Three questions Plz answer for me?

Question

Explain what a bitmap is?
What is ASCII code?
What can a byte represent?

Answer 1

The method of storing information that maps an image pixel, bit by bit. There are many bitmapped file formats, .bmp, .pcx, .pict, .pict-2, tiff, .tif, .gif (89a), and so on. Most image files are bit mapped. This type of file gives you the ´jaggies´, when examined closely you can see the line of pixels that create edges. Bitmap images are used by all computers. The desktop or screen information for all Windows machines uses .bmp files, while the Macintosh uses pict files.

American Standard Code for Information Interchange. Pronounced AS-key. It's the most popular method used by small computers for converting letters, numbers, punctuation and control codes into digital form. Once defined, ASCII characters can be recognized and understood by other computers and by communication devices. ASCII represents characters, numbers, punctuation marks or signals in seven binary bits. A capital "C", for example, is 1000011, while a "3" is 0110011.


A group of data bits that are processed together. Typically, a byte consists of 8 bits. A byte is a series of 8 bits. Also called a character like A-z 1-9 etc..There are kilobytes, Megabytes, Gigabytes, Terabytes, etc. 1 Byte = 8 bits 1 kilobyte = about 1,000 bytes 1 Megabyte = about 1,000,000 bytes 1 Gigabyte = 1,000,000,000 bytes 1 Terabyte = 1,000,000,000,000 bytes

Answer 2

Bitmap is in the word ...a map of bits...which are pixels of different colours that make up the image.
ASCII code is code of 0's and 1's such as 00110011 ...which wud represent a letter/number/symbol on ur keyboard. It's how your computer recognizes what they are. (American Standard Code for Information Interchange)
A byte is 8 bits ...so 8 bits of data ...8 letters maybe
