CSL333 Operating Systems Homework -1 Q 1.1 : How are network computers different from traditional personal computers? Describe some usage scenarios in which it is advantageous to use network computers. Answer : A network computer has a minimal operating system and mostly depends on the central server for the services. While a personal computer functions in a standalone manner providing all the required functionality. In network computer people can copy files from one machine to another, hence it is not secure like the personal computer. They are preferred at places where sharing of resources and data is required.
Q 1.12 : What are the main differences between operating systems for mainframe computers and personal computers? Answer : Batch systems do not have to be concerned with interacting with a user as much as a personal computer. As a result, an operating system for a PC must be concerned with response time for an interactive user usually at the expense of efficiency. Personal computer operating systems are not concerned with maximal use. Mainframe computers have higher I/O capacity and they need more complex algorithms to keep the system components busy for maximum output.
Q 1.15 : Identify several advantages and several disadvantages of open-source operating systems. Include the types of people who would find each aspect to be an advantage or a disadvantage. Answer : Open-source operating systems have the advantage of having many number of people working upon, ease of distribution, many people debugging codes, and faster updates. And students and programmers can view and modify the source code. They are free to use compared to the commercial operating systems. Some companies prefer commercial operating systems which provide paid support, so that they have someone to hold accountable when they face problem. Backward compatibility is lacking making upgrades difficult.
Q 1.21 : Define the essential properties of the following types of operating systems: d. Real time
Answer : These operating systems are used for dedicated application. They take information from the sensors and must repond within a fixed time interval for correct operation.
f. Parallel Answer : These operating systems are used in computers where multiple CPU’s are running the same operating system sharing information using the system bus. i. Handheld Answer : These operating systems are used in smaller systems which are used for simple purposes like web browsing, email, calendar. Compared to traditional systems, they have smaller memory and processing power.
