How Laptops Work
Thinking about buying a computer? Todays Latest laptops have
much more computing power than desktops, without taking up as
much space. You can take your laptop anywhere so that you can continue conducting your business and pick up emails while you travel around. You may be interested to find out how the laptop actually works, and why it is such a brilliant invention.
We will illustrate the parts of a computer laptop and show
you the Toshiba Satellite Pro laptop Insider View.
Toshiba Satellite Pro laptop:
Laptops have a central brain called a microprocessor Like all
computers, which performs all of the Computations and operations
of the computer.
A
laptop heat sink and fan
Usually laptops have small fans, heat sinks, heat spreaders
or heat pipes to help dissipate the heat from the CPU. Some
higher end laptop models reduce heat even further with liquid
coolant kept in channels alongside the heat pipe. Many laptop
CPUs are near the edge of the unit. This allows the fan to move
the heat directly to the outside instead of across other components.
The microprocessor
This has a set of internal instructions stored in memory and
can access memory for its own use while working. It can receive
instructions or data from you through a keyboard in combination
with another device (mouse, touchpad, trackball).
Memory and
Storage
Its memory can make up for some of the reduced performance that
comes from a slower processor. Some laptops have cache memory
on or very near the CPU, allowing it to access data more quickly.
Some also have larger busses, allowing data to move between
the processor, motherboard and memory more quickly.
Memory modules
Laptops even have upgradeable memory and feature removable panels
for easy access to the memory modules.
Like a desktop, a laptop also has an internal hard disk drive,
which stores the operating system, applications and data files.
But laptops generally have less disk space than desktops. A
laptop hard drive is also physically smaller than that of a
desktop. Moreover most laptop hard drives spin more slowly than
desktop hard drives, reducing both heat and power consumption.
Normal Desktop computers has multiple bays for installing additional
drives, such as CD and DVD ROM drives. But there is a space
problem in laptop. Many laptops use a modular design, allowing
a variety of drives to fit in the same bay.
