In hardware description languages like VHDL, a "parent" concurrent statement is used to establish a hierarchical design structure. It enables the creation and management of several processes within of a single organization. An illustration of a parent concurrent statement is as follows − entity my_entity is port ( clk: in std_logic; reset: in std_logic; data_in: in std_logic_vector(7 downto 0); data_out: out std_logic_vector(7 downto 0) ); end entity; architecture behavioral of my_entity is begin -- Parent Concurrent Statement parent_process: process(clk, reset) begin if reset = '1' then -- Reset condition data_out
The speak method in golang is obtained by the customized functions that you can define to achieve a specific functionality. Speak is a user-defined function that performs the task for which it is created. In this article, we are going to create an animal interface that defines the speak method. This interface serves as a blueprint for any type that wants to be considered an animal and provides a contract for implementing the Speak behavior. Here we are going to use three different methods: direct interface implementation, struct embedding as well as interface assertion along with examples to elaborate the ... Read More
Paged segmentation and segmented paging are two methods that operating systems use to manage computer memory allocation and address translation. Paged segmentation is a hybrid memory management scheme that combines segmentation and paging. Memory is divided into segments of different sizes, which are further divided into pages of fixed sizes. A segment table tracks segment location and size, while a page table tracks page location and corresponding physical addresses. When a program requests memory, the operating system allocates a segment of the required size and divides it into pages. Important aspects of paged segmentation Modern operating systems manage ...

In Go, channels are a capable highlight for concurrent programming, empowering communication and synchronization between goroutines. In this article, we are going to investigate how to form a channel of sort string in Go and utilize a goroutine to send messages to the channel at normal intervals of 2 seconds. We are going to give a step-by-step exhibit of the program, displaying the utilization of channels and goroutines. Syntax time.NewTicker(time.Second) The Syntax time.NewTicker(time.Second) is used to create a new Ticker value from the time package in Go. time.Sleep(duration) The Syntax time.Sleep(duration) is used to pause the execution of a ...

Overlay memory management technique allows multiple programs to be loaded into memory simultaneously, but only a portion of each program is resident in memory at any given time. This is used to increase the overall memory utilization and efficiency of the computer system. The technique swaps different parts of the programs in and out of memory as required. The overlay memory management technique is commonly used in situations where the memory requirements of the programs exceed the available physical memory. In such cases, the operating system can load the program into the memory in smaller sections, known as overlays. Each ... Read More
Pivot tables are a useful tool in Microsoft Excel that lets you easily analyse and summarise massive amounts of data. However, there may be times when you need to delete a pivot table from your worksheet, either to make room or to begin a new study. In this tutorial, we will show you how to delete a single pivot table or all pivot tables from your Excel spreadsheet. Whether you're new to Excel or an experienced user, this post will show you how to delete pivot tables in a basic and clear manner. By the end of this course, you ... Read More
A binary tree is a tree having at most two children whereas a binary search tree is the tree in which the elements in the left side of the tree are less than the elements in the right side of the tree. In this article, we will write Go language programs to check if a binary tree is a binary search tree. Here we will use different examples to provide a better understanding of the concept. Algorithm Step 1 − Create a Node struct with three fields the data of the node of type int, Left and right subtree ... Read More
A binary tree is a tree which has at most two children and height refers to the no. of levels in the tree. In this article, we will use two examples to find the height of a binary tree. In this Golang article we will write programs to print the height of a binary tree. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used to add values to an array slice. It takes number of arguments. The first argument is the array to which we wish to add the values followed by the values to add. ... Read More
Two of the most popular corporate Linux distributions on the market are Oracle Linux and Red Hat Enterprise Linux. Despite the fact that the two operating systems share the same source code, there are some significant variations between them that merit investigation. The similarities and differences between Oracle Linux and Red Hat Enterprise Linux will be highlighted when we compare the two operating systems in this post. What are Oracle Linux and Red Hat Enterprise Linux? A Linux distribution called Oracle Linux is based on the free and open-source CentOS operating system. It was created by Oracle Corporation and is ... Read More
Operating system hardening involves protecting an operating system to lower its attack surface and improve its overall security posture. In order to do this, the operating system settings must be configured. Updates and patches must also be installed, unused programs and services must be disabled, and security measures like firewalls, intrusion detection systems, and antivirus software must be put in place. Operating system hardening reduces the amount of potential attack pathways that hackers might take in an effort to decrease the probability that an attack would be successful. Operating system hardening is an ongoing process that requires regular review and ... Read More
