a) What types of files might you want to copy to the cloud? Why would you copy files to
the cloud instead of copying them to an external storage device?

b) How does the access time of storage compare with the access time of memory?

c) End user programs are designed for specific functions such as word processing or a
game. You have installed a new piece of applications software onto a stand-alone PC.
You then find that the printer attached to the PC fails to produce what can be seen on
screen in that package. Explain clearly why this might happen.

Define .svg, .ps, .ai, and .eps.  Describe how these file formats are used in web design?

A local online bitcoin wallet company, Luno is running out of capacity and performance with the current storage system. Luno has decided to own a RAID system at a reasonable cost to increase the speed, capacity, availability and scalability of the trading activities.

(a) Recommend a suitable RAID system for Luno. Provide your strong justifications.

A young child wants to jump over a puddle. The caregiver agrees, but has conditions: “you can jump until you are tired but you cannot jump over the puddle more than 15 times”.

Can someone write this to me in pseudo code and flow chat please thanks

please use c

write a program that utilizes pipes for Interprocess Communication (IPC). The program will create a pipe(s) to allow the parent and child to communicate.

The parent process will generate a random number based on the pid of the child process created. The parent will send this random number to the child and wait for a response (Received) from the child. After receiving a response from the child, the parent will send another message to the child telling the child it is okay to end. This message should be “BYE”.

The child process should wait to receive the random number from the parent. After receiving the random number, it should send a response back to the parent. This message should be “Received”. The child should then wait for another message (BYE) from the parent indicating it is okay for the child to end.

Both processes should print to standard output the message it will write to the pipe and any message it receives from the pipe. Each message printed should be the process (“Parent” or “Child”) and if the message will be sent to the pipe or if it was received by the pipe. Example output might be similar to this:

Parent sending to pipe: 784392

Child received from pipe: 784392

Child sending to pipe: Received

Parent received from pipe: Received

Parent sending to pipe: BYE

Child received from pipe: BYE

Make sure you follow good programming practices, such as the use of functions, closing file descriptors as soon as not needed, in-line comments, error checking, freeing dynamic memory, etc.

use any programming language that allows the creation of new processes similar to the fork() system call in C and the use of pipes similar to the pipe() system call in C.

As part of the duties of a digital forensics examiner, creating an investigation plan is a standard pactice. Write a paper that describes how you would organize an investigation for a potential fraud case. In addition, list methods you plan to use to validate the data collected from drives and files, such as Word and Excel, with hashes. Specify the hash algorithm you plan to use, such as MD5 or SHA1.

2.3At the lowest level of processing, we manipulate bits in the framebuffer. In WebGL, we can create a virtual framebuffer in our application as a two- dimensional array. You can experiment with simple raster algorithms, such as drawing lines or circles, through a function that generates a single value in the array. Write a small library that will allow you to work in a virtual frame- buffer that you create in memory. The core functions should be WritePixel and ReadPixel. Your library should allow you to set up and display your vir- tual framebuffer and to run a user program that reads and writes pixels using gl.POINTS in gl.drawArrays.

2.4 Turtle graphics is an alternative positioning system that is based on the concept of a turtle moving around the screen with a pen attached to the bottom of its shell. The turtle’s position can be described by a triplet (x, y, θ), giving the location of the center and the orientation of the turtle. A typical API for such a system includes functions such as the following: init(x,y,theta); // initialize position and orientation of turtle forward(distance); right(angle); left(angle); pen(up_down); Implement a turtle graphics library using WebGL.

Access control can be considered as the central element of computer security. Question 4(a), 4(b), 4 (c) and 4(d) based on this information.

4 (a). Relate the principal objective of computer security with the function of access control.

4 (b). Briefly explain how access control being implemented in the machine.

4 (c). If Process A requires 500MB of memory space to perform calculation and Process B requires 100MB of memory space to perform graphics processing, identify the object, subject and access operation in this scenario. Provide explanation for your answer.

4 (d). Company RT wants to have different access levels for each of its users. A management level employee will have more privileges to files and operations. The executive level will have moderate privilege to the files but individual users will have their own level of control to the files they own. Which type of access control is suitable for this company and its employee? Clearly explain and justify your answer.
