The single-board Odroid-XU4 PC by Hardkernel, released in 2015, has got its new modified successor, called Odroid-XU4Q, which allows to construct devices for smart houses and Internet of things. There are no profound changes, though. A new version obtained a rather large sized (40 х 40 х 25 mm) heatsink instead of a low-profile fan. Such a solution makes the PC operation completely silent.
The board is based on the Samsung designed Exynos 5422 processor; the chipset is built on the ARM big.LITTLE architecture – it has four Cortex-A15 cores with up to 2.0 GHz clock speed and four Cortex-A7 cores with up to 1.4 GHz frequensy. The integrated Mali-T628 MP6 controller provides graphics processing.
The novelty from Hardkernel features 2 GB of RAM, a microSD card slot, one HDMI 1.4, one USB 2.0, two USB 3.0 and Gigabit Ethernet interfaces. The flash module capacity can be equal to 16, 32 or 64 GB.
Customers can purchase a monoboard ODROID-XU4Q PC at the approximate $60 …
Fujitsu introduces a new line of monitors that dramatically improve desktop PC ergonomics. The line is represented by three models: universal B Line, stylish X Line, and professional P Line. If compared with the previous generation of monitors designed by Fujitsu, these monitors are characterized by a faster startup activity, brighter display, heightened resolution, and more power-efficient operation. The latter is of crucial importance, since a new series consumes 60% less power than older models.
All three models are targeted primarily at corporate clients who spend the whole day at their PCs. According to the developers' words, monitors with 22-27 inch displays are the most suitable options for a prolonged work, since their ergonomic facilities (eye-care friendly, functional stand that allows changing the height and pitch of the display) ensure comfortable work during long hours on end.
Fujitsu P Line P27T-7 features 27-inch display with 2560 x 1440 resolution (QHD). …
Hong Kong manufacturer of graphics cards Inno3D announced the delivery of two fresh products based on the base of the graphics core Nvidia GK104 and the original cooling system Arctic Accelero Hybrid, — iChill GTX 680 iChill GTX and LCS 670 LCS.
It should be noted that the models Inno3D iChiLL Black Series GeForce GTX 680 Accelero Hybrid and Inno3D iChiLL Black Series GeForce GTX 670 Accelero Hybrid withdrawal of excess heat is engaged in a hybrid cooler ARCTIC Accelero Hybrid. New models use NWO Danish contractor Asetek to cool the GPU. It includes a water block with copper base and a built-in pump, rubber tubes that extend to the radiator, and 120-mm fan with PWM speed control. Batteries and GDDR5 memory chips are covered with a flat radiator (PA plate) in black, which is blown by 80-mm fan attached to three slot casing.
Inno3D and Arctic promise significant improvement in temperature of CPU GK104, which made it possible to raise the frequency from 1006 (1058) / 6008 …

Ühendus ARVUTIGA Internetti ei saa teha otse, ilma assistent – modem. Modem (modulaator-demodulaatorid) on spetsiaalne seade, mis muundab signaali line pakkuja digitaalsete andmete, распознаваемые arvuti. Toonide vahel online võrgu ja ARVUTI täna kasutavad erinevaid kanaleid (rida kaabel TV, telefoniliinid või raadiotelefonide mobiilsideoperaatorid) ja eriline juht modemid.
Kaasaegne modemid on esindatud lai valik mudeleid, millel on erinev ehitus, tööpõhimõte ja tüüpi ühendus.
Osa projekteerimine, seadme andmed jagunevad sise-ja välispoliitika. Kodused mudel ühendada otse emaplaadil vastav PCI-pesa ja ei ole oma toide. Nad ei erine suure jõudlusega ja ei võimalda visuaalselt kontrollida sätted.
Välised seadmed on riietatud sõjaks oma keha ja on toiteplokk. Nad on ühendatud arvutiga läbi COM või USB porti ja võimaldab visuaalselt kontrollida tingimusi ühendus, tänu juuresolekul näitajate aktiivsus.
Mis puudutab põhimõtet töö modemid, siis nad jagunevad riistvara, kus kõik toimingud, et muuta signaali tehakse ise modemi ja tarkvara, kus seda funktsiooni vastab kesk-protsessor on ARVUTI süsteem. Et tagada stabiilsus tulemus sisend/väljund signaali, tasub lihtsalt alla laadida tasuta juht modemid.
Lõpuks, osad, ühendused, modemid võib jagada on viis liiki: kaabel, analoog -, raku -, raadio-ja ADSL. Seadme esimest tüüpi Interneti-ühenduse loomiseks kasutavad televisiooni-või koaksiaalkaabel, seadme tüüp – telefonikaabel, kolmanda liigi – protokolle võrguteenuse GPRS/EDGE. Ühendust raadio-modemid, kasutades raadio-lained, ja девайсы ADSL kasutavad telefoni võrgu enda vahemikus.
