DTP Software

• Desktop Publishing Software e.g. Publisher• What is it used for?– Posters, flyers, leaflets

• What are the features of DTP?– Templates, word art, headers/footers, borders,

graphics• What are the advantages?– High quality, professional looking publications; ready

made templates; easily edit the layout; colour schemes are available

Data and Information

• Data consists of raw facts and figures• E.g. 17, 17, 18, 20, 20, 21, 22, 22, 23• No apparent meaning • BUT if told these are degrees centigrade, then

the data becomes INFORMATION

• Data given understanding is knowledge

Data + Meaning = Information

Bluetooth

• Wireless technology that allows devices to share files e.g. music, videos, pictures

• Connect phones to phones, to head sets, to speakers etc…

• ONLY small distances (personal area network) up to 10 meters

• NOT to connect to the internet!

GIS – Geographical Information Systems

• Uses a combination of hardware, software and data to manage, analyse and display all kinds of geographical data

• E.g. maps, charts, reports• THINK ABOUT maps and location services on

phones• What are the advantages? What are the

disadvantages?

Internet Connections – Dial Up• Dial up – using telephone system to connect to

the internet. Required modem which made sure digital signals from computers were compatible with those of telephone lines

• ADVANTAGES: most residential phone lines are capable of supporting dial up so can be in areas where broadband is unavailable; Also, users can dial up from different locations

• DISADVANTAGES: Slow download speeds; blocks phone line while using the internet; practically impossible to watch videos or download music

Internet Connections - Broadband• Includes ISDN and ADSL• Uses digital signals so no need for a modem• Fast speeds and permanently connected• Does not block the phone line and several

computers can be connected at once – including wirelessly

• BUT speeds vary according to other local usage and distance from the exchange

• Greater risk of hacking due to being permanently on

Online Shopping

• Almost anything can be bought online nowadays• Think about your own shopping experiences• What are the advantages? (save petrol, people

with disabilities, range of goods, items delivered incl. heavy items, businesses can easily expand internationally, no overheads etc)

• What are the disadvantages of shopping online? (wait for delivery, only see the goods – cannot touch them or try them on, pay to return items, items could be damaged etc)

Email: CC, BCC and attachments

• Cc – Carbon Copy. Used to send a copy of the email to someone else

• Bcc – Blind Carbon Copy. Used if you don’t want the main recipient of the email to see who else you have copied it to

• Attachments can be any file stored on a computer e.g. picture, sound, document

• BUT restrictions on file size

Spreadsheets

• Benefits: automatic recalculation; graphs and charts can be created easily, replication of values and formula in a column or row, formula can be stored and reused, easy to calculate large amount of values

• If asked for formula ALWAYS start with “=“ and use cell references

• E.g. =A1+A2 =SUM(A1:A5)

Data Logging and Control• Data logging allows you to record a series of

measurements taken by sensors• Results are logged and stored on a computer for later use• Data can be collected automatically at set intervals e.g.

temperature, air pressure, humidity, • Advantages: data collection is automatic – no intervention

is necessary; readings taken continuously over long periods of time; readings more accurate; sensors can be placed in areas too dangerous for humans

• Control Systems – use sensors to control a computer e.g. environmental control

• Measurements are analogue (e.g. temperature) and so need to be converted to digital using an Analogue to Digital Convertor (ADC)

Devices for Specific Users

• Voice-recognition software• Text-to-voice software• Braille Keyboards• Touch-sensitive data entry devices (e.g. touch

screens)• Eye typer• Foot mouse

Databases (Information Handling)• Benefits: fast access – finding data is quicker that in a

system where data is stored on paper; easy to edit – easy to find data and update it; validation – checking that the data being entered is appropriate (GIGO); Reports – results can be used to produce printed reports; Security – can set passwords

• RECORD – the whole information about one thing e.g. a person

• FIELD – one piece of information within a record e.g. Address

• TABLE – all records e.g. customers• PRIMARY KEY – unique identification of a record to make

sure each record is unique e.g. Customer ID, Product ID

Databases – Searching for Information

• Use queries to search for information• Simple search – looks for data in one field only

e.g. Town = Beaconsfield• Complex search – looks for data across

multiple fields e.g Town = Beaconsfield AND Age >16

Electronic Registration• Most schools now use computer registration for students• In this school – SIMS• Makes it easy to determine whether a pupil is absent and

highlight patterns in absenteeism• Some schools use swipe card registration or OMR (optical

mark recognition)• SIMS can be used on laptop, PC or iPad• Biometric (fingerprint) registration is now much more

common• Statistics can be easily and quickly found for heads of year –

computer works it all out for them!

Online Bookings• Holidays, cinema, activities etc• Many booking systems are now web based and can be

booked over the internet• Can check whether seats/rooms are available and how

much the are• Payment usually by credit card• Tickets can be mailed through the post or emailed to be

later printed• A large database is actually used to store the companies

bookings and must ensure double bookings cannot be made

• Advantages/Disadvantages?

Examinations

• The written exams are 40% of the entire course

• In May you will sit two exams of 1.5 hours• When you are in the exam there are three

golden rules:1. Read the question2. Read the question 3. Answer the question

Banned Words!Never use words such as “thing”, “something” or “stuff”BAD : A thing for reading stuff on shopping itemsGOOD : A device for reading barcodes on shopping items

Never use words such as “quicker”, “easier” and “cheaper” – you will usually only score marks if they are qualifiedBAD: An email is quicker, easier and cheaperGOOD : An email is easier to send than taking a letter to a post-box. It can be quicker to receive a reply as it arrives in a persons inbox instantly and it is cheaper than buying stamps.

Always make sure the examiner can understand your answer – try to avoid using the word “it”BAD : It is fasterGOOD : Serving customers is faster because…
