How do you connect 2 PCs using large connection at rear of PCs?

For one more details is needed to determain what Port you are talking about is pins male or femail is it a jack or usb port. The only thing i can guess is a serial port and that is (old technoligy) sort of speak but if you can find a cable you just connect the two to gether and find a bridging software. The best to connect through 2 computers is really the ethernet port eaither directly or through a network then you can go into network managment and set up then

What is the wep code for 2wire064 on the ds?

Assuming you have a real 2Wire, Inc. wireless gateway/router, and you are still using your factory default WEP key, it is printed on the bottom of the router. It is a 10-digit number and that is what you would enter into your Nintendo DS to get it on the Internet.

A) thin client computing

B) server side processing

C) mainframe computing

D) Terminal Services <<<

Discuss final method and final classes?

a method declared final can not be overridden, and a class declared as final can not be extended by its sub class.

Why is Conan on cable?

Conan is on cable because Conan quit network TV because he did not want his show on at midnight.

How much does it cost total to go to wireless from wired networking?

The cost associated to go wireless will depend on many factors inclduing how many computers will be on the network.

How does SFP works?

SFP (Small Form Pluggable) optical modules are the most used fiber optic transceiver modules in the fiber communications industry. SFP's come in a variety of data rates and different fiber coverages. Most used SFPs are the 1.25G Gigabit rate transceiver modules. This section also includes wider old format GBIC only transceivers with SC connectors.

What would cause a coumpter to lock up all the time to were you have to reboot?

Too many programs running in the foreground/background, not enough RAM, Virus, dying hardware of some sort.

What is the difference between passive and active FTP?

A client can ask an FTP server to establish either a PASV (passive-default) or a PORT (active) connection for data transfer. Some servers are limited to only one type of connection. The difference between a passive and an active FTP connection lies in whether the client or server initiates the data connection. In passive mode, the client initiates the connection to the server (port 20-default(; in active mode, the server initiates the connection. Neither is inherently more secure than the other.

What is the meaning of throughput in aviation?

In aviation, throughput refers to the capacity of an airport or air traffic control system to handle a specific number of aircraft movements or passengers within a given time frame. It measures the efficiency and effectiveness of operations, including takeoffs, landings, and passenger processing. High throughput indicates that an airport or system can accommodate more traffic, thus reducing delays and enhancing overall performance. Factors influencing throughput include runway availability, air traffic control procedures, and terminal capacity.

Compare and contrast a PC operating system and a NOS?

In order to support multiple concurrent users and to provide shared access to network services, resources, and devices, NOS servers must run operating systems with characteristics that extend beyond those of client PCs. A number of operating systems such as Linux, Windows NT/2000/XP, and Novell NetWare can integrate the features that are required to function as a NOS server.

A system capable of operating as a NOS server must be able to support multiple users concurrently. The network administrator creates an account for each user, allowing the user to connect to and logon to the server system. A user account on the server enables the server to authenticate the user and to allocate appropriate resources the user is allowed to access. Systems that provide this capability are called multiuser systems. UNIX, Linux, and Windows NT/2000/XP all support this multiuser capability.

A NOS server is a multitasking system. Internally, the OS must be capable of executing multiple tasks or processes at the same time. Server operating systems accomplish this with scheduling software that is built into the execution environment. The scheduling software allocates internal processor time, memory, and other elements of the system to different tasks in a way that allows them to share the systems resources. Each user on the multiuser system is supported by a separate task or process internally on the server. These internal tasks are created dynamically as users connect to the system and are deleted when users disconnect.

Another feature of systems capable of acting as NOS servers is the processing power. Ordinarily, computers have a single central processing unit (CPU) that executes the instructions which make up a given task or process. In order to work efficiently and deliver fast responses to client requests, an OS that functions as a NOS server requires a powerful CPU to execute its tasks or programs. Single processor systems with one CPU can meet the needs of most NOS servers if they have the necessary speed. To achieve higher execution speeds, some systems are equipped with more than one processor. Such systems are called multiprocessing systems. They are capable of executing multiple tasks in parallel by assigning each task to a different processor. The aggregate amount of work that the server can perform in a given time is greatly enhanced in multiprocessor systems. Servers of this nature are sometimes referred to as enterprise servers because of their capacity to handle large and multiple services. Enterprise servers are also capable of running concurrent copies of a particular command. This allows them to execute multiple instances of the same service or program call threads. A thread is a computer programming term that describes a program which can execute independently of other parts. Operating systems that support multithreading enable programmers to design programs whose threaded parts can execute concurrently.
