8) U.S.B. - (Universal Serial Bus) is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices. 9) H.D.D.-(Hard disk drive) is a data storage device used for storing and retrieving digital information using rapidly rotating disks coated with magnetic material. HDD retains its data even when powered off. Data is read in a random-access manner, meaning individual blocks of data can be stored or retrieved in any order rather than
RAM is used for temporary storage of data and that data erased after exiting software or rebooting or turning off the computer. Hard disk is permanent storage device for the computer. (Ingberg, 2009) DVD drive is another component that is important for you to install software or store data to a CD or DVD disk. (Ingberg, 2009) There are different types of hardware. There is the
See signal-to-noise ratio. Fundamental physical limits such as the shot noise in components limits the resolution of analogue signals. In digital electronics additional precision is obtained by using additional digits to represent the signal; the practical limit in the number of digits is determined by the performance of the analogue-to-digital converter (ADC), since digital operations can usually be performed without loss of precision. The ADC takes an analogue signal and changes into a series of binary numbers. The ADC may be used in simple digital display devices e. g. thermometers, light meters but it may also be used in digital sound recording and in data acquisition.
Which of the following answers best describes how a hard disk drive physically writes a binary 0 or 1?C. changing the disk’s surface 12. Which of the following answers are true about an internal hard disk drive (HDD) as it is normally used inside a personal computer (choose 2) B. used for long-term memory, D. connects to the CPU over a bus using a cable
4. A (n) Printer Driver is one file or set of files containing information that Windows XP Professional requires to convert print commands into a specific printer language, such as Post Script. 5. Windows XP Professional printing supports which of the following types of computers? Ans.
Because it is logical based rather than being tied to the hardware, everything is file based, which makes it more secure. And finally, the fourth advantage of Linux is that it was built to support multiple users. So it can run multiple tasks with many different users
2. The reason you would want to limit the type of incoming connections to your computer is because if there is too much traffic flowing in it can slow the performance of your computer. 3. A peer-to-peer network allows network devices to share resources and communicate directly with one another without the use of servers. The benefits of using peer-to-peer are that it is secure, scalable, serverless, self-tuning, self-repairing, and sharing.
Which of the following is true about the process of read data, as described in the chapter? a. The CPU tells the RAM which address holds the data that the CPU wants to read. 6. A user has opened a word processor, typed the numbers123456789, and stored the document as a file called report1.
Which of the following is true about the process of read data, as described in the chapter? D. The CPU must first find the file in the file system before reading the data. 6. A user has opened a word processor, type the numbers 123456789, and stored the document as a file called report 1. Which of the following determines, in part, what bits the computer stores in the file to represent the text typed into the report?
Security Authentication CMGT/400 Intro to Information Assurance & Security November 17, 2014 Troy Adams Security Authentication Securing data has become one of the most important things in the age of computers. The process of authenticating users has become a full-time job for some IT professionals. To understand all that it involves we should first understand what it means. Rouse (2004-2014), "Authentication is the process of determining whether someone or something is, in fact, who or what it is declared to be” (para. 1).
