Answer:

1) The main features of fourth generation are-

- VLSI technology used

- very cheap

- portable and relable

- use of PCs

- very small size

- pipeline processing

- no AC required

- concept of internet was introduced

- great developments in the fields of networks

- computers became easily available

2) Transistors:-

- lower power consumption, less wastage of heat .

- size is so small as compared to vacuum tubes.

- low cost.

- easily portable device.

Vacuum tubes :-

- power consumption is high and heat wastage is comparatively high.

- large size than transistor.

- high cost.

- less suitable for portable products.

3) Computer are classified on different parameters, such as, storage capacity processing speed and component (CPU) used in computers. Depending upon the components used and features of different computers, they are classified into four groups microcomputers, minicomputers, mainframe Computers and super computers.

4) mainfrane compcomputers are large and expensive machines. The word length of mainframe computers may be 48, 60 or 64 bits , memory capacity being in some megabytes and storage capacity in some terabytes . Generally they handle huge volumes of information and data. In terms of speed , they are having significant processing capacity. they are used in research organization , large database has to be maintained.

5) Minicomputers were introduced in 1960s . They were faster than micro-compuers . Basically these computers were mainly multi user system , where many userusers work on the systemsystems. Generally these types of computers had larger memories and greater storage capacity . They had large instruction set and address field. These kindkinds of computers have efficient storage for handling of text , in comprision to lower bit machines. Due to more efficient processor , speed and memory size , minicomputerminicomputer was used in variety of applications and could support business applications along with the scientific applications . MinicomputerMinicomputer was a multi-user system which means more than one user could use this system simultaneously.

6) Windows explorer is the file management application in windows . Windows explorer can be used to navigate our hard drive and display the contents of the folders and subfolders we use to organize our files on our hard drive . Windows explorer is automatically launched any time we open a folder in windows XP.

7) The different view formats are draft , print preview , web book view. Print preview - the default viewing format is print preview format. Book view - the way we read a book is called book view. The different views in MS word are full screen reading view , outline view , web lay out view , etc.
