int my variable; <- not a valid declaration

Java naming conventions say that you should use capital letters to differentiate words in a variable name.

int myVariable; <- valid!

Note that you can use the _ (underscore) character, as well, though some people suggest avoiding this.

int my_variable; <- also valid!

A data Sublanguage is a computer language used to define or manipulate the structure of a relational database management system(DBMS) e.g QBE, SQL.

ping -n 8 destination

for each pixel in image

pixel.red = 255 - pixel.red

pixel.green = 255 - pixel.green

pixel.blue = 255 - pixel.blue

The reason why you might not find differences in the sdlc and rad is because RAD is a more sped-up version of the SDLC. RAD is typically used in small to medium size projects, while the SDLC is generally used for large projects. Another difference is that in the SDLC, one can control the scope creep of the project, whereas that is very limited when one implements RAD because you give it up for faster implementation times. In RAD you have alot of feedback from the user to refine the program more to the aspects of the user, whereas you dont get the same user input in the SDLC. This feedback loop is another reason that RAD is sometimes chosen over the SDLC

The given expression would be-

F(A,B,C,D)=E(0,2,4,5,6)

where E=Summation

F= Function

A,B,C,D represents binary variables,

Now, for solving this problem, we draw a map with 2m cubes, since here is only 4 binary variables it will be 24 cubes means 16 boxes.

Each row will contain 4 boxes, the numbering of boxes is very important for the solution of the problem,

Numbering for the first block will be- 0,1,3,2

Numbering for the second block will be- 4,5,7,6

Numbering for the third block will be- 12,13,15,14

Numbering for the fourth block will be- 8,9,11,10

The left most and the upper most parts are numbered 00,01,11,10 horizontally as well as vertically

Now, place 1 at all the specified boxes(as per the question i,e;E(0,2,4,5,6,))

See the picture below...

Start combining all the adjacent boxes having 1 in it.

Note: all the four corners of the map are adjacent to each other.

Think it as, when you fold the page it will be together.

When trying to combine the boxes we will first look for 16 boxes all together, whether it can be combined or not(It can only be combined if it is filled with 1).

If not, then we will look for 8 boxes together then 4 the 2 at last 1. No box filled with 1 should remain alone. It must be combined with others, we can use same box to combine a non-combined box.

After making all the combinations,

Take anyone of the combination look for it`s rows and column involved in making the combination. take the common variable of column and common variable of row and write it then write + again look for the another combination and repeat the same process for all the combination.

For eg;

From the above example, 2 and 4 can be combined because both are adjacent to each other the value for this combination would be A`CD`.

Try it...

you can download a computer program to minimize k map it is:-

A light bulb and a lens. In combination the form a machine to project an image.

To insert a number N into array A at index I:

// Resize A if necessary

If A is too small to add a new element then

resize A

// Right-shift all elements starting from position I

For i = A.length to I

A[i] = A[i - 1]

// Insert new item

A[I] = N

A real example of parallel execution of sequential programs in a multi-core architecture might be the addition of two matrices...

double a[1000,1000];

double b[1000,1000];

double c[1000,1000];

int i, j;

for (i=0; i<1000; i++) for (j=0; j<1000; j++) c[i,j] = a[i,j] + b[i,j];

...Since each of these 1000000 additions are independent of each other, they could easily be dispatched to multiple threads and run on multiple cores...

for (i1=0; i1<1000; i1+=4) for (j1=0; j1<1000; j1+=4) c[i1,j1] = a[i1,j1] + b[i1,j1];

for (i2=1; i2<1000; i2+=4) for (j2=0; j2<1000; j2+=4) c[i2,j2] = a[i2,j2] + b[i2,j2];

for (i3=2; i3<1000; i3+=4) for (j3=0; j3<1000; j3+=4) c[i3,j3] = a[i3,j3] + b[i3,j3];

for (i4=3; i4<1000; i4+=4) for (j4=0; j4<1000; j4+=4) c[i4,j4] = a[i4,j4] + b[i4,j4];

...with each for loop running in its own thread/core. In fact, most modern optimizing compilers, at the higher optimzation levels, is quite capable of doing this on its own, because they analyze the code and break apart things that can run in different threads automatically.

literals are used to store constant values which are not changed even after program execution

Has your computer been dragging as of late? All of a sudden you can't access certain files or programs - your system keeps crashing. If so, you just may have a malicious program controlling the system from the internal sectors of your computer - you just may have contracted a boot infector, a virus that has compromised thousands of computers.

It depends on the processor. In the 8086/8088, it means

MOV AX,[BX+SI]

LODSB

In the 8085 it means

ADC E

NOP

XRA H

Neither snippet makes any sense, so it must be from some other processor.

IRQ, DMA Channel, I/O Addresses, Memory Addresses

The instruction represented by this code depends entirely on the architecture that you are trying to translate it for.

Well, whatever you do, you'll have to learn. The easiest way to learn some basics is to use a high level programming language such as, Perl, PHP, Ruby, Python etc.. (very long list).

The concept of layers help in reducing the size of transistors. .Every year transistors' number go on increasing in a microprocessor chip. Where does this increase come from?it comes- Chips gets larger and the transistors get more and more smaller. Transistors shrink in size because of their ability to control photo lithography and the technology of process advances.

if the link is invalid wait for sometime like 4-5 hours i have just added it and it will take time to publish

it depends on the software written for the computer its the software that controls the outcome the hardware just processes it
