【正文】 業(yè)在一個園區(qū)內(nèi)具有多處辦公地點(diǎn)，樓宇間網(wǎng)絡(luò)的連接距離通常大于 100 米，所以需要采用光纖進(jìn)行布線。許多小型企業(yè)網(wǎng)絡(luò)技術(shù)人員較少，而對網(wǎng)絡(luò)的依賴性卻很高，因此需要網(wǎng)絡(luò)盡可能簡單、可靠、易用，降低網(wǎng)絡(luò)的使用和維護(hù)成本顯得尤 為重要。從廣義的角度，又可以將同等規(guī)模的政府、科研及教育等單位也作為小型企業(yè)來看待。雖然企業(yè)網(wǎng)絡(luò)不僅 可以提供給我們一個現(xiàn)代化的高效，快捷，安 全的辦公環(huán)境，還可以進(jìn)行高速的數(shù)據(jù)傳輸和實(shí)現(xiàn)生產(chǎn)自動化。這直接關(guān)系到企業(yè)能否獲得關(guān)鍵的競爭優(yōu)勢。 Small and mediumsized enterprises； puter works
