2. Review: ones & twos complement

Research ones complement and twos complement, write in your own words: What are they, why use them, and examples. The complement 1 has two representations of 0 (zero) - 000000000, which is positive zero (+0) and 11111111111, which is negative zero (-0); However, in the addition of 2' there is only one representation for zero - 0000000 (+0), because if we add 1 to 111111 (-1), we get 0000000 (+0) the same as positive zero. For this reason, complement 2 is usually used.

3. Desktop vs Server Operating System a. Describe a desktop operating system and a server operating system, and briefly mention how these two are different from each other. Desktop Operating System are those types of operating systems which are installed on a Desktop Computer or a Personal Computer which can only be used by an individual at a time. Server Operating Systems are those types of operating systems which are installed on powerful computer which is connected to a network and on these types of OS multiple users could perform different task and access the information at the same time. In Desktop Operating System, it can only be used by one user at a time and these are generally used for personal use. Whereas Server Operating System is used for business and commercial purpose which allows multiple users to access the information from the main server. But in order to access the information from the server, other users and server itself must be connected to internet. b. Discuss some different types of server hardware that might run a server operating system that would distinguish it from a normal desktop setup.

The followings are the types of server hardware that might run a server operating system that would distinguish it from a normal desktop setup: Processor: they have a very high processing processors. Memory: These Operating system has very high memory capacity as well and you could find few spaces which are left empty for further extension of the memory if needed. Storage: most of these Operating systems have SATA or SCSI hard disks. 4. Devices and drivers a. What is a device driver? A device driver is a software or a computer program which controls or runs a physical device/ hardware. For us to be able to use the mouse, pint and click and open the files and folders, a device driver software is used. b. How do operating systems use device drivers? Device drivers are used by the operating systems to communicate with the peripheral devices which then makes the peripherals function. c. What devices might require device drivers?

All the Input/ Output devices might require device drivers such as a printer, keyboard, Scanner etc. 5. You are going to find, download and run a program called ‘PC building
