Computer Networking

its when the sending device keeps a copy of the last frame transmitted until it receives ACK. Keeping a copy allows the sender to retransmit lost/damaged frames until received correctly.

If the receiver detects error in frame, it discards it and sends no ACK

google search engine used it all along.

me and you can! all you need is Microsoft Powerpoint, a picture and/or movie editor (optional) and a game in your head, Just make a slide show with several slides that you link together with hyperlinks. Use the movie and picture editors to add movies and pictures to copy and paste to your slide show

An expansion bay is a large slot typically located in the front of a desktop PC. Expansion bays are used for adding additional hard drives and optical drives to your computer. They can be used for other special devices as well.

The cost of fiber optic cables can vary depending on factors such as length, type of cable (single-mode or multi-mode), manufacturer, and installation requirements. On average, the cost can range from a few dollars to over $1 per foot for standard indoor fiber optic cables. Outdoor, armored, or underwater fiber optic cables can be more expensive. For long-distance, high-capacity installations, costs can be significantly higher.

Plenum refers to a type of building and how its air is exchanged. When a bulding is on fire and the cable starts to burn it gives off toxic fumes and will kill you. Plenum cabling is coated differently for burning purposes.

It depends on what you are using it for. I am using one with no modem to connect to my printer.

An operating system can be defined as a global application that acts as an intermediary between a computer user and the computer hardware. It manages the hardware and software resources of a computer. It allows the computers to run programs. An operating system allows the computer to start and function. It allows you to navigate your computer. It allows all the components of a computer to operate together to do tasks such as printing text to a printer. A word processor application sends its print request to the Operating System and the operating system carries out that task. A computer would likely be unusable without an operating system, unless the software is able to act as its own OS.

The goals of Operating system is to execute user programs and make solving users problems easier, to provide a convenient environment for the development and execution of programs, and to schedule computational activities to insure good performance of the computing system. Some operating systems are more user friendly than others. Ideally, the system should include easy to use icons, and easy to use pop-up instructions as needed. It can either be a graphical user interface (such as Windows, Mac, OSX) or a command line (Linux/Unix/DOS). It is the background in which all other applications and services run.

An operating system has two primary functions. Firstly, it dictates to application programs what they can and cannot do. Secondly, it manages the computer hardware on behalf of applications. The two functions are not unrelated.

It also manages execution of user programs to prevent errors and improper use of computer and operations and controls of I/O devices. If you had two applications, A and B running on the same computer, and no operating system to supervise them, then program A could overwrite the memory occupied by program B, or vice versa, program A could overwrite program B's files on disk. You could have the two programs trying to read from the same keyboard, or print on the same printer, simultaneously, and so on.

Additionally, if there was no operating system to manage the hardware, then applications would need to concern themselves with the minutiae of how to save data to disk by programming the hard disk controller, or obtain input from the keyboard by interrogating the keyboard controller, instead of getting on with the calculation of somebody's payroll, or whatever else that application was supposed to do. Computers with no operating systems relies on the application programs to manage minimal hardware. For instance, application programs would need I/O support libraries.

the word research means to find out or to look for information that is not yet already known by the one who is researching.

There are at least 9 bits. 8-bit data, even parity, means an extra bit called a parity bit is sent along with the data to make the number of 1's even in the total number (including the parity bit). There might be more than 9 bits, if start/stop or other bits are used in the code. For example, the data value 00000001 (8 data bits), if even parity is used, an extra bit would be sent thus: 100000001 (total number of 1's is 2, even). If the value of the data was 00000011, then the parity bit would have a value of 0, 000000011, so the total number of 1's is even in the entire string. The purpose is so that on the receive side you can use a simple 1-bit adder to do a sanity check on the received data to see if the correct number of 1's was received in a given byte being received. If even parity was sent, and odd parity was calculated on the receive side, that data byte can be flagged as in error and possibly dropped.

sort of........................................megaman NT warrior did make more but only around 100 episodes were dubbed in the united states but the others were never translated in America but only aired in Japan.

Once you see your computer's desktop, your computer has already booted. However, this does not mean that all of your computers programs have already loaded. For some time after your computer has booted there are other programs that are still starting up. If you try to play a video game while these programs are still starting your computer will run very slow since it is trying to both run your game and start these programs at the same time.

you can open the explorer bar called history but that's the ones youvebeen to but havent deleted

The following data fragment occurs in the middle of a data stream for which the byte-stuffing algorithm described in the text is used: A B ESC C ESC FLAG FLAG D. What is the output after stuffing?

Most operating systems can only be removed by formatting the hard drive, and then installing the operating system that you desire. The drawback to this is that you will lose everything that is on that partition of the hard drive. Example : if you have a computer with Windows Vista but you want to put Windows XP on the computer you have to wipe (format) the hard drive in order to load Windows XP. This means saving all your documents to a CD or another hard drive or another partition. If you want to upgrade to a newer operating system then this can be done without losing your information, but some programs may need to be reloaded. Hope this helps. ----

Python script?

It can connect unlimited

A PDA would only include NOS components if they were designed to work on a network, particularly wireless networks. The more inexpensive PDAs do not do that, and have no network software. The higher end PDAs will have the required software in order to connect to a network.

A denary number is a number based on the ten digits, from 0 to 9. This is in contrast to the binary system used in computing, which consists entirely of 0s and 1s.

B class pipe is heavier.

layered model architecture is tcp/ip model .you can reference this model as layered model architecture protocol.

Because now a days it is cheep and from vpn you can send the data securely. Because VPN split the datas into smaller cells as well send it through different routes.
