Answer:
=F5*$F$12+F5
Explanation:
If we want to increment the salaries in the cell F5, we must multiply the cell F5 by cell F12, and then we must sum that result.
If we want to drag the formula from the cell F5 to F10, we must use the dollar symbol $ to apply the same percent in our formula.
For example:
F12 = 5% = 0.05
F5 = 10,000
=F5*$F$12+F5
=10,000×0.05+10,000 = 10,500
Answer:
computers and Mobile phones ( including game consoles and tablets) are managed through device management
Explanation:
Device management includes a type of security software used to monitor,secure and manage systems such as mobile phones computer laptops and desktops, Tablets and smart televisions as well as Game consoles. It as well involves the management,operation and maintenance of the physical aspect of the systems from external threats/intruders
Anti virus software is an example of a device management software used to protect systems from malware, by detecting and removing them and also by preventing them.
Firewall is a complete device management tool because it detects and prevents intruders and virus from penetrating the system software
Answer:
Disadvantages of public key cryptography is that : Assymetric cryptography is slower than the private key cryptography.
Explanation:
We are dealing with big data applications most of time. Almost all applications are data intensive. Private key cryptography which is also known as symmetric cryptography. Symmetric cryptography based systems are faster. Since there is no key transmitted with the data, encrypted data can be transferred over the channel or session even if the path is vulnerable or have chances of interception as the chances of decrypting the data is almost impossible.
Also, The identity of the receiver is guaranteed using the password based authentication used by symmetric crypto systems. Only the trusted receiver who has the access to the secret key can only decrypt the payload
Public Key Cryptography is slower than private key cryptography. Today’s application’s are data intensive. In case of data intensive applications , encrypting huge data will take a lot more time than that of symmetric key cryptography. Whenever Bulk data transmission is needed symmetric key cryptography is preferred. Secret key based crypto systems have proven to be more faster than any currently available assymetric key based crypto systems.
