a. I/O Hardware. Devices communicate with the computer via signals sent over wires or through the air. Devices connect with the computer via ports, e.g. a serial or parallel port. A common set of wires connecting multiple devices is termed a bus.

b. The main difference between interrupt and polling is that in interrupt, the device notifies the CPU that it requires attention while, in polling, the CPU continuously checks the status of the devices to find whether they require attention. In brief, an interrupt is asynchronous whereas polling is synchronous.

c. flash memory

A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage.

Harrizon [31]

Answer:

Check your DNS settings

Explanation:

Different errors may occur when setting up your computer to connect to the internet, one of which is described in the question above.

The DNS (Domain Name System) is responsible for redirecting domain names to their physical IP address. Instead of remembering every IP address of sites you visit frequently, domain names are used for easy remembrance, the DNS makes the matching of domain names to IP addresses possible.

  1. Click settings from your start menu
  2. Click on Network and Internet
  3. Look to the bottom of the main page and click on "Network and Sharing Center"
  4. On the left tab, click "Change adapter settings"
  5. Right Click on the current network you are using and select properties
  6. Left-click on the "Internet Protocol Version 4 (TCP/IPv4) and click on properties.
  7. Check to see if "Obtain DNS server address automatically" is selected, if it is selected,
  8. Click on the radio button under it "Use the following DNS server address"
  9. Enter the DNS address you want to use
  10. Click Ok and close the window.

The problem should be resolved.

kifflom [539]

Answer:

Let the computer warm up to room temperature before turning it on.

Explanation:

The laptop has been shipped to the user's home when he were at work and found on the deck. Outside it is really cool and he don't remember how long it has been there. Then, the user open his laptop and want to know whether it is functioning properly. Instead, let the machine warm up while switching it on to room temperature.

When a computer is still in a cold climate, they have to let it heat up to room temperature apx. 6-24 hours before switching it on. Otherwise, its heat the elements generate could cause water moisture within the laptop. That water could then harm elements of the system.
