Probably not.

Dual-core refers to the CPU with dual core technologies

The effect is noticeable when executing multiple files.

*4 on the memory means that there are 4 memory slots, but in fact, there is only one 512MB memory.

Hard disk 400G refers to the maximum support of 400G hard disk.

RAID0 is the meaning of the disk array, ICH7 is the South Bridge, this South Bridge supports RAID0***16X, is the *** optical drive, and Combo is the recorder.

Only the disc can be put Combo can watch *** cd vcd, etc., and you can also burn the CD disk.

400GB*2 is Explanatory Provision 2;

16X ***RW can do 16X speed *** burning, while Cobmo can only read***, burn CDs, not burn***.

L2 800MHz dual-core: refers to a CPU with two cores that can support the operation of multi-directional tasks.

512MB DDR2-667*4 4GB: Yes, your current RAM is 512, and your motherboard can be upgraded to up to 4G

400GB*2 (7200 rpm 8M cache RAID 0): refers to dual hard disks, each with 200G each

16x ***-ROM: is *** optical drive, combo (Combo) is a CD *** plus CD burner

In daily life, laptops are more convenient than portable search computers. With the development of the Internet age, people have also created lighter, thinner and lighter laptops. And the function of mobile phones is becoming more and more powerful, to a large extent, replacing the use of computers in life.

How to choose a computer.

1. Look at the brand - different brands have different advantages and disadvantages in some characteristics, so the brand is very important; Moreover, well-known brands are much better than low-profile brands in terms of after-sales, maintenance, and cost performance.

2. Look at the battery and power adapter - buy lithium batteries as much as possible, and for power adapters, you should pay attention to the fact that after working for a long time, if the temperature is too high, it is abnormal.

3. Look at the heat dissipation system - whether the design of the heat dissipation outlet is reasonable, don't open the book will block the air outlet, which will affect the heat dissipation. Try not to have a network cable interface next to the air outlet of the radiator, as the temperature rises, it may affect the quality of the network. Know.

4. Look at the size and weight - different notebooks have different sizes, including 12 inches, 13 inches, etc., and the types include thin and light books, gaming books, etc. In general, the higher the configuration, the higher the notebook, the higher the **, and the weight will increase accordingly.

5. Look**——**: As the saying goes, you get what you pay for. When buying a computer, don't be greedy for cheap, and go to buy a low-cost, relatively cheap laptop.

Frequency, X-level cache.

Memory, hard disk, video memory, etc.

I write only the main one, without copying:

Display: Dimensions.

CPU: frequency and cache size.

Memory: The maximum capacity and frequency supported.

Hard disk: capacity, speed, cache.

Graphics card: Computing chip model, video memory capacity.

Sound card: model number is sufficient.

Mouse and keyboard: model is sufficient.

Speaker: Channel, Model.

CPU: External Frequency, Frequency Doubling, Main Frequency, Level 1 Cache, Level 2 Cache, Front-End Bus, Manufacturing Process, Core Interface.

Memory: Frequency, process, latency are a lot.

Motherboard: Interface chipset.

Hard disk: number of revolutions, single disk capacity, cache.

The main parameters of computer performance are the performance of the CPU (core architecture, main frequency, cache, instruction set, etc.), the capacity of the memory, the speed, the capacity of the hard disk, the performance of the graphics card (display core, memory bit width, frequency capacity, etc.), the specifications of the chipset, etc.

When buying a computer, you need to look at the four major parts of the computer: the processor (CPU), memory, graphics card, and hard disk.

Here's a quick run:

1. Dual-core processor + 2G memory + integrated graphics card + mechanical hard disk. The performance meets the needs of small games such as surfing the Internet, watching movies, chatting, working, and playing chess. **Available within 2000;

2. Quad-core processor + 4G memory + independent graphics card + mechanical hard disk. In terms of performance, it can meet the needs of surfing the Internet, watching movies, chatting, working, drawing, playing stand-alone games or online games, ** can be bought within 2000 4000;

3. Quad-core processor + 4 8G memory + mid-to-high-end independent graphics card + mechanical hard disk or solid state drive. In terms of performance, it can meet the needs of surfing the Internet, watching movies, chatting, working, making pictures, playing large-scale stand-alone games or large-scale online games, **You can buy it within 4000 5000;

4. Six-core processor + 8G or more nickname + high-end independent graphics card + mechanical hard disk or solid state drive. In terms of performance, it can meet the needs of surfing the Internet, watching movies, chatting, working, making pictures, playing large-scale audiophile-level stand-alone games or large-scale online games, ** can be bought above 6000.

Therefore, what performance computer you need, you can choose according to your needs.

The CPU generally depends on its main frequency.

Graphics card - mainly the size of the video memory plus the number of bits.

Hard disk - mainly the number of revolutions, size, and interface type.

Memory - mainly frequency, size, algebra.

...What is the high occupancy rate of the system disk? The system disk is a system, and other software that is installed should not be installed in the system disk'l

You don't play online games and large-scale stand-alone computers, and the current computer will actually run out of memory, I don't understand this, what configuration is the computer you use now.

In other words, according to your requirements, according to the current standard configuration, it is completely enough for you to use, and now it is basically 4G memory, core i3-i5 processor, as for the graphics card, you yourself have said that there are no requirements.

First of all, I recommend you to buy Lenovo Y series - This is my impression after finishing college The configuration is absolutely good After-sales service is also good All over the country And then tell you what to see First of all, the CPU now seems to be the best i7 It is said that there are already better than this But after all, it is not popular Anyway, i7 is generally very expensive Generally, we use i5 is enough Memory at least 2g graphics card at least 1g As for the size of the hard disk, it doesn't matter Now it's generally 1T or 500G It's enough to use the graphics card to buy a discrete graphics card This is very important.

The next Master Lu can be tested.

The motherboard frequency is the speed of computer processing, for example, the high frequency is generally fast;

If the graphics card is good, the screen is clearer, and the game screen is smoother;

Get a better computer,CPU AMD255 or 4 cores on the line,,Very good,The built-in CPU fan can be thrown away,The fan is super poor,100Buy one more,The motherboard is colorful,With a 512MB colorful independent display,As for the 1G independent display,It's not much better than 512,Mine is 2G NVIDIA,I think it's the same,The power supply and chassis are arbitrary,The power supply is better,Western Digital hard disk,Don't buy 320G,Buy 500G,You'll find **almost。

If you're playing big games, right now the computer can: Processor: 4 cores.

RAM: 2G graphics card: It is recommended to change to a discrete graphics card.

Discrete graphics cards are easier to use. These configurations are suitable for the average game.
