00010100

00010100 is an eight-bit binary numeral. As a binary string it represents the decimal value 20 and the hexadecimal value 0x14. In contexts that use binary notation, it may appear as an unsigned byte or as part of a larger bitfield or data word.

In ASCII encoding, the byte 00010100 corresponds to the control character DC4 (Device Control 4). DC4 is a non-printable control code and is rarely used in modern text processing, but it forms part of the standard ASCII control code set used in historical telecommunication and data signaling.

As a bitmask, 00010100 can indicate that two specific bits are set within a byte. If the least significant bit is designated as bit 0, the pattern activates bits 2 and 4, equating to the values 4 and 16, for a total of 20. Such a pattern is common in low-level programming and hardware interfacing where individual flags or options are tracked within a single byte.

In programming, 00010100 may be written directly in languages that support binary literals (for example, with a 0b prefix in languages that permit it) or expressed in hexadecimal as 0x14. When transmitted or stored, the meaning of this byte depends on the surrounding protocol or data structure, and without context it represents simply the number 20 or a specific bitmask value.
