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.

The Chief Information Officer (CIO) has determined the companyâ€™s new PKI will not use OCSP. The purpose of OCSP still needs to

Step2247 [10]

Answer:

B. Implement a key escrow.

Explanation:

A key escrow can be defined as a data security method of storing very essential cryptographic keys.

Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.

As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.

Hence, the cryptographic keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).

In this scenario, the Chief Information Officer (CIO) has determined the company's new public key infrastructure (PKI) will not use online certificate status protocol (OCSP). However, the purpose of online certificate status protocol (OCSP) still needs to be addressed. Thus, what should be implemented is a key escrow because the online certificate status protocol (OCSP) is an internet protocol used for maintaining the security of a server and obtaining a digital certificate that has been revoked.

Which of the following statements comparing debit cards to credit cards is TRUE?

liq [111]

The question has a few multiple choices one can choose from;

A. Debit cards allow you to draw funds directly from your checking account.
B. Debit cards typically offer greater fraud protection than credit cards.
C. Debit cards never require a signature to finalize a purchase like credit cards.
D. Debit cards charge higher interest rates on purchases than credit cards

The Answer is (A) Debit cards allow you to draw funds directly from your checking account.

Checks were replaced by Debit cards as a way of paying for goods or drawing funds from your checking account. Since your debit card comes with your checking account, its simplicity will work nearly everywhere a credit card works. Adding a credit card to your checking account is just adding a layer of complications to your finances.
The fact that a debit card draws on money you already have, those who spend a lot would do well with debit cards and avoid the temptation of credit.
