But familiarity will also make strangers: you can skillfully switch set up a computer, using keyboard and mouse operation, and perhaps even the layout of its configuration to understand clearly, but not much to understand the laptop in the design, planning, sales and other processes, those different from other and accustomed to the story behind the things.

Why the notebook power cord is not just a simple line, why the notebook can adapt to different voltages around the world, why the notebook will be preloaded with a lot of expensive software, why the different colors of the notebook may also produce a difference?...... The editor has gathered a few small questions for you to get to know the story behind a different laptop computer.

Why is the notebook power cord not only a wire, but also a global voltage universal?

Many of the appliances we use every day are equipped with a power cord that is just a wire. But for laptops, there's always a huge transformer on the power line. This device undoubtedly increases the overall weight of the laptop, but why not just a single wire like any other electronic device? That's why laptops are designed to fit their mobile and portable designs, allowing users to take it around the globe.

Currently in the global range of the use of the voltage is not consistent, China, the United Kingdom, Australia and other countries and regions of 220 kv, the United States, Canada and other 110 kv, Japan, North Korea, such as 100 kv. Transmitting 220 volts is a little cheaper than 110 volts and a little bit more dangerous. Which transmission system is used is a fairly extensive demonstration in most countries, and once the decision is made, the country will invest a lot of money in the selected system. Therefore, it is unrealistic to expect countries to switch to uniform power supply standards in the near future.

So people often have to travel around the country with laptops and so on, they need to ensure that these appliances can be used under different power supply standards. Transformers in the power cord allow laptops to operate normally under different standards.

The vast majority of refrigerators, washing machines, televisions and other electrical appliances do not need to move across the country, just to adapt to a standard operating on the line. So there is no need to add built-in transformers to reduce the cost of manufacturing electrical appliances.

Notebook pre-installed software small secret

Why is the total amount of software preinstalled by some laptops exceeding its own price?

You buy a new laptop, not only can see the hardware equipment, the boot also see a lot of preinstalled software. In addition to the latest version of the operating system, there may be word processing, spreadsheets, slideshows, e-mails, music, photos and other applications, even virus protection software. Why does the manufacturer have to give so much software for free?

Most computers will have many software preinstalled

Many software users are concerned about product compatibility. For example, experts from different fields work on a project, and if they all use the same word-processing software, the exchange is much simpler. Also, if business executives use the same set of financial software as accountants, the days of payroll and tax filing are much easier.

On the other hand, a lot of programs, such as Microsoft Word documents, want to fully grasp or need a certain amount of time. Then the people who cooked the software, often do not want to learn other similar software, even if the latter from an objective perspective better use.

This means that the benefits of owning and using specific software will increase as the number of users increases. This unusual relationship has created an overwhelming advantage for the most popular program makers and makes it difficult for new programs to penetrate the market.
