
Although they are similar in many ways a laptop and a desktop computer are
very different.

Laptops are potable computers designed for people on the go.

Laptops can either be plugged into there AC adapter or use there
rechargeable battery as a source of power.

Throughout the years laptops have technologically advanced, this is through
becoming lighter, cheaper and the software in laptops has developed
dramatically, also there uses have increased making them appeal to a wider
range of customers.

Laptops have the same internal components as a desktop but there internal
components are smaller and are usually described as miniaturized. And
because of this it limits the overall performance of the Laptop.

3. Tablet

Tablets are the latest technology breakthrough in portable devices
that are similar to desktop and laptops.

A tablet is primarily operating by using a touch screen, so no external
components like a mouse or a keyboard is needed.

They sometimes come with a stylus pen or can be used using your
finger.

purposes.

A desktop consists of a tower, monitor, keyboard and mouse.

In more modern computers desktop monitors can be touch screen.

Desktops have advanced dramatically in software and hardware.

Desktops tend to be cheaper than the average laptop and parts tend to be
cheaper.

They have a larger overall maximum performance compared to Laptops
because they have no limitations.

Desktops are used for more professional purposes but software’s have been
made and they now appeal to a wider target audience.

It was designed to be a flexible design to appeal to a
variety of users.

Embedded systems are designed specifically for one
system.

I hope that you learnt all about
how computer systems are in
our day to day life.
