Computer Systems Flashcards
(64 cards)
Machine that uses electronic components and instructions to the components to perform:
1. Calculations
2. Repetitive and complex procedures
3. Process text
4. Manipulate data and signals
Computer
The largest type of computer
Super computers
First developed by Seymour Cray in 1972
Supercomputers
Designed primarily for analysis of scientific and engineering problems and for tasks requiring millions or billions of computational operations and calculations, they are huge and expensive.
Super computers
The most common fast, large, and expensive type of computer used in large businesses for processing, storing, and retrieving data.
Mainframes
It is a large multiuser central computer that meets the computing needs of large- and medium-sized public and private organizations.
Mainframes
The machines and software that process transactions in high-volume businesses are known as
transaction processing systems (TPS).
Computers designed to support a single user
Microcomputera
small, special function computers, although a few “full function” handheld computers were introduced in the late 1990s.
Handhel computers
Other name for microcomputera
Personal computer
refer to how the machine stores information at the lowest, or “closest to machine registers and memory,” level.
Bit and bytes
unit of data in the binary numbering system.
And Are grouped into collections of 8, which then function as a unit.
Bit
It is made up of 8 bits.
Byte
There are how many different combinations of 0 and 1 in an 8-character (or 1-byte) unit.
255
The CPU speed is measured in cycles per second, which are called the
Clock speed of the computer
One million cycles per second is called
1 megahertz MHz
is one important measure of the power of a computer
Clock speed
four types of cycles, or operations of a CPU:
Fetch
Decode
Execute
Store
A set of cooperative interconnected computers for the purpose of information interchange. The networks of greatest interest include local area networks (LANs), wide area networks (WANs), and the Internet, which is a network of networks.
Network hardware
defined as all of the physical components of a computer
Hardware
Examples of hardwares
CPU
Memory Card
Input and output devices
a square or rectangular board with circuits into which are plugged the main electronics of the
Motherboard
