P2 – All about Computer Systems

By Cammie Hall

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.

Laptops

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.

Tablets can connect to the internet wirelessly. Tablets can connect to laptops or desktops by using a external cord

that saves the data from the tablet to the laptop or desktop like a daily backup. This information can also be saved by using the cloud

Depending on the type of tablet that you have you, may be able to message or video chat to those with tablets.

It contains quite a long battery life, which also depends on usage.

Desktop

A desktop also known as a PC (personal computer). A desktop was the first computer that was originally designed for military

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.

Server

A server is a host computer networkIt can offer multiple things such as; database server,

file server, mail server, print server, web server, gaming server etc.

Server run on IP (Internet Protocol)They provide essential services across a networks

from private (networks) to public (Internet) .A common use of servers is that files can be shared

across a network.

Smart Phones

A smart phone is a average phone but is built using a mobile operating system.

They can also be known as PDA's (Personal Digital Assistant).

More modern versions of smart phones contain digital cameras, media players, GPS, Wi-Fi, broadband, 3G or 4G.

The latest smart phones are touch screen. There are 8 common mobile operating systems. Most smart phones have a high resolution. All smart phones are expensive ranging from £70 to

£300

Game Console

Is a form of entertainment. These are some sort of game that use a display device

(monitor, TV screen). As technology has developed so has the gaming industry,

making games more realistic and giving them a higher resolution.

More modern game consoles connect to the internet to give an extra feature to there games and there gaming experience.

Also more can be done that doesn't involve games, for example people can browse the internet and chat to friends on a extra feature that can be downloaded.

Embedded Systems

Is a computer systems designed to control a larger system eg a car or plane

It often contains hardware or mechanical parts.It was designed to be a flexible design to appeal to a

variety of users.Embedded systems are designed specifically for one

system.

Thank you for viewing my Power Point I hope that you learnt all about how computer systems are in

our day to day life.
