Easy to upgrade and enhance by adding extra components/functions Can have WiFi cards fitted for wireless communication Desktops needs to have peripheral devices connected to it, such as, a monitor, a printer, a mouse, and a keyboard. Personal Computer – Laptops Battery powered or can use electrical supply Monitor, pointing device, webcam built-in Hard disk drives and optical drives e.g. CD/DVD drives, SD slots. Bluetooth and WiFi built-in Good connectivity (USB, FireWire, HDMI) Less easy to dismantle and upgrade Notebooks are similar but even more compact A notebook computer is likely to be half the size of a laptop and is lighter and easier to  Personal Computer – Very small laptopNetbooks that is optimized for internet and email access. It is intended to be light and easy to carry and has a long battery life. Boot up very quickly – used immediately WiFi built in No hard disk or optical drives Solid State SD cards as storage devices – less likely to be  Personal Computer – Tablet Bigger than smartphone, but have similar features. Very light and portable Battery powered Virtual, on-screen keyboard Bluetooth, WiFi, 3G for wireless communication Cameras for still and moving images  Mobile Phones 🠶 Mobile phones use a SIM card to connect to a mobile phone network. 🠶 SIM stands for Subscriber Identity Module. 🠶 A SIM card is used to identify the subscriber to a mobile phone network. 🠶 Types of mobile phones: o Specialist Phones  Mobile Phones – Specialist Phones These have special features that provides functions that meet particular user needs. For example, some phones have an emergency button that is linked to a list of emergency contacts.When this button is pressed, the phone will call each person on the list until someone answers. Other specialist phones meet user’ accessibility needs e.g. the Alto 2 ‘talking phone’ which is a specialist phone for Mobile Phones – Smart Phones Originally designed to make call while on the move. Small computers with Wi-Fi and mobile phone connectivity to allow them to make phone calls and access the internet. A virtual keyboard to enter text, numbers and other characters. Camera/video camera – video calls. Internet browsing – stream music and videos GPS receiver – to pin point position on a map, get local information, navigational device. Entertainment – play music/videos, play games Productivity – learning, financial management, travel apps, boosts productivity and saves time. Data storage – store photo/music/video, removable storage (e.g. SD Card) Cameras and Camcorders - Functions 🠶 Zoom in using optical or digital zoom 🠶 Take photos/record video and sound 🠶 View videos or photos on an LCD screen 🠶 Store files with SD and micro SD cards 🠶 Crop and edit files using inbuilt software 🠶 View files on TV using USB and HDMI ports. 🠶 Download files to a computer using USB or  Home Entertainment Systems – Television 🠶 Television display still and moving images on a screen. 🠶 The quality of the image is set by the resolution (i.e. number of pixels that are used to display the image). 🠶 High Definition (HD) TV screens contain a large number of pixels, which means they have higher resolution. 🠶 The resolution of a TV pixels is stated as o Horizontal Pixels x Vertical Pixels 🠶 For example, 1280 x 720, 1920 x 1080 etc… 🠶 Ultra High Definition (UHD) television screens are sometimes called 4k or 8K because they have Home Entertainment Systems – Sound System 🠶 Sound systems can produce loud, rich sound using high- quality speakers and amplifiers. 🠶 Can play music from CDs or from local storage. 🠶 Can be connected to personal devices like smartphones, media players and tablet devices using wired connections like USB or wireless connections like Bluetooth. 🠶 Can be connected to a LAN via Wi-Fi to play music that is stored on connected devices.  Game Consoles 🠶 Game consoles are designed to enable users to play video games on a television screen. 🠶 Games are provided on disks or downloaded from the internet. 🠶 The use of controllers, which are often wireless, to control the characters, vehicles and/or objects in the game. 🠶 Some use motion sensors to allow the player control the game with gestures and body movements.  Media Players 🠶 Media players provide video and audio content to a television. 🠶 Content could be streamed directly from the internet or accessed from a local storage. 🠶 Media players can be connected to a television directly of using a wired or wireless network. 🠶 They are controlled using a remote control, or in some cases, smartphone app.  Navigation Aids 🠶 Navigation aids (Sat-Navs) use GPS to calculate the best route between two or more locations and can provide updates to the route if it is not followed accurately. 🠶 They are commonly used in cars, delivery vans and ships. 🠶 Navigation aids use information from GPS satellites to determine the exact location of the device on Earth. 🠶 GPS does not need internet connectivity to work, however, navigation aids need internet connectivity in order to update map data. Home Automation Devices & Smart Assistants 🠶 Home automation devices are emerging technologies that can be used to create smart homes. 🠶 For example, they an connect a range of digital devices which sense and control functions in the home, such as temperature and lighting. 🠶 These functions can be controlled from apps on smartphones or the  Multifunctional Devices 🠶 A smartphone is a type of mobile phone, which means that its primary function is to make phone calls. 🠶 It can also be used to take photographs or to function as a navigation aid, fitness tracker, music player or handheld games console. 🠶 Because it can perform a range of different functions, it is classed as a multifunctional device.  ACTIVITY Multifunctional Devices -Identify another example of multifunctional device - What is the primary function? - What else can it do? Convergence Convergence is when a digital device takes on the functions normally found on another device.  Convergen 🠶 GPS, for example, is now found ce on smartphones and sales of SatNavs are falling because of this. 🠶 They are different in that a smartphone has mobile phone network connectivity and is smaller than a tablet device. However, newer smartphones are getting bigger to look more like tablets (phablets) , while tablets devices can now connect to mobile phone networks. 🠶 Similarly, most smartphones have digital  To-Do Connecting Devices – Convergence - Research the differences and similarities between smartphones, tablets devices and touch screens laptops. [email protected] rg
