11110000

11110000 is an 8‑bit binary number. Each of the eight digits is a binary digit (bit) that can be either 0 or 1, and the value of the number is calculated from the sum of powers of two represented by each bit. In this case the leftmost four bits are all 1, giving the value 2^7 + 2^6 + 2^5 + 2^4 = 240, while the remaining four bits are 0. Thus the binary number 11110000 is equivalent to the decimal number 240.

In hexadecimal notation, which groups four binary bits into one digit, 11110000 becomes F0. The full 32‑bit representation of the number in hexadecimal would be 00000000F0. Interpreting 11110000 in various computing contexts can produce different meanings. When treated as an 8‑bit value, it may be used as a mask or flag in low‑level programming, or as a color component in 24‑bit RGB images where the component is saturated (255) in the red channel and zero in the green and blue channels if the most significant bit is ignored. In networking, 11110000 could represent a subnet mask portion of an IPv4 address, indicating that the first four bits of the address are fixed.

The convenience of binary patterns like 11110000 lies in its clear visual representation of bit level operations. Programmers often use such patterns when they need to set, clear, or test specific groups of bits in registers or memory. Because the number has a simple structure, it is also common in educational materials that illustrate the concept of bit manipulation and binary arithmetic.
