute for desktop. Often copied, the design of an iBook had became a landmark, but the mobile computers from Apple are convincing regarding their functionality also.

When you have so many offers you are entitled not knowing what to buy. But, in my opinion the decisive argument in the decision process of buying an electronic product is given by the good name of the company that creates the products. Many buyers decide to purchase notebooks, laptops, computers, printers, scans, accessories from HP, because they know that the HP Company, has a respectable history,they offer professional products and services and the products are accessible as price.

The laptop memory or RAM(Random Access Memory) is the vital storing data component for every computer. The laptop memory is also known as the computer main memory.
