Data modeling

to help the computer system to work. Hardware - Is a physical component that contributes to the build of a computer system. For example… Processor, Main memory, Secondary Memory, Input Devices, Output Devices Software - Is computer programmes and data that help provide the BIOS instructions for telling the hardware what to do and how to do it. For example… the operating system is the most obvious system software.…

Whenever I have a seat at my desk and gaze into the void, black screen, I am overwhelmed with the thought of the steps it took me to get there. I try to comprehend the endless codes, commands, pieces, and elements that exist in this mad thing I created. The thought of a traitor, whom I believed in as a mentor and followed, continues to haunt me. In my adoration of processors and motherboards, I experience infinite memories haunted by him. I often ask myself if I have created a monster or become…

Like random access memory, there is a necessity within the technology industry to make ultra-high density disk drives. Companies from multinationals to small businesses store all their information in these drives. As time passes, more data is created and more data needs to be stored. Hence, more storage is needed. This need for storage increase is essential for the electronic materials industry, as it drives the technology world forward and results in the discovery and making of new…

step is that of acquisition. However, the method used for data acquisition by a forensics investigator plays a major role in influencing the admissibility of electronic evidence to be used in a court or law, or the reliability of any other relevant information required when dealing with computer forensic cases at the organizational level (Dykstra & Sherman, 2012). Different data acquisition techniques allow for the recovery of electronic data from devices like hard drives, databases, web server,…

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…

Design Analysis A connection is recognized in the optical layer regulates to carry the information among the clients in the network. The optical connection is preserved between a source node, s and destination node, d is known as an light path. The problem in finding a route for a light path with wavelength assigned to the light path is submitted as the routing and wavelength assignment problem (RWA). The problem of RWA is divided into two parts : Routing and Wavelength Assignment. In the…

(1.) A. B. 2. (3.) The percentage of Allison’s egg cells that she produces during her lifetime that will carry the recessive allele and the X chromosome is seventy five percent. For the fact, twenty five percent of the cell will carry homozygous recessive allele and X chromosome, the other fifty percentage will carry heterozygous recessive allele and X chromosome. (4.) A. Twenty Five Percent B. No. C. (X)R (X)r (X)R (X)R(X)R - Female homozygous dominant (X)R(X)r…

before. Also, it comes with a 1TB hard drive or if you want an even faster application/files response, you can choose the 1TB Fusion Drive which automatically puts the data that you use the most in the faster flash storage and the others to the hard drive. 1TB is a really good capacity for a graphic designer considering all the data you need to save every day. However, if you need more capacity you can upgrade to 3TB.…

There are many parts inside of a computer and multiple steps in building a computer. If a problem occurs when building a computer, then it can be from one thing or from many different things. It can be from something as easy as a misplaced part or a bent pin on the CPU socket. I am building a computer at this moment and I have been confronted with errors already. The error I was accosted with was that the computer would not turn and show the error code “55” on the motherboard.This could mean…

1. The advantage of using a very large memory cell size is that the computer can store larger values in its memory cells. The disadvantage is that there would be fewer cells available. 2. This question asks how many bits are needed in the MAR with the following numbers a. 1 million bytes = 20 bits b. 10 million bytes = 24 bits c. 100 million bytes = 27 bits d. 1 billion bytes = 30 bits 3. 640 kb would be 655,360 memory cells. A 512MB would contain 536,870,912 memory cells. A 2GB would contain…
