Kay of the Xerox Palo Alto Research Center had a vision for a wireless portable computer roughly the size of a notebook.

Design elements, form factor and construction can also vary significantly between models depending on intended use. The terms laptop and notebook are used interchangeably to describe a portable computer in English, although in some parts of the world one or the other may be preferred. 1971, the idea of a portable personal computer soon followed. As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The portable micro computer Portal of the French company R2E Micral CCMC officially appeared in September 1980 at the Sicob show in Paris. It was a portable microcomputer designed and marketed by the studies and developments department of R2E Micral at the request of company CCMC specializing in payroll and accounting. The Osborne 1, released in 1981, was a luggable computer that used the Zilog Z80 and weighed 24.

1991, with increases in resolution and screen size occurring frequently until the introduction of 17″ screen laptops in 2003. Hard drives started to be used in portables, encouraged by the introduction of 3. 5″ drives in the late 1980s, and became common in laptops starting with the introduction of 2. Since the introduction of portable computers during late 1970s, their form has changed significantly, spawning a variety of visually and technologically differing subclasses. The form of the traditional laptop computer is a clamshell, with a screen on one of its inner sides and a keyboard on the opposite, facing the screen.

It can be easily folded to conserve space while traveling. The screen and keyboard are inaccessible while closed. Subnotebooks are usually smaller and lighter than standard laptops, weighing between 0. The netbook is an inexpensive, light-weight, energy-efficient form of laptop, especially suited for wireless communication and Internet access.

Netbooks first became commercially available around 2008, weighing under 1 kg, with a display size of under 9″. This section does not cite any sources. The latest trend of technological convergence in the portable computer industry spawned a broad range of devices, which combined features of several previously separate device types. The hybrids, convertibles and 2-in-1s emerged as crossover devices, which share traits of both tablets and laptops. Convertibles are devices with the ability to conceal a hardware keyboard. Keyboards on such devices can be flipped, rotated, or slid behind the back of the chassis, thus transforming from a laptop into a tablet.

Hybrids have a keyboard detachment mechanism, and due to this feature, all critical components are situated in the part with the display. 2-in-1s are designed to be used not only as a media consumption device, but also as valid desktop or laptop replacements, due to their ability to run desktop applications, such as Adobe Photoshop. Microsoft Surface Pro-series devices and Surface Book are examples of modern 2-in-1 detachables, whereas Lenovo Yoga-series computers are a variant of 2-in-1 convertibles. A desktop-replacement laptop is a class of large device which is not intended primarily for mobile use. They are bulkier and not as portable as other laptops, and are intended for use as compact and transportable alternatives to a desktop computer. Desktop replacements are larger and typically heavier than other classes of laptops.

A rugged laptop is designed to reliably operate in harsh usage conditions such as strong vibrations, extreme temperatures, and wet or dusty environments. Rugged laptops are usually designed from scratch, rather than adapted from regular consumer laptop models. Rugged laptops are bulkier, heavier, and much more expensive than regular laptops, and thus are seldom seen in regular consumer use. The design features found in rugged laptops include a rubber sheeting under the keyboard keys, sealed port and connector covers, passive cooling, very bright displays easily readable in daylight, cases and frames made of magnesium alloys that are much stronger than plastics found in commercial laptops, and solid-state storage devices or hard disc drives that are shock mounted to withstand constant vibrations. A business laptop is a laptop designed for those in a workplace. Typically, it is ruggedised, with consumer facing features, like high resolution sound removed to allow the device to be used for pure productivity.

This section needs additional citations for verification. The basic components of laptops function identically to their desktop counterparts. Traditionally they were miniaturized and adapted to mobile use, although desktop systems increasingly use the same smaller, lower-power parts which were originally developed for mobile use. The following sections summarizes the differences and distinguishing features of laptop components in comparison to desktop personal computer parts. Typically, laptop CPUs have two processor cores, although 4-core models are also available. There have been a wide range of CPUs designed for laptops available from both Intel, AMD, and other manufacturers.

Do You Have to Pay Taxes on Unemployment Income?

In the past, some laptops have used a desktop processor instead of the laptop version and have had high performance gains at the cost of greater weight, heat, and limited battery life, but the practice was largely extinct as of 2013. Unlike their desktop counterparts, laptop CPUs are nearly impossible to overclock. CPU to conserve power and space. Most laptops can contain a single 2. 5-inch drive, but a small number of laptops with a screen wider than 15 inches can house two drives.

Some laptops support a hybrid mode, combining a 2. 5-inch drive, typically a spacious HDD for data, with an mSATA or M. 2016-era laptops use lithium ion batteries, with some thinner models using the flatter lithium polymer technology. A laptop’s battery is charged using an external power supply which is plugged into a wall outlet.

The power supply outputs a DC voltage typically in the range of 7. The power supply is usually external, and connected to the laptop through a DC connector cable. In most cases, it can charge the battery and power the laptop simultaneously. Waste heat from operation is difficult to remove in the compact internal space of a laptop.

Early laptops used heat sinks placed directly on the components to be cooled, but when these hot components are deep inside the device, a large space-wasting air duct is needed to exhaust the heat. A laptop connects and disconnects to a docking station, typically through a single large proprietary connector. Laptop charging trolleys, also known as laptop trolleys or laptop carts, are mobile storage containers to charge multiple laptops, netbooks, and tablet computers at the same time. Laptop charging trolleys are also used to deter and protect against opportunistic and organized theft.

Schools, especially those with open plan designs, are often prime targets for thieves who steal high-value items. In some laptops, solar panels are able to generate enough solar power for the laptop to operate. The One Laptop Per Child Initiative released the OLPC XO-1 laptop which was tested and successfully operated by use of solar panels. A common accessory for laptops is a laptop sleeve, laptop skin, or laptop case, which provides a degree of protection from scratches. Portability is usually the first feature mentioned in any comparison of laptops versus desktop PCs.

Physical portability allows a laptop to be used in many places—not only at home and at the office, but also during commuting and flights, in coffee shops, in lecture halls and libraries, at clients’ locations or at a meeting room, etc. Productivity: Using a laptop in places where a desktop PC cannot be used can help employees and students to increase their productivity on work or school tasks. For example, an office worker reading their work e-mails during an hour-long commute by train, or a student doing their homework at the university coffee shop during a break between lectures. Immediacy: Carrying an laptop means having instant access to information, including personal and work files. This allows better collaboration between coworkers or students, as a laptop can be flipped open to look at a report, document, spreadsheet, or presentation anytime and anywhere.

Up-to-date information: If a person has more than one desktop PC, a problem of synchronization arises: changes made on one computer are not automatically propagated to the others. Size: Laptops are smaller than desktop PCs. This is beneficial when space is at a premium, for example in small apartments and student dorms. When not in use, a laptop can be closed and put away in a desk drawer. Low power consumption: Laptops are several times more power-efficient than desktops.

CPU, hard drive, power supply, etc. While the performance of mainstream desktops and laptop is comparable, and the cost of laptops has fallen less rapidly than desktops, laptops remain more expensive than desktop PCs at the same performance level. Most higher-end laptops are sufficiently powerful for high-resolution movie playback, some 3D gaming and video editing and encoding.

Upgradeability of laptops is very limited compared to desktops, which are thoroughly standardized. In general, hard drives and memory can be upgraded easily. Prolonged use of laptops can cause repetitive strain injury because of their small, flat keyboard and trackpad pointing devices,. A laptop’s integrated screen often requires users to lean over for a better view, which can cause neck or spinal injuries.
