What is the difference between null pointer ASCII null character and null string?
A null pointer is a pointer which does not point to any valid memory location, and usually contains the binary value "0" to represent this (this is language dependent). The ASCII null character is a character-sized zero value (in ASCII, it is an unsigned byte with a value of 0), and typically represents the end of a string (esp. as in C and C++). A null string is one that is zero characters of usable string data; in a length-based string, this means the length parameter is set to 0, and in an ASCII null-terminated string, means the first character is set to 0.
How can you convert byte to string in java?
To convert byte to String in java use the String(bytes, UTF-8); //example for one encoding type. You must know the special encoding that contains a variety of characters.
What is the use of little endian and big endian?
"Little Endian" means that the lower-order byte of the number is stored in memory at the lowest address, and the high-order byte at the highest address. For example, a 4 byte Integer Byte3 Byte2 Byte1 Byte0 will be arranged in memory as follows: Base Address+0 Byte0 Base Address+1 Byte1 Base Address+2 Byte2 Base Address+3 Byte3 Intel processors (those used in PC's) use "Little Endian" byte order. "Big Endian" means that the high-order byte of the number is stored in memory at the lowest address, and the low-order byte at the highest address. The same 4 byte integer would be stored as: Base Address+0 Byte3 Base Address+1 Byte2 Base Address+2 Byte1 Base Address+3 Byte0 Motorola processors (those used in Mac's) use "Big Endian" byte order.
What are the system requirements for language c?
1. byte-organised memory (every bytes of the memory has to be accessible) 2. support for every ASCII characters (0-127)
A string of eight 0s and 1s is called?
Eight binary digits are called a byte.Four binary digits are a nibble.
A byte stored in AL is present in array of 10 bytes stored in the memory Store the number of occurrences of the byte in register AH?
Of 10 bytes simply stored in the memory? YAWN...
How much memory is required to store a 'character' and how much is required to store a 'string'?
a character/byte as defined in the C programming language is one byte (8 bits). A string can be as short as one byte and can be as long as the physical memory limits can contain it.
Which character in string is used to end the string?
Character zero (the byte with the decimal value zero) is sometimes used to end a string. But in other cases, the size of the string is stored at the beginning of the string, and there is no end-of-string character. This allows any character to be included in the string.
How many bits are stored by a 256 x 4 memory chip can this chip be specified as 128 byte memory?
256x4=1024 bits are stored.128x8=1024 ,yes this chip can be specified as 128 byte
What is the largest positive integer that can be stored in memory size of 1 byte?
255
What is the smallest memory size and how does it compare to a bit?
The smallest memory size is a single bit, capable of storing either a 1 or a zero. An electronic component that does this is known as a D latch and in it's simplest form has three pins. The data input pin will have the value to be stored. The clock or enable pin is the trigger to store the value on the data input pin. Finally the output pin will have the value of the stored data. These single byte memories can be bought as small integrated circuits. Add 8 of these latches together and you have a 1 byte memory. Add 1 byte memories together and you have the basis of computer memory as used in almost all processors.
What is the significance of big-endian byte ordering in Motorola microprocessors?
Big-endian byte ordering in Motorola microprocessors is significant because it determines the way data is stored in memory. In big-endian systems, the most significant byte of a multi-byte data is stored at the lowest memory address, which can impact data manipulation and communication with other systems.
What is the largest prime number stored in 8 bit memory?
The largest number which can be stored in an 8 bit memory byte is 255. The largest prime number below 255 is 251.
What is the largest prime number that can be stored in 8 bit memory?
The largest number which can be stored in an 8 bit memory byte is 255 . The largest prime number below 255 is 251.
What is the largest prime number that can be stored in an 8 bit memory?
The largest number which can be stored in an 8 bit memory byte is 255 .The largest prime number below 255 is 251.
If A word on a little-endian computer has the numerical value of 3 If it is transmitted to a big-endian computer byte by byte and stored there with byte 0 in byte 0 and so on what is its numerica?
In a 32-bit word, the decimal value 3 has hex value 0x00000003. Laid out in memory in a little-endian computer, it is 0x03, 0x00, 0x00, 0x00. If you move that to a big-endian computer without reversing the byte order, you get 0x03000000, which is decimal 50,331,648. The correct big-endian representation should have been 0x00, 0x00, 0x00, 0x03.
What is the smallest unit of memory storage in a memory?
bit
