What is the binary code for B?
That depends what you mean by "B", and what you mean by "binary code"
assuming that by "binary code", you actually mean a binary representation of it's ascii value, then the answer is 1000010. The ascii value of the character "B" is 66 in decimal, which is 1000010 is that value in binary.
If on the other hand, you mean "what is the binary value of the hexidecimal number B?", then the answer is 1011.
What is data structure why is an array called a data structure which are the other data structures?
A data structure is a collection of more than one elementary item, in some kind of aggregate organization.
An array is a type of structure where more than one item of the same type are arranged serially in memory, and accessed using an index. The item can either be an elementary type or it itself can be a structure type.
A struct (not to be confused with the use of "structure" in this answer) is a type of structure where more than one item of the same or different types are arranged serially in memory, and accessed using the structure member (.) operator.
A union is similar to a struct, except that each member occupies the same address. This means that only one type of data can be stored at any one time in a union.
A self-referential structure is a type of structure, usually constructed of simpler structures, linked together with some kind of pointer scheme. Examples of this are the linked list and tree.
What can be distinguish between a computer a computer program and an information system?
To answer such question we realy shortly define each one of the 3 definaions appeared in the question: information system: set of interrelated components working together to collect,process,store,and dissementate information to support decission making, coordinate,control,analysis,and visualization in an organization. computer: the instrument consist of physically hardware and need an operating system to be run in such way of input,processing,output of data entered into displayed information computer program: a type of software designed by engineering archtecture helping people to calculate,wrigting,getting suitable quierries and reports from predefined data entered converting them into suitable information. by getting such definations we get the solution through combining such predefination into one simply one named computer-based information systems ( CBIS ) which is an information system that relies on computer hardware ( computer ), software ( programs and applications ) for rocessing and disseminating information
What is operation signature in UML?
Syntax for UML operation is:
operation ::= [ visibility ] signature [ oper-properties ]
Signature of the operation has optional parameter list and return specification.
signature ::= name '(' [ parameter-list ] ')' [ return-spec ]
Name is the name of the operation. Parameter-list is a list of parameters of the operation in the following format:
parameter-list ::= parameter [ ',' parameter ]*
parameter ::= [ direction ] parm-name ':' type-expression [ '[' multiplicity ']' ] [ '=' default ] [ parm-properties ]
See details and examples in the provided link.
Before you can start working on ranking for a keyword, you need to know the competition for that keyword. This tool not only helps you determine how many people are ranking for your target keyword but also tells you how difficult it can be to rank it cutt.ly/qjyTwV2
Difference between loop and array?
A loop usually referred to the program flow control with possible repetition of executing the same codes, an array is an abstraction of fixed size container. 2 different concepts.
Do you need hackers and crackers?
Yes. We need white-hat hackers to help us defend against black-hat hackers (crackers). Unfortunately, many white-hat hackers are themselves former black-hat hackers, it goes with the territory. Not all of them, granted, but if you want to test your house security, who better to test it than a former burglar!
Programming software offers tools for developers of all levels to create, debug and maintain various programs and applications.
Difference between boundary fill algorithm and scanline polygon fill algorithm?
in scan line polygon fill, each can line crossing a polygon, the area fill algorithm locates the intersection point of the scan line with the polygon edges. These intersection points are then stored from left to right and the corresponding frame buffer positions between each intersection painr are set to the specified fill color.
In boundary fill, approach to area filling is to start at a point inside a region and paint the interior outward toward and the boundary.
What is the role of algorithm in problem solving?
the concept of problem solving problems in algorithms are problem solving in computer, what is the algorithms for solving in problems, what is the rule o algorithms in problem solving, what are the steps to solving a problem with your computer and engineering steps for solving problems
What tool used to convert C++ source code into executable machine code?
Compliers are used to convert C++ into assembly code. Then a tool called an "assembler" converts that code into machine code. Finally, a "linker" connects all of those machine code files into a single executable.
What is the difference between global and extern?
Global variables and extern variables are very similar, but with a major difference. Let's say you have a global variable in your header file, like this:
( Refer how u can add the variable declaration in the source code as extern, i think we cant add into header files as it said)
int x = 0;
Now, in each file that includes that header file, there will be a new variable called x. Modifying x in file1.cpp won't modify x in file2.cpp.
Now, for externs... Say you have something like this in your header:
extern int x;
Then, in file1.cpp (which includes your header):
int x = 0;
Then, in file2.cpp (also includes the header):
x = 46;
x in file1.cpp is also now equal to 46. You see, when you use an extern variable, you're telling the compiler that you want to use that variable across all of your source files. If you use a regular global, however, you create a new variable in each of your source files.
Anyway, that's just for variables, which I assume you're talking about - global and extern functions are a bit different, and I'm not entirely clear on them.
What is the half split fault location technique?
half split technique is a fault finding method in which faulty area is compared with one of the similar working area. in hydraulic rig, say if cylinder B is not working, we compare it against another working cylinder, say cylinder A. By comparing we collect data and determine the difference between both working and non working components.
i.e. what is the status of incoming and out going flow in both (working and non working) components?
are both pressurized only when it should?
etc.

What type of software is Microsoft PowerPoint?
Microsoft PowerPoint is an applications software. It is a presentations software application. It has been designed to create electronic presentations which consist of a number of pages or slides. The software also includes several templates to make designing a slideshow a quick and easy process.

What does a computer process contains?
Processes are an operating system concept used to allow multiple programs to appear to run simultaneously on one computer. The operating system allocates at least one process to every program and switches periodically from running one process to another process.
As a process is a concept, not a physical object, it does not actually contain anything.
1)Time taken to error correcting is less than doing detection and retransmission.
Bandwidth use will be less.
2) In detection and retransmission if back messaging occurs the bandwidth will be more
