If a magnetic disc has 100 cylinders, each containing 10 tracks of 10 sectors and each sector can contain 128 bytes, what is the maximum capacity of the disk in bytes
Answer:
The maximum capacity of disc is 12,80,000 bytes.
Step-by-step explaination:
Given a magnetic disc having 100 cylinders & each containing 10 tracks of 10 sectors. Hence, total no. of sectors in magnetic disc are [tex]100\times 10\times 10[/tex]=10000 sectors
Each sector contain 128 bytes.
we have to find the maximum capacity which can be calculated as
Maximum capacity = No. of sectors[tex]\times[/tex]capacity of sectors
= 10000[tex]\times[/tex]128
= 12,80,000 bytes
The maximum capacity of the disk is 1280000 bytes.
Further Explanation:
It is given that a magnetic disc having 100 cylinders and each cylinder containing 10 tracks of 10 sectors.
Therefore, the number of sectors in the magnetic disc is the product of total cylinders, tracks and sectors.
The number of sectors is calculated as,
[tex]\begin{aligned}\text{Total sectors}&=100\times 10\times 10\\&=10000\end{aligned}[/tex]
The maximum capacity of the magnetic disc is the product of number of sectors in magnetic disc and capacity of a sector.
[tex]\begin{aligned}\text{maximum capacity}&=10000\times 128\\&=1280000\end{aligned}[/tex]
Thus, the maximum capacity of the magnetic disc with 10000 sectors and capacity of 128 bytes is 1280000 bytes.

What software emulates the hardware on which an operating system runs?
A hypervisor or virtual machine monitor (VMM) is software that emulates the hardware for an operating system, facilitating server virtualization by allowing multiple OS to run on the same physical hardware.
The software that emulates the hardware on which an operating system runs is known as a virtual machine monitor (VMM) or hypervisor. A hypervisor creates a virtual version of a computer system that allows multiple operating systems to share the same physical hardware resources.
This technology is essential for server virtualization, helping to reduce the need for excess physical servers and allowing for efficient resource management. There are two main types of virtualization: hardware virtualization and software virtualization. Hardware virtualization is typically more efficient as it directly manages the hardware resources without the need of a host operating system.
In contrast, software virtualization runs on top of an existing operating system, utilizing more system resources but offering simpler management.

Why do computers use binary instead of decimal?
Computers use binary because it corresponds to the two possible states of electronic components: on and off, making data processing straightforward and reliable. Binary systems provide simpler storage, vast representational scope, and security benefits particularly evident in encryption key possibilities. The digital nature of binary is echoed in biological systems and the evolution of quantum computing.
Explanation:Why Do Computers Use Binary Instead of Decimal?Computers use binary instead of decimal because they rely on the electronic states which represent two possible states: on and off. Binary is a system that is represented with two unique digits (0 and 1), corresponding to these off and on states respectively. This simplicity allows computers to perform operations reliably and efficiently. Processing binary data is also more straightforward due to the nature of digital circuits, which handle two distinct states more easily than multiple states required by a decimal system. For instance, in ASCII encoding, the letter A is represented as the number 65, which in binary is 1,000,001.
Additionally, binary allows for simpler and more reliable storage and processing of data. Binary representation of numbers, like the decimal number 1837 being 11100101101 in binary, is managed internally by using sequences of binary digits to encode information. Computers can represent very large numbers, such as with AES-128 and AES-256 encryption keys, where the number of possible keys is 2128 and 2256 respectively. This demonstrates not only the vast representational scope but also the security that binary encoding can provide due to the computational difficulty of attempting every possible key combination.
The binary system is fundamentally suited to digital technologies and replicates the digital nature of biological systems, such as DNA encoding with A, C, G, and T. It also contributes to clearer data transmission for cell phone conversations and television signals. Moreover, the advent of quantum computing further emphasizes the benefits of binary systems, as qubits which behave based on quantum mechanical phenomena still rely on digital manipulation of data.
Variables that are shared by every instantiation of a class are ___________.
Variables that are shared by every instantiation of a class are class variables. Class variables are those that contain static modifiers in their declaration.
What are class variables?They are also known as static variables. In the definitions of functions, a class or variable parameter serves as a model for a family of classes or variables. It is an important part of object-oriented programming (OOP).
When used as an input, such as when passing a value to a function, and when used as an output, such as when obtaining a value from the same function. They can, for example, serve as a model for a function.
Therefore, the Class variables are those that are shared by all instances of a class. Static modifiers appear in the declaration of class variables.

Emilio has created a document in Word and needs to print labels. He is shopping at a store and finds Avery labels and another brand that is less expensive. What does Emilio need to do before buying the less expensive labels?
Emilio should check the less expensive labels for Word compatibility, ensure they fit his printing and application needs, and confirm that he can create or find a suitable template before purchasing.
Explanation:Before Emilio purchases the less expensive labels, he needs to ensure that they are compatible with the Word document he created for printing labels. First, he should check the packaging of the labels to see if they provide a template or mention compatibility with Word. Many label manufacturers offer templates that can be downloaded and used within Word. If no information is provided, Emilio should look for the label size and compare it to the available templates in Word, or consider measuring the label dimensions and configuring a custom template if necessary.
Furthermore, Emilio should make sure that his printer can handle the label material and that the label adhesive is suitable for the surface to which they will be applied. If the less expensive labels provide all the necessary details for creating a Word template and are suitable for his printing and application needs, he can opt for the more affordable option without compromising his project.

The part of the poppet valve that contacts the valve seat is called the A. face. B. margin. C. head. D. stem.
Answer:
A. Face
Explanation:
A poppet valve some time called mash room valve.The word poppet shares etymology with "puppet". In past "puppet valve" was synonym for poppet valve. however, this usage of "puppet" is now obsolete. The valve stem moves up and down inside the passage called guide, which is fitted in the engine-block. the head of the valve called valve face, is generally ground to a 45 degree angle. So as to fit properly on the valve seat in the block and prevent leakage.
