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. They handle the computation of graphics in various applications. 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 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.
If you have cellular data service, when you are in a location with WiFi, you can use the iPad Settings to temporarily turn off your cellular data service and use a WiFi connection instead. This will help you to avoid exceeding the maximum allowed data transfer on your monthly cellular plan and save on data service charges. It is recommended to use WiFi whenever it's available on-campus, in a hotel, or at a conference for example. Reserve the cellular data service for when there is no WiFi available to you.
This means you can use your iPad with Cellular for maps and navigation which is great if you're going to use it on a boat or plane, or just for walking around touring a city - just make sure your get a water proof case if you're taking it out on the seas! You can quickly tell if an iPad has cellular by looking at the top back of the iPad - if there's a thick black or white band like the one below you know it has cellular that's where all the antennae go For once an explanation that provides exactly what you need to know, nothing more , nothing less..

I just want to make use of its 3G data for browsing. I mean can we make a call or sending messages with t Does This iPad support Sim card calling??
I mean can we make a call or sending messages with this iPad?? JoshuaReen, 18 Aug Either that, or this device's operating system is corrupted. I don't know how to fix I have this model from
