Enumerate a couple of reasons why it would be impracticable for the external devices to be connected directly to the processor or the system bus

Answers

Answer 1

Answer:

(a) Difference in data transfer rates

(b) Difference in word lengths

(c) Different peripherals with different modes of operation

Explanation:

There are several reasons. Some of them have been listed in the explanation section. A brief explanation is as follows

(a) Difference in data transfer rates

Some peripherals have fast transfer rate while some have slow transfer rates compared to the processor they are being connected to. This difference in the rates implies that a high speed system bus will find it difficult to communicate with a (say) low speed peripheral.

(b) Difference in word lengths

Another consideration is the word lengths. Often times, peripherals and the bus they are being connected with will have a different word lengths.

(c) Different peripherals with different modes of operation

In computer architecture, a processor can not be used to interact with peripheral of different mode of operations. In other word, each peripheral have its own mode and will require different means of connection.

You are an IT consultant. You are visiting a new client's site to become familiar with their network. As you walk around their facility, you note the following: When you enter the facility, a receptionist greets you and directs you down the hallway to the office manager's cubicle. The receptionist uses a notebook system that is secured to her desk with a cable lock. The office manager informs you that the organization's servers are kept in a locked closet. Only she has the key to the closet. When you arrive on site, you will be required to get the key from her to access the closet. She informs you that server backups are configured to run each night. A rotation of external USB hard disks are used as the backup media. You notice that the organization's network switch is kept in an empty cubicle adjacent to the office manager's workspace. You notice that a router/firewall/content filter all-in-one device has been implemented in the server closet to protect the internal network from external attacks. Which security-related recommendations should you make to this client

• Relocate the switch to the locked server closet

Explanation:

Based on the information given, the security-related recommendations that should be made to this client include:

Therefore, it should be moved to the locked server closet to prevent external attack.

• Control access to the work area with locking doors and card readers- Thus us necessary so that the work area won't be accessible to just anybody.

What is an example of a composite key in a database table?

InvoiceID

ProductID
OrderID + ProductID

Answers

Answer:

b

Explanation:

OrderID + ProductID is an example of a composite key in a database table. The correct option is 4.

What is composite key?

A composite key is a key in a database table that consists of two or more columns that uniquely identify each row.

In a database table, a composite key is the combination of OrderID and ProductID in a table that tracks sales transactions.

Because a single order can contain multiple products and multiple orders can contain the same product, neither column can uniquely identify a row by itself.

However, by combining the two columns, each row can be uniquely identified, ensuring that the data is accurate and complete.

Similarly, a combination of CustomerID and ProductID might be used in a sales system to track the products purchased by each customer.

Thus, the correct option is 4.

A cheetah has a mass of 50kg and can accelerate at 10 m/s2. This is equal to 500 Newtons which is the force the cheetah creates to run. Let's calculate how much work the cheetah does and how much power it generates when it runs 50 meters in 3 seconds.

Step 1: Determine how much work is done (measured in joules).

Multiply the force by the distance 500N×50meters= _______ joules



Step 2: Determine the power (measured in Watts).

Divide the work by the time it took to do the work 25,000joules÷3s.= _______ watts

Answers

Answer:

often, work done= Force<<* distance

so work done=500N * 50m

work done=25000J

also, Power=work done/Time taken

Power=25000J/3sec

Power=8333.333.....

How does a filmmaker decide which events to include in a documentary?

Answers

Answer:

A documentary is a film based on facts in which the maker tries to portray an aspect of reality, such as politics, science, society or history, nature or the personal perception of the documentary maker.

Documentaries are informative in nature. Sometimes documentaries attempt to provide an objective picture of a subject. There is a lot of debate about what is objective, because the documentary maker chooses his images from reality, which is in itself a subjective act. In a creative author's documentary, the emphasis is on the subjective vision of the filmmaker.

Therefore, the documentary maker will select the events to include in the documentary according to the approach he or she wants to give to it, be it objective or subjective.
