Microphone

What is Microphone?

A Microphone is an input device used for recording a audio in a computer. However, to do this you also need a sound card installed in your computer. A sound card converts an analog sound signal to a digital form and a digital sound signal to its analog form. The Microphone are mainly use in many areas such as concert halls, radio broadcasting, television broadcasting, telephones, sound recording, hearing aids, public events and in computer used for voice recording, speech recognition and VoIP.  There are also types in this such that dynamic microphones, condenser microphones and contact microphones.  First dynamic microphones is uses a magnetic field with a suspended coil of wire . Second condenser microphones is uses a capacitor plate with vibrating diaphragm. Third contact microphones are uses a piezoelectric with a crystal. 

A Dynamic Mics is used in Studio to produce all kind of sounds. It is insensitive which perfects for loud sounds. It is the unidirectional pattern or cardioids pattern because it cancels out all the unwanted sounds and pick ups a pointed direction sound. A Condenser Mics are the cousins of dynamic mics. It is more sensitive because of that it makes a softer and brighter sounds. It is very powerful comparing to the studio microphone. To pick up making them sound less muffled a top end bump of a condenser gives extra air than the dynamic would. A contact Mics, it senses audio vibrations by contacting with solid objects. It uses a piezo material to create a sound. It amplify sound from acoustic musical instruments such as violins, pianos, guitars, etc,.

Interconnecting Devices

Interconnecting Devices An Interconnecting devices is a network device. It used to transfer data from one computer to other computer with the help of network devices. There are five categories of interconnecting devices are such as. Router  Hubs  Switches/Bridge  Repeater  BRouter Repeater: Now I am going to tell you the repeater is an electronic device that used to receive and send a signal. It amplifies the signal and noise. It provides transmission of the signal.  HUB (Hyper User Bus):  In this, it used to link several computers in the same network. It based on broadcasting, and it sends the data to all computers and repeats the signal which receives a signal from one port and copies to other port and traffic are high. Bridge / Switch:  In this, we can see the interconnecting devices which can divide a single network into two or more segment are called Bridge / Switch.  It has multiple ports like 2, 4, 16, and 32. The Switch main...

Printer

What is Printer? Another widely used output device is a printer and it is a computer peripheral device. A printer produces a hard copy of a processed text or a result. A hard copy refers to a permanent human-readable text or graphics taken on physical print media such as paper or transparency. A printer will use toner to provide a quality print on paper, a toner is a replaceable material. Once the toner gets empty we can refill it and reuse it.  Most of the printers are used for commercial purposes such as private offices, industries, government offices, photo studios, etc,. Most of the printers are used to print emails, documents, files, images, color photos, color documents, color posts, banners, advertisement posters, etc,. There are the following 5 types of printers such as dot matrix printer, inkjet printer, laser printer, dye-sublimation printer, and plotter printer this are all the printer which uses nowadays for a printing purpose. A printer is characterized by the followin...

CMOS

What is CMOS? CMOS stands for Complimentary Metal Oxide Semi-Conductor and it stores roughly 64Kb of data. It is the part of the southbridge in most computers. The specification stored in Complimentary Metal Oxide Semi-Conductor must match hardware and it allows you to access the BIOS. When hardware is change or update, Complimentary Metal Oxide Semi-Conductor must be updated. CMOS Battery Accessing BIOS through CMOS setup Complimentary Metal Oxide Semi-Conductor can only be accessed when the PC is booting and key combination at start-up. The changes are stores on an NVRAM Complimentary Metal Oxide Semi-Conductor chip. The mouse doesn’t work in Complimentary Metal Oxide Semi-Conductor setup. AMI and AWARD BIOS – DEL key  PHOENIX BIOS – CTRL, ALT and ESC keys or F2        CMOS Chip Complimentary Metal Oxide Semi-Conductor is stored in an SRAM chip called Non-Volatile Random Access Memory (NVRAM). It stores data that is uses by the BIOS and NVRAM is powered by Com...
