B. Computing devices are electronic.
C. The CPU processes commands.
D. The memory uses binary numbers
Answer:
A. Computing devices translate digital to analog information in order to process the information.
Explanation:
Computing is the process of using computer hardware and software to manage, process and transmit data in order to complete a goal-oriented task.
The true statements about computers are;
I. Computing devices are electronic: the components and parts which makes up a computer system are mainly powered by a power supply unit and motherboard that typically comprises of electronic components such as capacitors, resistors, diodes etc.
II. The CPU processes commands: the central processing unit (CPU) is responsible for converting or transforming the data from an input device into a usable format and sent to the output device.
III. The memory uses binary numbers: computer only understand ones and zeros.
Answer:
D. It makes it less likely that an error will be introduced into the code.
Explanation:
Answer:
Switches break up collision domains and routers break up broadcast domains.
Explanation:
- Collision domain depicts the part within a network where a collision can happen.
- Collision occurs when two hosts transmit data packet at the same time within a network. Theses packets collide and the hosts have to resend the data after some time.
- Too many collisions can result in slow traffic speed and can effect network performance.
- So switches break up collision domains between the devices on a network and each port in a switch depicts a collision domain. This reduces the chance of packet collisions between the devices or hosts.
- When data is to be sent to a host, the switch keeps that data frame and waits for availability of the destination host before sending the data frame.
- Moreover full duplex switch mode there is not chance of collision as the transmitting path on one host is the receiving path on other host.
- Broadcast domain contains all the hosts that can reach each other at the Data Link layer via broadcast.
- Routers break up broadcast domains as routers contain separate broadcast domains for each interface.
- Routers do not forward broadcasts from one broadcast domain to other and drop the packet when they detect a broadcast address.
