If MARIE has 4K words of main memory, addresses must have 12 bits because each bit can represent two states (0 or 1), and 2^12 equals 4096, which is the same as 4K (4 x 1024). Therefore, 12 bits are needed to uniquely represent all 4096 memory locations in the 4K words of main memory.

In order to access each of these words, we need a unique address for each one. Since each address must be unique and there are 4,000 words in the memory, we need at least 12 bits to represent all possible addresses. This is because 2^12 = 4,096, which is greater than 4,000. Therefore, addresses must have 12 bits to be able to access all of the words in the 4K memory.
In terms of how many words can be stored in the memory with 12-bit addresses, we can use the formula 2^n where n is the number of bits. So, 2^12 = 4,096 words can be stored in the memory with 12-bit addresses. If we want to answer how many words can be accessed by a specific 12-bit address, the answer would be 100 words. This is because each address represents a unique location in memory, and since there are 4,096 possible addresses with 12 bits, each address would represent 100 words (4,096/100 = 40.96, which we can round down to 40 since we can't have a fraction of a word).

In general, an asynchronous bus would be more appropriate for use between the CPU and memory, as it allows for more flexibility and efficiency in data transfer.

An asynchronous bus operates independently of a clock signal, meaning that data can be transmitted between the CPU and memory at any time, without waiting for a clock cycle to start. This allows for faster and more efficient data transfer, as there is no need to wait for the clock signal to synchronize data transmission.In contrast, a synchronous bus operates on a clock signal, meaning that data transfer is synchronized with the clock cycle. While this can provide more precise timing and synchronization, it can also result in slower data transfer and potentially limit the amount of data that can be transferred at once.For CPU-memory communication, where speed and efficiency are crucial, an asynchronous bus would be the better choice. However, the choice of bus architecture will depend on the specific requirements of the system and the tradeoffs between speed, synchronization, and complexity. Ultimately, the decision should be based on a careful analysis of the system's needs and performance requirements.

C. Explicit memory access is not an i/o control method.

Out of the four given options, "explicit memory access" is not an input/output (I/O) control method. Programmed I/O is a simple and direct method where the CPU issues read/write instructions to the I/O device. Interrupt-driven I/O, on the other hand, allows the CPU to perform other tasks while waiting for the I/O device to signal that it has finished its operation. Channel attached I/O uses a dedicated processor called a channel to manage the data transfer between the CPU and the I/O device.

Explicit memory access, on the other hand, is a term used to refer to the process of accessing specific memory locations directly, bypassing the normal I/O channels. This method is typically used in low-level programming tasks, where direct memory access is required to optimize performance. However, it is not a standard I/O control method used in typical computer systems.

In conclusion, programmed I/O, interrupt-driven I/O, and channel-attached I/O are all standard I/O control methods used in modern computer systems. Explicit memory access, while a valid method in certain cases, is not typically considered an I/O control method. Therefore, the correct answer is option C.

The three potential situations that can arise when a try block executes are No exception occurs, An exception occurs and is caught and An exception occurs but is not caught

1. No exception occurs: In this situation, the code within the try block runs successfully without encountering any exceptions. When this happens, the catch block(s) are skipped, as there are no exceptions to handle. If there is a final block present, it will execute after the try block, ensuring that any necessary cleanup or final operations are performed.

2. An exception occurs and is caught: If an exception occurs within the try block, the program immediately stops executing the remaining code within the try block and jumps to the appropriate catch block that matches the type of the exception. The catch block then handles the exception, allowing the program to recover gracefully and continue executing. After the catch block, the final block (if present) is executed to perform any necessary cleanup or final operations.

3. An exception occurs but is not caught: In some cases, an exception might occur within the try block, but there is no matching catch block to handle it. In such situations, the program stops executing the remaining code within the try block and jumps to the final block (if present) to perform any cleanup or final operations. After the final block, the unhandled exception propagates up the call stack, potentially causing the program to terminate if it is not caught at a higher level.

These three scenarios demonstrate the flexibility and importance of using try, catch, and finally blocks to handle exceptions effectively and ensure the proper functioning and stability of a program.

System clocks and bus clocks are two types of clocks in a computer system. A system clock is a central clock that controls the timing of all the operations in the system.

It sets the pace for the CPU, memory, and other components. The system clock is generated by a crystal oscillator on the motherboard and it determines the speed at which the CPU executes instructions. On the other hand, bus clocks are responsible for controlling the timing of data transfer between different components of the computer system. The bus clock is usually slower than the system clock, but its frequency is still a significant factor in determining the overall performance of the system. The bus clock is generated by the chipset on the motherboard and it determines the speed at which data is transferred between the CPU, memory, and other components. In summary, the main difference between system clocks and bus clocks is that system clocks control the timing of all operations in the system, while bus clocks control the timing of data transfer between different components of the system. System clocks are faster and more crucial for overall system performance, while bus clocks are slower but still play an important role in system efficiency.

The layer that manages the transmission of data across a physical link and is primarily concerned with physical addressing and the ordered delivery of frames is the Data Link Layer.

The Data Link Layer is the second layer of the OSI (Open Systems Interconnection) model, which is a conceptual framework for understanding the functions of a communication system. The Data Link Layer is responsible for establishing and maintaining a reliable link between two nodes in a network.

The Data Link Layer is concerned with two main functions:

Framing: The Data Link Layer takes the packets from the Network Layer and divides them into smaller, more manageable units called frames.

Each frame is then given a unique physical address, known as a MAC (Media Access Control) address. The MAC address is used to identify the source and destination of the frame.

Error Control: The Data Link Layer ensures that the frames are transmitted without errors by providing error detection and correction mechanisms.

If an error is detected, the Data Link Layer requests the retransmission of the frame.

The Data Link Layer also provides flow control, which is the process of regulating the rate of data transmission to prevent the receiver from being overwhelmed with too much data.

This is accomplished using techniques such as buffering and congestion control.

Overall, the Data Link Layer plays a crucial role in ensuring the reliable transmission of data across a physical link in a network.
