NT 1210 Chapter 1 2. Which of the following terms means approximately 106 bytes? Megabyte 5. This chapter describes the concepts behind ho a CPU reads the content from RAM. Which of the following is true about the process of read data, as described in the chapter?
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.

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.
How does this compare to the individual values of Byte 1 and Byte 2? The decimal equivalent of the binary sequence is 6,633 which is the sum of the values of byte 1 and byte 2. Exercise 1.3.3 Given a device with a storage capacity of 120 MB, how many bytes can be stored on this device? Show your calculations. 120 MB x 1024 = 122,880 KB x 1024 = 125,829,120 bytes 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?
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.
-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.
Unit 1 Assignment 1 Why is the CPU the most important component in a computer? The CPU is the part of the computer that actually runs the programs What number does a bit that is turned on represent? What number does a bit that is turned off represent? 1 represents a bit that is turned ON. 0 represents a bit that is turned OFF What would you call a device that works with binary data?
The AMD SB710 Southbridge chipset is used with Socket AM3/AM2 Processors, AMD Turion™ II Neo | AMD Athlon™ II Neo Processors (ASB2),AMD Turion™ Neo, AMD Athlon™ Neo and AMD Sempron™ Processors (ASB1). Its purpose on the motherboard is to control the processes that are going on within the computer's main frame system. 3. The Socket AM3 Connector is used with the same AMD SB710 Task 3 procedure 1.
