In this article, we'll show you how to make Windows 7 resume action from sleep mode based on a simple mouse action.
If you still use the Windows 7 operating system, you might wonder how to change the startup message. In this short article, we will explain how to have Windows 7 display a custom message at startup as a pop-up.
Overheating of the CPU caused by a temperature problem is definitely a bad sign, as it can destroy the processor and can cause instabilities in the hardware of the system. If you are experiencing a CPU that is overheating, this tutorial will introduce you to a few solutions.
Sometimes users will notice that their taskbar and desktop icons have gone missing. There are different methods of bringing back the desktop icons and taskbar on the computer screen. This article will guide you by showing 5 different methods to correct the problem.
Thanks to modern technology, computer programming (a.k.a. coding) has become accessible to everybody, not just the computer whizzes amongst us. In the following 'How To' guide, we'll introduce a selection of 5 apps that take different approaches teaching you to code using just your smartphone. Even though an app cannot replace professional courses, they will enable the user to obtain a basic skill level and understanding of coding thanks to their fun exercises.
Digital transmission is the sending of information over physical communication media in the form of digital signals. Analog signals must therefore be digitized first before being transmitted. The present article discusses in detail the different types of encoding.
Today, there are more than ever digital professions, which has made having a good Internet connection a necessity. Moreover, even people whose work is not strongly related to the Web, need it on an everyday basis to check their emails or participate in online courses. However, it is also well known that there are public wifi risks but in fact, this is not the only risk factor when it comes to security. This article discusses in detail the risks related to WIFI.
What is a client-server environment? Numerous applications run in a client-server architecture. This means that client computers (computers forming part of the network) contact a server that provides services to the client computers. These services are programs that provide data such as time, files, connection, etc.
What is and what does a motherboard do? The primary component of a computer is the motherboard (sometimes called the mainboard). The motherboard is the hub that is used to connect all of the computer's essential components. As its name suggests, the motherboard acts as a parent board, which takes the form of a large printed circuit with connectors for expansion cards, memory modules, the processor, etc.
The DB25 (originally DE-25) connector is an analog 25-pin plug of the D-Subminiature connector family (D-Sub or Sub-D). The DB25 connector is mainly used for serial connections, allowing for asynchronous data transmission as provided by standard RS-232 (RS-232C). It is also used for parallel port connections and was used to connect printers, that's why it's also known as a printer port (LPT). DB25 serial ports on computers have male connectors, while parallel port connectors are DB25 female.
Computer memory saves all data in digital form. There is no way to store characters directly. Each character has its digital code equivalent: ASCII code (for American Standard Code for Information Interchange). Basic ASCII code represented characters as 7 bits (for 128 possible characters, numbered from 0 to 127). In the 1960s, the ASCII code was adopted as the new standard. With it, characters can be coded using 8 bits for 256 possible characters.
In the late 1930s, Claude Shannon showed that by using switches that close for "true" and open for "false," it was possible to carry out logical operations by assigning the number 1 to "true" and 0 for "false." This information encoding system is called binary. It's the form of encoding that allows computers to run. Binary uses two states (represented by the digits 0 and 1) to encode information. This article discusses binary data encoding. You can find a binary decoder and encoder online.
In client/server systems, there are several types of configurations. This article will get into detail of the client server architecture and more precisely, 2-tier architecture and 3-tier architecture. We also explain the differences and the similarities of the two systems.
Some areas, even some rooms in your home, may not receive a good WiFi connection from your router. Continue reading to discover how to solve this issue by increasing the range of your WiFi.
A network card may have several types of connectors, with the most common being an RJ45 connector and a BNC connector (coaxial cable). In this article, we talk about the RJ45 ethernet crossover cable, as it is the most widely used.
What is WiMAX? WiMAX stands for Worldwide Interoperability for Microwave Access. It is a metropolitan wireless standard created by Intel and Alvarion in 2002 and ratified by the IEEE (Institute of Electrical and Electronics Engineers) under the name IEEE-802.16. More precisely, WiMAX is the commercial designation that the WiMAX Forum gives to devices that conform to the IEEE 802.16 standard to ensure a high level of interoperability among them.
The term memory applies to any electronic component capable of temporarily storing data. This article will explain the different categories of memory, the technical characteristics of memory, and the differences between Flash Memory, Read-Only Memory, and Random Access Memory.
In this article, you will learn what are different types of protocols and what are they used for.
