Illustrator requires specialist knowledge to be competent, and the learning curve is very steep. Illustrator also can output fairly large file sizes, with the length of the illustrator file not necessarily corresponding to the size of the image. Illustrator itself can be very expensive, £65 for a new copy, or £15 a month for a creative cloud subscription from adobe.

There are many limitations such as there is a significant amount of knowledge required to successfully use the program. Meaning that either research before hand will have to be done before proper use or learning will have to be done over time with use of the product. Lemon As well as this limitation, It takes up a rather large size of RAM and HDD meaning less storage space for other programs, and a reduced ability to multi task smoothly. Adobe photo shop is costly meaning that a small investment of around £50 for a straight up payment or £8.57 a month to acquire the legal file, so those with financial difficulties may struggle to purchase this product. They no longer sell disk copy's of the latest adobe versions therefore an internet connection is required to download an up to date version that offers more features and perhaps bug fixes.

limitations

The spinning of the platters can sometimes result in vibration

HDD doesn’t produce much heat, but it will have a measurable amount more heat than an SSD due to moving parts and higher power draw

Slower than SSD

Magnets can erase data

Can’t be accessed from anywhere outside of your local network
benefits
Only around $0.06 per gigabyte, very cheap (buying a 4TB model)

have bigger write cycles than most ssds

# data[].attributes.body
Benefits:

SSD can handle drops and shacks better than a HDD this is because they do not have any mechanical moving parts that can be easily disturber and damaged.

SSDs produce less heat than a conventional HDD this is because they do not have mechanical moving parts such as Motors that produce lot's of heat. They only have a PCB board that contains lot's of flash memory and a driver this setup produces next to no heat under normal stress conditions.

SSDs have less malfunctions this is because they do not have moving parts that are more likely to wear down and cause problems.

SSDs can support higher read and write speeds than HDDs this is because they memory can run at can run at higher speeds (flash Memory).

Limitations:

SSDs have a limited amount of write cycle this number will be different depending on each SSD but what ever the number the write cycles are considerable less than a conventional HDD.

SSDs do not give a warning to when they will stop working, they will stop working intently and not work again. The way it to predict its life time and replace it before it go dead.

They are more costly than the standard HDD this is becasue the memory costs more (flash memory).

CRT: Advantages:

1. Resolution and Aspect Ratio
the image never needs re-sizing

2. Highest Resolutions
CRTs run at the highest pixel resolutions generally available.

3. Black-Level and Contrast
Produce a very dark black and the highest contrast levels normally available. Suitable for use even in dimly lit or dark environments.

4. Color and Gray-Scale Accuracy
CRTs produce the very best color and gray-scale. They have a perfectly smooth gray-scale with an infinite number of intensity levels whereas other screens can only do so approximately.

5. Motion Artifacts
CRTs have fast response times and no motion artifacts. Best for rapidly moving or changing images. like sonic 2 on the Sega genisys.

Disadvantages:

1. Sharpness
They are not as sharp as an LCD at its native resolution. Imperfect focus and color registration also reduce sharpness.

2. Interference
All color CRTs produce annoying Moiré patterns. Many monitors include Moiré reduction, which normally doesn't eliminate the Moiré interference patterns entirely.

3. Geometric Distortion
Subject to geometric distortion and screen regulation problems. Also affected by magnetic fields from other equipment including other CRTs.

4. Brightness
Relatively bright but not as bright as LCDs. Not suitable for very brightly lit environments.

5. Screen Shape
Some CRTs have a rounded spherical or cylindrical shape screen. Newer CRTs are flat.

6. Emissions
CRTs give off electric, magnetic and electromagnetic fields. There is considerable controversy as to whether any of these pose a health hazard, particularly magnetic fields. The most authoritative scientific studies conclude that they are not harmful but some people remain unconvinced.

7. Physical
They are large, heavy, and bulky. They consume a lot of electricity and produce a lot of heat.

LCD's: Advantages

1. Sharpness
Image is perfectly sharp at the native resolution of the panel. LCDs using an analog input require careful adjustment of pixel tracking/phase..

2. Geometric Distortion
Zero geometric distortion at the native resolution of the panel.

3. Brightness
High peak intensity produces very bright images. Best for brightly lit environments.

4. Screen Shape
Screens are perfectly flat.

5. Physical
Thin, with a small footprint. Consume little electricity and produce little heat.

Disadvantages:

1. Resolution
Re-scaling results in significant image degradation, particularly for fine text and graphics.

2. Interference
Automatic pixel tracking/phase controls seldom produce the optimum setting.

3. Viewing Angle
Limited viewing angle. Brightness, contrast, gamma and color mixtures vary with the viewing angle.

4. Black-Level, Contrast and Color Saturation
LCD's have difficulty producing black and very dark grays. As a result they generally have lower contrast than CRTs.

5. White Saturation
The bright-end of the LCD intensity scale is easily overloaded, which leads to saturation and compression. When this happens the maximum brightness occurs before reaching the peak of the gray-scale or the brightness increases slowly near the maximum.

6. Color and Gray-Scale Accuracy
The internal Gamma and gray-scale of an LCD is very irregular. Special circuitry attempts to fix it, often with only limited success. LCDs typically produce fewer than 256 discrete intensity levels.

7. Bad Pixels and Screen Uniformity
LCDs can have many weak or stuck pixels, which are permanently on or off. Some pixels may be improperly connected to adjoining pixels, rows or columns. Also, the panel may not be uniformly illuminated by the backlight resulting in uneven intensity and shading over the screen.

8. Motion Artifacts
Slow response times and scan rate conversion result in severe motion artifacts and image degradation for moving or rapidly changing images.

9. Aspect Ratio
LCDs have a fixed resolution and aspect ratio. For panels with a resolution of 1280x1024 the aspect ratio is 5:4=1.25, which is noticeably smaller than the 4:3=1.33 aspect ratio for almost all other standard display modes. For some applications may require switching to a letterboxed 1280x960, which has a 4:3 aspect ratio.

10. Cost
Considerably more expensive than comparable CRTs.

Vector images are used in most aspects of graphic design and are the preferred format for printing, both on paper and on clothes. The reason for this is that while a bitmap image can look great on the screen, which usually has a resolution of about 72 pixels/dots per inch (DPI), it will normally have to be scaled by a factor of 8 or more when printed since modern printers routinely produce resolutions of 600 pixels/dots per inch. Vector images can handle this type of scaling without any problems while bitmap images struggle with it.

Bitmap images (also known as raster images) are made up of pixels in a grid. Pixels are picture elements; tiny dots of individual color that make up what you see on your screen. All these tiny dots of color come together to form the images you see. Most computer monitors display approximately 70 to 100 pixels per inch--the actual number depends on your monitor and screen settings.

where as vectors graphics are images that are completely described using mathematical definitions. The image below shows the principle. To the left you see the image itself and to the right you see the actual lines that make up the drawing.Each individual line is made up of either a vast collection of points with lines interconnecting all of them or just a few control points that are connected using so called Bézier curves. naan-bread It is this latter method that generates the best results and that is used by most drawing programs.

# data[].attributes.body
Lossless data compression is used in many applications. For example, it is used in the ZIP file format and in the GNU tool gzip. It is also often used as a component within lossy data compression technologies (e.g. lossless mid/side joint stereo preprocessing by the LAME MP3 encoder and other lossy audio encoders).

Is lossless compression reversible? Explain.

# data[].attributes.body
Yes lossless compression is reversible this is because it uses algorithms this can simplify parts of the file which can reduce the total file size because the information has been reduced to a more simple state.

Lossless compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data.  Lossless compression reduces a file's size with no loss of quality. This seemingly magical method of reducing file sizes can be applied to both image and audio files. While JPEGs and MP3s use lossy compression, newer compression algorithms, such as JPEG 2000 and Apple Lossless compression, can be used to create lossless compressed files. naan bread

Lossless compression basically rewrites the data of the original file in a more efficient way. However, because no quality is lost, the resulting files are typically much larger than image and audio files compressed with lossy compression. For example, a file compressed using lossy compression may be one tenth the size of the original, while lossless compression is unlikely to produce a file smaller than half of the original size.

you can reverse it but it will lose some data and become lower quality unlike lossy

# data[].attributes.body
For images: RAW, BMP, and PNG are all lossless image formats. JPEG and gif are lossy image formats.

For audio: WAV, FLAC, and ALAC are all lossless audio formats. MP3, MP4, and OGG are lossy audio formats.
