The computer is accepting input, processing according to the instructions of the input data and information of electronic equipment. There are four types of single-chip computer: marketing, and mainframes and giant computer.
Computers can solve a series of problems, and make hundreds and even thousands of times but don't feel tired logic and bored. It can be found in the small hours. The computer can be in drab, routine tasks instead of one aspect, but they have not far invasive, It according to its work instructions and are not of any value judgment. But the computer can be instantaneous makes lots of arithmetic/logic operation.
Small computer also called medium machine, is like a desk, the size of the machine processing speed and data storage capacity between single-chip and giant computer. Medium-sized companies and large company department for special purposes generally use them. For example, they can be used for research or monitor a production process. Small companies generally used for general data processing, marketing, for example.
Only in the Macintosh computer Macintosh on the run, it provides the high quality of graphical user interface, and very easy to use, Apple Macintosh system is used for Motorla 7.5 PowerPC company Apple computer design of the microprocessor in the Macintosh, it is an important milestone, they like Windows NT and OS / 2 is a powerful operating system. The System has the function of network, and 7.5 can read. Windows and OS / 2 files it has several advantages
Data communication system is through the communication line will transmit data from one place to another place in electronic system, you can use the data communication through your computer will send information to use another machine friend, you have to work in the company, its computer systems around the building, and even the world. That means, all parts - the input and output unit, the processor and storage equipment - are in different places, it is through the communication link. Or, you may use telecommunications line, line, located near the external data unit. Then you may be transferred to their information used to work on a computer.
Data communications lines can be made by two ways connection: point-to-point connections with a multipoint line. Point-to-point circuit connected directly to send and receive equipment, and a multipoint line connecting multiple devices, rather than just a sender equipment and a receiver equipment.
Satellite communication refers to using the rail communication satellites sent from a ground of one or more information to other sites. Satellite communication is communication field research, its purpose is possible price increase obtain the scope and capacity.
Data to asynchronous transfer mode. Asynchronous transfer mode in, can send and receive a year since the day that is often used method. Asynchronous transfer is often used to slow end equipment. Its advantage is sending a convenient can transmit data. Defect is relatively slow data transfer rate. Synchronous transmission used for sending a byte, or a few pieces of data transmission of information. In order to realize the data transmission, the sender and receiver with accurate section block interval to appear. Therefore, the system requires a synchronous clock. Its advantages are data can be quickly, defect is needed to send fee
Computer is follow the instructions to accept input, processing input data and generates information on the electronic equipment. There are four types of computers: microcomputers, minicomputers, mainframes and supercomputers.
The computer can solve a range of issues and has done hundreds or even thousands of times the logic to determine without feeling fatigue and boredom. It can be found in a small part of the answer. The computer can be monotonous, routine tasks instead of people, but they are not far-invasive; it in accordance with the instructions to it to work without any value judgments. But the computer can carry out a large number of instantaneous arithmetic / logic operation.
Small computer, also known as medium-sized machine, is like a desk-sized machine, their processing speed and data storage capacity ranging between the microprocessor and the supercomputer. Medium-sized companies and large companies generally use their departments for special purposes. For example, you can use them for research or monitoring of a production process. Small companies are generally the use of minicomputer for the overall data processing, such as statistics.
Macintosh Software runs only on Macintosh computers, which provides high-quality graphical user interface and very easy to use, Apple Macintosh system 7.5 is to use the Motorla the company's PowerPC microprocessor APPLE computer designed for the Mac is a an important milestone, which, like Windows NT and OS / 2 as is a powerful operating system. System 7.5 has a network function, and allowed to deliver. Windows and OS / 2 files that it has several advantages over
Data communication system is through the communication lines to send data from one place to another place electronic system, you can use the data communication through your computer send information to another machine to use a friend, you may be working for a company , its computer systems throughout a building, or even the country and the world. In other words, all the parts - the input and output units, processors and storage devices - all in different places, through communication link up. Or you may use long-distance communication lines, telephone lines, close units in the external data information. Then you may transfer the information to their computer on for the return to work and analysis.
Data communication lines can be formulated in two ways to connect: point to point and multi-point line connection. Point to point lines connected directly to send and receive equipment, while the multi-point lines to connect multiple devices, rather than a sender device and a receiver device.
Satellite communications refers to the use of communications satellites orbit from a ground station to send the information sent to another one or more of the ground station. Satellite communications is the field of communication research, which aims to obtain the lowest possible cost of increasing the scope and capacity.
Data can be asynchronous or synchronous transmission. In the asynchronous transfer mode, one can only send and receive one from the Festival and is frequently used method of microcomputers. Asynchronous transfer is also often used to slow down the final device. Its advantage is that a sender can transmit data easily. The disadvantage is the relatively slow data transfer rates. Synchronous transmission is used once to send a few bytes or data blocks a lot of information transmission. In order to achieve data transmission, the sender and recipients of sub-section block must be based on a precise time interval occurs. Therefore, the system needs a synchronous clock. Its advantage is that data can be quickly transmitted, shortcomings is necessary equipment needed for fat fees.

I Computer English bad enough, you高手帮帮忙be urgently!!!!
spring girl quietly to the campus, the campus is full of the flavor of spring. fall in. xiaocaohu secretly out from the soil, nennen, lulu's.
the bloom of the flower bed, and some fiery red, and some ruxia powder, and some white as snow. you let me, i am not you, even with open flourish. on both sides of the road as the green holly viewed from afar with the long, green leaves look at the past so bright, just like further grazed along the oil-like.
wind gently blowing, the wind brought in the grass taste, and there are various kinds of scent. birds will nest in the tree, happy to sing the song, and friends to show off their sharp voice, meet the beautiful spring.
wildflower also opened, some like small stars, some like a small gourd, some like small speakers……. scattered in the bushes, issued qinrenxinbi aroma.
you look at the pine and cypress, so cang green, charming, particularly the tasong, such as precious stones piled with the green. showing us its unique beauty.
look! our campus beautiful spring ah! as the saying goes, the good: "showing the true, seeing is believing!" you have to look at the campus this charming scenery!
