Explain about the viruses in detail
Note 1: Viruses don't just infect computers, they may also affect mobile phones, MP3 players etc. - any device that can download files from a source such as internet is potentially at risk.
Note 2: Backing up may allow files which have become corrupted/lost (because of hacking or viruses) to be reinstated; though, this wouldn't recover the system nor would it prevent viruses/hacking affecting a system in the first place.
Note 3: Other problems like spam, pop ups, cookies, etc. are more of a nuisance (albeit they can considerably slow down operation of a computer system) and can be made inactive or blocked (as they can become active without user's knowledge) using appropriate software.

Evaluate personality defines? 1. System calls: Linux use a software interrupts to change into kernel mode whilst other UNIX system use an inter segment jump. 2. Message n
Define Programmed I/O. It is the result of input and output instructions written in the computer program. Every data item transfer is initiated by an instruction in the program
Define Polling. A Polling process is used to recognize the highest priority source by software means. In this process there is one common branch address for all interrupts.
Data hazards - computer architecture : A main effect of pipelining is to alter the relative timing of instructions by overlapping their execution. This introduces contro
Q. Illustration of cache size of a system? Cache Size: Cache memory is very costly as compared to main memory and therefore its size is generally kept very small. It has bee
Q. Explain about Hybrid model? Hybrid models are normally tailor-made models suiting to particular applications. In fact these fall in category of mixed models. These type of a
