4. The units of data measurement were introduced to manage and operate digital information. The basic or atomic unit of data measurement is a bit, which can store a value or no-value. The smallest amount of data that a computer system can access or address is a byte, and the byte consists of eight bits. The 32-bit computer systems operate in words; each word consists of four (4) bytes.

5. Virus: A computer virus attaches itself to a program or file allowing it to spread from one computer to another, infecting others as it travels. Worm: A worm takes advantage of file or information transport features on your system, which is what allows it to travel without human interaction. Trojan Horse: The Trojan Horse, at first glance will appear to be useful software but will actually do damage once installed or run on your computer. Those on the receiving end of a Trojan Horse are usually tricked into opening them because they appear to be receiving legitimate software or files from a legitimate source.

6. The Z1 originally created by Germany's Konrad Zuse in his parents living room in 1936 to 1938 is considered to be the first electrical binary programmable computer. Designed in 1979 by a Briton, William Moggridge, for Grid Systems Corporation, the Grid Compass was one fifth the weight of any model equivalent in performance and was used by NASA on the space shuttle program in the early 1980's.

8. Conclusion I think the future of computers will be smaller computers that work faster and have more memory than the ones we have. Computers will take over all other things such as T.V. The screen will be holographic like in the movies.
