IT Fields Overview

IT Fields

• Computing: The broad use of computers to process data, solve problems, and execute instructions. Involves many different types of computer systems and algorithms. Used in banking, remote work, and gaming.

• Computer Science: The study of computers and computational systems. Focuses on theoretical foundations, algorithms, and problem-solving techniques. Used in research, data analysis, artificial intelligence development, system optimization, and software creation.

• Software Engineering: The systematic application of engineering principles to software design, development, testing, and maintenance. Focus is on creating high-quality, scalable, and maintainable software systems. Includes large-scale software development, project management and application in telecom, automotive, and robotics.

• Computer Engineering: Combines computer science and electrical engineering to design hardware and software systems. Focuses on both hardware components (processors, microcontrollers) and software integration. Involves circuit design, embedded systems (e.g., automotive), chip design, robotics, and computer system architecture.

• Information Systems: An interconnected set of components designed to gather, store, process and transmit data and information. Applications of technology within a business context, not focused on core development of hardware or software. Includes business data management, IT infrastructure, decision support systems, data analytics, and enterprise information systems.

Professional Organizations

• IEEE (Institute of Electrical and Electronics Engineers): A professional organization in the electrical and electronics fields.

• BCS (British Computer Society): A professional organization in the UK focusing on computing.

• ACM (Association for Computing Machinery): A global organization for computer science and related fields.

• AIS (Association for Information Systems): A professional organization focusing on information systems.

Data, Information, and Knowledge

• Data: Unprocessed, discrete, unorganized information (e.g., temperature, humidity readings). Can be qualitative or quantitative.

• Information: Processed, organized data, making it easier to understand (e.g., computer simulation predicting tornadoes).

• Knowledge: Insights, understanding, or expertise gained by interpreting information.

• Feedback: Information that can be reprocessed and is technically considered data.

Information Sources

• Traditional: (e.g., CD-ROMs, DVDs, journals, catalogues, magazines). Often have lower reliability, subjectivity, and are not readily updated.

• Electronic: (e.g., electronic databases, websites). Offers broad information and quick search but may vary greatly in credibility. Can be highly updated.

• People: Provide firsthand information and can clarify details but credibility can be low, reliability weak, and very subjective.

Characteristics of Information

• Availability: How easily accessible the information is.
• Cost: The price or expense to acquire information.
• Currency: The timeliness and recency of the information.
• Reliability: The accuracy and trustworthiness of the source.
• Format: The structure or arrangement of the information.
• Medium: The form (e.g., print, digital) in which information is presented.
• Breadth of coverage: The scope or comprehensiveness of the information.
• Amount of detail: The depth of information provided.

Information Systems

• Manual Information Systems: Rely completely on human tasks to gather, collate, analyze, present and disseminate information.

• Automated Systems: Use information systems with hardware, software and networks to automatically process data into information. Types include transaction processing systems, manufacturing/production, sales/marketing, human resource, decision support and management information systems.

Data Types

• Characters: Letters, numbers, and symbols
• Strings: Ordered sequences of characters.
• Aural: Audio data
• Visual: Images, graphics
• Numeric: Numbers

Information Types

• Text: Written words
• Graphics: Images
• Signals: Electrical or other signals
• Sound: Audio data
• Video: Moving images
• Special-purpose notation: Unique symbols (e.g., musical notation)
• Graphical: Visual representations
• Tables: Data arranged in rows and columns

Information Tools

• SMS: (Google Voice)
• FTP: (FileZilla)
• Message boards: (Reddit)
• Mailing lists: (Mailchimp)
• Social media tools: (Hootsuite)
• Web conferencing tools: (Zoom, Google Meet)
• Cross-platform messaging tools: (Telegram, WhatsApp)

IPOS Cycle
