Important Computer Hardware Interview Questions
What Is A Computer?
Computer is a programmable machine. It the integral part of everyday life.
What Are The Different Functions Of A Computer?
A computer does the following functions;
a) Accepting data
b) Processing Data
c) Storing Data
d) Displaying Data
b) Processing Data
c) Storing Data
d) Displaying Data
How A Minicomputer Different From A Mainframe?
Minicomputer is a midsized multiprocessing and multi user computer. It is also called mid-range server. But mainframes are huge computers, most commonly occupying entire rooms or floor. It is highly costly.
What Is Super Computer?
The fastest type of computer. Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations. For example, weather forecasting requires a supercomputer. Other uses of supercomputers include animated graphics, fluid dynamic calculations, nuclear energy research, and petroleum exploration.
Differentiate Input And Output Device?
Input devices are used for giving input to the computer. But output devices are used to get the result back from the computer. The examples of input devices are keyboard, mouse, scanner, digital camera atc…whereas output devices include monitor, printer, projector etc….
What Is A Storage Device? What Is The Common Classification?
Storage devices are used to store data in the computer. The different types of storage devices are:
a) Magnetic Devices.
b) Optical Devices.
c) Solid-State Storage Devices.
b) Optical Devices.
c) Solid-State Storage Devices.
What Do You Mean By A Processing Device? What Are The Various Types Of Processing Devices?
The main function of a computer is to process data. The various types of processing device in a computer are:
a) Microprocessor
b) Chipset
c) BIOS
b) Chipset
c) BIOS
Differentiates Serial And Parallel Port?
Serial port and parallel port are used for transferring data in/out of the computer. In serial port transmission only 1 bit is transmitted at a time. Most serial ports on personal computers conform to the RS-232C or RS-422 standards. A parallel interface for connecting an external device such as a printer.
On PCs, the parallel port uses a 25-pin connector (type DB-25) and is used to connect printers, computers and other devices that need relatively high bandwidth. It uses parallel transmission of data.
What Is An Interface?
These are the communication channel that enables your computer to exchange information with various devices.
What Is A Microprocessor?
The most important electronic component on the computer. It is a programmable logical device for processing data. In the world of personal computers, the terms MICROPROCESSOR and CPU are used interchangeably.
What Are The Factors Affecting The Speed Of The Microprocessor?
The following are the factors affecting the speed of the microprocessor.
a) Number of instructions build in the processor.
b) Bandwidth
c) Clock Speed
d) Number of transistors inside the processor
b) Bandwidth
c) Clock Speed
d) Number of transistors inside the processor
What The Difference Between Fsb And Bsb?
Front Side Bus. Another name for the system bus. The Front Side Bus connects the CPU to main memory. A microprocessor bus that connects the CPU to aLevel 2 cache is called Back Side Bus. Typically, a backside bus runs at a faster clock speed than the Front Side Bus.
What Is Packaging A Microprocessor? What Are The Different Packaging Available?
Packaging is the process of connecting a microprocessor with a computers motherboard.
The types of microprocessor packaging are:
a) PGA
b) SPGA
c) SECC
d) LGA
b) SPGA
c) SECC
d) LGA
What Is Lga ?
An LGA socket is the connection point for a central processing unit (CPU) to fit into a motherboard. The LGA stands for Land Grid Array.
What Is Cisc And Risc?
Reduced Instruction Set Computer (RISC) and Complex Instruction Set Computer (CISC) are two philosophies by which computer chips are designed. RISC became a popular technology buzzword in the 1990s, and many processors used in the enterprise business segment were RISC-based.
What Is Intel Pentium?
The Intel Pentium is a series of microprocessors first developed by the Intel Corporation. These types of processors have been found in many personal computers since 1993.
Any Difference Between Pentium Iii And Iv?
There have been a number of Pentium processor lines starting with the base Pentium in 1993.The of the recent Pentium entries are Pentium III and Pentium 4.
a) In a Pentium III processor, the bus speed is generally 133 MHz (although there were a few with 100 MHz). The lowest bus speed on a Pentium IV is 400 MHz, and there are versions with much higher speeds (topping at 1066 MHz for the “extreme edition”).
b) The Pentium 4s are smaller than the Pentium IIIs
c) Pentium III processors had (for the most part) about 512 KB of cache. Pentium 4 processors, on the other hand, start at 512 KB.
b) The Pentium 4s are smaller than the Pentium IIIs
c) Pentium III processors had (for the most part) about 512 KB of cache. Pentium 4 processors, on the other hand, start at 512 KB.
