Answer:

Answer is explained below

Explanation:

Data: Data are raw facts and figures that are collected together for analysis. In other words, Simple no processing is data.

Information: Information is the facts provided about something. In simple terms, processed data is information.

Knowledge: Knowledge is the processed facts that are understand for a conclusion.

1. An item's UPC number - data

Explanation: An item number is data because simple no processing is required.

2. Change back to customer - information

Explanation: Data about a customer is information.

3. General changes to demand in different seasons - knowledge

Explanation: Requires data (time and quantity purchased) to be processed/aggregated into information. The information is understood to provide a pattern of demad changes due to seasons.

4. Cost each - data

Explanation: Cost each is data because simple no processing is required.

5. Quantity purchased - data

Explanation: Cost each is data because simple no processing is required.

6. Non-taxable total - information

Explanation: -- requires that data (prices, amounts and whether the item is taxable) to be processed (price * amount for items that are non-taxable).

7. Extended cost [quantity times cost each] - information

Explanation: Extended cost requires processing two pieces of data quantity and cost

8. Amount tendered - data

Explanation: Amount tendered is data because simple no processing is required.

9. Sales of an item for the last week - information

Explanation: Sales of an item for the last week requires aggregating sales for a specific time frame together

10. Upcoming holidays and customer's special needs - knowledge

Explanation: Upcoming holidays and customer's special needs requires holiday data (dates) to be combined with information gathered about customer to understand customer's special needs

11. How paid [cash, charge card, debit card] - data

Explanation: Cost each is data because simple no processing is required.

12. Shopper loyalty card number - data

Explanation: Cost each is data because simple no processing is required.

13. Taxable total - information

Explanation: Taxable total requires that data (prices, amounts and whether the item is taxable) to be processed (price * amount for items that are taxable).

For the (pseudo) assembly code below, replace X, Y, P, and Q with the smallest set of instructions to save/restore values on the
Dimas [21]

Answer:

Explanation:

Let us first consider the procedure procA; the caller in the example given.

  Some results: $s0,$s1,$s2, $t0,$t1 and $t2 are being stored by procA. Out of these registers, few registers are accessing by procA after a call to procB. But, procB might over-write these registers.

       Thus, procA need to save some registers into stack first before calling procB, .

      only $s1,$t0 and $t1 are being used after return from procB in the given example,

       Caller saves and restores only values in $t0-$t9, according to MIPS guidelines for caller-saved and callee-saved registers, .

       Thus, procA needs to save only $t0 and $t1.

    jal instruction overwrites the register $ra by writing the address, to which the control should jump back, after completing the instructions of procB, when procB is called,.

       Therefore, procA also need to save $ra into stack.

 ProcA is writing new values into $a0,$a2, procA must save $a0 and $a1 first before calling procB, .

     In the given example, after return from procB, only $a0 is being used. It is therefore enough to save $a0.

   Also, procA needs to save frame pointer, which points the start of the stack space for each procedure.

       Generally, as soon as the procedure begins, frame pointer is set to the current value of the stack pointer,.

Let us consider the procedure procB; the callee in the given example.

 The callee is responsible for saving values in $s0-$s7 and restoring them before returning to caller, this is according to MIPS guidelines for caller-saved and callee-saved registers,

   procB is expected to over-write the registers $s2 and $t0. Nonetheless, in the first two lines, procB might over-write the registers $s0 and $s1.

   Thus, procB is responsible for saving and restoring $s0,$s1 and $s2.

X:

We need to create space for 5 values on the stack since procA needs to save $a0,$ra,$t0,$t1 and $fp(frame pointer), . Each value(word) takes 4 bytes.

$sp = $sp – 20 # on the stack, create space for 5 values

sw $a0, 16($sp) # store the result in $a0 into the memory address

               # indicated by $sp+20

sw $ra, 12($sp) # save the second value on stack

sw $t0, 8($sp) # save the third value on stack

sw $t1, 4($sp) # save the fourth value on stack

sw $fp, 0($sp) #  To the stack pointer, save the frame pointer

$fp = $sp      #  To the stack pointer, set the frame pointer

Y:

lw $fp, 0($sp) #  from stack, start restoring values

lw $t1, 4($sp)

lw $t0, 8($sp)

lw $ra, 12($sp)

lw $a0, 16($sp)

$sp = $sp + 20 # decrease the size of the stack

P:

$sp = $sp – 12 #  for three values, create space on the stack

sw $s0, 0($sp) # save the value in $s0

sw $s1, 0($sp) # save the value in $s1

sw $s2, 0($sp) # save the value in $s2

Q:

lw $s0, 0($sp) #  from the stack, restore the value of $s0

lw $s1, 0($sp) #  from the stack, restore the value of $s1

lw $s2, 0($sp) #  from the stack, restore the value of $s2

$sp = $sp + 12 # decrease the stack size

Answer:

10 20

50 60

Explanation:

Given

The above code segment

Required

What is printed, if anything

To do this, we analyze the code line by line.

Line 1: The first line creates a 4 by 3 array named mat

Line 2: for (int[] row : mat) {  -> This creates row[] array which represents each row of array mat

Line 3: for (int j = 0; j < row.length; j += 2){ -> This iterates through the even indexed elements of the row array i.e. 0 and 2

Line 4: System.out.print(row[i] + " "); -> This prints the even indexed elements of the row array.

The even indexed elements are: 10, 20, 30, 40, 50 and 60

Line 5: System.out.println(); --> This prints a new line

REST Basics REST is a protocol and a set of operations that many web services conform to in order to exchange information and in
vekshin1

Answer:

The answer is "Option A and Option C".

Explanation:

In choice a, it is true since a client-server design can be used for REST-application. A user is somebody who needs space and it doesn't deal with storing data on a central computer. A client is someone with the money, and the interface does not. Its server doesn't want to worry regarding core functionality on the ends of the server. The server does not have to know anything at all about the layer of UI used at the end of the server.

In choice c, it is true As just a Web app, services like corporate/employee resources must be organized, and HTTP verbs like the GET, Place, POST, DELETE must be used to modify these. It must be obvious, as a programmer, that what is required is clearly to look only at the interface or HTTP method used.
