Price–performance Ratio
In economics, engineering, business management and marketing the price–performance ratio is often written as cost–performance, cost–benefit or capability/price (C/P), refers to a product's ability to deliver performance, of any sort, for its price. Generally speaking, products with a lower price/performance ratio are more desirable on demand curve, excluding other factors. Even though this term would seem to be a straightforward ratio, when price performance is improved, better, or increased, it actually refers to the performance divided by the price, in other words exactly the opposite ratio (i.e. an inverse ratio) to rank a product as having an increased price/performance. Examples Consumer and medical products According to futurist Raymond Kurzweil, products start out as highly ineffective and highly expensive. Gradually, products become more effective and cheaper until they are highly effective and almost free to buy. Some of the products that have followed this ex ...

Economics
Economics () is a behavioral science that studies the Production (economics), production, distribution (economics), distribution, and Consumption (economics), consumption of goods and services. Economics focuses on the behaviour and interactions of Agent (economics), economic agents and how economy, economies work. Microeconomics analyses what is viewed as basic elements within economy, economies, including individual agents and market (economics), markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyses economies as systems where production, distribution, consumption, savings, and Expenditure, investment expenditure interact; and the factors of production affecting them, such as: Labour (human activity), labour, Capital (economics), capital, Land (economics), land, and Entrepreneurship, enterprise, inflation, economic growth, and public policies that impact gloss ...

Therapy
A therapy or medical treatment is the attempted remediation of a health problem, usually following a medical diagnosis. Both words, ''treatment'' and ''therapy'', are often abbreviated tx, Tx, or Tx. As a rule, each therapy has indications and contraindications. There are many different types of therapy. Not all therapies are effective. Many therapies can produce unwanted adverse effects. ''Treatment'' and ''therapy'' are often synonymous, especially in the usage of health professionals. However, in the context of mental health, the term ''therapy'' may refer specifically to psychotherapy. Semantic field The words ''care'', ''therapy'', ''treatment'', and ''intervention'' overlap in a semantic field, and thus they can be synonymous depending on context. Moving rightward through that order, the connotative level of holism decreases and the level of specificity (to concrete instances) increases. Thus, in health-care contexts (where its senses are always nonc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benefit–cost Ratio
A benefit–cost ratio (BCR) is an indicator, used in cost–benefit analysis, that attempts to summarize the overall value for money of a project or proposal. A BCR is the ratio of the benefits of a project or proposal, expressed in monetary terms, relative to its costs, also expressed in monetary terms. All benefits and costs should be expressed in discounted present values. A BCR can be a profitability index in for-profit contexts. A BCR takes into account the amount of monetary gain realized by performing a project versus the amount it costs to execute the project. The higher the BCR the better the investment. The general rule of thumb is that if the benefit is higher than the cost the project is a good investment. The practice of cost–benefit analysis in some countries refers to the BCR as the cost–benefit ratio, but this is still calculated as the ratio of benefits to costs. Rationale In the absence of funding constraints, the best value for money projects are those wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyramid Technology
Pyramid Technology Corporation was a computer company that produced a number of RISC-based minicomputers at the upper end of the performance range. It was based in the San Francisco Bay Area of California They also became the second company to ship a multiprocessor UNIX system (branded DC/OSx), in 1985, which formed the basis of their product line into the early 1990s. Pyramid's OSx was a dual-universe UNIX which supported programs and system calls from both 4.xBSD and AT&T's UNIX System V. History Pyramid Technology was formed in 1981 by a number of ex-Hewlett-Packard employees, who were interested in building first-rate minicomputers based on RISC designs. Pyramid licensed its multiprocessor bus technology to Fujitsu/ ICL in 1993, also entering into a marketing partnership in certain markets that would see ICL sell Pyramid server products and offer integration services with ICL's existing mainframe products. Such sales arrangements were to continue into 1994, by which time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequent Computer Systems
Sequent Computer Systems, Inc. was a computer company that designed and manufactured multiprocessing computer systems. They were among the pioneers in high-performance symmetric multiprocessing (SMP) Open system (computing), open systems, innovating in both hardware (e.g., cache (computing), cache management and interrupt handling) and software (e.g., read-copy-update). Through a partnership with Oracle Corporation, Sequent became a dominant high-end Unix, UNIX platform in the late 1980s and early 1990s. Later they introduced a next-generation high-end platform for UNIX and Windows NT based on a non-uniform memory access architecture, NUMA-Q. As hardware prices fell in the late 1990s, and Intel shifted their server focus to the Itanium processor family, Sequent joined the Project Monterey effort in October 1998, which aimed to move a standard Unix to several new platforms.

Multiprocessor
Multiprocessing (MP) is the use of two or more central processing units (CPUs) within a single computer system. The term also refers to the ability of a system to support more than one processor or the ability to allocate tasks between them. There are many variations on this basic theme, and the definition of multiprocessing can vary with context, mostly as a function of how CPUs are defined ( multiple cores on one die, multiple dies in one package, multiple packages in one system unit, etc.). A multiprocessor is a computer system having two or more processing units (multiple processors) each sharing main memory and peripherals, in order to simultaneously process programs. A 2009 textbook defined multiprocessor system similarly, but noted that the processors may share "some or all of the system’s memory and I/O facilities"; it also gave tightly coupled system as a synonymous term. At the operating system level, ''multiprocessing'' is sometimes used to refer to the executio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data General
Data General Corporation was an early minicomputer firm formed in 1968. Three of the four founders were former employees of Digital Equipment Corporation (DEC). Their first product, 1969's Data General Nova, was a 16-bit minicomputer intended to both outperform and cost less than the equivalent from DEC, the 12-bit PDP-8. A basic Nova system cost two-thirds or less than a similar PDP-8 while running faster, offering easy expandability, being significantly smaller, and proving more reliable in the field. Combined with Data General RDOS (DG/RDOS) and programming languages like Data General Business Basic, Novas provided a multi-user platform far ahead of many contemporary systems. A series of updated Nova machines were released through the early 1970s that kept the Nova line at the front of the 16-bit mini world. The Nova was followed by the Data General Eclipse, Eclipse series which offered much larger memory capacity while still being able to run Nova code without modification. T ...

Digital Equipment Corporation
Digital Equipment Corporation (DEC ), using the trademark Digital, was a major American company in the computer industry from the 1960s to the 1990s. The company was co-founded by Ken Olsen and Harlan Anderson in 1957. Olsen was president until he was forced to resign in 1992, after the company had gone into precipitous decline. The company produced many different product lines over its history. It is best known for the work in the minicomputer market starting in the early 1960s. The company produced a series of machines known as the Programmed Data Processor, PDP line, with the PDP-8 and PDP-11 being among the most successful minis in history. Their success was only surpassed by another DEC product, the late-1970s VAX "supermini" systems that were designed to replace the PDP-11. Although a number of competitors had successfully competed with Digital through the 1970s, the VAX cemented the company's place as a leading vendor in the computer space. As microcomputers improved in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business Trip
Business travel is travel undertaken for work or business purposes, as opposed to other types of travel such as leisure trips or daily commuting between one’s home and workplace. It typically involves travelling - often by air, rail, or road - to attend meetings, conferences, trade shows, or other professional events that require in-person interactions. Historically, in-person meetings have been viewed as critical for activities such as closing deals, networking, and conducting negotiations. However, advances in digital communication tools over the last few decades have started to reshape this landscape. The rise of videotelephony and other virtual collaboration technologies has made it increasingly feasible to hold effective meetings without requiring employees to travel, causing a recent reduction in business travel. More recently, widespread adoption of remote work and virtual meeting solutions has further contributed to a reduction in business travel. Despite these shi ...

Financial Capital
Financial capital (also simply known as capital or equity in finance, accounting and economics) is any Economic resources, economic resource measured in terms of money used by entrepreneurs and businesses to buy what they need to make their products or to provide their services to the sector of the economy upon which their operation is based (e.g. retail, corporate, investment banking). In other words, financial capital is internal retained earnings generated by the entity or funds provided by lenders (and Investor, investors) to businesses in order to purchase real capital equipment or services for producing new Goods and services, goods or services. In contrast, real capital comprises physical goods that assist in the production of other goods and services (e.g. shovels for gravediggers, sewing machines for tailors, or machinery and tooling for factories).

Unemployment
Unemployment, according to the OECD (Organisation for Economic Co-operation and Development), is the proportion of people above a specified age (usually 15) not being in paid employment or self-employment but currently available for work during the reference period. Unemployment is measured by the unemployment rate, which is the number of people who are unemployed as a percentage of the labour force (the total number of people employed added to those unemployed). Unemployment can have many sources, such as the following: * the status of the economy, which can be influenced by a recession * competition caused by globalization and international trade * new technologies and inventions * policies of the government * regulation and market * war, civil disorder, and natural disasters Unemployment and the status of the economy can be influenced by a country through, for example, fiscal policy. Furthermore, the monetary authority of a country, such as the central bank, can in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microcomputer
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). An early use of the term "personal computer" in 1962 predates microprocessor-based designs. ''(See "Personal Computer: Computers at Companies" reference below)''. A "microcomputer" used as an embedded control system may have no human-readable input and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
