ICTICT systemsASWJEC Created by: abbeyrose52Created on: 23-05-17 22:07 ADVANTAGES OF ICT OVER MANUAL METHODS: Speed of searching / accurate calculation / speed of data communicarions / repetitive processing / speed of processing / data storage capacity 1 of 17 ACCURATE CALCULATIONS: Calculations are carried out accurately (in a payroll spreadsheet if formula is correct then calculations will be correct) 2 of 17 SPEED OF DATA COMMUNICATIONS: Messages are sent out across the world instantaneously. 3 of 17 REPETITIVE PROCESSING: Carrying out the same task to the same standard repeatedly. 4 of 17 DATA STORAGE CAPACITY: Able to store an enormous amount of info in a small space such as a hard drive. 5 of 17 INSUFFICIENT TESTING: Has the system been checked in all sorts of situations. 6 of 17 MAINTENANCE PROCEDURE: Is there someone whos job it is to ensure that the data and software is kept upto date and has proper backups? 7 of 17 PROPER BACKUPS: Maintaining an incremental system. 8 of 17 EFFECTS OF HARDWARE: If the system has an old slow processor ti will take too long to process data, cost of upgrading. 9 of 17 EFFECTS OF SOFTWARE: Does the software put a big demand on the systenm 10 of 17 EFFECTS OF SOFTWARE: Does the software put a big demand on the system / does it work well with other software. 11 of 17 SUITABILITY OF OPERATING SYSTEM: If there is need for quick upto date info then there's no point running it on a batch processing system. 12 of 17 EFFECTS OF COMMUNICATION: Do the different devices talk properly to each other, does the final system fit in what was requested. 13 of 17 LIMITATIONS OF DATA PROCESSING SYSTEMS: Speed of implementation / Compatibility / Insufficient testing / Poor communication with the user / Maintenance 14 of 17 SPEED OF IMPLEMENTATION: Systems developed in a rush will likely have errors 15 of 17 COMPATIBILITY: Whether the new system works well with the existing data 16 of 17 INSUFFICIENT TESTING: Software wont do what it should do / contains bugs 17 of 17
