Computers and monitors don't care which style of cable is used.

USB-A plugUSB-B plugCAUSBACAUSBB CAUSBAMF

Free Technical Repair Tip: USB Universal Serial Bus: connection on "new" computers for all "plug & play" accessory devices. Windows 98 era computers usually have two(2) USB ports for accessories in addition to DB9 serial COM ports, DB25 Parallel (printer) Port, HD15 (Monitor) socket, PS/2 Mouse and Keyboard sockets etc.
USB-A "flat" connector (both sides of CAUSBA above) that plugs into the computer
USB-B "square" (left side of CAUSBB above); plugs into "device" (Camera, Flatbed Scanner, Printer, etc)
USB-1 requires Windows 98 operating system; higher speed than DB9 Serial Port.
USB-2 requires Windows XP or higher operating system; higher speed than USB-1. USB Cables are identical regardless of label as "USB-1" or "USB-2."

Free Technical Repair Tip Laptop Computer Power Jack Repair: portable computers have power jacks soldered to a circuit board--so they break easily & it is difficult to find a replacement that matches the circuit board! A "nut-mounted coaxial power jack" can be installed with wire from the circuit board to a hole you drill in the case: PH-247, PH-248, CR-30-310, CR-30-311, CR-30-314, CR-30-315. You may need to change your power supply connector to match the jack you select.

Glossary of Computer Terms
10BaseT: an 8-contact RJ45 connector found on modems.
286 These 10Mhz processor computers can connect to other computers at 9600 baud.
386 This type of computer could connect to other computers using a 14.4K modem.
486 This computer typically operated at 66Mhz and could use a 28.8K modem for internet connections.
586 "Pentium" computers are compatible with 56K modems for internet connections to other computers.
Bits and Bytes Computers use 8 bits to a byte (letter, number or punctuation mark).
Centronics was an early manufacturer of printers that used a 36 contact Cinch plug on their printers. Other manufacturers copied them so this connector became known as a "Centronics" plug; a pair of spring-wire anap-clips hold it to the panel mounted jack. Old printers use cables with a DB25 plug at the computer and this 36-contact plug on the printer. Bi-Directional printer cables have 25 conductor wire (so the printer can tell the computer to stop sending when the printers buffer memory is full); unidirectional printer cables have 18 wires.
DSL (ADSL) High speed internet connection from the phone company. Speed Stream 5360 or Speed Stream 4100 are external modems provided by SBC/AT&T for customers.
Ethernet term for connecting computers together; using "thinnet" (BNC) RG58 or Plenum wire. Local Area Networks commonly use twisted pair (RJ45) Cat 5/E or Cat 6 wires; DB15 connectors can also be used for networking.
External Modem: Computer end of coble plugs into DB-9 "Com" Port; Modem end of cable may be DB9 or DB25. (Some modem cables have both DB9 and DB25 connectors at one end).
Firewire IEEE1394 standard for connecting digital cameras and video cameras to computers; Firewire connectors look very similar to Mini-USB connectors.
Hardware accessories such as digital cameras, flatbed scanners, Keyboard, Mouse, Printer, Video, etc. to use with a computer. Software (operating programs) must be loaded into the operating system so the computer knows how to use the Hardware that is plugged into it.
HDTV High Definition TeleVision: cheap solution to receiving over the air TV is A Direct Video Broadcast tuner with CD-program for computer. An Outdoor Over The Air antenna is necessary to receive most TV stations--use PH-FP100 to adapt the PAL antenna jack on a Artec DVB tuner to the F connection used on TV antennas
LAN Local Area Network: see also related terms: DB15, Ethernet, NIC, RJ45, and Thinnet.
NIC Network Interface Card: Hardware for connecting to other computers. A "3-Com Ethernet XL Combo" has BNC, DB15, and RJ45 connections. The BNC connection is for "ThinNet" wire. The RJ45 connection is for Cat 5 twisted pair wire to operate at 10M-bit/second on "older" Windows 95/98 era computers.
Pentium 2 Computers with this type of microprocessor on the motherboard operate around 200Mhz and usually have connectors for RJ45, (2) USB-A ports, (2) DB9 COM serial ports, HD15 Monitor connector, PS/2 style Keyboard & mouse jacks, DB25 Parallel (Printer) Port, and Sound Card connection jacks.
Plug-N-Play computer standard that allows USB Cables to connect hardware to 2000 & newer computers
PS/1 This late 1980's IBM 286 computer used a standard P5D (5 Pin DIN) "AT" connector for the keyboard and a PS/2 (Mini-DIN 6 pin) connection for the mouse.
PS/2 This term is commly used to refer to a Mini-DIN 6 pin male connector because the IBM 286 model PS/2 was the first really popular Personal Computer to use these plugs for both keyboard & mouse connections. Ken's Electronics stocks short adaptor cables to adapt keyboards & mouses with P5D plugs ("AT" style) to PS/2 plug devices to P5D plugs
RJ45 Eight Conductor Telephone type plug used tor "twisted pair" Local Area Network connections between computers. Cat-5, Cat-5E, or Cat-6 wire is used between RJ45 jacks in a building for Local Area Networks.
RS232 a standard for serial ports; DB25 connectors allow speed up to 115K-bits/second. Sometimes DB9 COMmunications serial ports are called RS232 connectors
Software operating instructions that enable a computer to work with Hardware plugged into it. Software can be purchased "over the counter" in computer stores. or may be custom designed by computer programmers.
Sound Card: (3) Stereo 3.5MM jacks (mate =P353 plug): Microphone (pink or black), Line Level Input (blue), Speaker Output (green). (4 connections): black=line level out. (6 or more jacks used with surround sound)
Thinnet Thin Ethernet Network wire: May be regular RG58 50 ohm coax or "Plenum Wire" (high temperature rated for running thru hot air ducts in commercial buildings). Computer Connection for this is a BNC female socket; Use a BNC-Tee connector at every computer with a "50 ohm terminator" (dummy load) at the unused ends of the BNC-Tee connectors. Operating speed of thinnet connections is 10M-bits/second or 1.2M-bytes/second with a limit of 180 meters of thinnet wire for a network of computers in a building.
VOIP Voice Over Internet Protocol: Hardware & Software to make "long distance" phone calls over the internet rather than paying a phone company "toll charges" to talk to somebody. This requires a high speed internet connection for reasonable sound quality.
PH70-025 Multimedia Headset Microphone . . . . $20,97
WAN Wireless Area Network: typically use the 2.4GHz cordless telephone band to connect computers together by radio signals. Comtelco makes a 3.5db gain omnidirectional antenna with normal N female connetor for the 2.4GHz band. D-Link Wireless G Router and Wireless G Desktop adaptor (802.11G 54Mbit) use reverse gender SMA antenna connectors. Link Sys sells 7db 2.4GHz antennas with reverse gender TNC connections. FCC rules for part 15 radio equipment requires that manufacturers use non-readily available connections so that individuals can't easily connect better antennas to their equipment to increase their range! There is another cordless telephone band at 5.8GHz; old stuff may be on the 900MHz band.
