2. What does nature teach us? People can learn a lot of philosophy in nature.

(2) Nature also gives us the inspiration that time is hurrying and we must cherish it.
3, the revelation of nature composition how to write (1)Childhood is a happier time in our lives, but also a more innocent and lively time. In childhood, we make all kinds of discoveries. That morning, I watered the flowers on the balcony, accidentally found a spider, the spider has eight feet, it is weaving a web. I put down the bucket in my hand and carefully observed the spider's web. Although ants are small insects, but this inconspicuous little guy has given me a revelation: unity is strength, persistence is victory.

5, pen gift box pen as a gift to the teacher, is absolutely not wrong. This pen color is fresh and artistic, each color represents a different city, is very suitable for female teachers and female class teacher gifts. German fruit tea gift box selected high quality raw materials, the use of physical drying sterilization, the packaging is very nice and fresh and beautiful, the teacher lectures every day, but also need to protect the voiceDrink more water, moisten the throat, flower tea let the teacher fall in love with water.
6, the female head teacher needs to drink tea to relax in the work every day, therefore, you can send a delicate handmade tea set as a gift.

I believe that the female homeroom teacher also likes to read, so a good book is a good choice for gifts.
Circuit switching: A complete path must be set up before data transmission. Before the line is dismantled (released), the path is fully occupied by a pair of users. Circuit switching efficiency is not high. (2) Packet exchange: Packets are transmitted from the source point to the destination in the store-and-forward mode, and packets need to be queued. Therefore, message switching is not suitable for interactive communication and cannot meet the requirements of real-time communication.
Data exchange mode and advantages and disadvantages: storage and forward mode: (1) Advantages: to ensure the error-free transmission of data frames. (2) LackDot: The transmission delay is increased, and the transmission delay increases with the length of the data frame. Fast forwarding mode: (1) Advantages: low latency of data transmission. (2) Disadvantages: It is impossible to verify and correct the data frame. Free segmentation mode: The performance of this mode is between store-and-forward mode and fast forward mode.
Line switching: This type of switching, suitable for public telephone networks, establishes a dedicated communication path along which data is transmitted directly. Store-and-forward switching: This method is suitable for datagrams and virtual circuits. The datagram is routed independently in the network, while the virtual circuit is pre-establishedIndicates a logical path. Message switching: This mode of switching is suitable for electronic mail systems (E-mail).
has the advantages of circuit switching and message switching. After each packet is identified, a dynamic multiplexing technique is used on a physical line to transmit multiple data packets simultaneously. Packet switching has higher circuit utilization, lower transmission delay and better interactivity than packet switching.
③ Reduces the probability of error and the amount of retransmission data. Because the packet is shorter, its error probability is necessarily reduced, and the amount of data transmitted each time is greatly reduced, which not only improves reliability, but also reduces transmissionA delay. Because the packet is short, it is more suitable for using the priority strategy, which is convenient for timely transmission of some urgent data, so for burst data communication between computers, packet switching is obviously more suitable.
2, a person died, with the windAnd whether it is to go, whether it is to turn into a butterfly and dance, what will be left for posterity is a heart-wrenching sadness, even if he went to heaven, went to a more beautiful place without loneliness and sadness.
