What was the first laptop and when was it invented?

The first commercially available laptop was the Osborne 1. It used the CP/M Operating System. Likely the first laptop, though, was the Xerox NoteTaker. It used a version of the Smalltalk Operating System.

Why was the laptop made?

The laptop was designed to make a personal computer easily portable.

The first portable computer was the GriD Compass (weighing about 5 kilograms). It was invented by Bill Moggridge in 1979 and cost several thousand dollars when it was first sold in 1982. It was widely used by the military and aboard the Space Shuttle.

The first true laptop was invented by Adam Osborne in 1981. It was called 'Osborne 1' and cost $1,795. It came bundled with $1,500 worth of programmes and had a tiny monitor screen built into it. This first portable computer was a success, with sales reaching 10,000 units a month.

IBM launched the IBM 5155 Portable Personal Computer in 1984. In 1988, Compaq Computer launched the first laptop PC with VGA graphics, the Compaq SLT/286. In 1989, NEC released UltraLite, which was the first lightweight 'laptop' computer. Weighing under 5 lbs, it was the precursor of today's models.

When was the laptop invented?

The first laptop concept that can be found was the "Dynabook" concept (not to be confused with Toshiba's Dynabook laptop line) developed by Alan Kay in 1968. No actual laptop was ever created however, it was simply the laptop concept that was thought up and described.

The first mass-produced portable computer was the "Osborne 1" which became available in 1981. This was a large and heavy machine about the size of a sewing machine, and had a 5" text only monitor. It used the CP/M operating system. It was not sold in large numbers at all.

Arguably the first true laptop made it's appearance in 1982. This was the GRiD Compass 1101. It introduced the familiar clamshell design with it's closing top, and it ran on batteries. It was not an IBM compatible computer, however, and its initial price was between $8 - 10k. Because of it's high price, it was not really a consumer product, but was used by the military and NASA on their work on the space shuttle during the 1980's. GRiD Systems was later bought by Tandy corporation (Radioshack).

Also released in 1982 another contender for the title of the first true laptop was the Dulmont Magnum, which made its appearance in Australia. This was the only laptop ever to be produced in Australia. It also had a clamshell design, and although it had a MS DOS 2.1 operating system, it wasn't really IBM compatible.

By 1983, many other manufacturers such as HP, Sharp, Sanyo, etc. began producing laptops and making them available on the consumer market.

The first IBM PC-compatable laptop made its appearance in 1983, as well. This was the Compaq Portable. It was still rather large and was not battery powered, but required AC power to run.

Which is the world's best computer brand?

It depends on the kind of computer you wish to buy. There are several categories of computers and what individual needs are. Here are some of the best computers for different tasks:

  • Gaming: Alienware- these computers have raw power, perfect for gaming and movies. They are some of the best out there from a technical standpoint.
  • Business: Dell or Apple- While Dell is more affordable and commonly used, if you can afford it go with Apple. An Apple can do absolutely anything a Dell can do and more. Dell however has the upper hand with the affordability and existing use.
  • Art/Music/Film Design: Apple is by far the most evolved and developed brand for designing and creating. This is a staple of the company and rightly so; all their programs run without a hitch and their machines are capable of high processing power
  • Overall use and Reliability: Apple- No matter who you are, if you use an Apple it will just work. They are easy, user friendly and reliable. Virtually no virus' exist for Mac's operating system and it includes so many features that just make since. If you want a computer that just works and will never crash, buy a Mac. They are good at just about everything. (they can run all Windows OS' including windows 7)

Who made the laptop?

The Gavilan SC, released in 1983, was the first computer described as a "laptop" by its manufacturer. The Dulmont Magnum was a flip form top portable computer released in Australia in 1981-82, but it was not called a laptop by its maker.

The first computers that were portable enough to be held on the lap were made in the early 70's. The first demonstrated was the IBM Scamp in 1973.

What brand of laptops is good for engineering students?

See I myself is a student of electrical engineering at a govt. engineering college in india. Well it was too difficult for me too to figure out which laptop I should buy. I have selected some laptops , u can pick up anyone of these based on the price Rs. 10,000-20,000 go for Wipro ego minilaptops Rs. 20,000-30,000 go for Acer aspire laptops based on dual core processor. Rs. 30,000-40,000 U can choose HCL leaptops, they are great value for money. Rs. 40,000-50,000 Go for Sony Vaio VGN series laptops they cost around 45,000 and have core2duo processor. Rs. 50,000-60,000 choose DELL studio 15 - its the best fit for any job. I have this one. Its a fast and responsive laptop with high-definition WLED screen, 512MB graphics card,4GB RAM,500 GB HDD and slot drive. I am loving it. Its Wi-fi capability is superb.We have around 3,500 laptops in our college of different makes. I have compared mine with all others. Mine is the best.......everyone accepts that. Rs. 60,000-70,000 Dell XPS . They are even better than studio laaptops but are quiet costly for a student. beyond 70,000 I have no idea coz i never thought of purchasing a laptop in this range.

Why would your laptop run slowly?

Program data must be accessed from the hard drive and copied into memory, which can take a long time for large programs.

Windows tends to become more resource-intensive with every release, so unless you have cutting-edge hardware it may be slow.

What is the difference between 4000 mAh and 4400 mAh lithium ion battery?

4400 mAh means that the battery can produce 4400 mA for one hour. Similarly, 7200 mAh means 7200 mA for one hour. In reality, these specifications are for a eight-hour rating, meaning that the 4400 mAh battery can produce 550 mA for eight hours but, comparatively, you can just ratio the ratings, so the 7200 mAh battery will last 60% longer than the 4400 mAh battery There's more to it than that, however, as you need to know that the laptop is designed to use either battery, otherwise the camparison is meaningless.

How many transistors would you find in a modern laptop?

A laptop today in mid-2015 typically has about 200 billion transistors in it - this includes the TFT LCD screen, CPU, RAM (memory) and many ASIC and controller chips. To put this in perspective, if today's laptop were made with the 1950s ENIAC vacuum tube ('valve') technology, it would require a space of more than 8.8 billion square feet (94,280 feet on a side. That's 17.8 miles on a side - or 28.5 km per side). This could not be done. A 17 x 17 mile square electronic device built using vacuum tube technology would require more electrical power than all the electrical power plants in the United States could produce, to run it.

This estimate is based on the fact that the ENIAC computer had about 18,000 vacuum tubes and required 800 square feet of floor space.

Now one can see why we are truly living in a paradigm shift; why there's now serious talk about transhumanism and enhanced, immortal man-machine hybrid beings.

(The United States is used as an example because that is where the ENIAC computer was designed, built and operated.)

How many watts are in a laptop?

There are no 'watts' in a laptop.

A laptop, or any other electrical device uses electricity, and Watts measure the rate at which energy is used. Asking how many watts a laptop uses is like asking how many watts a light bulb uses. There are light bulbs that use a small fraction of a watt to those that use more than 1000 watts. As Watts measure energy consumption, it does not necessarily mean electricity: A person having a mass of 100 kilograms who climbs a 3-meter-high ladder in 5 seconds is doing work at a rate of about 600 watts.

It depends on the laptop as to how many watts it uses.

In electrical terms, one watt is the rate at which work is done when one ampere of current flows through an electrical potential difference of one volt.

When W=Watts; V=Volts; I=Amps; R=resistance in Ohms, then W = VI or W = I2R or E2/R

I have a netbook that uses a 19 volt, 1.5amp power supply. As Watts = Volts x Amps, it would appear that it uses 19 x 1.5 or 28½ watts. But that is only the power supply rating, The maximum the netbook uses is probably closer to half of that. The power supply is most likely very overrated. It operates nicely with the power supply when the battery is exhausted and being charged at the same time as being used.

Is it bad to use a laptop on the bed?

Few points

1. If used on bed without any hard flat surface under the laptop, primarily you should be concerned about heat the laptop generates. With insufficient cooling, the laptop may shutdown when it gets overheated.

2. You may also sleep while using the laptop and may drop the laptop on the floor and damage it.

3. If you eat and drink while using laptop on bed, chances are more that you may spil some thing on the machine.

4. If you have no other option but to use the machine on bed, make sure you use some large wooden board or any large hard book under the machine to allow for air circulation under the laptop.

-----

It's OK to use your laptop on the bed if you have something underneath it. For example, a book underneath your laptop will do good. The reason for this is, the heat produced by the laptop is really hot, and when there is nothing shielding the sheets ( they are highly flammable), it might catch on fire.

IMPORTANT: Do not put your laptop on your lap because:

1. If you're a guy, you have a high risk of catching prostate cancer.

2. If you're a female/girl, you have a high risk of catching any other form of cancer.

____________________________________________________________

Well, i think the main reason is, the laptop cooling fan. Actually mostly laptops has cooling fans on it's base. Fan takes the air from it, and if it is on bed, then no air gets in the laptop. So it becomes hot. This is the main reason manufacturers suggests not to use laptops on bed.

That's it.

Can hardware be changed in laptops?

The hardware inside of laptops can only be changed to a certain degree. You can usually replace the battery, the hard drive, and the RAM. You can sometimes change the networking hardware, but that would have to come from the laptop's manufacturer. You won't be able to change most of the other internal hardware.
