You have n warehouses and n shops. At each warehouse, a truck is loaded with enough goods to supply one shop. There are m roads, each going from a warehouse to a shop, and driving along the ith road takes d i hours, where d i is an integer. Design a polynomial time algorithm to send the trucks to the shops, minimising the time until all shops are supplied.

Answers

Following are the steps of the polynomial-time algorithm:

Split the routes according to their categorizationAssuming that mid = di of the middle road, low = road with the least di, and high = road with the highest di, we may do a binary search on the sorted list.All shops must be approachable only using these roads for every road, from low to mid.Check if all shops can be reached from[tex]\bold{ low \ to\ mid+1}[/tex] using only these roads.There is a solution if every shop can be reached by road only up to [tex]\bold{mid+1}[/tex], but not up to mid.You can [tex]\bold{set \ low = mid+1}[/tex] if all businesses aren't accessible using both [tex]\bold{mid\ and\ mid+1}[/tex] roads.If every shop could be reached using both mid and mid+1, then set high to mid-1.With these layouts of businesses and roads, no response can be given because [tex]\bold{ low > high}[/tex]You can do this by [tex]\bold{set\ mid = \frac{(low + high)}{2}}[/tex]The new low, mid, and high numbers are used in step (a).

In a minimum amount of time, this algorithm will determine the best strategy to supply all shops.

Give examples of applications that access files by each of the following methods:
+ Sequentially.
+ Random.

Answers

Answer:

Explanation:

Usually, applications would have the capability of using either one of these options. But for the sake of the question here are some that usually prefer one method over the other.

Any program that targets an API usually uses Sequential access. This is because API's contain all of the data as objects. Therefore, you need to access that object and sequentially navigate that object to the desired information in order to access the data required.

A music application would have access to an entire folder of music. If the user chooses to set the application to randomly play music from that folder, then the application will use a Random Access method to randomly choose the music file to load every time that a song finishes.

c. Subnet masks are used with both class and classless IP addresses.
d. all statements are correct.

Answers

Yeah the answer is b

Subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.

What is an IP address?

A device on the internet or a local network may be identified by its IP address, which is a special address. The rules defining the format of data delivered over the internet or a local network are known as “Internet Protocol,” or IP.

Only C is correct, rest other statements are incorrect because:

a. IPv4 and IPv6 addressing is fully compatible with one another is incorrect. While IPv4 and IPv6 can coexist on the same network, they are not fully compatible with one another.

b. CIDR address format represents a Class C network only used within an intranet is incorrect. Classless Inter-Domain Routing (CIDR) is a technique used to allocate IP addresses more efficiently.

Therefore, subnet masks are used with both class and classless IP addresses is the correct statement. Therefore, the correct option is C.

I connected to an external hard drive to transfer some photos from my vacation. When I try to drag the photo, it bounces right back and does not transfer. What is the likely cause of this issue?

a. hard drive is full

b. photos were taken in a different country

c. USB port is broken

d. the file structure of the 2 hard drives are not compatible

Answers

Your answer is D.

Hope this helps and if you could answer the question I just uploaded titled giving brainliest that would be great. Basically, what you have to do is research why the book titled the list of things that will not change and explain why it’s your favorite book based on the message it tells you! Go to my profile and go to questions.

The answer is D, What is the likely cause of this issue is that the file structure of the two hard drives are not compatible.

The file structure or file system, of a hard drive, tells the disk how to read, write and store information on the drive. Some file systems do not allow the disk to store any files and often do not display error messages. If we try to drag a file onto a hard drive with this kind of file structure, the action would simply not be performed. This can be fixed by formatting the disk partition into a new file system.

Option B states that the issue may be that the photos were taken in a different country. This is not the cause of the problem because regardless of where the pictures are taken, they are all stored in common formats such as:

JPEGPNGJFIF

Any external hard drive capable of storing images will have the ability to receive files in these formats as well as many other image formats. For this reason, option B is False.

The question states that you were able to connect the external Hard drive and drag files onto it, though unsuccessfully. This tells us that the USB port is working as intended, if it were not working, it would not display the Hard drive onto the computer and we would not be able to drag files to it. Therefore, option C is false

Insufficient Hard drive storage space is a common issue in not being able to transfer files between hard drives. However, if this were the case, the user would be shown a message displaying the error. The message may look like:

"Insufficient space on the disk.""The Disk is full.""Not enough memory to complete this action"

The exact wording may vary depending on the operating system in use. Since the question states that the files simply "bounces back" without an error message displaying, we can infer that option A is false.

Discuss the DMA process​

Answers

Answer:

Direct memory access (DMA) is a process that allows an input/output (I/O) device to send or receive data directly to or from the main memory, bypassing the CPU to speed up memory operations and this process is managed by a chip known as a DMA controller (DMAC).

Explanation:

A defined portion of memory is used to send data directly from a peripheral to the motherboard without involving the microprocessor, so that the process does not interfere with overall computer operation.

In older computers, four DMA channels were numbered 0, 1, 2 and 3. When the 16-bit industry standard architecture (ISA) expansion bus was introduced, channels 5, 6 and 7 were added.

ISA was a computer bus standard for IBM-compatible computers, allowing a device to initiate transactions (bus mastering) at a quicker speed. The ISA DMA controller has 8 DMA channels, each one of which associated with a 16-bit address and count registers.

ISA has since been replaced by accelerated graphics port (AGP) and peripheral component interconnect (PCI) expansion cards, which are much faster. Each DMA transfers approximately 2 MB of data per second.

A computer's system resource tools are used for communication between hardware and software. The four types of system resources are:

   I/O addresses    Memory addresses.    Interrupt request numbers (IRQ).    Direct memory access (DMA) channels.

DMA channels are used to communicate data between the peripheral device and the system memory. All four system resources rely on certain lines on a bus. Some lines on the bus are used for IRQs, some for addresses (the I/O addresses and the memory address) and some for DMA channels.

A DMA channel enables a device to transfer data without exposing the CPU to a work overload. Without the DMA channels, the CPU copies every piece of data using a peripheral bus from the I/O device. Using a peripheral bus occupies the CPU during the read/write process and does not allow other work to be performed until the operation is completed.

With DMA, the CPU can process other tasks while data transfer is being performed. The transfer of data is first initiated by the CPU. The data block can be transferred to and from memory by the DMAC in three ways.

In burst mode, the system bus is released only after the data transfer is completed. In cycle stealing mode, during the transfer of data between the DMA channel and I/O device, the system bus is relinquished for a few clock cycles so that the CPU can perform other tasks. When the data transfer is complete, the CPU receives an interrupt request from the DMA controller. In transparent mode, the DMAC can take charge of the system bus only when it is not required by the processor.

However, using a DMA controller might cause cache coherency problems. The data stored in RAM accessed by the DMA controller may not be updated with the correct cache data if the CPU is using external memory.

Solutions include flushing cache lines before starting outgoing DMA transfers, or performing a cache invalidation on incoming DMA transfers when external writes are signaled to the cache controller.

Answer:

See explanation

Explanation:

DMA [tex]\to[/tex] Direct Memory Access.

The peripherals of a computer system are always in need to communicate with the main memory; it is the duty of the DMA to allow these peripherals to transfer data to and from the memory.

The first step is that the processor starts the DMA controller, then the peripheral is prepared to send or receive the data; lastly, the DMA sends signal when the peripheral is ready to carry out its operation.
