What is Computer Bus: The electrically conducting path along which data is transmitted inside any digital electronic device. A Computer bus consists of a set of parallel conductors, which may be conventional wires, copper tracks on a PRINTED CIRCUIT BOARD, or microscopic aluminum trails on the surface of a silicon chip. Each wire carries just one bit, so the number of wires determines the largest data WORD the bus can transmit: a bus with eight wires can carry only 8-bit data words, and hence defines the device as an 8-bit device.

A computer bus normally has a single word memory circuit called a LATCH attached to either end, which briefly stores the word being transmitted and ensures that each bit has settled to its intended state before its value is transmitted.

                                    NetBook

The concept of netbook is not so far from its portable design, but it is lighter and thinner, and limited storage than a laptop. Netbooks are like physical paper book; its design is just like a laptop. His name also reflects its main purpose: Net synonymous English Internet and book for "book", in short, the book for the Internet. The term netbook promoted by Intel.

Definition: A control unit (CU) (or controller, same thing) is a piece of hardware that manages the activities of peripherals (separate devices attached to the computer, such as monitors, hard drives, printers, etc.) Control units found on personal computers are usually contained on a single printed circuit board. The control unit acts as a sort of "go-between," executing transfers of information between the computer's memory and the peripheral. Although the CPU (central processing unit-the "big boss" in the computer) gives instructions to the controller, it is the control unit itself that performs the actual physical transfer of data.

Definition: A supercomputer is the fastest computer in the world that can process a significant amount of data very quickly. The computing Performance of a "supercomputer" is measured very high as compared to a general purpose computer. The computing Performance of a supercomputer is measured in FLOPS (that is floating-point operations per second) instead of MIPS. The supercomputer consists of tens of thousands of processors which can perform billions and trillions of calculations per second, or you can say that supercomputers can deliver up to nearly a hundred quadrillions of FLOPS.

The term Ultrabook, what do they really mean? The ultrabook is a new Intel-defined format. Basically, it is a new way of calling notebooks or laptops, to differentiate a little ocean of varieties available. Unlike netbooks that are smaller but also less powerful, ultrabooks offer virtually the same comfort as laptops.

Definition: Micro Computer is a small computer. Your personal computers are equivalent to the microcomputer. Mainframe and Mini Computer is ancestor of microcomputer. Integrated Circuit fabrication technology reduces the size of Mainframe and Minicomputer.
Technically, a microcomputer is a computer in which the CPU (central processing unit, the brains of the computer) is contained on one single chip, a microprocessor, input/output devices and storage (memory) unit. All these components are important for a proper working of microcomputer.

The Definition and meaning of mainframe has shifted from its original reference to the main housing, or frame, that contained the central processing unit (CPU) of the computer. In those days, all computers were big-like the size of a garage and the frame for the CPU might have been as big as a walk-in closet. Now mainframe refers to the kind of large computer that runs an entire corporation.

Definition: A minicomputer is also known as mini. It is a class of small computers that was introduced into the world in the mid-1960s. A minicomputer is a computer which has all the features of a large size computer, but its size is smaller than those. A minicomputer lies between the mainframe and the microcomputer because its size is smaller than the former one and larger than the latter one. A minicomputer is also called as a mid-range computer. Minicomputers are mainly multi-users systems where more than one user can work simultaneously. Mini computer examples: IBM’s AS/400e, Honeywell200, TI-990

What is 32-bit: 32-bit tells us that the number of bits that can be processed or transmitted. In another way, you can say that the number of bits that can be used for the single element in a data format.
32-bit is a type of CPU (Central Processing Unit) architecture that can transfer 32 bits of data per clock cycle or you can say that it is the amount of information that the CPU can process every time it performs an operation.

Definition: Analog computer is that computer, which is use to process continuously varying data. Everything we see and hear is change continuously. This changeable continuous stream of data is called analog data. Analog computer can be used in scientific and industrial applications such as measure the electrical current, frequency and resistance of capacitor, etc.
