some computer systems do not provide a privileged mode of operation in hardware. yes it possible to construct a secure operating system for these computers

This is theoretically possible by carefully monitoring and scrutinizing the output of just one process while it is being performed. To ensure that we are aware of each process's priority, we must take into account the fact that this will undoubtedly reduce the system's efficiency (it will function considerably more slowly) (which is rather hard if we do not have modes).

This type of equipment would require an operating system that could only operate in control (or monitor) mode. There are two ways that this could be done:

a. Software emulation of all user programs (such as some BASIC, Java, and LISP systems, for instance). What the hardware lacks, the software interpreter would supply in software.

b. Require meant that all programs must be written in high-level languages in order for compilers to output all object code. The protection checks for the missing hardware would be generated by the compiler (either internally or through function calls). It would be an absurdly difficult code.

Information that has been stored or transmitted in binary format and is admissible in court is known as digital evidence. Digital evidence is frequently linked to electronic crime, sometimes known as e-crime.

Processes and programs now executing on the system, network connections, signs of malware infection, registry hives, usernames and passwords, decrypted files and keys, and signs of activity not generally saved on the local hard disk are all examples of evidence that can be discovered in RAM. When dealing with the search and seizure of computers at a crime scene, law enforcement often just unplugs the computer and books it into the evidence center.

The accompanying graph depicts a hypothetical market for analog TVs.

In June 2009, the U.S. Federal Communications Commission (FCC) mandated that all over-the-air television broadcasts originating in the U.S. must be broadcast digitally instead of the traditional analog signal. These digital transmissions cannot be decoded by traditional analog TVs but require either a digital decoder be attached to an analog TV or a natively digital TV.

Both sellers and consumers were made aware of the upcoming switch from analog transmission to digital several years before the mandate took effect.

Demonstrate on the graph how the market for analog TVs changed immediately following the announcement of the switch to digital. For the supply side, focus on the end seller (such as an electronic store) of a TV and not the manufacturer.

When you employ an object-oriented language, you build programs by assembling a group of objects.

In contrast to functions and logic, object-oriented programming (OOP) organizes software design around data or objects. Objects can be defined as data fields with specific traits and behaviors.

Instead of focusing on the logic required to handle the objects, OOP focuses on the objects that developers want to control. This approach of programming works best with large, complex, and frequently updated programs. This encompasses mobile applications as well as design and production software. Software to simulate manufacturing systems, for instance, can be developed using OOP.

Due to object-oriented software's organizational structure, the approach is excellent for collaborative development when projects are broken up into groups.

IP addresses for the Internet are distributed by the Internet Assigned Numbers Authority (IANA).

The IPv4 addresses with four groups of numbers, with which we are most familiar today, are no longer available, according to the IANA. There are five global regions (sometimes referred to as RIRs) inside IANA, and each one provides IP addresses for devices within that region. On February 3, 2011, IANA distributed the final blocks/groups of IPv4 addresses, one block of /8 addresses, to each region. With each area being exhausted, this practically means that IANA is currently out of addresses. The first to expire in 2011 was APINC (Asia Pacific area).and have since assigned actions to prolong them as much as feasible. After that, LACNIC (Latin America) expired in 2014. In 2015, the free address pool of ARIN (North America) was depleted. On November 25, 2019, RIPE (region of Europe) expired.

Answer: the column or columns that contain values that uniquely identify each row in a table.

Among the three variables, speed is the proportionality constant. Regardless of the distance or location, the speed remains constant.

When two or more parameters are proportional to one another either directly or indirectly, their relationship is stated as a = kb or a = k/b, where k denotes the direction of the relationship between the two variables. The proportionality constant is thus k.

d= st

d = distance

speed is s.

t = time

Among the three variables, speed is the proportionality constant.

The speed is consistent over all locations and distances.

This can be expressed in various ways, as shown below.

d = st

S = d/t

t = d/s

There are other proportional relationships.

V stands for voltage.

The complete question is-

The equation y = kx represents a proportional relationship between x and y, where k is the constant of proportionality. For a moving object, the equation d = st represents a proportional relationship between distance (d) and speed (s) or between distance (d) and time (t). Explain the different ways that you can define the constant of proportionality for this equation. Then describe some other equations that represent proportional relationships in the real world and explain why they’re useful. Research on the Internet, if needed.

The largest common factor of the numbers GCF (145, 87) is 29 when remainder R = 0, the GCF is the divisor, b, in the equation. GCF = 29.

Do the division a ÷ b = c with remainder R given two whole integers where an is bigger than b.

Replace a with b, then R, and repeat the division.

Step 2 should be repeated until R=0.

When R=0, the greatest common factor, GCF, is the divisor, b, in the final equation.

Because the greatest common factor (GCF) and greatest common divisor (GCD) are interchangeable, the Euclidean Algorithm approach may also be used to discover the GCD.

145 ÷ 87 = 1 R 58    (145 = 1 × 87 + 58)

87 ÷ 58 = 1 R 29    (87 = 1 × 58 + 29)

58 ÷ 29 = 2 R 0    (58 = 2 × 29 + 0)

When remainder R = 0, the GCF is the divisor, b, in the last equation. GCF = 29

Since the remainder is zero, the algorithm stops and therefore, the GCF (145, 87) is 29.
