The history of computers dates back to the late 1970s and early 1980s when personal computers became accessible to the general public. The invention of the microchip and microprocessor revolutionized computing by reducing the size and cost of computers, making them more affordable and accessible. Computers have since become an integral part of various sectors and continue to evolve in their capabilities.
Explanation:The history of computers dates back to the late 1970s and early 1980s when fully assembled personal computers became accessible to the general public. Previously, computers were only available as expensive kits that had to be assembled and programmed. The invention of the microchip in the 1970s revolutionized computing by reducing the size and cost of computers, making them more affordable and compact. Companies like Apple and IBM played a significant role in bringing personal computers to the market.
In the 1980s, the number of personal computers in the United States rose exponentially, and Apple introduced user-friendly interfaces like the Macintosh computer. The use of computers in various sectors, such as government offices, businesses, and homes, became widespread. The invention of the microprocessor further contributed to the affordability and accessibility of computers, allowing hobbyists and later a larger market to build and use their own computers.
The use of computers continues to evolve and impact various aspects of our lives, from communication and writing to complex computations and control of machinery.
What type of computer would integrate the system unit (chassis and computer) with the display and keyboard?
Final answer:
An All-in-One computer integrates the system unit with the display and keyboard into a single unit, saving space and reducing clutter. Examples include the iMac from Apple, as well as models from Dell, HP, and Lenovo.
Explanation:
The type of computer that integrates the system unit (chassis and computer) with the display and keyboard is called an All-in-One computer. An All-in-One computer is a desktop computer that has the display and keyboard built into the same unit as the system unit. This design saves space and reduces clutter on the desk as there are no separate components to connect.
One example of an All-in-One computer is the iMac from Apple. The iMac has a sleek design with the display and keyboard attached to a single unit. Other companies like Dell, HP, and Lenovo also offer All-in-One computers with different specifications and features.
All-in-One computers are commonly used in homes, offices, and schools where a compact and integrated design is preferred.
Given numrows and numcols, print a list of all seats in a theater. rows are numbered, columns lettered, as in 1a or 3e. print a space after each seat, including after the last. use separate print statements to print the row and column. ex: numrows = 2 and numcols = 3 prints: 1a 1b 1c 2a 2b 2c
To print a list of all seats in a theater with the given numrows and numcols, you could iterate over each row and column, combining the row number and the corresponding letter for the column. For example, if numrows = 2 and numcols = 3, the output will be '1a 1b 1c 2a 2b 2c '. Each seat is printed with a space after it, using separate print statements for rows and columns.
To solve this problem, you can use nested loops. The outer loop will run through the number of rows (numrows), and the inner loop will go through the number of columns (numcols). Since columns are lettered, you will have to convert the column index to a letter, which can be done by getting the ASCII value of 'a' and adding the column index to it, then translating it back to a character. After combining the row number and the lettered column, print the seat with a space. Repeat this process until all seats are printed.
b. Find Addition of Binary Numbers: 1100112 + 11012
Final answer:
The addition of binary numbers follows similar rules to decimal addition, with carrying over when sums exceed 1. For the binary numbers 1100112 + 11012, the answer is 1111002 after aligning by LSBs, adding bit by bit from right to left, and carrying as necessary.
Explanation:
The question asks for the addition of two binary numbers, specifically 1100112 and 11012. Binary addition works similarly to decimal addition, going from right to left with carrying over when a sum exceeds 1.
Step-by-step binary addition:
Align the numbers by the least significant bit (LSB, or the rightmost bit). Add extra zeros to the shorter number if necessary: 110011After performing these steps, the sum is found to be 1111002.
