Hi, I’m Latiao.
I want to go to college, learn the computer related professional want to buy a computer, ask me what can recommend, this is to ask the right person, I still have a certain understanding of the computer, I believe there are a lot of friends will certainly have this problem, today specially out an article to talk about learning programming how to choose a computer.
Computer science needs analysis
1. C language
There are many C editors:
- Code::Block
- Dev C++
- VisualStudio
The most demanding of these is VisualStudio, dubbed the “first editor in the universe”.
A 64-bit CPU with a frequency higher than 1.8GHz is required, and four or more cores are recommended.
2, memory,
Requires at least 4 gb of memory.
3, hard disk
At least 0.85 GB disk space is required. A maximum of 210 GB disk space is required depending on the function module to be installed. It usually takes 20 grams.
In fact, now the general installation of general demand in 6G ~ 15G.
4, hardware,
The screen resolution we’re talking about here is 1280 x 720, 1366 x 768 or higher recommended.
The above is the Visual Studio system hardware requirements, summary:
4 Core CPU + 4G RAM + 20GB SSD + 1366 x 768 resolution screen
Don’t remember. Just get an impression.
2. Java language
Let’s take a look at IntelliJ IDEA, a common Java editor.
- Memory: 8G or above is recommended
- CPU: Multi-core CPU is recommended
- Hard drives: A solid state drive of at least 5 gb is recommended
- Resolution: 1920×1080 recommended
- Operating system: 64-bit is recommended
When you run Linux virtual machines on your computer, the memory footprint is high. The memory footprint is also high when you have multiple projects open at the same time with the editor. By the way, the memory footprint of current Chrome software is also staggering. Therefore, a computer with 16G memory is recommended for computer majors
Laptop analysis
Here’s what we need to know when we’re shopping for a laptop:
1, budget,
- Budget:
According to the performance and price of notebook computers, they can be divided into high-end computers (above 9K), mid-end computers (5K 9K), and entry-level computers (3k 5K). Those who have sufficient budget and are too lazy to choose high-end computers directly choose them without thinking. The higher the configuration, the better.
Mid-range machines, with their superior performance and lower price than high-end machines, are the best choice, but you need to do a lot of research before buying. The entry-level function meets daily office and entertainment needs, suitable for workers and students on a tight budget.
2, CPU,
Processor /CPU:
The processor (CPU) of a notebook is equivalent to the brain of a notebook. As the core of computing and control of the entire computer system, it determines the smoothness and responsiveness of a computer and is one of the most important parameters. At present, the two main brands of CPU are Intel and AMD.
Intel (Intel) CPU series: Core series (high-end), Pentium series (entry-level), Celeron series (low-end entry-level). Among them, the notebook is the most common core series. Under the Core series, there are i3, I5, I7, i9 and so on, representing different product lines, each product line is divided into different versions, each generation of CPU and
AMD’s market share is second only to Intel in China, and its CPU products have the advantages of high cost performance and high performance. It is impossible to say which Intel and AMD’s processors are better, with different models. The comprehensive performance must be measured by combining the computer’s graphics card, memory, heat dissipation design and many other factors. AMD’s CPU series is divided into Sharp dragon, AMD FX, APU, Rapid dragon, flash dragon and so on. The most common laptop is the Ryzen series, which has R5, R7, R9 and other product lines, as well as different suffixes for different models.
3. Video:
If the CPU is the brain of this, the graphics card is the visual system of this, and then the smart brain also needs someone to help it express, so the CPU and graphics card are the most core components of the computer.
Now graphics card graphics chip suppliers are mainly AMD(formerly ATI) and NVIDIA two. Laptops differ from DIY assembles in that the CPU and graphics card are usually already in place, the CPU is soldered to the motherboard, mass-produced, and most do not support replacement. Video card noun:
Video memory: Used to store rendering data processed or about to be extracted by the graphics chip. Independent graphics card: display chips and related components, radiator and other production into an independent board card from the computer motherboard, usually need to plug in the corresponding interface on the motherboard, it has independent video memory, does not occupy the system memory, the best performance and display effect, convenient replacement. Integrated display card: different from independent display card, it will display chip, sound card, network card are integrated on the motherboard, basically can not be disassembled, although its game performance and display effect is not as strong as showing alone, but the price is close to the people. Core display: full name core graphics card, is also a kind of integrated graphics card, display chip integrated in the CPU, this machine has the taste of “buy CPU to send graphics card”, relying on the processor’s powerful computing capacity and intelligent energy efficiency adjustment design, performance and fluency is very strong, low power consumption. Single or dual display: Single display means only one display card, while dual display means two display cards, which theoretically have higher performance but also higher power consumption.
3. The hard drive:
Divided into solid state disk and mechanical hard disk, now the new notebook sub-hard disk is generally a solid state disk. It is a computer storage medium, that is, we often say fixed memory, such as the example of lenovo small new Pro16 fixed hard disk capacity is 512G.
Laptop hard drives can be replaced if you think they have limited capacity or are malfunctioning. In addition, some laptops in addition to their own hard disk, reserve a hard disk slot, convenient for users to expand.
4. Memory
The memory of the notebook is also called THE RAM. The system and software on the computer need to run on the RAM, which is used to temporarily store the computing data in the CPU and the data exchanged with the external memory such as the hard disk.
The bigger the memory, the more software the laptop can run at the same time, the smoother it is, and many books support extra memory chips (look out before you buy). For example, lenovo small new Pro16 memory is 16G, in the current mainstream level of the market.
5. Upgrade
After the performance and parameters of a notebook are clearly understood, purchasing channels can be divided into online and offline. Notebook this product is different from mobile phone, process is complex, general brand notebook will not have fake, only two mobile phone and the difference between the new machine. When buying, consider after-sales service first, discount second.
Offline is to go to the local computer city or brand store, the advantage is to see the object, but also on the spot experience. Like Gome, Suning this kind of big shopping mall is good, if it is a computer city, white did not do homework in advance, it is easy to be fooled by the salesman (after all, others have commissions), the price is not unified, do not suggest to the line to buy machine.
Online preferred jingdong self-run, Tmall flagship store, Suning flagship store, etc., after all, there are 7 days without reason to return, warranty service and after-sales protection, I personally prefer jingdong self-run, because it is really delicious. Another advantage of online shopping is that there are big discounts on 618, Singles’ Day, the back-to-school season and major holidays.
Notebook recommendation
These professional CPU performance and graphics card requirements are very low, the current mainstream laptop, just take a computer out.

Make big data recommendations
Big data is mainly about data analysis and processing. Use Python tools such as Hadoop and Spark to crawl, filter, and analyze data on the network. Clean, process and analyze massive data, find the rules, and then apply them to achieve accurate marketing, etc.
Big data is still high and low; But there are differences, can involve the virtual machine more open, it has higher requirements on the computer’s memory and heat dissipation performance, so when we choose and buy, generally based on 16G, it is best to expand the memory of the notebook.
