GPU - Graphic processing unit
Also called as a VPU or a visual processing unit, is a specialised electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in frame buffer intended for output to a display. GPUs are very efficient at manipulating computer graphics, and their highly parallel structure makes them more effective than genera; purpose CPUs for algorithms where processing of large blocks of data is done in parallel. It is a specialized circuit designed to accelerate the image output in a frame buffer intended for the output to a display. RAM – Random Access Memory

A random-access memory device allows data items to be read and written in roughly the same amount of time regardless of the order in which data items are accessed. Ram takes the form of integrated circuits. A portion of the computer’s hard drive is set for the paging file or a scratch partition, and the combination of physical Ram and the paying file form the system’s total memory. When the system runs lows on physical memory, it can “swap” portions of RAM to paging file to make room for the new data, as well as to read previously swapped information back into RAM. Excessive use of this mechanism results in thrashing and generally hampers overall system performance, mainly because hard drives are far slower than RAM. Software can “partition” a portion of a computer’s RAM, allowing it to act as a much faster hard drive that is called a RAM disk. A RAM disk loses the stored data when the computer is shut down, unless memory is arranged to have a standby battery source. Sometimes the contents of a relatively slow ROM chip are copied to read/write memory to allow for shorter access times. Central Processing Unit

A central processing unit is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical and input/output operations of the system. A computer can have more than one CPU, this is called multiprocessing. All modern CPUs are microprocessors, which mean it is contained to one single chip. Some integrated circuits can contain multiple CPUs on single chip; those IC’s are called multi-core processors. An IC containing a CPU can also contain peripheral devices, and other component of computer system, this is called a system on a chip. Two typical components of a CPU are the arithmetic logic unit (ALU), which performs arithmetic and logical operations, and the control unit (CU), which extracts instructions from memory and decodes and executes the, calling on the ALU when necessary. Not all computations systems rely on a central processing unit. An array processor or vector processor has multiple parallel computing elements, with no one unit considered the “centre”. Each motherboard will support only a specific type (or range) of CPU, so you must check the motherboard manufacturer's specifications before attempting to replace or upgrade a CPU in your computer. Modern CPUs also have an attached heat sink and small fan that go directly on top of the CPU to help dissipate heat. Overclocking is the process of making a computer or component operate faster than the clock frequency specified by the manufacturer by modifying system parameters (hence the name "overclocking"). Operating voltages may also be changed (increased), which can increase the speed at which operation remains stable. Most overclocking techniques increase power consumption, generating more heat, which must be dispersed if the chip is to remain operational. Storage

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. It is a core...
