What are the advantages and disadvantages of graphical user interface (GUI) and why would some users find (GUI) attractive while others would not? (10 points);---------------------------------------------;3. Describe the differences between, and the advantages of, sequential access files and random access files. (10 points);--------------------------------------------;4. What is the difference between an ISP and a POP? (10 points);--------------------------------------------;5. What are some advantages of layering as seen in the TCP/IP architecture? (10 points);--------------------------------------------;6. What is HTTPS? (10 points);--------------------------------------------;7. Define and briefly compare the advantages and disadvantages of ?fat client? and ?thin client? architectures. (10 points);-------------------------------------------;8. Provide three examples (each) of elastic and inelastic Internet traffic. Justify each example?s inclusion in their respective category. (10 points);************************************;Multiple choice: (10 points total ? 2 points for each question);(Please select the correct answer).;9.1 Systems in which one or more processes are able to access the CPU immediately when required are described as;a) single-user systems;b) multiuser systems;c) network servers;d) real-time systems;e) distributed systems;Answer;-----------------------------------------;9.2 Levels of security for each file provided by UNIX include separate read, write, and execute access privileges for;a) owner;b) associates of the owner;c) anybody with access to the system;d) a and b;e) a, b and c;Answer;------------------------------------------;9.3 The value of adding more CPUs to a computer ?..;a) is only appropriate for scientific applications;b) is not practical;c) decreases the need for cache;d) increases the performance in a linear fashion;e) diminishes because of the overhead required to distribute the instructions in a useful way;Answer;---------------------------------------------;9.4 A paradigm for electronic communications where a dedicated path is opened and maintained during the exchange is called;a) message switching;b) circuit switching;c) packet switching;d) data switching;e) analog switching;Answer: B;-------------------------------------------------;9.5 A device that connects networks with differing addressing schemes, packet sizes, and interfaces is called a;a) hub;b) router;c) switch;d) repeater;e) bridge;Answer: B;**************************************;True/False (10 points total ? 2 points for each question);(Please answer True (T) or False (F)).;10.1 Initial program loading and start-up is performed by using a bootstrap program that is built permanently into a read-only part of memory for the computer.;Answer: True;--------------------------------------------;10.2 To use the program services routines, the user?s program makes requests to the operating system through the application programming interface or API.;Answer;--------------------------------------------;10.3 Removing a file without removing the links leaves dangling links, links that point to nowhere.;Answer;--------------------------------------------;10.4 Hosts connected to the Internet are identified by a unique 24-bit number that identifies a network and specific host within that network.;Answer;------------------------------------------------;10.5 An internet routing protocol is used to exchange information about reachability and traffic delays, allowing each router to construct a next-hop routing table for paths through the internet.;Answer
