Computer parameters are complicated and difficult to understand, and you often feel at a loss when purchasing? PHP editor Youzi specially compiled this guide to provide an in-depth analysis of the key parameters of each hardware component to help everyone easily understand the configuration table. From CPU clock speed to graphics card memory, from memory capacity to hard drive speed, this article will explain them one by one, so that you will no longer be confused when purchasing a computer. Come find out and make your purchasing decision more informed!
When buying a computer, you mainly look at the CPU, memory, graphics card and hard drive.
1. Select the computer brand and check the CPU parameters. If it is higher than the current mainstream CPU frequency parameters, the CPU performance is better.
2. The number of interface particles and storage size of the memory module will affect the reading and writing speed.
3. Search the motherboard model on Baidu to view specific information.
4. The graphics card is directly related to the response speed of running large program software.
A computer is composed of a lot of hardware, such as CPU, graphics card, memory, hard drive. When it comes to laptops, the size, resolution and screen material of the screen must also be considered.
Motherboards are not considered here, which does not mean that they are not important, but because the manufacturers we usually buy laptops will definitely choose models that match their configurations.
The CPU of a computer is equivalent to the human brain. Currently, the CPUs on the market are mainly divided into two camps, namely Intel (Intel) and AMD. The performance is distinguished by product model.
The most important of the four digits is the first digit, which represents the generation of the CPU. Therefore, the larger the value of this digit, the newer the architecture of the CPU, resulting in higher performance and lower CPU costs. power consumption.
The last three digits usually have little impact on the performance of the CPU, and we don’t need to consider it. The letters that follow at the end are very mysterious. We often see many ultra-thin laptops boasting that they use i7 processors, but in the end the performance is not as good as that of a desktop equipped with i3. The reason is because of this letter.
Step 1: Interface type: Although the PS2 interface is still alive and well, it is just a thing of the past. The keyboard and mouse of this interface are the same as the USB ones. Its biggest flaw is that it does not support hot swapping. Users When replacing the device with the PS2 interface, you need to restart the operating system to take effect.
Step 2: Mouse resolution: This is very important. The unit of mouse resolution is dpi, which means the number of points that can be determined by moving the mouse one inch. The higher the resolution, the more precise the control. This is like correcting a picture. Xuan curve or coxuan curve, the more certain points, the closer the drawn figure will be to reality.
Step 3: Size: Let’s talk about the mouse first. The size may not be obvious if you look at it online. Often, you will find that it feels bad when you buy it. Just imagine what it would be like for a grown man to use a female mouse ( Vice versa), so users must pay attention to the size and weight of the product when purchasing; for keyboards, some products will compress the thickness, width and height for the purpose of reducing size. The consequence is that the elasticity of the keycaps is not good, and the function keys It will be streamlined (such as the direction keys and numeric keys on the right). This keyboard may make it uncomfortable for some users. Everyone must look at the picture carefully when shopping online.
Step 4: Extra functions: Let’s talk about the mouse first. Many current products have multiple function keys, such as forward and backward, which can even be customized. From personal experience, these function keys are basically worthless to ordinary people and do not need to be used. Pay an extra sum of money for this; the same goes for the keyboard. Functions such as opening the browser, mailbox, forward and backward are basically useless, and they are not as fast as a mouse click.
Step 5: Wired or wireless: Wireless is very popular now. For example, everyone online uses wireless routers to share the Internet connection. Nowadays, wireless keyboards and mice can generally be used normally within a range of 10 meters (without barriers). Like me, I bring the wireless keyboard and mouse to my bed to use in winter, which is very cool and happy. As far as sitting in front of the computer and working, there is no difference between wireless and wired.
Step 6: Ergonomic design: Some high-end products claim that their product designs are ergonomic, which means they will be very comfortable to use. I have also used some products and they really feel good, like Logitech’s G1, which is a very classic product. It’s a mouse, but it’s a pity that there are so many high-imitation products, and it seems that this mouse is no longer available on JD.com’s counters.
Step 7: Battery: Wireless products need a transmitter and a battery. There are two types of batteries: built-in and external. External uses ordinary batteries, while built-in lithium batteries are definitely cost-effective if used for a long time.
Step 8: Price: Don’t think that the more expensive one is necessarily better. In fact, the mouse I use in the office for more than ten yuan is very comfortable, but it is better than the keys at home that cost hundreds of yuan a set. Rat's performance is average. When purchasing, users should first ask people around them if they have good product recommendations, and then read the reviews of the product (especially negative reviews).
Amortization methods for companies purchasing computers usually include two types:
First, because the value of computers basically reaches the fixed asset standard. Therefore, the first amortization method is: first include it in the "fixed assets" account, and then extract the (computer) depreciation expenses according to the fixed asset management method. This is the "straight-line amortization method";
The second type is that the purchased tax control computer can be amortized in one go. That is, it will be included in "administrative expenses" and be amortized in one go.
