011110 is the following base 10 & base 2 numbers in signed magnitude, one’s complement and two’s complement.

c)011110

<u>Explanation:</u>

Converting 10 base signed number as two complements. In computer signed is maintain in registered.

But computer needs all values in bits. In hardware it is considered as on or off methods. ASCII values are converted into bits and executed by CPU.

All values which been entered in computer are taken respective ASCII values and converted to bits. Normally sign symbol are maintained as registered flag which can be know if end user knows assembly programming languages.

Assembly language by which direct interacted with machine languages and faster in executions.

Suppose you draw two cards from a standard deck of 52 playing cards. What is the probability that they are both sixes? Keep at l
GaryK [48]

Answer:

0.00452

Explanation:

There are 4 sixes in a deck. So the chance that the first card you draw is a six, is 4/52. Then there are only 3 sixes left and 51 cards. So the chance that the second one is also a six is 3/51.

The combined chance is the multiplication, i.e., 4/52 * 3/51 = 0.00452

What is the difference between C and C++ programming Language?
Elena L [17]

Answer:

 The main difference between the c and the C++ programming language are as follows:

  • The C language is the type of procedure programming language and on the other hand, C++ is the combination of object oriented (OOPS) and the procedure programming language.
  • The C programming language does not support any type of object and class in the system. While the C++ programming language is also known as hybrid programming language.
  • The C programming language does not support any type of operator overloading and function. On the other hand, the C++ programming language supported both the function overloading and the function.

Describe the three-schema architecture. Why do we need mappings among schema levels? How do different schema definition language
VARVARA [1.3K]

Answer:

Three Scheme architecture contains internal level, conceptual level, and external level.

In the internal level physical structure of the database described. The internal Schema is also known as physical Schema, as it is used to define the data that stored in a block. Internal Schema describes a sophisticated level of data structure in detail.

The conceptual level design of the database has described, and it is known as a logical level. The conceptual level describes the whole structure of the database. It describes the relationships among the data. Implementation of data are hidden in a theoretical level

On the external level, databases contain schemas that represent a different view of the database. Each describes the database that the user interested in and hides the remaining database. The external database is also known as view schema.

Explanation:

The mappings between schema levels happen due to visualization and schema matching. DBMS has three schema level.

In the attached diagram

It shows the DBMS architecture.

Mapping is a way to transfer and respond to the request between the various database architecture.

Mapping takes more time to transfer data in small DBMS.

External / Conceptual mapping transforms the data from the outer level to the conceptual schema.

In Conceptual / Internal mapping, response transforms from conceptual to internal level.

Document Schema Definition Language (DSDL) is a framework in which multiple validations can be applied to achieve a complete validation result. In this way, schema definition language support this architecture.

vladimir2022 [97]

The notation used to represent MAC address is hexadecimal number.

Media access control address (MAC address) is a unique address assigned to a network interface controller (NIC) or network adapter. MAC addresses are also known as hardware addresses or physical addresses.

MAC addresses are 12-digit hexadecimal numbers (48 bits or 6 byte in length). MAC address allow computers to uniquely identify themselves.

Therefore hexadecimal numbers are used to represent MAC address.
