Hardware Components of Computer

Hardware components of computer is also called constituent parts in terminology of computer science. The most of people are good at applying computer software for work or playing game, but they seldom think about about components of computer. How is the personal computer constituted? Perhaps, these basic knowledge may help you to save a lot of cost when you repair it. Let us have a look about each hardware component.

Main Frame

The computer components commonly placed in the chassis are commonly referred to as “mainframe”. It is the most important part of the computer, and the main components, such as motherboard, CPU and hard disk, are in the mainframe.


The full name of CPU is the “central processing unit”, which is made of a gilded material. Its function in PC can be said to be equivalent to the role of the brain in the human body. All computer programs are run by it.


The motherboard is also called main-Board. It is actually a circuit board, all of which are all kinds of circuits. It can be said that the nervous system of the PC, meanwhile CPU, memory, display card, sound card and so on are directly installed on the motherboard, and hard disk, floppy drive and other components also need to be connected through the wiring to motherboard.


Compared with external memory such as disk, memory refers to the internal memory that CPU can read directly, mainly in the form of chips. Memory is also called “main store”. Memory chips are commonly seen as strip, also known as “RAM which need to be inserted in the memory slot on the motherboard to work. Another kind of memory is called “cache”, which is usually built into the CPU or motherboard.

Graphic Card

The graphic card (Display Card) is an important component connecting the monitor and the PC motherboard. It is inserted in the expansion slot on the motherboard. It is mainly responsible for converting (decoding) the display signals sent by the mainframe to general electrical signals, so that the display can understand what the PC is doing with it. The display cards also have memory, called “Display Memory” which will directly affect the display effects according to memory size, such as definition and color richness and so on.

According to statement of director of Onespace, every key points such as blasting off, separation of fairing and satellite rocket separation are all challenges and test.


The carrier rocket launched by this time carried three of cubic satellites. After entering the predetermined orbit, the rocket releases two of cubic satellites in turn, then entering the sub-orbit for flight test and one satellite had completed the recovery of parachute landing. This launch is also the first launch of the “one rocket, multi satellites” mission by China’s private commercial aerospace enterprises.


With the rapid development of space exploration technology companies in the United States, especially their rockets and cargo spacecraft undertook the relevant tasks of NASA and the International Space Station. Commercial space companies, especially private space companies participating in space launches, which is becoming a major development trend in the global space field.

Jose Mourinho and Paul Labile Pogba

Jose Mourinho’s confrontation with Paul Pogba came to the fore, and Mourinho publicly stripped the French mid-fielder of his role as deputy captain, while Paul Pogba made it clear that he wanted to go to Barcelona. Daily Mail reporters have debated who will leave Manchester United first between Pogba and Mourinho, the most of people will favor Jose Mourinho’s departure because of his poor record recently.

Opinion from JACK GAUGHAN

As things go on, both of them may leave Manchester United, but Jose Mourinho’s situation is more critical. He has not been able to lead the team to a consistent and good performance. No matter what you think of Paul Pogba, not being able to score at Old Trafford can be an overwhelming problem. Woodward certainly wants to keep Pogba as long as possible, but it’s still not clear how far he can go.



Paul Pogba is a disaster, obviously a black sheep, he has always been like this however Jose Mourinho is also the same.


A key difference is that Manchester United may still believe that Pogba has potential and value to make use of. If the Frenchman wants to transfer because of Mourinho, then things may change. If Paul Mourinho choose to go and Pogba are willing to stay, then Manchester United must want to keep the world-class player because there are not many such players at Manchester United team.



It was a regrettable period for Manchester United, with the manager setting a negative tone, starting with the messy preparation period of season.


Paul Pogba couldn’t go anywhere until January, so he is sure to stay at Old Trafford for at least three months. Jose Mourinho, however, is likely to leave before Christmas, and if that happens, it won’t be a surprise now.



Barcelona team needs Pogba and Pogba wants to go to Barcelona, all signs point to his departure. But there’s a long way to go before the January transfer or the deal doesn’t happen until summer. But before Manchester United has the chance to sell Pogba, the bad match’s result might have Mourinho leave from team earlier.

Different from CHRIS WHEELER

Pogba has made clear to Manchester United that he wants to transfer to Barcelona no matter who is the manager. Despite the breakdown of Pogba’s relationship with Mourinho, this is not the main reason he wants to leave Manchester United and the club knows it.

The Elements Effecting the Development of E-commerce

  1. The industry and geographical development are uneven.

From the view of geographical distribution, e-commerce enterprises are mostly concentrated in economically developed regions, and based on the distribution of the industry, the proportion of the industrial sector is unsufficient, the proportion of the consumer goods industry is relatively high.

  1. SMEs’ perception of e-commerce is still shallow.

In China’s e-commerce market, the biggest problem currently exists is that SMEs have a low awareness of e-commerce. At present, only 42.6% of SMEs use e-commerce services, and there is a lot of room for development. Although under the influence of the financial crisis, some small and medium-sized enterprises began to realize the benefits of e-commerce and try to use e-commerce services, but most of the SMEs are still in a wait-and-see state, and their understanding of e-commerce is still shallow.

Therefore, both the government and enterprises need to do a good job in market cultivation, increase publicity, and do a good job in guiding and cultivating enterprises to participate in e-commerce, and enhance their confidence in e-commerce.

  1. Lacking e-commerce talents in SMEs.

At present, China’s e-commerce industry lacks experienced e-commerce talents, especially SMEs have great obstacles in absorbing talents. The promotion mode of e-commerce is different from the traditional mode of SMEs. SMEs have accustomed to the original traditional sales model, and need to change the original sales model when using e-commerce for promotion. Therefore, e-commerce operators need to help SMEs in talent development.

  1. Traditional industry and e-commerce are not very well integrated.

The rapid development of e-commerce is the most important change in the business field in the past two years, and it has also had an important impact on traditional commercial. In the future, these two commercial channels are converged or competing with each other, this is worthy of discussion by the industry. However, in the foreseeable future, the two channels will follow their respective logic. E-commerce covers a wide area, products can be put on the shelves indefinitely, reducing the rents of shops, warehousing and logistics, etc., and there are certain advantages in cost. The traditional offline resources can provide better design, better visual effects, enhance the shopping experience, increase consumer confidence, enhance brand value and so on. Competition is obviously not the result that the government wants to see, so it is very difficult to promote e-commerce to integrate with traditional industries.

The History of The Great Wall

The Great Wall, is a military defense project in ancient China. It is tall, sturdy and continuous and it is used to limit enemy riding. The Great Wall is not a purely isolated city wall, but a defense system that combines a city wall as the main body and a large number of cities, barriers, pavilions, and standards.

The history of the construction of the Great Wall can be traced back to the Western Zhou period. The famous allusion of the sacred princes of the capital, Xijing (now Xi’an, Shanxi) originated here. During the Spring period, the Autumn Period and the Warring States Period, the countries competed for hegemony and defended each other. The Great Wall built into the first climax, but the length of construction was relatively short. After Qin unified the six countries to unify the world, Qin Shihuang connected and repaired the Great Wall of the Warring States, and was known as the Great Wall. The Ming Dynasty was the last dynasty to overhaul the Great Wall. The Great Wall that people saw today is mostly built at this time. The Great Wall resources are mainly distributed in 15 provinces, autonomous regions, such as Hebei, Beijing, Tianjin, Shanxi, Gansu, Inner Mongolia, Heilongjiang, Jilin, Liaoning, Shandong, Henan, Qinghai, Ningxia and Xinjiang. During the period, Shaanxi Province was with the richest resources in China’s Great Wall. The length of the Great Wall in China was 1,838 kilometers. According to the results of the National Great Wall Resources Survey of the Cultural Relics and Mapping Department, the total length of the Ming Great Wall is 8851.8 kilometers, and the Qin and Han Great Walls exceed 10,000 kilometers, with a total length of more than 21,000 kilometers.

Why we built the Great Wall at that time? In order to prevent the invasion of northern nomads, several countries in the north of the Warring States period, Yan, Zhao, Qin, etc., they have all repaired the Great Wall. After Qin Shihuang unified the six countries, they connected these great cities and built the world-famous Great Wall. In order to prevent the northern Mongolian attacking, the Great Wall was rebuilt. The Great Wall is a great miracle created by the working people of ancient China and a testimony to China’s long history. In December 1987, the Great Wall was listed as a World Heritage Site.

Build A House for the family

To build a house for the family is always the dream of us. The most people expect to own a house belonging to own with family members. Warnth, comfort and content around the whole family should be one kinds of pursuit after busy time in office, work overtime often, commute in time everyday and so many chaos and trouble matters. We may save enough money to build a house for the family then completely satisfy own wish or dream. These all are worthy but how to build a house with regular methods? Certainly, no matter how, the basic requirement as quality is important such as stainless steel nail is much better than iron nail. So materials choice should be from qualified suppliers or online great B2B trade platform. Today we will discuss about this topic below,

Good Site Choice

Actually as the simple and first method, finding a site is always to make the most of people to feel headache. Because we have to consider many factors.

  • Ground Stability

This is important thing to be cared by you because the not stable ground will ruin your warm house as high rate. So normally we avoid to build the house on the ground with mucky soil, shifting sand or so on. Perhaps some contractors may consider to pile on this kinds of ground, but I suggest stable ground is always your best choice.

  • Natural Conditions

Climate always influences your life environment, normally we will choose the site far away the area with flood, hurricane, Tsunami and some other disasters to be happened usually. This is main reason that prevent more harm for residents.

  • Nearby Conditions

Normally we would like to choose the area with convenient facilities such as police station, good quality schools, supermarket for shopping and some good restaurants to taste savory foods, certainly, hospital or clinic is also considered.

Building Foundation

  • Excavation for The Plot

Related building workers have to survey the dimension of the foundation, then stake and prepare pile around the foundation.

  • Concrete Preparation

After the foundation and pile are ready, then as the second method, we need to pour the concrete into the foundation. Normally it will bear some weight, and concrete area should be wider than the wall of foundation such as the perimeter of house to distinguish ground and home.

  • Building lines and Floors

Workers have to prepare batter boards, corner stakes for each corner of the foundation. To Make sure the build lines are level and square, then to check by measuring corner to corner. Certainly, for floors, you may choose “pier and bean” or “slab on grade”.

Walls And Roof

The basic needs are housewrap, lumber, nails, adhesives and felt paper. After that, Carpenters will get ready to frame the house wall including ceiling, floor and roof skeleton. The next method is for install the doors, windows or maybe skylight as need after wall and roof frame has been built.
