Magnetic tape data storage

Introduction This week long course is intended to educate learners on the topic of computer technology, including computer hardware, computer software, and its effect on everyday life. Included in this course document are three evaluation strategies: a diagnostic evaluation, a formative evaluation, and a summative evaluation. The diagnostic evaluation that is included is a pre-assessment. The pre-assessment will be completed preceding the beginning of the course to determine the students’ prior…

We’ve used a lot of devices and storages so far in our life, but one thing that might be weird to people is the RAID. RAID stand for redundant array of independent disks and is a place for people to store their information. It is stored on CDs, instead of the normal flash drives and hard drives. RAIDS are different from the normal CDs, because they have to divide the data and spread the blocks into several megabytes for RAID to work. This is to make RAID efficient and fast. There are lots of…

Part A: Textbook p293 Exercises 9.4 Consider the interrupt that occurs at the completion of a disk transfer. a. Direct memory access (DMA) is an alternative method that avoids the use of the CPU by allowing direct data transfers between memory and I/O devices or peripherals. Once the data is transferred the CPU is notified of the transfer completion and able to resume access of the main memory. It is able to do this with interrupts; are signals that are generated once an action is completed.…

provide a full back up of the entire estate that was originally implemented over 7 years ago. Due to the increasing growth of data within the infrastructure the backup solution has become unfit to deal with regular backups and is now struggling to successfully complete the daily backup policies within a 24 hour period. Recently the IT team initiated a review of the capacity of data being backed up to overcome some of the issues but was unable to reduce the total size sufficiently to maintain…

relevance to D flip flop Memory is an electronic data storage device which is usually implemented on a semiconductor based integrated circuit. The basic operations accomplished by a memory chip are READ in which the data contents of a memory is read out and WRITE in which data is stored in a memory. Each bit of information bits is stored in memory cell consisting of one or more transistors. The most basic such memory unit which stores 1 bit of data is the D flip flop. High performance IC…

Introduction I am the information security specialist for a company that develops software X. Software X is the leading operating system in mobile devices. Unfortunately, our company believes Mr. McBride, a former employee stole product X source code for financial gain. As such, I have been tasked with leading the forensic investigation in this matter.

LARGEST database of biometric data. This includes retina scans, fingerprints, and multiple facial images for not one but each individual. This to me…

Computers provide avenues for creating, viewing, distributing, modifying, and preserving digital media. Examples of digital media include computer software and programs, digital video, digital imagery, websites, and web pages. These are inclusive of data and databases, social media, e-books, and digital audio. A combination of the internet, computers, and digital media can have significant impacts in publishing, entertainment, journalism, commerce, education, politics and businesses.…

1.0 Introduction A computer is an electronic device that manipulates information, or data. It was originally given to humans who performed numerical calculations using mechanical calculators, such as the abacus and slide rule. It has the ability to process, store and retrieve data and not only that a computer can also be used send to email, browse the internet for information, saved soft copy documents in the hard disk. The great advantages is it can perform multiple task such accounting formula…

systems do this automatically. _ The Raspberry Pi always boots from an SD card. It means that even a perfectly valid installation of an operating system is available on a USB stick or an external hard drive, it can’t be booted. In other words, external storage devices can be used but can’t be used to boot the Raspberry Pi. _ It does not support Bluetooth or WiFi out of the box but these supports can be added by USB dongles. _ Unfortunately, most Linux distributions are still a bit picky about…
