A _________ conversion involves running the old and new systems simultaneously for a time, which is is rarely used, since it impractical for customer-facing e-commerce systems.
Small conversions require running the old and new systems simultaneously for a period of time, but they are rarely used because they are impractical for customer-facing e-commerce systems.
Conversion Tactics:
Both conversion tactics aim to make it easier for users to adapt to the new system. The old system is "unplugged" and the new system is turned on when converting directly. The new system must be used by users; there is no other option.
The old system is briefly used in the parallel conversion plan while the new system is turned on. Since there is no backup in the event that significant system flaws are found, the direct approach is riskier.
In the event that a critical flaw in the new system is found, the parallel conversion will continue to operate the old system. However, it is crucial to take into account the expense and additional work associated with using both systems at once.

which protocol is responsible for delivering packets to the right computers?
The Internet Protocol (IP) is responsible for delivering packets to the right computers on a network.
What is the IP?IP is a network layer protocol that provides a unique address, known as an IP address, to every device connected to the network.
When a packet is sent, it contains both the source and destination IP addresses, allowing routers and other networking devices to direct the packet to its intended destination based on the destination IP address.
In this way, IP provides the necessary addressing and routing functions to ensure packets are delivered to the correct device on a network.

DML triggers can be used to produce automatic responses if data have been altered. SQL code and DDL triggers may also be used, but they are not specifically designed for monitoring and responding to changes in data.
Mirroring is a data replication technology that involves copying data from one server to another without the use of triggers. It ensures data redundancy by maintaining an identical copy of the data on multiple servers, providing a failover mechanism in case of server failure. Mirroring is commonly used for high availability and disaster recovery purposes in database systems.

At what layer do routers allow the datagram to hop from the source to the destination, one hop at a time? group of answer choices data link
Routers operate at the network layer (layer 3) of the OSI (Open Systems Interconnection) model, which is responsible for the transmission of data between different networks. The network layer is responsible for logical addressing and routing, enabling routers to make decisions about how and where to forward packets based on their destination IP address.
When a packet arrives at a router, it examines the destination IP address and consults its routing table to determine the best path for the packet to reach its destination. The router then forwards the packet to the next hop on that path, which may be another router or the final destination device.
By allowing the datagram to hop from the source to the destination, one hop at a time, routers enable packets to traverse multiple networks and reach their intended destinations even if those networks use different protocols or technologies. Without routers, data would be confined to a single network and could not be transmitted beyond its boundaries.

where in the windows registry would you store a key that starts an executable
When considering where in the Windows registry you would store a key that starts an executable, the appropriate location is the "Run" key.
The "Run" key is located in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run for all users or HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run for the current user.Explanation:The Windows registry is a hierarchical database that stores low-level configuration information for the Microsoft Windows operating system. The registry includes settings for drivers, operating system components, installed software, and various other parameters. The registry can be edited manually, but it is not recommended for most users as errors can cause serious problems.
A startup program is an executable program that runs automatically when you start your computer. In order to run automatically, the program needs to be added to the Windows registry in a specific location. The appropriate location is the "Run" key. The "Run" key is located in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run for all users or HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run for the current user.When a program is added to the "Run" key, it will automatically start whenever you start your computer. This can be useful for programs that you use frequently and want to have available right away. However, too many programs in the "Run" key can slow down your computer's startup time and overall performance. Therefore, it is important to be careful when adding programs to the "Run" key.Conclusion:In conclusion, the appropriate location in the Windows registry to store a key that starts an executable is the "Run" key, which is located in the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run for all users or HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run for the current user.

all network switches require substantial configuration before they can be put into operation in a network. true false
The statement "All network switches require substantial configuration before they can be put into operation in a network" is partially true. However, a long answer would be required to explain why. Here's why:Explanation:Most network switches require some configuration before they can be used in a network.
There are, however, several unmanaged switches available on the market that do not require configuration, making it simple to add them to a network quickly. Furthermore, several switches are now designed to be simple to set up and operate with no technical knowledge required. On the other hand, many network switches are quite complicated and will require considerable configuration to function properly.
They can have dozens of ports and advanced features such as VLAN tagging and port mirroring, and setting up these features can take some time and expertise. Some switches come with pre-installed templates, making it easier for switches require some degree of configuration, there are exceptions to this rule, and the amount of configuration required varies depending on the type of switch.

A beam of light travels in air and then passes through a piece of glass at an angle of 45 degrees to the normal. As the light passes from the air into the piece of glass, the light ray is bent, what is the angle of refraction measured from the normal?
Answer:
The angle of refraction measured from the normal is approximately 28.13°
Explanation:
The angle of refraction is the angle made by the refracted ray and the normal line drawn at the point where the ray passes through the interface of the two mediums
According to Snell's law, we have;
\(_1 n_2 = \dfrac{n_1}{n_2} = \dfrac{sin \, \theta _2}{sin \, \theta _1}\)
n₁·sin (θ₁) = n₂·sin(θ₂)
Where;
₁n₂ = The refractive index of air to glass = 1.5
n₁ = The refractive index of air = 1
n₂ = The refractive index of glass ≈ 1.5
θ₁ = The angle of incidence = 45°
θ₂ = The angle of refraction measured from the normal
Therefore, we have;
1/1.5 = sin(θ₂)/sin(45°)
sin(θ₂) = sin(45°)/1.5 = (√2)/2/(3/2) = (√2)/3
∴ θ₂ = arcsin((√2)/3) ≈ 28.13°
The angle of refraction measured from the normal = θ₂ ≈ 28.13°.
