What are the arguments for and against representing boolean values as single bits of memory?

For: Using a single bit instead of an entire byte will conserve memory
Against: Processors to have addresses for single bits. So up to 8 Booleans values can be combined into a single byte, which means bit-wise arithmetic to separate the separate values. Although this conserves memory, it takes more time (CPU time) to deal with.

∙ 14y agoAs single bits you could store 8 boolean values per byte, however you would have to use a logical mask to read them.
There are circumstances where this is preferable and the proccess is referred to as a flag register.

Why is Boolean logic important in computer science?
Boolean logic can be thought of as "0 and 1" logic, or "True or False" logic. Boolean math started out as "True or False" expressions. In computers, the bits stored in memory are interpreted as either a '0' or a '1' (binary numbers). Computer scientists (usually, though you can prove out the concept either way) map '0' = FALSE and '1' = 'TRUE', and thus the operations and decisions made in a computer can be expressed/evaluated as Boolean logic/math expressions.
The int data type requires more memory than the double data type?
No, the int variable uses less memory, and therefore it is preferable to use an int rather than a double where you can.A boolean variable uses even less memory, but obviously is useful only in limited circumstances.
What primitive data types can normally be represented and processed by a CPU?
The primitive data types that can normally be represented and processed by a CPU are an integer, real number, character, Boolean, and memory address

What are the two basic ways in representing linear structures in memory?
Data structures are classified as either linear or non linear, a data structure is said to be linear if its elements form a sequence, or, in other words, a linear list, there are two basic ways of representing such linear structures in memory, one way is to have the linear relationship between the elements represented by means of sequential memory locations, these linear structures are called arrays, the other way is to have the linear relationship between the elements represented by means of pointers or links, these linear structures are called linked lists.
How many characters can be taken as command line arguments?
Platform dependent. Many in unix, few in WinDos.
What is system bank schema?
A bank schema system has columns and rows representing the system memory sockets. Independent sockets are shown in rows and banks of sockets are shown in columns. It is a way to diagram memory configurations.
