本書嚴格按照最新《全國碩士研究生招生考試計算機學科專業(yè)基礎考試大綱》(簡稱“考試大綱”)的計算機網(wǎng)絡部分的要求,以考研指定教材最新版——《計算機網(wǎng)絡(第8 版)》(謝希仁編著)為藍本,對考試大綱所涉及的知識點進行梳理和提煉,力求內容精練、重點突出,主要包括計算機網(wǎng)絡體系結構、物理層、數(shù)據(jù)鏈路層、網(wǎng)絡層、傳輸層、應用層等內容。同時,本書從2009—2022 年全國碩士研究生招生考試(簡稱“全國聯(lián)考”)計算機學科專業(yè)基礎試題的計算機網(wǎng)絡部分中精選真題,按照考查知識點、難易程度將其分門別類地安排在對應的章節(jié)中,并給出答案和詳細解析;除此之外,為提高學習效率,與真題互為補充,本書還設置了“解題指導”“重難點答疑”“精選習題”“精選習題參考答案”版塊,并在例題解析的過程中有針對性地歸納知識點,指出重點、難點與容易出現(xiàn)的問題,從而實現(xiàn)講練結合,為考生復習備考提供強有力的支持。本書可供參加計算機學科全國聯(lián)考的考生作為復習用書,也可作為計算機相關專業(yè)學生學習“計算機網(wǎng)絡”課程的參考用書。
