You're troubleshooting a malfunctioning notebook computer system. The user has indicated that the LCD screen suddenly became dark and difficult to read while he was downloading a large file through his wireless network card while the system was plugged in at his desk. You've checked the system and determined that the backlight has stopped working.
Required:
What is the MOST likely cause?
Answers
The most likely cause of the LCD screen becoming dark and difficult to read is a faulty backlight inverter or a burned-out backlight bulb.
The fact that the screen suddenly became dark while the user was downloading a large file suggests that the increased power demand from the wireless network card and the downloading process might have caused an electrical surge or overload, resulting in the backlight malfunctioning. The backlight inverter is responsible for supplying power to the backlight bulb, which illuminates the LCD screen. If the inverter fails, it can disrupt the power supply to the backlight, causing it to stop working. Alternatively, the backlight bulb itself may have burned out due to prolonged use or a power surge. In either case, the backlight will need to be replaced to restore proper illumination to the LCD screen.

many years ago, a major corporation purchased and still owns ip addresses within the ipv4 a class range. the corporation uses these addresses to connect to the internet. to which ipv4 address range do they belong?
Answers
If the corporation purchased and still owns IP addresses within the IPv4 A class range, then the addresses would belong to the range of 1.0.0.0 to 127.255.255.255.
These addresses are typically used for larger networks such as corporations and government agencies, and are now in high demand due to the depletion of available IPv4 addresses. The corporation would use these addresses to connect to the internet and to communicate with other devices and networks on the internet.The IPv4 A class range is 1.0.0.0 to 126.255.255.255. Therefore, if a major corporation purchased and still owns IP addresses within the IPv4 A class range, their IP addresses would fall within this range. However, it's important to note that the IPv4 A class range is now mostly depleted, and most IP addresses are now allocated within the IPv4 B and C class ranges.

hard disks have many circular platters inside of them. __________ divide disks into pie-shaped wedges. ________ are concentric circles that radiate out from the center of the disk.
Answers
Hard disks have many circular platters inside of them. **Tracks** divide disks into pie-shaped wedges. **Cylinders** are concentric circles that radiate out from the center of the disk.
Tracks are concentric circles on the surface of each platter, resembling pie-shaped wedges. Each track represents a specific location on the disk where data can be stored or retrieved. Multiple tracks stacked on top of each other across all the platters form a cylinder.
Cylinders, on the other hand, are formed by the tracks that have the same radial distance from the center of all the platters. In other words, a cylinder consists of all the tracks at the same position on each platter. The concept of cylinders is important in hard disk addressing and organization as it allows for efficient storage and retrieval of data.
By using tracks and cylinders, hard disks organize data in a way that enables the read/write heads to access specific locations on the platters quickly and efficiently. The tracks and cylinders provide a systematic structure for data storage and retrieval within the hard disk's magnetic storage medium.

good wireless and better wireless merge to form best wireless. what issue would the federal government be most concerend about in this horizitonal merger
Answers
To avoid the creation of monopolies, the US government closely oversees horizontal mergers. A monopoly occurs when just one or a small number of businesses dominate an industry.
A horizontal merger is a merger or corporate restructuring involving businesses in the same sector. Because there is typically more competition among businesses in the same industry, combining businesses can result in significantly bigger synergies and possible market share gains. One drawback of operating as a sole proprietor is that there is no legal separation between personal and corporate assets, which leaves you open to infinite liability for debts. Your ability to raise money is constrained. You alone are responsible for all daily business choices.

LPARs (Logical Partitions) and logical channel subsystems are defined as b.) resources in IBM mainframe systems.
LPARs allow multiple instances of an operating system to run on a single mainframe by partitioning the resources of the system, such as processors, memory, and I/O devices. Each LPAR can run its own operating system and applications independently of the other LPARs. Logical channel subsystems, on the other hand, are responsible for managing I/O operations between the central processing unit (CPU) and I/O devices in the system.
They provide a layer of abstraction between the physical I/O devices and the software applications that use them, allowing applications to use the devices without having to know their physical location or characteristics.
In summary, LPARs and logical channel subsystems are critical resources in IBM mainframe systems that enable efficient and flexible use of hardware resources while simplifying the management of I/O operations.

Hash Map implementations group key hashes into "buckets". In what situation would there be multiple key hashes in one bucket?
a. When multiple value objects reference the exact same object in memory.
b. When there has been a hash collision.
c. When the Hash Map is optimized for look-up by concurrent threads.
d. When the same key has been inserted more than once.
Answers
A situation where there would be multiple key hashes in one bucket is where there has been a hash collision. The correct answer is b.
A Hash Map uses a hash function to map keys to indices in an array, called "buckets", where the corresponding values can be found. When multiple keys have the same hash value, they are said to have experienced a "hash collision". These keys are then mapped to the same index, or "bucket" in the array, resulting in multiple key-value pairs being stored in the same bucket. This can occur due to the nature of the hash function or due to the number of keys used in the Hash Map being larger than the number of buckets. Collision resolution techniques are used to handle these cases.

The web browser addition that provides links to external programs is a plug-in.
Among the options given, the correct choice for a web browser addition that provides links to external programs is a plug-in. A plug-in is a software component that adds specific features or functionality to a web browser. It extends the capabilities of the browser by allowing it to interact with external programs or applications. Plug-ins are typically designed to handle specific file types or media formats, enabling the browser to open and display content that the browser itself cannot handle natively. Examples of plug-ins include Adobe Flash Player, QuickTime, and Microsoft Silverlight. These plug-ins enable the browser to play multimedia content or display interactive applications that require specific software to run. In contrast, a Java applet is a small program written in the Java programming language that can run within a web browser, but it is not specifically designed for linking to external programs. Extensions and add-ons, on the other hand, typically enhance the browser's functionality or provide additional features but do not directly provide links to external programs.
