Description

Understand the difference between Information categories and information elements o Information Category 1  Information element 1  Information element 2  Information element 3  Information element 4 o Information Category 2  Information element 1  Information element 2  Information element 3  Information element 4 Understand the differences between business requirements, technology requirements and design specifications

Understand differences between transactional, tactical and strategic activities Transactional activities (Execution and decisions) o Locating/finding past records on systems so as to understand what has happened o Creating a new action or record based on a new request o Changing past record or updating a past record based on new events that has happened o Documenting the closing or completion of a business activity o Requesting authorization and access to resources needed to complete the next step of a business activity Tactical activities (Control) o Compare current business results with the level of performance that was achieved in prior periods o Compare current business results with the level of performance planned o Compare ending business results with the resources at end of period Tactical activities (Planning) o Estimate the type and kind of resources that are needed to accomplish specific outcomes in a period o Allocate different resources to departments that have to be achieved in a period o Assign responsibilities for outcomes to specific departments and results o Schedule the mode in which activities have to be accomplished in the period Tactical activities (Learning, diagnosis, prescription) o Understanding a situation or problem more thoroughly o Understanding the weaknesses and strengths of solution options more thoroughly o Understanding the causes of a problem more thoroughly

What is the concept of Total Cost of Ownership (TCO)? The principle of TCO holds that the best way to make decisions about technology products is to consider the reasonable costs that will arise over the life-span of the technology. Any given acquisition might include any or all of the following:  the original leasing price (licensing)  software maintenance agreements  implementation and integration costs  software customization  hardware upgrades  training of technical and end users  hiring additional MIS/IT personnel  the subsequent purchase of additional licenses or system modules What are two differences between tasks that operating systems perform and those which functional software perform? Operating systems (OS) software - A group of interdependent computer programs that provide the rules, functions, and controls needed to control computer hardware and the processing that computer hardware perform. They are used to perform general control tasks related to activities of hardware.  Select the printer to use for printing.  Determine which secondary storage is used to save files  Determine how many people can work concurrently on a RAM  Changing the language that will be used on a computer.  Organize how data will be stored on the hard drive.  Determine how to change the resolution of your monitor  Determine if erased files can be undeleted  Determine how to create folders on a computer  Determine how commands are activated by users (graphical versus non-graphical user interfaces). Functional software: These products are primarily for supporting and enabling business processing at the operational, tactical and strategic levels in an automated, and standardized way. They have graphical user interfaces for interactions. Also, called vertical software.

What activities fall into following tasks: planning, decision-making, control, information gathering, analysis and execution? What are two differences between closed source (proprietary) and open source software? Proprietary (Closed Source)

Open Source Software

Ownership

Software is owned by a company or individual

Software is not owned by a company but by a community

Distribution of code

Only the complied code is distributed to people

Both the complied and source code are distributed to users

Copyright

A copyright license limits how users are permitted to use the software code

Open source license broadly permits users to use modify and even re-distribute code software code

Purchase cost

Varies from moderately to very expensive

Varies from free to low cost

What are two characteristics of open source software?

What are two advantages of database-centric applications? What are two differences between single user and multi-user functional software? What are the key components of a wide area network? What is Moore’s law and what are some of its impacts? What do primary and foreign keys do?

Understanding of different types of database What is the definition of the Information Lifecycle management (ILM) approach?

What are key elements of the ILM approach? What is Metcalfe’s law?

Understand the three types of local area network (LAN) topologies What are key components of a wire-based LANs?

What are key components of a wireless LANs? Understanding the function and range of RFID and 4gLTE technologies

Understanding the types of operating systems that would be used on larger hardware systems...
