Hyper-threading is a technology developed to help make better use of spare processing cycles. Hyper-threaded processors have a duplicate set of registers, small spaces of high-speed memory storage used to hold the data that is currently needed to execute a thread.

When a CPU core is delayed, waiting for data to be retrieved from another place in memory, it can use these duplicate registers to spend the spare computation cycles executing a different thread. While small and light on energy use, Atom processors can handle the most common tasks, such as email and instant messaging.

Which is the processor suitable from intel family of processors for Server and Workstation? What are the latest Processor of intel and AMD? Socket is developed by AMD. It supports a maximum of how many bits of computing?

What are the the different processors of AMD is suitable for this socket? Which type of socket is needed to connect a dual core processor of intel? Socket LGA What is Heat Sink? What is its use? If it is not in the system what will happen? A heat sink is a component used to lower the temperature of a device. It is most commonly there on the microprocessor. If it is not properly fixed the system, the system will shutdown automatically to prevent further damage to the processor.

A CPU fan should be placed in system. To make the system cool and more functioning. Upgrading a microprocessor is just physically replacing a processor with a new one. We also have to make sure that the motherboard has the internal logic to support the processor. What is the use of Conventional memory in the system? It is also called doS memory or Base memory. It is also known as RAM. This is the part of the computer that stores operating system software, software applications and other information for the central processing unit CPU.

What is Cache memory? What is the advantage if a processor with more cache memory you are using? Cache memory is the memory area between RAM and Processor.

If cache memory increases the speed of the system will also improved. What are the different types of RAM? What are the different DRAM types? DDR 2 incorporates several technological upgrades to computer system memory, as well as an enhanced data rate.

It operates at a lower voltage than DDR-I as well: 1. Video adapter or video system uses VRAM. VRAM is dual ported. It is costly. It is a less expensive approach to graphics functions. Most commonly all low cost graphics cards are using it. It is a smaller version of a dual in-line memory module DIMM. It is the type of the memory module can be used in laptop.

Which is the memory packaging suitable for a sub-note book system? Micro DIMM. EPP is for non-printer peripherals. ECP is for printers and scanners. What is over clocking? Over clocking is the process of forcing a computer component to run at a higher clock rate. What is memory bank? Sets of physical memory modules is referred to as memory banks.

A memory bank serves as a repository for data, allowing data to be easily entered and retrieved. What is Upgrading the memory? Adding a memory module to the existing bank on the available slot or replacing the previous one with the increased memory size is also called upgrading memory. This will surely increase the performance of the computer. What is BIOS beep code? What it does mean? BIOS beep codes are the signs of different issues of the computer.

For example in case of Award BIOS the beep code will be, 1 long beep- shows memory problem 1 long beep and 2 short beeps- failure of DRAM parity 1 log beep and 3 short beeps- signifies Video error Continuous beep- signifies failure in memory or Video memory. What are Solid State Drive means? A solid-state drive SSD , sometimes called a solid-state disk or electronic disk, is a data storage device that uses solid-state memory to store data. SSDs use microchips which retain data in non-volatile memory chips and contain no moving parts.

Compared to electromechanical HDDs, SSDs are typically less susceptible to physical shock, are silent, have lower access time and latency, but are more expensive per gigabyte GB.

What is SIMM? Acronym for Single in line Memory Module, a small circuit board that can hold a group of memory chips. RAM chips. On PCs, the ninth chip is often used for parity error checking. Unlike memory chips, SIMMs are measured in bytes rather than bits. Now a days this memory module is not used. Why do we call motherboard a motherboard?

 А кто же еще! - ответил тот с гордостью.  - Хочу его запатентовать. - Как торговую марку? - Беккер смотрел на него изумленно. Парень был озадачен.

 Вам нужен ключ. Я поняла так, что весь смысл в том, чтобы его уничтожить. - Верно. Но я хочу иметь копию.

Сьюзан встала и быстро подошла к громадному книжному шкафу с техническими руководствами, взяла с полки справочник с прошитым проволочной спиралью корешком и принялась его листать. Она нашла то, что искала, вернулась со справочником к своему терминалу, ввела несколько команд и подождала, пока компьютер проверит список команд, отданных за последние три часа. Сьюзан надеялась обнаружить внешнее воздействие - команду отключения, вызванную сбоем электропитания или дефектным чипом. Через несколько мгновений компьютер подал звуковой сигнал. Сердце ее заколотилось.

Нуматака чуть не расхохотался во весь голос. Он знал, что это трюк. Корпорация Нуматек сделала очень крупную ставку на новый алгоритм Танкадо, и теперь кто-то из конкурентов пытается выведать ее величину. - У вас есть ключ? - сказал Нуматака с деланным интересом.

И, словно возражая ей, в ее мозгу эхом прозвучали слова Хейла, сказанные чуть раньше: Танкадо не раз мне писал… Стратмор сильно рисковал, взяв меня в АНБ… Рано или поздно я отсюда слиняю.

Ты видел кольцо. Двухцветный замер. Как правильно ответить. - Viste el anillo? - настаивал обладатель жуткого голоса. Двухцветный утвердительно кивнул, убежденный, что честность - лучшая политика.

 - Это вовсе не трюк. Да я вообще слова ему не сказал о деньгах. Я попросил оказать мне личную услугу.

 Сьюзан, сядь. Она не обратила внимания на его просьбу. - Сядь.  - На этот раз это прозвучало как приказ. Сьюзан осталась стоять.
