When the store-and-forward method of switching is in use, what part of the Ethernet frame is used to perform an error check?
Answer:
Source MAC address in the header
Explanation:
Store-and-Forward Switching is a Layer 2 switching method and it means that the LAN switch copies each complete frame into the switch memory buffers and computes a cyclic redundancy check (CRC) for errors. CRC is an error-checking method that uses a mathematical formula, based on the number of bits (1s) in the frame, to determine whether the received frame is errored. If a CRC error is found, the frame is discarded. If the frame is error free, the switch forwards the frame out the appropriate interface port
The Ethernet frame uses the FCS (Frame Check Sequence) for error checking when the store-and-forward switching method is in use.
When the store-and-forward method of switching is in use, the part of the Ethernet frame used to perform an error check is the FCS (Frame Check Sequence).This FCS, a field within the Ethernet frame, contains error-checking information that allows the receiving device to detect any transmission errors.By comparing this FCS value with the received data, the device can determine if the information in the frame is accurate or if errors have occurred.Stephanie is a zoologist who loves the outdoors and often travels the world researching wildlife and serving as a consultant it zoos.

When replacing a system board in a laptop, which feature is a must?
Dual core CPU
Having the integrated peripherals in the same locations as the old system board
More RAM
Quad core CPU
Answer:
Having the integrated peripherals in the same locations as the old system board
Explanation:
System board is the printed circuit board that is used to connect the peripheral devices. It provides the slots and ports to connect the peripherals devices.
If there is a need to replace the system board of the laptop. You can change the system board. On new system board, all the peripherals that are installed on previous (old) system board should be placed on new system board. As the system requirements are same, only printed circuit board of the system is changed.
The new system board is replica of the previous board so, we can not change peripheral of the system boards.
When it comes to data storage, if a user wants striping and backup, which RAID will do both?
RAID 0
RAID 1
RAID 5
RAID 10
RAID 10 is the correct RAID level that provides both striping for performance and mirroring for data backup, meeting the user's requirements.
When it comes to data storage, if a user desires both striping for performance and backup for redundancy, the appropriate RAID level to choose would be RAID 10 (also known as RAID 1+0). Here's a brief explanation of why the other RAID levels do not meet both criteria:RAID 0: Offers striping but no redundancy for backup.RAID 1: Offers redundancy for backup but no striping.RAID 5: Offers striping and parity for redundancy, but the redundancy is not a full backup; it's designed to survive a single drive failure.RAID 10: Combines the benefits of RAID 0 and RAID 1, providing both striping and mirroring for backup.Therefore, RAID 10 is the optimal choice for users seeking both performance enhancements via striping and data protection through backup.Given a variable temps that refers to a list, all of whose elements refer to values of type float , representing temperature data, compute the average temperature and assign it to a variable named avg_temp . Besides temps and avg_temp , you may use two othervariables -- k and total .
My solution below didn't work. I wonder how to go about this problem.
temps = []
avg_temp = 0.0
total = 0.0
for k in range(temps):
total += k
avg_temp = total/len(temps)
Answer:
The problem of the question code is as follows:
Explanation:
There must be the items in the list: The above question code is in python language. The temps are a list type variable that is used to hold the collection of items or value. But in the above code, there is no item in the K list. So first remove this problem with the help of add the value on the list. There are two ways to add value to the list:- 1. Define the static list element by writing like "temps=[1.2,2.4,4.5]". and 2. Take input from the user and then add by "temps.append(item)".The syntax of the for loop: The syntax of the for loop is not right because it holds the "range" keyword which is written when we give the numeric value like, "for x in range(2)" or "for x in range(1,2)". So to correct for syntax the user needs to write "for k in temps:".If the user removes the above-defined error from the code then the above code will run correctly
The code segment you've provided contains a small mistake in the loop that iterates through the list temps. Instead of using range(temps), you should iterate directly over the elements in temps using for k in temps:
temps – a list with temperature data as floating-point numbers
total – to hold the sum of all temperatures
k – to refer to each temperature in the list during iteration
avg_temp – to store the computed average temperature
The correct code should look like this:
temps = [/* list of float values */]
avg_temp = 0.0
total = 0.0
for k in temps:
total += k
avg_temp = total / len(temps)
Here, the variable k will take on the value of each element in temps as we iterate through the list, adding each temperature to total. After the loop, we divide total by the number of elements in temps to get the average temperature. This will correctly compute avg_temp as long as temps is not empty.

You are troubleshooting a network issue on a client computer and discover that the network card has an IP address of 169.254.196.200. What does this mean?
Answer:
Automatic Private IP Addressing (APIPA)
Explanation:
This usually means no static IP address is assigned to the computer. Therefore it cannot connect to the Dynamic Host Configuration Protocol (DHCP). It thus uses Automatic Private IP Addressing (APIPA)(which usually ranges from 169.254.0.1 to 169.254.255.254) to configure itself.
To resolve this, disconnect the computer from the network, assign or change the Static IP and reconnect. Alternately you can reset the Modem/Router.
An IP address of 169.254.196.200 indicates that the computer's network card has been assigned an Automatic Private IP Address (APIPA), which is used when it cannot reach a DHCP server.
When a computer is assigned an IP address of 169.254.196.200, it means that the network card has been assigned an Automatic Private IP Address (APIPA). APIPA is used by Microsoft Windows operating systems when the network card is set to obtain an IP address automatically, but the Dynamic Host Configuration Protocol (DHCP) server is not available or cannot be reached. In this situation, the operating system assigns an IP address in the 169.254.x.x range, enabling the computer to communicate with other devices on the same local network subnet, despite not being able to access the broader internet or external networks.
This situation is often a sign that there is a problem with the network's DHCP configuration or with the network itself. To resolve the issue, you would typically check the network connection, verify the DHCP server status, or review the network card settings on the impacted computer. The purpose of APIPA is to allow local network communication to continue until the DHCP issue can be resolved.

Individuals and businesses have concerns about data security while using Internet-based applications. Which security risk refers to unsolicited bulk messages sent via the Internet? Refers to unsolicited bulk messages sent via the Internet.
Answer:
Spam
Explanation:
Spam is unsolicited bulk messages, that is, messages sent to multiple recipients who did not ask for them. The problems caused by spam are due to the combination of the unsolicited and bulk aspects; the quantity of unwanted messages swamps messaging systems and drowns out the messages that recipients do want. Spam has been a problem in many different media, and invariably arises whenever a medium allows people to send many messages without per-message charges.
Determine the "M" value and number of data bits that can be represented by a single symbol using ASK where the possible amplitude values per symbol can be {0v, +1v, +2v, +3v, +4v, +5v, +6v, +7v}. a. M=2, N=1 bit per symbol b. M=4, N=2 bit per symbol c. M=6, N=3 bit per symbol d. M=8, N=3 bit per symbol
Answer:
d. M=8, N=3
Explanation:
The number of messages (M) that can be sent is 8. The eight messages are the listed amplitude values.
The number of bits per symbol (N) is log2(M) = log2(2^3) = 3.
M=8 messages can be sent, so N=3 bits per symbol.

____ twisted pair is the least quality twisted pair wire that should be used in a data/voice application.
Answer:
Category 5 (Cat 5) twisted pair is the least quality twisted pair wire that should be used.
Explanation:
The reason is as follows:
Category 1 twisted pair is not suitable for transmitting data but comes in handy for telephone communications. Hence, it should not be used in a data/voice application.Category 2 twisted pair is suitable for data transmission, however, it can only transmit at 4Mbps which is very slow. Hence, it should not be used in a data/voice application.Category 3 twisted pair can transmit data with speed reaching 10Mbps which is slow for voice/data communication.Category 4 twisted pair can transmit data with speed reaching 16Mbps and is used in token ring networks. It is slow for communicating in a voice/data application.Category 5 twisted pair is the least qualified to be used in a voice/data application because it can transmit data at speeds that reach 100Mbps.Hence, Cat 5 or Category 5 twisted pair is the least quality twisted pair that should be used in a data/voice application.
Final answer:
The correct answer is "Category 5 (Cat5)" The minimum quality twisted pair wire that should be used in data/voice applications is Category 5 (Cat5), though Cat5e and higher are preferred due to better performance.
Explanation:
The Category 5 (Cat5) twisted pair is the least quality twisted pair wire that should be used in a data/voice application. This standard is considered the minimum for supporting speeds up to 100 Mbps. Although it is an older category and has been superseded by Cat5e, Cat6, and higher categories that provide faster speeds and better crosstalk protection, Cat5 is still used in some installations where higher specifications are not necessary or cost is a limiting factor.
For most modern applications, however, Cat5e is the preferred minimum as it supports speeds up to 1 Gbps which is more suitable for current demands in network environments. Cat6 and above offer even better performance, supporting higher speeds and frequency ranges, which are important as demand for bandwidth continues to grow with the proliferation of connected devices and data-intensive applications.
DMMs of average quality or better are "fused," meaning that one or more "fast-blow" fuses are included inside the DMM. If the ________ is too ______, the fuse will blow, protecting the meter.
Answer:
If the amperage is too high, the fuse will blow, protecting the meter.
Explanation:
Fuses are wires to prevent the destruction of electrical equipment. This destruction is caused by power surges
Digital Multimeters or DMMs are better fused, to avoid damage. This damage can occur if the amperage is too high and there is no fuse in the multimedia.
The fuse will get damaged first, therefore, disrupt the flow of current to the electronics.
