1, CPU: All operations of the computer are controlled by the CPU, the CPU's performance indicators directly determines the performance of the microcomputer system indicators, the current market mainstream is the Pentium, Core i3, i5 and so on. Do software development is recommended I5 and above
2, display screen: LCD monitor is the most expensive part of a laptop. The size of the screen for the mainstream 14.1 inches, there are 15 inches, if the user often travel, it is recommended to choose some ultra-thin, ultra-lightweight laptop, the screen in the 12-inch to 13 inches, do software development is recommended to 14 inches or 15 inches, so that it looks clearer and more comfortable.
3, memory: used to temporarily store the CPU computing data, as well as data exchanged with the hard disk and other external memory, all programs in the computer are running in the memory, so the performance of the memory of the computer is very big impact. The current market mainstream is 2G/4G, as well as the size of the 8G memory, do software development is recommended more than 4G.
4, hard disk capacity: as a computer system data storage, capacity is the most important parameters of the hard disk, the main consideration of the hard disk capacity and speed, the market mainstream is 500 and 1T capacity, 5400 speed and 7200 speed.
5. The graphics card is a digital-to-analog signal conversion device for computers, undertaking the task of outputting graphics. For people engaged in professional graphic design graphics card is very important, the best graphics card is N card, the best memory 1G or more.
6, CD-ROM drive: currently popular with DVD-RW (DVD burning). From the point of view of use and economy. To pay attention to the stability of the optical drive to read the disk, read the disk sound, read the disk when the error correction ability, optical drive speed.
7, batteries and power adapters: as far as possible to buy lithium batteries, and for the power adapter, in the purchase should pay attention to after a long time working, if the temperature is too high is not normal.
8, expandability: should give full consideration to the expansion of the product performance and scalability. The most frequent use of the USB interface, there are more than one better to use, can be easily connected to a digital camera, scanner, mouse and other peripherals.
9, whether the pre-installed operating system: no pre-installed operating system, is the so-called "bare metal". This has a certain impact on the stability of the system.
10, brand: it is best not to buy a laptop just cheap, or high specification. Brand assurance in the purchase is meaningful, because the general brand image of a good company, usually in technology and maintenance services have a greater investment, and reacted to the price of the product.
