Answer:
C)
Explanation:
One principle that can improve the efficiency of I/O would be to move processing primitives into hardware. Primitives are a semantic value representing something else such as words or numbers within the programming language. By moving them into hardware they system is able to read them at a much faster speed making the I/O more efficient.
Answer:
D. MAN
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a switch, a router, printer, etc.
On the other hand, a metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.
Basically, a metropolitan area network (MAN) spans across a geographic area such as a city and it's larger than a local area network (LAN) but significantly smaller than a wide area network (WAN).
In conclusion, the network type that the patrol services of a city's police department would most likely use is a metropolitan area network (MAN).
Answer:
Technician A is right 0 or 1 is called a bit
Explanation:
In computer language, Binary system is used in which data is shown either as 0 or 1.
A bit can hold either 0 or 1.
A byte can hold 8 bits of information.
Normally we use byte to represent computer storage.
A Kilo Byte (KB) can hold 1,024 bytes of information or 1,024*8 = 8,192 bits
A Mega Byte (MB) can hold 1,024*1,024 =1,048,576 bytes
or 1,048,576*8= 8,388,608 bits
Hence 0 or 1 is called a bit not byte therefore, Technician A is right!
