The computer configuration requirements of the software engineering major are as follows:

The software engineering major involves programming languages, databases, software development tools, system platforms, standards, design patterns, etc. At the same time, almost all industries have computer software applications, and general programming has relatively high requirements on CPU and hard disk.

1. Operating system: windows?7 (64-bit).

2. Memory: 4GB (and above).

3. Graphics card: video memory 1G and above, bit width 256 bit and above, video memory type DDR3 or above (such as: NVIDIA Quadro series, ATI FireGL series or Firepro series).

4. CPU: Intel dual-core high frequency 64bit. It is recommended to use i5 series or i7 series. It is recommended that the CPU frequency is higher than 2.8GHz. The central processor must support SSE2 (Streaming SIMD Extensions 2).

5. Hard disk: no less than 7200 rpm.

6. Software: Office 2007 or 2010.

7. Monitor: resolution not less than 1400X900.

Purchase notes:

1. Clarify your needs

Before purchasing a computer, you must first determine the purpose of the computer. , what work does the computer need to do for it? Only by clarifying the purpose of your purchase can you establish a correct purchasing plan. The following lists several different computer application fields to introduce their corresponding purchase plans.

(1) Business office type

For office computers, the main purposes are document processing, sending and receiving emails, and tabulation, etc. The required computer should be stable. In business offices, it is very important for computers to run stably for a long time. It is recommended to configure an LCD monitor to reduce the harm to the human body caused by long-term computer use.

(2) Types of home Internet access

In ordinary families, the main functions of using computers to access the Internet are to browse news, process simple text, play some simple games, and read Internet video, etc., so users do not need to configure a high-performance computer, and choose a mid- to low-end configuration to meet user needs.

(3) Graphic design type

For such users, because they need to deal with graphics color, brightness, and image processing workload, it is necessary to configure a computer with fast computing speed and high overall configuration. Computers, especially in terms of CPU, memory, and graphics cards, require higher configurations. At the same time, a CRT monitor should be configured to achieve better display effects.

(4) Entertainment game types

Most of the games currently developed use three-dimensional animation effects, so such users have higher requirements for the overall performance of the computer, especially in terms of memory capacity and CPU. There are certain requirements in terms of processing power, graphics card technology, monitor, sound card, etc.

2. Decide whether to buy a desktop or a notebook

With the rapid development of microcomputer technology, the price of notebook computers continues to drop, and many customers who are about to buy a computer are considering whether to buy Desktop or laptop. When buying a desktop or laptop, you should consider the following points.

(1) Application environment

Desktop computers are not very convenient to move around. For ordinary users or users with fixed offices, you can choose desktop computers. The advantage of notebooks is that they are small in size and easy to carry. Users who often travel on business or work on the move should choose notebooks.

(2) Performance requirements

There is a certain gap in performance between notebooks and desktops of the same grade, and the upgradeability of notebooks is poor. For users with higher performance needs, desktops are a better choice.

(3) In terms of price

The price of notebooks with the same configuration is higher than that of desktops. In terms of cost performance, notebooks are not as good as desktops.

Therefore, when it comes to price factors, desktop computers are relatively cheaper.

3. Determine whether to buy a branded machine or an assembled machine

Currently, there are two main categories of desktop computers on the market: one is a branded machine, and the other is an assembled machine (also known as compatible machine).

(1) Brand machine

Brand machine refers to a computer with a registered trademark and independent brand produced by a computer manufacturer with a certain scale and technical strength. Such as IBM, Lenovo, Dell, HP, etc. are all well-known brands at present. Brand machines have undergone strict performance testing before leaving the factory. They are characterized by stable performance, guaranteed quality and ease of use.

(2) Assembling machine

Assembling machine is a computer in which computer accessory sellers combine various computer accessories according to the user's consumption needs and purchasing intentions. The characteristics of the assembly machine are that the computer configuration is more flexible, the upgrade is convenient, and the cost performance is slightly higher than that of the brand machine. It can also be said that under the same performance conditions, the price of the brand machine is higher.

4. Guide to understanding computer performance

For a computer, its performance is not determined by one indicator, but by the overall configuration of each part. To measure the performance of a computer, we mainly look at the following performance indicators.

(1) The computing speed of the CPU

The computing speed of the CPU is an important indicator of computer performance. It is usually described by the main frequency. Popular dual-core CPUs on the market use multi-core technology while increasing the main frequency. The higher the overall main frequency, the faster the computing speed.

(2) Graphics card type

The graphics card processes the image data sent by the CPU into a format that the monitor can receive, and then sends it to the display screen to form a picture. The more popular graphics chips on the market are NVIDIA and ATI graphics cards. The capacity of independent graphics cards is used as a measure of graphics card performance indicators. On the market, independent graphics cards with 2G or higher are the mainstream graphics cards.

(3) Internal memory capacity

Memory is the memory directly accessed by the CPU. All programs that need to be executed and data that need to be processed in the computer must be read into the memory first. Memory size reflects the computer's ability to instantly store information. With the upgrade of operating systems and the increasing functions of application software, the demand for memory capacity is increasing.
