HOMEWORK: Bud, Not Buddy I NOTICE... What do you see? chpter 3-4

Answers

Answer:

Check Explanation for Chapter 3 - 4 Summary!

Explanation:

Chapter 3:

Bud tries hard not to panic in the pitch-black darkness of the shed. The eyeballs of three dried-out fish heads stare back at him as he tries the doorknob, which he hopes Mr. Amos only pretended to lock. While deciding where to lay his blanket and pillow, he remembers the story of the cockroach crawling into his best friend’s ear back at the Home. From the story his friend, Bugs, tells, the cockroach was yelling, “My legs! My legs! Why have they done this to my legs?” while adults tried to extract it with tweezers. Bud wants to avoid any encounters with the cockroaches that are surely crawling over the shed’s floor, ready to crawl in his ears. He spreads his blanket on the top of the woodpile and climbs up.

Bud attacks the bat with a rake, only to discover that he has disturbed a hornet’s nest. Hornets sting him as he grabs for the doorknob hoping for escape. In his haste, he forgets about the fish heads with their razor-like teeth. He screams as the teeth cut into him, and the hornets continue to sting. He manages to escape through a window above the wood pile and falls to the ground, slapping at the hornets still attacking him. He heads towards the Amoses’ house, set on revenge.

Chapter 4 Summary:

Bud climbs into the Amoses’ house through an unlocked window. He finds his suitcase still under the kitchen table and puts it on the back porch step. Back in the house, he grabs Mr. Amoses’ shotgun and hides it outside, so if the Amoses wake up, they wouldn’t use it on him.  

Bud returns to the kitchen. He fills a glass with warm water and heads up to Todd’s room. Todd is sound asleep. Bud dips Todd’s fingers in the warm water, hoping he’ll wet his bed. When he doesn’t, Bud pours the water on Todd’s pajama pants, causing Todd to soak his sheets. Bud creeps out of the house, grabs his suitcase, and heads toward the road, now “on the lam ... just like Public Enemy Number One.”

Which of the following accurately describes the overall trend in computing during the past 70-plus yearsa.
a. Toward physically larger, more powerful computers.
b. Toward physically larger, less powerful computers.
c. Toward physically smaller, less powerful computers.
d. Toward physically smaller, more powerful computers.
e. Toward physically smaller, single-use computers.

Answers

By simply reducing its size the computer can be speedier as indicated above, the concept of Einstein that messages can not spread faster than light speeds gives one of the limits to how quickly computers can work.

The computers have to become smaller to make them quicker. Therefore, Toward represents the total trend in the last 70+ years physically smaller, more powerful machines perfectly.

The wrong choice can be defined as follows:

For option a, it is wrong because physically larger computers acquire larger space.For option b, it is wrong because physically larger computers are acquiring in a larger space and it is more powerful.For option c, it is wrong because a small computer acquires a small space but it is less powerful as compared to physically larger.For option e, it is wrong because it is also known as a microcomputer that is powerful for both single and multiple users.

Therefore "Option d" is correct.

differentiate between standard and enhanced keyboard(10 diffrences)​

Answers

Explanation:

by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

A standard keyboard typically features a basic layout and functionality, while an enhanced keyboard includes additional features such as multimedia keys, customizable macros, and backlighting options.

The difference between standard and enhanced keyboards are as follows:

1) Key Layout: One of the primary differences between a standard keyboard and an enhanced keyboard is the key layout. A standard keyboard typically follows the traditional QWERTY layout, while an enhanced keyboard may have additional keys or modified key arrangements.

2) Extra Function Keys: Enhanced keyboards often feature additional function keys beyond the standard set found on a standard keyboard. These extra keys may provide quick access to specific functions like media controls, volume adjustment, launching applications, or controlling lighting effects.

3) Multimedia Controls: Enhanced keyboards often include dedicated multimedia controls for managing audio and video playback. These controls allow users to play, pause, stop, or skip tracks without the need to navigate through software interfaces.

4) Macro Keys: Enhanced keyboards may offer programmable macro keys that allow users to assign custom functions or complex sequences of commands to a single key press. This feature is commonly utilized by gamers or power users who require quick access to specific actions or shortcuts.

5) Backlit Keys: Many enhanced keyboards have backlit keys, allowing for improved visibility in low-light environments. These keyboards may offer adjustable backlighting levels or even customizable RGB lighting options for personalization.

6) Touchpad or Trackpad: Some enhanced keyboards include an integrated touchpad or trackpad, similar to those found on laptops. This feature eliminates the need for a separate mouse and provides cursor control directly on the keyboard.

7) Ergonomic Design: Enhanced keyboards often prioritize ergonomics by incorporating features like palm rests, adjustable tilt angles, or split keyboard layouts. These design elements aim to provide increased comfort and reduce the risk of repetitive strain injuries.

8) Connectivity Options: While standard keyboards usually come with a wired USB connection, enhanced keyboards may offer additional connectivity options such as wireless Bluetooth or specialized connectors like USB-C for faster data transfer.

9) Specialized Keys: Enhanced keyboards may have dedicated keys for specific purposes, such as gaming keyboards with keys optimized for gaming actions like WASD movement or mechanical keyboards with specialized switches for tactile feedback.

10) Software Integration: Enhanced keyboards often come with companion software that allows users to customize key functions, lighting effects, and other settings. This software integration provides additional flexibility and personalization options beyond what standard keyboards offer.
