Information:  - An integer (from the Latin "integer" meaning "whole") is a number that can be written without a fractional component. For example, 21, 4, 0, and 2048 are integers, while 9.75, , and  are not.  - Two's complement is a mathematical operation on binary numbers, as well as a binary signed number representation based on this operation. Its wide use in computing makes it the most important example of a radix complement.  - The Motorola 68000 ("'sixty-eight-thousand'"; also called the m68k or Motorola 68k, ""sixty-eight-kay"") is a 32-bit CISC microprocessor with a 16-bit external data bus, designed and marketed by Motorola Semiconductor Products Sector (later Freescale Semiconductor, now NXP). Introduced in 1979 with HMOS technology as the first member of the successful 32-bit m68k family of microprocessors, it is generally software forward compatible with the rest of the line despite being limited to a 16-bit wide external bus. After 37 years in production, the 68000 architecture is still in use.  - A microprocessor is a computer processor which incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits. The microprocessor is a multipurpose, clock driven, register based, programmable electronic device which accepts digital or binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary numeral system.  - Schaumburg is a village located in Cook County in northeastern Illinois, United States. The village is a northwestern suburb of Chicago and is part of the Golden Corridor. Schaumburg is located roughly northwest of the Chicago Loop and approximately northwest of O'Hare International Airport. As of the 2010 census, the village had a total population of 74,227.  - The Motorola 68030 (""sixty-eight-oh-thirty"") is a 32-bit microprocessor in Motorola's 68000 family. It was released in 1987. The 68030 was the successor to the Motorola 68020, and was followed by the Motorola 68040. In keeping with general Motorola naming, this CPU is often referred to as the 030 (pronounced "oh-three-oh" or "oh-thirty").  - In digital circuit theory, combinational logic (sometimes also referred to as time-independent logic ) is a type of digital logic which is implemented by Boolean circuits, where the output is a pure function of the present input only. This is in contrast to sequential logic, in which the output depends not only on the present input but also on the history of the input. In other words, sequential logic has "memory" while combinational logic does not.  - In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system or base-2 numeral system which represents numeric values using two different symbols: typically 0 (zero) and 1 (one). The base-2 system is a positional notation with a radix of 2. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by almost all modern computers and computer-based devices. Each digit is referred to as a bit.  - The Motorola MC68010 processor is a 16/32-bit microprocessor from Motorola, released in 1982 as the successor to the Motorola 68000.  - A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers.  - The Motorola 68040 (""sixty-eight-oh-forty"") is a 32-bit microprocessor from Motorola, released in 1990. It is the successor to the 68030 and is followed by the 68060. There was no 68050. In keeping with general Motorola naming, the 68040 is often referred to as simply the '040 (pronounced "oh-four-oh" or "oh-forty").  - Motorola Mobility is a Chinese-American consumer electronics and telecommunications company founded in 2011 as the result of a split by Motorola, formerly owned by Google and now Lenovo and based in Chicago, Illinois. From the split, Motorola Mobility took on the company's consumer-oriented product lines, including its mobile phone business and its cable modems and set-top boxes for digital cable and satellite television services, while Motorola Solutions retained the company's enterprise-oriented product lines.  - The Motorola 68020 ( `` sixty - eight - oh - twenty '' , `` sixty - eight - oh - two - oh '' or `` six - eight - oh - two - oh '' ) is a 32 - bit microprocessor from Motorola , released in 1984 . It is the successor to the Motorola 68010 and is succeeded by the Motorola 68030 . A lower cost version was also made available , known as the 68EC020 . In keeping with naming practices common to Motorola designs , the 68020 is usually referred to as the `` 020 '' , pronounced `` oh - two - oh '' or `` oh - twenty '' .  - Range for storing integers. A 32-bit register can store 2 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used. With the two most common representations, the range is 0 through 4,294,967,295 (2 - 1) for representation as an (unsigned) binary number, and -2,147,483,648 (-2) through 2,147,483,647 (2 - 1) for representation as two's complement.  - Motorola, Inc. is an American multinational telecommunications company based in Schaumburg, Illinois, United States. After having lost $4.3 billion from 2007 to 2009, the company was divided into two independent public companies, Motorola Mobility and Motorola Solutions on January 4, 2011. Motorola Solutions is generally considered to be the direct successor to Motorola, Inc., as the reorganization was structured with Motorola Mobility being spun off. Motorola Mobility was acquired by Lenovo in 2014.  - Motorola Solutions, Inc. is an American data communications and telecommunications equipment provider that succeeded Motorola, Inc., following the spinoff of the mobile phone division into Motorola Mobility in 2011. The company is headquartered in Chicago, Illinois.  - Lenovo Group Ltd. or shortened as Lenovo, (formerly stylized as lenovo) is a Chinese multinational technology company with headquarters in Beijing, China, and Morrisville, North Carolina, United States. It designs, develops, manufactures and sells personal computers, tablet computers, smartphones, workstations, servers, electronic storage devices, IT management software, and smart televisions. Since 2013, Lenovo is the world's largest personal computer vendor by unit sales. It markets the ThinkPad line of notebook computers, IdeaPad line of notebook laptops, IdeaCentre line of desktops, Yoga line of notebook laptops, and the ThinkCentre line of desktops.
