The Right One When You Have to Buy The Laptops
Where do I begin
If
you decide to buy a laptop, it makes for computing power to take with him. The
choice can be problematic because of significant technical characteristics to
be taken into consideration in relation to the price.
The first things to consider are:
• Screen Size
• Activities to be carried out with the machine
• scale of expenditure
Screen,activities, and price
The typical size of the diagonal of the screen are 15 or 17
inches around (one inch = 2.54 cm). The fact that the actual figures are 15.4
and 17.3 does not change the conditions of the question.
The vast majority of laptop screens has sold just over 15
inches. A larger screen is useful if you open multiple windows together. The
disadvantages are greater size, weight, power consumption and cost.
What do you with a computer is not just the type of car to
buy. To simplify, we can share the predominant activities in three categories:
• Use the Internet (browsing, e) and management of documents
(text, spreadsheets, and presentations)
• In addition to the above, watching movies, listening to
music easy management of graphics applications;
• Additionally processed audio video, games, technical
design, application development.
The three types of loan portable input range, medium and
high, whose prices rise are allocated accordingly.
Organizing for purchase
A practical method for deciding which computer to buy is to
compare the information obtained from multiple vendors, including availability.
The market, in fact, suggests continuous news and offers, often beneficial, not
long.
Operationally, you can create a table in which for a given
screen size, shows in every line:
• Make and model of the computer
• Processor
• RAM
• OS
• Graphics card
• Hard
• Doors and other devices
• Provider
• Price
After filling the boxes with data from written
documents, it is easier to compare and choose.
Features
Some of the data in the table are fixed and need to buy,
even though they still influence the choice: make and model, name of the
supplier and price. For example you could a supplier because the.
Geographically closest or more reliable than others Those who want to buy
products from a particular brand, then it does, if the information on the
rating plate on the computer less attractive than those offered by other
manufacturers. About the hardware, but the game of the comparison of
"objective" between the different values.
Hardware token
Would be quite difficult in a few lines to explain the
properties of the different components of a computer. To ensure a good
purchase, but is enough to make valid assessments in principle with data on
laptops for sale in the last quarter of 2010.
The processors are manufactured by Intel and AMD. Both
develop advanced technologies in the creation of a number of components by
specific symbols. To get an idea of the "power" of a processor than
others, visit web pages up to date with the results of groups of technical
tests (benchmarks), which they are exposed. You can search the Internet using
keywords such as "CPU benchmark" into a search engine.
With regard to the RAM, which have a lower cost portable 3
GB. Those mid-range have 4, while the most valuable and may have six or eight
GB.
Other features that "price" for the RAM, the speed
of data transmission on the bus of the motherboard (type: 800, 1066 and 1333
MHz) and latency. Not always, but clearly stated in the specifications.
The operating system installed more common in laptops at the
end of 2010, Windows 7Home Premium, 32 or 64 bits. Only some providers, you can
install Linux.
A 32-bit operating system cannot be more than 3.2 GB of RAM,
so it is best to machine with 6/8 GB RAM buy only when installed in the 64-bit
version. The graphics card can be shared memory (in RAM) to save most
of them, between 256 and 512 MB up to 1 GB of dedicated memory.
In less expensive computers, reached the capacity of 320 GB
hard drives. In the mid-range is about 500/640 GB, can achieve while in high
1TB.
Element "limit"
is essential to have a laptop with a Bluetooth port, a FireWire
port, built-in webcam The number of USB ports is enough? The drive for optical
media handles CD and DVD or even Blu-ray (high-end)?
Some laptops come standard drives read and write memory
cards in digital cameras and smartphones are used. Almost everyone has an
RJ-45. For connection to a wired network and Wi-Fi to wireless networks
The significance of the presence or absence of ports and
devices of various kinds, which the user can not be evaluated.
As a final advice for buying a laptop, you should have a
solid carrying case. After a padded accordingly, contain able, documents, pens
and wiring, avoid any shock to the unit and forget about important accessories.
