Chapter 11 - Applications of IT Flashcards
Why should organisations embrace new technologies?
- Early adopters get ahead of competition
- Improve performance
- Quantity of data available that can be analysed through new tech
Define mobile technology
Technology that is portable
What are the advantages of mobile technology?
- Allows access to organisational info when away from work place
- Makes it easier for stakeholders to interact e.g. mobile tech to pay for goods
What are the disadvantages of mobile technology?
- Purchase costs
- Obsolescence
- Increases entry points for unauthorised individuals
Define cloud computing
Enabling network access to a shared pool of computing resources that can be rapidly released with minimal management effort
What are the advantages of cloud computing?
- More cost effective than in house
- Greater flexibility - lots of providers
- Accessible anywhere around world
- Available to small and large entities
What are the disadvantages of cloud computing?
- Give up control of data
- Data held by provider could be stolen, lost, corrupted
- Providers staff could interfere with data
- Failure to keep up with payments may lead to loss of data
Define the internet of things
Sensors embedded in physical objects which are capable of creating and sharing data across networks that function in a similar way to the internet
Define big data
The exponential growth and availability of data
What are the four V’s of big data?
- Volume
- Veracity - truthfulness
- Velocity - speed
- Variety - can be unstructured
What are the advantages of big data?
- Identify new trends and patterns
- Respond to changing conditions faster - competitive advantage
- Accurate and detailed performance data
What are the disadvantages of big data?
- Risk of hackers
- Collection does not guarantee that analysis will identify trends
- Costly to upgrade IT to be compatible
- Hidden biases?
Define information system
The systems & processes involved in collecting, storing, processing and distributing information
What are the different types of control for assessing adequacy of IT/IS controls?
- Physical access - preventing unauthorised individuals gaining access to IT assets
- Logical access - only authorised users of IT systems provided with access e.g. passwords
- Operational controls - ensuring day to day activities run effectively (segregation of duties, audit trail)
- Controls over data input - ensure accuracy and completeness e.g. data verification, control totals, data validation, limit checks, format check
Define audit trail
A record showing who has accessed a computer system and what operations the individual has performed
