Lag
From Wikipedia, the free encyclopedia
Jump to: navigation, search
For other uses, see Lag (disambiguation).
Lag often refers to delays experienced in computing communications, however it may also apply to written or other forms of communication.
Within computing, Lag refers to the time taken for a packet of data from the sending application to the receiving application. This includes both transit time over the network, and computer processing time at both the source and destination computers.
Whilst in the strictest sense every packet experiences lag, the term lag is implied to refer to noticeable delays to the user caused as a result of extended or unexpected delay. As the time taken for a packet to travel from a server in Europe to a client nearby in the same region is likely to differ from a trip from Europe to the Americas or Asia, it is possible that two users may experience connections to the same server with a different extent of network lag.
QUOTE
Causes of delay
Lag may be traced to two main sources:
Inadequate network performance
The packets are either interrupted along their path by faulty routers, the network cannot handle the number of packets sent/required (see: bandwidth) or the packets pass through an unusually large number of routers before reaching their destination.
Inadequate processing power
Lag may be experienced where the user submits an unusual request which is not yet cached, or where the reply requires a large amount of processing before it can be sent. This affects multiplayer gaming . The bandwidth of an area which the packets would normally pass through quickly may be disrupted during working hours (for example), thus the packet would need to 'queue' at each router before being sent onwards.

Gaming
Lag, from "lag behind" and Warp, from "warping", are slang terms for slow Internet speeds or Internet latency; Lag is sometimes due to a server problem, but more frequently due to the connection between client and server. A slow or intermittent connection may often be referred to as laggy.
LAGi natin naririnig at nababasa term na ito.
DIAL-UP
QUOTE
Dial-up access is a form of Internet access through which the client uses a modem connected to a computer and a telephone line to dial into an Internet service provider's (ISP) node to establish a modem-to-modem link, which is then routed to the Internet.
QUOTE
Performance
Modern dial-up modems typically have a maximum theoretical speed of 56 kbit/s (using the V.92 protocol), although in most cases only up to 53 kbit/s is possible due to overhead and FCC regulation. These speeds are currently considered the maximum possible; in many cases transfer speeds will be lower, averaging anywhere between 33-43 kbit/s. Factors such as phone line noise and conditions, as well as the quality of the modem itself, if the modem is external or internal, all play a large part in determining connection speeds.
Dial-up connections usually have high latency that can be as high as 200 ms or even more, which can make online gaming or videoconferencing difficult, if not impossible.

DIAL-UP Connection.
• Check your phone line.
ºº maingay ba yung dial-tone, grounded.
ºº wires > wear-out na ba? baka nginat-nat na ng daga etc.
ºº Kung kinakailangan, tumawag ka sa Telephone provider mo.
• Modem
QUOTE
A modem (a portmanteau constructed from modulate and demodulate) is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information.
sample of an internal modem http://computer.bizhat.com/images/modem.gif
External 56k modem http://www.greatcanadianreviews.ca/usb_serial_modem2.jpg
ºº Check niyo ang wirings lagi, kagaya nung phone lines, power supply etc.
• Use good Internet ServiceProvider
I recommend these:
ºº ISP Bonanza - affordable packages found here http://www.ispx.com.ph/bonanza/
dati 440 / month unlimited . Mabilis connection nila wether bayantel or PLDT ka.
ºº for PLDT subscriber - syempre Vibe
ºº for BAYANTEL - Blast
For DSL Connection
• almost same as dial-up check niyo yung wirings
• for Smart-Bro user, mag reklamo kayo pag laging below 200 kbits/s ang speed niyo. negotiate if kailangan pa dagdagan ang height ng antenna.

Spyware
QUOTE
Malicious websites may attempt to install spyware on readers' computers.
In the field of computing, the term spyware refers to a broad category of malicious software designed to intercept or take partial control of a computer's operation without the informed consent of that machine's owner or legitimate user. While the term taken literally suggests software that surreptitiously monitors the user, it has come to refer more broadly to software that subverts the computer's operation for the benefit of a third party.

Spyware's brothers
Virus
QUOTE
A virus is a manmade program or piece of code that causes an unexpected, usually negative, event. Viruses are often disguised games or images with clever marketing titles such as "Me, nude."
WORM
QUOTE
Computer Worms are viruses that reside in the active memory of a computer and duplicate themselves. They may send copies of themselves to other computers, such as through email or Internet Relay Chat (IRC).
Trojan Horse
QUOTE
A Trojan horse program is a malicious program that pretends to be a benign application; a Trojan horse program purposefully does something the user does not expect. Trojans are not viruses since they do not replicate, but Trojan horse programs can be just as destructive.
For Spyware's brothers I recommend
McAfee
Opinion: Para sa akin mas ok effective ang McAfee instead of Norton, AVG and others.
