Fundamentals of Business Communication and Information Technology
Fundamentals of Business Communication and Information Technology tests the communication process and barriers, business messages and reports, and foundational IT concepts including hardware, software, networks, databases, spreadsheets and security.
Core rules
- Communication process: sender encodes a message, chooses a channel, receiver decodes, and feedback confirms understanding; noise is any barrier.
- Barriers include semantic, psychological, organizational, physical and cultural. Listening differs from hearing.
- Formal channels follow the hierarchy; the informal grapevine is fast but unreliable. Channel choice depends on richness, urgency and need for a record.
- A report typically states purpose or terms of reference, procedure, findings, conclusions and recommendations.
- Hardware is physical equipment; software is instructions. System software includes the operating system; application software performs user tasks. RAM is volatile; storage is non-volatile.
- LAN covers a small area; WAN covers a wide area. A DBMS stores structured records; a primary key uniquely identifies a row. Security aims at confidentiality, integrity and availability.
Worked example
In a spreadsheet, basic pay is in B2 = 20,000; HRA in C2 is =B220%, giving 4,000; gross in D2 is =B2+C2, giving 24,000; tax in E2 is =IF(D2>25000,D210%,0), giving 0; net in F2 is =D2-E2, giving 24,000. If basic were 25,000, gross would be 30,000, tax 3,000 and net 27,000.
Traps
Do not assume email is always the richest channel. More data does not guarantee better communication. Do not confuse RAM with storage or hardware with software. Check relative versus absolute spreadsheet references. Phishing is deceptive message-based credential theft, not merely unwanted advertising.
