Smart card
A smart card is a plastic card as on the same size of a credit card. It is embedded with the microchip that can be creating personal and business data available only to the appropriate users. Smart cards are mainly used for telephone calling, electronic cash payments, and other applications. A smart card holds more information than a magnetic stripe card and it can be programmed for different request. Smart cards are being able to design to be inserted into a slot and read by a special reader.
Smart cards are frequently used in different applications, which need a strong safety protection and confirmation. There are two essential group of smart card are available like memory cards and microprocessor cards. The memory cards are the type of card that holds only non-volatile memory storage mechanism and can include a particular security feature. The microprocessor cards are an advanced card of memory cards. These microprocessor cards contain volatile memory and microprocessor parks and components.
Terrestrial Trunked Radio
Terrestrial Trunked Radio is known as TETRA. It was developed by the European Telecommunications Standardization Institute. By using TETRA we are benefited in many ways over in other technologies. The much lower frequency used gives longer range, which in turn allows very high levels of geographic coverage with a smaller number of transmitters, therefore cutting infrastructure costs. TETRA has a High ghostly effectiveness. The one too many group call is normally set-up within 0.5 seconds, so that TETRA have a very fast call set-up.
It also works at very high speeds and it also supports a variety of emergency calling method. The communication will ensure the success even during the overload condition because the systems have several instruments, which is intended into the protocols and radio limitations. In the absence of a network mobiles can use ‘direct mode’ whereby they can share the channels directly. TETRA offers a point-to-point function that established analogue emergency services were the radio systems did not provide this facility.
About MICROPROCESSOR
Microprocessor is a computer processor resting on a microchip. Microprocessor is known as a heart of personal computer and nearly all computer units. Microprocessor is a small chip which is known as the heart of a computer. The fundamental characteristics used in microprocessor are instruction set, bandwidth and clock speed. In instruction set the set of information’s can implement through microprocessor. The number of bits can be processed in a single instruction through bandwidth.
The clock speed decides how many instructions per second the processor can perform. The microprocessor mainly implements a set of machine instructions and then it will tell the processor what to do. The microprocessor power is measured in bits and microprocessor speed is measured in hertz. The microprocessor does all the calculations like adding, subtracting, multiplying, and dividing. Based on the instruction a microprocessor will shift the data from one memory to a new place. Microprocessor will create a decisions and jump to a new set of instructions which supports on those decisions.
Fatgamer Videogames
Video game is basically used for Entertainment. The Electronic game involves interact a user interface to provide visual effect on a video device with various display formats. Video game accessory of ps3 cases has easily access for device in and out. This platform consists from large computer to small handheld devices.

The art of video game covers are fully graphically designed as all movie posters with high quality pieces. Fatgamer video games are very easy to understand and simple to play method.
What is a Video Card
Video Cards, also known as display cards, graphics cards, graphics controllers, or graphics accelerator cards, which is used to convert binary data into display images. The video card is an extension card that agrees to the computer to send graphical information to a video display device like monitor or projector. Video card is the memory chip that stores the Video Card’s configuration data.The Video Card also has its own video BIOS chip. The video BIOS have the instructions that permit the Video Card to appropriately interface with the rest of the computer and its operating system.
A video card is naturally an adapter, which is a removable expansion card in the PC. the video adapter consists of three apparatus like video chip set, Some kind of RAM and a RAMDAC. The video chip produces the signals, which the screen must receive to form an image. Video card RAM is required to keep the entire screen image in memory. A RAMDAC chip is used for converting the signals from digital to analog form.
