GNVQ INFORMATION TECHNOLOGY HARDWARE & SOFTWARE REVISION NOTES Name ICT GNVQ REVISION PROGRAMME FOR UNIT HARDWARE & SOFTWARE This unit helps you to: * understand ICT specifications for hardware and software * select an ICT system and configure it to meet the needs of users * write a program to improve efficient use of application software (macros) * write a program to display hypertext information (html) * understand and develop good practice in your use of ICT The topics are: * hardware * software * computer programming * html programs * macro programs * standard ways of working Hardware ICT systems are made up of hardware and software. You must learn to identify and know the purpose of the components (pieces) of hardware that make up an ICT system, including: * input devices * output devices * main processing unit * cables and connectors. Some hardware components are inside the main processing unit. You will need to understand the purpose of these and how they affect the ICT system specification, including: * disk drives (floppy, hard) * CD ROM drive * memory (RAM and ROM) * ports (input and output connectors) * motherboard * central processing unit (CPU) * data and software on computers can be stored in different ways. You will need to know the different types of storage used, including: * RAM (random-access memory) * ROM (read-only memory) * magnetic disk (hard, floppy) * optical storage (for example CD ROM, DVD) You will need to be able to compare the different types of storage for: * volatility (loss when power removed) * storage capacity * speed of access and retrieval * read capability * write capability * cost. ...read more.


* Clip-art * Simple shapes such as circles, rectangles etc. * Photographic images from a scanner or digital camera can be manipulated in a graphics package * Computer aided design programmes help architects and designers produce technical drawings * Other industries use graphics packages to help them with their work - e.g., fashion designers, publishing companies * Graphics files use a lot of memory so need a computer with a powerful CPU, a large hard drive and lots of RAM, together with a high resolution monitor and colour printer Personal Organisers * Schedulers or electronic diaries are used in many large companies to recors appointments, meetings, contact details etc. * Can be set up to provide reminders of important events or dates. * When used over a network they enable you to see when other people might be available for meetings etc and can save a lot of time in making telephone calls when trying to arrange a meeting. When a free slot is found, the meeting details can be entered in all the diaries at the same time E-Mail * An increasingly popular way to communicate with people all over the world * E-mails can be sent to individuals or a list of people. * Much quicker than telephone or letters * Data files can be attached to e-mails - e.g. a spreadsheet, database or word processed document. * The recipient can read the e-mail, save it, delete it, forward it to someone else or reply to you immediately Utilities * Often used to check the performance of a computer system * Most common is probably a virus checker, this scans all files, detects and removes viruses from floppy disks and hard drives. ...read more.


* call or create a new template * modify application software configuration (set options, customise) Templates A template is a blueprint for the text, graphics and formatting in a document. A Fax template for example contains the company name, a date field and placeholders to indicate where to type the recipient's name, address, fax and phone numbers, the number of pages and the message text. The benefits of a template are: * They can be used time and time again * They save time inputting basic data * They reduce errors * They mean that all documents based on the template have the same layout, so providing a consistent company image Standard Ways of Working Note: What you need to know and be able to do to implement standard ways of working is described in detail in Unit A: Presenting information (Intermediate). The following is a shortened version of these requirements written to apply specifically to this unit. To develop good practice in your use of ICT you must: * plan your work to produce what is required to given deadlines * keep a log of ICT problems you met and how you solved them * evaluate your work and suggest how it might be improved * proof-read your products (on screen) to ensure accuracy and economic use of material * keep backup copies of files on another disk and/or in another location * save work regularly using different filenames * keep information free from viruses * respect confidentiality * respect copyright When setting up or using ICT systems, you must be able to work safely. You must ensure that: * cables do not cause an obstacle hazard * cables and connectors are electrically safe * you replace consumable materials correctly * physical working environment and position (ergonomics) are acceptable D.M.Hislop Hardware & Software Revision Notes Page 9 ...read more.
