Motherboard Intel DH77DF is a part of a series Media, which focuses on working with media content, including the creation and viewing of video. Support for high-performance processors and the availability of high-grade graphics card slot allows use it for building a compact gaming systems.
DH77DF uses a blue color PCB material, like many other Intel products of mass series. There is only one indicator green LED of power supply. The board looks very good good, mainly due to the dense deployment of a large number of elements in a limited space. This integration continues to amaze also in the age of quad phones.
The manufacturer managed to install on board two standard slots for memory modules, so that the total amount up to 16 GB — this is also more than enough for most usage scenarios. Officially supported speeds up to DDR3-1600. Test modules by default worked in 1333, but after selecting in BIOS Setup XMP profile it could start in 2000, but with the 2133 system it was not …
XFX has introduced its own version of Radeon HD 7990 — a top-tier graphics adapter from AMD. As distinct from the other companies that incorporated only some inconspicuous changes into their products, XFX has approached to the card’s modification with a violent zeal. As a result, today everyone has a chance of examining its Radeon HD 7990 Triple Dissipation card that employs two Tahiti XT GPUs, elaborated on Graphics Core next architecture.
Each Tahiti XT chip comes with 2048 stream processors and 3 GB of GDDR5 memory. This implies that the total memory capacity makes up 6 GB. GPUs run at 950 MHz clock frequency, but have the potential of achieving 1000 MHz frequency on overclocking. As for the memory, it employs 384-bit bus and runs at an efficient 6 GHz frequency.
To continue, all the components of Radeon HD 7990 Triple Dissipation are housed on an original PCB, designed by XFX. Connection with the PSU is realized via a pair of 8-contact power sockets. The rear …
Asus has recently presented workstations and graphics servers of the second generation ESC series. The new series includes ESC4000 G2, ESC1000 G2 and ESC2000 G2 models which serve the function of high-end platforms for GPGPU applications in such fields as medical research, financial modeling, computer-aided design, animation and 3D-rendering. The systems can boast a wide spectrum of options and outstanding integration; they are able to support high-end Intel processors and four graphics cards, and are equipped with the efficient PSU and expansion slots PCI Express 3.0x16.
All three models of ESC series are furnished with high-quality PSU which correspond to the 80Plus standard. Thereby, each of the models boasts energy-saving facilities: ESC1000 G2 and ESC2000 G2 go with a single PSU of 80Plus Gold standard in 1350 W capacity; ESC4000 G2 goes with two PSU of 80 Plus Platinum standard in 1620 W capacity (one of them is an emergency unit in case of troubles with the other unit). … …

Mouse-ul – dispozitiv mecanic de intrare, трансформирующее mișcarea în direcție semnal. După un drum lung de evoluție, acest indicator rămâne principalul mijloc de comunicare a utilizatorului cu calculatorul. Dar comunicarea eficientă ar fi fost imposibilă fără setări speciale, care oferă conducătorului auto pentru șoareci.
Până în prezent, există 4 tipuri de bază de șoareci de calculator: cu bile, optice, laser și трекбольные.
Cu mouse – atavismele, care încă mai locuiesc în casele de unii utilizatori. În structură intră special mingea de metal, managing cursorul, și două role (orizontal și vertical). Dacă este necesar, pentru a produce acțiunea utilizatorul mișcă o bilă, care transmite direcția de mișcare iese. Principalul dezavantaj al unei astfel de soluții – contaminarea rapidă a шарикового mecanismului și nevoia de a-l regulat de curățare.
Optice model reprezintă un dispozitiv, în cazul în care toate de conducere de acțiune efectuează o mică cameră, iluminarea suprafata de led-uri și фотографирующая de mai multe mii de ori pe secundă. Primita de la fotografierea informațiile sunt prelucrate de interne cpu și instantaneu este trimis la computer.
Laser mouse au un principiu similar de acțiune cu modele optice, numai că în loc de aparat de fotografiat aici se aplică semiconductor laser. La cheie avantajele laser soluții sunt consumul redus de energie electrică, cât mai mare precizie de citire de informații și compatibilitatea cu toate tipurile de suprafețe, inclusiv cu sticla si oglinda.
Трекбольные mouse-ului se întâlnesc extrem de rar. Ei sunt îmbrăcați în extraordinare carcasa și au bombat bec, care permite de a manipula dispozitivul cu un singur deget.
După tipul de conexiune la PC-uri se disting cu fir și fără fir mouse-ului. Cu fir au un cablu-"coada", care se conectează la un port USB sau PS/2. Fără fir funcționează prin intermediul tehnologiei Bluetooth sau prin unde. Raza de acțiune a unor astfel de modele poate varia de la 5 până la 20 pm Pentru a începe de dispozitive de orice tip trebuie să liber pentru a descărca un driver pentru șoareci.
