Micro-
''Micro'' (Greek letter μ ( U+03BC) or the legacy symbol µ (U+00B5)) is a unit prefix in the metric system denoting a factor of 10−6 (one millionth). Confirmed in 1960, the prefix comes from the Greek ('), meaning "small". The symbol for the prefix is the Greek letter μ ( mu). It is the only SI prefix which uses a character not from the Latin alphabet. "mc" is commonly used as a prefix when the character "μ" is not available; for example, "mcg" commonly denotes a microgram. This may be ambiguous in rare circumstances in that ''mcg'' could also be read as a ''micrigram'', i.e. 10−14 g; however the prefix '' micri'' is not standard, nor widely known, and is considered obsolete. The letter u, instead of μ, was allowed by an ISO document, but that document has been withdrawn in 2001, however DIN 66030:2002 still allows this substitution. Examples * Typical bacteria are 1 to 10 micrometres (1–10 µm) in diameter. * Eukaryotic cells are typically 10 to 100 microm ...

Microcontroller
A microcontroller (MCU for ''microcontroller unit'', often also MC, UC, or μC) is a small computer on a single VLSI integrated circuit (IC) chip. A microcontroller contains one or more CPUs ( processor cores) along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips. In modern terminology, a microcontroller is similar to, but less sophisticated than, a system on a chip (SoC). An SoC may connect the external microcontroller chips as the motherboard components, but an SoC usually integrates the advanced peripherals like graphics processing unit (GPU) and Wi-Fi interface controller as its internal microcontroller unit circuits.

Millionth
One millionth is equal to 0.000 001, or 1 x 10−6 in scientific notation. It is the reciprocal of a million, and can be also written as . Units using this fraction can be indicated using the prefix "micro-" from Greek, meaning "small". Numbers of this quantity are expressed in terms of μ (the Greek letter mu). "Millionth" can also mean the ordinal number that comes after the nine hundred, ninety-nine thousand, nine hundred, ninety-ninth and before the million and first.. See also * International System of Units * Micro- * International Map of the World * Order of magnitude (numbers) * Order of magnitude * Parts-per notation * Per mille Per mille (from Latin , "in each thousand") is an expression that means parts per thousand. Other recognised spellings include per mil, per mill, permil, permill, or permille. The associated sign is written , which looks like a percent sig ...

Windows-1253
Windows code page 1253 ("Greek - ANSI"), commonly known by its IANA-registered name Windows-1253 or abbreviated as cp1253, is a Microsoft Windows code page used to write modern Greek. It is not capable of supporting the older polytonic Greek. It is not fully compatible with ISO 8859-7 because a few characters, including the letter Ά, are located at different byte values: * µ and ¶ are added at their locations from Windows-1252 and ISO 8859-1 ( 0xB5 and 0xB6). This collides with the locations of ΅ and Ά, respectively, in ISO 8859-7. * ‘ and ’ are moved from their ISO 8859-7 locations (0xA1 and 0xA2) to their Windows-1252 locations (0x91 and 0x92). The displaced ΅ and Ά are moved to the vacated space at 0xA1 and 0xA2 respectively. * ¤ and ¥ are added at their locations from Windows-1252 and ISO 8859-1 (0xA4 and 0xA5). This collides with additions made to ISO 8859-7 in 2003, when € and ₯ respectively were added to the same locations. The € was added to Windows ...

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicode
Unicode, formally The Unicode Standard,The formal version reference is is an information technology standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic scripts, as well as symbols, emoji (including in colors), and non-visual control and formatting codes. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, and most modern programming languages. The Unicode character repertoire is synchronized with ISO/IEC 10646, each being code-for-code identical with the other. ''The Unicode Standard'', however, includes more than just the base code.

ISO/IEC 8859-1
ISO/IEC 8859-1:1998, ''Information technology — 8-bit single-byte coded graphic character sets — Part 1: Latin alphabet No. 1'', is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. ISO/IEC 8859-1 encodes what it refers to as "Latin alphabet no. 1", consisting of 191 characters from the Latin script. This character-encoding scheme is used throughout the Americas, Western Europe, Oceania, and much of Africa. It is the basis for some popular 8-bit character sets and the first two blocks of characters in Unicode. ISO-8859-1 was (according to the standard, at least) the default encoding of documents delivered via HTTP with a MIME type beginning with "text/" ( HTML5 changed this to Windows-1252). , 1.3% of all (but only 8 of the top 1000) web sites use . It is the most ''declared'' single-byte character encoding in the world on the Web, but as Web browsers interpret it as the superset Windows-1252, the docume ...

EN 60062
The RKM code, also referred to as "letter and numeral code for resistance and capacitance values and tolerances", "letter and digit code for resistance and capacitance values and tolerances", or informally as "R notation" is a notation to specify resistor and capacitor values defined in the international standard IEC 60062 (formerly IEC 62) since 1952. It is also adopted by various other standards including DIN 40825 (1973), BS 1852 (1975), IS 8186 (1976) and EN 60062 (1993). The updated IEC 60062:2016, amended in 2019, comprises the most recent release of the standard. Overview Originally meant also as part marking code, this shorthand notation is widely used in electrical engineering to denote the values of resistors and capacitors in circuit diagrams and in the production of electronic circuits (for example in bills of material and in silk screens). This method avoids overlooking the decimal separator, which may not be rendered reliably ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
