A user has opened a word processor, typed the numbers 123456789, and stored the document as a file called report1. Which of the following determines, in part, what bits the computer stores in the file to represent the text typed into the report? c. Character set 7. A user has opened a calculator application, typed the numbers 123456789, and then done some math problem using this number. Which of the following determines, in part, what bits the computer stores in RAM to represent the number 123456789?
A. an actuator arm 9. A student writes a report using a word processor, saving the report in a file called my_report. The student stores the file on his laptop hard disk drive. Later, he posts the file on a file-sharing site for a classmate to review the report. Then, he copies an updated version of the file to a flash drive to submit it to his instructor.
A. Used for short-term memory E. Is installed onto the motherboard 5. A. The CPU tells the RAM which address holds the data that the CPU wants to read. 6.
Relocation, sharing, physical organization, protection logical. What kind of memory address does a central processing unit (CPU) generate? Logical address What kind of memory address does a memory management unit (mmu) generate? Physical address What is the process of loading a process from secondary memory into primary memory? Input/ output channel from transferring data Homework -What are three main purposes and operating system?
Week 4: Computer Architecture A computer is an electronic device that operates under the control of instructions that are stored in memory. The concept of storing memory or instructions within the computer came from John Von Neumann. Von Neumann architecture is best described as a stored program design. A stored program design means that the program that operates the computer and the instructions that carry out the program are stored on the computer in one location called memory. By having a stored program design, the computer doesn’t have to go through a rigorous process to be reprogrammed, or to perform multiple functions.
a. ENIACs b. microprocessors c. memory chips d. operating systems 5. The computer stores a program while the program is running, as well as the data that the program is working with, in __________. a. secondary storage b. the CPU c. main memory d. the microprocessor 6. This is a volatile type of memory that is used only for temporary storage while a program is running. a. RAM b. secondary storage c. the disk drive d. the USB drive 7.
The unit can compare numbers, letters, or special characters. The computer can then take action based on the result of the comparison. It then has a memory unit which allows the CPU via the operating system to calculate the amount of memory needing to be allocated to each programme and where to put the memory in use if unallocated. The processor can also control backing storage this is sometimes knows as secondary storage this is the name for all other data storage devices in computer i.e. a hard drive, etc.
Firmware is software contained in ……. chips. 7. Instructions that control much of the computer’s input/output functions, such as communicating with disks, RAM, and the monitor kept in the System ROM chips, are known as the……. .
In this architecture, various tasks are founded on binary instructions that are taken from a storage device. The data is then transmitted by the CPU (this is referred to as the fetch-execute cycle). Von Neumann is accredited for conceiving and assembling computers founded on three attributes: (1) that the computer is comprised of four main sub-systems: memory, ALU (Arithmetic / Logic Unit), Control Unit, Input / Output and System (I/O), (2) that programs are kept in memory while executing; and (3) that data / computer instructions are implemented consecutively. Von Neumann met with wide acclimations regarding the stored program computer with the components of memory and the control unit (Karwatka, 2005). These features are utilized today in all computers and many
(Passer & Smith, 2007, p.234). This metaphor broke memory down into three simple processes: encoding, storage and retrieval. Encoding: the translation of information into a neural code for the brain to process just like a keyboard translates key strokes into electrical codes for a computer. Storage: the retaining of information just as the RAM (random access memory) or hard drive retains information in a computer. Retrieval: the process in which stored information is accessed by the brain similar to that of a software command that opens a file from the hard drive on a computer.
