126123## Variables And Data Types
127- In computer programming, a ** variable** is just like
128- a container to store digital data. A ** data type**
129- is the way you tell the computer how that data
130- will be interpreted. Should the computer interpret
131- that as letters? or numbers? or words? or simply
132- raw binary data? The computer does not know
133- that, you must tell it exactly.
134- 135- In computer programming, both these things
136- will enable you to store data and tell
137- the computer what kind of data it is. When you
138- store, you want to retrieve it later as per
139- needed. Remember also, computer's memory
140- is different from storage. Think of it
141- as the short-term memory and the storage
142- (the hard disk) as the long-term memory.
143- But during the runtime of a program you
144- are developing, you refer to memory as
145- ` storage ` . The computer's memory has the full
146- access to the CPU while the disk does not have
147- that access.
148- In order to read contents from the hard disk,
149- a request should be made. Hence, in programming
150- you are using the memory first not the disk.
151- There is the current development to combine
152- the two but is still on-going.
153- 154- Take note, the details of memory, hard disk
155- and CPU are quite complex but the mentioned
156- details above will serve as the starting point
157- for full comprehension.
