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?
-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.
Used for short-term memory b. Used for long-term memory c. Used to process data d. Connects to the CPU over a bus using a cable e. Is installed onto the motherboard 13. Which of the following are components of an internal hard disk drive (HDD)? (Choose two answers.) a. Actuator arm b. Laser c. Platters d. Sliding media tray 14.
Next tool on our list is the disk defragmenter tool. This tool moves the clusters of a hard drive to make one continuous cluster. When a program is deleted off of a machine is fragments the harddrive leaving the clusters in different parts of the harddrive when a defrag is ran it takes all the fragmented clusters and makes them all one. You can run this manually by performing the following steps. Click Start, and then click Computer.
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.
What value is stored in uninitialized variables? An uninitialized variable is by default a 0. Algorithm Workbench 3-10 3. Write assignment statements that perform the following operations with the variable a, b and c. a) Adds 2 to a and stores the result in b. { b = 2 + a } b) Multiplies b by 4 and stores the result in a.
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.
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.
