Computer Processors

A processor is an electronic circuit that can run computer programs. Computer hardware consists of various components connect to microprocessors, specifically, the computer's central processing unit (CPU), the electronic circuit that control the process of computer. The input and output hardware interaction is controlled by software called Basic Input Output System software (BIOS). A microprocessor containing all of the functions of a central processing unit (CPU) on a single integrated circuit (IC). Computer processors were constructed out of small and medium-scale IC's which contains hundred transistors. Therefore, one or more microprocessor as processing element from the smallest devices to the largest mainframes and supercomputers. The operation of processors is to execute a sequence of stored instructions called a program. A program is stored in a storage device such as floppy disk, hard disk, and CD-ROM drive. The program is working from the main memory of the computer, which is known as (RAM) random access memory.

The function of a CPU is same as calculator, only much more complex and powerful. So, there are four steps that all CPUs use in their operation that is fetch, decode, execute, and write back. The type of the processor can be a very important consideration for users who are building a computer. Today, mostly used processor is Intel.

Central Computer (Hubs)

Computer networks are working well with most common components on a network, not counting cables, "routers", "hubs", and "switches". A network hub is a simple broadcast device that do not manage any of the traffic that comes through them. The new generation network hardware operates on the "Open System Interconnection" (OSI) standard. OSI standard defines how communications is possible on a network and how should be implemented. Therefore, a message is sent between computers, then its broken into parts. First base level, is the message in form of "1" and "0" bits. Second level is a group of bits called a "frame".Third level is a group of frames called a "packet". Therefore ,the network hub works on the first layer of the OSI standard, called the "physical layer". Computer hardware containing different parts which are visible to us like keyboard, printer and cables etc...The different generation are take place as going from first generation to fourth generation, therefore hardware technology is increase.

The hub is the most simple of the three modules. A hub is not aware of the contents of the message that is processed just handles the message as bits. It simply records the signal, and rebroadcast it to all. Two type of hubs are there active and passive. An "active" hub will clean the electrical signal of noise before sending. A "passive" hub provides the signal as received to each port. Mostly hubs are used to link multiple computers with a printer.

Computer Audio Tutorial

Computer audio is the basis of digital audio. All audio that is recorded or played through a computer system is digital, but all audio that is played out of a speaker system is analog. Computer Music and Digital Audio Series has a dealing with music, audio, computers and digital technology. A digital audio workstation (DAW) is an electronic system. Basically , this is designed to record, edit and play back digital audio. One advantages is that you can manipulate recorded sounds. A specialized audio converter unit is there which performs some variety of analog-to-digital (ADC) and/or digital-to-analog (DAC) signal conversion. Analog audio uses information to try and best reproduce the original sound waves from the source. This can produce a very good recording , but these recording is between connections and generations of recordings. Therefore, Digital recording takes samples of the sound waves and records it as a series of bits ( 1s and 0s) that best the wave pattern. So, the quality of the digital recording will based on the bits and samples used for the recording. You can Browse through our website for more information on related product.

The bits and K Hz refer to the sample rate and audio definition that a digital recording can have. There are various standards used for digital audio:-

  • CD -Audio 16-bit 44KHz

  • DVD -16-bit 96KHz

  • DVD - Audio 24-bit 192KHz

Basically, the bit-rate defines the number of bits used in the recording to determine the amplitude of the sound wave at each sample. Hence, it is best to look for one capable of 16-bit 96KHz sample rates.
