Binary is the simplest kind of number system that uses only two digits of 0 and 1 (i.e. value of base 2). Since digital electronics have only these two states (either 0 or 1), so binary number is most preferred in modern computer engineer, networking and communication specialists, and other professionals.Whereas Hexadecimal number is one of the number systems which has value is 16 and it has only 16 symbols − 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and A, B, C, D, E, F. Where A, B, C, D, E and F are single bit representations ... Read More
In this section, we will see different addressing modes of the 8051 microcontrollers. In 8051 there are 1-byte, 2-byte instructions and very few 3-byte instructions are present. The opcodes are 8-bit long. As the opcodes are 8-bit data, there are 256 possibilities. Among 256, 255 opcodes are implemented.The clock frequency is12MHz, so 64 instruction types are executed in just 1 µs, and rest are just 2 µs. The Multiplication and Division operations take 4 µsto to execute.In 8051 There are six types of addressing modes. Immediate AddressingModeRegister AddressingModeDirect AddressingModeRegister IndirectAddressing ModeIndexed AddressingModeImplied AddressingModeImmediate addressing modeIn this Immediate Addressing Mode, the data ...

Both BFS and DFS are types of graph traversal algorithms, but they are different from each other. BFS or Breadth First Search starts from the top node in the graph and travels down until it reaches the root node. On the other hand, DFS or Depth First Search starts from the top node and follows a path to reaches the end node of the path. Read this article to learn more about these two graph traversal algorithms and how they are different from each other. What is BFS? Breadth First Search (BFS) algorithm traverses a graph in a breadth-ward motion ... Read More
Following are the differences between OSI and TCP/IP Reference Model −OSITCP/IPOSI represents Open System Interconnection.TCP/IP model represents the Transmission Control Protocol / Internet Protocol.OSI is a generic, protocol independent standard. It is acting as an interaction gateway between the network and the final-user.TCP/IP model depends on standard protocols about which the computer network has created. It is a connection protocol that assigns the network of hosts over the internet.The OSI model was developed first, and then protocols were created to fit the network architecture’s needs.The protocols were created first and then built the TCP/IP model.It provides quality services.It does not ...

Have you ever wondered how you can add quotes to the text or words in Excel? Adding quotes is similar to adding symbols as prefix and suffix to the words. It can be done using the "format" function in Excel. In this tutorial, we have provided a detailed step-by-step explanation of how you can add quotes around numbers or text in Excel. Adding Quotes around Text using "Format Cells" Option You can use the "Format Cells" option in Excel to add quotes around numbers or text. It is simple process. Step 1: Let us suppose we have an Excel sheet ... Read More
To hold an image in MySQL database generally blob type is used. Therefore, make sure that you have a table created with a blob datatype with the following description:+-------+--------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------+--------------+------+-----+---------+-------+ | Name | varchar(255) | YES | | NULL | | | image | blob | YES | | NULL | | +-------+--------------+------+-----+---------+-------+To insert an image in to MySQL database, follow the steps given below:Step 1: Connect to the databaseYou can connect to a database using the getConnection() method of the DriverManager class.Connect to the MySQL database ...

To pop the first element in the list, use the RemoveAt() method. It eliminates the element from the position you want to remove the element.Set the listList myList = new List() { "Operating System", "Computer Networks", "Compiler Design" };Now pop the first element using RemoveAt(0)myList.RemoveAt(0);Let us see the complete example.Example Live Demousing System; using System.Collections.Generic; using System.Linq; class Program { static void Main() { List myList = new List() { "Operating System", "Computer Networks", "Compiler Design" }; ...

Handshaking is an I/O control approach to synchronize I/O devices with the microprocessor. As several I/O devices accept or release data at a much lower cost than the microprocessor, this technique is used to control the microprocessor to operate with an I/O device at the I/O devices data transfer rate.The drawback of the strobe approach is that the source unit that starts the transfer has no method of knowing whether the destination unit has received the data element that was located in the bus. A destination unit that initiates the transfer has no method of knowing whether the source unit ... Read More
A tensor in PyTorch can be normalized using the normalize() function provided in the torch.nn.functional module. This is a non-linear activation function.It performs Lp normalization of a given tensor over a specified dimension.It returns a tensor of normalized value of the elements of original tensor.A 1D tensor can be normalized over dimension 0, whereas a 2D tensor can be normalized over both dimensions 0 and 1, i.e., column-wise or row-wise.An n-dimensional tensor can be normalized over dimensions (0, 1, 2, ..., n-1).Syntaxtorch.nn.functional.normalize(input, p=2.0, dim = 1)ParametersInput – Input tensorp – Power (exponent) value in norm formulationdim – Dimension over which ...
