Answer:
d.Responsive Display ads
e.Uploaded ads (Image & AMPHTML)
Explanation:
The two main ad formats used in a Standard Display campaign are;
1. Responsive Display ads: they are Google's new default ad format and are automatically created by Google using assets provided by users in a square and landscape format.
2. Uploaded ads (Image & AMPHTML): they are created using a tool like Google Web Designer to create adverts outside of Google Ads.
They can be uploaded as a jpeg, gif, zip file and png extension into Google Ads.
Answer:
A tape drive provides sequential access storage, unlike a hard disk drive, which provides direct access storage. A disk drive can move to any position on the disk in a few milliseconds, but a tape drive must physically wind tape between reels to read any one particular piece of data.
Explanation:
Architecturally tape drives are sequential storage, meaning that if you need to access some data at the end of the tape you needed to seek to the end and retrieve it. This can take seconds or minutes. Disks, OTOH are random access. Some hard drives use rotating media and movable heads , so the seek times are instantaneous , at least compared with tape drives. However, like tapes, there is a big advantage to using a rotating hard drive as sequential storage. It takes time, measured in milliseconds, for a head to move to another track. So traditionally, random access is much slower than sequential access.
SSDs have no internal moving parts so random access occurs in the same time frame as sequential access. Moreover, these drives usually have very high performance. For example, they can saturate a SATA data link, meaning that the SATA connection to the motherboard is now a bottleneck in disk access.
At one time tape drives were very popular. They were a low-cost alternative to using disks as backup. They were especially useful when IBM invented the Winchester “fixed” drive. This meant that the hard drive is fixed within its enclosure like they are today. Prior to this one could remove the drive pack and replace it. This was helpful when upgrading to a new version of the operating system as it was simple to replace the older drive pack should there be a problem.
Tape drives can be used in larger data centers, due to the fact that tape volumes can be removed and replaced so that the actual tape drive can backup many disk sets. Also the tape volumes can be stored off-site or in a fire-proof vault so this is valuable in a data recovery scenario.
Key exchange. If sending and receiving party did not agree on keys in an out-of-band way, the keys will have to be sent via the same channel as the encrypted data. Diffie-Hellman is an algorithm to let both sides derive the same key without physically sending it over the channel. An eavesdropper can listen in on the channel and still is unable to get the key.
The use of public wireless connections can increase a user's vulnerability to monitoring and compromise. <u>VPN </u> software can be used to encrypt transmissions over public networks, making it more difficult for a user's PC to be penetrated.
Explanation:
- A VPN, or Virtual Private Network, allows you to create a secure connection to another network over the Internet.
- VPNs can be used to access region-restricted websites, shield your browsing activity from prying eyes on public Wi-Fi, and more. .
- Virtual Private Network, is a private network that encrypts and transmits data while it travels from one place to another on the internet. VPNs aren't just for desktops or laptops, you can set up a VPN on your iPhone, iPad or Android phone.
- A VPN encrypts the traffic from your machine to the exit point of the VPN network. A VPN isn't therefore likely to protect you from an adversary like Anonymous.
- VPNs add another layer of encryption to your internet traffic, your latency will go up and speeds will go down.
Explanation:
The surface of the Cd contains a long Spiral track of data and a drive that shines a laser at the surface of the surface of the CD and can detect the reflective areas and the bumps by the amount of laser light they reflect.
The drive converts the reflection into 1s and 0s to read digital data from the disc. and hence playing what is on the disc
