Study Notes
Computer Memory Concepts Quiz
- RAM's Role: RAM allows a computer to quickly access data for active processes.
- ROM Contents: ROM stores startup instructions and firmware for hardware components. It does not store temporary data like programs or settings.
- Virtual Memory Purpose: Virtual memory extends the amount of RAM available to a computer.
- Operating System Functions (Not): Compiling programming languages is not typically a function of an operating system.
- RAM vs. ROM (Data Retention): RAM is volatile (loses data when power is off), while ROM is non-volatile (retains data).
- Self-Driving Tractor Drawback: A potential drawback of self-driving tractors is that they can malfunction, causing delays in farming operations.
- Expert System Components (Not): A sensor array, user interface and inference engine are all components of an expert system. A knowledge base is also a component.
- Self-driving Tractor Data Transmission: The self-driving tractor communicates with the farmer's computer using a direct cable connection.
- Expert System Logical Rule Application: The inference engine applies logical rules to the knowledge base of an expert system.
- Common Misconception about Self-Driving Tractors: A misconception is that self-driving tractors can operate without any human supervision.
- Bit 3 in Byte 4 Value: The value of bit 3 in byte 4 is 1.
- Bytes with Bit Value 1: Three bytes have a 1 value in bit 1 (2, 3, and 4).
- Byte with 0 in Bit 6: Byte 1 has a 0 in bit 6.
- Bit 5 Value in Byte 6: Bit 5 in byte 6 represents the value 1.
- Byte with Most 1s: Byte 7 has the most 1s.
- Self-Driving Tractor Role in Echo Checks: The self-driving tractor's primary role during echo checks is to collect data and execute pre-programmed tasks.
- Parity Byte Purpose: Completing the parity byte ensures accurate data transmission by detecting any errors that might occur during data transmission.
- Purpose of Odd Parity: Odd parity ensures that the total number of 1s in the transmitted data is always odd.
- Drawback of Integrated Farming Technology: One drawback of self-driving tractors combined with farming technology is that they may operate independently, increasing the risk of accidents for the farmer.
- Farmer's Computer Assistance During Echo Check: The farmer's computer assists by providing real-time updates on tractor performance, which is crucial in the echo check process.
- Computer Data Representation Reason: Computers use binary because their internal components, like switches and gates, can only be in two states (on or off).
- ASCII Denary for Q: The ASCII denary number for 'Q' in 81.
- Binary Representation (Not): Binary representation is not easily understood by humans. Binary allows for faster processing than decimal, and binary can represent various data types.
- ASCII Meaning: ASCII stands for American Standard Code for Information Interchange.
- Binary Representation Digits: Binary uses two digits: 0 and 1.
- Binary Data Feature: A feature of binary data is that its processing involves simple on/off states. This usually makes processing much faster than other representations like decimal.
- Effect of Right Shift on Positive Integer: A right shift of four places on a positive binary integer divides the value by 16.
- Binary Integer Right Shift Action: When a binary integer is right-shifted, the trailing zeros are removed, and the value is halved.
- Right Logical Shift in Binary Arithmetic: A right logical shift places zeros to the right.
- Least Significant Bits (Right Shift): During a right shift, the least significant bits are discarded.
- Importance of Right Shift: Right shift operations in binary arithmetic make multiplication by powers of two very simple.
- Right Shift in Binary Integer: (Negative Impact): When a logical shift is applied to a negative binary integer, it retains the original negative value without change.
