Computer Networking

With all network topologies there is the ability to send data either way, e.g. uploading and downloading.

The three types of network media are: Twisted-pair copper cable, fiber-optic cable, and coaxial cable.

The physical address is added

You can access files from any computer.

The media connector between the NIC and the UTP cable is a RJ-45

when a computer is connected to a server it takes all the services from that server and acts as a client.

Zombie computers are any system attached to a network that silently (unannounced to the user) perform tasks on the network to reach a predetermined goal. A computer system can become a zombie computer by being infected via a network transferable source such as via email, or via a local source delivered from a flash drive or other external source. It is most common for each zombie computer to be performing a small portion of the larger goal, and be part of a larger group of zombie computers that are all working together for the same purpose. This way, if one zombie computer is brought offline, the goal can still be reached. It also ensures that each infected system is not diverting a great deal of resources to the zombie process, which helps to ensure the zombie node is not detected and repaired.

Network consequences are dependent on what the task is that the zombie collective is working on, and how many zombie nodes are contributing vs the scale of the network they sit on. For example, if 10 systems on a network of 10,000 systems are infected, the likelihood of the network being bogged down by the zombie traffic is minimal. However, it also depends on whether the goal the zombie collective is trying to achieve is targeting the local network they are on, or something outside the network on the internet, as 10 computers working to overload a local server, may achieve some results, while 10 computers trying to overload Google for instance would have little effect.

It depends on the area covered. It may also be a CAN or Campus Area Network.

The initial answer is dead wrong. You can allow remote access, but this is NOT NECESSARY for people to gain remote access to your devices. People can illegally gain access by finding holes in the security of your network and devices, and this is happening constantly. In fact, your publicly known IP address is being attacked at least every 30 seconds.

The number 1 risk is that your device is connected to the internet. Going to websites, that are not well known and trusted websites, also increases your risk by increasing the chance that your PC will have scripts downloaded, without your knowledge or consent. Porn sites are notorious, but many sites are dangerous.

To help prevent attacks, keep your anti-virus software definitions up-to-date. It is a good practice to NOT operate as your PC's administrator. If you operate as a user with non-admin privileges, the scripts that are put on your system will have to be higher level programs in order to gain access to the administrative rights that allow changes to be made to your PC. The changes made are usually to make your PC even more accessible to outside threats.

One last thing-- Back up all of your music, videos, documents, and photos to an external drive that is NOT left connected to your device.

GOOD LUCK!! I could keep writing, but I have work to do....

"Yes. But they would have to tell their computer to allow the remote access attempt."

The above is the original answer.

Network Neighborhood is the Microsoft Windows name for a way/method to browse the Local Area Network. Network Neightborhood has now become My Network Places in Windows XP. The function remains the same.

10 Mbps

Using a wireless encryption key i.e WPA (Or less secure WEP) and MAC Address filtering.

You can also stop the broadcasting the SSID, however the wireless access point can still be picked up.

YES !!!!

1) Physical layer is the first layer. 2) The simplest ones operate at the physical layer are: Repeaters, conventional hubs and transceivers. 3)These devices have absolutely no knowledge of the contents of a message. They just take input bits and send them as output. Cheers, AceInfo Solutions.

You did have to install Dimms in pairs for older computers which used RDRAMs, but computers nowadys use SDRAMs. So, you can mix combination of RAMs of different sizes and speeds without any problem.

A protocol is a set of rules and conventions that govern communication between devices in a network, ensuring that data is transmitted accurately and efficiently. Examples of protocols include the Transmission Control Protocol (TCP), which manages data transmission in a reliable manner, and the Hypertext Transfer Protocol (HTTP), which is used for transferring web pages on the internet. These protocols enable seamless interaction and data exchange in varied computing environments.

The company Sky X is a European based unmanned aircraft reseach outfit. The first of there products in the 1 tonne mass category has flown and appears to be designed more for Military compbat roles that any civil or civial uses.

FDDI Advantages:

~Supports real time allocation of network bandwidth.

~Supports a lot of different types of network traffic.

~Is fault-tolerant because it uses dual fiber cables. If one cable fails FDDI moves the data to the other dual cable.

FDDI Disadvantages:

~It's expensive

~There is always a chance of multiple ring failures and as the ring grows, that chance increases.

~It's not used frequently due to cost, companies prefer to use copper (CDDI) if they are taking the ring approach.

IPv4 was described in RFC 791 in September 1981.

decryption is the process of extracting the original information from the encrypted data.

First the advantages. A secure network has much less likelihood of unauthorized access which could result in corrupted data, stolen data, or malicious damage to a database. Some form of encryption is usually used to make data unreadable even if it is stolen. The chief disadvantage is slowdown of the system. Encrypted data must be un-encrypted, users have to be verified, some IP addresses have to be blocked, etc.

Magnetic tape backup of your data is done with a magnetic tape data storage system. You can use digital recording to store your digital data on the magnetic tape as a backup.
