Answer:

16 RAM chips

Explanation:

To calculate the number of RAM chips needed, we divide the total size of the main memory by the size of each RAM chip. Hence:

Number of RAM chips required = Main memory size / size of one RAM

2M = 2²¹, 16 = 2⁴, 256K = 2¹⁸, 8 = 2³

Hence:

Number of RAM chips required = (2²¹ * 2⁴) / (2¹⁸ * 2³) = 2⁴ = 16

Therefore 16 RAM chips are necessary

Drag each statement to the correct location.

VMariaS [17]

Answer:

$(a)\ 222_{10} = DE_{16}$ --- True

$(b)\ D7_{16} = 11010011_2$ --- False

$(c)\ 13_{16} = 19_{10}$ --- True

Explanation:

Required

Determine if the statements are true or not.

$(a)\ 222_{10} = DE_{16}$

To do this, we convert DE from base 16 to base 10 using product rule.

So, we have:

$DE_{16} = D * 16^1 + E * 16^0$

In hexadecimal.

$D =13 \\E = 14$

So, we have:

$DE_{16} = 13 * 16^1 + 14 * 16^0$

$DE_{16} = 222_{10}$

Hence:

(a) is true

$(b)\ D7_{16} = 11010011_2$

First, convert D7 to base 10 using product rule

$D7_{16} = D * 16^1 + 7 * 16^0$

$D = 13$

So, we have:

$D7_{16} = 13 * 16^1 + 7 * 16^0$

$D7_{16} = 215_{10}$

Next convert 215 to base 2, using division rule

$215 / 2 = 107 R 1$

$107/2 =53 R 1$

$53/2 =26 R1$

$26/2 = 13 R 0$

$13/2 = 6 R 1$

$6/2 = 3 R 0$

$3/2 = 1 R 1$

$1/2 = 0 R1$

Write the remainders from bottom to top.

$D7_{16} = 11010111_2$

<em>Hence (b) is false</em>

$(c)\ 13_{16} = 19_{10}$

Convert 13 to base 10 using product rule

$13_{16} = 1 * 16^1 + 3 * 16^0$

$13_{16} = 19$

Hence; (c) is true

Marina86 [1]

Many <u>online training</u> classes for certification are made available for students on the Internet and by many companies that have set up intranets within their organizations.

Certification can be defined as a recognition that is given to an individual (student) for the completion of a specific course of study and passing an examination. Thus, it usually issued to certify that an individual is a professional in a particular course of study.

Some examples of certifications that are issued to an individual (student) include the following:

CCNA

Comptia A+

HSE I and II

In this context, many companies with intranet facilities within their organizations offer <u>online training</u> classes for certification by making them available for students over the Internet.

A three-tier design includes a middle layer between the client and server that processes the client requests and translates them

devlian [24]

Answer:

a. True

Explanation:

The three tiers in a three-tier architecture are:

Presentation Tier: Occupies the top level and displays information related to services available on a website. This tier communicates with other tiers by sending results to the browser and other tiers in the network.

Middle Tier: Also called the application tier, logic tier, business logic or logic tier, this tier is pulled from the presentation tier. It controls application functionality by performing detailed processing.

Data Tier: Houses database servers where information is stored and retrieved. Data in this tier is kept independent of application servers or business logic.

The definition of network is:

kondaur [170]

$\text{Hello there!}$

<u>Networks were originally used as a government weapon 61 years ago</u> to <u>communicate information</u> such as data and research. However, individual networks were eventually discontinued by the government and made open to the public to use for things such as PAN, LAN, MAN, WAN, SAN, and so on.

<u>Our internet today is capable of communicating with bilions of computers.</u> This is possible due to your modem using radio wave-like speeds to connect to your ISP. Your ISP then connects to a larger network, which is connecting to thousands of other networks. You see, <u>the internet is just a large network of networks that are connected through very fast radiowaves</u>. However, it is not just a single network being used anymore; it's thousands of them. The term, "internet" was used to describe this large selection of networks. In short, <u>B</u><u> would be incorrect. </u>

The worldwide web is a protocol used by the internet to connect to select websites favourably from whoever's using it. This obviously would not define the network, as this is something that's used by it. Furthermore, <u>A</u><u> would not be correct.</u>

As described already, the network was a selection of computers used to communicate information to each other. <u>C </u><u>would not be correct </u>as it states that there is only one computer being used.

$\fbox{Therefore, D would be the correct answer.}$
