When will the internet run out of space?
The current specification for IP addresses: (255.255.255.255)
IPv4 uses 32-bit (four-byte) addresses, which limits the address space to 4294967296 (232) possible unique addresses
The new specification for IP addresses: (3ffe:1900:4545:3:200:f8ff:fe21:67cf)
IPv6 has a vastly larger address space than IPv4. This results from the use of a 128-bit address, whereas IPv4 uses only 32 bits. The new address space thus supports 2128 (about 3.4×1038) addresses.
So the internet will run out of space when our current specification limit is reached (pending switch to the new spec)
What does the 'front side bus' do for a processor?
Also known as the "FSB", connects the memory and all of the other devices on your motherboard to the CPU (processor). You can think of it like a highway that carries the data around "Motherboard City". The speed of the FSB is expressed as a frequency (it's clock speed) in MHz (MegaHertz). One MHz is one million cycles per second. The FSB also has a "width", expressed in bits, such as 16 or 32 bit etc.. The wider it is, the more data can be transferred in one clock cycle. So, for example, a motherboard featuring "266 FSB" means that it's FSB runs at 266MHz and is usually 32 Bits wide. Although with "true" 64 Bit processors becoming widely available, the bit width can be 64 bits wide.
What are the difference between a gift card and gift voucher?
The practical meaning of the terms 'gift card' and 'gift voucher' may vary depending on the issuer. Rarely, the two phrases are used interchangeably. However, generally speaking a gift card is less restrictive (it can be used in place of cash towards any purchase at a given vendor) and has a longer shelf life (expiration date is farther away). Gift vouchers, on the other hand, can be for specific items only or have other strict restrictions that apply, and are not usually considered the same as store cash.
Difference between 4 diodes and 2 diodes rectifier?
a 2 diode rectifier is a center tap rectifier an a 4 diode rectifier will be a bridge rectifier
***********************************************************
A two-diode rectifier is not always a centre-tap rectifier.
If the two diodes are connected to the same end of a transformer's secondary, one by its anode and one by its cathode, one will proved a positive voltage with respect to trhe other end of the winding and the other will provide a negative voltage.
(But perhaps that isn't considered a two-diode rectifier - but a two single-diode ones.)
Differences between 115 volt and 120 volt?
These are different ways of measuring voltages. In the united states, people often refer to the standard household electricity as "110 volt", because that is close to the average voltage over time that the sine wave will be at. 115 is was MOST electric companies actually produce, on average, and 120 volt is the RMS measurement of that voltage. The peak voltage at the top and bottom of the sine wave will usually be close to 125 volts. For more information, please google for how AC works.
What are the Differences between a search engine and a website?
Yes there is in fact. It's a small difference but one anyways. A search engine is just that it searches, and in the context you are talking about its a web search engine but the term "Search Engine" can apply to many other things. A Web portal is more like yahoo. They offer mail, the weather, news, etc etc on the front page as well as a search Engine.
What is the difference between 1080i and 1080p?
HDTV 1080i is an interlaced picture and 1080p is progressive. HDTV 1080p is the shorthand name for a category of video modes. The number 1080 represents 1,080 lines of vertical resolution[1], while the letter p stands for progressive scan or non-interlaced. 1080p is considered an HDTV video mode. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal (display) resolution of 1920 dots across and a frame resolution of 1920 × 1080 or exactly 2,073,600 pixels. The frame rate in hertz can be either implied by the context or specified after the letter p (such as 1080p30, meaning 30 frames per second). 1080p is sometimes referred to in marketing materials as "True High-Definition" or "Full High-Definition". Although 2K/4K digital cinema technology is commercially available, and ultra-high definition video is in the research phase, 1080p and 1080i are currently the highest-resolution formats widely used for broadcasting and consumer distribution of video content. 1080i (pronounced "ten eighty I") is shorthand name for a category of video modes. The number 1080 stands for 1080 lines of vertical resolution, while the letter i stands for interlaced or non-progressive scan. 1080i is considered to be an HDTV video mode. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels and a frame resolution of 1920 × 1080 or about 2.07 million pixels. The frame rate in hertz can be either implied by the context or specified after the letter i. The two frame rates in common use are 25 and 30 Hz, with the former (1080i25) generally being used in traditional PAL and SECAM countries (Europe, Australia, much of Asia, Africa), the latter (1080i30) in traditional NTSC countries (e.g. United States, Canada and Japan). Both variants can be transported by both major digital television formats, ATSC and DVB. 1080i vs 1080p To compare 1080i and 1080p it is important to compare framerates. Due to interlacing 1080i has twice the frame-rate but half the resolution of a 1080p signal using the same bandwidth. This is especially useful in sport-shows and other shows with fast-moving action. However, on some flat screens that don't support interlacing, this instead becomes smeared or jarred artifacts. Current digital television broadcast systems and standards are not equipped for 1080p50/60 transmission. Also, the majority of consumer televisions offered for sale are currently not equipped to receive or decode a 1080p signal at any frequency. It is less bandwidth-intensive to broadcast a film at 1080p24 than 1080i30, since 20% less data would be transferred. In addition, when the source material is 24 frames per second, as are most films, it would be easy to convert a 1080p24 broadcast to an NTSC 1080i30 format using a 3:2 pulldown process (see telecine). Moreover, displaying a p24 broadcast on an i50 system (such as PAL) requires the speed of video and audio be increased by over 4% (to 25 frames per second). For movies the frames (25 or 30 per second) are segmented into two interlaced fields with equal time index (psf, progressive in or with segmented frames). The deinterlacer has to perform a simple weave only. This ensures compatibility with 1080i25/30 with only little less coding efficiency than 1080p25/30 and half the bandwidth requirement of 1080p50/60, but the SDTV problems of PAL speed-up and Telecine judder remain. 1080i is better
Difference between active and passive devices?
Active device:
A device that requires an external source of energy to be ready for operation and has an output that is a function of present and past input.
e.g, Diodes, Transistors, PN and PIN junctions, ICs and varactors etc. we have to apply an external voltage usually called as Vcc, to these devices before placing in circuit network.
Passive device:
A device that does not require a source of energy for its operation.
e.g, such as Resistors, Capacitors, Inductors, etc. We place thses devices in the circuit, network without applying any external voltage.
Whats the difference between a firewall and a antivirus system?
Answer
A firewall is a software componet that regulates the internet use of programs already installed on your system. Most firewalls do only that. However, there is something called a 2 way firewall. A 2 way firewall is a firewall that scans files being downloaded to your computer and stops unauthorized programs from using your internet connection to visit websites. Why is a 2 way firewall best. Well it helps to stop the potentially harmful code or malware as it usually called from infecting your computer. By anti virus system you must mean anti virus software. Anti virus software is programs that try to search for, find and remove or neutrilize a virus.
A simple firewall like the Windows Firewall in XP and Vista protects you from outside attack by making your computer's ports invisible to outsiders and by refusing to accept incoming data packets that were not requested. Third-party personal firewalls also control which programs can use your Internet connection to contact sites outside your computer - so they offer two-way protection.
An antivirus utility scans the files and Registry on your computer to detect and remove viruses and other malicious software. Its realtime component prevents malicious programs from installing or launching in the first place.
The two are quite different and both necessary.
What is the difference between electrocardiograph and electrocardiogram?
An electrocardiogram (ECG or EKG, abbreviated from the German Elektrokardiogramm) is a graphic produced by an electrocardiograph, which records the electrical activity of the heart over time. Its name is made of different parts: electro, because it is related to electrical activity, cardio, Greek for heart, gram, a Greek root meaning "to write". In the US, the abbreviation "EKG" is often preferred over "ECG", while "ECG" is used universally in the UK and many other countries.
What is the difference between inbox and spam in the Gmail?
Inbox is the primary place where emails are shown. Emails that you either archive or delete from your inbox will also be gone from other email accounts. Inbox is a more curated place for your emails, it does not require as much effort to find what you need as spam does.
What are the needs for conversion between analog and digital data?
We like to convert audio signals to a digital signal. First, as a digital signal, it can be moved around many times without degrading during transmission. Old vinyl records would eventually wear out and get scratched. Tapes would wear out and the signal would be degraded. Not so with an audio track that is digitized. The data string is easier to "protect" than the vulnerable records or tapes. It's not going to degrade or "wear out" from playing. Also, digital audio can be stored as a digital file in contemporary computer- or microprocessor-based storage systems. This kind of storage can suggest that it can be kept around indefinitely. Certainly since it's a digital data string, it can be stored a "long time" without fear of degradation of the media, like with records or tape. Another advantage of converting audio to a digital signal (and a biggie) is that as a digital signal, it can be processed to achieve almost limitless effects. The clever designs of digital signal processing software make these applications powerful manipulators of any audio that is pushed through them in the form of a data string. The end product is constrained by almost nothing but the creativity (and the skill at using the software) of the person sitting at the keyboard of the computer. Got links if you want them.

What is an symmetric cryptography?
both parties share the same key to encrypt and decrypt
- Symmetric encryption means that an encrypted file can be decoded simply by reversing the way it was coded. If we consider it in terms of a padlocked box, the same key that was used to lock it, can be used to open it once again.
In terms of files this means that if you encrypt a file using a password, that same password can be used by anyone who knows it, to decrypt the data. The disadvantage of this is that whenever you encrypt a file and send it to someone, you must make sure that person also knows the password you used.
This is why asymmetric encryption exists whereby one person can encrypt and send a file to someone else using "public key cryptography". The short definition of this is that encrypted data is not decrypted in the same way which means that there is no need to have a prearranged password.
What is the difference between high level language and machine language?
The difference between high level languages and machine languages are as follows: 1)Machine language uses binary numbers/codes but high level languages(HLL) use key words similar to English and are easier to write. 2)Machine Language is a Low level language and is machine dependant while HLLs are not.
What is the difference between inter domain routing and intra domain routing and what are they for?
Routing algorithms that are restricted to only work within the domain are referred as intera-domain routing algorithms and if they are not restricted only within the domains then they are inter-domain algorithms.
What is the difference between a regular cell phone and VoIP phones?
VoIP stands for Voice Over Internet Protocol and is a software which is used to communicate over the internet using a microphone which is connected to your computer. The drawback to this is that you must be at your computer in order to make your call compared to the portability of a cell phone, however, using VoIP is free.
How much does an industrial engineer earn in south Africa?
How much an industrial engineer can earn in South Africa depends upon experience and location. The average salary for this occupation is said to be R 248,017.
What is the difference between a DVD and Blu-ray player?
Blu-Rays are used only for high definition. Blu-Rays hold up 5 times more data than a DVD can hold. Blu-Rays have capabilities that are way ahead of DVDs, such as accessing the bonus material while watching the movie
What is the difference between computer literate and computer literate?
Literacy means you can use a computer to a basic degree.
Competency means you are highly experienced and capable of using a wide range of applications, performing various tasks, and are able to learn or 'guess' how to utilize new applications based on common experience with similar.
IE, how Microsoft Word is very similar to OpenOffice's Writer.
What is meant by low level formatting?
Low-level formatting is the process of outlining the positions of the tracks and sectors on the hard disk, and writing the control structures that define where the tracks and sectors are. This is often called a "true" formatting operation, because it really creates the physical format that defines where the data is stored on the disk. The first time that a low-level format ("LLF") is performed on a hard disk, the disk's platters start out empty. That's the last time the platters will be empty for the life of the drive. If an LLF is done on a disk with data on it already, the data is permanently erased (save heroic data recovery measures which are sometimes possible).
If you've explored other areas of this material describing hard disks, you have learned that modern hard disks are much more precisely designed and built, and much more complicated than older disks. Older disks had the same number of sectors per track, and did not use dedicated controllers. It was necessary for the external controller to do the low-level format, and quite easy to describe the geometry of the drive to the controller so it could do the LLF. Newer disks use many complex internal structures, including zoned bit recording to put more sectors on the outer tracks than the inner ones, and embedded servo data to control the head actuator. They also transparently map out bad sectors. Due to this complexity, all modern hard disks are low-level formatted at the factory for the life of the drive. There's no way for the PC to do an LLF on a modern IDE/ATA or SCSI hard disk, and there's no reason to try to do so.
Older drives needed to be re-low-level-formatted occasionally because of the thermal expansion problems associated with using stepper motor actuators. Over time, the tracks on the platters would move relative to where the heads expected them to be, and errors would result. These could be corrected by doing a low-level format, rewriting the tracks in the new positions that the stepper motor moved the heads to. This is totally unnecessary with modern voice-coil-actuated hard disks.
More input from FAQ Farmers:
- The only time you could low level format a new voice coil hard drive if it you would have bad sector that are not being taken care by the hard disk logic. Most of the time you will have a utility to do this task that comes from the manufacturer of the drive and it will not work with any other brand. Maxtor and late quantum has a utility called Max blast plus and power max and others. They are used to diagnostic but also to fix at the low level.
- Those utilities can many times restore an unstable drive by reformatting at the low level and blocking out bad sector. Of course if the RLL (magnetic data) is low because the read write hardware is defective it will do no good. If the surface was damaged it could give the drive a new life.
- There is also an application called Spinrite (by Steve Gibson) It's not a low level format in itself but it reads and rewrites the data (at the low level) while analyzing the disk. Spinrite is over 17 years old and has been updated to the new technology ever since version 1 (current version is 6). I's a very respected software by all the hard disk service technician around the world. Steeve Gibson is one (if not the best) of the best hard disk low level white hat hacker in the world.
- No software of any sort can truly low-level format today's modern drives. The ability to low-level format hard drives was lost back in the early 1990's when disc surfaces began incorporating factory written "embedded servo data". If you have a very old drive that can truly be low-level reformatted, SpinRite v5.0 will do that for you ( But this is only possible on very old non-servo based MFM and RLL drives with capacities up to a few hundred megabytes. You can still read and write from that "so called" low level but not in the same way it was original;y possible then with old drives.
A standard toolbar is exactly what it sounds like - a toolbar with a set of standard controls, the one smost commonly used with a program. This can change from program to program but generally the standard toolbar contains commands such as: Open, New, Save, Print, etc.
