Q

ROM vs. RAM

A

ROM- provides permanent storage for data and instructions that do not change, such as firmware—programs and data from the computer manufacturer, including the boot process used to start the computer. ROM stores data, using circuits with states that are fixed

RAM- Random access memory (RAM) is temporary, or volatile, memory that stores bytes of data and program instructions for the processor to access. RAM acts as the primary storage area in a computer for software and the data that it works with. RAM plays a crucial role in computer systems and can contribute to or detract from a computer’s performance

Q

Storage: Solid state vs. Optical vs. Magnetic

A

Solid state- device stores data using solid-state electronics such as transistors and, unlike magnetic and optical media, does not require any moving mechanical parts.

Optical state- media is convenient in terms of mobility but has limited storage capacity and is slow to write to.

Magnetic state- devices have high capacity and are convenient in terms of read and write ability, but they have slow data access rates due to the use of mechanical moving parts.

Q

Types of printers

A

Laser printer

A laser printer uses techniques similar to those of photocopiers to provide the highest-quality printed output. Color laser printers can be rather expensive, so many home users settle for either a less expensive black and white laser or a color ink-jet printer.

Ink- jet printer

An ink-jet printer sprays droplets from ink cartridges onto paper to create pixels. Although ink-jet printers create good-looking hard copy, it is not quite as polished as what laser printers provide. Also, ink may run if it gets wet, so use care when printing addresses onto envelopes and hope they aren’t delivered on a rainy day.

Photo printer

A photo printer is an ink-jet printer that is specially designed for printing photo-quality images on special photo-quality paper. Cameras can be connected directly to the printer and sometimes photos can be previewed and edited from the printer’s display.

Large format printer

Also called a plotter, this is a type of printer used for printing large graphics designs. Businesses typically use plotters to generate paper or acetate blueprints and schematics or to print drawings of buildings or new products on paper or transparencies.

Q

Advantages and disadvantages of cloud-based services

A

Advantages: The beauty of cloud computing is that users access services from their own computers or mobile devices but don’t have to be concerned with installation, maintenance, or security.

Disadvantages: Many cloud services are only accessible when the user is connected to the Internet. So, business travelers with intermittent Internet access could suffer. However, the amount of time anyone spends without Internet access is becoming less and less, and cloud service suppliers are working to support work offline. Another issue has to do with lack of control over the data. Some worry that cloud service companies will not adequately secure their data. They may also fear that sensitive information stored in the cloud could be subject to snooping eyes. In fact, government agencies have declined some cloud services because they do not meet government regulations for privacy and security.

52
Q

IoT

A

refers to the ability of physical objects to communicate over the Internet using embedded computing devices. (unit 3-1.8)

53
Q

IP address

A

The Internet Protocol (the “IP” in “TCP/IP”) defines the format and addressing scheme used for the packets. Routers on the Internet use the information in the packet header to direct the packet to its destination. The Transmission Control Protocol (the “TCP” in “TCP/IP”) enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and guarantees that packets are delivered in the same order in which they were sent. The Internet Protocol requires that all devices connected to the Internet have a unique IP address. An IP address is a unique 32- or 128-bit identifier for Internet users and hosts. Read as decimal numbers, a 32-bit IP address consists of four numbers (0 to 255) separated by periods, such as 64.233.161.104. IP addresses can be static (permanently assigned to a particular computer) or dynamic (assigned to computers as needed). Servers, such as www.facebook.com, use static addresses that don’t change, while clients that connect to the Internet, like your computer or cell phone, are almost always assigned temporary IP addresses that change either with each new connection or based on some time limit. For example, an IP address assigned by Comcast to a residential Internet account will change at least once a week. The current 32-bit IP address system (IPv4) can support 232, or roughly 4.3 billion, addresses. With a population of over 3 billion people online and growing, and many using more than one Internet-connected device, IP addresses are in short supply. Plus, the Internet of Things will significantly add to the demand. For these reasons, the Internet Assigned Numbers Authority (IANA) is in the process of moving Internet hosts to a new IP version, IPv6, which utilizes 128 bits to accommodate 3.403 × 1,038 addresses—an astronomical number of addresses, sufficient for the foreseeable future.

Q

Synchronous vs asynchronous

A

In synchronous communication, people communicate in real time, exchanging thoughts in a fluid conversation. Face-to-face conversations, video chat, telephone conversations, online chat, and instant messaging are examples of synchronous communication. Asynchronous communication allows participants to leave messages for each other to be read, heard, or watched and then responded to at the recipient’s convenience. Answering machines, voicemail, social network posts, text messages, tweets, and email are examples of asynchronous communication.
