Common List Of Computer Peripherals

desktop photoComputer peripherals are those devices that act as I/O devices and used for operating the computers. There are so many computer peripherals are available in the market used for different types of tasks according to the users requirement or task needs. Some commonly used computers peripherals can be mouse, keyboard, joysticks, monitors and speakers. But, if we go in the depths so there will be enough to describe. Lets start a job with some of useful computer peripherals that are necessary to be used!

Headphone
Headphones are basically two sided micro-speakers used for hearing sounds from computers. Historically, first headphone was designed for US Navy by Nathaniel Baldwin but later it goes to public after the war. Headphones are divided into two main parts:
Circumaural Headphones
Supra-aural Headphones

Joystick
Joystick is computer peripheral used mainly for gaming but there are some other uses are available. Joystick was firstly invented by a German scientist Ralph H. Baer in 1944; he was also the founder of computer games.

Keyboards
Keyboard is a set of keys used to operate or input the data in the form of alphabets, numbers and symbols. Keyboard has basically more functions because it has more than 100 operational keys from A to Z, 0 to 9, F1 to F12 and some other operator keys like + – / * @ # %

Monitor
Monitor is a peripheral device that is used to display the signals from computer by receiving directions from CPU. Some years ago, we used the computer monitors with CRT technology like TV but today they are converted into LCD and Plasma technology which is sharp to see and slim in size. Some common brands for monitors are Samsung, HP, IBM, Dell and Phillips.

Mouse
Mouse is basically a pointing device used for pointing the features on computer screen and drop them where is necessary. It is considered as one of the useful peripheral devices because it has more reliability of task than keyboard. Mouse varied according to the wires, wirelesses, optical and ball functions.

Speaker
Speakers are peripheral devices used for outputting sounds via 3.5mm sound jack and sometimes external powers. Speakers are transducers that convert electromagnetic waves into sound waves and used according to your sound needs from low to high. Computer standardized sound systems are varied according to speakers like 2 means 2 speakers, 2.1 means 2 speakers and 1 subwoofer, 5.1 means s speakers and 1 subwoofer. Speakers are relied on sound cards of your computers that are also 2.1, 5.1, 7.1 and 12.1.

All of the Types of Computer Peripherals have important role regarding their processing powers and task that have assigned. These computer peripherals made our lives easy than we ever thought like some other useful computer peripherals are light pen, web cams and USB hubs.

How To Connect Dm500 With Computer

DM500 is a useful and powerful satellite TV signal receiver produced by Dream Multimedia. DM500 has a LINUX operating system, if we want to expand it usage; we have to connect it to our computer. Connecting DM500 to computer will make the edit of the channel menu according to our demand more easily. It will also reduce a lot of time if we use the RJ 45 ports to rewrite or upgrade the operating system of DM500. Using the serials port will consume 10 minutes while the unshielded twist pair will reduce more than 8 minutes. The links between DM500 and computer will also make the upload of our accounts information possible. So, it is the basic knowledge that all the fans of satellite signal receivers should have.

Before we get to operate the two devices together, we shall know the network settings of Dreambox first. We can get into the network setting interface though the way of Main Menu Settings Advanced Settings Network Settings. We will see the network information of Dreambox in the interface. We have to pay attention to the DHCP settings. If the DHCP is tick marked, it means that DM500 will get the IP automatically. If not, we have to mark the tick ourselves.

There are two ways of connecting the two devices.
1.#Connect though a router. This is the easiest method. If we use a router, we can set a LAN. There will be the method of setting up a LAN in the guide of router. The router will set up a LAN includes DM500 automatically if the option of DHCP is tick marked. The DM500 will get the IP distributed by router automatically and get into LAN. Then the computer can operate on Dreambox though LAN. If you want to upgrade or rewrite the operating system, you have to read the instruction of DM500.
2.#Using the Crossover Ethernet Cable. We can connect Dreambox and computer using the crossover Ethernet cable. The crossover Ethernet cable is not the Ethernet cable we usually use to connect internet. It is sold in shops, but we can also make one by ourselves. When we connect the both, we have to set the network parameters on computer and Dreambox. Now you should not mark the DHCP and set the IP of both devices to 192. 168. 1. 2. Then the both devices are connected.

How To Fully Clean A Virus Off Your Computer

virus computer photoIf you are anything like I am, you have been infected by at least one virus and occasionally have a really hard time removing it. I will show you to remove these tough viruses without having to rebuild your computer or pay someone big money to do so.

Ok so you notice your computer is running very slow. You run your virus scan software and find one or more viruses. You clean them up and your computer still runs slow. You cant figure out why so you run another scan and find out that the same virus is still on your computer. How does this happen?

Basically, there are viruses that will drop into protected system files or startup files that hide within your computer. Sometimes they cannot be removed without rebuilding your computer but there are a few ways around this.

First things first, get a computer toolkit ready to destroy the virus on multiple levels. I recommend a spybot scanner, adware scanner, and virus scan. Plus it always helps to have a strong registry cleaner. Once you have all of these tools ready to go, get them updated fully and download the latest versions of each if possible. After you have updated all of these tools DISCONNECT your internet connection from the computer.

It is essential to disconnect from the internet because most of the imbedded viruses will connect to their host site after the main piece is removed and will download and install itself again without you knowing. Run all of your scan utilities first and restart your computer after they have finished. Once the computer is started up, run the scans once more and restart if the virus is back. If you cannot remove the virus within three restarts, further action is required and will more than likely result in a rebuild.

If you remove it, run a registry clean to remove any leftover tag files. This will also help speed up your computer slightly. Refer to my article 5 Easy Tips To Keep Your Computer Running Smooth And Safe for more computer optimization tips. Restart once more and connect to the internet once more. You should run one more scan to verify the virus is gone. If it is we are ready to go. If it isnt removed you will have to take a couple more steps.
Use your scan utilities to find out exactly where the files are located and remove them from the registry. Be warned that removing registry files can break your operating system.

How Computer Glasses Differ From Regular Eyeglasses

Computer Glasses

Dependency on computers is increasing with time, in fact today a large number of people spend long hours on computers. This increased usage of computer makes it mandatory to take some precautions and one such important precaution is wearing Computer Glasses.

What are Computer Glasses?

Computer Glasses are eyewear that have anti-reflective lenses. These lenses block harmful radiations and reduce glare thereby enhancing vision and focus while working on a computer.

These glasses are also prescribed to reduce the symptoms of Computer Vision Syndrome (CVS).

What is Computer Vision Syndrome (CVS)?

CVS describes a group of symptoms like eye strain, dry eyes, headache, blurred vision caused by prolonged computer use. These symptoms appear because the eyes and brain react differently to words on a computer screen than they do to printed text.

Whereas, if the person is over the age of 40, the problem may be due to onset of Presbyopia- a vision disorder in which the eye loses its ability to focus on nearby objects.

The question that comes to mind is, how are these computer glasses different from regular eyeglasses?

Difference between computer glasses and regular eyeglasses:

Regular eyeglasses are prescription glasses designed to improve vision. They make things, text and images appear clearer. These glasses are generally not coated with anti-reflective coating and therefore they do not protect eyes from harmful radiations caused by computers.

Computer glasses on the other hand come with anti-reflective lenses and therefore they reduce radiations coming from gadgets like computers. These glasses also alleviate CVS symptoms and protect eyestrain and headache caused due to prolonged working on computers.

These glasses can be worn by anyone belonging to any age group and do not have any side-effects on the eyes. Those with corrective vision can ask their optician for anti-reflective coating on their lenses.

Apart from radiations from computers, these glasses also eliminate glare/reflection caused from water, snow and other flat surfaces. By reducing these glares, they enhance driving, biking and other outdoor experiences. So those with perfect vision who prefer outdoor activities more than computers or any gadgets can also opt for these glasses.

These glasses are available in various styles, ranging from vintage to modern, from rimless to full rimmed, etc. Wearer can also choose material of glasses from plastic, metal, or ultra-light titanium.

The brand conscious need not worry as they can turn their branded pair into computer glasses by changing lenses or by adding anti-reflective coating to the lenses.

Computer is unavoidable, but its effect on eyes and CVS symptoms can be avoided by wearing Computer Glasses. Make wearing computer glasses a must to enhance visual experience.

New Sony Vaio VPCEB1M1EBJ Laptop Computer

The display screen is much less amazing as we’d thought. It carries a slick finish which will reflect overhead lighting, and also vertical viewing angles are restricted. Colours are usually natural as well as energetic, however without LED backlighting, contrast isn’t as good as some screens we’ve noticed recently. The backlight isn’t as vivid as some, though it’s generally even, with just several darker patches across the bottom side.

Sony used to include a nice software program pack which includes Adobe Photoshop Elements, however that’s absent from this design. You nevertheless obtain lots of Sony utility software, even though its usefulness is questionable, and you obtain Sony’s media centre replacement, obtainable via a devoted switch above the keyboard, that is slick yet does not really add anything which Windows’ own Media Center can’t supply. Another switch starts the Vaio Care help software, which gives you entry to troubleshooting, backup as well as recovery tools.

This VPCEB1M1E/BJ laptop is the very first laptop we have seen to use Intel’s brand new Core i3 mobile processor chip, and thus we could hardly wait to benchmark it. An overall score of 77 might not sound much, nevertheless thinking about that it really is equivalent towards the fastest notebook within our current 700 computer class test, we had been duly pleased.

Intel has went with a 32nm production process for the new processors, using smaller transistor sizes, permitting the chips for being more energy efficient, having a TDP of simply 35W. Intel has also integrated a graphics processor on the chip, that gets rid of the demand for a devoted graphics chip and reduces energy usage. Sony, though, has opted to make use of a devoted graphics chip here alternatively the ATI Mobility Radeon HD 5470 for the reason that integrated chip is not successful enough for performing current 3D video games.

Sony’s brand new VPC Series is really a beautiful laptop, having a subtle two-tone design. The cover and also the region over the keyboard are a light silver colour, while on our model, the laptop keyboard panel and also wrist rest have been finished in white. The wrist rest itself has a glossy surface having a subtle twinkle, and it is manufactured of a higher quality plastic material that’s comfy to work on and also feels solidly designed.

A lot more remarkable, is that its 2.13GHz Core i3-330M is the least high priced of the brand new range of cpus; a line which additionally contains mobile Core i5 and Core i7 chips with base clock speeds as much as 2.66GHz. Every one of the different chips are dual-core and have Hyper-Threading to enhance performance while multitasking. The majority of processors within the range likewise use Intel’s overclocking Turbo Boost technology, that increases clock speeds in the event the computer chip isn’t working close to its peak temperature. Unfortunately, the entry-level Core i3 used in Sony Vaio VPCEB1M1E/BJ laptop computer doesn’t support this.

Given all this, it’s power supply rating of 3 hrs fifteen mins has been slightly unsatisfying. Nevertheless, the electric battery itself isn’t really large and also the devoted graphics chipset negates any kind of potential advantage from the processor’s onboard GPU. We have seen this like a issue when using the Sony Vaio VPCEB1M1E/BJ laptop, rather than Core i3 laptops generally. That stated, at above 3 hrs, it is still sufficient for infrequent transportable use.

This kind of good quality finish and option of fascinating materials extends throughout the whole chassis, along with attention to detail as we’d expect from a Vaio. For instance, the energy switch carries a small LED indicator where it meets the side of the chassis, so it’s nevertheless visible with the lid shut. Our mainly problem has been the DVD drive tray, which is flimsy as well as loose when open; a slot drive would have been a lot more in standing with the rest of the case.

The devoted ATI graphics card assisted the Sony Vaio VPCEB1M1E/BJ reach virtually 20fps within our Call of Duty 4 benchmark. This isn’t quick enough for gaming, but much less action-oriented games, for instance Dragon Age: Origins or Mass Effect 2 may function smoothly at reduced resolutions and with more advanced graphics settings switched off.

Hi-def movie defintely won’t be a problem, and there’s an High-definition multimedia interface port for delivering to your house entertainment system. The internal speakers are fairly loud, but tinny at higher frequencies and don’t have bass, thus if you ever wish to get the most from movies you would be advised to connect a good sound system.

Computer Forensics Chain Of Custody

As the trend for high-specification mobile phones and computers continues at a rapid pace so too does the potential for electronic media misuse and abuse. This kind of fraudulent activity is becoming more commonly seen in legal cases, particularly with employment tribunals. Legal firms are beginning to employ the services of computer forensics experts more widely in documenting electronic evidence and providing litigation support, as this can be crucial in the outcome of cases.

Computer forensics can be used to track and provide evidence in cases of intellectual property theft, money laundering, hacking, moonlighting and the accessing of illegal or inappropriate websites. Digital forensics can also help to secure concrete evidence of illegal activity not usually associated with electronic devices including blackmail, drug dealings and abusive behaviour.

Regardless of whether digital forensics is being used in a criminal case or a civil matter (even as part of an E-discovery exercise), maintaining chain of custody is vital. This is the fully documented tracking of evidence for the period of time that the forensics team has possession of an electronic device. It ensures that each member of the team can be held accountable for any action that they take with the media.

The purpose of this chain is to log the movements of the data, how it has been stored and subsequently analysed. It is essential that this documentation presents an accurate description of any copying, transportation and storage that has occurred, to prevent any potential legal challenge.

It is worth pointing out the differences between e-discovery and computer forensics. E-discovery is the method of processing and manipulating electronically stored information to be used in legal cases. This can take the form of emails, word processed documents, images and any other type of file, which can be filtered, viewed, analysed and categorised effectively via this system. E-discovery using a forensically acquired data set is crucial in maintaining the integrity of any information present, while potentially recovering any deleted material that may be appropriate for the legal proceedings.

Computer forensics is a highly complex industry that requires the latest in product knowledge and technical expertise. Specialists will have years of experience in the on-site capturing of data from computers, servers and other forms of electronic media. This data is then analysed by their forensic analysis specialists, and used to track how a particular device has been used. All areas of the chain of custody documentation will be completed to the highest standard to ensure peace of mind for the client.

Why Do Computers Crash And Break Down

It doesnt matter how expensive or luxurious a computer or laptop is. There will always come a time where they crash and break down. There are numerous reasons why systems crash. This usually results in the loss of important files and documents. Some causes may not result in the loss of data, however, when a computer or a laptop crashes, you will obviously have to bring it for repair. How can you continue working on your current assignments, reports or projects, or even have access to all of your pictures, music and videos if your PC has to be repaired? Repairing these machines will take a long time; at least a week, or even longer. Also, your CPUs condition may leave repairmen with no choice but to format it, which will result in the loss of files.

What are the other reasons why computers crash? Here are a few:

1. Due to viruses.

This is one of the most common causes of computers crashing and data getting lost. Whenever you purchase a laptop or a computer, if the seller doesnt already install an antivirus for you, they usually will recommend that you purchase a good one. They might even recommend a few. However, the problem with most people is that even if they purchase a reliable antivirus, they become extremely lazy and constantly forget to start their antivirus to maintain a clean and virus-free PC. Several people also forget and dont realize the importance of bringing up to date the program to have the latest updates for a better protection and security. These result in the accumulation of viruses in a system, which will force the PC to corrupt several files, therefore, leaving people with no choice but to delete it. This result will also force the laptop to give up and break down, which will cause numerous files to get corrupted, deleted and lost.

2. Overheating.

Desktop computers and laptops usually have built-in electric fans to help keep the system and machine stay cool, avoiding overheating. However, there are instances that commonly happen where these electric fans malfunction, therefore, causing it not to function properly, that it may not even work anymore. This will then allow the machine to overheat, which could result in a fire, hence, destroying everything. To avoid this from happening, once the equipped fans break down, immediately purchase an external fan suited for your PC. Make sure to use it every time the PC or laptop is on, to ensure that it stays cool and doesnt overheat.

3. Malicious software.

In the technology world, not only viruses exist. There are various kinds of software nowadays that contain not only viruses, but also Trojans, malware, worms, adware and so many more. These are incorporated into the system when people download illegal software, programs and files, especially from unknown sources. This will result in files getting corrupted and your PC getting affected, which will result in a crash.

4. Electricity problems.

This is another common reason, and this is one of the causes that you have absolutely no control over. Power surges and cuts can easily crash a computer and damage it altogether.
It is best that you avoid the causes that you have control over, from happening. For those that you have no control over, you have to backup your files regularly, while your laptop is still working. Dont wait for it to not work before you make a move. There are several backup programs available everywhere online and in computer stores in malls. Therefore, you should have no reason not to backup your files.
