installment payments on your IDENTIFY THE CHARACTERISTICS OF THE 1ST FIVE TECHNOLOGY OF COMPUTER SYSTEMS. The main features of First Era are:

5. Vacuum pipe technology

* Unreliable

* Supported Machine language simply

* Very expensive

* Generate lot of high temperature

* Sluggish Input/output system

* Large size

2. Need of any. C.

* Non portable

* Used lot of electrical power

The main features of Second Generation are:

2. Use of transistors

* Trustworthy as compared to 1st generation personal computers

* More compact size when compared with First technology computers

2. Generate much less heat as compared with First era computers * Consumed much less electricity in comparison with First era computers 5. Faster than first technology computers

* Still very expensive

* A. C. needed

* Support machine and assmebly 'languages'

The main features of Third Generation are:

2. IC applied

* Very reliable

* Small size

2. Generate fewer heat

5. Faster

5. Lesser routine service

* Still costly

* A. C needed

5. Consumed smaller electricity

2. Support dangerous language

The primary features of Last Generation happen to be:

* VLSI technology used

* Very cheap

* Lightweight and dependable

* Use of PC's

2. Very small size

* Pipe processing

2. No A. C. needed

* Concept of internet was introduced

5. Great developments in the areas of sites

* Personal computers became easily available

The main highlights of Fifth Generation are:

2. ULSI technology

* Advancement true manufactured intelligence

* Development of Natural language digesting

* Improvement in Parallel Processing

* Advancement in Superconductor technology

* More user friendly interfaces with multimedia features

2. Availability of extremely powerful and compact computers by cheaper costs Mainframe computers (colloquially termed as " big iron"[1]) are computers applied primarily by simply corporate and governmental businesses for critical applications, large data control such as census, industry and consumer stats, enterprise source planning and transaction control. A Micro computer is actually a complete computer on a small scale and is generally a synonym for the more common term, personal computer or perhaps PC, your computer designed for a person. A microcomputer contains a microprocessor (a central finalizing unit on a microchip ), memory in the form of read-only memory space and arbitrary access memory space, I/O slots and a bus or system of interconnecting wires, encased in a unit that is usually called a hauptplatine. Minicomputer (colloquially, mini) is known as a largely out of date term for any class of multi-user pcs which make in the middle range of the processing spectrum, in the middle the largest multi-user systems (traditionally, mainframe computers) and the littlest single-user devices (microcomputers or perhaps personal computers). 4. WRITE SHORT NOTES ON:

(a)Analog Computers: An analog computer is a form of computer that uses the continuously unpredictable, uncertain, changing aspects of physical phenomena just like electrical, mechanical, or hydraulic quantities to model the situation being solved. Analog pcs fed directly analog signals however usually do not suffer from quantization noise in contrast to their digital counterparts, consequently being restricted to analog noise. Analog computers were trusted in clinical and industrial applications in which digital pcs of the time weren't getting sufficient functionality. Analog personal computers can have a very wide range of complexity. (a) Digital Computers:

(b) Crossbreed Computers

10a Characteristics of Third Era Computers:

Utilization of integrated brake lines: The use of integrated circuits (Ics) replaced the transitors with the second-generation machines. The brake lines are imprinted and printed and a huge selection of electronic parts could be put on silicon routine chips less than...
