Unit 3 discusses different computer systems such as laptops, smartphones, and desktop PCs. It explains that laptops are portable personal computers that contain the same components as desktops but have a different form factor and motherboard. Laptops allow users to access the internet, play games, and create documents on the go. Desktops are stationary and consist of a monitor, keyboard, mouse and tower, while tablets are portable computers with touchscreens and keyboards. The document also outlines servers, smartphones, games consoles, embedded systems, and driverless cars.

2. Unit 3 is all about different computer systems such as
laptops, smart-phones, etc. It is also about the
components inside the computer, (P1).
In this particular pass task, I have to identify and
explain the different computer systems, such as
desktop, laptops, smart-phones, etc.

3. Laptops are personal and portable computers. They serve the same
function as desktop computers and contain all of the same
components, however, instead of a mouse, there is a touch pad and
the form factor is different, which means that there is a different
Motherboard. The touchpad is an input device. When using a laptop,
you can do a lot of different things, such as accessing the internet,
playing games, creating and editing documents, ordering shopping,
etc.
One of the main advantages of laptops are that they can be used
anywhere, due to the lack of ports and cables. This makes it more
practical to use.
As technology improves, touchscreen laptops are becoming
increasingly popular. The touchscreen is also an input device.

4. A desktop computer is not portable, it is stationary. You
can do nearly everything that a computer can
do, however, you can’t use it on the move and whilst
travelling. It consists of a monitor, keyboard, mouse
and a computer tower. It also has many ports and
cables to allow connection to the router for the internet
and other peripherals.

5. A tablet is a small computer that can be taken
everywhere. It usually has one main button and has a
large touch screen. There is a virtual keyboard and
usually a camera. You can access the internet, play
games, create documents, e-mail people, etc. The
form factors are also different to desktop computers
and laptops.

6. A server is a group of computers that allows different
devices to connect together and share data. This
usually happens across a network, either over a LAN
or WAN. There is more than one, type of server, such
as internet and file.

7. Smart phones are just like usual
phones, however, they have extra and better
features, such as accessing the internet, purchasing
and downloading apps and they have a QWERTY
keyboard instead of a few buttons with more than one
letter and you can send e-mails. The screens are often
larger and most of them are touchscreens.

8. A games console is a device, used to play video
games. They range from portable ones, such as the
Nintendo DS range, (Nintendo DS, DSi, DSi XL, 3DS)
to ones that are wired up (XBOX 360, Nintendo
Wii, PlayStations, etc.) They usually have a couple of
buttons on the front, (power button, eject button, reset
button, etc.) and a place to put the disk. They can be
wired up to the television, using the sound and audio
cables (red, yellow and white). As technology has
developed, more games consoles are now wireless
and can be played anywhere.

9. An embedded system is a system used in cars, planes
and other larger resources which have specific
instructions programmed into them. “Typically, an
embedded system is housed on a single
microprocessor board programs stored in ROM.”

Sometimes, there is an operating system, but not in all
circumstances.

10. The Google Car is known as “the car from the future”.
This is because it is the first driverless car. The body of
a normal car can be used with the technology. For
example, during testing, a Toyota Prius, Audi TT, and a
Lexus RX450h were used. The cars have travelled
300,000 miles and there have been no recorded
accidents.
