To combat piracy, many software publishers require users to type in a validation code, a sequence of numbers and letters in order to complete an installation. It is referred to as Card Validation Code (CVC). This series of numbers provides an additional layer of security to prevent fraud.

If you're unsure of what chart to use for a set of data, what feature does Excel include that will help you to decide?
LiRa [457]
Hmm Excel to this date does not help you decide what chart to use for your set of data. There is however a panel to which you can choose what type of data chart you would want... 


Though previous versions of Excel, A feature called 'Chart Wizards' goes through a set of instructions to which guide the user to pick what chart they should use.

Hope that helps ^^

Many languages distinguish between uppercase and lowercase letters in user-defined names. What are the pros and cons of this des
Korvikt [17]

Answer:

Explanation:

The reasons why a language would distinguish between uppercase and lowercase in its identifiers are:

(1) So that variable identifiers may look different than identifiers that are names for constants, such as the convention of using uppercase for constant names and using lowercase for variable names in C.

(2) So that the catenated words such as names can have their first letter distinguished, as in Total Words. The primary reason why a language would not distinguish between uppercase and lowercase in identifiers is it makes programs less readable, because words that look very similar are actually completely different, such as SUM and Sum.

Unless you share the backup HD only the local user is going to see it. Given that it's a server, it's not a problem. You can also hide the backup with attributes +h +s and many other ways.

Computer system with a 32-bit logical address and 4k-byte page size. assume that each entry of a page table consists of 4bytes.
Annette [7]

The number of bits in the physical address is 26 bits. The number of entries in a page table is \mathbf{2^{20}} entries. The size of the page table in a one-level paging scheme is 4MB.

<h3>
What is paging in Operating System?</h3>

Paging is a storage method used in operating systems to recover activities as pages from secondary storage and place them in primary memory. The basic purpose of pagination is to separate each procedure into pages.

We are given the following parameters:

  • 32-bit logical address
  • Page size = 4 KB = \mathbf{2^{12} \ bytes }
  • Size of each Page table entry = 4 bytes

Suppose the system supports physical memory size = 64 MB = \mathbf{2^{26} \ bytes}

Thus, the number of bits in the physical address is computed as:

= \mathbf{log_2 \{Physical-memory-size\}}

=\mathbf{log_2(2^{26})}}

= 26 bits

The number of entries in a page table = logical address space size/page size

The number of entries in a page table \mathbf{= \dfrac{2^{32}}{2^{12}}}

\mathbf{=2^{20}} entries

In a one-level paging scheme, the size of the table is:

= entire no. of page entries × page table size

= \mathbf{2^{20}\times 4 \ bytes}

= 4 MB

b.

suppose that this system supports up to 2^30 bytes of physical memory.

  • The size of the page table will be the same as 4 MB due to the fact that the number of entries, as well as, the page table entry size is the same.

Since the size of the page table surpasses that of a single page. A page cannot include a whole page table. Therefore, the page table must be broken into parts to fit onto numerous pages, and an additional level of the page table is required to access this page table.

  • This is called the Multi-Level Paging system.

Therefore, we can conclude that the number of bits in the physical address is 26 bits, the number of entries in a page table is \mathbf{2^{20}} entries, and the size of the page table in a one-level paging scheme is 4MB.
