What are th compare all generations of computer?
No difference really, they still take 1's and 0's and make mathematical calculations corresponding to their instruction sets (CPU). What is DONE with that has changed dramatically tho, with every new generation, and that's about the only real difference...well besides the darn size thing.
Any more of an answer would be doing your test for you, and take far more room than this page offers.
1st generation computers used vacuum tubes. This generation spanned roughly 1940s to 1958. Today's generation uses very complicated integrated circuits. It started no earlier than the 1990s. A typical single IC from a modern computer contains several orders of magnitude more components than an entire 1st generation computer occupying an entire room, and runs at speeds unimaginable in the 1st generation.

What is the processor in a personal computer called?
CPU, which stands for Central Processing Unit. Intel is probably the worlds largest producer of CPUs, which are now used in both PCs and Apple Mac computers.
The term CPU is also sometimes used to refer to the whole computer case containing the CPU and other components.
Why does a supercomputer require and air conditioned room?
A supercomputer generates a lot of heat, so it needs air conditioning to compensate, otherwise it would overheat the room and burn itself up.
The Commodore 64 is the best-selling single personal computer model of all time. Released in August 1982 by Commodore Business Machines, the Commodore 64 is commonly referred to as the C64 and occasionally known as CBM 64 (its model designation) or C-64. Introduced by Commodore Business Machines in August 1982 at a price of US$595 (then later reduced to US$200 in late 1983), it offered 64 kilobytes of RAM with sound and graphics performance that were superior to IBM-compatible computers of that time. During the Commodore 64's lifetime (between 1982 and 1994), sales totaled around 17 million units.

what are the different classifications of computers according to their purpose?
- Microcomputers - Includes your desktop,tablet,smartphone and laptop
- Minicomputers - computers having power scale less than that of Mainframes (Vax , PDP)
- Mainframe computers - also called the "Big Iron" is mainly used in airports , banks and government institutes ( DEC 10 , NEC 610 )
- Supercomputers- made for massive calculation/processing ( IBM Roadrunner , CX1 )
What is the origin of the expression neat as a pin?
In the early 19th. Century, the development of mass production guaranteed a uniformly high quality and finish of consumer products. Formerly hand-made and thus frequently irregular, now, pins were consistently well made and finished.
Classification of computer according to its size?
According to size
• Supercomputers
• Mainframe Computers
• Minicomputers
• Workstations
• Microcomputers, or Personal Computers
Supercomputers : are widely used in scientific applications such as aerodynamic design simulation, processing of geological data.
• Supercomputers are the most powerful computers. They are used for problems requiring complex calculations.
• Because of their size and expense, supercomputers are relatively rare.
• Supercomputers are used by universities, government agencies, and large businesses.
Mainframe Computers: are usually slower, less powerful and less expensive than supercomputers. A technique that allows many people at terminals, to access the same computer at one time is called time sharing. Mainframes are used by banks and many business to update inventory etc.
• Mainframe computers can support hundreds or thousands of users, handling massive amounts of input, output, and storage.
• Mainframe computers are used in large organizations where many users need access to shared data and programs.
• Mainframes are also used as e-commerce servers, handling transactions over the Internet.
Minicomputers: are smaller than mainframe, general purpose computers, and give computing power without adding the prohibitive expenses associated with larger systems. It is generally easier to use.
• Minicomputers usually have multiple terminals.
• Minicomputers may be used as network servers and Internet servers.
Workstations
• Workstations are powerful single-user computers.
• Workstations are used for tasks that require a great deal of number-crunching power, such as product design and computer animation.
• Workstations are often used as network and Internet servers.
Microcomputers, or Personal Computers : is the smallest, least expensive of all the computers. Micro computers have smallest memory and less power, are physically smaller and permit fewer peripherals to be attached.
• Microcomputers are more commonly known as personal computers. The term "PC" is applied to IBM-PCs or compatible computers.
• Desktop computers are the most common type of PC.
• Notebook (laptop) computers are used by people who need the power of a desktop system, but also portability.
• Handheld PCs (such as PDAs) lack the power of a desktop or notebook PC, but offer features for users who need limited functions and small size.

They can also be classified in different ways like classification of computers by size. v Super computer
Super computers can process huge amounts of data, The biggest in size, the most expensive in price than any other is classified and known as super computer. It can process trillions of instructions in seconds. This computer is not used as a PC in a home neither by a student in a college. Governments specially use this type of computer for their different calculations and heavy jobs. Different industries also use this huge computer for designing their products. In most of the Hollywoods movies it is used for animation purposes. This kind of computer is also helpful for forecasting weather reports worldwide. v Mainframes
Another giant in computers after the super computer is Mainframe, which can also process millions of instructions per second and is capable of accessing billions of data. This computer is commonly used in big hospitals, air line reservation companies, and many other huge companies prefer mainframe because of its capability of retrieving data on a huge basis. This is normally to expensive and out of reach from a salary-based person who wants a computer for his home. This kind of computer can cost thousands of dollars. v Minicomputer
This computer is next in line but offers less than mainframe in work and performance. These are the computers which are mostly preferred by the small type of business personals, colleges, etc. v Personal computers
Almost all the computer users are familiar with the personal computers. They normally know what the personal computer is and what are its functions. This is the computer mostly preferred by the home users. These computers are lesser in cost than the computers given above and also, small in size; they are also called PCs in short for Personal computers. This computer is small in size and you can easily arrange it to fit in your single bedroom with its all accommodation. Today this is thought to be the most popular computer in all. v Notebook computers
Having a small size and low weight the notebook is easy to carry to anywhere. A student can take it with him/her to his/her school in his/her bag with his/her book. This is easy to carry around and preferred by students and business people to meet their assignments and other necessary tasks. The approach of this computer is also the same as the Personal computer. It can store the same amount of data and having a memory of the same size as that of a personal computer. One can say that it is the replacement of personal desktop computer.
Who invented the first tandy color computer?
The first 'Tandy Color Computer' was referred to as the 'Radio Shack Color Computer'. It wasn't until near the end of the second version of the color computer (There were three in total) that the name was changed to the 'Tandy Color Computer 2'. The first version, as with the others, was developed by the Tandy Corporation (parent company of Radio Shack). The original color computer used the Motorola MC6809E microprocessor as the primary CPU, MC6847 VDG (Video Display Chip), The MC6883 SAM (Synchronous Address Multiplexer), and two Peripheral Interface Adapter chips (for Input/Output). That, plus RAM and ROM comprised the heart of the machine. The original machine came with 4k of RAM and 8k of ROM (color basic). Ultimately, Tandy released an extension to color basic (extended color basic), bringing the ROM to 16k, and RAM upgrades to 16, 32, and ultimately 64k. The original color computer had the standard 'Tandy Gray' color and a 'calulator style' 'chicklet' keyboard. The final revisions of the first color computer did convert to a white case. The next version of the color computer was functionally identical to the first in nearly every respect, and had an improved, but still flat keyboard, which was eventually changed to a full travel keyboard. The internal workings were improved, but retained the same basic chip layout for CPU, Video, SAM, and PIA. The last computer in the line was the Tandy color computer 3, which added 4 keyboard keys (control, alt, F1, and F2), and much of the internal workings were condensed to a single chip. The Video and Address chips were condensed to a single Chip (GIME)or 65424 Chip. This chip emulated all supported modes of the original machines, but left out some upsupported, (but non the less sometimes used) 'semi graphics' modes. It did however increase the resolution and color set over the older systems. By the end of life cycle of the color computer, it had a huge following which lives on today in a small, but active vintage community and emulators, but by the early 90's, it was clear that the majority of the market was going the PC compatilble route, and the color computer 3 was discontinued.
