P1 - Describe the hardware and software used to create and edit graphic images Hardware and Software used in Graphics Work Hardware When producing graphics on a computer, specific hardware and software components are required.
All hardware used must be able to support the relevant software and be able to cope with the demands of the graphics editing. Having the correct hardware and software can improve the quality of the resulting graphics.
Graphics Card A graphics card is specialised card which is responsible for displaying instructions on the computer screen in a graphical format. The card receives instructions from the CPU and interprets them so that they can be displayed accurately.
The quality of the graphics produced depends on what type of graphics card is used — a card with better speed and storage capacity will produce graphics much faster and of a better quality.
Most graphics cards now come with a heat sink as the speed of the cards causes them to overheat quickly. The graphics card is connected to the monitor by using either a VGA visual graphics array or a DVI digital visual interface — a DVI cable offers better quality graphics than a VGA so it is often used when editing graphics.
Graphics cards impact graphical work as they are needed to display the content on the monitor and to process changes in graphics. Having a high speed graphics card will benefit graphical work as the computer can load graphics faster and respond to changes that the user makes almost immediately.
Modern graphics cards do not use up as much RAM as integrated on-board chipset graphics so allow the whole system to perform better — coincidently this allows applications like Photoshop to run more effectively.
In software packages e. Photoshop, this can make zooming in and changing the colour of each individual pixel much simpler. Without the graphics card no graphics can be displayed Some graphics cards cannot support high end graphics High end graphics cards require a good processor Internal Memory Internal memory is used to store programs and data on the computer.
There are two main types of memory used in digital graphics — random access memory and cache memory read-only memory is typically only used for storing programs permanently.
The access time for each application loaded into RAM will be the same hence the term random access. The rate at which a program loads will affect how quickly the program will be able to run, and if the RAM cannot load a program because it is full, the processor will load the program directly from ROM thus slowing the computer down.
More RAM can be added to a computer as there are typically 4 slots on the motherboard and only two are filled, alternatively the capacity of RAM can be increased to improve performance.
The contents stored within RAM will only be available from when it is loaded till the time at which he computer is powered down. How many gigabytes of RAM and how much there is in the computer will determine how much and how fast graphics can be loaded.
There are two places in which cache memory is located: Cache memory is used to address the difference in speed between the processor and RAM. Internal memory impacts graphical work as without it graphics cannot be loaded. A computer with more internal memory can perform more graphical functions and run more efficiently.
When dealing with large software packages such as Photoshop and Gimp, internal memory is used to run them.Unit Digital Graphics P1, M1 Essay examples Words | 15 Pages.
