b) Write a program to update the rate by increasing 10% from a sequential data file "Data.dat" that store item name, rate and quantity​

Answers

Answer 1

The update program is an illustration of the file manipulation processes, where files are read and updated

How to write the program?

The program written in QBASIC, where comments are used to explain each line is as follows:

REM This opens a new file for output

OPEN "NEW.DAT" FOR OUTPUT AS #2

REM This is repeated until the end of the file

WHILE NOT EOF(1)

   REM This inputs the item details

   INPUT #1, N$, R, Q

   REM This updates the rate by 10%

   NEWRATE = R + 10 / 100 * R

   REM This writes the inputs to the file

   WRITE #2, N$, NEWRATE, Q

WEND

REM This closes the files

CLOSE #1, #2

REM This deletes the Data.dat file

KILL "DATA.DAT"

REM This renames the NEW.DAT to the Data.dat file

NAME "TEMP.DAT" AS "DATA.DAT"

REM The program ends here

END

A processor accesses main memory with an average access time of T2. A smaller cache memory is interposed between the processor and main memory. The cache has a significantly faster access time of T1

Answers

For any single memory access, the theoretical speedup to access a word stored in the cache rather than in main memory is given by:

[tex]Speedup=\frac{T_2}{T_1}[/tex]

Given the following data:

Access time = [tex]T_1 < T_2[/tex]

What is cache?

Cache can be defined as a random access memory (RAM) that is used by the central processing unit (CPU) of a computer system to minimize (reduce) the average time taken to access memory (AMAT).

For any single memory access, the theoretical speedup that would be used by the processor to access a word stored in the cache rather than in main memory is given by:

[tex]Speedup=\frac{T_2}{T_1}[/tex]

Where:

[tex]T_2[/tex] is the time to access in main memory.[tex]T_1[/tex] is the time to access in cache.

How to define input in Python?

In Python, we do this using the input() function, which is literally 'input' in English. The input() function receives as a parameter a string that will be shown as an aid to the user, usually informing him what kind of data the program is expecting to receive.

So in an easier way we have that the code is:

def isNumber(x):

   if type(x) == int:

        return True

   else:

        return False

input1 = 122

input2 = '122'

if isNumber(input1):

   print("Integer")

else:

   print("String")

if isNumber(input2):

   print("Integer")

Suppose that you have a computer with a memory unit of 24 bits per word. In this
computer, the assembly program’s instruction set consists of 198 different operations.
All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory.
1. How many bits are needed for the opcode?
2. How many bits are left for the address part of the instruction?
3. How many additional instructions could be added to this instruction set without
exceeding the assigned number of bits? Discuss and show your calculations.
4. What is the largest unsigned binary number that the address can hold?

Answers

Answer:

a )   The amount of bits required for the opcode

 8 bits

2^8=  256        

 256>198

 We get the next lower number, which is 2^7 = 128 bits, because it is greater than 198. As a result, the operation code necessitates 8 bits.

b)   The number of bits reserved for the instruction's address.

 16 bits

 24-8  =  16

c)  

 65536

2^16  =  65536

 Maximum number =  65535

  2^15 = 32768-1

 =  32767
