Why were notebooks developed
Laptop terminology and definition
Another great advantage of a laptop is that the device has both location-independent as well as independent of infrastructure can be used. This is because laptops have a battery that allows them to do this for a period of time. Due to the further development in the field of processors and other components, the laptop is constantly on the advance and slowly develops into the market leader and will displace the classic workstation computer from the top position in the course of time.
Originally the laptop was also known as a Notebook designated. This term was introduced by Toshiba in the late 1980s. The term notebook was therefore chosen in order to be able to bring the device to the man better because of its dimensions and its properties. The terms laptop and notebook are used synonymously. Laptop here refers to the fact that you can use it on your lap.
History of the laptop
The first thoughts regarding a laptop were conceived back in 1972. This was the first time people talked about constructing a flat housing in which both the screen and the keyboard were to be housed. However, this Dynabook did not become real because the technical developments were still lacking at the time. in 1979 it became the first computer developed what could be called a laptop.
The GRiD Compass 1100 designed by Bill Moggridge was then sold for the first time three years later. The main memory at that time was 340 kB, which was a lot. This idea could not convince, however, since the laptop is not compatible with other systems, especially IBM, was compatible.
IBM released the IBM PC Convertible four years later. This had a memory of 256 kB, two 3.5 ″ floppy drives, an LCD screen and a clock speed of 4.77 MHz as well as printer connections, so that it can be said here that this was the first laptop to use was able to achieve success in the market.
Compare laptop with desktop PCs
The laptop is inferior to a PC from the same generation. One of the reasons for this is that the Processing power of the processors depends on the cores and their timing. There is also a reason to be seen in the graphics chips. If you take a closer look at these properties, you will come to the conclusion that a great deal of energy has to be expended here, which is also a great one Heat development entails. This heat is less of a problem with a PC than with a laptop. Because of its construction, the laptop is very limited in terms of the installation of components and cooling devices. As a result, less high-quality and powerful components are installed in a laptop than in a PC. However, larger laptops that have these components are now also available.
However, these have a lower value Battery life and a significantly higher weight. Today, however, a laptop is enough to do the standard tasks and replace the PC. This can also be proven on the basis of the sales figures. In 2008, laptops were ahead of PCs with a total market share of 55%.
A big advantage that the PC has over the laptop is the fact that here individual Components can be exchanged more easily and quickly are than with the laptop. With a laptop you are partly dependent on the manufacturer, as they often only have their own components for exchange. With a PC, on the other hand, connections and devices are now almost identical everywhere, so that theoretically everything could be installed anywhere. The design also plays a major role, because rounded side parts, for example, make replacement difficult in that you don't always have the same roundness on one Spare part finds.
What are the components of a laptop?
The components built into a laptop have been designed for difficult use. They include the processor, the screen, the keyboard, the random access memory and the hard diskto name just a few examples. The processor regulates the power consumption of the laptop. Special laptop processors reduce this and thus help to extend the battery life.
However, the same processors are often used as in a PC, which can be attributed both to cost reasons and to the performance of these processors. The screen used on a laptop ranges in size from about 10 ″ to 20 ″. They have roughly the same performance characteristics as that Monitorsconnected to a PC. You can also connect the laptop to an external monitor. Most laptops have the usual connections such as HDMI or VGA and DVI.
The keyboard on the laptop is usually installed without the number pad. With larger models, however, there is the possibility that this is integrated into the keyboard. The keyboard is easier to use on a laptop than on a PC.
Most laptops offer the option of just two Memory banks to obstruct. For a PC it can be up to six. In addition, these are more difficult to replace than with a PC if they are not already soldered in from the start.
As with everything with a laptop, the hard drive is also available in a relatively small 2.5 ″ format. This also has an effect on the storage capacity, which is usually between 750 and 1500 GB on good hard drives. Today will usually be SATA hard drives used. These offer the advantage that their connections are standardized and compatible with a conventional PC, so that they can also be used in a desktop PC with an appropriate framework. Typically, a laptop only has one hard drive, but some devices can have up to two hard drives.
In most cases, a laptop also has a so-called one optical drive. This is the name for CD, BluRay and DVD drives. For these drives, every manufacturer has a suitable frame in which these drives can be used.
The power supply for the laptop runs on two different systems. On the one hand, there are so-called for stationary operation Docking stations, via which the power supply is ensured, or the simple power cord that leads directly to the socket. For mobile use, the laptops have a rechargeable battery that, depending on the model, ensures a mains-independent power supply for several hours. The battery is charged as soon as the laptop is operated again via one of the two stationary variants or is simply connected to the power supply. Most manufacturers are still using it at the moment Lithium-ion batteries, but these are soon to be replaced by lithium polymer cells. Batteries can also be replaced at any time today, although these were still permanently installed a few years ago.
