Course Description An introductory course designed to provide students with a fundamental understanding of computers. The course familiarizes students with the interaction of computer hardware and software. Emphasis is placed on the application of microcomputers, the use of productivity software (word processing, spreadsheet management,
Hard disk drive c. Optical disc drive d. USB flash drive 15. A user has opened a word processor, typed the numbers 123456789, and looked at the number on the screen in the word processor window. The user sits and starts to daydream about how computers work, particularly about what happened from the time before she typed 123456789 until the number showed up on the screen. Which of the following answers lists the first item that the computer will need to consider? a.
6.Synchronous DRAM, a type of DIMM memory that synchronizes itself with the computer’s system clock to provide a synchronization between the memory and the computer processor. 7. The primary benefit of DDR3 is the ability to transfer I/O data at eight times the speed of the memory cells it contains. DDR3 standard allows for chip capacities of 512 megabits to 8 gigabits, effectively enabling a maximum memory module size of 16 gigabytes. 8.
LO4: Explain how programs work. LO5: Differentiate among machine language, assembly language, and high-level languages. LO6: Differentiate between compilers and interpreters. LO7: Identify the different types of software. LO8: Determine program input, processing, and output stages.
-1024KB*120=122880 122880KB*1024=125829120B Exercise 1.3.4 Given a computer with a disk capacity of 16 GB and a word size of 32 bits, how many words can be stored on the disk? Show your calculations. -16*1024MB=16384MB -16384MB*1024KB=16777216KB -16777216KB*1024B=1.71798918E10 -1.7179891E10/32=536870912 words Exercise 1.3.5 Represent the binary value 110110 2 in hexadecimal. Show the steps of conversion that you used. -0011 0110 0011 represents 3 0110 represents 6 - 36 Exercise 1.3.6 Represent the hexadecimal value f6 16 in binary and decimal.
3. Provide a comparison table showing the similarities and differences between desktop and notebook computers. Task1: Here are the functions of the each component in the Von Neumann model of the computer Component Function Control unit The control unit will manage the process of moving date and program that data. In modern computers this memory is RAM. Arithmetic logic Unit This part of the architecture is solely involved with carrying out calculations upon the date.
W1A1 Megan Murphy Herzing University Personal computers consist of a main processing unit, the keyboard, mouse, RAM, hard disk, DVD drive, and monitor to make it functional. The keyboard is used to input your words, information, and commands into the computer. The mouse is used to navigate around the screen. RAM or random access memory is a memory component. RAM is used for temporary storage of data and that data erased after exiting software or rebooting or turning off the computer.
Chkdsk: This tool checks the integrity of the harddrives in your machine this tool can check and correct errors found on the local harddrive. The tool can be launched from a command prompt by opening the command prompt and typing in chkdsk. Chkdsk has many options such as chkdsk /f. This command will fix the errors found when you run just the standard chkdsk this only report the status of the harddrive. Next tool on our list is the disk defragmenter tool.
