      關于電腦選購指南和購買電腦的注意事項,下面學習啦小編就從用戶需求、買臺式機還是筆記本、買品牌機還是組裝機、電腦性能指標等方面指導應該如何購買電腦,需要的朋友可以參考下

      隨著電腦的應用與普及,電腦已經逐漸成為人們學習、工作、生活中不可缺少的工具。同時,電腦的價格在逐漸下降,很多用戶開始準備選購自己的電腦。選購電腦要考慮用戶的需求、價格承受能力、商家服務質量等。

      1、明確用戶需求

      購買電腦之前,首先要確定用戶購買電腦的用途,需要電腦為其做哪些工作。只有明確了自己購買的用途,才能建立正確的選購方案。下面列舉幾種不同的計算機應用領域來介紹其各自相應的購機方案。

      (1)商務辦公類型

      對于辦公型電腦,主要用途為處理文檔、收發E-mail以及制表等,需要的電腦應該穩定。在商務辦公中,電腦能夠長時間地穩定運行非常重要。建議配置一款液晶顯示器,可以減小長時間使用電腦對人體的傷害。

      (2)家庭上網類型

      一般的家庭中,使用電腦進行上網的主要作用是瀏覽新聞、處理簡單的文字、玩一些簡單的小游戲、看看網絡視頻等,這樣用戶不必要配置高性能的電腦,選擇一臺中低端的配置就可以滿足用戶需求了。因為用戶不運行較大的軟件,感覺不到這樣配置的電腦速度慢。

      (3)圖形設計類型

      對于這樣的用戶,因為需要處理圖形色彩、亮度,圖像處理工作量大,所以要配置運算速度快、整體配置高的計算機,尤其在CPU、內存、顯卡上要求較高配置,同時應該配置CRT顯示器來達到更好的顯示效果。

      (4)娛樂游戲類型

      當前開發的游戲大都采用了三維動畫效果,所以這樣的用戶對電腦的整體性能要求更高,尤其在內存容量、CPU處理能力、顯卡技術、顯示器、聲卡等方面都有一定的要求。

      2、確定購買臺式機還是筆記本

      隨著微型計算機技術的迅速發展,筆記本電腦的價格在不斷下降,好多即將購買電腦的顧客都在考慮是購買臺式機還是筆記本。對于購買臺式機還是筆記本,應從以下幾點考慮。

      (1)應用環境

      臺式機移動不太方便,對于普通用戶或者固定辦公的用戶,可以選擇臺式機。筆記本的優點是體積小,攜帶方便,對于經常出差或移動辦公的用戶應該選購筆記本。

      (2)性能需求

      對于同一檔次的筆記本和臺式機在性能上有一定的差距,并且筆記本的可升級性較差。對有更高性能需求的用戶來說,臺式機是更好的選擇。

      (3)價格方面

      相同配置的筆記本比臺式機的價格要高一些,在性價比上,筆記本比不上臺式機。所以,對于價格因素上的選購,臺式機相對較便宜。

      3、確定購買品牌機還是組裝機

      目前,市場上臺式機主要有兩大類:一種是品牌機,另一種就是組裝機(也稱兼容機)。

      (1)品牌機

      品牌機指由具有一定規模和技術實力的計算機廠商生產,注冊商標、有獨立品牌的計算機。如IBM、聯想、戴爾、惠普等都是目前知名的品牌。品牌機出廠前經過了嚴格的性能測試,其特點是性能穩定,品質有保證,易用。

      (2)組裝機

      組裝機是電腦配件銷售商根據用戶的消費需求與購買意圖,將各種計算機配件組合在一起的計算機。組裝機的特點是計算機的配置較為靈活、升級方便、性價比略高于品牌機,也可以說,在相同的性能情況下,品牌機的價格要高一些。對于選擇品牌機還是組裝機,主要看用戶。如果用戶是一個計算機初學者,對計算機知識掌握不夠深,那么購買品牌機就是很好的選擇。如果對計算機知識很熟悉,并且打算隨時升級自己的計算機,則可以選擇組裝機。

      4、了解電腦性能指標

      對于一臺電腦來說,其性能的好壞不是由一項指標決定的,而是由各部分總體配置決定的。衡量一電腦的性能,主要看以下幾個性能指標。

      (1)CPU的運算速度

      CPU的運算速度是衡量電腦性能的一項重要指標,它通常采用主頻高低來描述,F在市場上流行的雙核CPU,在主頻速度提高的同時,采用多核技術,總體的主頻越高,運算速度就越快。

      (2)顯卡類型

      顯卡是將CPU送來的影像數據處理成顯示器可以接收的格式,再送到顯示屏上形成畫面。市場上比較流行的顯卡芯片為NVIDIA、ATI顯卡,以獨立顯卡容量大小作為衡量顯卡性能指標的尺度。目前市場上以獨顯256MB作為主流顯卡。

      (3)內存儲器容量

      內存是CPU直接訪問的存儲器,電腦中所有需要執行的程序與需要處理的數據都要先讀到內存中。內存大小反映了電腦即時存儲信息的能力,隨著操作系統的升級和應用軟件功能的不斷增多,對內存的需求容量越來越大。
