Platform Devices and Drivers Before understanding platform devices and drivers, let’s understand the need which resulted in the introduction of the concept of platform devices and drivers. Linux Kernel introduced the concept of Linux Device model in kernel 2.6 release. According to Linux Device model, all the devices in the …
RISC AND CISC In broader terms, computers can be divided into two components- hardware and software. For architecture designing , both components play a major role. So, the architecture designing of CPU depends on two computing designs:- CISC(Complex Instruction Set Computer) and RISC(Reduced Instruction Set Computer). Before discussing CISC and …

In this chapter we will be discussing about different ways of allocating memory in c language. C provide us the flexibility to allocate memory dynamically at run time in case we are not sure of size of memory required at the time of compilation of program. C provides various functions …
There might be scenario when we know that that member of structure will take very short range of values and for storing that values we don’t need full memory allocated for that variable. example:- struct test { int male_allowed; int female_allowed; }; in the above structure we have two member male_allowed and female_allowed. …
