把下列英文句子翻译成中文

(1)A computer is afast and accurate symbol processing system. It can accept, store, process dataand produce output results.

(2) They containhardware components for input, central processing unit and output.

(3)Everycomputer stores numbers, letters, and other characters in a coded form. Everycharacter in the storage is represented by a string of 0s and 1s, the onlydigits founded in the binary numbering system. 

(4)Oncethe power of a computer is turned on, all the behaviors are under the controlof CPU.

(5)Primarymemory is known as random access memory (RAM) and simple named memory. It isthe storage area within the computer that holds programs and data duringprocessing. Memory is only temporary storage area; when processing is complete,memory is cleared.

(6)Generallysoftware can be divided into three types: system software, application softwareand support software, system software monitors and controls the system'shardware. Application software performs specific tasks for the user. Supportsoftware is a series of software, which support development and maintenance ofother software.

(7)Ingeneral, the characters, phases and their syntax rules for programming aregenerally called “programming language”.

(8)Programminglanguages are divided into three types: machine language, which is also calledan instruction system, is the only one used directly by computers. Theassembler language is a kind of symbolic language. It adopted some mnemonicsymbols which can show the instructional functions to present the content ofthe program. The high-level language is a programming language based onEnglish. Its operators and expressions are similar to ordinary mathematicalformulas.

(9)Objectoriented programming (OOP) is a new way of approaching the job of programmingthat differs from traditional programming because it uses objects as datastructures to enhance productivity, simplify programming, get reusability andimprove software reliability. All object oriented programming languages havethree characteristics in common: objects, polymorphism and inheritance.

(10)Objectis a data structure that contains both structured information and relatedoperations. An object can contain other objects.
