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...
