Placental size: Most of the weight is due to the meaty chorionic plate and a minority due to the cord and the amniotic sac. On the basis of numbers alone, placentomegaly can be diagnosed when the weight is greater than 600 grams or the fetal:placental (F/P) weight ratio is 3:1 or lower.
Computer forensics analysis is not limited only to computer media. Computer forensics (sometimes known as computer forensic science) is a branch of digital forensic science pertaining to evidence found in computers and digital storage media.
A computer virus is a type of malicious software program (malware) that, when executed, replicates by reproducing itself (copying its own source code) or infecting other computer programs by modifying them. Infecting computer programs can include as well, data files, or the boot sector of the hard drive. When this replication succeeds, the affected areas are then said to be infected with a computer virus. The term virus is also commonly, but erroneously, used to refer to other types of malware.
