Light Ultra Powerful Laptop

A lap­top, often called a note­book or “note­book com­put­er”, is a small, portable per­son­al com­put­er with a  form fac­tor, an alphanu­mer­ic key­board on the low­er part of the “clamshell” and a thin LCD or LED com­put­er screen on the upper por­tion, which is opened up to use the com­put­er. Lap­tops are fold­ed shut for trans­porta­tion, and thus are suit­able for mobile use. Although orig­i­nal­ly there was a dis­tinc­tion between lap­tops and note­books, the for­mer being big­ger and heav­ier than the lat­ter, as of 2014, there is often no longer any dif­fer­ence. Lap­tops are com­mon­ly used in a vari­ety of set­tings, such as at work, in edu­ca­tion, and for per­son­al mul­ti­me­dia and home com­put­er use.

A lap­top com­bines the com­po­nents, inputs, out­puts, and capa­bil­i­ties of a desk­top com­put­er, includ­ing the dis­play screen, small speak­ers, a key­board, point­ing devices (such as a touch­pad or track­pad), a proces­sor, and mem­o­ry into a sin­gle unit. Most 2016-era lap­tops also have inte­grat­ed web­cams and built-in micro­phones. Some 2016-era lap­tops have touch­screens. Lap­tops can be pow­ered either from an inter­nal bat­tery or by an exter­nal pow­er sup­ply from an AC adapter.

Hard­ware spec­i­fi­ca­tions, such as the proces­sor speed and mem­o­ry capac­i­ty, sig­nif­i­cant­ly vary between dif­fer­ent types, makes, mod­els and price points. Design ele­ments, form fac­tor, and con­struc­tion can also vary sig­nif­i­cant­ly between mod­els depend­ing on intend­ed use. Exam­ples of spe­cial­ized mod­els of lap­tops include rugged note­books for use in con­struc­tion or mil­i­tary appli­ca­tions, as well as low pro­duc­tion cost lap­tops such as those from the One Lap­top per Child orga­ni­za­tion, which incor­po­rate fea­tures like solar charg­ing and semi-flex­i­ble com­po­nents not found on most lap­top com­put­ers.

In terms of the tech­nol­o­gy I use the most, it’s prob­a­bly a tie between my Black­ber­ry and my Mac­Book Pro lap­top. That’s how I com­mu­ni­cate with the rest of the world and how I han­dle all the busi­ness I have to han­dle.

Portable com­put­ers, which lat­er devel­oped into mod­ern lap­tops, were orig­i­nal­ly con­sid­ered to be a small niche mar­ket, most­ly for spe­cial­ized field appli­ca­tions, such as in the mil­i­tary, for accoun­tants, or for trav­el­ing sales rep­re­sen­ta­tives. As portable com­put­ers evolved into the mod­ern lap­top, they became wide­ly used for a vari­ety of pur­pos­es.
As the per­son­al com­put­er  became fea­si­ble in 1971, the idea of a portable per­son­al com­put­er soon fol­lowed. A “per­son­al, portable infor­ma­tion manip­u­la­tor” was imag­ined by Alan Kay at Xerox PARC in 1968, and described in his 1972 paper as the “Dyn­a­book”. The IBM Spe­cial Com­put­er APL Machine Portable  was demon­strat­ed in 1973. This pro­to­type was based on the IBM PALM proces­sor. The IBM 5100, the first com­mer­cial­ly avail­able portable com­put­er, appeared in Sep­tem­ber 1975, and was based on the SCAMP pro­to­type.

As 8-bit CPU machines became wide­ly accept­ed, the num­ber of porta­bles increased rapid­ly. The Osborne 1, released in 1981, used the Zilog Z80 and weighed 23.6 pounds . It had no bat­tery, a 5 in  CRT screen, and dual 5.25 in  sin­gle-den­si­ty flop­py dri­ves. In the same year the first lap­top-sized portable com­put­er, the Epson HX-20, was announced. The Epson had an LCD screen, a recharge­able bat­tery, and a cal­cu­la­tor-size print­er in a 1.6 kg (3.5 lb) chas­sis.

Both Tandy/RadioShack and HP also pro­duced portable com­put­ers of vary­ing designs dur­ing this peri­od. The first lap­tops using the flip form fac­tor appeared in the ear­ly 1980s. The Dul­mont Mag­num was released in Aus­tralia in 1981–82, but was not mar­ket­ed inter­na­tion­al­ly until 1984–85. The US$8,150 GRiD Com­pass 1101, released in 1982, was used at NASA and by the mil­i­tary, among oth­ers. The Gav­i­lan SC, released in 1983, was the first com­put­er described as a “lap­top” by its man­u­fac­tur­er.
