Answer:

The enormous amount of data and information that a company generates and consumes today can become an organizational and logistical nightmare. Storing data, integrating it and protecting it, so that it can be accessed in a fluid, fast and remote way, is one of the fundamental pillars for the successful management of any company, both for productive reasons and for being able to manage and give an effective response to the customers.

Good big data management is key to compete in a globalized market. With employees, suppliers and customers physically spread across different cities and countries, the better the data is handled in an organization, the greater its ability to react to market demand and its competitors.

Databases are nowadays an indispensable pillar to manage all the information handled by an organization that wants to be competitive. However, at a certain point of development in a company, when growth is sustained and the objective is expansion, the doubt faced by many managers and system administrators is whether they should continue to use a database system, or if they should consider the leap to a data warehouse. When is the right time to move from one data storage system to another?

Answer:

The program in Python is as follows:

cents = int(input("Cents: "))

qtr = int(cents/25)

cents = cents - qtr * 25

dms = int(cents/10)

cents = cents - dms * 10

nkl = int(cents/5)

pny = cents - nkl * 5

print("Pennies: ",pny)

print("Nickels: ",nkl)

print("Dimes: ",dms)

print("Quarters: ",qtr)

Explanation:

The program in Python is as follows:

cents = int(input("Cents: "))

This calculate the number of quarters

qtr = int(cents/25)

This gets the remaining cents

cents = cents - qtr * 25

This calculates the number of dimes

dms = int(cents/10)

This gets the remaining cents

cents = cents - dms * 10

This calculates the number of nickels

nkl = int(cents/5)

This calculates the number of pennies

pny = cents - nkl * 5

The next 4 lines print the required output

print("Pennies: ",pny)

print("Nickels: ",nkl)

print("Dimes: ",dms)

print("Quarters: ",qtr)

I think you want to convert binary to hex.

Hexadecimal or "hex" is a numbering system which uses 16 different numerals. We saw that decimal used ten numerals from 0 to 9. Hex expands on this by adding six more, the capital letters A, B, C, D, E and F.

0...1...2...3...4...5...6...7...8...9...A...B...C...D...E...F

Steps to Convert Binary to Hex

1. Start from the least significant bit (LSB) at the right of the binary number and divide it up into groups of 4 digits. (4 digital bits is called a "nibble").

2.Convert each group of 4 binary digits to its equivalent

hex value .

3.Concatenate the results together, giving the total hex number.

Excel will generally be able to handle any properly-input mathematical formula, if valid operators are used. Commonly used operators include "+" (addition), "-" (subtraction), "*" (multiplication) and "/" (division).  (Microsoft has a complete list of valid operators to be used in Excel formulas on the Office website).  Here are some examples of formulas using common operators:

Formula                                                                              Description

=C2-B2                                                                Subtracts contents of B2 from contents of C2

=C2/B2                                                                Divides contents of C2 by contents of B2

=(B2+C2+D2)/3                                                  Adds contents of B2, C2, and D2 and divides result by 3

After hitting "Enter", the cell will display the calculated value, while the formula bar will still display the formula.  (Note: Always hit “Enter” when finished entering a formula, manually.  If you click off the cell, the cell you click to will be added to your formula.)Formulas

Formulas in Excel are basically mathematical expressions that use cell references (e.g., “A5”,” D17”) as arguments.  For example, a formula that adds the contents of cell E5 and E6 could be written as follows:

= E5+E6

(Note: all formulas in Excel need to be preceded by an “=” sign.) If the values contained in E5 and E6 are 6 and 11, respectively, the formula will produce 17 as the value it displays. If you change E5 to 7, the result will automatically change to 18.

Example

Let's say you were putting together an office supply order, and you wanted to keep track of much you were spending. You could put together a spreadsheet like the one below, with the list of items to be purchased, their unit prices, the number of each item ordered, and the total spent for each.  It would make sense to enter the things you know in advance (like the price of individual items and the number ordered), but you could let Excel calculate the totals for you.  For the first item listed below (pencils), this could be done by making the value of the total price (cell D2), the value of the unit price (held in cell C2) multiplied by the number of items ordered (held in D2).  This formula would be written "=B2*C2".

Once you click "OK", your completed formula will be input into the cell.

Copying and pasting formulas

Often, you will need Excel to do a series of similar computations, where the only things that will change are the cells used as arguments.  For instance, in the example above, you would probably like Excel to calculate the Total Price for each item in the order.  You could re-input the same formula used to get the total price for pencils in each cell in that row, just changing the cells referenced (i.e. "=PRODUCT(B3:C3)", "=PRODUCT(B4:C4)", etc.), but Excel has simpler method for this. If you have multiple cells in the same row or column that need to do the same computation, you can simply copy the value in the cell you entered a formula, and then paste it into the subsequent cells.  Excel will then automatically adjust which cells are included in the formula, based upon which cell the formula was pasted to.  So, if the original formula entered in D2 was "=PRODUCT(B2:C2)", the formula pasted into D4 would be "=PRODUCT(B4:C4)"

More simply, if you have a formula you want repeated in a number of directly adjoining cells, you can just click and drag the bottom right corner of the cell with the original formula (see image below) onto the cells you want the same formula entered, and Excel will automatically copy and paste the formula for you, with appropriate adjustments made to the cell numbers in the formula.

After selecting "PRODUCT" and clicking OK, you will get another dialog box, that allows you to select the cells to be multiplied.  You can do this for individual cells, by selecting cells separately in the "Number1" and  "Number2" boxes shown below, or by selecting an array of cells, by clicking and dragging on the range cells you want to use on the spreadsheet, itself.  (Note: if you try to enter a formula in a cell using the Insert Formula button and there are adjacent cells with numbers, Excel will often select those cells automatically, so make sure the cells selected in the dialog box are the correct ones.) Excel also has built-in functions that can do a lot of useful calculations.  These are most easily accessed by hitting the Insert Function button, which is represented by the “fx” symbol next to the formula bar.  For example, instead of entering the formula shown above, the same result could have been achieved using the built-in "PRODUCT" function by clicking in cell D2 and hitting the Insert Formula button.  This would give a dialog box like the one shown, below.

After choosing “PRODUCT” and pressing OK, a new dialogue box will appear where you may choose which cells should be multiplied. By selecting particular cells in the “Number1” and “Number2” boxes as shown below, you can do this for specific cells.

Additionally, Excel contains many useful built-in functions that can perform calculations. The button shown by the “fx” sign next to the formula bar, “Insert Function,” can be used to access these the simplest way by clicking it.

Make sure the cells selected in the dialogue box are the proper ones because if you try to insert a formula in a cell using the Insert Formula button and there are adjacent cells containing numbers. Excel will frequently select those cells automatically.)

Therefore, by deciding a range of cells on the spreadsheet itself by clicking and dragging on the desired range of cells.

Answer:

Explanation:

Threads allow an applications to run faster because they allow various tasks to run at the same time instead of doing one at a time and having to wait for one to finish before starting the next task. However, if too many threads are running at the same time, or a thread has a very large task or requires another task to finish before finishing its own then this can drastically impact performance. Mainly because too many resources are being used at a single moment. The following code is a small example of how threads work in Python.

import threading

import time

def thread_function(name):

   print("Thread {name}: starting")

   time.sleep(2)

   print("Thread {name}: finishing")

thread1 = threading.Thread(target=thread_function, args=(1,))

thread1.start()

time.sleep(1)

thread2 = threading.Thread(target=thread_function, args=(2,))

thread2.start()

thread2.join()

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:

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.

Explanation:

An information system (IS) can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.

Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.

Additionally, an information system comprises of five (5) main components;

1. Hardware.

2. Software.

3. Database.

4. Human resources.

5. Telecommunications.

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

On a related note, the software application that executes the critical functions of an information system (IS) are contained in its operating system (OS).

Basically, the computer's memory, processes, softwares and hardwares are typically being managed by the operating system (OS). Thus, an OS makes it possible for different programs to run simultaneously (more than one software program running concurrently) and access the computer's memory, central processing unit (CPU), and storage.
