A used good can also simply mean it is no longer in the same condition as it was when it was first transferred to the current end user. With respect to a quantifiable resources, such as the charge in a battery, it also refers to something which has been partially or completely depleted. The strategy of buying used items is employed by some to save money, as they are typically worth less than the equivalent new items. Purchasing used items for reuse prevents them from becoming waste and saves costly production of equivalent new goods. Motivations for purchase include conserving natural resources and protecting the environment, and may form part of a simple living plan. used goods Wiki used goods surplus computers surplus computersused computer used computer used computer equipment used computer equipment used computer games used computer games used computer hardware used computer hardware used computer sale used computer sale used computers used computers used desktops used desktops used laptop computer used laptop computer used laptop computers used laptop computers used laptops used laptops used notebook computers used notebook computers used notebooks used notebooks used pc used pc laptop computerA laptop computer, or simply laptop is a small mobile computer, which usually weighs 2-18 pounds (around 1 to 8 kilograms), depending on size, materials, and other factors. Laptops usually run on a single main battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself. Many computers also have a 3 volt cell to run the clock and other processes in the event of a power failure. As Personal computers, laptops are capable of the same tasks as a desktop computer, although they are typically less powerful for the same price. They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption. Laptops usually have liquid crystal displays and most of them use different memory modules for their random access memory (RAM), for instance, SO-DIMM in lieu of the larger DIMMs. In addition to a built-in keyboard, they may utilize a touchpad (also known as a trackpad) or a pointing stick for input, though an external keyboard or mouse can usually be attached. A laptop is a notebook computer. Notebook and notepad are laptops. laptop computer For a given price range (and manufacturing base), laptop computational power has traditionally trailed that of desktops. This is partly due to most laptops sharing RAM between the program memory and the graphics adapter. By virtue of their usage goals, laptops prioritize energy efficiency and compactness over absolute performance. Desktop computers and their modular components are built to fit much bigger standard enclosures, along with the expectation of AC line power. As such, energy efficiency and portability for desktops are secondary design goals compared to absolute performance. For typical home (personal use) applications, where the computer spends the majority of its time sitting idle for the next user input, laptops of the thin-client type or larger are generally fast enough to achieve the required performance. 3D gaming, multimedia (video) encoding and playback, and analysis-packages (database, math, engineering, financial, etc.) are areas where desktops still offer the casual user a compelling advantage. With the advent of dual-core processors and perpendicular recording, laptops are beginning to close the performance gap with desktops. Intel's Core 2 line of processors is efficient enough to be used in portable computers, and many manufacturers such as Apple and Dell are building Core 2 based laptops. Also, many high end laptop computers feature mobility versions of graphics cards, eliminating the performance losses associated with integrated graphics. wholesale computer wholesale computer |

A typical modern computer can execute billions of instructions every second and nearly never make a mistake over years of operation. Large computer programs may take teams of computer programmers years to write and the probability of the entire program having been written completely in the manner intended is unlikely. Errors in computer programs are called bugs. Sometimes bugs are benign and do not affect the usefulness of the program, in other cases they might cause the program to completely fail (crash), in yet other cases there may be subtle problems. Sometimes otherwise benign bugs may be used for malicious intent, creating a security exploit. Bugs are usually not the fault of the computer. Since computers merely execute the instructions they are given, bugs are nearly always the result of programmer error or an oversight made in the program's design. In most computers, individual instructions are stored as machine code with each instruction being given a unique number (its operation code or opcode for short). The command to add two numbers together would have one opcode, the command to multiply them would have a different opcode and so on. The simplest computers are able to perform any of a handful of different instructions, the more complex computers have several hundred to choose from—each with a unique numerical code. Since the computer's memory is able to store numbers, it can also store the instruction codes. This leads to the important fact that entire programs (which are just lists of instructions) can be represented as lists of numbers and can themselves be manipulated inside the computer just as if they were numeric data. The fundamental concept of storing programs in the computer's memory alongside the data they operate on is the crux of the von Neumann, or stored program, architecture. In some cases, a computer might store some or all of its program in memory that is kept separate from the data it operates on. This is called the Harvard architecture after the Harvard Mark I computer. Modern von Neumann computers display some traits of the Harvard architecture in their designs, such as in CPU caches.

| Does Recycling Save money? The liquidators would normally require sanction to pay creditors and to make compromises or arrangement with creditors computer sales Kim Kardashian surplus computer surplus computer laptop computer Economist Steven Lands burg has suggested that the sole benefit of reducing landfill space is trumped by the energy needed and resulting pollution from the recycling process. Others, however, have calculated through life cycle assessment that producing recycled paper uses less energy and water than harvesting, pulping, processing, and transporting virgin trees. By using less recycled paper, additional energy is needed to create and maintain farmed forests until these forests are as self-sustainable as virgin forests. This argument is followed from the curbside collection of recyclables, which critics note is often done by a second waste truck in addition to the truck that picks up the regular trash computers for sale Kirsten Dunst used Cisco buyer used Cisco buyer computer monitors Ewaste is Electronic waste. E-waste as Waste Electrical and Electronic Equipment is a waste type consisting of any broken or unwanted electrical or electronic appliance. Recyclable electronic waste is sometimes further categorized as a "commodity" while e-waste which can not be reused is distinguished as "waste". Both types of e-waste have raised concern considering that many components of such equipment are considered toxic and are not biodegradable. Responding to these concerns, many European countries banned e-waste from landfills in the 1990s. The European Union would further advance e-waste policy in Europe by implementing the Waste Electrical and Electronic Equipment Directive in 2002 which holds manufacturers responsible for e-waste disposal at end-of-life. Similar legislation has been enacted in Asia, with e-waste legislation in the United States limited to the state level due to stalled efforts in the United States Congress regarding multiple e-waste legislation bills. Due to the difficulty and cost of recycling used electronics as well as lackluster enforcement of legislation regarding e-waste exports, a staggering amount of used electronics has made its way into countries such as China, India, and Kenya where lower environmental standards and working conditions make processing e-waste more profitable.

Typically, technological systems or computing products that incorporate green computing principles take into account the so-called triple bottom line of economic viability, social responsibility, and environmental impact. This differs somewhat from traditional or standard business practices that focus mainly on the economic viability of a computing solution. These focuses are similar to those of green chemistry; reduction of the use of hazardous materials such as lead at the manufacturing stage, maximized energy efficiency during the product's term of use, and recyclables or biodegradability of both a defunct product and of any factory waste.
