For Example, computer memory (Memory), employs solid state media. Memory includes microchips that store data on non moving elements, offering for quick access of this information.

The transistor is recognized as to become the initial popular solid state system and it is still getting used in just about all electronics today.


Stands for “Thin Film Transistor” (TFT) and active matrix LCD (AMLCD), an active matrix screen is just a liquid crystal display (LCD) first launched using the IBM ThinkPad in 1992.

With active matrix shows, each pixel is managed by someone to four transistors that may create the display faster, better, more vibrant than passive-matrix, and effective at being seen at different perspectives.

As a result of this enhanced technology, active matrix displays tend to be more costly than their passive matrix counterparts.


Means “Video Graphics Array” It is the standard monitor or display interface used in computer system. The VGA standard granted to get a screen quality of 640×480 pixels and was produced by IBM in 1987. Since then, several changes of the conventional have been released.

The most typical is Very VGA (SVGA) that allows for promises more than 640×480, for example 800×600 or 1024×768. A typical VGA connection has 15 pins and it is designed like a trapezoid.

Since the source code of an open source program can be customized by anyone, it makes logic that the software is also free to download and use. They are free available to general public and no technical support included with the software.

Users get their answers depending on web forum and discussions on the internet which is part of very helpful resources.

Linux operating system, Mozilla Firefox internet browser is project of open source. Moreover open source programs are cost effective can be very helpful to run many program on the computer system.


Access Point may be computer software or a hardware device is used to connect to WLAN (Wired Local Area Network) for users of the wireless device. In a WAP (Wireless Access Point)setting up a computer network in a business, home or school often required running many cables through walls and ceilings in order to deliver network access to all of the network-enabled devices in the building.
With the creation of the wireless access point, network users are now able to add devices that access the network with few or no cables.

Access points ranges from 50 feet in diameter to 1,000 feet with amplification along with the basic goals to expand the internet access for the users.


While talking about a computer, the bus called information bus, the handle bus, or nearby bus is just a data link between several devices. It is used to interconnect the computers and its other parts for communication.


For example, a coach allows a PC processor to speak using perhaps a movie card or the memory to speak using the storage.


Computer systems generally consist of three main parts: the central processing unit (CPU) that processes data, memory that holds the programs and data to be processed, and I/O (input/output) devices as peripherals that communicate with the outside world.


Stands for “Double Data Rate2”, DDR2 may be the second-generation of DDR memory that started being offered in 2003 that’s been replaced by DDR3. DDR2 provides a better bandwidth potential, is able to running at greater rates of 400 MHz and greater, works in lower-power consumption, and produces less heat.

Due to the differences between DDR2 and DDR, DDR2 memory segments are not compatible with DDR slots.

Since the DDR2 internal clock runs at half the DDR external clock rate, DDR2 memory operating at the same external data bus clock rate as DDR results in DDR2 being able to provide the same bandwidth but with higher latency.


Stands for “Digital Versatile Disc-Recordable”, DVDR is comparable to the concept behind cd r, where it is passing through is able or saving after it’s been developed once to some disc after which read-many times.

DVDR is an accepted standard by DVD Community as well as the devices can handle saving to DVDR discs, also called DVD-5 DVD and -10 discs.


An optical reader is just a hardware input system which allows a person to consider a picture or text and transform it right into a digital document, enabling the computer show or to see the scanned object.

A reader could be attached to a PC using Parallel, Firewire, Hardware, or perhaps a SCSI interface.


An impact printer is a course of models before striking the site that features by producing real connection with an ink ribbon.

They produce noise while printing any kind of document. Dot matrix, Daisy wheel and point are types of impact printers. They make noise while printing any documents.


Laptop is like a notebook, a laptop is a portable computer that with the same skills as a desktop computer, but is not large enough for easy freedom.

Portable computers run off batteries or AC power, like NiCad or NiMH packs, for several hours. Laptop screen is LCD stands for liquid crystal display.

They are expensive than simple personal computers. They have touch screen pad also known as sensitive pad for moving the objects with the fingers of hands.

Stands for “Network Access Server”, NAS can also be called a critical server and it is a network or PC system that conveys you with service or another computer.

It stored internal and external hard drive data in a organized way. By using NAS, computers can store and access data using a centralized storage location.

For Example, when you call into connect with the Web; you are calling into a NAS.


Stands for “Personal Computer Memory Card International Association”, PCMCIA is a business association created in 1989 that’s accountable for the continuing development of the PCMCIA standard.

PCMCIA cards are hardware interfaces which are somewhat larger than a typical charge card that allow extra performance for other portable devices and laptops.


An optical reader is an input hardware system which allows a person to consider a picture or text and transform it right into a digital document, enabling the computer show or to see the scanned object.

A reader could be attached to a COMPUTER using Parallel, Firewire, Hardware, or perhaps a SCSI interface.


An audio card or as an audio board and provides input or output sound ability and integrated enterprise or an extension card that delivers a COMPUTER using the capability to create sounds that is noticed from the person both over headphones or speakers.


Thermistors are sensitive resistors whose primary purpose would be to display an exact, expected and sizable change in electric resistance when put through a similar change in body temperature. Thermistors are commonly used in computers to monitor the ambient temperature of internal components.

For example, thermistors used to record the temperature near the main memory, central processing unit and the power supply.

These thermistors are usually integrated into the computer’s motherboard. The actual temperature of components such as the CPU and memory modules is commonly measured by a diode that is integrated into the chip.

On the other hand if the thermistors testimony a dangerously high temperature, the computer may shut down to avoid overheating and damaging the hardware.


Instead referred to perhaps a movie control, graphics card, video adapter, video table, or as a display adapter.

A video card can be an internal circuit board which allows a screen system like a check to show pictures in the computer.

Active Matrix display was introduced in 1992 by IBM with the ThinkPad. It has the liquid crystal display in which (TFT) Thin Film Transistor control the pixel of display and enhances. The Macintosh Portable (1989) was perhaps the first consumer laptop to employ an active matrix panel.

Today, virtually all TVs, computer monitors and smart phone screens that use LCDor OLED technology employ active matrix technology.

The screen by making it more faster, attractive colorful and also brighter which helpful to watch the screen from different angles but on the other hand such display consume more power than passive-matrix.


A cable modem is just an electronic product that changes the analog signal-to an electronic sign with the objective of allowing a broadband net connection and permit your PC to speak having an Online Sites Supplier over a wire connection.

A cable modem functions by linking a coaxial wire for that ISP towards the back of the cable computer along with a Cat5 (Ethernet) wire in the device to some pc or perhaps a community modem if you like to talk about Your Online link between multiple computers.

Cable offers a significant speed increase in Internet performance when compared to a dial-up connection and is one of the fastest broadband solutions. Comcast and Time Warner are examples of cable Internet providers in the United States.


Stands for “Double Data Rate3”, form three, DDR3 may be the heir of DDR and DDR2 memory and it is a kind of storage (Memory) to get a computer.

DDR3 has bus clock rate of 400 MHz as much as 1066 MHz, and memory chips array in dimensions from 1 GB to 24 GB. DDR 3 memory chips are almost 30% more effective in energy use than its predecessor, getting a 1.5V supply voltage (DDR2 – 1.8V).

The DDR3 standard permits DRAM chip capacities of up to 8 gibibits, and up to 4 ranks of 64 bits each for a total maximum of 16 GiB per DDR3 DIMM. Because of a hardware limitation not fixed until Ivy Bridge-E in 2013, most older Intel CPUs only support up to 4 gibibit chips for 8 GiB DIMMs (Intel’s Core 2 DDR3 chipsets only support up to 2 gibibits). All AMD CPUs correctly support the full spec for 16GiB DDR3 DIMMs.


DVDRAM stands for “Digital Versatile Disc-–Random Access Memory” is a disk specification introduced in 1996 from the DVD forum which identifies rewritable DVDRAM media as well as the proper DVD writers.

DVD RAM media have already been utilized in cameras in addition to computers and private video recorders since 1998.
The on-disc structure of DVD-RAM is closely related to hard disk and floppy disk technology, as it stores data in concentric tracks.

DVD-RAMs can be accessed just like a hard or floppy disk and usually without any special software. DVD-RWs and DVD+RWs, on the other hand, store data in one long spiral track and require special packet reading/writing software to read and write data discs. Like magneto-optical (MO) technologies.


A floppy diskette was initially produced in 1967 by IBM to assist have an alternate to purchasing hard disks which were extremely expensive at that time and weren’t regarded as anything to be utilized with a typical computer.

It is coated with iron oxide and stores data magnetically, just like a secondary storage like hard disk.
