Q1.Explain how the optical disk storage facility operates?
Optical disk storage is an advancement of the floppy disk. The optical disk storage also called optical media is shinny and both recording surfaces are protected by two plastic plates which make it less exposed to dust and contamination. Unlike the floppy disks that store up to 1.44 of data, optical disks storages can store up to 650MB of data. They are 5.25 inches (12cm) and have a high storage density. Optical disks storage uses a high focused laser beam to read and write data stored on the disk. Because of this, more data can be compressed on the optical disk compared to a floppy disk about 400 more than times. Computers use compact disk read-only memory (CD-ROM) and write once, …show more content…
Explain the decimal system of measuring size of information and binary system used to measure memory size.
Binary system measures a kilobyte as 1,024bytes which is 10000000000 when converted into binary while the decimal system measures a kilobyte as 1,000bytes. However, the difference between the two systems is lesser. But it gets notable when you increase to megabytes and gigabytes. The binary value comes to 1,048,576byts and 1,073,741,824byts compared to 1,000,000byts and 1,000,000,000byts in the decimal system.
People use the decimal system which is in base 10 because it is the basis of the number system. 0,1,2,3,4,5,6,7,8,9 are the digits people calculate with. Unlike people, the computer uses the binary system which is in base 2. The smallest unit measurement on a computer is a Bit, short for binary digit. The computer uses what we call 1 and 0 with which it must do everything. In most cases when you type in something on your keyboard, it is in higher level and what the computer will do is accept and translate it to low level into 1 and 0.Example, A is equivalent to 65 and 01000001 in binary system.

File sharing: this is used for sharing file documents in a firm.
II. Resource sharing: Documents are easily shared in a firm such as email.
III. It creates efficiency among employees in a firm.
IV. It increases the storage capacity: That is, the storage capacity of a computer is increased such that data from the internet can be stored.
V. It allows users to conduct voice and video calls. You are able to see the person you are communicating with no matter the place.
VI. It allows the sharing of software. It is easy to install and update software on the computer. This makes it cheaper for some companies.
VII. It makes easy for users to obtain a final report of their tasks performed by supercomputers. The data is returned via the network to the workstation for the user to have a final report.
