    Question

    1.      During a period of high market volatility,

    a Large-scale Institutional Investor sends a Limit Order to an electronic exchange. Due to a micro-congestion in the exchange’s fiber-optic router, the message arrives 15 milliseconds later than expected. By the time the order is processed, the price has shifted, and the trade fails to execute at the desired level. In the context of communication theory and information technology, this failure is best classified as _____
    A Semantic Noise caused by poor encoding of the limit price. Correct Answer Incorrect Answer
    B Psychological Barrier due to the investor’s Evaluation Apprehension Correct Answer Incorrect Answer
    C Systemic Noise within the communication channel. Correct Answer Incorrect Answer
    D Filtering, because the router purposefully ignored the message to protect the system. Correct Answer Incorrect Answer
    E Information Overload, as the investor sent more data than the exchange could legally handle. Correct Answer Incorrect Answer

    Solution

    In communication models (like the Shannon-Weaver model), noise is anything that interferes with the transmission of a signal from the sender to the receiver. Systemic/Physical Noise refers to environmental or mechanical interference. In the stock market, Latency (the delay in data transmission) is a form of systemic noise where the medium itself (the cables, routers, or servers) degrades the timeliness and accuracy of the message.   Note: ·        Semantic Noise: This would imply a misunderstanding of the meaning of the words or numbers (e.g., the computer misinterpreted "$" as "€"). Here, the meaning was clear; the arrival was late. ·        Psychological Barrier: This involves human emotions or biases. The router and the algorithm have no "apprehension." ·        Filtering: Filtering is the intentional manipulation of information by a human sender to make it look more favorable to the receiver. A router delay is unintentional and mechanical. ·        Information Overload: While the system might be busy, overload is a condition of the receiver being unable to process volume. Systemic Noise specifically describes the interference in the channel that caused the delay
