Gesellschaft Mit Beschränkter Haftung
A ''Gesellschaft mit beschränkter Haftung'' (, abbreviated GmbH and also GesmbH in Austria; ) is a type of legal entity common in Germany, Austria, Switzerland (where it is equivalent to a ''société à responsabilité limitée''), and Liechtenstein. It is an entity broadly equivalent to the private limited company in the United Kingdom and many Commonwealth countries, and the limited liability company (LLC) in the United States. The name of the GmbH form emphasizes the fact that the owners (''Gesellschafter'', also known as members) of the entity are not personally liable or credible for the company's debts. GmbHs are considered legal persons under German, Swiss, and Austrian law. Other variations include mbH (used when the term ''Gesellschaft'' is part of the company name itself), and gGmbH (''gemeinnützige'' GmbH) for non-profit companies. The GmbH has become the most common corporation form in Germany because the AG (''Aktiengesellschaft''), the other major company form ...

Milpitas, California
Milpitas (Spanish for "little milpas") is a city in Santa Clara County, California, in Silicon Valley. As of the 2020 census, the city population was 80,273. The city's origins lie in Rancho Milpitas, granted to Californio ranchero José María Alviso in 1835. Milpitas incorporated in 1954 and has since become home to numerous high tech companies, as part of Silicon Valley. History Milpitas was first inhabited by Tamien people, a subgroup of the Ohlone people who had resided in the San Francisco Bay Area for thousands of years. The Ohlone Indians lived a traditional life based on everyday hunting and gathering. Some of the Ohlone lived in various villages within what is now Milpitas, including sites underneath what are now the Calvary Assembly of God Church and Higuera Adobe Park.Marvin-Cunningham (1990) Archaeological evidence gathered from Ohlone graves at the Elmwood Correctional Facility in 1993 revealed a rich trade with other tribes from Sacramento to Monterey.

Ethernet
Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the latest , with rates up to under development. The Ethernet standards include several wiring and signaling variants of the OSI physical layer. Systems communicating over Ethernet ...

RISC-V
RISC-V (pronounced "risk-five" where five refers to the number of generations of RISC architecture that were developed at the University of California, Berkeley since 1981) is an open standard instruction set architecture (ISA) based on established RISC principles. Unlike most other ISA designs, RISC-V is provided under open source licenses that do not require fees to use. A number of companies are offering or have announced RISC-V hardware, open source operating systems with RISC-V support are available, and the instruction set is supported in several popular software toolchains. As a RISC architecture, the RISC-V ISA is a load–store architecture. Its floating-point instructions use IEEE 754 floating-point. Notable features of the RISC-V ISA include instruction bit field locations chosen to simplify the use of multiplexers in a CPU, a design that is architecturally neutral, and most-significant bits of immediate values placed at a fixed location to speed sign extension. ...

ARM Architecture
ARM (stylised in lowercase as arm, formerly an acronym for Advanced RISC Machines and originally Acorn RISC Machine) is a family of reduced instruction set computer (RISC) instruction set architectures for computer processors, configured for various environments. Arm Ltd. develops the architectures and licenses them to other companies, who design their own products that implement one or more of those architectures, including system on a chip (SoC) and system on module (SOM) designs, that incorporate different components such as memory, interfaces, and radios. It also designs cores that implement these instruction set architectures and licenses these designs to many companies that incorporate those core designs into their own products. There have been several generations of the ARM design. The original ARM1 used a 32-bit internal structure but had a 26-bit address space that limited it to 64 MB of main memory. This limitation was removed in the ARMv3 series, which ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors 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 co ...
