HD Technology

Today’s world will not function without computers. It’s an electronic machine used for processing data. Besides that, it is also used for various multimedia purposes. The prominent among them are gaming and high definition video watching. Along with time, improvements have also increased. Today the video content delivered is very high. It includes regular video types and videos in games. This is possible due to the advancement of HD technology.

HD or high definition is a technology where the multimedia contents have a specific frequency. The term HD refers to the quality of picture. This picture quality has improved a lot. In general, a HD video or picture is the one whose resolution is very high. But most of the HD content is not delivered fully because of the lack of technology used in regular PC’s. To view a specific picture or video in HD, the PC must be equipped with a high end graphics card and a flat screen monitor. The graphics card is required since it boosts graphics based applications such as HD contents and a flat screen monitor is required for the proper display of it.

These HD contents can be properly displayed in a LCD or LED monitor. The main factor that differentiates HD content from a regular content is its pixilation. A pixel is a smallest part of an image. Larger the number of pixels, higher will be its quality. HD contents can be resized without the loss of quality.

The best example of HD is the blue ray technology. A blue ray disk is far superior to a DVD both in terms of size and content quality. The videos from a blue ray disk are called HD videos because of its high resolution and very high bitrate. Today video containers such as mkv and mp4 are used to store HD videos.

New Processors

A computer is a high tech processing machine which is used to process data that are fed through various input devices. It is also used for various other activities such as gaming, video watching, surfing the net and other fun activities. To control all these activities, the CPU has a core. This core of the CPU which processes all the input data and carries out the tasks is called a processor.

A processor is housed into the motherboard. The connections from all the other peripherals are sent to the processor so that it can control all the activities. Whenever something happens in a computer, it is done by the consent of the processor. The processor can be classified based on the word bits. It is either 32 bit or 64 bit type. A 64 bit processor is faster than a 32 bit type as it utilizes all the memory from RAM and functions much faster.

The speed of a processor can be derived from its clock speed. Higher the clock speed, faster will be its processing. The clock speed varies from 2 GHz to 3.5 GHz. The main factor affecting a processor’s speed is the cache memory. It is a small high speed memory that resides in the CPU. It ranges from 2 to 12MB. As the cache increases, the processing speed also increases. Today’s processors are also fitted with an external fan for cooling purposes.

Today Intel and Advanced micro devices or AMD are the leading manufacturers of processors. Intel’s processors are differentiated based on the class. It has total of 3 classes namely Pentium, Core and I series. Intel’s I-series is the latest of Intel’s processors and also better than the older ones. They are also differentiated based on the number of cores. They are single core, dual core and the quad core. Today Intel is using 45nm silicon technology for its processors.

Graphics Card

An electronic machine used for processing of data is called a computer. It can also be used for multitasking and multimedia applications. Multimedia applications include high definition video watching and gaming. But most of these high end applications cannot be run by a regular PC. Hence a graphics card is used. Graphics card is an accelerator tool which speeds up graphics related applications.

A graphics card also has some dedicated memory to store program data. Larger the memory of the graphics card, higher will be the speed of the graphics applications. But the most important feature of a graphics card is the number of cores or processors in it. It varies in the range of 16 to 750. Higher the number of cores, faster will be the processing. A graphics card may either be 128 bit or 256 bit. Factors such as core clock, shader clock and memory clock effects its overall speed. Higher these clock rates, the better.

A graphics card is a bus type device which is plugged in to the PCI port of the motherboard. If an additional graphics card besides the one already residing is added, the total memory of graphics adds up. Graphics card is either DDR2 or DDR3 type. The shader model of a graphics card denotes the type of content delivered. A graphics card with shader model 4 will be of top notch.

The most prominent use of graphics card is in games and playing HD video contents. For games to play smoothly, a graphics card with suitable memory and good number of cores is required. A graphics driver must be installed so that the graphics card can be detected by the system. The performance of a graphics can also be increased by over clocking it. Today NVIDIA and ATI companies are the leading providers of graphics card for PC.
