Response:
refer to the explanation
Clarification:
Examine the SQL statement shown below:
SELECT c.CustomerName, e.LastName, s.ShipperName, p.ProductName, o.Quantity, od.OrderDate
FROM
Customers c, Employees e, Shippers s, Orders o, OrderDetails od, Products p
WHERE c.customerID = o.customerID AND
e.employeeID = o.employeeID AND
o.orderID = od.orderID AND
od.shipperID = s.shipperID AND
od.productID = p.productID;
The banking system that poses greater risk of vulnerabilities is the one with ten branches dispersed across California, where data resides on a central mainframe located in San Francisco. If the branches do not share data across the network, the risk of hacking is reduced. However, with a network setup, both data sharing and centralized storage increase exposure to unauthorized access.
Answer: Scanners used in supermarkets for barcodes and voice-activated phone menus are not examples of artificial intelligence.
Explanation:
(a) Supermarket barcode scanners can read codes, yet they lack the capability to employ machine learning techniques for learning patterns within the codes. Machine learning is a crucial aspect of artificial intelligence (AI), thus indicating they do not qualify as instances of AI. Likewise, voice-activated menus can only present options and do not carry out any complex tasks.
In contrast, web search engines and internet routing algorithms demonstrate dynamic and intelligent capabilities in processing and delivering information to users.
Hence, these are considered examples of AI.
Response:
a. Current disks do not reveal the actual locations of logical blocks.
Clarification:
Modern disks incorporate scheduling algorithms within the disk drive itself. This presents challenges for operating systems trying to optimize rotational latency. All scheduling methods end up having to perform similarly due to potential constraints faced by the operating system. Disks are typically accessed in physical blocks. Modern technology applies more electronic control to the disk.
