Network

A cellular telephone operator or wireless operator is a telephone industry that provides services for cell phone users. The operator distributes the SIM card to customers who insert it into the cellphone to gain access to the service. Based on the use of speed, the network is broken down in part by GPRS (Gram), EDGE (E), 3G, H or HPSA / HSDPA, 4G or LTE, and 5G which is currently being raised by SAMSUNG providers.

OS Platfrom

enerally, the designation of the operating system is often intended for all soft features included in a package with the PC system just before the software features application is installed. The operating system is a system software feature whose job is to carry out control and management of hard features and basic system operations, listed as implementing software features such as word processing programs and website browsers.

In many problems, the Operating System provides a library of functions - standard functions, where other applications can call those functions, so that in every new program creation, there is no need to create these functions from an early age.

The operating system is universally composed of several parts:

  • Boot mechanism, is putting kernel into RAM memory
  • Kernel, which is the core of an operating system
  • Command Interpreter or shell, which is tasked with reading / read input from users
  • Libraries, that is, which provides a collection of basic functions and standards that can be called by other applications
  • Driver to interact with external hardware, as well as to control it.

Chipset

A chipset centralizes information from the CPU to the Chipset. Instead the Chipset is split into 2 main component parts, Northbridge and Southbridge. Northbridge controls memory Chace, Main Memory, Host Bus and PCI expansion slots. Instead Soutbridge controls ISA Bis, and bridges between ISA Bis and PCI Bis, controls and controls I / O ports and Inspiration slots. The chipset also ensures the speed of the front-side bus, memory bus and graphics bus, and the capacity and type of memory supported by the motherboard. Not only that, the chipset centralizes the flow of information via PCI buses, Ilham drives and I / O ports and ensures Ilham standards are also the type of ports supported by the system.

CPU

The CPU acts like a calculator, it's just that the CPU is much more robust processing energy. The main use of the CPU is to perform arithmetic and logic operations on information taken from memory or from data entered via some hard feature, such as a keyboard, scanner, control lever, or mouse. The CPU is controlled using a set of PC soft feature instructions. These soft features can be run by the CPU by reading it from storage media, such as hard disks, diskettes, solid discs, or tape. These instructions are then placed first in the physical memory (MAA), where each instruction is given a unique address that is said to be the memory address. Next, the CPU can access the data in the MAA by ensuring the desired address information.

GPU

Graphics processing unit or Graphics processing unit or GPU (or also commonly spoken visual processing unit or VPU) is a special processor for the 3D graphics part of the microprocessor. This equipment is used in embedded systems, mobile phones, individual PCs, workstations, and game consoles. Modern GPUs are very effective in manipulating PC graphics and parallel structures, making them more efficient than the universal CPU used for various algorithm calculations. On individual PCs (Computers), GPUs are generally present on the video card or on the motherboard. More than desktop PCs and notebooks have integrated GPUs, which are generally far from those found on video cards.
