MODERN COMPUTER EQUIPMENT.

MAIN CHARACTERISTICS

DESCRIPTION

Speed

Computers work at an incredible Speed. A powerful computer can perform 3 to 4 million simple instructions per second.

Accuracy

Errors that may occur can almost always be attributed to human error and not to the machine. Since it is a data-based system, errors are very rare.

Diligence

Computers are highly consistent because unlike us, they can’t be tired and therefore, no external situation can affect their efficacy.

Versatility

They can perform any task (only if it can be break into a series of logical steps), therefore, the range of performable activities does not limit to a single area.

Storage Capacity

They can store large volumes of data. The information stored in the computer, can never be forgotten and can be retrieved really fast.

Antivirus

The modern computer counts with antivirus, a program that will prevent, detect and remediate malware on computing devices and IT systems.

Type of system

The Operative System can be of 32 or 64 bits. The number of bits refers to the size of the data types that it handles and the size of its registry.

RAM

A computer uses a certain amount of RAM for fast-access storage of information and a much larger amount of non-random permanent storage than a hard disk drive.

• Multi user capability
• Multi-tasking capability
• High level communication between users

1. High Security: To protect data UNIX: Assigns passwords and login name to users; provides and execute permission to each file and encrypts files

• Portability: UNIX is a highly portable OS. It can be ported to many hardware platforms. It is the only system which has been ported across various hardware platforms such as IBM, DEC, HP and SUN. Most OS’s are written for one specific machine or platform only.
