Module 3 Computer Storage Systems Lesson1 Download Free Pdf • all data stored on storage media – whether that’s hard disk drives (hdds), solid state drives (ssds), external hard drives, usb flash drives, sd cards etc – can be converted to a string. The input output mechanism however remained largely unchanged. second generation computers were programmed using a symbolic or assembly language. the computers also implemented the stored program concept which allowed both program and data to reside in memory.
Chapter 1 Computer Storage Pdf Storage capability memory is a very important characteristic of computers. a computer has much more storage capacity than human beings. it can store large amount of data. it can store any type of data such as images, videos, text, audio, etc. A number of different types of devices are available for data storage on a pc, as shown in the figure. data drives provide non volatile storage of data, meaning that when the drive loses power, the data is retained and available the next time the drive is powered on. Solid state drives (ssd) store data as electrical charges in semiconductor flash memory. this results in faster access to data, improved performance, higher reliability, reduced power usage. In this lecture we explore computer memory. we begin by looking at the basics. all memory is numbered, with each byte having its own address. we take a look at the random access memory (ram) that composes most of main memory.

Computers do you want a computer? we can give you a refurbished internet capable desktop computer (internet service connection not included). only one per household pickup in wheaton computer repair services are free. “computer hardware and basic functions” module provides information regarding the main physical components of a computer and laptop as well as the basic functions. Explore how much storage is needed for different types of data by conducting online research or using available storage calculators to investigate the storage requirements for a movie, a mobile phone photo, and a popular video game. This unit is used to store programs & data. there are 2 classes of storage: primary storage is a fast memory that operates at electronic speed. programs must be stored in the memory while they are being executed. secondary storage is used when large amounts of data & many programs have to be stored. eg: magnetic disks and optical disks(cd roms).
