Capabilities And Limitations Of ICT Essay Sample

Advantages of ICT Over Manual Methods of Processing Data
• Insistent Processing – Computers can transport out the same or similar undertakings ( e. g. mail merge. paysheet ) over and over really rapidly and with a high degree of truth.

• Speed of Processing – A computing machine system can treat natural informations really rapidly to bring forth information.

• Data Storage Capacity – Traditionally. a company’s information would be stored on paper in registering cabinets which takes up expensive storage infinite. A computing machine system can hive away the same sum of informations in a fraction of the infinite. Other advantages include the ability to backup informations easy and increase security by watchword protection or encoding.

• Speed of Searching – Another large advantage of a computerised information storage system over a paper based system is that hunts are virtually instantaneous.

• Speed of Data Communications – Data can be sent from one side of the universe to the other in a affair of seconds via the cyberspace ( e-mail ) compared to yearss utilizing traditional station ( ‘snail mail’ ) .

• The Ability to Produce Different Output Formats – Information can be end product from a computing machine system. either on-screen or printed. in the signifier of graphs. charts. studies. images. sound etc.

Factors Affecting the Efficiency of Data Processing Systems. • Input ( GIGO ) – Even the most advanced informations processing system will give inaccurate information if the information input is non accurate.

• Hardware – The system must integrate suited hardware for the system to work expeditiously ( e. g. a barcode scanner in a store or library. a schemer in architect’s office or a powerful processor and artworks card in a CAD/CAM system.

• Suitability of the Operating System – The right pick of operating system is critical for a system to work expeditiously ( e. g. a existent clip control system for air traffic control. a existent clip dealing for ticket gross revenues or a batch processing system for paysheet or charge )

• Software – There are a figure of jobs that may originate when choosing appropriate package particularly if the package is to be developed for a specific intent: O Possible alterations in fortunes during development

o Time taken to implement the package
o Compatibility of the new package with current hardware and informations o Fiscal Costss
o Insufficient proving ensuing in ‘bugs’
o Poor communications with the user – the solution may non run into the user’s demands

o The ability of the user – will they need any preparation
o Maintenance jobs ( perfective. adaptative and disciplinary ) o Technical support.
