A Byte?

Answer 13

A Bit = A single Binary Digit, having either the value 0 or 1, used to store or represent data.
A Byte = is 8 Bits, example 00110100

Question 14

Acronym: IDE?

Answer 14

Integrated Drive Electronics

On a Drive, it’s a Controller that translates requests from the PC into action, tells the heads where to read or write.

Question 15

Magnetic Storage?

Answer 15

Encodes data in patterns of positive and negative magnetic polarity on some magnetic medium.

Question 16

Optical Storage?

Answer 16

Store data in Reflectivity patterns on a shiny surface. Common Optical Disks include CDs, DVDs, and BDs. Unlike HDDs, Optical Disks are Removable from the drive that reads them.

Optical Disk is the Disk.
Optical Drive is the Drive that reads the Disk.

Question 17

Solid-State Storage?

Answer 17

Uses Nonvolatile (Flash) memory that can retain data when powered down. This technology has no moving parts. Solid-State storage is more expensive per gigabyte than disk-based storage, but it is also lighter, faster, quieter and more efferent.

Question 18

Local Storage?

Answer 18

Also called Direct Attached Storage (DAS), has direct internal or external connection to the device accessing it. Internal storage devices are physically located inside the main case of the computer and share its power supply.

Question 19

External Storage?

Answer 19

Connects to External Ports, some drives will draw all their power from the port, but others may need an additional alternating current adapter.

Question 20

Network Storage?

Answer 20

Network Storage or Hosted Storage is accessed over a LAN in your own home or office, a wide area network (WAN) with computers in different countries, or anything in between.

Question 21

Network-Attached Storage?

Answer 21

NAS typically describes a simple stand-alone device that connects one or more hard drive slots, a pared down file serve, and a network connection. Doesn’t have a keyboard, mouse, monitor, or full blown operating system, it just shares access to the installed hard drives.

Question 22

Ad Hoc Networks?

Answer 22

Connects devices directly without any “infrastructure” hardware such as a switch, router, or a server. Examples of Ad Hoc Networks include:

Direct Link - Two computers can be physically connected directly to one another via cables.
Wireless Network - In some cases you can use the wireless LAN adapters in two or more computers to create an impromptu network.
Bluetooth - Bluetooth device such as keyboard, mouse, headset or printer might connect directly to a computer, tablet, or smartphone.

Question 23

File Transfer Protocol Methods?

Answer 23

FTP - File Transfer Protocol
SFTP - Secure File Transfer Protocol, piggybacks on the SSH Protocol (Secure Shell)
FTPS - File Transfer Protocol over TLS/SSL (Transport Layer Security / Secure Sockets Layer)

Question 24

Web-Based File Downloads/Storage Types?

Answer 24

HTTP: - Hypertext Transfer Protocol
HTTPS: - Hypertext Transfer Protocol Secure over SSL, establishes an encrypted link between the Web Server and the User’s Browser originally using a Security Protocol called SSL (Secure Sockets Layer).

HTTPS-based web sites today use the more robust TLS (Transport Layer Security), but developers kept the original name of the protocol.

HTTPS Secure Websites are indicated with HTTPS at the beginning of the URL and with a LOCK Icon in the address bar.
