Suppose that a computer can read or write a memory word in 5 nsec. Also suppose that when an interrupt occurs, all 32 CPU regist

ers, plus the program counter and PSW are pushed onto the stack. What is the maximum number of interrupts per second this machine can process?

Answer:

<em>2,941,176 interrupts per second</em>

Explanation:

Given that:

<em>The number of words = </em>1 PSW (program status word) + 1 program counter + 32

                                        CPU registers  

                                     = 34

<em>The time taken to R/W  a memory word = 5 nano seconds </em>

Prior to the interrupt, 34 words are needed to be pushed into the stack, and 34 words are needed to pop out of the stack after the interrupt is handled.

Therefore, in total 68 words are needed during the Read and Write execution.

To calculate the number of interrupts handled by the machine, we have to first establish the time required to read and write 68 words:

= 68 x 5nsec

= 340nsec

= 340 x 10^{-9} sec (converting it to seconds)

maximum number of interrupts = \frac{1,000, 000,000}{340} = 2,491,176 interrupts.

Answer:

SSH, HTTPS and SMTP

Explanation:

Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

Hence, SSH, HTTPS and SMTP are considered as secure network protocols.

HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).

SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.

Advatages and disadvantages of power-concentrated train​
allochka39001 [22]

Answer:

1. Safety:

2. Cheap:

3. Increases Employment:

4. Bulk Quantity:

The Disadvantages of Rail Transport are as Follows:

1. Loss of Goods:

2. Unsafe for Fragile Items:

3. Late Bookings:

4. Unsuitable for Short Distances:

5. Unsuitable for Rural Areas:

Explanation:1. Safety:

Transportation by the means of railway ensures safety for the desired goods because unlike the road transports a train only stops at a desired station instead of the will of the driver. In case of road transports for example, the drivers can at any point of time decide to rest or stop for tea, refreshments, lunch or dinner.

2. Cheap:

Railway transport any day is cheaper as compared to air transport. As a matter of fact, railway transport is even cheaper than road transport because of the reason that goods in bulk quantities are carried from a desired destination to the other. In cases of road transport for instance, less goods as compared to road transport can be carried.

3. Increases Employment:

Railway transport helps people to carry cheap products from a place to another and sell them at high prices. As a result of this, a number of people who are unemployed find a source of their daily bread.

4. Bulk Quantity:

ADVERTISEMENTS:

Because railway transportation is cheaper as compared to air and road transport, goods can be carried in bulk quantities as a result of which a lot of time is saved.

It is true that as compared to air transport and road transport, rail transport is easier and cheaper but still it has a few disadvantages.

The Disadvantages of Rail Transport are as Follows:

1. Loss of Goods:

Because goods in bulk quantities are carried chances of goods getting lost are high in case of railway transport as compared to air and road transport.

2. Unsafe for Fragile Items:

Railway transportation is particularly unsafe for carrying fragile items like glass because these items can easily break at times when a train halts unexpectedly of when the train is speeding up at times.

3. Late Bookings:

ADVERTISEMENTS:

Because railway is the cheapest medium of transport, it is hard to find suitable bookings for the transportation of your goods. Railway transport is not suitable in cases of emergency.

4. Unsuitable for Short Distances:

Railway transport is unsuitable for carrying goods at shorter distances; road transport is most suitable in this case.

5. Unsuitable for Rural Areas:

Proper railway system is not build up in the Indian villages as a result of which railway transport is unsuitable in the villages of India. Whatever be the disadvantages of railway transport it was, it is and it will always be the safest and the best means for the transportation of goods.

<h3>What is file?</h3>

A file is a  computer system container for storing data. Files used in computers are similar in characteristics to  paper documents used in libraries and office files. There are different types of files like text files, data files, folders, binary and graphic files and these different types of files store different types of data. A computer's operating system can store files  on optical discs, hard drives,  or other types of storage devices.

In most operating systems, a file must have a unique name within a specific directory. However, when creating a file name, some characters are considered illegal and therefore cannot be used. A file name consists of a name with an extension, also known as a file extension. The file extension is the two to four characters after the period of the full file name.
