Microcomputer - ib tug microcomputer rau lub qhov rais ...

Microcomputer - yog, feem ntau, ib tug laptop computer los yog ib tug laptop, ib zaug xwb central processor uas yog ib tug microprocessor. Lawv yog siv rau cov kev laij ua hauj lwm, kev tswj tsis yooj yim txheej txheem. Tej microcomputers nruab nrog peripheral pab kiag li lawm, thiab nws qhia, thiab analog-rau-digital converters, printers, thiab lwm tus.

Basic nta ntawm lub microcomputer

• Bus kev twb kev txuas system pab kiag li lawm.
• Sau kom tiav kev koom ua ke ntawm hardware thiab software.
• Ib tug loj tus naj npawb ntawm tej cov neeg muas zaub.

hom microcomputers

• Nyob Ruaj Ruaj. Qhov no hom yog lub nrov tshaj plaws thiab ntau. Nws muaj ib tug hluas system unit, uas yog cov txheej txheem ntawm nyias los ntawm cov sab nraud pab kiag li lawm. Vim hais tias yog dab tsi yog ib tug microcomputer tsis muaj ib tug nas, keyboard thiab ntawm cov hoob kawm zaub? Ib tug cais system unit yog tau mus cuag lwm sab nraud ntaus ntawv, xws li ib tug tshuab luam ntawv, ib tug gaming joystick, cov lus qhia.
• Portable. Niaj hnub no, qhov no hom kuj ua heev nrov. Lub nto moo tshaj plaws thiab dav portable microcomputer - ib tug laptop. Nws txawv los ntawm lub yav dhau los ib tug xwb nyob rau hauv uas cov sab nraud thiab sab hauv pab kiag li lawm ua ke nyob rau hauv ib tug tsev. Tab sis lwm tsos tsis noj tam sim tau mus txuas rau ib microcomputer lwm pab kiag li lawm.
• Network. Thaum nyob rau hauv 1990, sai pib los tsim ib tug thoob ntiaj teb network, muaj ib tug xav nyob rau hauv lub invention network ntawm microcomputers. Qhov no hom no yog tsim los ua hauj lwm tsuas yog nyob rau hauv lub network. Lawv yog cov ntau pheej yig dua tshaj ib tug taag los portable, txij li thaum lawv yuav tsis tau drives thiab ib tug private nco. Thiab tsis ntev telecommunication lag luam, tsev kawm ntawv thiab lwm yam kev kawm hauv tsev yuav tau siab nruab nrog networked microcomputers.
• Hnab tshos. Me PDA uas 200-400 grams, yog zoo haum nyob rau hauv lub Palm. Tsis li ntawd, ntev dhau los, namely nyob rau hauv 1990, muaj PDAs nrog operating systems. Qhov no muab ib lub sij hawm mus pauv ntaub ntawv nrog rau lwm cov computers thiab microcomputers, raws li zoo raws li txuas mus rau lub thoob ntiaj teb web. Hnab tsho microcomputers tsis muaj tus tsav thiab lub zog tsav. Feem ntau ntawm cov computers kov, tab sis tseem muaj cov qauv nrog ib tug me me keyboard.

Tshiab Ainol

Muaj ntau zoo-paub Suav lub tuam txhab Ainol tso microcomputer rau lub qhov rais 8.1. Ib tug me me ntaus ntawv qhov luaj li cas ntawm 145 x 116 x 15 hli thiab weighing 330 grams, yog ntau tshaj li ib tug sab nraud nyuaj tsav, es cov haib microcomputer, tab sis nws yog ib tug tiag tiag PC. Tus ntaus ntawv boasts ib tug quad-zaus 1,33-1,83 GHz RAM 2 GB thiab kev flash unit 32 GB, nrog rau cov tseem yuav nthuav mus txog 128 GB siv ib daim credit card nco. Tus txheem USB 2.0 chaw nres nkoj ntxiv USB 3.0, Micro HDMI 1.4. Nyob rau hauv tas li ntawd, tus ntaus ntawv yog txawm peem rau nrog Wi-nkaus thiab Bluetooth.

Qhov no microcomputer rau lub qhov rais nruab nrog ib tug haib roj teeb - 7000mA, uas tso cai rau rau ib ntev lub sij hawm mus ua hauj lwm nrog cov ntaus ntawv tsis recharging los ntawm cov mains. Tsaug rau nws cov roj teeb khoom txawm yuav them rau koj lub xov tooj los yog ntsiav tshuaj. Plus, lub nras muaj xws li ib tug console rau yooj yim siv ntawm tus dais, uas yog kev nyob rau hauv lub keyboard.

Qhov zoo tshaj plaws ib leeg-board microcomputer

Qhov no invention yog ntshai li qhov zoo tshaj plaws cov uas zoo sib xws nyob ruaj nrees computer systems, thiab nws tus nqi ua rau cov neeg siv kom yuav tsis muaj xav rau lawv tus kheej thiab pom zoo rau cov phooj ywg. Tab sis tsis muaj ib nqe yuav thov cov neeg siv cov ntawm no ntaus ntawv.

khoom noj khoom haus

Nyob rau hauv thiaj li yuav pub rau cov microcomputer txiv pos Pi, koj yuav tsum 5V thiab lub tam sim no lub dag lub zog ntawm 700 MA (ntau dua qhov zoo, tseem ceeb tshaj, tsis muaj tsawg) thiab ib tug microUSB cable. Zoo kawg nkaus suited chargers Kua Iphone thiab Nokia. Tiam sis peb yuav tsum tsis txhob sim mus them cov ntaus ntawv ntawm lub USB chaw nres nkoj ntawm lub computer.

Rau yooj yim siv pos Pi board muab HDMI chaw nres nkoj. Qhov no yuav tso cai rau mus tau yooj yim cuag cov ntaus ntawv mus rau ib lub TV los yog saib. Nws tshwm sim hais tias tus saib tsis txhawb HDMI, nyob rau hauv uas cov ntaub ntawv koj muaj peev xwm siv lub HDMI-DVI adapter los yog dog dig "tulip".

Txiv pos Pi board muaj 2 ports, uas koj mus cuag tej keyboard los yog nas. Thiab nyob rau hauv kev txiav txim mus cuag cov network ustroystvok, raws li ib txwm, yuav tsum tau ethernet-cable. Suffice nws txuas ntawm ib tug ntaus ntawv mus rau ib tug router los yog lwm yam khoom siv.

Txhim kho lub OS

Yuav ua li cas yog ib tug microcomputer tsis muaj ib qhov system operating? Ruaj xwb. Ua ntej koj yuav pib lub txiv pos Pi, prerecorded OS duab yuav tsum nyob rau hauv lub microSD-phaib. Qhov no yuav ua tau los ntawm ib lub computer los ntawm loading lub OS duab los ntawm lub ntsiab RPi page. Tom qab lub cim xeeb daim ntawv, koj muaj peev xwm pib npaj tso txiv pos Pi, li no booting.

1. Koj yuav tsum tau ntxig ib tug nco card mus rau hauv lub qhov thiab txuas lub ntaus ntawv mus rau lub hwj huam mov.
2. Thaum cov khau raj txheej txheem tau pib nyob rau hauv cov zaub ntaus ntawv yuav ua reloaded dua. Nws nyob rau ntawm uas operating system tau raug xaiv.
3. Nws yuav tsum kis tau tus qauv txheej txheem installation.
4. Tom qab ntawd koj yuav tau ua nyob rau hauv lub peev xwm. Lawv yuav tsum saib cov OS download page.

Mus ua hauj lwm nrog ib tug paub interface rau ntau, koj yuav tsum nkag mus rau ib tug kev hais kom ua nyob rau hauv lub ntaus ntawv.

Qhov no microcomputer - qhov no yog yeej ib pob nyiaj kev xaiv, tab sis nws muaj peev xwm mus qhia loj kev ua tau zoo rau nws cov neeg siv.

Lub microcomputer Cubieboard

Tom qab cov xav tsis thoob zoo txiv pos Pi Suav engineers txiav txim siab kom rov hais dua lawv triumph, thiab tau launched ib tug tshiab uas tsis muaj nqi version ntawm lub microcomputer - Cubieboard. Nruab nrog no ntaus ntawv haib NPAB processor nrog ib zaus ntawm 1 GHz. Mali400 video card tso cai rau koj los qhuas ib tug zoo zoo HD qhov muag. 1 GB ntawm random nkag nco thiab 4 GB ntawm Internal nco, uas lub loader thiab cov kev khiav hauj lwm qhov system yuav tsum tau ntsia. Raws li nyob rau hauv lub txiv pos Pi ntaus ntawv muaj ib tug HDMI tso zis uas tso cai rau mus txuas rau tej saib los yog TV, muaj ib tug tau mus siv cov thoob ntiaj teb network ntawm ethernet-cable, thiab ob tug USB thiab muab tso rau hauv board ib tug infrared chaw nres nkoj.

Muaj xws li ib tug microcomputer tsuas 49 dollars. Rau xws li ib tug ntaus ntawv yog tsis ntau, thiab kev ua hauj lwm yuav tsum muab raws li. Rau cov neeg uas nyiam kom muaj kev lom zem, nyob rau hauv tas li ntawd rau tag nrho cov kev pab txhawb nqa rho pin 96.

Yog thawj batch ntawm 200 kuaj tso tawm, uas muag sai sai heev. Yog li ntawd, manufacturers tam sim ntawd pib qhov muag ntawm lub thib ob batch twb nyob rau hauv 1000 cov ntawv luam. Tej hype nyob ib ncig ntawm lub ntaus ntawv originated los ntawm lub fact tias nws yog tus koom tes ntawm cov nyiaj, thiab qhov tseem ceeb luag hauj lwm ua si los ntawm cov nyiaj them yug ntawm nws lub zej lub zos.

Nco ntsoov hais tias cov microcomputer - qhov no yog qhov uas pheej yig tshaj thiab feem ntau compact daim ntawv ntawm tag nrho cov uas zoo sib xws kiag li lawm. Nws twb yuav luag tag nrho cov cuab yeej hais tias ib tug ruaj ruaj los yog portable computer, thiab tsis inferior rau lawv nyob rau hauv cov nqe lus ntawm kev ua tau zoo thiab tus nqi tsuas yog lub cim qhia txog qhov tseeb hais tias lub tsos yog tsis heev xwb. Txawm li cas los, yuav xws li ib tug ntaus ntawv rau 25-80 dollars, ob peb heev neeg yuav pom yuav ua li cas nws zoo nkaus li. Txawm tias nws ua haujlwm zoo cov yam ntxwv yog tsau, xws li ib tug ntaus ntawv yog heev tsim.
