How to review Zhihu for the final exam of computer networking

Turn to Zhihu. I don't know if your school is a key university or an ordinary university, there must be a difference in the level of the exam between the two, taking myself as an example, the university I went to is not a key university, so the content of the exam is not particularly difficult, but cheating is definitely not allowed, cheating is to be punished and may postpone graduation, so under normal circumstances, the usual class listens carefully and prepares for the review of computer basics two weeks before the exam is completely sufficient.

1. Basic knowledge.

General computer basic knowledge includes the development of computers, number system conversion, computing, storage capacity, hardware foundation, etc., which need to be memorized more, of course, these contents will be understood and recognized when we do practical operations. Therefore, as long as you listen carefully to these contents in your usual classes, you only need to bring them a little before the exam, and you don't need to spend a lot of time to prepare.

2. Software Basics.

The difficulty of this part is that the content is relatively abstract, and there is no specific matter to help us understand, so the focus should be on understanding, such as: data algorithms, linear tables, binary trees, sorting methods, etc., all need to understand + memorize, in addition, the after-class exercises should be brushed more, and many of the question types of the final exam are basically from textbooks.

3. Fundamentals of Computer Networks.

In fact, this part of the content is not commonly used in daily life, unless you plan to engage in related industries in the future, it is recommended that you only need to pay attention to deepening your memory in the exam, and there are really not many places to apply it at other times. It is recommended to follow the key points drawn in the exam to review, and the score ratio of this part has always been not very high, so there is no need to prepare a lot of content.

4. How to memorize + understand?

Because the university may have just started to contact the computer is only more comprehensive, so the knowledge points are more complex, which is very difficult for novices to remember, so we can use the mind map to organize these just content, so that these contents can be displayed more systematically, which is more conducive to understanding and memory, as shown in the figure below.

This kind of diagram can be combined with words and pictures, making full use of the skills of the left and right brains, and using the rules of memorization and reading thinking to help people balance logic and imagination, so as to inspire the human brain. This method of review can greatly improve the thinking ability, which is generally not valued in the student life of Chinese students, so you can use similar mind maps to improve your thinking ability.

5. Dry goods sharing.

Finally, a few words, some students think that as long as the university does not fail, it is good to graduate successfully, but you are a college student, how many people envy the object, should not stay in the state of getting by, should pursue a better self is is, many people are after graduation began to regret that they did not fight for any opportunity to change themselves when they encountered the next opportunity, but they did not have the conditions to fight. Therefore, students must cherish their time in college! In particular, learning the knowledge of professional courses well will become a necessary stepping stone to find a job!

**Exam: The administrator can import test questions in batches, randomly select questions to group papers, and draw questions according to the difficulty of different knowledge points.

1 second is 56kb, then 2 seconds is 112kb, 20 seconds is 1120kb, 60 seconds (1 minute) is 3360kb is about equal to about 3m, a total of 5m to transmit, to this can directly calculate the equal b, the rest are too different.

Summary. It adopts a hierarchical structure and is divided into two layers, and all routes are 8-port routes. Layer 1 routing address, other subnet masks, etc., the WAN interface of Layer 1 routing is connected to the external network; There are 5 routes in the second layer, and the addresses are in order

The address of the second-layer route enters the route (the default is to modify the management address of the route, and it is OK to modify it in turn.) The third layer is the computer, all addresses are automatically obtained, and the network segment itself is modified to the DHCP allocation pool of the route.

Do you have any knowledge of computer networking? Can you help me with this question? Thank you.

Do you have any knowledge of computer networking? Can you help me with this question? Thank you for the pro who entered.

A company has 1 building, a total of 10 floors, about 20 offices on each floor, each office is designed with 4 network information points, the optical cable outlet is designed in a simple room on the first floor of Building A, please design its integrated wiring project, and complete the following documents in accordance with the standard template: the first question Demand analysis The second question The overall design of the integrated wiring The third question The design of each subsystem The fourth question The selection of wiring products The fifth question Network topology design.

Woo woo, I'm going to do my homework tomorrow Please<>

Look at it, dear.

OK. Hmmm.

How do you write a requirements analysis?

It adopts a hierarchical structure and is divided into two layers, and all routes are 8-port routes. The first layer carries the routing address of the bad layer, other subnet masks, etc., and the WAN interface of the first layer routing is connected to the external network; There are 5 routes in the second layer, and the addresses are in order, the address of the second-layer route enters the route to argue for rough leakage (the default is to modify the address of the management bench of the route, and it is OK to modify it in turn.)

The third layer is the computer, all addresses are automatically obtained, and the network segment itself is modified to the DHCP allocation pool of the route.

What about the overall design of the integrated wiring<>

The first step: conduct a field investigation on the location of the wiring project, collect data, and make a plan for the deployment of equipment; Step 2: Write down the construction requirements of the project and explain the standards adopted by the project; Step 3:

Draw the construction plan (with Auto CAD); Step 4: Establish a construction organization, do a good job of division of labor, (Gantt chart can be used to track the progress of the project, Microsoft project is recommended) and clarify the specific responsibilities of each division of labor team; Step 5: Write down how to do a good job in the quality of the project; Step 6:

According to the construction plan, budget the cost of the project bridge and make a list of materials; Step 7: Establish the rules and regulations of the construction team; Step 8: Layout and beautify the whole plan.

c wears a red hat.

There are 3 red, 2 white, for 3 people.

If A can see the colors of B and C, and does not know what color his hat is, it means that B and C are not all white, otherwise A can know that he is red.

After A finishes speaking, B can see the colors of A's and C's hats, and can tell from A's words that he and C are not white. Therefore, C is not white, otherwise he would know that he is red.

After listening to A and B, according to our above logic, we can find that C is not white, then it can only be red.

4. Flow control.

Multiple choice questions 2, A 3, B 4, D 5, C 7, D

These are the ones I will, because I haven't seen them for a long time and forgot them.

Brother, your roll is **, why is it exactly the same as mine, do you have an answer, can you share it with me, thank you.

Subnet number Host IP Subnet mask Subnet broadcast IP

It can be divided into 8 subnets required above, and any 6 of them can meet the requirements of the topic!
