Shopping For Parts

First of, you’ll need a place to do your shopping. If you don’t have any computer stores around you locally (like me) then you’ll have to go online. Which is no problem! Big selections, low prices, and quality merchandise if you know where to look! This is the one time I will advise against buying on Ebay. If you are new to computers you may end up getting lots of parts that are of no use to you due to seller’s mis-representing. Most sellers have a policy about checking compatibility – So you’ll be stuck with the parts. My favorite online source for PC parts is Directron. They have a massive selection, low prices, reasonable shipping, and i’ve never been dissapointed with them. There are lots of other good places like New Egg, but personally i’ve not needed to buy anywhere else.

Motherboards

—————-

The motherboard is the beating heart of your PC. All the other pieces plug into it, and are given life. When you purchase a motherboard you need to make sure it will work with all your other parts. When looking to make a purchase ask yourself the following questions.

* Will this board support the processor I want?

* Does it support single or dual channel memory? Does it have enough slots?

* How many PCI slots will I need?

* Does it support IDE, SATA, or both?

* What size is it?

By browsing the long list of specifications; you can thumb through it until you have answered all these questions. We’ll take this MSI motherboard for an example..

Processors: Supports 64-bit AMD Athlon 64 processor (Socket 754). Supports 2800+, 3000+, 3200+, 3400+, 3700+. Supports Sempron 2600+, 2800+, 3000+, 3100+, 3300+.

“This board supports AMD processors – If you want to use an Intel processor you’ll need to pick a board that is made for those. The numbers are the power of the processor – it will support a 2800 – 3700 mhz Athlon 64 or 2600 – 3300 mhz Sempron. Make sure you buy the correct socket else you’ll find yourself with the wrong connections! In the case of our example we’ll need to get a 754.”

Memory: Supports two 184-pin DDR SDRAMs up to 2GB memory size. Supports DDR400*/DDR333/DDR266 DDR SDRAM.

“This board has two RAM (Random Access Memory) slots. It will support up to 2GB of memory of the DDR400, DDR333. and DDR266 varities. If you don’t buy the correct sticks they will not fit in the slots.”

On-Board IDE:An IDE controller on the VT8237R chipset provides IDE HDD/CD-ROM with PIO, Bus Master and Ultra DMA 66/100/133 operation modes. It can connect 4 Ultra ATA drives. Serial ATA/150 controller integrated in VT8237R: Up to 150MB/s transfer speed. Can connect up to 2 Serial ATA drives. Support RAID 0, RAID 1. Audio: 6 Channel software audio codec VIA VT1617A. Compliance with AC97′ v2.3 Spec. Meet PC2001 audio performance requirement.

“IDE are the slots that connect things like your Hard drives, CD Rom drives, ect. The board in this example will allow you to use 4 ATA (IDE) devices. (Two ribbon cables to the board itself, and two devices to each cable.) This board also supports two SATA devices if you want to you them; or upgrade in the future.

On-Board Peripherals: 1 floppy port supports 1 FDD with 360K, 720K, 1.2M, 1.44M and 2.88Mbytes. 2 serial ports (COM2 supported by pin-out). 1 VGA port. 1 parallel port supports SPP/EPP/ECP mode. 8 USB 2.0 ports (Rear x 4 / Front x 4). 3 audio ports in vertical (Line-out, Line-in, MIC). 1 RJ-45 jack. 1 IrDA connector for SIR/ASKIR/HPSIR.

” This board also has..

* Support for one floppy drive.

* 2 Com serial Ports

* 1 VGA port

* 1 Parallel port

* 8 USB ports (4 in the back of the PC and 4 in the front)

* 3 Audio ports (Line out, Line in, and a Mic)

* 1 RJ45 Jack (Telephone line or similar input)

* IrDA Jack (Infared Data Association)

How much you want to spend on a motherboard is up to you. If it has everything you want and looks solid then go for it. My main board cost about $80, had everything I need, and has so far treated me very well. I’ve got support for SATA, and four RAM slots so I can upgrade later on if I decide I want to.

This particular board is a mATX (Micro ATX) size component, and so we’ll need to make sure it will fit in the case we purchase. Else the mounting, connectors, ect. may be off.

Processors

The processor does just what it says – it processes your commands. The better the CPU then the faster your computer will be able to issue commands. Most people do not need a super high end processor for their everyday tasks.

Whether you want to go with Intel or AMD is really a matter of preference. You can listen to processor fights until your blue in the face, but I guess it’s just something you have to try for yourself. Personally, I’m an AMD user. So, we’ll use one of those for our example.

AMD Sempron 2800+

“Specifications: Processor: AMD Sempron. Model: 2800+. Core: Palermo. Ordering P/N (PIB): SDA2800BXBOX. Operating Mode: 32/64. Stepping: E6. Frequency: 1600Mhz. HT Speed: 1600. Voltage: 1.40V. Max Temp: 69oC. Thermal Power: 62W. L1 Cache: 128KB. L2 Cache: 256KB. CMOS Technology: 90nm SOI. Socket: Socket 754.”

From the description we can gather the information we need!

* We know our motherboard supports AMD. So check!

* We know it will support a processor with 2800 mhz of power. Check!

* We know our motherboard is socket 754 just like this processor! Check!

Alright, this processor is compatible! If you want to use a more or less powerful processor go ahead, and browse; Just compare the specs, and make sure you’re still compatible. Most processors come with the heatsink, fan, ect. so you shouldn’t have to worry about that.

Hard drive

Most of the work for this piece is based on how demanding of a user you are, and not compatibility. We’ll use this Seagate Barracuda for our example this time around.

Specifications: Model Number: ST3160815A. Interface: Ultra ATA/100. Cache: 8 MBytes. Capacity: 160 GB. Areal density (avg): 101 Gbits/inch2. Guaranteed Sectors: 312,581,808. Spindle Speed: 7,200 rpm. Average latency: 4.16 msec. Random read seek time: Random write seek time

—————-

Maximum interface transfer rate: 100 Mbytes/sec. PHYSICAL: Height (max): 19.99 mm (0.787 inches). Width (max): 101.6 mm (4.010 inches). Length (max): 146.99 mm (5.787 inches).

“This tells you some random information about the computer. The important information that we really need at this point…

* Interface: Ultra ATA(IDE) – If you didn’t pick a board with SATA then you’ll need this type of drive. IDE are older, and not as fast as SATA drives, but they will save you cash.

* Cache: 8MB – This means you can store 8MB worth of data for fast retrieving. Saves you time for things you use a lot basically.

* Spindle Speed: 7200RPM – This is how fast your drive will spin – The higher this number is the faster your drive will operate, and the faster your computer can fetch data.

* Capacity: 160 Gb – The most important bit of information! How much space we have to take up! Personally I’m very needy in this department I have a 400GB drive, and still want to upgrade. If you have lots of movies, music, games, and files opt for a bigger drive.

This is a standard 3.5 inch drive so the actual dimensions aren’t really important. Unless you are custom building a case then you don’t really need to measure anything like that since cases are build to support this universal size desktop drive. “

Memory (RAM)

RAM or Random Access Memory is what your computer uses to run applications. The more things you have going at once the more memory your computer is going to need to handle these commands. My computer runs 24 hours a day, and I have lots of idling programs; my 2GB of RAM is still not enough for me.

Let’s take a look at this Kingston 512MB stick.

Specifications: Model number: KVR333X64C25/512. 512MB 333MHZ 184PIN DDR Memory, No-ECC. Higher performance over mainstream PC100 or PC133 memory. Up to 2.1 GB/sec of peak bandwidth using PC2700 DIMMs (with DDR333 memory chips). JEDEC Standard. 184 pin DIMM, non-ECC. DIMM Lead pitch: 1.27 mm. 2.5 Volts. SSTL-2 I/O Interface. CAS Latencies: 2.5. SPD Support.

“From this description we can see that our RAM is..

* 184 pin – Just what our mother board needs.

* DDR333 (333 mhz) – Which is compatible with our main board as well.

* 512 MB – It’s fast approaching where this is not enough memory. If you want to run Windows Vista you should opt for 1 GB bare minimum. If you are heavy on applications then I’d go for more if you can afford it.

Case

A case is a lot of preference, but make sure you have parts that will fit inside it. If you bought a normal size board then don’t get yourself a micro sized case. This case will fit a standard or a micro ATX sized motherboard.

You can build anything from a tiny tabletop PC, to a full size floor server rack. You’ll have to read the description on anything you look at since some come with more than others. The one we’re looking at here comes with a 450 watt power supply. Keep in mind that anything you plug into your computer uses power, and you need one strong enough to handle it. Basic rule of thumb.. the more expensive (higher end) your parts.. the more power they will suck up. If you want a giant graphics card that takes up the whole case; don’t skimp on your power supply unit. ; )

Congrats! You’ve got all the important parts for your new computer! I didn’t highlight anything like CD/DVD drives since they shouldn’t be that tricky. With the information you’ve learned about the rest of the components that should be easy for you. : )

Happy Building.

DIY

There is a popular misconception that the quad core computer runs four times faster than the single processor computers. It does work, but for programs that are designed to perform on quad core computer. The codes written in those programs allow the processor to accomplish four different tasks simultaneously. Games such as Gears of War or Crysis which require multiple tasks like audio, physics benefit or AI to run simultaneously can be played through the multi-threading processors of quad core computer.

Performance wise quad core computers are faster in multitasking and parallel programming. For instance, multiple virtual machines can be run with four processors. Hardware virtualization, high-end video game playing provision, video and photo editing, audio transcoding, data folding, 3D rendering, voice recognition facility, the options are so many to choose from in quad core computers. You can run virtual studio on XP, work on Photoshop projects on core OSX install or do any other programs in lunux distro. You can also run XP virtual machine on top of XP. You will be able to run the maximum amount of virtual machines that ESX 3 is capable of running. However the number of Virtual machines you run depends on the memory space of your quad core computer.

While talking about quad core computers, it is worth discussing about certain models of the quad core family. The Kentsfield is the first quad core desktops range from Intel. Its High performance model was Core 2 Extreme QX6700 and mainstream brand was named as Core 2 Quad Q6600. Currently Intel has brought two other models: the Core 2 Extreme QX6850 and the Core 2 Quad Q6700. Of these two, the Core 2 Quad Q6700 is just a modification from the Core 2 Extreme QX6700 adorned with a locked core multiplier.

Actually the Core 2 Q series processor of Intel is nothing but combination of two completely distinguishable Core 2 Duos packaged into a single-socket CPU. The L1 and L2 caches are different to the two individual Core 2 sets. Front side bus architecture is used to communicate with a unit of external memory controller of the north bridge. The initial Core 2 Q6700 shows an effective 1066MHz FSB clock speed with a bandwidth of 8.5GB/sec and the Core 2 Extreme QX6850 can go up to 1333MHz having bandwidth of about 10.7GB/sec.

Having said about the things that you can do on a quad core computer, the question that is being currently debated on is whether these quad core computers are a real need for this hour. For example, same performance and speed can be achieved with a dual-core CPU of Core 2 E6850 as with the Core 2 Extreme QX6850. So why you any user opt for quad core series which are expensive than the Core 2 computers? It is a fact that for general purpose use, today, Dual core or Core 2 is best economical option. Actually quad core computers were not designed for general users. It is for high end users who want to use complex algorithm programs, run parallel programming, multithreading as well as multitasking simultaneously.

However, with the advent of more complex coding programming, quad core computer is expected to be in demand in near future. In fact, computer manufacturers are positive about a significant growth of quad core computer users with in a year or two.

Some still hold the opinion that graphics and art is a mind thing and one cannot become a graphics artist just by tweaking some shots in a computer. Creativity may still be elusive but there is little doubt that computer generated imagery and graphics have taken art to a new level. With the availability of new and better graphics tools an artist has more time to do things which he does best ……creating . It used to be domain of Mac’s, high end graphics workstations with the whiz kids hunched on its big impressive screen. But soon a slew of PC based graphics suites hit the market, turning every kid into a master craftsman. Adobe Photoshop may be considered to be a pioneer in this field. Corel’s Photopaint and Paint Shop Pro were and are being used widely even today. Windows based graphics software has made computer graphics accessible to the common man. With the advent of digital cameras, need for enhancing and improving family photos has lead to phenomenal growth of home grown studios. The pace has quickened with cameras mounted on mobile phones. The number of formats for graphics files has also increased with the times. Starting with the humble bit map file, bmp other popular formats are JPEG, TIFF, GIF and TARGA (.tga).

Adobe Photoshop

The field of computer graphics would not be complete without the mention of Adobe Photoshop. In fact, it can be considered as the Microsoft windows of the graphics world. The Photoshop tools make retouching, manipulation and color correction possible within a few minutes as compared to many days used by professional photographers using traditional tools. Photoshop uses its own native format .psd for storing files. The layer information can be preserved in this format, permitting the user to effect changes at a later date. However the native format .psd gives rise to large and heavy files which are rather difficult to transfer to other computers. Photoshop can also work with several other graphics file formats like BMP, JPEG, and Gif etc. It is also capable of importing vector graphics. In the latest version, it is also possible to work on several digital camera formats making it easy for home users to manipulate digital images.

Along with several other Adobe software, Photoshop can be used to create images not only for the print media but also for the internet, animation and motion pictures.

An important feature of Photoshop is the plug-ins. With plug-ins the capability of Photoshop is extended phenomenally. In fact, a sub culture or mini world has developed under the umbrella of plug-ins. Effects such as grain, lens flare, degauss etc. are quite popular. Color correction and manipulation is an important feature of Photoshop, lending magic to real world images.

Adobe Photoshop software is a pioneer in the field of computer graphics. It is moderately priced and is suitable for manipulating high resolution graphics. It can convert into a variety of graphics formats which are suited both for the print as well as web-sites.

Before Recording

If you have never recorded audio on a computer you may find that there are several easy ways to do so. Before attempting to record though, you will want to make sure you have a suitable microphone. These can range from a $10 computer microphone, a $1000 studio microphone, to one built in to your laptop. All these will work but the only differences will be audio quality, ranging from compression levels to audio pickup sensitivity.

Basic Recorders

The easiest and quickest way to record with any Microsoft Windows system is to use ‘Sound Recorder’ located within the start menu in Accessories. The only limitations are that recordings from Windows Sound Recorder are limited to time and one track. For more advanced recording you will probably want to use a "multitrack" software such as Mixcraft, Cubase, or Cakewalk.

Before Recording

Before using any software you will want to make sure your microphone is plugged in properly and that the correct drivers are installed if they are needed. Some hardware is "Plug and Play" meaning that it requires no driver installation. You can check on your computers audio input and output by going to Start, Control Panel, and Sound. If you find that you have no microphone input or output drivers you may need to search on the internet for your computers hardware sound device drivers. You can do this from any search engine.

Using Multitrack Recorders

If you are wanting to record audio with multiple tracks, such as, recording your voice to background music. The best way is to use multitrack software. For a simple recording of the previous example, you would add your background music to a track, "arm" another track for your voice and then record. Before recording you will want to make sure that the track you armed has the correct microphone settings.

Saving to .WAV, .WMA, or MP3 Format

To save your recording as a .wav, .wma, or .mp3 you will need to mixdown or export the audio to a media file. When selecting which type of file you want to save it as you will want to factor in file size to audio quality and format. .WAV files are particularly large files that take up a lot of harddrive space and might not be formatted to the specifications of audio (MP3 players) or websites. While most MP3 players and websites accept .WMA and .MP3 format. Also be aware of the various bitrates of your audio export.

Here are the basic interview questions for the network administrators, system administrators and IT manager posts. These questions provide the basic information about the network communication technology, network topologies, network troubleshooting techniques, network devices and the basic overview of the LAN/WAN communication model.

What is DHCP?

DHCP stands for Dynamic Host Configuration Technology. The basic purpose of the DHCP is to assign the IP addresses and the other network configuration such as DNS, Gateway and other network settings to the client computers. DHCP reduces the administrative task of manually assigning the IP addresses to the large number of the computers in a network.

What is DNS and how it works?
/>

DNS stands for Domain name system and it translates (converts) the host name into the IP address and IP address into to the host name. Every domain and the computer on the internet is assigned a unique IP address. The communication on the internet and in the network is based on the IP addresses. IP addresses are in this format 10.1.1.100, 220.12.1.22.3, 1.1.1.1 etc. IP addresses can’t be remembered but the host names (e.g. www.networktutorials.info, xyz.com, abc.com) are easy to remember instead of their IP addresses.

What is a Firewall?

Firewall is a protective boundary for a network and it prevents the unauthorized access to a network. Most of the Windows operating system such as Windows XP Professional has built-in firewall utilities. There are the large number of the third party firewall software and the basic purpose of all the firewall software and hardware is same i.e. to block the unauthorized user access to a network.

What is WAN?

WAN stands for wide area network and it covers the broader geographical area. Basically there are three types of a computer network LAN (Local Area Network), MAN (Metropolitan Area Network) and WAN (Wide Area Network). The communication in a WAN is based on the Routers. A WAN network can cover a city, country or continents.

Define VOIP Communication Technology

VOIP stands for Voice over IP and this technology is used for transmitted the voice over the IP based long distance network to make phone calls. VOIP phone calls are very cheap and a large number of the corporate offices and home users are using VOIP technology to make long distance phone calls.

What is Wi Max Technology?

Wi Max is a wireless broadband technology and it is a advance shape of the Wi Fi (which was a base band technology). Wi Max supports data, video and audio communication at the same time at a very high speed up to 70 Mbps.

Define Network Gateway

Network Gateway can be software or a hardware. A gateway is usually a joining point in a network i.e. it connects two networks. A computer with two LAN cards can act as a gateway.

What is a Router?

A router routes the traffic to its destination based on the source and destination IP addresses, which are placed in the routing software known as routing table.

How Fiber Optic Cable Works

Fiber optics provides the fastest communication medium for data and voice. Data can travel at the speed of light through the fiber optic cables. ISPs and corporate offices are usually connected with each other with the fiber optic cables to provide high speed connectivity.

What is File Server?

A file server is a computer in a network that authenticates the user access in a network such as Windows 2000/2003 Servers.

Define Seven Layers of OSI Model

There are seven layers of the OSI model. The basic purpose of these layers is to understand the communication system and data transmission steps. The seven layers are Application, Presentation, Session, Transport, Network, Data Link and Physical. You can remember the name of these layers by this phrase. “All people seems to need data processing”.

Define GSM Technology

GSM is a short range wireless technology and is usually used in the mobile phones, hand help devices, MP3 players, Laptops, computers and in cars.

One of the grounds on which buying and selling a WoW account becomes more popular as we speak is the possibility to relocate characters to various realms. Even though there are a number of limitations such as not finding it possible to make the transfer from normal to PvP realms, one of the advantages is the possibility to modify your name when progressing to the new realm.

In addition, you can transfer the character to a new WoW account, as long as you tag along a number of guiding principles. This will put off the preceding World of Warcraft account owner from the attempt of reclaiming the account. The guiding principles we were mentioning concern the matter of WoW character transfers.

In this respect, transfers from one WoW account to another are only permissible between accounts where the subscriber is the same individual. Generally, no sustaining goes to the relocation of WoW characters between friends, guild mates, or family parts. For this purpose, to perform an account-to-account reassignment, the official conditions stipulate that you should reply to the secret question allotted for the destination WoW account. In addition, the last names on both accounts must be the same.

Lastly, when you consider some of the available accounts of World of Warcraft for sale, you should keep in mind that power-leveled accounts have a propensity for displaying inferior quality equipment as compared to pre-owned WoW accounts. Even though there is a minor price variation, the complete assurance is likely to replace such a disadvantage quite successfully.

Accounts of World of Warcraft for sale are a recurrent practice in the wide area of this game, even though Blizzard does not support the practice. However, with a well-equipped WoW character, you can obtain quite a few hundred dollars in a cleverly controlled transaction.

However, once you have selected one of the accounts of World of Warcraft for sale, you have to consider seriously the new realm of your character. The conditions of the game stipulate that, after you have decided to conclude the character transfer, it is rather impossible to invalidate the process instantly. The recommendation made public is for the player to make his or her homework and explore the selected destination realm in advance to make sure it is a pleasing durable setting for the character, prior to setting off the relocation.

However, there is a manner to re-distribute the WoW character from the destination realm to a new destination realm. The single disadvantage is that you have to wait. The waiting will take the duration of three months. During this time, the character is likely to become appropriate for a further relocation.

The first version of Cubase appeared in 1989 for the Atari ST computer although the programmer, Charlie Steinberg who gave his name to the company, had been creating sequencers for the Commodore 64 and Atari since the early 80s.

The release of Cubase in 1993 on the Atari Falcon was a breakthrough in DSP software technology as realtime manipulation of audio was possible without the assistance of additional processor cards, as was the case with the more costly Pro Tools and other similar systems. Cubase also sports a well-designed and fully functional midi and score editor, which seems to come as an afterthought in many sequencers even Pro Tools. If you want to record and tweak the sound with Cubase’s native reverbs, eq and dynamics, all of the tools of the trade are there and much more improved from a graphic user interface standpoint.

Now owned by Yamaha, Steinberg is greatly benefiting from the music giants ownership. After all Yamaha is the largest musical instruments manufacturer in the world.

Designed for professionals from the ground up, Cubase 4 sets a new standard for integrated music production software by combining powerful audio and MIDI recording, synthesis, editing, mixing and effects. The brand new VST3 effect plug-in set and new first-class VST instruments are only the beginning. There are also new VST instruments, including three outstanding new synthesizers (Prologue, Spector and Mystic as well as HALion One sample player with hundreds of new instruments based on Yamaha Motif waveform), and the new Instrument Track class accelerates handling of VST Instruments and combines MIDI and plug-in automation within the same track.

Tailored for composers, musicians and project studios as well as students and educators, Cubase Studio 4 still offers professional music production technology thanks to a high-quality set of essential tools, but at a lower price point than Cubase 4.

Customers who purchase Cubase 4 will find additional advanced features required for the final production phases including surround support, full Control Room functionality and specialised plug-ins and tools for creating a final mixdown.

These music tools will allow you to write tunes in a way that more directly relates to musical notation. But the input may instead be one of the time value reporters included in the Music Tools. Pro Tools MP3 OptionBy including the Pro Tools MP3 Option, the Music Production Toolkit makes it easy to listen to a new mix on a portable device or quickly share it with other band members without having to use a separate application. We all need the proper tools to create music, and by “tools” I don’t mean acertain brand of instrument or amplifier, but rather the music we hear inside.

In Summary Cubase in my opinion at least is the Dewalt Power tool of the production world. Powerful and Reliable.

The server edition, Mac OS X Server, is architecturally identical to its desktop counterpart but usually runs on Apple’s line of Macintosh server hardware. Mac OS X Server includes workgroup management and administration software tools that provide simplified access to key network services, including a mail transfer agent, a Samba server, an LDAP server, and a domain name server.

The Carbon APIs for Mac OS 9 and Mac OS X were created to permit code to be written to run natively on both systems. For the early releases of Mac OS X, the standard hardware platform supported was the full line of Macintosh computers (laptop, desktop, or server) based on PowerPC G3, G4, and G5 processors. Later versions of Mac OS X discontinued support for some older hardware.

But Now Apple introduced FireWire audio interface for Garage Band; Apple is wrapping up development on a FireWire audio interface for Garage Band. Apple is developing a fire wire audio interface for Garage Band codenamed “Asteroid” or “Q97″.

The breakout box will include multiple audio inputs, including two XLR microphone inputs. There’s speculation that it will either be a basic Airport Express-style white box or a full-fledged transport control box, but given its price, the former seems more likely. Apple may expand music inroads with new consumer oriented hardware device.

The analog FireWire audio device, the first product of its recently created iPod division, will allow users to directly record audio using any Mac and Apple’s Garage Band music studio application.

Apple Computer is expected to introduce a new audio interface for Garage Band users. The analog FireWire audio device, the first product of its recently created iPod division, will allow users to directly record audio using any Mac and Apple’s Garage Band music studio application.

According to sources, this device will include two XLR/ TRS audio input connectors, two RCA analog output jacks, and a standard headphone jack. The device will draw power through a single FireWire 400 port and include a phantom on/off power switch.

It will be capable of automatically detecting the presence of the Asteroid device and allow users to record from 2 mono channels on 2 tracks simultaneously, or through a single stereo channel.

Typically referred to as a ‘breakout box’ in the music recording industry, the external audio device attaches to a computer and offers audio inputs and outputs for attaching instruments or other audio sources. Apple is reportedly building the device around Garage Band, its popular application for aspiring musicians.
