Computer Programming

Advantages

- more human-understandable, logical and easy-to-learn syntax that enables programmer to code more effectively

- portability - some of them can be hardware and OS indipendent, for example Java

Disadvantages

- they are usually slower than lower-lever languages, for example assembler is faster than C which is faster than C++ which is faster than c# or Java (on the same computer, of course)

Top down marketing is a branding strategy where country strategies are based upon global branding strategies.

Some advantages of the internet are being able to job search for one. Also being able to research for school, or even looking up a recipe. Keeping in touch with E mail and Shopping online, or even online dating!

They are 2 different things, not compatible in nature.

However, you can have a project to have iOS, Windows, Linux, etc all running under your new open source operating system, then the answer may be yes.

Windows, from the other hand, never have open source in mind, so itself is definitely not going to have features compatible to open source. (if there is any, it is accidental, and Microsoft may take that away in the future)

char* new_string; // could be any type

new_string = (char*) malloc (5120); // allocate memory - typecast is necessary

if (new_string == NULL) ... memory exception ...

... use the data ...

free (new_string); // release memory when done

All websites use HTML, but some sites use HTML in conjunction with one or more other coding languages like Javascript or CSS. HTML-only means it uses just the basic coding.

A modem, short for modulator/ demodulator, "packages" data that is being transmitted so it fits whichever transfer protocol it's working with. That includes chopping up the data to the proper packet sizes, adding error-checking bits and addressing info, etc. It also does the opposite with received data, "unpacking" it so your computer can work with it.

They both are same. Both of them mean a set of instructions. but, an algorithm is a simple flow of instructions whereas in a flowchart the instructions are represented pictorially, and as the name suggest it is a 'flow chart'.

Java (an Indonesian island). However, the Java programming language was named after the Indonesian coffee bean (a favourite of one of its developers) rather than the island itself.

AND OR NOT

In a google search, the AND is implied, the OR is explicit, like (iceberg OR glacier),

and the NOT is expressed with a '-' before the relevant term.

EZtrieve and EZtrieve Plus are examples of a high level language that can be either compiled or run interpretive.

Autoethnography is a reflexive perspective on the self as researcher. A text is written in the research process, on the researcher's experience, which can be called an autoethnographic text. This is sometimes referred to as reflexive ethnography.

Data warehouse is the database on which we apply data mining.

A pointer variable is a variable that contains the memory location of another variable or an array (or anything else in memory). Effectively, it points to another memory location.

For standard variables, you define a type, assign a value to that variable or read the value from it, and you can also read the memory location (&n = memory location of n) of the variable.

For pointers, you can point them to any variable, even another pointer, and you can get the value of the variable it points to (*p), the location of that variable in memory (p), or the address in memory of the pointer itself (&p).

Consider:

long n = 65;

long *p;

p = &n;

Results:

Type | Name | Location | Value

long n 0xA3FF 65

long * p 0x31DF 0xA3FF

So p points to n. Now,

n = 65

&n = 0xA3FF

p = 0xA3FF

*p = 65

&p = 0x31DF

You may find yourself having to use typecasts frequently when using pointers.

Pointers are useful when passing data to functions.

For instance, consider the following function:

void add(int a, int b, int c) { c = a + b; }

The problem here is that the computer copies each variable into a new memory location before passing them to the function as local variables. This function effectively does nothing. However, if you change the function to:

void add(int a, int b, int *c) { c = a + b; }

and call the function by passing in the location of the variable to the function:

add(a,b,&c);

then you can modify the variable itself.

Pointers are also good for working with arrays:

char *c = "Hello World";

int i=0;

while (c[i] != 0x00) { cout << c[i]; c++ } //print one letter at a time.

The for loop is used when you want to do a procedure, a certain amount of times.

The for loop is used when you already know how many times the loop will be repeated.

for example... you want to scan an array.

you can do something like this.

for(i=0;i<myArray.length;i++){

if(myArray[i] == 5){

alert("This array position contains the number five.");

}

}

the code above is javascript.

But the idea is the same in any language.

This is one use, but as I said. You use it when you already know the amount of times the loop will be repeated.

It depends on the encoding but if we assume standard ASCII encodings, the representation is the same for all systems, the only difference being the number of leading 0 bits per character.

7-bit ASCII (ISO/IEC 646):

1100100 1100001 1100100 1100100 1111001 0000000

8-bit ASCII (ISO/IEC 8859, Windows-1252 and UTF8):

01100100 01100001 01100100 01100100 01111001 00000000

UTF16:

00000000 01100100 00000000 01100001 00000000 01100100

00000000 01100100 00000000 01111001 00000000 00000000

To perform these conversions, convert each character to its ASCII representation (in decimal):

d = 100

a = 97

d = 100

d = 100

y = 121

For completeness, we should also include the null-terminator, character code 0.

null = 0

Now convert each decimal value to its 8-bit representation in hexadecimal:

100 = 0x64

97 = 0x61

100 = 0x64

100 = 0x64

121 = 0x79

0 = 0x00

Convert each hexadecimal digit to its 4-bit binary representation:

0x6 = 0110

0x4 = 0100

0x6 = 0110

0x1 = 0001

0x6 = 0110

0x4 = 0100

0x6 = 0110

0x4 = 0100

0x7 = 0111

0x9 = 1001

0x0 = 0000

0x0 = 0000

Place the binary codes in sequence.

"daddy" = 01100100 01100001 01100100 01100100 01111001 00000000

Finally, add or remove leading zero bits to suit the actual encoding.

"Linking" refers to providing a "reference" to the source data; if the source is deleted, the link no longer functions; many different types of files, programs, and programming interfaces refer to displaying externally located data as linking. Linking is advantageous when the data might later change and the program or file that contains the link would benefit from having the latest version of the data.

"Embedding" has a slightly different context depending on the context that you are using it. If you are referring to a file (such as a Flash file, Microsoft executable file, and so on), embedding refers to storing the data directly within the other data type. An executable can store Icon files, for example, which alter their presentation on the Desktop or Start Menu by showing an identifying image so users can tell programs apart visually. Embedding in a document file depends on the type of document file in question. Some document files store a copy of the data in the file, while other document formats simply imply that a plugin program is embedded into the document's data. Finally, applications can embed other applications within them during execution. For example, a program could be written to embed an Internet Explorer web viewer into a larger program.

When embedding refers to "storing a copy", the benefit is that the source file can be deleted without affecting this dependent file. The disadvantage, of course, is that updates to the source data require updating the dependent file through whatever means available (applications have to be recompiled, documents have to be edited, etc).

When embedding refers to "running a copy of a program within another program", there are many advantages: less code has to be used each time a component is reused, the component can be upgraded independently of the main program, and a component can crash without crashing the entire application (possibly including recovering data from the failed component). The disadvantage of embedding is, of course, memory usage will be higher than having a single, unified program.
