What is CompTIA?
A not-for-profit, vendor-neutral organization that certifies the competency level of technicians through examinations written to test specific areas.
What is A+ Certification?
The certification awarded fro completing CompTIA which is recognized throughout the industry as a certification of basic PC repair and support skills.
What is this and by whom is it manufactured?
A CPU/Microchip made by AMD
What is this?
A scientific grade computer used for research and other demanding calculations. Also used widely for hosting servers such as with google’s large databases.
What is this?
A Dell home computer. Standard PC in todays world.
What are Digital Electronics?
Electronics in computers that use on and off conditions. The device either has full voltage or no voltage at all.
What are Analog Electronics?
Computer parts that produce and use a varying amount of voltage.
What is a Computer?
An assembly of electronic modules that interact with software to create, modify, transmit, store, and display data.
What is data?
Data is information such as text, graphics, and sounds.
What is a binary number system?
A form of code that consists entirely of ones and zeros, where ones mean a yes, or power, and zeros mean a no, or no power.
What is the hexadecimal number system?
A system of coding that uses 16 characters, numbers 0-9 and letters A-F
What is ASCII?
the American Standard Code for Information. The first attempt to standarize copmuter character codes among the varieties of harware and software. This helped create networks such as the letter k on a keyboard to the letter k on the monitor to the letter k being printed out of a printer. Today many key codes represent symbols on the Windows GUI through alt codes like ▲(Alt+3+0) which is done on the numpad.
What is a bit?
A bit is a single binary character of one or zero.
What is a byte?
A byte is a string of 8 bits, which was the original bandwidth used by computers.
What is a word in a computing sense?
A word is the total number of bytes a copmuter can process at one time. This will vary from computer to computer like in todays age most computer OS’s range from 32 to 64 bit processing bandwidth.
What is Serial Transfer?
Data being sent through a port one bit at a time in successive order.
What is Parallel Transfer?
A method of transfer where data is sent side by side, in bytes, or otherwise termed packets in networking.
What is a peripheral?
A peripheral is an optional piece of equipment used to display data or to input data. For example the mouse or keyboard right in front of you, or the monitor you’re reading this off of.
What is this a diagram of?
A motherboard, more specifically the I/O ports.
What does the term “Hot Swap” mean?
To plug in or unplug a device while the computer is running. For instance USB and FireWire ports are both hot-swappable.
What is a device bay?
A drive bay designed to accommodate the easy hot swap of devices such as hard drives, tape drives, and optical drives.
What is external SATA, or eSATA?
A port typically on motherboards today that provides a SATA grade connection, however it does not provide power to the SATA device.
What is a power eSATA port?
As the name implies, it is an eSATA port that also provides power to the device connected
What is a CPU?
A CPU, or Central Processing Unit, is the “brain” of the computer in simplest terms. It performs most all of the calculations on the computer and consists of millions of transistors that are electrically connected in such a way they are able to interact with computer programs and process data. Typically batches of cpu’s are made and they are cut from a “die”
