The cache memory is used by the processor in order to shorten the time needed to access data and instructions that a frequently used. The L1 level 1 cache memory has a small volume, but operates faster than the RAM and the rest cache memory levels. If the processor does not find the data needed in L1, it continues to look for it in the L2 cache memory. In some processors the search in L1 and L2 is simultaneous. The L2 level 2 cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data.
Just like L1, it is much faster than the system memory RAM. A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel.
The frequency of the processor describes its clock rate in cycles per second. Data in the RAM is lost after the device is turned off or restarted. More channels mean higher data transfer rates.
Information about the capacity of the built-in storage of the device. Sometimes one and the same model may is offered in variants with different internal storage capacity. The various types of memory cards are characterized by different sizes and capacity.
Information about the supported types of memory cards. The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content. Information about the number of pixels per centimeter ppcm or per inch ppi of the display. The higher the pixel density, the more detailed and clearer is the information displayed on the screen.
The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display. Sensors vary in type and purpose. They increase the overall functionality of the device, in which they are integrated.
The aperture f-stop number indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening. The rear cameras of mobile devices use mainly a LED flash.
Before placing any order at our database, make sure that your HTC Hero asks for an unlock code. To confirm, just change the default simcard with any other carrier simcard and switch ON the phone. It should prompt for network unlock code. This site uses Akismet to reduce spam. Learn how your comment data is processed. Sign in. Log into your account.
