32 bit operating systems can only address 4GB of memory

64 bit operating systems can address 4 petabytes of memory(1 048 576 gigabytes).

How do you install c plus plus 64bits?

The documentation that came with your implementation will tell you how to go about installing it, but other than having a 64-bit machine with a 64-bit operating system there are no special requirements for installing 64-bit C++. You install it just as you would the 32-bit version.

You cannot install a programming language on your computer, only a particular compiler. Pick one.


How do you change Windows XP sp3 32bits to 64bits?

You can't just do that unless the underlying hardware of your computer is 64 bit. The 64 bit version of Windows XP released on April 25, 2005 will not run on a 32 bit computer. If your computer is 64 bit then you can move to 64 bit XP but you would need to purchase this from somewhere. I am not sure but I do not think Microsoft supports or sells this any more. If you are having problems, may I suggest you try installing Linux instead (for free in either 32 or 64 bit versions) it will work much faster then Windows. See related link below.


Explain howby use of the binary systempositive integer numbers are stored on digital computer and explain why binary is used rather than any other base system?

Not sure how they are stored it may vary in different systems and use a different number of bits (e.g. 32bits, 64bits). But the basic binary integer will be an octet, 8 bits, one byte, which can represent 256 different values, from 0 to 255. Binary is used because of the way digital systems work, components in digital systems only recognize the presence or the absence of electrical current. So the presence of current will be 1 and the absence 0. How it is stored in physical terms will also vary depending on the type of memory (i.e.- RAM, Hard drive, CD ROM...etc). In a common hard drive there will be a disc with a magnetic coating, this coating can be manipulated to change its magnetic polarity so it represents either 1 or 0 at any given location of the disc.


Why did computers change and what was the effect What has changed with computers and what has happend in a result of this?

A very good question but no one knows or cares computers do operate for many years but newer software will not run on it A word was 8 bit now it is 64bits and expanding if we kept the same clock speed we just multiply the speed of computing tremendously. RAMS and integration of these chips made the complexity of programming ever expanding.


Is there a new computer bite?

it depends if your terminolgy is correct or not tech. no there is not a new byte. There are new bit systems that can transmit 64bits at a time. Now for ip addresses there is a new byte its called IP-V6 rather than IP-V4 witch all ip addresses will be converted to IP-V6 and is in hexidecimal format but origanly its till bits just more of them and more combinations. right now we use IP-V4 witch go from 0.0.0.0 to 255.255.255.255 the new ip version (IP-V6) is in hexideciamls witch can go from 00:00:00:00:00:00 to FF:FF:FF:FF:FF:FF and uses 0-9 numbers and A-F letters witch gerate huge amounts of possiblites and will be converted to this soon. question is how soon


What Pointer in Data Structure?

No, pointer is not a data type but a reference to an object. Pointers are used to refer back to an object which can be anything from a large data value or a collection of values or objects.A pointer is a variable and is 4 bytes long because 4 bytes = 32 bits, and all addresses in 32 bit operating systems are 4 bytes long :) , so if you want to store an address somewhere you need 4 bytes. A pointer is just 4 bytes in the memory and in these 4 bytes an address is stored. If you ask the address of an element, like char, int, etc., the address you will get will be the address of the first byte. Only the first byte is saved in the pointer, and then you can manipulate the upcoming bytes.For example you declare a structure of 12 bytes and you name it myStruct.let's say that the address of this structure is the address 0x00400001
