Network Support For Computer Motherboard

Posted on by blogger

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.

Telecommunication version iPhone 4 enter Zhongguan Village

GB C version iPhone 4 are 199.99 US dollars (is approximately equal to Renminbi 1320 Yuan) in the Verizon two year contract selling price, but this machine 16GB and 32GB the version iPhone 4 bare mobile phone quoted prices respectively are 649 US dollars (are approximately equal to about Renminbi 4300 Yuan) and 749 US dollars (are approximately equal to about Renminbi 4900 Yuan).

Besides replaced has set at the antenna, to match outside the newest iOS4.2.5 system, the C version and W version iPhone 4 in the hardware disposition, the contour as well as the concrete function aspect have not distinguished nearly.

Reporter in the interview found that the US just started to sell C version iPhone 4, in some electronic commerce website has many sellers to declare that may buy on behalf of another entity. Is known as may from American straight postal brand-new unopened C the version iPhone 4 seller express, 16G selling price RMB 6599 Yuan; 32G selling price RMB 7399 Yuan. The sold note demonstrated that this shop has sold nearly 30 C since February 10 version iPhone 4. Another buys on behalf of another entity the shop for several days also to sell ten remainders.

Compares in website purchasing fiery, Zhongguan Village -the parallel import- business actually indicated that C version iPhone 4 do not have the cell phone card slot in the American market, in domestic can only adopt -burns the number- the way to use, at present includes the domestic operator as well as dealer’s service side is unable to provide this service, therefore is also unable to dial normally telephones.

According to a Zhongguan Village technical personnel introduced that so-called -burns the number-, is refers to the cell phone number not to use in the cell phone card insertion cell phone, but is reads in directly the cell phone (cell phone accessories cheap). Burns the number way to divide into two kinds generally: First, the operator provides burns the number service; second, invites a person generation of fever, the latter sees in Net shop, has certain risk.

The above parallel import business tells “Every day Economic news” reporter, the source of goods question is not difficult to solve, US’s long-term partner was very easy to find, whether to burn the number as for this cell phone to suit the Chinese user use (cheap phone accessories), now domestic still did not have the precedent, -the present US goes on the market C version iPhone 4 have not possibly been able to use the telecommunication network directly, the related software was also unstable, whether to stock with goods also waits for observing-.from: cellular phone accessories

Fiber Optics Explained For The Rest Of Us

Posted on by blogger

The Principle of fiber optics is based on transmission of data by means of light. Concept of fiber optics was first conceived by Claude Chappe in 1790’s. His idea for fiber optics was based on an optical telegraph concept invented by Graham Bell also tried the means to send information by the atmosphere but did not succeed. Finally, fiber optics emerged with the onset of new era based on the principle of total internal reflection which is a distinct quality of light rays.

Fiber optics emerged and grew into more advanced phase due to requirement from radio and telephone engineers. These engineers required more bandwidth for data transmission. Thus these engineers had been looking out for a medium to transmit data in more reliable and faster form rather than copper cables. They also wanted to avoid the hazards of electric shocks and interference which were a constant problem of copper cables.

Fiber optics had attracted some attention because they were analogous in theory to plastic dielectric waveguides used in certain microwave applications. Finally a technology evolved that used glass or plastic threads to transmit data. Cables involved in fiber optics contain several bundles of glass threads which are capable of transmitting data in modulated form.

With the onset of fiber optics and fiber optic cables data started to transfer faster as fiber optic cables have greater bandwidth than metal cables and are more resistant to external interference. Lighter and thinner fiber optic cables readily transfer data in digital form rather than analogue form. This technology is most useful in computer industry which now forms an integral part of telephone, radio and television industry.

Telecommunications applications of fiber optics use flexible low-loss fibers, using a single fiber per optical path. Along with the communication industry fiber optics plays an important role in medical and industrial applications also. Many medical appliances like endoscope use the principle of fiber optics. Industrial applications viz. in television industry use the principle of fiber optics to obtain flattened images in cathode ray tubes.

Fiber optics yield distortion free data transmission in digital form. The audio waves transmitted via principle of fiber optics deliver accurate signal transfer. Fiber optics is also useful in automotive and transportation industry. Traffic lights, organized and scrutinized highway traffic control, automated toll booths, etc. are some of the benefits of application of fiber options in the transportation mechanism.

Cable TV companies and Internet Service Providers equivocally find fiber optics indispensable in their industry. Fiber optics provides tamper free, high bandwidth and larger data carrying capacity to the service providers. This eventually leads to better consumer satisfaction.

Unlike copper wire system fiber optics do not use and electrical form to carry data. The use of light gives a competitive edge to fiber optics over regular data transmission options. But eventually use of fiber optics is very expensive as compared to copper cabling system.

Large-scale Telecom Mergers Will Appear

Posted on by blogger

There are already clear signs that mergers and acquisitions of the telecommunications industry may rise steadily in 2011 and 2012. Some operators have announced plans to conduct large-scale transactions.

In 2008, before the growth of the global economy slowed down, the telecommunications industry has been in the pursuit of large-scale mergers and acquisitions. But in the subsequent two years, operators set aside most of the transaction to focus on addressing the economic crisis. However, after the two years of the quiet period, many telecom operators become saturated in the development of its domestic market users. In the fierce competition they begin to continue their former growth plans.

They have recognized the limited opportunities to enter new markets. New potential opportunities and the single market opportunities are few. By the merger they will be able to achieve their goals. Therefore, the trading activity of the telecommunications industry may again become active. The next wave of M & A wave is likely to be the industry’s consolidation.

Compared with other industries, the telecommunications industry remains very fragmented. The income of the largest operator accounts for only a small part of the total industry revenue, indicating that this area is in the golden age of further consolidation.

In the new round of growth period, the re-shuffle merger of the telecommunications industry includes three types: first, the large-scale cross-border trading is expected to become the mainstream. Operators who can take the opportunity to take advantage of this integration is expected to become the winner of the global telecommunications industry. They will also have sufficient financial resources and strong organization, including management, business structure, processes, etc.

Second, the merger may be at the market level, including the business combination of the same market. Operators will look for opportunities to acquire the existing business of a competitor, merge competitive organizations. Although this form is not as popular as cross-market integration, it allows operators to increase the number of users, fight for greater market share and eliminate direct competitors at the same time. Finally, the third kind of merger will appear within the operators.

In the short term, carriers will be possible to achieve recovery and accelerate growth through the three types of merger. However, the operator inter-group cross-market mergers and acquisitions may reshape the telecommunications industry. The analysis also showed that cross-market integration is in a upward momentum, while the opportunities of market integration at the same level will gradually decrease.
