How is an interpreter different from a compiler?

lyudmila [28]

Answer:

An interpreter is quite different from a complier due to the following statement below:

O. An interpreter translates and executes code line by line, while a compiler translates all code at once so that it is ready to be executed at any time.

Explanation:

For an interpreter, it works in translating and execution of the codes line after another line. In a situation where there is a mistake in the code, the next line would not be able to be executed, but rather display error message. On the other hand, compiler translate all codes at once and execute them as a single work.

<em>During its translation of the codes in compiler, should there be any error, it would not be able to execute despite the fact that, the error might be in the last line of the code.</em>

2. A particular brand of mobile phone/PDA

3. A network that operates over a limited distance, usually for one or a few users

1. Bluetooth

2. PAN

3. Blackberry

Answer:

1. Bluetooth 2. Blackberry . 3. PAN

Explanation:

1. Bluetooth is a wireless technology standard, used in order to exchange data between mobile devices, like smartphones, tablets, headsets, wearables, over short distances in a one-to-one fashion (which means that it is not possible to build a network based in Bluetooth).

2. Blackberry is a brand of mobile phones/PDAs, very popular a decade ago, because it was the first one to allow mobile users to access e-mails and messages from anywhere, at any time.

3. PAN (Personal Area Network) is an ad-hoc network that it is only available for data exchange at a very short distance, within the reach of a person, i.e. a few meters as a maximum.

It is thought to allow someone to interact with his nearest environment (laptop, tablet, PDA) and it can be wireless (like Bluetooth) or wired (via USB cables).

CAR_SALE (Car_no, Date_sold, Agent_no, Commission_pct, Discount_amt)

serg [7]

1NF

In 1NF the relation should follow atomicity that means no repeating groups

In the relation there is no repeating groups

So

the relation is in 1NF

2NF

In 2NF, the relation should be in 1NF and each non prime

attribute must depend on primary key and No Partial dependency

Commission% is functional dependent on Salesperson# which is only part of the primary key.

So

relation is not in 2NF

3NF

In 3NF, the relation should be in 2NF and any NON prime attribute should not describe any non prime attribute.

Already we know relation is not in 2NF

there is a non prime attribute date_sold that describe another non prime attribute Discount_amt,

the relation is not in 3NF

Finally we come to. Know

the relation satisfies only 1NF

NORMALIZATION

The relation is not in 2NF

Decompose the relation CAR_SALE

CAR_SALES (Car#, Date_sold, Salesperson#, Discount_amt)

SALESCOMM (Salesperson#, Commission%)

CAR_SALES and SALESCOMM are in 2NF

In 3NF, the relation should be in 2NF and any NON prime

attribute should not describe any other non prime attribute

SALESCOMM relation is in 3NF

but CAR_SALES is not in 3NF the reason is that there is a

non prime attribute Date_sold that describes another non prime attribute Discount_amt.

So, decomposing the relation

CARSALEDATE (car#, salesperson#, Date_sold)

DATEDISS(Date_sold, discount_amt)

The relations CARSALEDATE

SALESCOMM

DATEDIS are in 3NF
