What usually represents one character of data?
A byte (usually 8 bits). An 8-bit byte allows up to 256 unique characters to be represented, more than enough to accommodate all the letters, digits and punctuation marks in the Latin alphabet.
Remedy is helpdesk application which is widely used in Enterprise Helpdesk systems to log, create, resolve and escalate calls.
What is the hottest part of the computer?
Probably either the CPU or the video card, depending on what sort of application you are running.
What temperature does a standard CPU melt?
CPUs are made of silicon, which melts at about 1400 degrees centigrade. However, other components of the CPU would be damaged long before the chip reached this temperature.
What are the three steps of the RCIA program?
there are actually four steps and they are: evangilization, catechumenate, purification and enlightenment and mystagogy.
How can you build your own computer operating system and language?
If you're coming here and asking such a question then I suggest that it is beyond your capabilities.
How to write your own function for standard library functions strcat strcpy strcmp?
Though i cannot think of a reason do to it (why not use the available methods in the string.h ?) , it is possible to do it manually.
Loop through your character arrays and compare / copy.
Suppose you are char orig[100];
strcmp:
for (int i=0; orig[i] != 0; i++)
if (orig[i] != other[i]) return false;
return true; // because reached the end of the string.
and copy will be similar:
first get the length:
int length = 0;
for (int i=0; orig[i] !=0; i++, length++);
char *other = new char[length];
for (int i=0; i < length; i++)
other[i] = orig[i]; // will also copy the \0
int strcmp(const char *a, const char *b)
{
do
if (*a != *b) return *a - *b;
while (a++, *b++);
return 0;
}
strcpy is even simpler:
char *strcpy(char *dest, const char *src)
{
char *s = dest;
while (*dest++=*src++)
;
return s;
}
strcat is similar to strcpy, but it first finds the end of the dest string before copying the src string to it. I'll leave that as an exercise to the reader.
Why are people who are good at languages good at programming?
This is not necessarily true.
It depends on how good you are a programming rather then speaking languages.
It may be that people who come from different countries speak the language of where they come from and decide to do programming as their job.
How does a computer programmer use fractions?
A computer programmer can use fractions in his/her program simply by turning the fraction into a decimal. In a language like java, there is not extensive support nor a primitive data type for fractions, but you can store fractions as their decimal equivalents in things such as floats and doubles.
How do you copy a flowchart from the raptor program and paste it in a Microsoft word document?
As Microsoft Word is more leters and words it may not be the best way to do flowcharts in. If you choise to put a picture of a flowchart in Word then is should be a simple matter of copy and paste
What is the algorithmic unsolvability?
There are many problems for which it can be proven that they are, at least in the general case, unsolvable - in other words, no algorithm can ever be found to solve them. As an example, one of the first problems for which this unsolvability has been proven is the Halting Problem - determining whether an arbitrary computer program will ever stop, or run forever. Alan Turing showed that solving the halting problem is not possible, in the general case. Note that for some specific computer programs, it might be possible to show that they stop, or that they will continue running forever - but such an algorithm is not possible for ALL computer programs.
What is the difference between c and c plus plus extension?
c language is the structure oriented language and c does not follows the object oriented paradigms . c++ obeys the all object oriented language characteristics
==========
C++ is a set of extensions to the C language to allow some (not all) principles of object-oriented programming to be used. Originally, C++ was a front end pre-processor for C and C++ compilers will translate C language functions.
What is the technical name for the volatile computer workspace that is erased whenever turned off?
RAM (Random Access Memory) or working memory
What do you do when your laptop says the following file is missing or corrupt?
Restore the missing or corrupt file from backup.
What does primitive method mean in programming?
All the objects in Alice that have a set of common set of built-in methods for performing basic options.
I assume you mean a maze with walls. Use a right hand algorithm. Basically always turn right and follow the wall to the end of the maze. You will need to use the ultrasonic sensor for distance to keep in centered on the path. If the maze is tape on the floor and no walls, then use the light sensor to trace the line on the ground.

How did the Colossus work without any software?
Colossus worked by holes punched in a paper tape. It was programmed by switches and plugs. Colossus used thermionic valves (vacuum tubes) to perform Boolean and counting operations.
What is the purpose of buffer register?
here, just the registers are used to store the temporary data in the variables instead of RAM.
How do you make Pentium II ACPI compliant?
ACPI is a function of the hardware and the BIOS. Most Pentium II motherboards do have ACPI, but you cannot add ACPI to a system that does not. If you cannot get ACPI to work, check to see if it is enabled in the BIOS.
What is the maximum number of IP addresses available?
In IPv4, which uses 4x bytes or 32 bits, there is a theoretical maximum of 4,294,967,296 IP addresses. In IPv6, which attempts to resolve the address shortage, uses 128bits, giving a maximum of ~ 340,282,366,920,938,463,463,374,607,431,770,000,000 addresses.
