Contemporary PC monitors are generally based on two types of panels with their variations: TN and IPS. The choice of panel depends on the product's class and destination. However, there are some monitors that employ rather rare arrays, like WVA, which appeared long time ago and now emerge in the market with a bit modified technologies. Acer G276HL is a representative of a small army of monitors based on WVA panel. WVA technology is not new but is called to fulfill all standard assignments to compete with more advanced options.
Specifications and Delivery
Acer G276HL features 27-inch display, 16:9 aspect ratio and 1920x1080 resolution. The monitor employs WVA panel type (6 ms response time) and is equipped with LED lighting. The claimed brightness equals to 300 cd/m2; this is an average index for a semiprofessional display. The number of displayed colors achieves 16.7 millions. It should be noted that the company does not provide much information about its new product, …
Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.
The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.
As the advantages of such solution can immediately be noted a lower price, due to less stringent …
Production of a new model is positioned as a replacement for modern routers with features of sharing USB-carriers. IS308 — the budget class — single-disk storage is a good device for visiting friends for movies, or for backup. In general, it is used for tasks which are not mission-critical of data loss. The speed and functionality are secondary, the main thing — the price and design. At a price of 90 $, IconBIT IS308 offers the buyer an autonomous Torrent-downloader, a network drive, support for protocols Samba and FTP, gigabit network interface and USB 3.0 port.
The device has stylish black aluminium hull and comes with a stand for vertical installation. IconBIT iS308 looks more like a normal external hard drive rather than the NAS. And if for someone Synology design seems too plastic, and QNAP — too angular, the iconBIT iS308 looks modern, simple and stylish.
The next thing that catches an eye — is the lack of a fan. Finally, there is a NAS with passive cooling. …

Kontroler tvrdog diska сложнейшее uređaj, vrsta miniračunalo s vlastitim procesorom, tako da je čip okrenut upravljanje, RAM i ROM, programima za snimanje i čitanje podataka, sučelje modula i sustav pozicioniranja. Obično je predstavljen jedan-dva микрочипами (u fizičkom obliku), распаянными na ploči, a namijenjen je za provedbu operacija transformacije toka podataka.
Mnogi moderni pogoni karakterizira podrška različitih načina rada, uključujući DMA2, 'UltraDMA i PIO. Kako iskoristiti mogućnosti ovih načina rada, preporučujemo da preuzmete program za kontrolere tvrdih diskova. Režim DMA (Direct Memory Access) korisna onima koji to omogućava znatno rasteretiti procesor RAČUNALA pri operacijama razmjenu podataka; pri tome kontroler je u izravnoj korelaciji sa sučeljem računala. Za razliku od DMAmode PIO koristi centralni procesor prilikom dostavljanja podataka preko sučelja, međutim, kontroler ima direktan pristup ram-a.
Ponekad se operativni sustav ne može prepoznati kontroler hard disk čak i kada instaliranim upravljačkim programima. Razlog za to može poslužiti sljedeće aspekte:
mehanička oštećenja. Prilikom sudara ili padovima elementi гермоблока mogu biti deformirani. Deformacija najčešće izložena modul ili kontakt na mjesto ugradnje čipova. Pri manji stupanj oštećenja, uređaj se može popraviti, ali vijek trajanja elemenata znatno se smanjuje. Također, treba uzeti u obzir mogućnost da su tvornički braka pojedinih elemenata;
električni oštećenja. Učinkovitost hardver na PC-u velikoj mjeri ovisi o stabilnosti napona питанияРа u sustavu. U slučaju prekoračenja, udara ili naglog nestanka napona, kao i elektrostatičkog pražnjenja osigurači lanca opskrbe, energetske čipa ili, u najgorem slučaju, cpu kontroler može выгореть. Često osigurača, popravka bespovratna, a zahtijevaju zamjenu;
zastarjeli upravljački program za kontrolere tvrdih diskova. Ako nadograđujete računalo hardver (ili nekih komponenti) prethodno instalirani programi zahtijevaju ažuriranja za instalaciju odnos sa SUSTAVOM.
