Over the past decade, wireless network use has grown from just something done in computer science departments at universities to something done in the home, restaurants, and just about anywhere. SSID (Service Set Identifier) is the term that describes the wireless network name. It distinguishes between networks that may be in range of a device …
A Bessel filter is a linear filter that is used in electronics and signal processing and has a flat group delay (also referred to as a maximally linear phase response). These filters are commonly used in audio crossover systems and preserve the wave shape of any filtered signals across the group delay in the passband. …
Linear amplifiers are electronic circuits that have an output that is proportional to the input of the device while providing additional power to the load. A linear amplifier is normally a variant of a radio-frequency (RF) power amplifier and is used frequently in amateur radio and in laboratory and commercial audio equipment with an output …
A Capacitor Bank is a group of several capacitors of the same rating that are connected in series or parallel with each other to store electrical energy . The resulting bank is then used to counteract or correct a power factor lag or phase shift in an alternating current (AC) power supply. They can also be …
The Server Message Block (SMB) protocol is designed to support file sharing, serial ports, printers, and other communications interfaces such as mail slots and named pipes established between two or more computers. The protocol can be used on top of the TCP/IP or other network protocols such as NetBEUI on the Internet. SMB primarily allows …
The Interior Gateway Routing Protocol (IGRP) is a network routing protocol that is designed to enable routing inside of an Autonomous System (AS). Cisco developed this protocol in the late 1980s in response to the existing Routing Information Protocol’s (RIP) shortcomings. As Cisco routers became more popular, a number of large networks began using IGRP, …
A timeline is a tool used in a visual presentation in order to present data or unique events in a sequential fashion over a defined time frame. In the past, unique programs such as the Adobe or Corel tool suites were the only programs available to individuals capable of creating a professional product. Microsoft Word …
PuTTY is an open source terminal emulation program that accesses Telnet, SSH, and other TCP protocols and acts as a serial client for computers. The letters “TTY” in the name PuTTY represent the terminal application in the Unix and Linux Operating Systems (OSs) and is also short for teletype. The PuTTY application was first written …
Microsoft has bundled their basic Firewall application with the Windows Operating System (OS) since Windows XP SP 3. The firewall is used to provide consistent protection against Internet intrusion and attacks on computers and will block connection attempts that have previously been associated with malicious behavior. Error 0x8000ffff can be generated when the Microsoft Firewall …
Skype has grown to be one of the most used applications for real-time video, text, and voice chat. The service allows consumers to make free computer-to-computer calls. Consumers may also make phone calls to all types of telephones at a cost. Skype also has a built-in search function that finds people online on Skype based …
