...screen is going to be and the higher quality the video will look. For UHD Tvs they support resolutions up to 4k resolution (3840x2160). The Highest Resolution out now is 4k resolution which is at 3840 x 2160 The image above shows you the different types of screen resolution used in different types of media devices. Ratios: Aspect ratio is the term given to describe the proportional relationship between its width and its height. Nowadays the standard ratio is 16:9 which will stretch to fit most if not every TV screen. The height is the first value and the second value is the width, for example 16:9 16 being the height and 9 being the width. This will determine how stretched an image will be on your screen, for example if you were to use 4:3 there would be a black border around the image, because it wouldn’t be stretched to fit the screen. For new 4k Monitors and TV the aspect ratio is 1.9:1 Compression: There are two different types of compression Lossy and Lossless. Compression is the term given when you take a file and make it smaller so that it takes up less space on your Hard Drive. Lossy compression is the type of compression method that when compressed and decompressed the file will lose the quality of the picture or video. Lossless compression is the type of compression that when compressed it can be decompressed without losing any of the quality. Lossy compression is the type of compression method that when compressed and decompressed the file will lose the quality...

...Task 1 The Control Unit There are two types of control unit which are hardwired and micro program where hardwired are for fixed architecture and are typically RISC and cost more than micro program because of the time required to design the circuits , but they are faster. Micro program control units are slower than hardwired but are easier and cheaper to implement as the instructions are stored in special control memory. The control unit controls all data going in, out and inside the CPU. The control unit decodes the data from ram and turns it into an instruction depending on what instruction set the control unit is programed or hardwired to have. Then if the instruction involves any logic or mathamatical caluculations it gets sent to the alu where it gets calculated and outpeted to the accumulator. The ALU The ALU is an acronym for arithmetic and logic unit, this is one of the most important parts of the CPU as it does all of the calculations. The ALU is a big array of different logic gates that are interconnected to preform basic logical and mathematical operation such as putting adding numbers or xoring two values. How the ALU is designed makes a big difference in terms of how powerful the processor will be as the more complicated...

...It can be quite annoying if the PC is often unresponsive, especially if there is something really important to be done or the user requires instant access to data for someone who is sitting in front of them. The following guidelines could be helpful to make computer faster. Lessen the Number of Applications Installed One of the main causes that slow down the PC is having too many applications installed in it, regardless of the system being used. When games and applications are installed to a computer, some files are stored in the Windows directory structure and a lot of changes happen in the Windows Registry file. Majority of these changes are not promptly obvious to the Windows user. Programs that are redundant repeatedly ask the system to run a maintenance and occupy the hard disk drive, causing Windows to become unacceptably slow to respond. The appropriate removal of these programs needs uninstalling the application by going to the Control Panel – Programs and Features icon. Uninstalling an application or a software instantly after using it can speed up pc. There are also available third party programs that could help to remove applications that don’t have uninstall procedures or don’t completely remove themselves. Stop All Unnecessary Background Processes At the left hand corner of the computer screen, there is a group of small icons called the “system tray” or “notification area.” Every icon corresponds to a program that has been initiated or is just running in the background...

...watching/listening to a file. There are many types of video formats being used in Multimedia, some of these would be MPEG, GIF and AVI. MPEGs would be used for Motion Graphics that have been compressed, it would be known globally as the best compatible lossy format. GIFs would be used in Motion Graphics as it is basically a mini video clip that is being played in a loop, this can be used graphically and creating a nice motion graphic. AVIs would be the best Motion Graphic option because it has a number of codec options, it would be mainly used as a media container. Screen Ratios Ratios is relating on the display that would be found on screens like a TV, monitor or cinema. There are many different types of ratios like 21:9, 16:9 and 4:3. The screen resolution for 16:9 is 1920x1080, which is know the most commonly used. But what a rations does is that if the video is a different ratio than 16:9, it will resize it so it can fit onto that size. When creating Motion Graphics you would have to make sure that it is the manageable size so that it will be able to be played on all or most types of screens. Resolution Screen resolution is all about the size of the screen or the video itself. When the Motion Graphic is set to a size like 840 x 400 it will come out in a lower quality. But if the graphic were to come out in a size like 1920 x 1080 it would be a higher quality. If the motion graphic was being displayed on a bigger screen, it will show each pixel bigger, this is because...
