Answer:
The problem domain refers to the support options.
Is it asking for a web site like .edu? or something like that?
Answer:
System software is software on a computer that is designed to control and work with computer hardware. The two main types of system software are the operating system(Windows,Linux,Mac OS) and the software installed with the operating system, often called utility software (Anti virus, Disk formatting, Computer language translators) . In some cases, the operating system and utility software depend on each other to function properly.
Some system software is used directly by users and other system software works in the background. System software can allow users to interact directly with hardware functionality, like the Device Manager and many of the utilities found in the Control Panel.
Mechanical mouse has a ball that turns rollers inside. If friction is lost between the ball and the mousing surface, or between the ball and the rollers, the mouse fails to work. In order to assure good contact with the mousing surface, the ball must be fairly heavy. When you change directions with the mouse, you must make the ball change rolling directions--an action that inertia likes to prevent.
An optical mouse makes use of an LED and some optics to detect surface texture and the changes in it as the mouse is moved. There are no moving parts
Answer:
Following are the difference to this question:
Explanation:
IPv4:
The 
is uses the packet changed method, that is a Link Layer networks(like Ethernet). It has 4.3 billion addresses capacity. It uses the 32-bit logical device address, that written in decimal language.
It is divided by 4 bytes E.g. 192.168.1.1
The host part and network part are 2 parts. For a network, the host part may vary, while for the entire subnet, the network part remains equal.
The scheme of 232 addresses is available on application depends on security.
IPv6:
The IPv6 is used in the internet protocoland it is higher than IPv4. It can provide endless number Opf addresses, and use to solves the problem of IPv4 exhaustion and satisfies the demand for rising networking.
IPv4 Substitutor Built to meet more IP address requirements. In the Logical address of 128-bit Written hexadecimally and with colons divided, and the Space of 128 addresses are required. IPsec is an integrated security feature.
