Question

Write your answers after completing the lab, but read them carefully now and keep them in mind during the lab. Computers are unique in that they are general-purpose devices. In other words, they were not designed for a very specific purpose, the way a watch is designed to keep time and a dictionary is designed to provide definitions. As it turns out, however, computers can certainly both keep time and provide dictionary definitions. Name three other special-purpose devices or objects (not necessarily electronic) which do things that computers can also do with the appropriate software and/or hardware. RAM and hard disks are both forms of data storage. How are they alike? How are they different? In particular, discuss the relative advantages and disadvantages of each. Describe at least one non-computing example of hierarchical organization in the real world something like the geography example given in the lab.

Explanation / Answer

1. These days technology has advanced to such an extent that using a traditional desktop pc or even a laptop is becoming a thing of the past. Nowdays many devices are being developed that work just like computer, with a proper software, memory and other hardware these devices are doing wonders. Here is a list of three devices which work like computer:

2.

There is not much similarity between ram and harddisk just the fact that both are storage devices.

ADVANTAGES OF RAM

DISADVANTAGES OF RAM

ADVANTAGES OF HARDDISK

DISADVANTAGES OF HARDDISK

3. one real life example of hierarchical organisation can be a bussiness firm

the hierarchy followed in a business firm is

at the top is the board of directors who pass day to day to instructions to the one level below managing directors or CEOs who further pass the instructions to the department managers who get the work done from the desk employees and the workers

RAM HARDDISK temporary data is stored in ram permanent data is stored in hrd disk it erases the data once the computer is shut down it keeps the data permanently, only the computer user can add or delete data in a harddisk it is of two types sram and dram harddisk has no further types ram is a small chip containig multiple circuits harddisk is complete machine with parts like platters,read write head, plastic disk,mangnate writer while working on computer the immediate memory used is ram, all the data required to perform a task at a single time is stored in ram harddisk is a secondary storage when it comes to storing the data for particular task, hard disk is used for storing long term data the speed of ram is fast, the speed of computer depends on the speed of ram the speed of harddisk is slow, the speed of computer is not much affected by the speed of the harddisk
