Indicate the values to be added as well as the column names: INSERT INTO table_name (column1, column2, column3, ...).

<h3>What is Database?</h3>

A database in computing is a structured collection of data that is electronically accessible and stored.

Large databases are housed on computer clusters or cloud storage, whilst small databases can be stored on a file system.

Data modeling, effective data representation and storage, query languages, security and privacy of sensitive data, and distributed computing challenges, such as providing concurrent access and fault tolerance, are all part of the design of databases.

In order to collect and process data, a database management system (DBMS) communicates with applications, end users, and the database itself.

The primary tools offered to manage the database are also included in the DBMS software. The combined database, database management system, and related applications are referred to as.

Hence, Indicate the values to be added as well as the column names: INSERT INTO table_name (column1, column2, column3, ...).

Write a code segment that displays the values of the integers x, y, and z on a single line, such that each value is right-justif
Elena L [17]

Answer:

x = int(input ("enter first number: "))

y = int(input ("enter second number: "))

z = int(input ("enter third number: "))

print('%6d %6d %6d' %(x,y,z))

Explanation:

Using python programming language we receive three integers variables (x,y,z) then using string formatting (%6) which specifies that the output should be right justified with a width of 6, the values are printed out.

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.
