TechTarget, Inc. (doing business as Informa TechTarget) is an American company that offers data-driven marketing services to business-to-business technology vendors. TechTarget, Inc. was founded in 1999; it is headquartered in Newton, Massachusetts, with offices in London, Munich, Paris, San Francisco, Singapore and Sydney.
Game Developer (known as Gamasutra until 2021) is a website created in 1997 that focuses on aspects of video game development. It is owned and operated by Informa TechTarget and acted as the online sister publication to the print magazine Game Developer prior to the latter's closure in 2013.
InformationWeek is a digital magazine which conducts corresponding face-to-face events, virtual events, and research. It is headquartered in San Francisco, California and was first published in 1985 by CMP Media, later became part of Informa TechTarget. The print edition of the magazine has ceased, with the last issue published on June 24, 2013.
A central processing unit (CPU), also known as a central processor, main processor, or simply processor, is the primary processor in a given computer. Its electronic circuitry executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. This role contrasts with that of external components, such as main memory and I/O circuitry, and specialized coprocessors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers, and other components. Modern CPUs devote a lot of semiconductor area to caches and instruction-level parallelism to increase performance and to CPU modes to support operating systems and virtualization. Most modern CPUs are implemented on integrated circuit (IC) microprocessors, with one or more CPUs on a single IC chip. Microprocessor chips with multiple CPUs are called multi-core processors (MCPs). The individual physical CPUs, called processor cores, can also be multithreaded to support CPU-level multithreading. An IC that contains a CPU may also contain memory, peripheral interfaces, and other components of a computer; such integrated devices are variously called microcontrollers or systems on chip (SoCs).
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
