ICT systems
ICT systems Learning Objectives • We are learning about: – The specialist ICT equipment that can be used – The use of microprocessor technology in commercial applications – Mobile, portable and desktop ICT tools – The differences between the technologies used and also the uses of these technologies
ICT systems Using microprocessors in organizations 1 • Microprocessors are used to control devices • They make decisions on how the device should operate • They operate actuators or turn devices on/off as well as make adjustments • They are also used in mobile devices such as mobile phones, PDAs, etc.
ICT systems Using microprocessors in organizations 2 Used to control air conditioning systems For controlling industrial processes For access control
ICT systems Operating Systems and applications software • Computer hardware needs the specialised software to tell it what to do. This is the operating system or applications software. • In PC’s this may be Windows 7 of Device Drivers.
ICT systems Applications of technologies ICT systems have to use a technology that is appropriate for their use. For example: Portable Devices: • Less powerful chips • Light • Small Screen • Less Memory • Long Battery life • Trimmed down operating system
ICT systems Magnetic ink character recognition (MICR) • These are the strangelooking characters on bank cheques • Characters are written in magnetic ink, which can be read automatically • Used by banks to read cheques at high speed • Very accurate and hard to forge
ICT systems Optical mark recognition (OMR) Optical mark recognition: • Works by shading in boxes on forms • Forms are batched together • Sent for reading by an optical mark reader • Reports can be produced from the system
ICT systems Graphics tablet • Used by designers • Can use the tablet to draw freehand • Some tablets have a series of shapes that can be chosen • Can add units and appliances, etc. , to a kitchen design
ICT systems Specialist output devices include: • A 3 printers • A 0 plotters • 3 D printers
ICT systems A 3 printers • A 3 paper is twice the size of A 4 paper • A 3 printers are larger versions of the more familiar A 4 printers • Used for posters, plans, etc. • Used for printing spreads for pages of books, magazines, etc.
ICT systems A 0 plotters • A 0 paper is very large • A 0 plotters can print in black and white and colour • Used for printing maps and plans • Ideal for CAD work • Used by architects
ICT systems 3 D printers • Can produce products in 3 dimensions • Ideal for producing 3 D prototypes of products • Architects can quickly produce models of buildings based on their plans
ICT systems Computers and portable devices • • WAP Laptops • Smart mobile phones Netbooks • Cloud computers Notebooks Palmtops Desktop computers Tablet Computers PDAs and Handhelds
ICT systems Software • Specialised software – – – Computer-aided design (CAD) Kitchen design software Payroll software Stock control software Expert Systems Control Software
ICT systems Task 1 • Download the worksheet from the intranet and have a go at the questions. • Extension: Complete the Test yourself task on page 195 of the text book.
