Answer:

Option D: UNII-3

Explanation:

According to the 802.11 standard, 23 20MHz wide channels are defined in 5 GHz specturm. Each channel is 20MHz apart and they are separated into three Unlicensed National Information Infrastructure (UNII) bands. 802.11a/n/ac wireless devices can operate within these bands. In United States, UNII-3 is the upper UNII band that spans from 5.725 GHz TO 5.825 GHz and therefore it is the band that access point is operating. UNII-3 is not used in Europe countries for wireless communication.

The chips capacities express the word size, 16 bits, 32 bits, and 64 bits. The number of bits determined the amount of data it can process at one time

The specialty processors are specifically designed to handle special coprocessor and Graphics Processing Unit (GPU), like displaying 3D images or encrypting data.

A video card (also called a graphics card, display card, graphics adapter, or display adapter) is an expansion card which generates a feed of output images to a display device (such as a computer monitor).

network interface controller is a computer hardware component that connects a computer to a computer network. Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.

wireless network interface controller is a network interface controller which connects to a wireless network, such as Wi-Fi or Bluetooth, rather than a wired network, such as a Token Ring or Ethernet.

The standard SD card has dimensions of 32 mm by 24 mm by 2.1 mm, a storage capacity of up to 4 GB. Typical levels of performance are not as high as the other types of SD memory card mentioned below.

Which backup requires a small amount of space and is considered to have an involved restoration process?

dusya [7]

Incremental backup needs a small amount of space and exists considered to have an involved restoration process.

<h3>What is Incremental backup?</h3>

A backup or data backup exists as a copy of computer data taken and stored elsewhere so that it may be utilized to restore the original after a data loss event. The verb form, directing to the process of doing so, exists as "back up", whereas the noun and adjective form is "backup".

An incremental backup exists a backup type that only copies data that has been changed or made since the previous backup activity was conducted. An incremental backup approach exists used when the amount of data that has to be protected stands too voluminous to do a full backup of that data every day.

An incremental backup exists one in which successive copies of the data contain only the portion that has been modified since the preceding backup copy was made. When a full recovery is required, the restoration process would require the last full backup plus all the incremental backups until the point of restoration.

Hence, Incremental backup needs a small amount of space and exists considered to have an involved restoration process.

How do you fix this windows 7 screen

tensa zangetsu [6.8K]

Try restarting it. If you can’t restart because the screen is frozen maybe just turn it off and back on. If you already tried restarting and it still didn’t fix the problem, just give it some time. The computer will reset itself eventually which should fix the problem.
