How do you tell the difference between good and bad hosting? What is the difference between a consol

The host mainly depends on the motherboard, and it is necessary to pay attention to the CPU, frequency, graphics card, memory, cache, and stability of the machine in the configuration.

How to evaluate the quality of web hosting! Choose a good web host, the following points you need to pay attention to: 1, the strength of the web hosting service provider, now there are too many web hosting businesses, mixed, sunny, before buying web hosting, first review their qualifications, whether it is authoritative certification, whether there is a formal ICP business license.

While this alone cannot be judged, this can be used as a reference for the first level. 2. In terms of the speed of the virtual host, it is necessary to test it more. It is best to try your own ** in different locations, different time periods, and different connection methods, to see how fast the web host is, and don't forget that practice is one of the means to test the truth.

3. In terms of functions, when users choose virtual hosting, they must pay attention to the functions they must use at present, such as corporate mail, ** service, etc. Other features are added when needed, don't go for big and complete. 4. In terms of product lines, it is very important to pay attention to the product lines provided by web hosting.

Large-scale web hosting providers will provide a very detailed application solution to users in different industries and different fields, such as some virtual hosts will increase the gift of corporate mail, some will be pre-installed, blog programs, etc., we can choose web hosting according to our own situation. 5. In terms of service, this is the most important point of all the options. There is no web hosting product without a little problem, the key is whether the service can keep up if there is a problem, generally those capable and strong web hosting companies will have such services.

So that's also a reference.

The difference between a console and a PC is that the concept is different and the relationship is different.

1. The concept is different.

Personal computers, abbreviated as PCs, are collectively referred to computers that are suitable for personal use in terms of size, performance, and price, and are directly controlled by the end user. It is composed of a hardware system and a software system, and is a device that can operate independently and complete a specific function. Desktops, laptops, tablets, and ultrabooks all fall under the category of personal computers.

The main unit refers to the main part of the computer other than the input and output equipment. It is also a control cabinet used to place the motherboard and other major components. This typically includes CPU, memory, hard disk, optical drive, power supply, and other input/output controllers and interfaces.

In network technology, it is about the terminal equipment that sends and receives information.

2. The relationship is different.

The host usually refers to the chassis part of the PC, so the PC includes the computer host, and the computer host does not include the PC.

Composition of a PC computer

1. Computer hardware, located at the lowest level, computers without software are used to be called "bare metal", and bare metal cannot work.

2. The software that is closest to the hardware of the operating system, it controls the hardware downwards and supports other software upwards. Other software must be supported by the operating system in order to run.

3. Utilities, including various practical software, such as language processing programs, database management systems and various utility programs. It is often possible to think of a computer system as a set of applications without caring about the hardware details of the computer.

The relationship between software and hardware is not absolute, and any search and merge operation in the computer can be realized by both software and hardware, and the same is true for the execution of any instruction. The software and hardware of a computer system can be transformed and complemented by each other. As technology continues to evolve, the lines between software and hardware will become increasingly blurred.

If you build your own computer, that's theoretically true; But at the same time, it is necessary to take into account the compatibility performance of different accessories; The biggest impact is the motherboard, CPU, and memory, the motherboard is fortunately able to support the basic status quo, and the core frequency of the CPU matches the memory access speed as much as possible.

There is no best, there is no worst, only the fit!

If you want to look at the brand, Founder, don't buy that kind of brand.

This computer is good, at least better than mine.

Look at the hardware compatibility and the cost performance of the configuration.

If you only look at one item, this is so.

But a host looks at the overall performance, and the outstanding performance.

The combination of each component maximizes the utilization of each component.

If the CPU is too good, the utilization is only half and the other half is wasted.

Prepare a USB flash drive with built-in CPUZ

Master Lu (Green Version).

Hardware test software.

Check the accessories for your new computer.

Package insert.

Whether the accessory is unsealed in person.

Date of manufacture. The closer the better.

The motherboard should be carefully looked at both sides.

Whether there is wear and tear.

Especially on the back, there is part of the motherboard due to.

When installed in a small chassis.

Due to the mistake of the installer, the wiring on the back of the motherboard will be broken, and the motherboard after repairing it is prone to problems.

The boot can be viewed with the test software.

Hardware manufacturers. Make and model.

Operating temperature. Check whether each voltage is normal, and check whether there are dead pixels on the display.

It changes every day.

Generally, the quality is stable, and the quality is also stable.

Such as Hitachi HDD, constructive comments.

It is to avoid all kinds of problem hardware, and do not use WD for hard disks

Drop the speed gate, 6 series motherboards before April 2011 motherboards have interface problems to detect B2 has a problem, B3 is a recall after the correction is no problem. Dell's monitors have a high rate of repair, and the probability of buying a repair item is high. Before buying, you can do some homework, pay attention to the major hardware** reports on problem hardware and counterfeit parts, and prevent being recruited.

The performance of a computer depends on five main things:

1、cpu。The larger the number of cores, the faster the operation. At present, the common household is quad-core, and there are also eight-core.

2. Memory: The larger the memory, the faster the computer will respond. At present, 2G, 4G, and 8G are commonly used at home.

3. Graphics card: The larger the video memory, the faster the response, especially for professional graphics and playing large-scale online games. At present, the household memory is generally 1G and 2G.

4. Hard disk. The capacity and speed of the hard drive determine the performance of the computer. At present, the 1T hard disk commonly used in households. In addition, solid hard drives have emerged.

5. a motherboard. The performance of the motherboard and the number of slots determine the performance of the computer and the room for future upgrades.

Suitable for the best, don't pursue any high matching, for a little bit of performance improvement that you can't feel at all, it's really a fool's thing to do.

See the model of each hardware in which the computer is configured. parameters and **.

The same price, but whoever has the best running speed and running score is good, and it is cost-effective!

Brand Performance Parameters Refer to ** Host Configuration Service Life.

Boot to check the computer model,If there is AIDA64, it's best,If not, it's like other test tools such as 360 hardware,Master Lu can also make do with。 Verify whether the computer hardware matches the seller's description.

After the above aspects are checked, shut down and cut off the power supply, open the side panel of the chassis, first look carefully to see if some of the logos and barcode paper on the motherboard have been modified or damaged, and then see if the components on the motherboard have not been replaced, the most popular is whether there are individual relatively new or obviously different from other component brands of the same specifications. Then look at whether the hard disk has any trauma, whether the labeling is damaged, or the labeling is very new, and there is a phenomenon of secondary labeling. Then disassemble the radiator to see if the CPU has scratches and bulges, and whether the pins are intact or broken.

Whether the memory is repaired or not, the inspection method of the graphics card and the motherboard is similar. whether the power supply is too old, etc.

Check whether the monitor has been disassembled and whether the menu buttons of the monitor are sensitive. Whether the color and image quality are normal. Fourth:

Check the periphery, that is, whether the expansion sockets of the host can be used normally, and whether some other peripherals can be used normally. Although the above is relatively simple, these are some of the main identification methods for buying a used computer.

Again, there is a risk in second-hand, and you need to be cautious when buying.

Just look at a few big things: CPU, hard disk, memory, graphics card and other hardware configuration.

The simplest thing is the boot speed, and the fast one is OK.

Then I right-click on my computer to see its properties, look at the CPU memory, CPU you don't understand, the larger the memory, the better, and look at the capacity of the hard disk, look at the graphics card video memory.
