In computer science, the sign bit is a bit in a computer numbering format that indicates the sign of a number. In IEEE format, the sign bit is the leftmost bit (most significant bit). Typically if the sign bit is 1 the number is negative (in the case of two's complement integers) or non-positive (for ones' complement integers, sign-magnitude integers, and floating point numbers), while 0indicates a positive number.
Nothing, there is no such thing.
On the other hand, a bit can represent the sign of a number, e.g. 1=negative, 0=non-negative.
11 bits (which actually allows -1024 to 1023)
The highest unsigned integer is 255; The highest signed integer is 127.
000000 is the lowest number in a 6 bit unsigned binary number (meaning the high order bit is not the sign bit). If it is a signed number then the lowest number would be represented by 100000 which is equivalent to -32 in decimal. Highest unsigned number in 6 bits is decimal 63. Highest signed number in 6 bits is decimal 31.
A nibble is 4 bits, so the largest unsigned number is 1111, or 15. Also, the largest signed number is 0111, or 7.
A signed integer represents both positive and negative values, while an unsigned integer represents only positive values. Range depends on the number of bits the compiler assigns for the representation. bits max-negative max-positive max-unsigned 8 -128 +128 255 16 -32768 +32767 65535 32 -2147483648 +2147483647 4294967295 64 -9223372036854775808 +9223372036854775807 18446744073709551615
8 bits if unsigned, 9 bits if signed
If the 8 bits represent a signed number, the range is usually -128 to +127. This is -27 to 27-1.

Using 4 bits the signed range of numbers is -8 to 7. When working with signed numbers one bit is the sign bit, thus with 4 bits this leaves 3 bits for the value. With 3 bits there are 8 possible values, which when using 2s complement have ranges: for non-negative numbers these are 0 to 7; for negative numbers these are -1 to -8. Thus the range for signed 4 bit numbers is -8 to 7.

BITS Pilani runs an extension center in Bangalore for "off-campus" students. These students are employees of various companies like Intel, Yahoo, etc and are eligible to be BITS students under the MoUs signed by their respective companies and BITS. There is NO admission procedure for the extension center.BITSAT is the way to get admission to any of the "on-campus" programs at the BITS Pilani, Pilani, Goa and Hyderabad Campuses.
signed magnitude
The qualifier signed or unsigned may be applied to char or any integer. unsigned numbers are always positive or zero, and obey the laws of arithmetic modulo 2n, where n is the number of bits in the type. So, for instance, if charsare 8 bits, unsigned charvariables have values between 0 and 255, while signed charshave values between -128 and 127 (in a two's complement machine.) Whether plain charsare signed or unsigned is machine-dependent, but printable characters are always positive.
The highest unsigned integer is 255; The highest signed integer is 127.
