  For most people nowadays, using the internet involves accessing information or entertainment, viewing products and services, or using social media platforms to keep in touch with friends and acquaintances. It may seem that visiting a webpage merely involves entering the URL in the address bar, but that’s just the start of a more complicated process. In a split second the browser makes contact with globally distributed web servers, requests stored data packages, and then assembles the webpage from the information contained in the packages. Read on to find out how this process works and which steps are taken. 1.From URL to IP address The easiest way to access a website is to write the desired address into the address bar located in the browser. This address is known as a Uniform Resource Locator (URL), and every webpage can be reached with its own individual URL (web address). A URL is made up of several sections; all of which have their own functions. Here is a generic example of ...

  The document discusses the key components that make up a computer system unit. It describes 13 components: 1) ATX power supply, 2) central processing unit (CPU), 3) CPU fan, 4) CPU heat sink, 5) video card, 6) RAM, 7) modem, 8) sound card, 9) ribbon cable, 10) SATA cable, 11) motherboard, 12) DVD ROM drive, and 13) hard disk drive.   1.ATX power supply The most common computer power supplies are built to conform to the ATX form factor. ATX power supply also are designed to turn on and offf using a signal from the motherboard,and provide support for modern functions such as the standby mode availble in many computers. 2.Central Processing Unit(CPU) CPU is the portion of a computer system that carries out the instructions of computer program,and is the primary element carrying    out the computer's function.The CPU carries out each instruction of the program in sequunce'to perfor, the basic arithmatic, logical,and input/output operations of the system. 3.CPU fan Use ...

What is the Video representation   Video representation, as the name implies, specifies a way of representing a video. While some work refers to video representation as the way to present or express video content through some extracted or summarized content units such as scenes or objects, the majority regard it more as the way the video content is stored. In other words, it is about  video format  which describes the sequence, structure and content of frames that create the moving video image, along with any possible audio or text (closed caption) information. 1.Frame rate(FPS) Frames per Second (fps) :  The standard way to measure frame rate. Higher fps means more frames displayed each second. 24fps:  Often used in films for a cinematic look. 30fps:  Common for TV and online content with a natural motion effect. 60fps:  Ideal for high-definition video with smooth, lifelike movement 2.Colour Depth Color depth, also known as bit depth, is either the nu...

  Representing Numbers Negative number Representation Negative numbers are simply numbers that are less than zero. Computers use binary to represent and process numbers. For negative numbers, binary systems rely on specific encoding methods since binary naturally represents only non-negative values. Common representations include Decimal Representation In decimal (base-10) notation, negative numbers are represented with a minus sign. Examples: -8(a negative integer) -6.14 (a negative decimal number) -1/5 (a negative fraction) Sign-Magnitude Representation Sign-Magnitude Representation is a method used to represent signed numbers in binary form Example: A sign bit of  0  represents a positive number. A sign bit of  1  represents a negative number. Binary Representation  The binary number system is a base-2 numeral system that uses only two symbols: 0 and 1. Each digit in this system is referred to as a bit. Binary numbers are fundamental in computer science ...

Computer Specifications for IT experts When it comes to buying a new computer or upgrading your existing one, understanding ‌computer specifications can be a daunting task. With so many technical terms⁤ and acronyms, it’s easy to⁤ get lost​ in the jargon. ‌In this plain English guide, we will demystify⁣ the most important computer specs,‌ including RAM, ​CPU, GPU, and ⁢more. By the end of this article, you’ll have a clear understanding of what ⁤these specifications mean and how they impact your computer’s performance. 1. Processor (CPU) The processor is brain of the computer and it's needs to speed and   multi tasking ,while more cores improve handling of multiple tasks. The processors are small size chips made by silicon that are placed inside the devices to perform the task or operation within seconds and its speed is measured in terms of megahertz. The fetching, decoding, executing and write back the instructions are the four main primary functions of the processor Key Points...
