Hard drive abbreviated as HDD “Hard Disk Drive” or HD, the drive is the computer’s primary storage media system that completely stores all information about the computer. The drive was initially launched on September 13, 1956 and includes a number of drive platters within air sealed housing.

The data is stored on the hard drive magnetically, so it stays on the drive even after the power supply is turned off. The two most common form factors for modern HDDs are 3.5-inch, for desktop computers, and 2.5-inch, primarily for laptops. HDDs are connected to systems by standard interface cables such as PATA (Parallel ATA), SATA (Serial ATA), USB or SAS (Serial attached SCSI) cables.


An input device is any hardware system that delivers information with no input devices, towards the computer, a computer might just be considered a screen system and never let customers to connect to it, similar to a Television.

The image is just a typical example of an input device and a Logitech trackball mouse.



Stands for “Liquid-Crystal Display”, LCD are a level display technology and flat screen screens. The LCD is accessible as an active matrix, dual scan, or passive-matrix display and made of two sheets of a flexible polarizing material with a layer of liquid crystal solution between the two.

Now LCD technology is being replaced by LED to enhance the performance and color screen of computers.


A number of networked computers which have been setup to deal with each person seeking or visiting information and each of them computer is called a node.

A number accounts for a variety of duties, For example, if a network connects a file server, five computers, and two printers, there are eight nodes on the network.

Each device on the network has a network address, such as a MAC address, which uniquely identifies each device.

A printer is an output device which provides result in the form of a hardcopy of this information and getting computer data. It very common output hardware device.

Models are among the used peripherals on computers and therefore are popular to produce photos, pictures, and text. For example laser, inkjet are types of printer.


Stands for “Small Computer System Interface”, SCSI is pronounced as “Scuzzy” and it is among the most often used interface for disk drives which was completed in 1982. Unlike competing requirements, SCSI is effective at helping sixteen devices with Wide SCSI, or seven products.

However, using the SCSI host adapter found on shoes and identification number 07 in the identification 00. This leaves the accessibility to six system connections.


A hardware device attached to the soundcard of a computer that outputs sounds produced from the computer. Speakers are transducers that convert electromagnetic effect into sound waves.

The speakers receive audio input from a device such as a computer or an audio receiver. This input is either in analog or digital form.


Instead referred to dummy terminal, as a diskless node, or dumb terminal, a diskless workstation is just a networked computer that delivers floppy disk drive access or no local drive space.

These devices possess network card, motherboard, a check, keyboard, and mouse.

This phrase may also be applied to explain any computer that’s a hard drive, but is starting and using programs in the community in the place of in the local hard drive.

This kind of computer is usually known as network computer or a hybrid computer.


Volume may also refer to how much space a three-dimensional thing takes up. However, in the always vague realm of computers, the word volume can also refer to a definite data storage device.

Some examples of volumes include dvd, hard disk usb etc.



ADF is an acronym of “Automatic Document Feeder” with the help of it several pages can be copied and scanned in copiers and scanners respectively in one time without inserting them individually in both devices.

A duplexing automatic document feeder or DADF scans both sides in one pass. The advantage of the DADF is faster speed for two-sided originals. RADFs and DADFs are rated in images per minute (IPM), the number of sides they can scan each minute.

This may depend upon the resolution being used (rather than the maximum resolution
It helps the user to complete the work easily without wasting of time.


CD-R stands for “Compact Disk Recordable” is a blank cd which is used to record and data. Once the data is recorded cannot be modified forever.

The data burned onto a CD-R disc is everlasting, denotation it can not be distorted or erased like the data on a hard drive.

Some drives use special techniques, such as Plextor’s GigaRec or Sanyo’s HD-BURN, to write more data onto a given disc; these techniques are inherently deviations from the Compact Disc (Red, Yellow, and/or Orange Book) standards, making the recorded discs proprietary-formatted and not fully compatible with standard CD players and drives.


Stands for “Dual in line Memory Module”, DIMM is just a circuit board that keeps memory chips. DIMMs have a 64bit route due to the Pentium Processor requirements.

Due to the new bit route, DIMMs could be mounted one at the same time, unlike SIMMs on the Pentium that will need two to be included.

while standard DIMMs have a 64-bit data path. Since Intel’s Pentium, many processors have a 64-bit bus width, requiring SIMMs installed in matched pairs in order to populate the data bus. The processor would then access the two SIMMs in parallel. DIMMs were introduced to eliminate this disadvantage.



DVR stands for “Digital Video Recorder” is a house digital camera like the VCR that allows customers to report common shows anytime to some computer drive. Why DVDs is ever more popular is the capability to get a person to report a common show watching them anytime as well as their simplicity of use.

Consumer digital video recorders ReplayTV and TiVo were launched at the 1999 Consumer Electronics Show in Las Vegas, Nevada.[2] Microsoft also demonstrated a unit with DVR capability, but this did not become available until the end of 1999 for full DVR features in Dish Network’s DISHplayer receivers.

TiVo shipped their first units on March 31, 1999. ReplayTV won the “Best of Show” award in the video category[3] with Netscape co-founder Marc Andreessen as an early investor and board member,[4] but TiVo was more successful commercially.


Hard Token means a cryptographic key located on the unique hardware device for example a PDA (personal digital assistant), mobile phone, smartcard, Flash drive, one time code system) instead of on the general purpose computer. Some may store cryptographic keys, such as a digital signature, or biometric data, such as fingerprint details. Some may also store passwords.

Some designs feature tamper resistant packaging, while others may include small keypads to allow entry of a PIN or a simple button to start a generating routine with some display capability to show a generated key number.

Special designs include a USB connector, RFID functions or Bluetooth wireless interface to enable transfer of a generated key number sequence to a client system. For example, a username and password or a fingerprint scan may be required along with the hard token to gain access to a secure system.


IC is a simple processor, monolithic integrated enterprise, or microchip, IC is quick for Integrated Circuit or Integrated Processor and was initially released like a principle by Geoffrey Dummer a British radar engineer on May 7, 1952 and later successfully produced by Jack Kilby and Robert Noyce and first confirmed September 12, 1958.

The IC is just a bundle containing paths, several tracks, transistors, along with other electronic parts all working to do perhaps a number of functions or a specific purpose.

Integrated circuits would be the blocks of computing devices.


Stands for “Light-Emitting Diode”, LED is a special semiconductor that illuminates when an electric charge passes through it. LEDs are normally green or reddish can be an array of other colors.

Modern advances in LED technology have completed it possible for LEDs to produce white light as well. LEDs are frequently used for indicator lights (such as power on/off lights) on electronic devices.


Non impact printer do no make noise while printing any document because they use latest technology in which pins are not involved to strike the papers.

For Example, Inkjet printers and laser printers are equally illustrations of the Non-impact printer. The speed of these printers is slow and cannot print more pages in a minute.

Alternatively known as the mind of the computer, processor, main processor, or microprocessor, the CPU (pronounced as D-P-U) was initially created at Intel using the aid of Ted Hoff within the early 1970’s and it is quick for Central Processing Unit.

The computer processor accounts for managing all directions it gets from application and equipment working on the COMPUTER.

It has two main parts ALU and CU to execute the data. Without processor computer cannot work it the same like human brain.



Stands for “Secure Digital” this card is among the more prevalent kinds of memory cards combined with technology. More than 400 manufacturers of digital equipment us the SD technology and over 8000 different versions, including cameras can mobile phones.

It’s considered the standard because of the extensive use. The SD card includes a known optimum storage capacity of 2GB (gigabytes), but 4GB versions do exist.

The 4GB versions were undue to restrictions & problems using the engineering at that potential.


A stand for “Static Random Access Memory”, It is computer memory that needs a continuing energy movement to be able to maintain information.

Though faster than DRAM, SRAM demands more energy and is a lot more costly; thus, it’s generally just utilized in video and cache card memory.

It does not need to refresh again and again due to high quality of performance.


Thunderbolt is an interface used for connecting peripheral devices to some computer-using an expansion bus.

It’s a serial interface that includes Display Port engineering and current COMPUTERI Express, permitting longer-distance of cheaper cables and knowledge exchange.

Intel, which owns the privileges for the technology developed Thunderbolt. Apple helped bring the technology to promote by including it within the current Mac Book Pro versions in February 2011


Stands for “video Random access Memory, and pronounced vee-ram. VRAM is unique-function storage utilized by video adapters. Unlike traditional Memory, two different devices can access VRAM .

This permits the RAMDAC to gain access to the VRAM for display changes in the same time the video processor provides new information. VRAM produces better graphics performance but is costly than normal Memory.



AGP Stands for “Accelerated Graphics Interface”. AGP can be an advanced port created for 3D accelerators and Movie cards.

AGP launched in August of 1997 and created by Intel. Accelerated graphics interface presents a passionate level-to-point route which allows immediate access the machine memory to the graphics controller.

Finally, AGP allows (optional in AGP 1.0 and 2.0, mandatory in AGP 3.0) sideband addressing, meaning that the address and data buses are separated so the address phase does not use the main address/data (AD) lines at all.

There are some proprietary systems incompatible with standard AGP; for example, Apple Power Macintosh computers with the Apple Display Connector (ADC) have an extra connector which delivers power to the attached display.


Stands for “Compact Disc Read Only Memory” is a device which is used to read out the data from storage devices such cd, DVD etc.

They are already built in computers during the manufacturing process to read and run the available data on the cd. A button on cd-rom is pressed to insert and eject the cd. Several formats are used for data stored on compact discs, known as the Rainbow Books.

The Yellow Book, published in 1988,[4] defines the specifications for CD-ROMs, standardized in 1989 as the ISO/IEC 10149 / ECMA-130 standard. The CD-ROM standard builds on top of the original Red Book CD-DA standard for CD audio. Other standards, such as the White Book for Video CDs, further define formats based on the CD-ROM specifications.


To store and keep information as a storage device is called disk drive. They are used to store data and records which can be used later according to need and requirement of the users.

Disk storage is now used in both computer storage and consumer electronic storage, e.g., audio CDs and video discs (standard DVD and Blu-ray).

Each drive operates by spinning a disk and reading data from it using a small component called a drive head. For example disk drive would be drive and the computer floppy disk drive.
