Network Support For Computer Motherboard

Network Support For Computer Motherboard

In any type of computer, motherboard is the main component, which holds many vital parts of the system and provides connections to other peripherals. It acts as a communication highway. Each part of the computer system communicates to each other through the motherboard. The objective of the motherboard is provide a communication channel to all other peripherals and parts of the computer system.

Brief History Of Motherboard
In the earlier times when computer was first invented, the device used to be built in a frame or a case with parts connected through a backplane. The backplane comprised a set of slots interconnected through wires. After the arrival of printed circuit boards, the central processing unit, read only memory, random access memory, peripherals were mounted on the PCBs. As time passed by in the 1970s and 1980s, more and more numbers of components started getting housed on the motherboard due to economical reasons. In the 1990s, the motherboards became capable of performing video,audio,networking and graphics functions.

Overview Of Motherboard
Generally a computer motherboard has microprocessor, main memory and other vital components, mounted on it. Other parts like video and sound controllers, external storage and peripheral devices are connected to motherboards through plug-in cards. In the latest motherboards, all these components are mounted directly.

Motherboard Chipset
One of the most important component of motherboard is chipset. It controls the data flow through the data bus of the motherboard.

Channelizing the data to the correct component is the primary objective of the chipset.

Motherboard Components
The motherboard contains connectors for all components. Expansion slots for PCI,ISA,AGP,DIMM and external connections for serial and parallel ports,USB ports,sound card,keyboard and mouse are mounted on it.

Keyboard & Mouse Connectors
All computers have keyboard ports connected to the motherboard. Two most commonly used connector types are DIN and AT. Nowadays mini DIN PS/2types of connectors are replacing ST types of connectors. PS/2 style sockets could be used with AT types by using a converter. USB connectors are also found in some PCs.

Parallel Port
Parallel ports are used by printers. On parallel port, multiple wires are used for carrying data signals. A 25 pin female DB connector is used in parallel port. Motherboards directly support parallel ports through direct connection or dongle.

Central Processing Unit
The component is also known as CPU. It controls all operations that are performed inside a computer. CPUs are basically large scale integrated circuits in rectangular small packages with multiple connecting pins. CPU consists of mainly two components,namely Arithmetic Logical Unit(ALU) and Control Unit(CU). ALU performs arithmetic and logical operations and CU fetches instructions from memory and execute them.

Universal Serial Bus
Universal Serial Bus or USB is an industry standard connection for PC. The speed of USB 3.0, the latest standard of USB, is 5 Gbits/second.

Basic Input Output System- Read Only Memory(BIOS ROM)
The BIOS ROM chip, which is a permanent memory,contains the software program which performs the basic operations when the computer is switched on. When the computer is powered up, the microprocessor searches for basic diagnostic information in BIOS ROM., such as, how much memory is available, whether all peripherals are working properly, if an external drive is connected,etc. When diagnostic information is found to  be OK, then only the computer starts its operation.

Random Access Memory(RAM)
RAM is a temporary memory. It is used to store data when computer is powered up.  Once the computer is switched off, this memory id erased.

Electrically Erasable Programmable Read Only Memory(EEPROM)
EEPROM is erasable programmable read only memory. It is possible to read from and write to this type of memory. Once the computer is switched off, data stored in EEPROM is retained.

Slots
Generally two types of slots are available on motherboard, namely AGP slots and PCI slots. AGP slots are used for graphics cards, while devices like modems, network cards and sound cards use PCI slots.

IDE Connector
This connector is used for connecting hard disks, CD and DVD.

Floppy Connector
The computer’s floppy drive is connected through this connector.

PC Support
Since motherboard contains so many components, any defective component could make the computer nonfunctional. Many online network support providers are rendering round the clock support for motherboards. In case the user faces any problem related to motherboard, immediately the help of PC support providers should be sought to mitigate the problem.

PC Support For Computer Networks

PC Support For Computer Networks

It will not be an exaggeration  to say that information is one of the most important issues for any business. Dissemination of the data  to the concerned people is equally vital. Computer networking came into being to make the communication between the computers faster and easier. It not only provides faster communication, but also enabled the users to to access remote programs and remote databases of the same enterprise or other organizations.

Apart from this, there are other reasons also to employ computer networking. Through computer networking, cost could be reduced by sharing hardware and software resources and by downsizing to microcomputer-based networks instead of using mainframes. Gathering information from multiple resources has become easier, which ensures the reliability of the  data.

As per definition, computer networking is nothing but the process of connecting multiple computers for the communication purpose so that information as well as resources could be shared by all connected devices.

Categorization of computer networks could be done based on vast range of characteristics like medium used for communication, scale, networking topology used,communication protocol,etc.

Mediums used by computer networks
For communication between two devices, a medium is must. There are several mediums, such as  electrical cable, optical fiber and radio waves which are used for networking. Electrical and optical fiber are used in wired technology while radio waves are employed in wireless technology.

Wired Networks
In the wired technology, twisted pair cable is the most commonly used medium for communication.

Twisted pair wire is made of metal wire that are twisted into pairs. Computer networking wire contains 4 pairs of metal wires, which are used for data as well as voice transmission. The purpose of using twisted wires is to minimize noise which is caused by electromagnetic induction and crosstalk. There are two pairs of twisted wires,namely Unshielded Twisted Pair and Shielded Twisted Pair. The speed range of twisted pair cable is 2 million bits per second to 10 billion bits per second.

Another widely used medium in wired technology is coaxial cable. It is mostly used for local area networks, cable television systems,etc. It is made of metal wire, covered with insulating layer of a flexible material with a high dielectric constant, all of which are wrapped by a conductive layer. The purpose of using insulating layer is to minimize noise and signal distortion.
Optical fiber is the another communication medium, invented in the second half of twentieth century. Its components are filaments of glass fiber covered in protective layers that transmits data by means of pulses of light. It carries light signals over long distances. Electromagnetic interferences cannot affect the signals carried by it. Its maximum transmission speed  could touch trillions of bits per second.
For all types of cable malfunctioning, network support is provided by many service providers.

Wireless Networks
There are several widely used wireless technologies, such as Wireless LAN Technology,Communication Satellite Technology, Infrared Communication Technology,Terrestrial Microwave Technology,etc.

Wireless LAN Technology employs hi frequency technology, which is akin to digital cellular and low frequency radio technology. This  spread spectrum technology connects multiple devices in a limited area. Wireless LAN in an office or home could be easily set up with the help of numerous PC support providers.

Communication satellites  utilizes microwave radio signals as communication medium because  microwave radio signals are least affected by earth’s atmosphere. Data,voice and TV signals are transmitted and received using  microwave radio technology.

Infrared Communication Technology is used to transmit signals between devices within short distance. The maximum distance covered by this technology is typically 10 meters.

Terrestrial Microwave Technology employs low gigahertz signal range, that restricts transmissions to line of sight. The maximum distance between microwave signal relay stations is 48km.

Wireless computer network is the backbone of business and technological processes, which could be immensely damaged if the networking system breaks down. In that eventuality, online PC support should be used to set the networking system right.
