Topic - About laptop computers (NOTEBOOK).

 SUBJECT.             
                                
today we will talk about
laptop computers or about
so-called laptops (from
English word notebook -
notepad).                       
   The first computers of this kind
were introduced to the market
by Toshiba in 1986.
The main idea of this product is
create completely MS-DOS -
compatible computer
size so that it can be
easy to carry and also
use on the road.    B
currently technical
laptop specs and so on
called desktop
computers, or desktops,
almost equal.  This is due to
the following points:           
                                
           - Processor.         
                                
   Modern processors
workon low power
(about 3B) and consume
relatively little energy.  This
gives an opportunity after
new release announcements
processor almost simultaneously
create both desktops, and
laptops running on this
processor.                     
                                
    - Expansion devices.    
                                
   In 1992 the same company
Toshiba standard was proposed
to expansion and communication devices
with the outside world for laptops.
Creation of this standard
put an end to development
called portable
computers that tried
combine portability and
using standard AT -
compatible devices.          
                                
           - Display.           
                                
   Currently active
matrices have size, brightness and
clarity that is comparable to
desktop displays. At the same time
liquid crystal matrices
laptops do not give harmful
healthradiation, therefore
there is no longer a need for
using a protective screen.
All these factors led to
that laptop bought today
becomes morally obsolete as well
soon, as well as desktop.  Others
in other words, laptops have
almost equal opportunities in
using new
software and
fulfillment of withdrawal requirements
information on the screen. If earlier
laptop computers
have already lost this competition
at the start, now their positions
equalized.                       
             - Prices.            
                                
   Prices for notebooks are approximately
one and a half to two times higher than prices for
desktops.   However, comparing
prices, it should be understood that
what can be compared and what cannot. 
   So a laptop from IBM is needed
compare with desktop
computer from the same company, and not with
some little-known
assembly. Note that at a price of
1.5-2 times higher user
gets a car with exactly
the same computing
characteristics and qualitydisplay, like a desktop one
computer.                     
   But we should not forget that
laptop remains important
advantage, what is it for,
in fact, it was conceived - this
ability to work on the road without
mains power, possibility
connections with the outside world or with
central computer from any
points.   Already today about this
people should think about it
needing two desks
computer (at work and at home):
representatives of the middle and
big business, people
creative professions (writers and
journalists) whose work is related to
frequent moves...           
   (Now, let me
a little lyrical
retreat.                    
   As a typewriter
you can use the same one at home
ZX-SPECTRUM, with output
information to the printer. He's nothing
no worse than the vaunted IBMa, if not
take quality into account
prints and wider
opportunities provided
text editors for
working with texts.              
   An important factor
is also the price, which is lower
thanIBMob tens of times,
she's the one who forces
user stop his
selection on ZX-SPECTRUM.   This one
the computer is very easy to use
management and does not require special
programming knowledge and experience
working on a computer, except
there is a huge amount of this
quantity is relatively cheap
literature describing in detail
work and application are very
a large number of programs and
internal features of this
computer.)                    
 ...But let's not deviate from
topics of this article and we will continue
talking about new types
computers on the Russian market
- notebook'ah.                  
   Now I’ll tell you about the essential
technical parameters
laptops. Let's focus on the important ones
moments that determine
division of laptops into
various classes.   First
turn, it's quality and size
monitor, memory capacity;   in
second - processor type, volume
hard drive and power
batteries.                  
   So for example everyone
the manufacturer strives
equip your computer with high
class with all the best, but with
this price is usuallydetermined by the cost of the matrix
and the amount of RAM.
Other additions (such as
built-in CD-ROM and processor
Pentium) just bring out the laptop
to a certain level
functionality, but
cost doesn't have the same effect
strongly.                         
   Let's consider from the point of view
user quality
display indicators and
batteries.                  
                                
           - DISPLAY.           
            1.Size.           
                                
   More or less normal
you can work with a display whose
size not less than 9.5"
diagonals;   at 10.4" none
inconvenience compared to
desktop computer at all
no.  This year 10.4 -
inch steel displays
equip computers with average
class.    Highest standard
steel grade dimensions: 11.3"
(Toshiba) and 12.2" (IBM).2.Display type.         
                                
   Most widespread
We received two types of monitors:
These are monitors with passive
double scan matrix
(monochrome and cvetnoy)and
color with active matrix.
It should be noted that
modern dual matrices
the scans are very good
clarity, color rendition and
brightness, but if we consider
quality desktop monitors
as a starting point, it is necessary
recognize that the matrix is double
scanning is worse than desktop
monitor, but active matrix
is not inferior to him. Passive and
are equipped with active matrices
all classes of laptops, and differences
consist in the number of colors,
brightness and efficiency.        
                                
          3.Resolution.In 1995the company NEC
released a laptop with a matrix
800x600 (established standard
640x480).      This matrix
characterized by increased
brightness, produced this
the impression that now many
laptop manufacturers announced
about the translation of their most prestigious
models on matrices with the same
resolution.                    
   Of course, the increase in the number
points affects and even very
on the price, but still standard
is 640x480, and this
the resolution is considered quite
acceptable to the eye.            
                                
        4. Batteries.        
                                
   Batteries directly affect
on the battery life of the laptop.
Understanding the importance of this issue,
laptop manufacturers
provide software
provision at the BIOS level,
by using which you can
make the computer track
workload level, and
if there is no need to translatethe processor is in "sleeping" state,
turn off display and hard drive
disk, reduce screen glow
etc.                         
   However, the better
battery, the longer you can
work offline. B
currently two are used
battery type:
nickel metal hydride and
"lithium ions"having 3-5
multiple excess capacity.
The first ones are usually placed
for cheap and mid-range models
price, the second - at elite.     
   As the survey shows, then
computer buyers
notebooks are pretty
wealthy people: bankers,
entrepreneurs, lawyers, in short
people who are commonly called
"new Russians", small
percentage of the total
buyers are occupied by people with
middle income: journalists,
accountants, employees
government institutions.     
   If you need a computer,
just to play, then no
the need to buy unusual,
high tech and very
dear notebook, better buy
regular desktop computer
desktopsome famous
assemblies.                         
   With this I want to conclude my
a story about a computer NOTEBOOK.  
   Make your own choice
you want to buy a computer,
I'll just say what's better
computer than ZX-SPECTRUMyou
just can't be found. Don't be lazy and
buy some reference book
on this computer and that's it
find out for yourself. Magazine readers
"PIONEER", you probably have in
at your disposal any
SPECTRUM-compatible computer and
appreciated it
possibilities, then not applicable
tell your friends about it
and advise them as soon as possible
buy this wonderful
computer.                      
   And finally I’ll say: small
NOTEBOOK, dear!   Wait

computers living in our
time, time of high technology
