What is computer system structure?

You are asking a big question. I will expect some consideration.

A computer is a device that can perform repetitive functions, and through a system of programming languages, yield answers to what are basically mathematical questions. The modern computer is capable of much more through the application of programs like word processors and image enhancers. Devices on a computer can make copies of digital data like Cd's and DVDs.

So here is the explanation. A computer has some basic components. It needs a processor, memory, an input and output system for data, a system for displaying data, video, and an optional system for reproducing sound, audio.

Processor. This is the brain of the computer. It is the system that utilises the languages that have been used to program a computer to do specific tasks. Like the calculator on a Windows PC. or word processing programs like the one I am using now.

Next is memory. Specifically random access memory. This is the part that stores information temporarily while you are engaging in the use of a particular application, like a word processor. It holds data while awaiting finalization. For example, if I want to change something I just typed, I can just backspace and correct it. because it is stored in temporary memory.

Then you have the input/output system. This is how we input and receive the information from the computer. It usually consists of a keyboard and mouse for input and a monitor, speakers and printer for output.

Then you have storage devices. All modern computers have a hard drive. This is a device that stores data in binary form, that is in sequences of ones and zeroes on a magnetic media. In addition, you will also have a CD or DVD device that may be capable of recording as well as reading digital data.

These are the basic components of a modern computer.

What proveds the physical connection between the network and computer?

To get connected to Network Computer must have installed & configured NIC (Network Interface Card). Then connect RJ45 port on your computer to existing Network Switch ports available in the Network with a Cat5 or Cat6 cable.

Why are the wires twisted in twisted pair cabling?

In multi pair cable sets, for example a Cat. 5 cable, the wires of each pair are twisted to prevent mutual induction into the other cable pairs. The tighter the twist, the less amount of induction into the other cable pairs.

What is the difference between a client-server network and a peer-to-peer network?

two of them are the kinds of connecting computers for resource sharing purpose. whwn we come to the peer to peer network no more than 10 computers connectd.after connecting two or more computers in to peer to peer network we can simply ping form one to another.

Definition of dynamic interconnection network?

A dynamic interconnection network is a communication network within a computer system that allows for variable routing of data between different modules or processors based on dynamic conditions. This network can adapt to changing traffic patterns and is often used in parallel processing systems to improve performance and scalability. It enables efficient data exchange and coordination among multiple components in a distributed computing environment.

What is the listening port for the Windows XP Remote Desktop?

By default the server listens on TCP port 3389

http://en.wikipedia.org/wiki/Remote_Desktop_Protocol . It can be configured to use different ports. If you are having problems connecting to some host, it might be possible that the host is behind a router and those ports are blocked. you can use :

to see if the port is open

How do you set up two networks with a single router or switch so that they both access the internet yet they cannot see nor access one another's resources?

I'm guessing that what you are trying to do is make it to where you can do either file-sharing or something similar to that on your computers but you only want certain computers to be able to file-share and what not with certain computers rather than all file-sharing with each other if not then please specify what you are trying to do and we'll go from there Ok so if you need to have multiple networks your work is done on each separate computer....the router or hub honestly has nothing to do with this unless you are trying to use internet connection sharing...then you are stuck....anyways....that out of the way...all you have to do is change the workgroup names on the computer....example if you have 4 computers A, B, C, & D and you want to have A & C on a network called "Upstairs" and B & D on a network called "Downstairs" all you would have to do is follow these steps: NOTE: These steps are written for users with Windows 2000 Professional if you don't have Windows 2000 Professional you may have to go to different options in order to change these settings 1. Right Click on the My Computer icon which is located either on the destop or the Start Menu if not both 2. Click on the Network Identification tab 3. Click on the Properties button 4. Make sure that the radio button next to Workgroup is selected and change the value to whatever you want your network name to be Now at this point if you were to setup the networks as mentioned above on you would perform all of the above steps on each of the 4 computers and on A & C when you got to step 4 you would type in Upstairs in the box and on computers B & D you would type Downstairs in the box Now this will make 2 separate networks but it will be possible for these 2 networks to be seen by each other because they will be connected by the same router or HUB and as long as the devices are connected to the same hub or router they are networked together regardless of settings. But if you use the steps above and you have password pretected your accounts on your computer the computers will be listed as being on the networks but access will not be granted to execute/copy/delete files on the networked computer unless the proper username and password has been entered Well I hope I helped you and didn't confuse you...if any part of this was unclear please e-mail me @ turtlehermit@tmail.com and let me know what part(s) is/are unclear and I will clarify it/them for you

Is it safe to use an unsecured network at home?

It is jut a bad idea all round really. If an unauthorised user connects to your network, they may visit illegal websites or commit illegal activity which will be traced back to you. You may also have some shared folders that you didn't know you had. These can generally be accessed by anyone on the network. If permissions on these folders are set to read/write then the unauthorised user may be able to delete any shared files.

What do you mean by terminology or jargon used by the student?

The term jargon means technical words or language that are not part of the average vocabulary, or that have different meaning when used within a group, field of study, or occupation.

Because the terminology is readily understood by the practitioners, it can become the usual form of communication. However, the speaker should be aware that his words may mean nothing, or something entirely different, to listeners outside of his peer group. Simpler terms should be used, or the terms should be defined.

HP and IBM are just 2 of the many that do to this day (like SUN -- recently purchased by Oracle.)
