A virus is a program that can ‘infect’ other programs by modifying them to involve a possibly evolved copy of itself.
Viruses effect program files , but they can also effect certain types of data files that support executable content.
A virus may not be infectable, but can allow for a viral code. Vulnerabilities in certain products can allow data files to become manipulated in a way that it can cause the host program to be unstable.
Unsaturated fats are divided into monounsaturated fats and polyunsaturated fats. Both types are thought to have beneficial effects on cholesterol levels.
Monounsaturated fats help lower bad (LDL) cholesterol while also boosting good cholesterol (HDL).
Polyunsaturated fats are thought to help lower total and bad cholesterol, but monounsaturated fats are favored because some research says that polyunsaturated fats are less stable. They can also reduce levels of good cholesterol as well as bad.
Polyunsaturated fats are sometimes a good source of omega-3 fatty acids. They are found mostly in cold-water fish, nuts, oils, seeds, dark leafy greens, flaxseed oils and some vegetable oils.
A stroke is a sudden impairment in brain function.
If someone is having a stroke, they may not be able to talk, speak clearly, walk, or move a limb because blood has stopped flowing to an area of the brain. This is usually caused by the blockage of or rupture of a blood vessel.
Strokes leave behind long-lasting neurological impairments. The severity of these depends on the damage to the brain.
There are two major categories of stroke: ischemic and hemorrhagic. Ischemic strokes are caused by a physical blockage of blood flow to the brain. Hemorrhagic strokes are caused by a blood vessel inside of the brain rupturing.
Also referred to as Leonard of Pisa, Fibonacci was a number theorist.
He was born in approximately 1170 and died 1250.
He was born in Italy but he obtained his education in North Africa.
Fibonacci gave us our decimal number system which replaced the Roman Numeral sytem.
It was this problem that led Fibonacci to the introduction of the Fibonacci Numbers and the Fibonacci Sequence which is what he remains famous for today. The sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34, 55.. This sequence is that each number is the sum of the two proceeding numbers.
