计算机相关英语论文题目

专升本要考的科目是：英语（满分一百分），计算机文化基础（满分一百分），教育学，心理学，写作，古代汉语，现代汉语，文学概论。专升本成功的关键在于英语和计算机文化基础。英语：其实绝大数的专科生的英语都挺差的（我英语也挺差的），所以出题人也要考虑到考生的水平，因此你也不用怕英语，只要认真学就行了，多找些题练练，你也可以用英语三四级的题。专升本的英语考试比三级难、比四级容易。就算专升本时英语考难了，不是只有你一个人考的差，别人考的也差！记得当初考英语时，我考场里有个女生不会做，就急哭了。计算机文化基础：你就拿着中国石油大学出版社出版的《计算机文化基础》进行复习行了，复习时一定要全面，也是要多做练习、多看书，我当初一共看了三四遍书，看完一章，就作一章相应的专项练习，看完书后，就做综合练习，在专升本前的最后一个月，就做历年的真题和模拟题。至于专业课，你就用你自己学校发的书就行了，各个版本的书的内容都一样，没必要为了专业课再去买书。

Information literacy Knowing how to find data from several sources, select relevant material, analyse and organise it into a form that can be used to make Computers have become the tools people use to access and manage Information technologists are people who analyse and design the What is a computer? Tradition definitions of computers include • A machine that accepts data and processes it into use • A computer is a binary, digital, electronic, stored program • While a computer is commonly a digital machine, analogue machine do An electronic device, operating under the control of instructions stored in its own memory unit, that can accept data (input), process data arithmetically and logically, produce results (output) from the processing and stores results for future Many computers receive and send data (communicate) across networks LAN and W A computer system consists of hardware and What is hardware? Hardware Hardware is physical devices or components that can be physically handled – you can thou Input Devices Input devices convert data that humans collect into coded electrical signals that a computer can The central processing unit The electronic processing takes place in the CPU The CPU consists of • A control unit that controls all of the computer’s functions and an • Arithmetic and logical unit (ALU) that performs any calculation Memory Memory holds all programs and What is RAM currently open? Data (notes) Word processor OS Output devices Output devices convert the computer’s electronic signals back into information Secondary storage devices These devices store programs and data The programs and data are not necessarily (or likely to be) in current E DVD CD Communication devices These devices enable a computer to connect to another List the six different type of hardware?
