Explanation:

Wireless Security:

In a bid to examine the network you can use ipconfig /all command in windows or in the event where you are a linux user type in ifconfig to view all the configuration details of your network such as

indows IP Configuration

Host Name . . . . . . . . . . . . : myvpc-hb

Primary Dns Suffix . . . . . . . : example.com

Node Type . . . . . . . . . . . . : Hybrid

IP Routing Enabled. . . . . . . : Yes

Ethernet adapter Local Area Connection:- - - - - -

Connection-specific DNS Suffix . :- - - - - -

Description . . . . . . . . . . : Intel 68540-Based PCI Express Fast Ethernet Adapter

Physical Address. . . . . . . . . : 00-03-AA-BC-CA-8F

Autoconfiguration Enabled . . . . : Yes

Link-local IPv6 Address . . . . . : fe65::ab56:ccb9:320c:524d%8(Preferred)

IPv4 Address. . . . . . . . . . . : 192.168.45.111(Preferred)

Default Gateway . . . . . . . . . : 192.168.15.1

DHCP Server . . . . . . . . . . . : 192.168.15.1

DHCPv6 IAID . . . . . . . . . . . : 201327615

Note: If you want to deeply examine the your network and to find security model go with Wireshark application.It will help you to capture the data packets easily using GUI.Also it will provide other details like transmission control protocols,etc.

To take your network to highest level i.e. to make it more secure you can use:

1.Firewalls like application gateways,packet filtering,hybrid systems.

2.Crypto cable routers

3.Virtual private networks, etc.

Estimation of cost and the time to increase the level is solely depends on the type of the architecture you want to use for the network building structure.Also the size of the network will be responsible for the cost and time.

In case of any attack on your computer it depends on the size of the data on the computer disc and the bandwidth of the network to which your computer is connected to replace all data. The faster the bandwidth of the network,faster the data replacement rate.

A _____ is relatively inexpensive to install and is well-suited to workgroups and users who are not anchored to a specific desk

KengaRu [80]

Answer:

B) wireless local area network (WLAN)

Explanation:

WLAN which fully meaning is WIRELESS LOCAL AREA NETWORK is a network provider that enables two or more mobile phone user , desktop or computer user to connect and have access to the internet by simply connecting to the local area wireless network and this type of wireless network are more cheaper to install.

Example of where WIRELESS LOCAL AREA NETWORK can be found are : School building, Office building, School campus, home, among others.

A common fallacy is to use MIPS (millions of instructions per second) to compare the performance of two different processors, an

yulyashka [42]

The question is incomplete. It can be found in search engines. However, kindly find the complete question below:

Question

Cites as a pitfall the utilization of a subset of the performance equation as a performance metric. To illustrate this, consider the following two processors. P1 has a clock rate of 4 GHz, average CPI of 0.9, and requires the execution of 5.0E9 instructions. P2 has a clock rate of 3 GHz, an average CPI of 0.75, and requires the execution of 1.0E9 instructions. 1. One usual fallacy is to consider the computer with the largest clock rate as having the largest performance. Check if this is true for P1 and P2. 2. Another fallacy is to consider that the processor executing the largest number of instructions will need a larger CPU time. Considering that processor P1 is executing a sequence of 1.0E9 instructions and that the CPI of processors P1 and P2 do not change, determine the number of instructions that P2 can execute in the same time that P1 needs to execute 1.0E9 instructions. 3. A common fallacy is to use MIPS (millions of instructions per second) to compare the performance of two different processors, and consider that the processor with the largest MIPS has the largest performance. Check if this is true for P1 and P2. 4. Another common performance figure is MFLOPS (millions of floating-point operations per second), defined as MFLOPS = No. FP operations / (execution time x 1E6) but this figure has the same problems as MIPS. Assume that 40% of the instructions executed on both P1 and P2 are floating-point instructions. Find the MFLOPS figures for the programs.

Answer:

(1) We will use the formula:

CPU time = number of instructions x CPI / Clock rate

So, using the 1 Ghz = 10⁹ Hz, we get that

CPU time₁ = 5 x 10⁹ x 0.9 / 4 Gh

= 4.5 x 10⁹ / 4 x 10⁹Hz = 1.125 s

and,

CPU time₂ = 1 x 10⁹ x 0.75 / 3 Ghz

= 0.75 x 10⁹ / 3 x 10⁹ Hz = 0.25 s

So, P2 is actually a lot faster than P1 since CPU₂ is less than CPU₁

(2)

Find the CPU time of P1 using (*)

CPU time₁ = 10⁹ x 0.9 / 4 Ghz

= 0.9 x 10⁹ / 4 x 10⁹ Hz = 0.225 s

So, we need to find the number of instructions₂ such that CPU time₂ = 0.225 s. This means that using (*) along with clock rate₂ = 3 Ghz and CPI₂ = 0.75

Therefore, numbers of instruction₂ x 0.75 / 3 Ghz = 0.225 s

Hence, numbers of instructions₂ = 0.225 x 3 x 10⁹ / 0.75 = 9 x 10⁸

So, P1 can process more instructions than P2 in the same period of time.

(3)

We recall that:

MIPS = Clock rate / CPI X 10⁶

So, MIPS₁ = 4GHZ / 0.9 X 10⁶ = 4 X 10⁹HZ / 0.9 X 10⁶ = 4444

MIPS₂ = 3GHZ / 0.75 X 10⁶ = 3 x 10⁹ / 0.75 X 10⁶ = 4000

So, P1 has the bigger MIPS

(4)

We now recall that:

MFLOPS = FLOPS Instructions / time x 10⁶

= 0.4 x instructions / time x 10⁶ = 0.4 MIPS

Therefore,

MFLOPS₁ = 1777.6

MFLOPS₂ = 1600

Again, P1 has the bigger MFLOPS

In the Sender Message Channel Receiver (SMCR) model, the ______ is the large, bureaucratic organization that produces messages.

mafiozo [28]

Answer:

Sender.

Explanation:

The Sender Message Channel Receiver (SMCR) model of communication was developed and created by David Berlo in 1960. SCMR was developed from the Shannon-Weaver model of communication of 1949.

The SCMR model of communication comprises of four (4) main components and these are;

1. Sender (S): this is typically the source of information (message) or the originator of a message that is being sent to a receiver. Thus, they are simply the producer of a message.

2. Channel (C): this is the medium used by the sender for the dissemination or transmission of the message to the recipient. For example, telephone, television, radio, newspapers, billboards etc.

3. Message (M): this is the information or data that is being sent to a recipient by a sender. It could be in the form of a video, audio, text message etc.

4. Receiver (R): this is typically the destination of information (message) or the recipient of a message that is being sent from a sender.

Hence, in the Sender Message Channel Receiver (SMCR) model, the sender is the large, bureaucratic organization that produces messages.

Additionally, encoding is the process of transmitting the message from the sender to the recipient while decoding is the process of interpreting the message that is being received from a sender.
