ICT GCSE Lesson Plans

Personal Digital Devices

You need to be able to explain how the use of personal digital devices affects everyday life.

Digital devices allow people to communicate For Leisure For Travel
  • text messages
  • social networking sites
  • IM (instant messaging)
  • MMS Media messages
  • Voice calls
  • Video calls (SKYPE, VOIP)
  • Emails
High definition TV, Stream films, Music, Reading (E Book), Consoles, Digital photos Use deices on the move, GPS (Global positioning System), Tracking cars & vans

 

Using Digital Devices

Digital devices perform different things with many functions.

Audience & purpose Wants versus needs Important factors to consider
Designs of devices are thought of when you think of whom will be using and how.

e.g. older people need large screens, business person needs qwerty keyboard to write documents faster.

When choosing a digital device its important to weight up the wants  needs.

e.g wide screen but something portable

  1. battery life
  2. weight & size
  3. cost
  4. security
  5. reliability
  6. speed of internet connection & processor
  7. compatibility

 

 

Common Features

Processor There is a processor in all digital devices. It controls all functions. There are special micro processors.
Internal memory Memory is needed to store the program instructions and data. This is measured in bytes. **
Digital devices can store data i.e. computer contain high capacity hard disk. These are not portable as they contain moving parts.

 

Flash Memory This is a type of peripheral that is portable because:

  • It doesn’t lose data when turned off
  • It has no moving parts (solid state)
  • It is removable and can be used to transfer data
Types of flash memory – Secure Digital (SD) card stores up to 4GB
– Micro SD
– SDXC card stores up to 2 TB
– USB flash drive or memory stick stores up to 256 GB
– SDHC (high capacity) stores up to 32GB

**1 byte 1 kilobyte (KB)

= 1000 bytes

1 megabyte (MB)

= 1000
kilobytes

1 Gigabyte (GB)

= 1000 Megabytes

1 Terabyte (TB)

= 1000 Gigabytes

The memory size increases by multiples of 1000

 

Input & Out Devices

There are 3 types of Peripherals: storage devices, input devices (allow users to give instructions) and output devices allow users to see or hear after it has been processed.

Storage Input Output
Hard drives

USB
SD cards…

Mouse

Keyboard

Game controller
Webcam

Speakers

Docking stations

Printer

Headphones

Screen

Connectivity

Digital devices connect to each other and share data.

 

Data cable connection Most common methods of data cable connection is a USB cable.
Bluetooth Allows wireless communication over short distances. Most devices can now connect to outputs devices such as printers and speakers.
Cloud synchronization Now that people have more wi fi enabled devices services such as I Cloud and drop box allow them to store and access files on a remote server.

 

 

 

Personal Computer

Desktop computers need input & output devices, hard disk drives & optical drives (CD &DVD). Connectivity with USB, blue tooth, HDMI. Easy to upgrade.
Laptops Powered by battery or electric supply. Built in input & output devices. Hard disk drives, optical drives & slots for SD cards. Less easy to upgrade.
Netbook computers Strong & robust. Small & Lightweight. Bootup quickly. Solid state SD cards as storage. No hard drive or optical drives (normally). Designed for internet & “cloud” computing.
Tablet computers Light & portable, battery powered. Touch screen. Virtual keyboards, cameras, designed for playing media & ebooks. Run apps like mobile phones.
