The more programs you download to your PC, the longer the system starts to boot. In addition to brakes, various failures can also occur. Along with the software installation, we load and autoload. The list can become so long that the computer will turn on forever. To prevent this from happening, you will have to figure out how to remove applications from startup

When one of the existing operating systems (old or new) becomes unnecessary, many begin to wonder how to remove unnecessary operating systems from a computer without damaging the one that they want to keep working. Simply deleting files and directories in one of the partitions, alas, does not lead to anything good, and often can even provoke situations when the required system stops loading at all

In all Windows systems, without exception, it is quite common to encounter an error when starting the application 0xc0000142. Not all ordinary users know how to fix this problem. Below are some simple and kind of universal methods that will get rid of this failure in a matter of minutes. But first, let's dwell on the reasons that can theoretically cause the appearance of such an unpleasant situation

Solid State Drives (SSDs) have become a great alternative to traditional hard disk drives (HDDs) over the past few years as they provide much faster performance. Considered by many IT pros to be a benchmark in performance, they recommend it to anyone who wants to take their PC to the next level

After assembling the computer, it needs to be checked for the stability of the components. The latter is measured by various stress tests organized by special programs. They help to check all elements of the PC, including the processor, for resistance to loads

Perhaps, in some future, computing will forget about zeros and ones, and processors will operate not by bytes and words, but so far everything is represented by the binary world and lives by its rules. What is a stack and where it is applied, - most likely, it will become absolutely not clear. Even at the beginning of its appearance, the first processor had registers, and the logic of its work needed memory. As a result of the implementation of simple ideas, the “what is it” stack has become de facto “it should be”

At the beginning of the 19th century, Jakob Steiner, a geometer from Berlin, set the task of connecting three villages in such a way that their length was the shortest. Subsequently, he generalized this problem: it is required to find such a point on the plane that the distance from it to n other points is the least

Programming is a mirror of intelligence, and system programming is the optimal combination of the capabilities of a machine and the human mind. Application programming has always been about a specific task in a specific application area. System programming has always been significantly distinguished by the freedom to choose the logic of the algorithm. There was prestige and responsibility, but only in recent years have they received an objective content

A class in Java can be understood as a prototype that sets up variables and methods that are common to a certain type of instance. A class defines anything that characterizes and can create one or more types

The architecture of a microprocessor chip is a description of the physical layout of various elements. It directly affects how information and electrical current flow through the chip. A microprocessor can have either a CISC architecture - a computer with a complex set of instructions, or a simpler RISC

JavaScript is an interpreted programming language, a dialect of the ECMAScript standard. It is a variation between Java and HTML. Defined as an object-oriented, prototype-based, imperative, loosely typed, and dynamic language

Linux is a unique family of operating systems for reliable and secure operation. The idea, each member of the family is different in varying degrees, but the main idea of "working reliably, safely and stably" is impeccably observed. Installation and maintenance of Linux systems is available even to a beginner, but the acquired potential of knowledge, skills and experience makes the work of a system administrator much more efficient, and the work of the server is perfect

Programming languages are used by developers to write specific sets of instructions to microprocessors that perform specific tasks. There are many kinds of languages. The engine, created by computerization pioneer Charles Babbage, was the forerunner of modern personal computers, or rather PC logic. In order for the developer to correctly select instructions for writing a program, it will be necessary to perform a competent comparison of programming languages. This article is about it

The VLAN feature is not often found in ISP equipment, however many solutions on the market configure networks to this standard through software, which brings great benefits in terms of security and efficient equipment management

The web resource is located on the server and organizes the exchange of information. The logic and tools of this exchange are essential. Displaying the site page in the visitor's browser is the transfer of information, a link to a file is transferring it to the visitor, the upload form is transferring the file to the server. The implementation of these simple tasks in modern conditions requires a reasonable combination of logic and tools

The installation file contains the program and can be executed or run on a computer. On the Windows operating system, they usually have a .bat, .com, or .exe extension. Users who receive an .exe file as an email attachment must be sure that the file comes from a trusted source and is not a computer virus

Design patterns are very popular among software developers because they represent a well-described solution to a typical problem. These are assistants that automate complex repetitive tasks and allow team members with different skill levels to complete them

The SMART end to end error is part of the hard drive test technology at risk of failure. Statistically, SMART can predict more than half of disk failures, making this technology a reliable source of information about the current state, preventing device failure

Asynchronous programming allows you to achieve greater efficiency in software because it does not block the execution flow of long processes or user interactions. Many novice programmers find this process difficult to understand at first, especially if they are used to thinking imperatively and sequentially

From our article you will learn how to make a newsletter in Viber yourself and what to pay special attention to so that there are no unnecessary problems. We will analyze the advantages and disadvantages of each method, as well as the feasibility of their application. So let's get started

Linear programming (LP) - mathematical and static sections that allow researchers to establish optimal solutions. LP problems are different in that they are bounded and linear. The characteristics of the LP make it an extremely useful feature in many applications

And in the latter, new features appear, such as turning off the computer on a schedule. And we will talk about this in the article, find out what programs can help with this and why it is

Android mobile system users regularly connect their devices to computers. To do this, they use USB connections, which allows you to move some files from your smartphone to your computer or vice versa. Sometimes, for some reason, the connection fails. In the article we will find out why the computer does not see the phone via USB

Blue screen at startup of Windows operating systems is a fairly common phenomenon. Now we will talk about BSoD error 0x0000000A and the like. As a rule, they all arise for similar reasons and are eliminated by similar methods. The following methods may apply depending on the situation

Peers are called client machines involved in the process of downloading and distributing files when downloading from torrent trackers. Connection to peers is a method of connecting, as it were, to a mirror server, which at the moment is a user terminal on which some information is located. But sometimes the number of dispensers may decrease (for example, when the user uploaded the data and stopped the distribution)

If you decide to build a website, you won't get far without html. Of course, there is also CSS, PHP and other scripting languages, without which a full-fledged website, as you are used to seeing it, will not work. However, it is the basic html tags that will allow you to lay the foundation for your site

Programming languages, their structure, types and systematics. Review of various classifications. Systematization of programming languages by abstraction level, execution model, typing and generation. Application areas of different types of languages

In php, merging arrays is possible in several ways. Three functions are available for this: array_merge(), array_merge_recursive(), implode(). The first function and the second result in a new array, the last concatenates the elements into a string

Encryption is designed to hide information from outsiders. There are two types: synchronous and asynchronous. In synchronous, the same key is used for encryption and decryption. Asynchronous uses two different keys

There are three ways to remove spaces in strings. The trim() function removes extra characters on the sides of a string: spaces, tabs, line breaks. The preg_replace() function removes characters anywhere in a string using regular expressions. str_replace() is a simplified version of preg_replace()

To create a database in SQL DBMS, the CREATE statement is used. Details are specified in the arguments, some of which are only available for use in recent versions of the language. Database names must be unique, they can only contain allowed characters

Decorators in Python are a powerful tool for modifying existing classes and functions. They are needed when you need to add some methods to a function. In order not to create a new one, the current one is wrapped with a decorator
