True, A system's DMA engine is a unique component that manages transfers between hardware and main memory with minimal CPU involvement.
Memory is a system or device used in computing to store data for immediate use in a computer, associated computer hardware, or digital electronic devices. Primary storage and main memory are frequently used interchangeably when referring to one another. The store is a dated word that describes memory.
Compared to storage, which is slower but cheaper and has a bigger capacity, computer memory functions at a high speed. Computer memory also acts as a disc cache and write buffer to speed up reading and writing in addition to storing opened programs. Operating systems use RAM that is not being used by running programs for caching. The computer memory's contents can be moved to the storage if necessary; this is a frequent method.

if 8 mhz clock is used as the system clock and the systick selects it as the clock, what should the systick load register be in order to generate a systick interrupt every microsecond?
To generate a systick interrupt every microsecond with an 8 MHz clock, the systick load register should be set to 7999. A systick interrupt is a type of interrupt that is generated by the systick timer, which is a timer that is built into many microcontroller systems.
The systick timer is typically used to generate periodic interrupts, which can be used to trigger events or tasks at regular intervals. The frequency at which the systick interrupt is generated is determined by the value that is loaded into the systick load register, and the systick interrupt can be used for a variety of purposes, such as maintaining a real-time clock, implementing timeouts, or managing the scheduling of tasks.
In order to generate a systick interrupt every microsecond with an 8 MHz clock, the systick load register would need to be set to 7999. This is because the systick timer counts down from the value that is loaded into the systick load register, and 8 MHz is equal to 8,000,000 cycles per second.
Therefore, to generate a systick interrupt every microsecond, the systick load register would need to be set to 8,000,000 / 1,000 = 7999.

which technique did we discuss in class that has been used to attempt to regrow damaged axons in the cns?
For people who have had a spinal cord injury or stroke, persistent deficits result from the adult CNS axons' inability to regenerate.
The inability of damaged axons to repair and recreate functional connections with their original targets leads to permanent impairments after CNS injury. In contrast, peripheral nerve damage is followed by a powerful regeneration process, which may result in the restoration of sensory and motor abilities. This healing response necessitates the extensive activation of epigenetic and transcriptional alterations in damaged neurons. Understanding how peripheral axon damage causes these pervasive changes through the coordinated actions of transcription factors, epigenetic modifiers, and, to a lesser extent, microRNAs, has advanced significantly in recent years. These new findings provide light on the critical function of coordinated gene expression and chromatin remodelling in the neuronal response to damage, even if many concerns remain about the interaction between these systems.

hat is the average i/o time to transfer a 16kb block on a 4800 rpm disk with a 5ms average seek time, 2gb/sec transfer rate with a .2ms controller overhead? (write up to two decimal places)
The rotational delay and transfer time are partially determined by rotational speed, expressed in revolutions per minute (RPM). Typically, manufacturers report seek times of 8 to 10 ms.
Hard drives are often restricted to a transfer rate of between 100 MBps and 200 MBps because of how they operate—with rotating discs—and how they store and access data. Data is transferred from the disk over a period of time, or "transfer time." The speed of the disk's spinning affects it. The number of bytes on a single track is also referred to as the disk density, and the more quickly a disk rotates, the faster we can read data from it. Lower transfer times result from faster data transfer.

A subclass is a class that is descended from another class (also a derived class, extended class, or child class). A superclass is the class from which a subclass is descended (also a base class or a parent class).
All classes, including the ones you create, share behavior that is specified and implemented by the Object class, which is found in the java.lang package. A hierarchy of classes is formed in the Java platform by the fact that many classes descend directly from Object, others derive from some of those classes, and so on.
The private members of a parent class are not inherited by a subclass. However, the subclass may also use the public or protected methods that the superclass provides to access its private fields.
A nested class gets access to all the properties and methods that are private to its parent class. As a result, a subclass inheriting a public or protected nested class gets indirect access to every private member of the superclass.
