You will find four tabs at the top of the dialog: General, Log On, Recovery, and Dependencies. The General tab will show you the service's name, a brief description, the path to the relevant executable file, a drop-down menu allowing you to choose how should start (i.e., Automatic, Manual, or Disabled), and finally, four buttons allowing you to start, stop, pause, and resume the service.

[Restrictions or permissions] You can do this by writing a rule on the Firewall Rules tab. Click on that tab, and it will graphically walk you through writing a new firewall rule.

This tab tells your browser what should be displayed at the top of the window when the link is activated.

The HEAD tag contains the non-displaying document.

The items are tagged using the same <LI> tag.

In this case, the B tag has a color defined in the style sheet, while the FONT tag doesn't have any style rule defined for it.

Because the programmer has written the program to use the API for disk storage, the programmer doesn't have to keep up with the instruction codes, data types and response codes for every possible hard disk and tape drive.

Before you deploy your honey-pot you may want to hang a tape drive on the system and do a full backup so you can go back to square one once it gets compromised.

A LAN administrator must coordinate and keep track of all of the tapes required to back up one or more network servers.

Open something and notice how as you click backwards and forwards between the two active Desktops that the applications keep on running in the background - even if you're not using them. This lets you devote whole screens to particular jobs or tasks, while keeping the surrounding space clear from clutter.

So if you don't have a program that allows you to set these tasks at a time when you're cozy in bed, then plan it for a time when you don't need your computer.

One of the improvements of Iptables over previous systems like Ipchains and Ipfwadm is the way that it handles secondary tasks like NAT.

A hacker will make a service perform a certain task it's not intended to do and result in the computer either crashing or granting full priviledges.

When used with PnP (Plug and Play) hardware, the installation of NICs for both workstations and servers is almost an automatic task.

Network administrators access a device's IOS environment in order to perform device maintenance tasks.

The benefit is that you can easily access your mail from any internet terminal and the address is easily disposable (if it gets added to a junk mail list for instance).

That terminals connected to the terminal servers on LAN A can connect to Harpo.

Meanwhile, in the well established host environment, much is status quo, with millions of mainframe terminals networked globally, while OLTP applications and other programs pump data worldwide.

However, some text editors don't get along with the tty terminal type very well. They work better with a "VT100" type of terminal.

Telnet is a character based terminal application and is one of the granddaddy services available on the Internet for what seems like eons.

These type of terminal sessions are also called "consoles" or "virtual terminals". Using multiple consoles, logged in as root on one and some other user on another, is helpful when you want to adjust the level of access to certain files or directories for users.

At this point, the client itself may terminate, or it may simply go into a wait state until another request must be sent.

What happens if I forget to delete a block of memory before the program terminates?

When a program terminates, the operating system "cleans up after it", releasing its executable code space, stack, global memory space and any heap allocations for recycling.

Try the three-finger salute CTRL-ALT-DEL) and terminate the hung program.

Locate at the top right corner, it is used to terminate the program in the currently active window.

For example, the Maximum-Time attribute requires the server to keep tabs on how long the user has been connected and to terminate the session when the value (number of seconds) for the user has been exceeded.

Access a large file from your floppy -- for example, open a 300-kilobyte text file in a text editor.

The display provides instant feedback by showing you text and graphic images as you work or play.

Enter some text in the "Title" and "Entry Text" fields and hit the "Save Entry" button. That's it - our first blog post has been saved.

A process may start many threads or other processes, but a thread cannot start a process.

Even though two threads use different socket descriptor, all clients only send to the same end point of IP address and port number of the server.

Threads share their security privileges, and a malfunctioning thread can interfere with all the other threads in a process.

The Windows Explorer is the system tool that helps you examine and access your entire computer; files; directories; drives; desktop, etc.

Enterprise class disk array systems should come with centrally administered device management tools that allow remote monitoring and administration of performance, availability, utilization, and errors.

For speech-recognition software to be a viable office tool, it must have a vocabulary sufficient to prepare a document file loaded with technical terms, jargon and-even worse-English, where even the simplest sentence may require a fair amount of computing power.

It should be noted that newsgroups are extremely topic specific and you will receive lots of email calling you all kinds of names if you post something which does not pertain to the topic.

[Internet Relay Chat] Often an irc discussions has a topic and users will join to discuss this topic.

Lately, bloggers have become well-known commentators on the political scene, but blogging can encompass any topic or no topic at all.

The heterogeneous nature of current internetwork topology is a reality that is often overlooked by information managers when selecting technology for solving business problems.

When computers are connected to form a network, the cabling arrangement connecting these computers together is referred to as the topology.

Though both Ethernet and Local Talk are bus topology , there is a great gap between their speeds.

Get yourself a mouse or small track ball. I think a serial wheel mouse is much better than one of those little red keyboard pencil erasers or a touch pad.

The user simply moves the mouse on a flat surface, rolls the trackball, or moves their hand over the touch pad to control a pointer.

For example, some touch pads now have an invisible scroll zone - - a thin, vertical area on the extreme left or right side of the pad that can be used to page up or page down through a document quickly

These computers usually do not have keyboards but rely on touchscreen technology for user input. Palmtops are typically smaller than a paperback novel, very lightweight with a reasonable battery life. A slightly larger and heavier version of the palmtop is the handheld computer.

The touchscreen interface - whereby users navigate a computer system by touching icons or links on the screen itself - is the most simple, intuitive, and easiest to learn of all PC input devices and is fast is fast becoming the interface of choice for a wide variety of applications,

Resistive type touchscreens are generally the most affordable. Although clarity is less than with other touchscreen types, they're durable and able to withstand a variety of harsh environments.

Desktop models usually sit under the monitor and tower models beside. They come in many sizes, including desktop, mini, midi, and full tower.

Make sure you buy a case which will fit the space you intend to use it in. This is where you decide between a desktop or a tower.

As shown in the picture right, the compact MicroATX motherboard shape is 20% smaller than ATX, and there is a good range of MicroATX tower cases available, which are both shorter and shallower than regular mini-towers.

It needs to be formatted to provide a layout of tracks and segments to organise where the data is stored.

Membranes are composed of three sheets: the first has conductive tracks printed on it, the second is a separator with holes in it and the third is a conductive layer with bumps on it.

We also report the results of the CD-ROM Transfer Rate: Inside test, which measures the throughput of a CD-ROM subsystem reading the inside track of the CD-ROM, the minimal level of performance for the drive.

You choose the command that you want with the keyboard, mouse, trackball or touchpad. Commands control the operation of the software.

With a wireless, trackball-equipped keyboard and a 33.6-Kbps modem, users can surf the Internet and play games as well as watch television.

The Destination has a 6.4GB (nominal) EIDE hard drive, an EasyPhoto Drive Color Photo Scanner, a 1X DVD/12X CD-ROM drive, a wireless keyboard/touchpad, a remote control with built-in trackball and a TelePath 56K modem with x2 technology.

Anonymous FTP is an option that allows users to transfer files from thousands of host computers on the Internet to their personal computer account.

Have you ever wondered how networks work, what really happens as information is transferred from point A to point B?

Email was originally designed to handle only plain text (no formatting, ie. bold, centering, etc.) which was transferred from one computer to another in a format called ASCII.

The first step to carry out large-sized data transfers is to create nonblocking sockets.

You could also carry a short cross-over cable too, for easy two-computer networking and transfers.

TMDS takes the signal from the video adapter, determines the resolution and refresh rate that the monitor is using, and spreads the signal out over the available bandwidth to optimize the data transfer from computer to monitor.

The advantage of a Reduced Instruction Set turned out to be important in the period when chips have 2-3 million transistors (during the period of the late 486 chips and the early Pentium chips).

The switches inside your PC are microscopically small transistors. Pentium 4 chips, for instance, contain about 155 million of them.

Most LCD displays use active matrix technology. A thin film transistor (TFT) arranges tiny transistors and capacitors in a matrix on the glass of the display.

The word-processing program sends a request to the operating system, which translates the data into a format the printer understands and directs the data from RAM to the appropriate port for the printer you requested.

In order to get at the data and process it with our tools, we first need to translate the binary trace files collected with LTT into ASCII.

In essence, a piece of NAT software (usually running in a router) separates the organization from the Internet. NAT translates addresses as packets travel from the organization to the Internet and from the Internet to the organization.

Analyze the trace and output the summary and translation to the output file. There are a few other options having mainly to do with not outputting certain information.

In TCP/IP, the encapsulation in a frame and translation from IP-to-MAC address *both* occur at the network interface layer.

The I/O bus has 15 separate IRQ wires. The CPU has only one interrupt pin. The chip set on the mainboard has to provide a translation between the two.

Most clients also support transparent compression, optionally only past a certain size threshold. Both serialization and compression are possible because Memcached lets client modules store opaque flags alongside stored items, indicating how they should handle the data coming out.

Having an application in the way in some cases may impact performance and may make the firewall less transparent.

Using the Internet, the number of places through which the data has to travel is really transparent to the user.

The trojan will act upon it and reply, but the application will see none of that, the application only sees what is NOT quoted ....

Trojan - An undesirable computer program that is either hidden inside another program or that pretends to be something it is not in order to trick potential users into running it.

This means that trojan packets dont have to pass all the way along the protocol chain, up through the stack ...

MAC addresses can help you troubleshoot a number of network problems.

There are also some flow charts that you can use to troubleshoot, if you are having problems with your modem.

Your computer’s TCP/IP stack makes available a host of TCP/IP tools that you can use to troubleshoot TCP/IP connectivity problems the most useful of which is the PING command.

Ethernet's popularity continues to grow. With almost 30 years of industry acceptance, the standard is well known and well understood, which makes configuration and troubleshooting easier.

The first step to troubleshooting is looking at what you're doing and seeing if you're just stupid. Many PC problems are caused because the user did something wrong.

A LAN Analyser is a computer which "sniffs" packets off the network so they can be analysed at a later stage. Such a tool can be used for good (e.g. for troubleshooting), but also for evil (e.g. for recovering passwords or data from a network session).

"Created by Northern Webs, a Web design studio in Idaho, this online tutorial is aimed at the Internet newbie.

This tutorial can help you get started, but there is no way we can show you how to do everything.

For a tutorial covering the more basic aspects of Web search engines, including first generation search engines, see Searching the Internet: Recommended Sites and Search Techniques.

Like any other HTML graphics based program the developer will need to occasionally open the file in a text editor to "tweak" the file.

Rate limiting, packet filtering, and tweaking software parameters can, in some cases, help limit the impact of DoS attacks, but usually only at points where the DoS attack is consuming fewer resources than are available.

If you're a network administrator logging into a switch to tweak its config file, the authentication gets you into that switch's IOS command prompt.

The second method of retrieving a new page is to click on the icon in the menu bar at the top of the Netscape window entitled "Open URL". This will present you with a box in which you can type a web address.

Run - Starts a program when you type an MS-DOS command.

That means that you must type the upper and lower case characters exactly as they appear in the program.
