...340 American Military University Prof Kageorgis Throughout this paper we will review all the concepts regarding the ISDN and DSL technologies, definition, usage, benefits overall and costs. We will also compare to newer technologies overall to understand where our connections capabilities were and where they are over today’s date and where it is going. ISDN (Integrated Services for Digital Network) is a standard way to communicate digital transmission of data, voice, video and other network devices at the same at the same time over the traditional ‘’phone lines’’, basic telephone copper wires, called RJ-48 connectors. Prior to ISDN, the telephone system was only related to voice transportation, with very limited to none data service availability. The ISDN has the capability to support at least two or more connections at the same time, in any combination of voice, data, fax and video over a single line. At first ISDN speeds were only at max 128 kbits over download and upload speeds. Eventually carried over an E1, speed rates could be at 2048 kbps. (PC Magazine, 2001) ISDN-BRI (Basic Rate Interface), service is delivered through a pair of standard telephone copper wires at 128 kbps rate. Following available interfaces and their characteristics: * U Interface, usually a non-North American network, two wired interface between the network terminating unit and the exchange. * T Interface is a serial interface between a terminal adapter and a computer device, a digital...

... 2. Packet-switched or cell-switched connections 3. Dedicated connections Each type of connection has its advantages and disadvantages. This article will summarize what each connection type has to offer, with consideration given to bandwidth, availability, cost, and ease of management. Circuit-switched connections Circuit-switched connections are currently the most popular type of WAN connection. Circuit switching transmits data streams and datagrams across dedicated physical circuits. To provide asynchronous dial-in and ISDN services, the telephone companies use circuit switching. Asynchronous dial-in The public switched telephone network (PSTN) uses circuit-switched technology to provide asynchronous services (otherwise known as normal telephone service). Asynchronous dial-in connections offer a low-bandwidth, easily managed, cost-effective solution that is available almost anywhere in the world. ISDN Integrated Services Digital Network (ISDN) is a digital circuit switching technology used to transport voice, data, and video. With speeds up to 1.54 Mbps (T1) in North America and 2.048 Mbps (E1) in Europe, ISDN is a low- to medium-bandwidth solution with relatively low cost. However, availability is somewhat limited and configuration and...

...Final Notes Parity is what we use with RAM for error checking. Static RAM does not need to be refreshed. Rambus is a type of RAM not frequently used today. SMART is used with ATA hard drives. Tracks, cylinders, sectors, read/write heads are parts of a hard drive’s geometry. BIOS gives the computer initial instructions when it is first booted. Fully updating the BIOS by erasing and rewriting is flashing. New hardware, faster CPU, and new operating system are three reasons to update the BIOS. Safari is the main web browser for Mac OS X. Linus Torvalds is the person who wrote Linux. Windows Explorer is a graphical file management utility used by Windows. Open windows applications show up in the taskbar. The disk partition must be active before it can be booted. .COM, .EXE, .BAT are three types of files that can be executed from the command prompt. 255 characters are the maximum number of letters a long file name can contain. CHKDSK.EXE is the utility used to check drive errors. Biometrics is authenticating users based on physical features. Downloading free programs from the Internet is good way to protect software from viruses and malware. FALSE Disk scrubbing and wiping prevents data recovery and drive forensics.
