Why do some systems store the operating system in firmware, while others store it on disk?
For certain devices, such as embedded systems, a disk with a file system may be not be available for the device. In this situation, the operating system must be stored in firmware.

Answer:

If your RAM is full, your computer is slow, and its hard drive light is constantly blinking, your computer is swapping to disk. ... If this is occurring, it's a clear side that your computer needs more RAM – or that you need to use less memory-hungry programs.

Field data retrieval methods are referred to as Accessors, and field data modification methods are referred to as Mutators.

A mutators method is a technique used in computer science to manage changes to a variable. As setter techniques, they are likewise well-known. A getter, which returns the value of the private member variable, frequently follows a setter and together they are referred to as accessors.

According to the encapsulation concept, the mutator method is most frequently employed in object-oriented programming. In accordance with this principle, member variables of a class are made private to hide and protect them from other code. A public member function (the mutator method) is the only way to change a private member variable; it receives the desired new value as a parameter, validates it, and then modifies the private member variable. Assignment operator overloading and mutator methods are similar.

A switch is a piece of network hardware keeps a record of the MAC address of all devices connected to it and uses this information to direct data packets to the appropriate port. The correct option is D.

Using packet switching to receive and forward data to the intended device, a network switch is networking hardware that joins devices on a computer network.

A network switch is a multiport network bridge that transmits data at the OSI model's data link layer using MAC addresses.

By removing the MAC address data from the headers of transmitted Ethernet data packets, switches are able to identify the MAC addresses of the networking devices that are connected to them.

A switch associates the data packet's port with the retrieved MAC address.

Thus, the correct option is D.

With reference to airline industry, they use tags that holds information on passenger's name, destination and flight number for identification.

In the context of the airline industry, there is a similar concept to header information called baggage tags, which are attached to each checked bag as it moves through the airline's handling process. These tags contain information such as the passenger's name, flight number, destination, and a unique identifying number for the bag. This information is used to track the bag's location and ensure that it is loaded onto the correct flight and delivered to the correct destination. Similarly, passengers are assigned boarding passes, which contain information such as the passenger's name, flight number, seat assignment, and departure gate. This information is used to manage passenger flow through the airport and onto the correct flight.

To verify that a numeric positive integer field with a maximum theoretical value of 100 works correctly, you can use a variety of test cases. Some possible test cases include:

The minimum possible value: 0

The maximum possible value: 100

A value near the minimum: 1

A value near the maximum: 99

A value in the middle of the range: 50

A prime number within the range: 67

A composite number within the range: 36

An odd number within the range: 73

An even number within the range: 72

A value that is not a number (e.g. "abc", "1.2", etc.): this is not a valid test case, as the field is for numeric positive integers only.

It is generally a good idea to test the boundaries and edges of the expected input range, as well as some values within the range, to ensure that the field is functioning correctly.

Suppose a variation of FFS includes in each inode 12 direct, 1 indirect, 1 double indirect, 2 triple indirect, and 1 quadruple indirect pointers. Assuming 6KB blocks and 6-byte pointers.

a. Largest file that can be accessed via direct pointers only is 12 direct pointers per inode × 6KB/block = 72KB.

b. The maximum file size this index structure can support is: (12 × 6 KB) + (2 × 1024 × 6 KB) + (2 × 1024^2 × 6 KB) + (1024^3 × 6 KB) = 12 × 6 KB + 2 × 6 MB + 2 × 6 GB + 6 TB = 6.384 TB.

FFS is a file system used by BSD and derived operating systems like FreeBSD, NetBSD, OpenBSD, and macOS. The term FFS stands for Fast File System.

The one that is not a use of a hash function is Lossy compression to reduce file sizes when fidelity is not required. Option C is correct.

The use of a hash function is to generate a unique fixed-size output (hash value) from an input of variable size. This output is used for various purposes, such as data indexing, security, and digital signatures.

Out of the given options, program execution optimization, checksums for integrity checking, and error correcting codes for data transmission optimization all make use of hash functions. However, lossy compression to reduce file sizes when fidelity is not required does not involve hash functions.

Instead, lossy compression algorithms discard some data to reduce file size, which can result in a loss of information. Hence, lossy compression is not a use of a hash function.

Paper jams are usually caused by dirty, worn, or damaged rollers. Paper pickup rollers can be cleaned with alcohol or replaced if they are worn out. Similarly, separation pads can cause paper jams. The separation pad is responsible for ensuring that the paper feed rollers only take one page at a time. If the separation pad is worn or sticky, it will cause multiple pages to be fed through the printer at once. Separation pads can usually be cleaned or replaced if they are worn out.Answer in 200 words:Therefore, the technician should check the pickup rollers and separation pad first for paper feeding issues.

A laser printer has a lot of moving parts that are designed to work together. The paper feeder is one of these parts, and it's crucial to ensure that it's in good working condition. Laser printers are known for their ability to handle a lot of paper, and it's not uncommon for them to be used in environments where they're frequently printing. This means that the paper feeder is likely to get a lot of wear and tear, which can lead to problems like paper jams.If the paper feeder is not working correctly, it can cause paper jams, and it can also damage the printer itself. This is why it's essential to check the paper feeder regularly, and to ensure that it's functioning correctly. The technician should start by checking the pickup rollers and separation pad, as these are the most common causes of paper jams in a laser printer. If the issue is not resolved, the technician may need to investigate other parts of the printer, such as the transfer belt or toner cartridge, but it's essential to start with the paper feeder.
