Let us see how to determine the constant term in a binomial theorem with the help of an example. Example: Find the constant term in the binomial expansion of $(\frac{a^2 - 4}{a})^6$. Solution: First, we will expand the given binomial according to binomial expansion theorem as follows: $(\frac{a^2 - 4}{a})^6$ = $(-1)^{r 6}C_r$ $(\frac{4}{a})^r$ $(a^2)^{6 - r}$ = $(-1)^{r 6}C_r 4^r (a)^{12 - 3r}$

Malware-definition, history and classification. âMalwareâ is short for âmalicious softwareâ - computer programs designed to infiltrate and damage computers without the users consent.âMalwareâ is the general term covering all the different types of threats to your computer safety such as viruses, spyware, worms, trojans, rootkits and so on.omputer worms, on the other hand, spread without user action. Both viruses and worms can carry a so-called âpayloadâ â malicious code designed to do damage. Trojans and Rootkits â the masked threat. Trojans and rootkits are grouped together as they both seek to conceal attacks on computers.
