disadvantage is that the cost of storage is high. RAID5: Its read and write performance has been improved, fault-tolerant, at least 3 pieces of disk, is a combination of relative raid0 and RAID1, while performing parity, its disk space utilization is higher than RAID1, but the cost is relatively low. RAID10: Its read and write performance has been improved, fault-tolerant, each group of images can only be bad piece, storage data volume, security high, at least 4 disk, it is the array to do RAID

person's physiology characteristic, experience, education, religious belief;The people who are respected need to have a stable social status and demand that their abilities and achievements be recognized by society. The need for respect can be divided into internal respect and external respect. Internal respect refers to a person wishing to have strength, competence, confidence and independence in a variety of situations. In short, internal respect is human self-esteem. External respect refers

I personally feel that there is absolutely no need. If you are a student, lie in an ivory tower. You can easily toss your page, because you are the customer, you just have the time, you are the pursuit of perfection. But commercial p

Given a non-empty binary tree, return the average value of the nodes on each level in the form of an array.Example 1:Input:3/9 20/15 7Output: [3, 14.5, 11]Explanation:The average value of nodes on level 0 are 3, on level 1 are 14.5, and on level 2 is 11. Hence return [3, 14.5, 11].Note: The range of node ' s value is in the range of 32-bit signed integer. # Definition for a binary tree node.class TreeNode: def __init__(self, x): self.val = x self.left = None

I like Jin Yong's martial arts, and I am happy with his novels. For example, his sword, from the unsung sword, the Xuan iron sword, to the wooden sword and even the final no sword, does not know how many xuanjicang will be broken in the world. The software design is similar to the sword. Let's take the familiar permission design as an example. Let's talk about three levels of permission design. Level 1: a sword in the hand and a sword in th

It is said that there are three levels of marriage.First priority: Marry a person you love.Second: Marry a person you love and his/her habits.Third, marry a person you love, his/her habits, and his/her background. Couples in the first realm have relatively stable marriages.Couples in the second realm have a solid marriage.Couples in the third realm seldom see divorce. In this world, the old people are basically married three times in their life.Fo

Redundancy, but only one copy of each data block and its data can be corrupted, and if damaged at the same time, the overall data will be corrupted. For example, when Disk 1 is damaged, the remaining three disks, only if Disk 2 is damaged, the ent

The topic of old growth talk, in the interview of the ability of the inevitable assessment, I personally think the problem-solving ability is ranked first, higher than the ability to learn the priority. The ability to solve problems can be seen ProgrammerOf ThinkingAbility, adaptability, exploration ability and so on, can see his experience. If the problem solving ability is not able to pass the interview. For example, if I execute a PHP script, such as PHP test.php, it is expected to return a

programmers? A joke, if I told you that programmers can be divided into eight levels, what would you think?1.The Immortal programmer: This is the highest level. The code you wrote did not go with you, but it was preserved (last forever). You will be immortal in the computer field. Other programmers will study your accomplishments and writings. You may have won the Turing Award, published a powerful paper, or invented one or more basic technologies kn

Know chuangyu I personally think security can be divided into several popular levels. One level is: you do not know, this is the most basic level, such as the password authentication mechanism, but it is also a relatively fragile level that you do not know, the vulnerability of the system can be grayed out, for example, through direct disassembly and verification, or through some means, such as internal information leakage. One level is that you do

1, TTL level:The output level is greater than 2.4 V, and the output level is less than 0.4 V. At room temperature, the output high level is generally 3.5 V, and the output low level is 0.2 V. Minimum input height and low level: Input height> = 2.0 V, input low level 2, CMOS level:1 logic level voltage is close to the power supply voltage, 0 logic level is close to 0 V. It also has a wide noise margin.3. Level conversion circuit:Because TTL and coms have different high and low

IOS supports three levels of thread programming, from the underlying layer to the high-level (the higher the level, the more convenient to use, the more concise) are: 1: thread; 2: cocoa operations; 3: Grand Central Dispatch; Introduction: ThreadIt has the lowest abstraction level. The other two thread applications encapsulate thread. For programmers, thread is relatively troublesome and requires programmers to manage thread cycles, but the efficiency

refactoring. The following is a list of modified content: 1. Check whether the value of nextProjectile is nil at the beginning of the function. This means that our current touch event is happening in the shooting process. That is to say, the turret has shot a bullet. 2. Previously, we used a projectile local variable and added it to the current scenario. In this version, we added a member variable of nextProjectile, but it was not immediately added to the current scenario. Because it will be us

. serializable)Meaning: In a multi-user environment, user a starts a transaction and queries all records in the test table. Then, user B inserts (or deletes) the transaction) in the test table, a record is submitted and the transaction is committed. At this time, user a executes the previous operation to query the entire table record, and the result will be an extra (missing) record. This operation is called an illusion. (DEMO) Solution:Before user a runs a transaction, set the SQL isolation l

Not all analysis methods work the same way. Like most software solutions, you will find that the capabilities of analysis methods are also different, from simple to advanced complexity. Next, we divide the analysis capability into eight levels based on the intelligence that different analysis methods can bring to people. 1. Standard reports A: What happened? When did it happen? Example: monthly or quarterly financial report We have seen reports, which
