Which one of these is the most commonly used hardware interface for attaching peripherals to a microcomputer?

1 answer:

Hey there!

The most commonly used hardware interface for attaching peripherals to a microcomputer is the universal series bus, or USB, port. Many computers have at least 2 to 4 USB ports that allow for multiple devices to be plugged in at once. In terms of wired devices as opposed to wireless, this is the main way that a mouse, a keyboard, a smartphone (for charging and syncing information), and many other devices are connected to computers.

Hope this helped you out! :-)

Answer:

Hope below explanations are enough.

Explanation:

1. JPEG (or JPG) - Joint Photographic Experts Group

JPEGs might be the most common file type you run across on the web, and more than likely the kind of image that is in your company's MS Word version of its letterhead. JPEGs are known for their "lossy" compression, meaning that the quality of the image decreases as the file size decreases.

You can use JPEGs for projects on the web, in Microsoft Office documents, or for projects that require printing at a high resolution. Paying attention to the resolution and file size with JPEGs is essential in order to produce a nice looking project.

2. PNG - Portable Network Graphics

PNGs are amazing for interactive documents such as web pages, but are not suitable for print. While PNGs are "lossless," meaning you can edit them and not lose quality, they are still low resolution.

The reason PNGs are used in most web projects is that you can save your image with more colors on a transparent background. This makes for a much sharper, web-quality image.

3. GIF - Graphics Interchange Format

GIFs are most common in their animated form, which are all the rage on Tumblr pages and in banner ads. It seems like every other day we have a new Grumpy Cat or Honey Boo Boo animated GIF. In their more basic form, GIFs are formed from up to 256 colors in the RGB colorspace. Due to the limited number of colors, the file size is drastically reduced.

This is a common file type for web projects where an image needs to load very quickly, as opposed to one that needs to retain a higher level of quality.

4. TIFF - Tagged Image File

A TIF is a large raster file that doesn't lose quality. This file type is known for using "lossless compression," meaning the original image data is maintained regardless of how often you might copy, re-save, or compress the original file.

Despite TIFF images' ability to recover their quality after manipulation, you should avoid using this file type on the web -- it can take forever to load. TIFF files are also commonly used when saving photographs for print.

5. PSD - Photoshop Document

PSDs are files that are created and saved in Adobe Photoshop, the most popular graphics editing software ever. This type of file contains "layers" that make modifying the image much easier to handle. This is also the program that generates the raster file types mentioned above.

The largest disadvantage to PSDs is that Photoshop works with raster images as opposed to vector images.

Assume the int variables i, lo, hi, and result have been declared and that lo and hi have been initialized. Write a for loop tha

IRISSAK [1]

Answer:

result=0;

for (i=lo ; i<=hi; i++){

result += i;

}

Explanation:

The question says result was declared but not initialized, so using result without initializing it to 0 would throw an error as result would be undefined and you can't add a number to undefined

Another way to do it to keep everything inside the loop would be

for (i=lo ; i<=hi; i++){

if (i==lo) result= 0;

result += i;

}

but this is impractical since it would add unnecesary operations in each cycle of the loop
