Answer: a) it is used as a password.
Explanation:
In order to be able to exchange routing information , CISCO routers use an authentication process, so when they send a message (a HELLO message for instance) the router that receives the message confirms that the message is authentic.
There are several types of authentication in OSPF, null, plain and MD5.
The difference between them is as follows:
1) null, implies that no password is included in the packet header, it's the default mode.
2) plain: In this type of authentication, the password is sent transparently from a router to his neighbor, as a plain text which makes it vulnerable to attacks from packet inspection software, like Sniffer.
3) MD5, is a more secure mode, in which the password is not sent directly, but a hash built based on the packet contents and the password itself instead.
MD5 (Message Digest 5) is the name of the algoritm used to build the hash that receiver will compare with the sent by the sender in order to confirm authentication.
The chosen password, is placed at the end of the command, after the type of authentication (MD5 in this case), which in this case is "CISCO-123".
Answer:
1. Supercomputers
Supercomputers are very expensive and very fast. They are the most powerful computers we have in the world.
Supercomputers are optimized to execute only a small number of programs. This makes it possible for them to execute these few programs at a very high speed. Due to their inhibiting cost, they are used in high-end places like in scientific research centers. The supercomputer consists of thousands of processors, allowing it to clock in at very high speeds measured by petaflops.
These computer types are also very large in size due to the numerous parts and components involved in their design.
A good example of a supercomputer is Tianhe-2, which is located in the National Supercomputer Center in Guangzhou, China. It features 3.12 million cores, allowing it to run at speeds of 33.86 petaflops.
2. Mainframe Computers
These are large and expensive computers that are capable of supporting thousands of users simultaneously. They are mostly used by governments and large organizations for bulk data processing, critical applications, and transaction processing. They are ranked below supercomputers.
3. Minicomputers
Minicomputers are mid-sized computers. In terms of size and power, they are ranked below mainframes. A minicomputer is a multiprocessing system capable of supporting from 4 to about 200 users simultaneously.
The use of the term minicomputer has diminished since the introduction of microprocessors. These machines are now more commonly called midrange computers.
4. Microcomputers
A microcomputer, also known as a personal computer, is designed to be used by one user at a time. The term microcomputer relates to the microprocessor that is used for the purpose of processing data and instruction codes. These are the most common computer types since they are not very expensive
The answer to this question would be algorithm animation.
Since the algorithm is animate, then you will be able to watch it works. Watching the algorithm executed can give you much information, what the algorithm does and how the algorithm does it.
Normally you will not be able to do this since the algorithm only do what it needs to do without reporting the detail to you
Imagine cashing or taking money using the Automated Teller Machine (ATM) and the banking hall, the two ways are When it involves convenience, not anything can beat ATMs.
<h3>What are the benefits and drawbacks of the usage of an ATM card?</h3>
No credit score allowed: A debit card is related for your financial institution account. There isn't anyt any opportunity of creating any transaction on credit score. All transactions and withdrawals are restricted to the stability to be had for your account. Difficult to dispute fraudulent use: It is less difficult to fraudulently use your debit card.
Automated Teller Machine (ATM) – It is a digital system that is operated with the aid of using clients and lets in acting for monetary transactions consisting of switch funds, coins withdrawals, and deposits. It extensively utilized for acquiring account facts at any time and with out the assist of financial institution staff.
