b. The CPU reads all RAM sequentially, beginning with the first byte, until it happens to read the byte that the CPU wanted to read. c. The smallest unit of data that RAM supplies back to the CPU is 1 bit. d. The CPU must first find the file in the file system before reading the data. 6.
Technically RAM does not have an influence on the processor performance, but it does have an influence on how much processes or technically instructions that processor can read. So a greater amount of RAM memory means that more instructions fit into that memory and therefore, bigger programs can be loaded at once. (Computer) Allowing the operating system to work with a multitasking concept, where we can run multiple programs at once. To explain how it works, you have 128MB of RAM on your computer and you need to load up multiple programs that are 512MB. That means you would have slowness as it has to load a piece of that program, then it has to refresh, then load up the rest of the program.
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?
UNIT 1 ASSIGNMENT 1 1) R.A.M- Stands for (random access memory). This is a type of computer memory that can be accessed randomly. RAM is the most common type of memory found in computers and other devices. 2) O.S.-(operating system) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system.
Its disk overhead requires all of its drives to be running. Its 100% redundancy means that no data will be lost. 6. If you, as a home computer user, were to purchase a form of RAID, which would you choose and why? It depends on why I need the RAID.
(Choose two answers.) a. Used for short-term memory e. Is installed onto the motherboard 5. This chapter describes the concepts behind how a CPU reads the contents from RAM. Which of the following is true about the process of read data, as described in the chapter?
Which of the following statements is not true of file processing systems? a.|the records in one file relate to the records in other files| b.|they have redundant data| c.|they isolate data| d.|maintenance tasks consume additional time| ____ 15. Which statement does not apply to the database approach? a.|it requires less memory than file processing systems| b.|it increases the data’s integrity| c.|programs are easier and faster to develop than with a file processing system| d.|it allows nontechnical users to access and maintain data| ____ 16. Which of the following DBMSs will run only on a server or mainframe?
Week 1 Memory Management Requirements Maurice E. Northam III POS/355 February 23, 2015 Brando Saymao Week 1 Memory Management Requirements Subdividing memory to oblige various techniques helps in memory management. Memory needs to be allotted to guarantee a sensible supply of prepared methods to devour accessible processor time. Developer does not know where the project will be set in memory when it is executed. While the project is executing, it might be swapped to plate and came back to primary memory at an alternate area (moved). Memory references must be deciphered in the code to real physical memory address.
Also we know that more processes running on your computer will in general mean less CPU’s horsepower available for other tasks. This means you should first have a look at the running services on your computer and determine if they are really necessary. For example is it really necessary that your TomTomHOMEService used for ejecting TOMTOM devices runs automatically or can you may be set it’s start up type to manual in the Windows 7 in Control Panel > System and Security > Administrative Tools > Services list? A less obvious factor which can affect your computer’s performance is the fragmentation on the hard disk drive, making it more difficult for the system to build up the data it needs to run you applications in memory if the composite data are scattered all over the hard disk drive. In the System Section under the Control Panel in Windows 7 is a section called “Check the Windows Experience Index” which is a nice step up from the situation
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.
